Description

  The present invention relates to a fabric. Specifically, the present invention relates to a fabric provided with a resin.

  Conventionally, since it has excellent strength and has a large production volume, it has high versatility, and polyester fibers have been used in various fields. Polyester fibers are fibers that are difficult to dye due to high molecular crystallinity and a dense structure. For this reason, disperse dyes are used for dyeing polyester fibers. Disperse dyes are colored by dye molecules diffusing into the fiber from the gaps in the amorphous part of the fiber.

  Thus, the disperse dye is not chemically bonded to the polyester resin. For this reason, when a resin is applied to a cloth made of polyester fibers colored with a disperse dye (hereinafter, sometimes referred to as a polyester fiber cloth) by, for example, texture processing, coating, printing, etc., the disperse dye is applied to the resin. Therefore, the disperse dye is transferred from the fabric to the resin layer, and so-called dye transfer sublimation causes problems such as dye bleeding, a decrease in heat resistance, and a decrease in friction fastness.

  As a method of suppressing the dye migration of the resin processed product of the polyester fiber fabric, Patent Document 1 discloses a method of treating a surface of the polyester fiber material with a water-repellent resin such as a fluorine resin or a silane resin as a barrier layer. It is disclosed. However, the texture becomes coarse and the seating feeling is deteriorated, and a sufficient dye transfer suppression effect for a vehicle is not obtained. Patent Document 2 discloses a method for performing ozone treatment as a method for modifying the surface of a polyester fiber material. However, the dye transfer suppression effect sufficient for vehicle use is not obtained. Further, Patent Document 3 discloses a method in which microporous inorganic fine particles are contained as a substance for adsorbing disperse dyes in a coating resin. However, since the texture becomes coarse and the color becomes white, it becomes difficult to reproduce a desired color, and a sufficient dye transfer suppression effect for a vehicle application is not obtained.

  On the other hand, Patent Document 4 discloses a method of knitting a surface in contact with a resin layer with polyester fibers dyed with a cationic dye. However, since the yarn is weak against heat and becomes brittle, there is a problem that the heat resistance is not sufficient for vehicle use.

Japanese Patent Laid-Open No. 4-174767 JP-A-5-287673 JP-A-2-251672 JP 2014-29050 A

  The present invention has been made in view of such a current situation, and even a fabric in which a resin is applied to a fabric made of polyester fiber can suppress dye transfer to the resin, An object of the present invention is to provide a fabric excellent in friction fastness.

  The original polyester fiber is colored in a state in which a colored pigment (pigment particle) that is insoluble in water, oil, alcohol or the like and has a particle size much larger than that of the dye is dispersed inside the fiber. The original polyester fiber is deep and dark, and has problems such as discoloration, contamination and color transfer due to washing and friction, discoloration due to sunlight, and dye transfer due to heat, etc. It is difficult to compare with polyester fibers dyed with disperse dyes having a small particle size. In this embodiment, the fiber which comprises the part which contacts the resin of a fabric at least is comprised by the original polyester fiber. Thereby, even if resin is given to cloth, it can control that a color pigment transfers to resin.

A woven fabric scrim (167 dtex polyester processed yarn) was inserted into this dispersion to make a paper sheet, and then entangled by a columnar flow treatment and then dried at 130 ° C. and buffed to prepare a nonwoven fabric.

The obtained non-woven fabric was impregnated into a resin solution prepared according to the following prescription 4, treated with mangles so that the resin coating amount after drying was 45 g / m ² , and then dried at 130 ° C. for 10 minutes with a heat setter. . Thereafter, buffing was performed with an emery raising machine, and heat treatment was performed at 130 ° C. for 2 minutes with a heat setter to obtain a nonwoven fabric of Reference Example 4 .
The obtained nonwoven fabric had a heat resistance of fading 4-5 grade, and a fastness to friction was a dry cloth grade 3-4, and an artificial acidic sweat liquid soaked cloth grade 3.

The present invention is a fabric to which a resin is applied, wherein at least a portion of the fiber that contacts the resin is an original polyester fiber, and the resin is not applied to the back surface of the fabric, and the fabric has a front. It is a fabric that is partially applied to the surface.

The present invention is a fabric to which a resin is applied, wherein at least a portion of the fiber that contacts the resin is an original polyester fiber, and the resin is not applied to the back surface of the fabric, and the fabric has a front. The cloth is partially applied to the surface and the resin is exposed on the outermost surface of the cloth.

The present invention is a fabric to which a resin is applied, wherein the fabric is a knitted fabric, and fibers constituting at least a portion in contact with the resin are original polyester fibers, and the resin is disposed on the back surface of the fabric. It is a fabric that is not applied, is partially applied to the front side of the fabric, and the resin is exposed on the outermost surface of the fabric.

Claims (5)
