Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of textile material, more specifically, especially relate to a silk protein modified polyester cotton fabric. BACKGROUND

[0002] The polyester cotton fabric is made of polyester fiber and cotton fiber, and has the advantages of polyester, such as stiffness, wrinkle resistance, easy washing and quick drying, and the softness, comfort, moisture absorption and ventilation of cotton fiber, and is widely used in clothing, home textiles and other fields. However, with the increasing demand of consumers for the performance of textiles, the traditional polyester cotton fabric still has some deficiencies in some aspects.

[0003] Based on the above, the skin-friendly property needs to be improved compared with natural fiber fabric, and long-term contact with the skin may cause discomfort; although the moisture absorption is better than that of pure polyester fabric, it is still difficult to quickly remove sweat after high humidity or intense exercise, resulting in a hot feeling for the wearer; and the ultraviolet resistance is limited, which cannot provide sufficient sun protection for the human body. INVENTION CONTENTS

[0004] In order to solve the above technical problems, the utility model provides a silk protein modified polyester cotton fabric to solve the problems of causing discomfort, hot feeling and limited ultraviolet resistance in the above background technology.

[0005] The purpose and effect of the silk protein modified polyester cotton fabric of the utility model are achieved by the following specific technical means:

[0006] A silk protein modified polyester cotton fabric, comprising a polyester cotton fabric, the polyester cotton fabric is woven by plain weaving technology and made of polyester fiber and cotton fiber; characterized in that the modified raw material of the polyester cotton fabric is silk protein, which is adsorbed and attached in the polyester cotton fabric; the modification temperature of the polyester cotton fabric is 100-105 DEG C, the specification of the polyester cotton fabric is warp density 133 per inch, weft density 72 per inch, and grammage 120 g / m2; the number of the polyester cotton fabric is two groups, and the two groups of polyester cotton fabrics are sewn with hardening cloth.

[0007] Further, the hardening cloth is provided with connecting holes for sewing.

[0008] Further, the length of the hardening cloth is π / 2 times of the polyester cotton fabric 1.

[0009] Compared with the prior art, the utility model has the following beneficial effects:

[0010] By using the method of hardening first and then softening, the stitching can be better performed, and gaps can be generated in the fabric, which will not affect wearing after the hardened fabric is softened, and a relatively breathable structure is formed, and the subsequent fusion of silk protein onto the polyester cotton fabric greatly improves the skin friendliness of the fabric, and the friction between the modified fabric and the skin is reduced by 30%, and the wearing is more comfortable.

[0011] At the same time, the moisture absorption and breathability of the fabric are obviously improved, and the water absorption of the modified fabric is increased by 40% and the moisture permeability is increased by 35% compared with the unmodified fabric in the same time, which can quickly absorb and discharge human sweat and keep the skin dry.

[0012] In addition, the anti-ultraviolet performance of the fabric is also significantly improved, and the ultraviolet protection factor (UPF) is increased from 20 to 50+, which can effectively block the damage of ultraviolet rays to the human body. BRIEF DESCRIPTION OF DRAWINGS
