Description
Technical field
The present invention relates to a kind of braiding cloth and silk of two variety classes strands and clothes that comprises this braiding cloth and silk of containing.If narration in more detail, then the present invention relates to a kind of because the absorption of moisture, the voidage of cloth and silk tissue increases and the gas permeability raising, because dry, the voidage of cloth and silk tissue reduces and braiding cloth and silk that contains two variety classes strands that gas permeability reduces and the clothes that comprises this braiding cloth and silk.
The braiding cloth and silk that contains two variety classes strands of the present invention can prevent to bedew clothes because of perspiration when wearing and gas permeability reduces the unplessantness displeasure that produces.
Background technology
In the past, followed the purposes of when wearing, perspiring, and, then produced and follow because the adhesional wetting of sweat and gas permeability reduce the problem of the unplessantness displeasure that produces if as for example use such as sportswear or underwear by the braiding cloth and silk that synthetic fiber or natural fabric etc. constitute.
As eliminating as like this because the means of the unplessantness displeasure of perspiration generation, a kind of gas permeability self-regulated nodal pattern woven cloth silks is proposed, if the temperature when perspiring in the clothes raises, then the gas permeability of braided fabric improves, and emits, on the other hand with making the water effective of being detained in clothes, the temperature that stops in the clothes if perspire begins to reduce, then the gas permeability of braided fabric reduces, and suppresses because the cold air of excessively emitting generation of moisture can keep comfortable sensation always.
For example, open a kind of braiding cloth and silk of proposition in the flat 3-213518 communique, the composite fibre of type side by side that its use is fitted the heteropolymerization thing of polyester layer and amide layer the spy.Utilize the moisture absorption of heteropolymerization thing poor, when high moisture absorption, make the fiber itself distortion, eliminate the adhesional wetting of clothes and the reduction of gas permeability.But, only use type composite fibre side by side, the variable quantity of the fiber shape when high moisture absorption is little, can not find this performance fully.And then generation need be used for the special manufacturing equipment that 2 kinds of polymer are spinned simultaneously and problem that cost is increased.
Again, open in the flat 10-77544 communique, propose a kind of strand enforcement twisting, with the braiding cloth and silk of this hygroscopicity twisting strand formation forming by hygroscopic polymer the spy.The torque that twists when moisture absorption becomes the three-dimensional shape of organizing by making braided fabric from the change of shape of organizing on plane, increases Air permenbility.But with such braiding cloth and silk, the braiding cloth and silk is owing to big variation takes place from the flat shape to the three-dimensional shape, so the size potentially unstable of braided fabric when moisture absorption.And then, produce owing to being necessary to carry out the problem that twisting process increases cost.
Summary of the invention
The object of the present invention is to provide a kind of because moisture absorption, the voidage of braiding cloth and silk increases and the gas permeability raising, when drying, the voidage of braiding cloth and silk reduces and the gas permeability reduction, but changes little braiding cloth and silk that contains two variety classes strands and the clothes that comprises it on the size shape of braiding cloth and silk.
Inventors of the present invention are for reaching the result that above-mentioned purpose continues wholwe-hearted research, discovery absorbs water in use, 2 kinds of different mutually on extensibility strands braidings are made when weaving cloth and silks, poor by on aforementioned two variety classes strands, specific benefit silk being set, make the braiding cloth and silk that obtains owing to the variation of suction with the size of drying diminishes, but because suction (moisture absorption) can increase the voidage of braiding cloth and silk, gas permeability is improved, and when drying, can reduce the voidage of braiding cloth and silk, gas permeability is reduced, finish the present invention based on this opinion.
The braiding cloth and silk that contains two variety classes strands of the present invention is to comprise suction, from extensibility high monofilament strand and suction, braiding cloth and silk from the low strand of extensibility, wherein: aforementioned suction, from the high strand of extensibility is suction, from the high monofilament strand of extensibility, making aforementioned braiding cloth and silk is that 20 ℃ of relative humidity are size stabilization in 65% the atmosphere gas having temperature, and be that 30cm and parallel or horizontal direction are in the test film taked of the size of 30cm with warp or longitudinal direction, aforementioned suction, from extensibility high monofilament strand and suction, the strand low from extensibility satisfies the necessary condition of representing with following formula
A/B≤0.9 (1)
[in the formula (1), A represents the aforementioned suction taked from aforementioned woven cloth silks test film, average length from the high monofilament strand of extensibility, B represents to take from aforementioned woven cloth silks test film, and with aforementioned suction, suction from the identical direction configuration of the high monofilament strand of extensibility, average length from the low strand of extensibility, when the length of aforementioned each strand is the non-resilient strand of the elongation at break of expression below 200% at this strand, determined under the loading of 1.76mN/dtex, when this strand is the elasticity strand of expression high elongation at break than 200%, determined under the loading of 0.0088mN/dtex]
And aforementioned braiding cloth and silk satisfies following important document 1 or 2 or 3 or 4,
Important document 1: aforementioned braiding cloth and silk has the tissue of weaving into, and with aforementioned suction, from the high monofilament strand of extensibility and aforementioned suction, from the low strand doubling of extensibility, forms compound wire loop in the tissue aforementioned weaving into,
