Description

Woven cloth containing two different kinds of threads and clothes containing same

technical field

The present invention relates to a woven fabric containing two different kinds of filaments and clothes comprising the woven fabric. Described in more detail, the present invention relates to a fabric containing two different types of filaments that increases the porosity of the fabric structure due to moisture absorption and improves air permeability, and decreases the porosity of the fabric structure and decreases air permeability due to drying. woven fabrics and clothes comprising the woven fabrics. the

The woven fabric containing two different types of filaments of the present invention can prevent discomfort caused by wet clothes due to perspiration and decreased air permeability when worn. the

Background technique

In the past, woven fabrics made of synthetic fibers or natural fibers were used for sweating when worn, but if they were used as sportswear or underwear, for example, there were problems of discomfort caused by sweating and decreased air permeability. . the

As a means of eliminating the discomfort caused by sweating in this way, a breathable self-adjusting woven fabric is proposed. If the temperature inside the clothes rises during sweating, the air permeability of the knitted fabric will increase, and the woven fabric will stay in the clothes. On the other hand, if the sweating stops and the temperature inside the clothes starts to drop, the air permeability of the knitted fabric will decrease, which can suppress the cold caused by the excessive release of water, and can always maintain a comfortable feeling. the

For example, Japanese Unexamined Patent Publication No. 3-213518 proposes a woven fabric using side-by-side composite fibers in which a heteropolymer of a polyester layer and an amide layer are bonded together. Utilizing the difference in moisture absorption of heterogeneous polymers, the fiber itself is deformed at high moisture absorption to eliminate the wetness of clothes and the reduction of air permeability. However, with only side-by-side conjugate fibers, the amount of change in fiber shape at high moisture absorption is small, and this performance cannot be fully realized. Furthermore, there arises a problem that a special manufacturing facility for simultaneously spinning two kinds of polymers is required, which increases the cost. the

In addition, JP-A-10-77544 proposes a woven fabric composed of twisted yarns made of a hygroscopic polymer and made of the twisted yarns. Torsional torque is generated during moisture absorption, and the air flow rate is increased by changing the weave from a planar weave shape to a three-dimensional weave shape. However, with such a woven fabric, since the woven fabric changes greatly from a planar shape to a three-dimensional shape when moisture is absorbed, the dimension of the knitted fabric may not be stable. Furthermore, there arises a problem that the cost increases due to the need for a twisting process.

The above-mentioned woven fabric exhibits the following characteristics: when wetted with water, the porosity of the fabric increases, so the air permeability increases; when dry, the porosity of the fabric decreases, and the air permeability decreases. It is preferable that the sample number n of the yarn used for the measurement of the said average length is 5-20. the

When each of the above-mentioned two kinds of yarns (1) and (2) different in water absorption and self-extensibility is used for the following measurement of water absorption and self-extensibility, the yarn with a frame circumference of 1.125 m While applying a load of 0.88mN/dtex on the skein frame, roll each of the aforementioned silk strips to form a skein with 10 turns, remove the skein wire from the aforementioned skein frame, and heat the wire at a temperature of 20°C. Leave it in an air environment with a relative humidity of 65% to dry for 24 hours, and apply a load of 1.76mN/dtex to the dried strand when it is an inelastic wire having a breaking elongation of 200% or less , In addition, when it is an elastic thread having a breaking elongation higher than 200%, a load of 0.0088mN/dtex is applied to measure the dry thread length (Ld, mm), and the strand is heated at a temperature of 20°C After soaking in water for 5 minutes, pull it out from the water, and apply the same load as above corresponding to the elongation at break to measure the wet wire length (Lw, mm) by the following formula :

When the self-extensibility of the thread (%)=(Lw-Ld)/(Ld)×100 measures the self-extension of each thread, preferably one thread (1) in the aforementioned two kinds of thread is +5 A yarn with high water absorption and self-extensibility with an average self-extensibility of % or more, and another yarn (2) is a yarn with low water absorption and self-extensibility showing an average self-extension rate of less than +5%.

The number n of samples used for the aforementioned measurement is preferably 5-20. the

The difference (E (1)-E (2)) of the self-extensibility (E ₍₁₎ ) and (E _{( 2)} ) of the aforementioned different kinds of filaments (1) and ₍₂₎ is preferably in the range of 5 to 40%. range, more preferably in the range of 7 to 30%, and more preferably in the range of _{10 to} 30%. %, the obtained woven fabric containing two different types of filaments has insufficient porosity difference between dryness and moisture absorption, and the air permeability when moisture absorption is insufficient. Too much air permeability or too little air permeability when dry.

