Description

MANUFACTURING PROCESS OF CHAIR COVER USING FLAME RETARDANT YARN, AND CHAIR COVER THEREOF

The present invention relates to a method for manufacturing a chair outer bag using flame retardant yarn and a chair outer bag manufactured by the method, in particular used as a cover of a connection chair installed in a pulpit, a performance hall, a train, etc. The present invention relates to a method of manufacturing a chair envelope, and a method of manufacturing a chair envelope.

In general, a connected chair installed in an auditorium, a performance hall, or a train includes a cushioned and soft cloth or seat on the surface of the chair to provide cushioning and comfort. Hereinafter, the cloth or seat will be referred to as a chair envelope.

The outer envelope is generally manufactured in the form of sheets by weaving natural or chemical fibers with a weaving machine or circular knitting machine, and cutting and sewing them into the appropriate size and shape to cover the surface of the chair. In addition, since toxic gases are emitted during combustion, it is preferable to install a non-flammable or flame retardant envelope in a connected chair such as an auditorium, a performance hall, or a train.

Flame retardancy refers to a property that is not easily burned, that is, it is burned (self-extinguishing) as it melts while holding a flame, is naturally extinguished when released from a flame, and emits toxic gas during combustion. Since there is little, it is possible to prevent suffocation by toxic gas in case of fire.

In the past, the method of manufacturing a flame retardant envelope was provided with a flame retardant coating on the surface of the envelope wrapped with ordinary fibers to coat a flame retardant chemical, thereby imparting flame retardancy to the fabric. Flame retardant durability is not good because the flame retardant coating layer is removed and the flame retardancy is significantly lowered, and since the flame retardant is a toxic chemical, when the flame retardant is coated, the workers are exposed to harmful environments and the flame retardant flows into sewage or into the atmosphere. There was a problem that is released to cause environmental pollution.

As a more improved form, there is a form of weaving the fabric directly into the flame retardant yarn, for example, in the prior art related to this, Korean Patent No. 10-0639793 (hereinafter referred to as 'prior art 1') in addition to the basic warp and weft yarn A flame retardant fabric prepared by applying a low melt polymer which is fused at a low temperature to an outer surface of the flame retardant yarn preparation process, a flame retardant yarn dyeing process, a weaving process, a dyeing process, a heating process and a drying process has been proposed.

However, flame retardant yarn has lower melting temperature than ordinary fiber yarn, so the fabric is not easily fused (shrink and harden) during dyeing such as boiling at high temperature, or tenter treatment such as heating and drying. Considering this, since the prior art 1 is manufactured by two dyeing processes and a final heating and drying process, the flame retardant fabric cannot exhibit vivid colors and soft textures, and it is difficult to manufacture a fabric in which hair is formed. There are bound to be restrictions on use. That is, the envelope used for the connected chair as in the present invention should not only have a flame retardant property, but also a touch or color should satisfy a level desired by the consumer. However, the fabric of the prior art 1 has only flame retardant properties, and various consumer needs, In other words, it does not meet the fabric with a vivid color and texture, and a soft touch has a very limited use.

As another conventional technology, Korean registered patent No. 10-0760800 (hereinafter referred to as 'prior art 2') is flame retardant weaving, washing, softening treatment, primary tenter, brushing, washing, dyeing, and secondary tenter. It was proposed a flame retardant stage membrane and a method for producing the excellent wash durability.

However, when the softening agent is treated to a fabric woven with flame retardant yarn, it is not preferable because it impairs flame retardancy. Furthermore, after the brushing process of forming the hair on the surface of the fabric woven with flame retardant yarns, the dyeing process and the secondary tenter (heat treatment) process at high temperature are performed to raise the brushing process due to the characteristics of the flame retardant yarn having a low melting point as described above. Hair is fused and it is impossible to produce a fabric with the desired vivid color.

Therefore, in the prior art, when a pre-raising process and a post-dyeing process are performed on a fabric woven with flame retardant yarn as in the prior art 2, a tumbling process of re-establishing the finally fused hair had to be performed. This is a problem in that the cost increases due to the addition of the manufacturing process.

