Description

Method for manufacturing horn vibrating piece using desizing original cloth

The invention relates to a method for manufacturing a horn vibrating piece, in particular to a method for manufacturing a horn vibrating piece using a desizing original cloth.

Please refer to FIG. 1 and FIG. 2 . FIG. 1 is a schematic view of a conventional horn. FIG. 2 is a perspective view of a conventional elastic wave. The typical moving coil horn 1 includes a diaphragm 1A, a suspension system and a power system. The diaphragm 1A functions to move air, typically a cone or hemispherical cone. The suspension system is composed of a structure such as a bomb wave 1B and a suspension 1C, and is used to guide the directional movement of the diaphragm 1A. The power system includes a voice coil 1D and a permanent magnet 1E, and can cause the diaphragm 1A to vibrate, so that the air vibrates and the audio is transmitted to the human ear, so that the sound is restored for the purpose of listening, and the conversion of electric energy to sound energy is realized. .

Generally, the non-metallic parts contained in the interior of the horn 1 are made of cloth, and the main reason is that the specially treated cloth has appropriate elasticity and strength, and can provide the functions required for the horn to operate, such as a diaphragm. 1A, the elastic wave 1B, the hanging edge 1C or the drum paper in the small horn are all the same, and such non-metal parts are collectively referred to as a horn vibrating piece. The conventional method for manufacturing the horn vibrating piece is to apply the pulverized raw cloth, and after the steps of impregnating the resin, drying, forming and cutting, the horn vibrating piece is formed.

Further, the original fabric is a fabric woven by warp and weft. In order to reduce the friction generated during manufacturing and prevent warp yarn breakage, in order to improve the efficiency and quality of the woven original fabric, it is necessary to first warp the warp sizing and increase the warp yarn. Conformity and smoothness. Therefore, the original cloth produced contains a slurry and is called a pulp-containing original cloth.

The main purpose of warp sizing can be summarized as the following seven points: (1) the twist of the fixed warp yarn; (2) the hairiness of the warp yarn; (3) increase the strength of the warp yarn; (4) increase the smoothness and softness of the warp yarn; 5) increasing the anti-charge prevention property of the warp yarn; (6) improving the weaving efficiency of the woven fabric; and (7) increasing the quality of the fabric.

However, since the slurry containing slurry affects the poor permeability of the resin and functional additives (for example, water repellent or flame retardant) to the original cloth, the resulting horn vibrating piece cannot be uniformly obtained. Hardness, elasticity, toughness, water/oil repellency and flame retardant/flame retardant/flame resistance.

The hardness, elasticity and toughness of the horn vibrating piece are not uniform, which means that the hardness, elasticity and toughness of some blocks are better, and the hardness, elasticity and toughness of some blocks are poor. The elastic restoring force and the fatigue resistance of the "better" hardness, elasticity and toughness are all superior to the elastic restoring force and the fatigue resistance of the block in which the hardness, elasticity and toughness are "poor". When used, the blocks with better hardness, elasticity and toughness and the blocks with poor hardness, elasticity and toughness will affect each other, so that the elastic restoring force and fatigue resistance of the horn vibrating piece made of the pulp-containing original cloth are not the same. Evenly. It should be noted that if the elastic restoring force and the fatigue resistance are not uniform, the horn vibrating piece will be easily deformed.

The water/oil repellency of the horn vibrating piece is uneven, which means that some blocks have better water/oil repellency, and some blocks have poor water/oil repellency. Even if the block with better water/oil repellency can prevent moisture, the block with poor water/oil repellency is vulnerable to moisture. In other words, the horn vibrating piece with uneven water/oil repellency has excellent water/oil repellency even in some blocks, but the horn vibrating piece is not damp as long as the block with poor water/oil repellency is damp. Water / oil effect.

The flame retardant/flame retardant/flammable resistance of the horn vibrating piece is uneven, which means that some blocks are more difficult to burn/flame retardant/flammable, and some blocks are poor in flame retardancy/flame retardant/flammability. Even if the block with better flame retardant/flame retardant/flammability resistance is resistant to high temperature and is not easy to burn, the block with poor flame retardancy/flame retardant/flammability is not resistant to high temperature and is easy to burn. In other words, the horn vibrating piece with uneven flame retardant/flame retardant/flammability resistance is excellent in flame retardancy/flame retardant/flammability resistance even if some blocks have excellent flame retardancy/flame retardant/flammability resistance. The block is not resistant to high temperatures and is easy to burn. Overall, there is no flame retardant/flame retardant/flame resistant effect.

