軽量な素材の開発が望まれている。BACKGROUND OF THE INVENTION In recent years, fashion and casual wear have become widespread in the field of winter sports clothing such as ski wear. For this reason, in addition to hygienic and functional comfort such as moisture permeability and waterproofness, there is a strong demand for functional comfort such as comfort that does not interfere with the wearer's exercise and activities, and there is a need to develop even lighter materials. desired.

ともに，染色が困難であるという欠点をも有している。[0003]Currently, materials for winter sports clothing include:
The majority are made of nylon and polyester, which are relatively lightweight and have good yarn strength. However, since the density of nylon used in clothing is 1.14 g/cm3 and the density of polyester is 1.38 g/cm3, there is a limit to reducing the weight while maintaining a certain level of fabric strength. Lightweight fabrics using hollow fibers of polyester or nylon have also been proposed, but the strength of the hollow fibers is insufficient and they have not been put into practical use. On the other hand, polypropylene fiber has a density of 0.91 g/cm3, which is the lightest of all fibers, and has good yarn strength, making it an optimal material for weight reduction. It also has the disadvantage that it is difficult to dye.

般衣料にも応用されていないのが現状である。[0004] Therefore, in order to take advantage of the light weight of polypropylene as a fiber material for the base fabric and improve its dyeability, a concentric composite fiber with polypropylene as a core component and nylon as a sheath component was developed in JP-A-Sho. 61-8331
Although it was proposed in Publication No. 4, both were prone to peeling and had problems with stretching operability. Also, JP-A-60-813
Publication No. 16 also proposes a core-sheath type composite fiber in which the core component is polypropylene and the sheath component is a mixture of polypropylene and nylon, but in this case, since the mixture is used as the sheath component, There was a practical problem in that the mixed spots turned into dyed spots as they were. Currently, polypropylene fibers and polypropylene/nylon composite fibers have not been applied to general clothing, let alone sports clothing that requires moisture-permeable and waterproof functionality.

The purpose is to obtain a moisture-permeable waterproof fabric having equivalent dyeability, moisture permeability, water resistance, and tensile strength.

A synthetic polymer mainly composed of polyurethane resin or polyamino acid urethane is applied onto a fabric mainly composed of a core-sheath composite fiber with a density of 1.01 g/cm3 or less, which has a 90 to 30/70 mixture as a core component and nylon as a sheath component. The gist of this invention is a moisture-permeable and waterproof lightweight fabric characterized by having a moisture-permeable and waterproof membrane made of a synthetic polymer mainly composed of resin.

In the present invention, "nylon" means nylon 6 (polycapramide), nylon 66 (polyhexamethylene adipamide), or polyamide containing these as main components. The nylon used in the present invention is one that has a relative viscosity (measured using 96% sulfuric acid as a solvent at a concentration of 1 g/deciliter and a temperature of 25°C) of about 2.0 to 3.5, which is usually used in the production of clothing fibers. is used.

用いられる。[0008] Polypropylene (hereinafter referred to as PP) is isotactic PP whose melt flow rate (MF value) conforms to ASTM D-1238 (L).
Those with a value of less than 20 g/10 minutes as measured by the method described above are preferably used.

A problem arises in that it cannot be completely covered.

。[0010] The mixing weight ratio of nylon and PP in the core component must be 10/90 to 30/70. If the mixing weight ratio is smaller than this range, the core component and sheath component will easily separate, causing operational problems; if it is larger, on the other hand, the proportion of PP in the composite fiber will decrease, making it difficult to achieve the desired low It is not possible to obtain composite fibers with high density.

The ratio is selected so as to obtain a fiber in which the core component is completely covered by the sheath component, and is usually 50/50 to 80/20. If the proportion of the core component is too small, the desired weight reduction will not be achieved, and if it is too large, a portion of the core component will be exposed on the fiber surface.
This may cause problems with operability or staining spots.

ブルが発生する。The core-sheath composite fiber of the present invention can be produced by a conventional method for producing a core-sheath type composite fiber, but in order to produce it with good productivity, it is preferable to employ high-speed spinning and drawing methods. That is, the melt spun yarn is 3,500 to 5,500 m/
This is a method in which the film is wound up at a speed of 100 to 200°C and then stretched 1.2 to 2.2 times in a temperature range of 100 to 200°C. On this occasion,
It is necessary to keep the spinning winding tension below 0.5 g/d; if the tension is high, the shrinkage stress of PP cannot be alleviated, and the
If the yarn tube is wound more than g, there will be a problem that the yarn tube will not come out from the winder.

Normal nylon fibers with a low glass transition temperature can be drawn without applying any particular heat, but the fibers of the present invention contain PP in the core component, so the core component cannot be drawn unless heat is applied. The stretching of the sheath component does not occur uniformly, resulting in poor stretching operability and at the same time, yarn unevenness occurs, causing uneven dyeing. Therefore, the stretching temperature must be 100°C or higher, and the upper limit is 200°C due to the relationship with the melting point of nylon.
℃. On the other hand, the drawing ratio is related to the spinning speed and the strength and elongation characteristics of the target fiber, but the elongation is 20 to 80%.
In order to produce fibers with good drawing operability, the above spinning speed should be in the range of 1.2 to 2.2 times.

When core-sheath composite fibers of cm3 or less are used, the nylon sheath component located on the outer surface of the fibers is dyed in the same way as the nylon of conventional nylon fabrics, and the low density of the PP component contributes to the weight reduction of the fabric. On the other hand, the moisture-permeable waterproof property of the fabric is maintained by the moisture-permeable waterproof membrane on the surface of the fabric, and thus,
This is a moisture-permeable waterproof fabric that is lighter than conventional moisture-permeable waterproof nylon fabrics and moisture-permeable waterproof polyester fabrics, and has the same dyeability as conventional nylon fabrics.
