Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a method for producing a double-woven fabric having high humidity and water repellency.

(Prior art) Conventionally, water-repellent fabrics have been known, such as high-density fabrics treated with water-repellent treatment.However, since these fabrics were high-density fabrics, even though they were water-repellent, they were not breathable. The texture was poor and the texture was paper-like. For this reason, when wearing such conventional woven clothing for sports or work in hot and humid climate conditions such as during the rainy season, the wearer feels stuffy, uncomfortable, and uncomfortable.

(Problems to be Solved by the Invention) An object of the present invention is to obtain a fabric with excellent moisture permeability and water repellency that is suitable for outdoor sportswear such as golf, blazers, jumpers, and the like.

(Means for Solving the Problems) The present invention provides synthetic fiber yarns having hydrophobic properties in the front warp and/or counter weft, and spun yarns having hydrophilic properties in the back warp and/or back weft. This is a method for producing a double-woven fabric having moisture permeability and water repellency, in which a double-woven fabric is woven into a double-woven fabric, which is then subjected to a blinding process and, if necessary, a water-repellent finish.

The hydrophobic fiber yarns arranged in the front warp and front weft are defined by the official moisture content (JISL-
1096) is less than 5%, and hydrophilic fibers refer to fiber yarns having a difference in official moisture content of 1% or more. Examples include polyester fiber yarn, acrylic fiber yarn, polyamide fiber yarn, vinyl chloride fiber yarn, and the like. In this case, it may be a filament yarn, a stable fiber yarn, or a mixed fiber yarn. The thickness of chain thread is 67 denier ~ 177 denier (80'S ~ 30
'S) is preferred, more preferably 89 denier to 13 denier
3 denier (60'S to 40'S). The chain yarn may be treated to be water repellent.

The hydrophilic fiber yarns arranged in the back warp and back weft refer to the official moisture content (Jrs L
-1096) is 5% or more fibers, such as cotton, linen,
This includes natural fibers such as wool, and recycled fibers such as viscose and rayon. The thickness of the chain thread is 67 denier ~ 1
77 denier (so's to 30'S) is preferred, and 89 denier to 133 denier (60'S) is more preferred.
~40'S).

The reason for arranging hydrophobic fiber threads on the front surface and hydrophilic fiber threads on the back surface is that hydrophobic fibers have a better water repellent effect in rainy weather, and the part that comes into contact with the skin (back surface) is made of hydrophilic fibers. This is because it has better sweat absorption properties, and has the effect of being released through the surface as steam generated by body heat.

The weave structure of double group 1 may be any weave structure such as Bedford Hood, Big, Matelasse, tricot weave, and wind weave. When the surface cover factor is plain weave, the weave density is 20 to 40. Preferably 25-35, 25-45 for twill, preferably 30-40, 30-40 for satin.
A relatively high density of 50, preferably 35 to 45 is preferable because it has excellent water repellency. The cover factor on the back is
10-30 for plain weave, preferably 15-25, and 20-40 for twill. Preferably 25-35, 25 in case of satin
~45, preferably 30~4o, which may be a rough density compared to the surface weave density.

In addition, a double warp weave or a double weft weave may be used, but in this case as well, it is necessary to arrange hydrophobic fibers on the front surface and hydrophilic fibers on the back surface.

The reason for the double weave is that the surface has a hydrophobic and water-repellent effect, and the back side has a textured effect to obtain a sweat-absorbing effect. The gray fabric is subjected to a blinding process and a water repellent process. The water-repellent finish may be performed simultaneously with the blinding process, or may be performed after the blinding process. The blinding process is carried out using a high-pressure calender-type processing machine, and the pressure is 30 to 80T/-, preferably 40 to 70T.
O! 1/- is good.

Although the temperature varies depending on the fiber, a relatively low temperature of 50° C. to 180° C., preferably 80° C. to 130° C., will prevent the texture from becoming paper-like. Water repellent treatment is usually carried out using a silicone water repellent, a fluorine water repellent, a paraffin water repellent, etc.

(Actual example) A mixed yarn of 50'S of 50% polyester fiber staples and 50% polyester fiber filaments is arranged as the front warp and front weft, and the warp density is 135/inch, til.
Woven on 3/1 twill with 55% polynosic fiber and 4% cotton as back warp and back weft.
A gray fabric was obtained by weaving a double weave with a front fill and a back plain weave by arranging SO's blended yarn with 5% and arranging it in a plain weave with a warp density of 75 yarns/inch and a weft yarn density of 60 yarns/inch. . Pressure cuff 0 tons/-1 temperature 1 is applied to the gray fabric by simili calendering.
A blinding process was performed at 00°C. Afterwards, a dyeing process was carried out that included a silicone water repellent treatment. The obtained fabric was water-repellent, sweat-absorbent, and did not feel stuffy. Golf wear was made with the front side of the fabric as the front side and the back side as the back side. This golf wear has hydrophilic fiber yarn arranged on the desk side, so it has a sweat-absorbing effect, and the moisture is released as water vapor on the surface, so there is less stuffy feeling.
It was comfortable and comfortable to wear even during the rainy season when it is rainy and humid. The fabric has a water resistance rating of 56.
0m water column and moisture permeability is 6100 Kt/rr? /
It was 24 hr, X.

In addition, water resistance was measured by JISL-1092 method, and moisture permeability was measured by JIS Z 0208 method.

Comparative example Polyester filament 75 denier/144 filament for warp and warp total cover factor - 2035
(Warp density: 137 threads/inch, weft density: 98 threads/inch) A plain weave was woven and treated with blinds and a water-repellent finish. The fabric has a water resistance of 420B water column and a moisture permeability of s 100 g? /n? / 24hrs. The fabric had a sticky feel to the touch and felt stuffy, making it uncomfortable to wear.

(Effects of the Invention) The woven fabric obtained by the method of the present invention is both water repellent and moisture permeable (hygroscopic and moisture releasing), so it does not feel stuffy, and is not paper-like, so it is a woven fabric that feels good to the touch.