The main object of the present invention is to provide a method for manufacturing a horn vibrating piece using a desizing original cloth, which can improve the permeability of the resin to the original cloth, so that the prepared horn vibrating piece has uniform hardness, elasticity and toughness and is uniformly obtained. Elastic recovery and fatigue resistance, and not easily deformed.

Another object of the present invention is to provide a method for manufacturing a horn vibrating piece using a desizing original cloth, which further improves the horn vibrating piece, and can improve the elastic restoring force and fatigue resistance of the horn vibrating piece, so that the horn vibrating piece The degree of deformation resistance is even higher.

A further object of the present invention is to provide a method for manufacturing a horn vibrating piece using a desizing original cloth, which can effectively prevent the original cloth from being severely shrunk after desizing, thereby obtaining the size of the desizing original cloth and the size of the original pulp-containing cloth. On the contrary, the total area of the horn vibrating piece which can be made by the desizing original cloth is almost the same as the total area of the horn horn piece which can produce the horn vibrating piece, and the number of the horn vibrating piece which can be manufactured is equivalent to that of the pulverized original piece. .

Referring to FIG. 2 and FIG. 3, FIG. 2 is a block diagram of a method for manufacturing a horn vibrating piece for applying a desizing original cloth according to the present invention, and the present invention provides a method for manufacturing a horn vibrating piece using a desizing original cloth, comprising the following steps. :

Sizing S1: A cloth material 10 is subjected to a sizing treatment to obtain a pulp-containing cloth 20. There are two ways of sizing treatment: a first sizing process S11 and a second sizing process S12, the details of which will be described later.

Desizing S2: The pulp-containing cloth 20 is subjected to a desizing treatment to obtain a desizing original fabric 21, wherein the desizing original fabric 21 is completely desizing or partially desizing. The desizing treatment adopts a hot water desizing method S21, an lye desizing method S22, an enzyme desizing method S23, and an oxidizing agent desizing method S24, the details of which will be described later.

Impregnated S3: The desizing original fabric 21 is impregnated with a resin solution 30. Specifically, the present invention provides a resin tank 31 in which a liquid resin 30 is contained, and the liquid resin 30 may be a phenol resin, an epoxy resin, a polyester resin, or the like. The liquid resin 30 contains a solid matter such as alcohol or water, and the content thereof accounts for 50% or more of the amount of the liquid resin. The desizing original fabric 21 is impregnated into the liquid resin 30 in the resin tank 31, and the warp and weft yarns in the desizing cloth 21 are adsorbed and adhered to the resin.

Drying S4: drying the desizing original fabric 21. More specifically, the desizing original fabric 21 is moved to a drying device 40, and the resin on the desizing original fabric 21 is dried, whereby the desizing original fabric 21 is provided with appropriate hardness, elasticity and toughness. Since the desizing original fabric 21 is completely desizing or partially desizing, the permeability of the resin to the original fabric can be improved. Wherein the permeability of the resin to the fully desizing desizing cloth 21 is superior to the permeability of the resin to the partially desizing desizing cloth 21, and the permeability of the resin to the partially desizing desizing cloth 21 is superior to that of the resin. The permeability of the pulp-containing cloth 20. Therefore, the desizing primary cloth 21 which is completely desizing has the most uniform hardness, elasticity and toughness, and obtains the most uniform elastic restoring force and fatigue resistance, and the effect of being easily deformed is the best. Although the degree of uniformity in hardness, elasticity and toughness of the partially desizing base fabric 21 is slightly inferior to that of the fully desizing pulp 21, it is still much more uniform than the pulp-containing cloth 20, so the desizing of the partial desizing is The uniformity of the elastic restoring force and the fatigue resistance of the original fabric 21 is superior to that of the pulp-containing original fabric 20, and is also less deformable than the pulp-containing original fabric 20.

Hot press forming S5: At least one horn vibrating piece predetermined shape 22 is hot pressed on the desizing cloth 21. More specifically, the desizing original fabric 21 is moved to a hot press forming apparatus 50. The hot press forming apparatus 50 includes a heating structure (not shown) and a forming mold 52. The forming mold 52 includes an upper mold 521 and a lower portion.

More specifically, the desizing original fabric 21 is moved to a cutting device 60, and the predetermined shape 22 of the horn vibrating piece is cut out from the desizing original fabric 21 by the cutting device 60 to obtain the horn vibrating piece 23. The horn vibrating piece 23 made of the desizing original cloth 21 which is completely desizing has the most uniform hardness, elasticity and toughness, and obtains the most uniform elastic restoring force and fatigue resistance, and is not easily deformed. The horn vibrating piece 23 made of the partially desizing desizing cloth 21 has a degree of uniformity in hardness, elasticity, and toughness slightly lower than that of the horn vibrating piece 23 made of the desizing original cloth 21 which is completely desizing, but Still more than the horn vibrating piece made of the pulp-containing original cloth 20, the horn vibrating piece 23 made of the partially desizing backing original cloth 21 has better uniformity of elastic recovery and fatigue resistance than the slurry. The horn vibrating piece made of the original cloth 20 is also less deformable than the horn vibrating piece made of the sizing original cloth 20.