An object of the present invention devised to solve the above problems of the prior art is to manufacture a chair outer bag using a flame retardant yarn, weaving a fabric in which a loop-shaped loop (loop) tissue is formed to loop in a subsequent dyeing or tenter process By minimizing fusion or lying down of the tissue, and finally cutting the upper linkage of the loop tissue through the shearing process, it has a vivid color and soft texture, and it is eco-friendly and can be cleaned by eliminating the use of chemicals such as flame retardants. Another object is to provide a chair envelope that does not impair flame retardancy.

The present invention for achieving the above object is a method of manufacturing the outer wrapper of the chair by weaving a flame retardant yarn, flame retardant weaving weaving a fabric in which a loop-shaped loop (loop) structure is formed on at least one side using a flame retardant yarn step; Dyeing the dye using a dye on the fabric; A washing step of washing the dyed fabric; A tenter step of heating and exposing the washed fabric; And a shearing step of cutting the loop top of the tentered fabric.

As a deformable embodiment of the present invention, in the flame retardant yarn weaving step, loops are formed on both sides of the fabric, and the shearing step cuts the loops formed on one side of the fabric or cuts the loops formed on both sides. It is done.

The chair envelope of the present invention obtained by such a manufacturing method forms a looped loop structure, and the fabric formed by the pre-dyeing and post-shearing process can maintain the original form without fusion or lying down. Its vivid color and texture doesn't interfere.

According to the present invention, after weaving the outer envelope in which the loop-shaped loop tissue is formed using flame retardant yarn, the dyeing and post-shearing process are performed. Due to the nature of the loop tissue, the fusion or death of the loop tissue can be minimized, and the loop tissue linkage is cut at the final shearing stage to produce a chair envelope that is not impaired by the vivid color and soft texture of the fabric.

Due to this process sequence, the conventional tumbling process can be eliminated, thereby reducing the production cost due to the shortening of the manufacturing process, and since weaving pure flame retardant yarn directly, it is eco-friendly because it does not use chemical substances such as flame retardants. In addition, since the flame retardancy is not degraded even when washing, there is an advantage that can satisfy various needs of consumers for the product.

In addition, by eliminating the use of chemicals, there is an advantage that the working environment is pleasant and does not emit environmental pollutants.

Hereinafter, with reference to the accompanying drawings will be described in detail a manufacturing method of the chair outer bag of the present invention.

1 is a block diagram showing a chair outer bag manufacturing process according to the present invention, Figure 2 is a cross-sectional view of the tissue formed by the weaving process of the chair outer bag manufacturing process according to the present invention, Figure 3 is a chair outer bag according to the present invention It is sectional drawing of the structure formed by the Sharing process during a manufacturing process.

As shown in Figure 1, the method for manufacturing a chair outer bag using the flame retardant yarn of the present invention, flame retardant weaving step of weaving a fabric in which a loop (loop) structure of the loop shape is formed on at least one side using the flame retardant yarn ( S1), a dyeing step (S2) of coloring the fabric using a dye, a washing step (S3) of washing the dyed fabric, and a tenter step of heating and exposing the washed fabric ( S4) and a shearing step S5 of cutting the loop top of the tentered fabric.

The flame retardant yarn is burned (self-extinguishing) while being melted while applying a flame, and has a property of being naturally extinguished when fired from the flame, and a flame retardant yarn having such characteristics can be manufactured in various known forms. The flame retardant yarn may be, for example, a chemical fiber yarn obtained by copolymerizing a separate flame retardant material with a synthetic resin such as polyester, acrylic, polypropylene, and the like, and as another example of manufacturing a flame retardant yarn, refer to the method of manufacturing flame retardant yarn described in Korean Patent No. 0405644. As described above, the flame retardant yarn of the present invention may be selected from known production methods or commercially available ones, and the production method is not limited thereto.

