Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to comfortable pajamas with excellent hygienic and comfort functions.

Traditionally, pajamas have not been comfortable to wear unless they have excellent hygienic and comfort functions, leading to increased discomfort. However, the conventional PAV design is hygienic 4I like Jin.
style, color, and comfort without pursuing functionality.
The materials used, structure, and shape were determined empirically and conceptually, centering on the pattern, and were manufactured.As a result, it was impossible to obtain a pave that was both hygienic and comfortable to wear.

In order to solve these problems, the present inventors conducted a wear test using various types of pajamas.The pajamas are hygienic and comfortable to wear (comfortable), and they are soft and comfortable to the touch. Find something that is refreshing,
Furthermore, when we investigated the relationship between these and physical property values, we found that the hygienic and comfortable Kupa V-Yama has frictional properties.

Physical property values such as bending deformation characteristics, compressibility, and 1jta properties make a large contribution, and the friction coefficient 1 bending deformation gradient is small.
We have found a material that has high compressibility, good silver absorption, and good properties when left unused, and has good comfort and excellent hygienic functionality.

In other words, the pajamas of the present application are made of a two-layer knitted fabric in which the surface layer absorbs silver and water to an appropriate degree, and the second surface layer or middle layer retains water with an even higher ability, while sufficient silver release is performed from the surface layer. The surface knitted fabric weight is 80-12017d,
The knitted fabric weight on the back side is 110 to 14017 d, which is denser than that on the front side.

The two-layer knitted fabric has a JISL-1018 (initial load 1f/

The eel release rate 30 minutes after the transition is 1.5 times or more than the recording rate 30 minutes later, and the surface friction 1 coefficient (under a load of 10 f) is 0 on average in the vertical and horizontal directions. It satisfies the requirements of .8 to 1.1, and the knitted fabric as a whole needs to be easy to bend and one surface to be slippery.

The compression rate 1 bending deformation gradient, suction/release rate, and surface friction coefficient are determined by K as follows.

(1971)) The two-layer knitted fabric that composes the pajamas of the present application and satisfies the above requirements is the type of yarn that makes up the knitted fabric, yarn material and texture such as blending rate, cross-knitting rate, and basis weight. This can be obtained by appropriately selecting the knitted fabric structure of K. The knitted fabric used in the pajamas of the present application is a blended yarn of cotton and nylon or ester as the yarn forming one surface (the blend ratio is cotton: nylon or ester: 25%, 75% to 75%! 25%).
) and using cotton yarn as the yarn forming the back side, a two-layer knitted fabric knitted into a plain knitted purple knitted fabric is preferred. In this case, the thickness of the blended yarn forming one surface is 30 mm.
/I/1 to 60"/1 is preferable, and the thickness of the cotton yarn forming the back surface is preferably *40"/l to To"/1. The i91 knitted fabric weight on the front surface is 80 to 1201/d- 1fi, preferably 110 to 140 f/d on the back side, and it is preferable to make the knitted fabric weight on the back side denser than that on the front side.・Such knitted fabrics are suitable for the back side to absorb and absorb water properly. The above-mentioned compression ratio 1 bending deformation gradient of the present invention has the above-mentioned ability to sufficiently KPM from the surface while retaining water on the surface or the intermediate layer, and is characterized in that the entire knitted fabric is bendable and the surface is slippery.

Pajamas made of the knitted fabric satisfy all of the ll1jIl rate, moisture release rate, and surface friction coefficient, and are soft) @.

The feeling of smoothness increases, and the feeling of weight and thickness decreases, making it feel soft and dry.
It feels good on the skin and has excellent hygienic functions. For example, before going to bed (room temperature 12~
24℃, 111 degrees 67-7811RH) upon waking up (room temperature 1
Pajamas that satisfy all the requirements of the present invention and conventional pajamas were worn alternately overnight under environmental conditions of 0 to 15.5 degrees Celsius, M degrees 71 to 82'11 RH), and the subjective feeling of wearing was evaluated. The evaluation was performed using the SD method (Semantic D (ffe