Modification S7: The horn vibrating piece 23 is first wetted and then dehydrated to obtain a modified horn vibrating piece 24. More specifically, the horn vibrating piece 23 obtained by cutting off the step S6 is moved to a vapor device 70, and the steam device 70 generates a water vapor, and the water vapor adheres to the horn vibrating piece 23 to make the entire horn vibrating piece 23 Wet evenly. However, the means for the wetting treatment of the horn vibrating piece 23 is not limited thereto, and any means for allowing the horn vibrating piece 23 to be wet is encompassed in the scope of the present invention, which will be described first. Next, the horn vibrating piece 23 is removed from the steam device 70 to remove water, and the water vapor of the horn vibrating piece 23 is completely removed, so that the obtained horn vibrating piece 24 is uniformly modified as a whole. The modified horn vibrating piece 24 has the same degree of deformation resistance as a whole. Means for removing water include, but are not limited to, draining excess water with a tumble or scraper. Preferably, the wet processing time and the water removal treatment time of the horn vibrating piece 23 are not more than 24 hours.

And the water-repellent agent; in the step of impregnating the flame retardant S8, the dried desizing cloth 21 is immersed in the flame retardant; in the step of impregnating the water-repellent agent S9, the desizing original cloth 21 is immersed in the water-repellent agent; In the step of moisturizing S10, the desizing original fabric 21 is centrifugally dehydrated at a normal temperature by a centrifuge (not shown), and the desizing original fabric 21 is leached by a roll (not shown) or a scraper (not shown). Excess water. Therefore, the modified horn vibrating piece 24 has water/oil repellency and flame retardancy/flame retardant/flame resistance.

In a third embodiment, a water repellent impregnation step S9 and a dehumidification S10 step are added between the drying step S4 step and the hot press forming step S5, and the functional auxiliary agent is a water repellent agent. In the step of water-repellent impregnation S9, the dried desizing original cloth 21 is immersed in the water-repellent agent; in the step of removing water and moisturizing S10, the desalted original cloth 21 is centrifugally dehydrated and centrifuged at a normal temperature by a centrifuge. Or scrape the excess moisture of the desizing cloth 21. Therefore, the modified horn vibrating piece 24 has water repellency/oil repellency.

Since the desizing original fabric 21 is completely desizing or partially desizing, it is possible to improve the permeability of the functional auxiliary agent such as a water repellent or a flame retardant to the original fabric. The permeability of the functional additive to the desizing pulp 21 which is completely desizing is superior to the permeability of the functional auxiliary to the desizing original fabric 21 which is partially desiccated, and the functional auxiliary is the desizing of the partial desizing. The permeability of the cloth 21 is superior to the permeability of the functional additive to the pulp-containing cloth 20. Therefore, the distribution of the functional auxiliaries is most uniform in the desizing primary cloth 21 which is completely desizing, followed by the desizing original fabric 21 which is partially desizing, and the worst is the sizing original cloth 20. Therefore, the effect of the functional additive (for example, water/oil repellency or flame retardancy/flame retardant/flame resistance) can be modified by using the completely desizing backing original cloth 21 to form the horn vibrating piece 24 The most uniform presentation, the application of the enhanced functional additive to the modified horn vibrating piece 24 is the best, followed by the modified horn vibrating piece 24 made of the partially desizing desizing original cloth 21.

The desizing treatment of this embodiment adopts the enzyme desizing method S23, and the enzyme is desizing. Method S23 contains the following substeps:

Desizing liquid impregnation S231: The slurry containing original cloth 20 is immersed in the desizing liquid. Specifically, the present invention provides a desizing solution tank 141 containing a desizing solution 140, which includes, but is not limited to, 0.5 to 1% of an enzyme desizing agent and 0.1 to 0.2% of a nonionic penetrating agent, and a pH of the desizing solution 140. The value is 6~7 and the temperature is 80~85 degrees Celsius. The desizing liquid 140 in which the pulp-containing cloth 20 is immersed in the desizing tank 141 is about 30 to 60 seconds. For example, when the slurry 80 is starch, the enzyme desizing agent is an amylase. Commonly used amylases include pancreatic amylase and bacterial amylase. The main components of these two enzymes are α-amylase, which can cause the cleavage of the long-chain molecules of starch to break, produce dextrin and maltose and easily wash from the original cloth. except.