In the woven fabric of the present invention, the mass ratio of the yarn (1) with high water absorption and self-extensibility to the yarn (2) with low water absorption is preferably 10:90 to 70: when woven into a fabric. 30, more preferably 15:85 to 50:50, in the case of knitted fabrics, preferably 10:90 to 60:40, more preferably 20:80 to 50:50. the

In one embodiment of the woven fabric containing two different types of filaments of the present invention, it has a weaving structure, such as a circular weaving structure, and the aforementioned two kinds of filaments (1) and (2) are parallel to each other. used for thread. the

In Fig. 1 (Fig. 1(A) and Fig. 1(B)), two kinds of filaments (1) and (2) are paralleled in a dry state. At this time, the yarn (1) 1 with high water absorption and self-extensibility is paralleled with the yarn (2) 2 with low water absorption and extensibility in a mechanically stretched (drawn) state, and supplied to the knitting process. After the knitting process, if the tension applied to the dry yarn (1) 1 is removed, the yarn (1) 1 shrinks, but the yarn (2) 2 having low self-extensibility upon water absorption does not substantially shrink. In the braided structure obtained, the ratio A/B of the average length A of the yarn (1) 1 to the average length B of the yarn (2) 2 is controlled below 0.9, so the long yarn (2) 2 of the supplementary wire is in the In the state of being wound around the filament (1) 1, the apparent thickness of the doubling increases. In this case, the area ratio of the voids 3 to the total surface area of the woven fabric, that is, the porosity is relatively low. If the dry knitted fabric shown in Fig. 1(A) is in a state of absorbing water and being wet, then as shown in Fig. 1(B), the thread (1) 1 absorbs water and self-elongates, and the thread (2) 2 also expands accordingly. In a roughly tense state, the apparent thickness of the yarn becomes smaller, and the porosity of the water-absorbing wet fabric of FIG. 1(B) is also larger than that of the dry fabric of FIG. 1(A), improving air permeability. the

In another embodiment of the woven fabric containing two different kinds of threads of the present invention, it has a woven structure, such as a plain weave, and each of its warp and weft is composed of a thread (1) with high water absorption and self-extensibility. 1 and its low filaments (2) 2 are formed in parallel. When such doubling is woven as warp and weft, the yarn (1) with high water absorption and self-extensibility is stretched (drawn) by applying mechanical tension in a dry state, and is doubled to a dry state The filament (2) 2 is provided to the weaving process. After the weaving process is completed, if the aforementioned tension is removed, the thread (1) 1 shrinks mechanically, but the thread (2) 2 does not actually shrink. In the weaving structure obtained, the ratio A/B of the average length A of the filament (1) 1 to the average length B of the filament (2) 2 is controlled below 0.9, so as shown in Figure 2 (A), the supplementary wire The long thread (2) 2 is crimped around the short thread (1) 1, and the apparent thickness of the parallel thread increases. Therefore, the porosity in the obtained woven fabric in a dry state is relatively low. If the woven fabric is wetted by water absorption, as shown in Fig. 2(B), the thread (1) 1 absorbs water and self-extends, and the thread (2) 2 is also in a roughly tense state along with it, so the wetting of the fabric The porosity is also higher than that of the dry fabric, improving air permeability. The weaving method and knitting method using the doubling of the yarn (1)/yarn (2) used for the knitted fabric shown in FIGS. 1 and 2 will be described later. the

In the woven fabric containing two different types of filaments of the present invention, the porosity in the dry state and the wet state and the change rate of the porosity of the fabric due to the change from the dry state to the wet state can be obtained by the following measuring method . the

Soak in water for 5 minutes, pull out from the water, clamp between a pair of filter papers, apply a pressure of 490N/ ^m2 for one minute, remove the water existing between the fibers in the sample, and prepare multiple wet samples. Each of the aforementioned dry sample and wet sample was observed with an optical microscope at a magnification of 20 times to obtain the porosity obtained by the following formula:

Porosity (%) = (the total area of the voids between the filaments) / (observation area) × 100 The average value, according to the following formula:

Void change rate (%) = [(average void ratio of wet sample) - (average void ratio of dry sample

Average porosity)]/(average porosity of the dry sample)×100 From the average porosity of the above-mentioned wet sample and the average porosity of the dry sample, calculate the porosity change rate. Preferably, the number n of the measurement samples is 5-20. the