According to the invention weaving the fabric (loop) is formed by using a flame retardant yarn having the flame retardant properties (S1). When weaving the fabric, as shown in Figure 2, the loop tissue is to produce a fabric having a vivid color and a smooth texture by weaving flame retardant yarns in a snare or ring shape on one side. They are elastic and flexible because they are interconnected in a loop. Weaving of woven fabrics with looped tissues often employs the technique used to weave towels, and can be implemented in conventional weaving machines or circular knitting machines. However, looped fabrics are different from brushing or raising techniques that scrape the surface of tissues of a fabric or knit fabric and cause fine hairs or naps to the surface.

In other words, the lint or hair formed by raising is to scrape the surface of the fabric, so the thickness is thinner than the thickness of the fabric of the fabric and the thickness is not constant. There is a fear that it may not exhibit the vivid color or texture inherent in the fabric formed by brushing. On the other hand, the loop (loop) is because the yarn with the inherent thickness of the flame retardant yarn as it is connected in the form of a snare or ring, there is an advantage that the fusion is not easy even under the high temperature environment of the dyeing and tenter process of the post process.

According to the present invention, the loop (loop) tissue, unlike the form shown in Figure 2, may be formed on both sides of the fabric at the same time, it can also be woven by manipulating the device in a circular knitting machine or a weaving machine.

In this way, after the fabric having a loop structure is formed on one side or both sides of the fabric, the dyeing step (S2) for coloring itself is made. Dyeing is the process of permanently fixing color using organic dyes, which takes place at high temperature and high pressure. The dyeing process is not particularly limited. Generally, the dyeing process is performed by preparing a fabric, performing a quenching process, putting it into a dyeing machine, neutralizing, refining, bleaching, and coloring, and adding or deleting other processes as necessary. It is satisfactory to carry out the usual dyeing process, for example.

The washing step (S3) is a process of washing the remaining dye or foreign matter without coloring from the fabric of the dyeing process (S2) is completed using high temperature water of about 100 ℃.

The tenter step (S4) is a kind of exposing step of drying the desired or desired processing width of the fabric through heat treatment, such as a kind of ironing. In other words, the fabric is stretched in one direction due to the nature of the process of the dyeing or washing step, so that the width is narrower, it is necessary to make the width close to the original width, at this time tenter.

When weaving a fabric in which a loop-shaped loop structure is formed by using a flame retardant yarn as in the present invention, heat fusion or deformation in dyeing, washing, and tenter processes can be minimized as compared to fluff formed by brushing.

Finally, in the shearing step (S5), the shearing is to cut the upper end of the loop (loop) tissue formed on the surface of the fabric using a shearing machine (Shearing machines), as shown in Figure 3, the shearing When the loop is connected to the loop-shaped upper part is broken so that one loop is transformed into two hairs, the color of the fabric as shown in Figure 4 shows a clear and smooth texture.

Figure 4 is a photograph showing the surface of the fabric before and after the shaling process of the chair outer wrapper manufacturing process according to the present invention, as shown in Figure 4 the fabric (Before) before going through the shearing step (Before) is in the form of a loop surface On the other hand, the rough and non-shiny fabric (After) has a relatively rough surface and is shiny because it has a vivid color and texture that consumers prefer.

Thus, according to the present invention, weaving the fabric in which the loop-shaped loop structure is formed, and pre-dyed and post shearing, so that the loop tissue is fused or laid down in the dyeing process and the tenter process. The final shaling process also allows for the production of chair envelopes with a more vivid color and texture than the original looped fabric.

According to the present invention, when a loop structure is formed on both sides of the fabric as described above, the shearing step (S5) may be processed for only the loops on either side of the loop structure on both sides. If necessary, all the loops formed on both sides can be shredded, which can be appropriately selected depending on the purpose and purpose of the fabric.

Although the above has been illustrated and described with respect to preferred embodiments of the present invention, the present invention is not limited to the above-described specific embodiments, it is usually in the technical field to which the invention belongs without departing from the spirit of the invention claimed in the claims. Various modifications can be made by those skilled in the art, and these modifications should not be individually understood from the technical spirit or the prospect of the present invention.
