Problems solved by technology

According to this method, a low water retention rate can be obtained, but in the case of long-term immersion in water, the waterproof performance is lower than that of a fluorine-based water repellent agent containing PFOA having 8 or more carbon atoms.

Embodiment 1

[0158] Yarn A is used for the warp yarn, yarn B is used for the weft yarn, and yarn C is used for the weft yarn. figure 1 The stretch fabric 1 shown alternately repeats plain weave portions 2 with double weft portions 3 . In the obtained fabric, nylon contained 66% by mass and polyurethane contained 34% by mass. The fabric is refined, intermediately fixed, dyed, and dried according to conventional methods. The obtained fabric was dipped in the following waterproof formulation, wrung out at 50% with a pickup, and then dried in a pin tenter set at a temperature of 130°C. Next, dry heat treatment was performed for 1 minute in a pin tenter set at a temperature of 170° C. to obtain a processed fabric of Example 1. The resulting processed cloth exhibited a high degree of water repellency, and a fabric cloth having a low water retention rate and exhibiting excellent water repellency was obtained.

Embodiment 2

[0167] Use yarn D for the warp and yarn E for the weft to make a plain weave fabric. Weaving nylon is 70%, polyurethane is the fabric of 30%, implements dyeing process and water-repellent process similarly to embodiment 1, and making warp density is 205 / 2.54cm, and weft density is 200 / 2.54cm, and per unit area The mass is 95g / m 2 fabric. The obtained processed fabric has high stretchability, good adhesion to human skin, high water repellency, and low water retention and excellent water repellency. The results are summarized in Table 1.

Embodiment 3

[0180]Use the fabric cloth of embodiment 1 and the fabric cloth of embodiment 2 to sew Figure 7 Men's swimsuits are shown for swimming competitions. The fabric cloth of Example 1 is a fabric in which the plain weave portion and the double weft portion are alternately repeated in the striped portion 24, and the striped portion 24 is arranged in the height direction of the human body. The plain weave fabric cloth of Example 2 is the plane portion 25 .

Abstract

A swim suit 23 which comprises a polyurethane elastic yarn, and which is configured such that: the polyurethane elastic yarn contains 0.5-10% by mass of a cationic high molecular weight compound A that has a number average molecular weight of 2,000 or more, while containing an inorganic chlorine deterioration inhibitor B; the (cationic high molecular weight compound A) / (inorganic chlorine deterioration inhibitor B) mass ratio is within the range of 0.3-3; the polyurethane elastic yarn is provided with a silicone-based oil; and the swim suit fabric has been subjected to a water repellent treatment. It is preferable that the swim suit 23 contains a polyurethane elastic yarn that has a fluorine (F) / carbon (C) ratio of 0.030 or more in the elemental mass concentration on the polyurethane elastic yarn as determined by scanning electron microscope-energy dispersive X-ray spectroscopy (SEM-EDX). Consequently, the present invention provides a swim suit which has high water repellency, low water absorptiveness and high buoyancy.

Description

technical field [0001] The present invention relates to a swimsuit comprising polyurethane elastic yarn which is highly water-repellent and hardly wetted when immersed in water, and which can maintain a low water retention rate for a long time. Background technique [0002] In order to impart water repellency and oil repellency to clothing and industrial materials made of fiber products, water and oil repellents made of fluorine-based compounds have been widely used conventionally. [0003] However, it is clear that the above-mentioned fluorine-based water and oil repellents contain compounds that may affect the living environment and organisms, such as perfluorooctanoic acid (hereinafter referred to as PFOA), perfluorooctane sulfonic acid (hereinafter referred to as PFOS), etc., so it is desirable There are fiber products using fluorine-based water and oil repellents that do not contain the above-mentioned compounds. [0004] PFOA is mixed into the water repellent as a tra...
