Abstract

The invention provides a crease-resistant fabric and a preparation method thereof. The crease-resistant fabric is prepared by mixing a cotton fabric, modified cellulose, a silane coupling agent and graphene oxide, wherein the modified cellulose has a structure shown in a formula I, and in the formula I, n is equal to 100 to 500. The fabric has good crease-resistant performance, the antibacterial and bacteriostatic performance of the material is improved, the mechanical property of the fabric is improved to a certain degree, the smooth feeling and the thick feeling of the fabric can be obviously improved, and the fabric has a remarkable application prospect.

Description

technical field [0001] The invention relates to the technical field of fabrics, in particular to a wrinkle-resistant fabric and a preparation method thereof. Background technique [0002] With the improvement of people's living standards, material life is becoming more and more abundant, and more and higher requirements are put forward for the safety, health, comfort and environmental protection of textiles. Among the numerous textile fiber varieties, regenerated cellulose products such as silk, cotton, linen, viscose, and Tencel (Tencel) among natural fibers are more and more favored by consumers. However, the textiles of these fiber varieties have the disadvantages of poor fabric elasticity, easy wrinkling, and poor appearance retention, which reduces the grade of the product. Chemical fiber synthetic fabrics generally have better wrinkle resistance due to their own structural characteristics. For example, polyester has a large elastic modulus and is not easily deformed b...