Drying S235: The desizing original fabric 21 was moved from the desizing tank 100 to the drying device 110 and dried at a temperature of 100 ° C for 10 minutes.

Please refer to FIG. 8A, FIG. 8B and FIG. 8C. FIG. 8A is a block diagram showing the desizing step of the horn vibrating piece manufacturing method of the desizing original fabric of the present invention, wherein the desizing treatment adopts an oxidizing agent desizing method; FIG. 8B is The schematic diagram of the sizing step and the desizing step of the method for manufacturing the horn vibrating piece of the desizing original fabric of the present invention, wherein the sizing treatment adopts the first sizing process, and the desizing treatment adopts the oxidizing agent desizing method; 8C is a schematic flow chart of a sizing step and a desizing step of the horn vibrating piece manufacturing method of the desizing original cloth of the present invention, wherein the sizing treatment adopts a second sizing process, and the desizing treatment adopts an oxidizing agent desizing method. . The first sizing program S11 and the second sizing program S12 are as described above. The slurry-containing original cloth 20 subjected to the first sizing process S11 or the second sizing process S12 is subjected to a desizing treatment in the desizing step S2. The desizing treatment of this embodiment uses an oxidizing agent desizing method S24, and the oxidizing agent is desizing. Method S24 includes the following substeps:

Desizing liquid impregnation S241: The slurry-containing original cloth 20 is immersed in the desizing liquid 140. Specifically, the present invention provides a desizing tank 141 containing a desizing liquid 140 therein. When the desizing liquid 140 comprises 3~5% hydrogen peroxide desizing agent, 5g/l sodium hydroxide and 5g/l surfactant, it can degrade the starch, polyvinyl alcohol and the like, and has a certain degree of bleaching effect. . When the desizing liquid 140 is sodium bromate and the pH is 9.5 to 10.5, it is piled at room temperature for about 20 minutes, and the pulp-containing original cloth 20 is a slurry 80 for carboxymethyl cellulose, starch or polyvinyl alcohol. Has a good desizing effect. When the desizing liquid 140 is an ammonium sulfate salt or a potassium salt, it also has a good desizing effect, but it is easy to cause the cellulose fiber to be brittle.

The pressure suction S242: the pressure-containing suction device 20 pressurizes the slurry-containing original cloth 20.

First drying S243: The slurry-containing cloth 20 was transferred from the pressure suction device 150 to the drying device 110 and dried at a temperature of 105 ° C for 10 minutes.

Heat treatment S244: The slurry-containing cloth 20 is heat-treated at a temperature of 95 to 100 degrees Celsius for 40 minutes by a heat treatment device 160.

Washing S245: The slurry-containing cloth 20 is transferred from the heat treatment apparatus 160 to the desizing tank 100 for a few hours, and the water is washed away together with the slurry 80 by the water to obtain the desizing cloth 21.

The second drying S246: The desizing original fabric 21 is moved from the desizing tank 100 to the drying device 110 and dried at a temperature of 105 degrees Celsius for 10 minutes.

However, the problem that the original cloth shrinks after desizing causes the size of the desizing original fabric 21 to be smaller than that of the original pulp-containing cloth 20, so that the total area of the desizing original cloth 21 capable of producing the horn vibrating piece is smaller than originally estimated. Therefore, the number of horn vibrating pieces that can be manufactured is less than originally expected. The following two possible solutions are revealed:

Solution one:

The invention further comprises a pre-processing step S0, the pre-processing S0 step being arranged before the sizing S1 step. In the pre-treatment S0 step, the cloth raw materials 10, 10' are a plurality of warp yarns 11, 11' and a plurality of weft yarns 12, 12', and the fiber materials used for each of the warp yarns 11, 11' and each of the weft yarns 12, 12' are Low shrinkage fiber with a boiling water shrinkage of less than 5%.

In a preferred embodiment, the fibrous material is subjected to a low shrinkage treatment. More specifically, the low shrinkage treatment adds a low shrinkage agent to the fibrous material before forming, and the internal shrinkage of the fibrous material is released by the low shrinkage agent to compensate for the polymerization shrinkage, thereby reducing the shrinkage of the fibrous material, so that the fibrous material is obtained. After forming, it is formed into a low shrinkage fiber having a boiling water shrinkage of less than 5%.

Among them, the principle of action of the low shrinkage agent is the principle of phase separation. The phase separation of the low shrinkage agent from the fibrous material is a necessary condition for creating voids and resisting shrinkage. The specific process is as follows:

First, the material is heated and begins to expand thermally.

