BACKGROUND OF THE INVENTION
The present invention is characterized by comprising a knitted fabric including a covering yarn using polyurethane elastic yarn as a core yarn and a hygroscopic crosslinked acrylic fiber, and has excellent support power and less moisture and stickiness and excellent hygroscopicity. Comfortable pantyhose or tights.
[0002]
[Prior art]
As women's living environment is heated indoors, not only in summer but also in winter, there are many diffuses of sweat and insensitive vapors from the body, and the clothes become moist due to increased humidity. You can see inside.
In particular, leg knits such as pantyhose and tights do not change much indoors and outdoors, and touch the skin directly, and are greatly affected by sweat and insensitive excretion from the body.
However, leg knits such as conventional pantyhose and tights increase the degree of adhesion to the skin due to improved support, and the moisture in the clothes also increases due to sweat and insensitive vaporization from the body, causing a feeling of tingling and stickiness Etc. In particular, when wearing a leg knit with poor hygroscopicity, the pantyhose in the summer is covered with the panties, and the winter tights are thick. It tends to cause discomfort such as feeling.
As water-absorbing fibers, natural fibers of cotton and wool, rayon of regenerated fibers, acetate of semi-synthetic fibers, and the like are used. However, although these fibers are excellent in water uptake speed and water retention, they do not satisfy the function of adjusting the humidity in clothes because of their poor moisture absorption rate. Furthermore, it has not yet achieved satisfactory performance (feel, durability, etc.) as a leg knit that satisfies the above functions and is always worn by women in close contact with the skin.
[0003]

[0010]
The present invention is described in detail below. The hygroscopic crosslinked acrylic fiber in the present invention is disclosed in JP-A- 9-59872, and refers to a fiber having a saturated moisture absorption rate of 15 to 35% at 20 ° C. and 65% RH. Further, the blended spun yarn containing the hygroscopic crosslinked acrylic fiber is a blended spun yarn composed of 10 to 70% by weight of the hygroscopic crosslinked acrylic fiber, general natural fiber and chemical fiber, and 90 to 30% synthetic fiber. It can be achieved by using it. The blending ratio for obtaining a spun yarn of hygroscopic crosslinked acrylic fiber, general natural fiber, chemical fiber, and synthetic fiber is preferably 30% by weight or more and 50% by weight or less. If it is 20% by weight or more, it reaches or exceeds the saturated moisture absorption rate at 20 ° C. and 65% RH of general natural fibers. On the other hand, if it is 50% by weight or more, the workability in the spinning process will be hindered and the quality of the spun yarn will be lowered, or the productivity will be sacrificed extremely. Furthermore, in order to achieve the function and quality of the yarn in a well-balanced manner, the blending rate of the mixed spun yarn of hygroscopic crosslinked acrylic fiber, general natural fiber, chemical fiber, and synthetic fiber is preferably 30 to 40% by weight. The hygroscopic crosslinked acrylic fiber herein has a saturated moisture absorption rate of 15 to 35% by weight at 20 ° C. and 65% RH, and a moisture absorption rate constant k1 of the following rate equation is 0.015 to 0.029. And a moisture-absorbing cross-linked acrylic fiber characterized by having a temperature control / humidity control function in which the moisture release rate constant k2 is in the range of 0.005 to 0.015. Examples of general natural fibers to be used include wool, animal hair, cotton, hemp, and silk, chemical fibers include rayon, cupra, and polynosic, and synthetic fibers include acrylic, polyamide, and polyester fibers.
<Speed equation> ○ W1 = We (1-e-klt)
W1: Moisture absorption rate from time to time t dry: We: 20 ° C 65% RH saturated moisture absorption rate k1: Moisture absorption rate constant t: 0 to 30 minutes ○ W2 = (Wa-Wb) (1-e-k2t)
W2: Moisture absorption at time t from Wb Wa: 20 ° C 30% RH saturated moisture absorption Wb: 20 ° C 80% RH saturated moisture absorption k2: Moisture absorption rate constant t: 0 to 30 minutes Improvement in discomfort such as a feeling of cooling is achieved by the hygroscopic crosslinked acrylic fiber itself having these functions, and by optimizing the blend ratio of general natural fibers, chemical fibers and synthetic fibers. In addition, in order to enhance the basic properties of leg knit products, such as stretchability, touch, and durability, a single-layer yarn is made of polyurethane elastic yarn as the core yarn and a mixed spun yarn of hygroscopic crosslinked acrylic fiber. This can be achieved by using a covering yarn or a double covering yarn. In order to further improve the durability (strength), it is more preferable that the mixed spun yarn of the hygroscopic crosslinked acrylic fiber is twisted with the nylon filament yarn. In addition, blended spun yarn of hygroscopic cross-linked acrylic fiber and nylon filament yarn are twisted together, so that mixed spun yarn of hygroscopic cross-linked acrylic fiber is active in sweating and insensitive excretion during sweating (wet). Absorbs and removes the stickiness of nylon and keeps the skin dry. More preferably, when the lower yarn of the double covering yarn is made of a mixed spun yarn of hygroscopic crosslinked acrylic fiber and the upper yarn is made of a nylon filament yarn, sweat or insensitive excretion during sweating (when wet) is achieved. By the capillary phenomenon, it passes through the nylon filament yarn on the surface and is actively absorbed by the mixed spun yarn of the hygroscopic crosslinked acrylic fiber, so that the skin surface can be kept still lighter. Next, with regard to knitting / workability of pantyhose, if a mixed spun yarn of moisture-absorbing crosslinked acrylic fiber is used alone at the time of segregation, tearing or the like occurs in knitting, and the operability deteriorates due to the stop. Therefore, the blended spun yarn of hygroscopic crosslinked acrylic fiber is not used alone, but it is made of a twisted yarn with a nylon filament yarn and a wound yarn of a covering yarn to prevent tearing during knitting and knitting pantyhose・ Processability (operability) can be improved. The polyurethane elastic yarn of the core yarn used here has a bond of -NHCO- in which R-OH and R'-NCO are polyaddition-reacted in the polymer regardless of dry, wet, and melt spinning methods. In this, an ether type having an ether bond and an ester type having an ester bond are shown.