Second, an increase in temperature causes the initiator to decompose and solidification begins.

Third, the compatibility of the fibrous materials becomes incompatible and begins to form two phases.

Fourth, the reactive low shrinkage agent and the fibrous material are collected in the thermoplastic.

Fifth, as the polymerization proceeds, the temperature and degree of polymerization increase. As the temperature increases, the fiber material phase shrinks, and the volume occupied by the low shrinkage agent and the unreacted monomer increases, compensating for the polymerization shrinkage.

Sixth, the monomer in the low-shrinkage agent phase begins to react, and the pressure caused by the polymerization generates micro-cavities.

Finally, cooling is initiated, and above the glass transition temperature above the fiber material, the coefficients of thermal expansion of the low shrinkage agent phase and the fiber material phase are substantially equivalent. Below the glass transition temperature below the fiber material phase, the cold shrinkage of the fibrous material phase is much less than the cold shrinkage of the low shrinkage agent phase. The difference in this cold shrinkage is caused by the generation of micro-cavities in the low-shrinkage phase as much as the micro-cavities generated by the stress at the periphery of the low-shrinkage agent phase until the glass transition temperature of the low-shrinkage agent is reached.

Preferably, the low shrinkage agent is a non-polar low shrinkage agent, a weakly polar low shrinkage agent, a polar low shrinkage agent or a combined low shrinkage agent.

Non-polar low shrinkage agents include, but are not limited to, solid powder low shrinkage agents such as polystyrene (PS), polyethylene (PE), polypropylene (PP). The non-polar low-shrinkage agent has a two-phase system with the fiber material before the fiber material is solidified, and simply utilizes the thermal expansion property of the fiber material (especially the fiber material formed of the thermoplastic resin) to suppress the curing shrinkage of the fiber material, but the low shrinkage property. More general.

Weakly polar low shrinkage agents include, but are not limited to, polymethyl methacrylate (PMMA), cellulose acetate butyl acetate, polyvinyl chloride, and the like. The weakly polar low shrinkage agent has improved stability in the fiber material due to the increase in polarity, so that the phase separation structure of the weakly polar low shrinkage agent and the fiber material is improved upon curing. It should be noted that although the polarity of PVC is relatively strong, its glass transition temperature (Tg) is 87 degrees Celsius, the viscous temperature is as high as 165-190 degrees Celsius, the phase separation effect is not good, and the low shrinkage effect is poor.

Polar low shrinkage agents include, but are not limited to, polyvinyl acetate (PVAc), saturated polyester, polycaprolactone, polyurethane, and the like. The polarity of the low shrinkage agent is similar to that of the unsaturated polyester and has good compatibility with the fiber material. Before the curing, it is a homogeneous system with the fiber material, and is uniformly phase-separated after curing. The shrinkage control of the curing of the fibrous material can be achieved to the highest extent.

Combined low shrinkage agents include, but are not limited to, graft type core shell polymers, block type polyvinyl acetate styrene (PVAc-St), modified light crosslinked polystyrene, inorganic modified low polarity Shrinking agent, etc. The combined low shrinkage agent has excellent comprehensive properties, excellent low shrinkage, outstanding microscopic interface, good mechanical properties and minimal molecular permeability.

Preferably, the low shrinkage fiber having a boiling water shrinkage of less than 5% is cotton fiber, crepe, low shrinkage polyester fiber or low shrinkage polypropylene fiber, which is not limited thereto.

This scheme is suitable for the fully desizing of the desizing original fabric and the partially desizing of the desizing original fabric.

Solution two:

In the step of desizing S2, 96.5%~98.5% of the slurry 80 in the pulp-containing original cloth 20 is removed to obtain a partially desizing pulping original cloth, which still contains 1.5 to 3.5% of the pulp. Material 80.

Both of the above solutions can effectively prevent the original cloth from being severely shrunk after desizing, so that the size of the desizing original fabric 21 obtained is equivalent to the size of the original pulp-containing cloth 20, so that the desizing original fabric 21 can produce the horn vibration. The total area of the sheet is almost the same as the total area of the horn-containing cloth 20 capable of producing the horn vibrating piece, and the number of horn vibrating pieces that can be produced is comparable to that of the sizing-containing cloth 20. Among them, the effect of the first solution is particularly preferable.

Referring to FIG. 9, FIG. 9 is a perspective view of a horn vibrating piece such as a suspension, a diaphragm, and a spring wave produced by the horn vibrating piece manufacturing method of the desizing original fabric of the present invention. The modified horn vibrating piece 24 may have a structure such as a diaphragm 1A, an elastic wave 1B, and a hanging edge 1C.
