Abstract

The invention relates to the field of cloth, in particular to degradable antistatic non-woven fabric. Raw materials of the degradable antistatic non-woven fabric includes modified polyester fibers, and a preparation method of the modified polyester fibers includes the following steps: S1, preparation of a modifier: weighing Nicandra physaloides(L)Gaertn seeds, and soaking the Nicandra physaloides(L)Gaertn seeds in water for the first time to obtain an extracting solution A; taking out the Nicandra physaloides(L)Gaertn seeds, and soaking for the second time to obtain an extracting solution B; combining the extracting solution A and the extracting solution B, evaporating and concentrating to obtain the modifier; S2, modification of polyester fibers: soaking the polyester fibers in a calcium chloride solution, fishing out and air-drying; and S23, soaking the polyester fibers in the modifier, fishing out and drying to prepare the modified polyester fibers. The materials of the non-woven fabric are degradable, and degraded products can be recycled, so that the non-woven fabric is green and environmentally friendly; Nicandra physaloides(L)Gaertn seed gel layers coat the surfaces of the polyester fibers, so that the water absorption performance and the antistatic performance of the non-woven fabric are improved.

Description

technical field [0001] This application relates to the field of cloth, more specifically, it relates to a degradable antistatic non-woven fabric. Background technique [0002] Non-woven fabrics, also known as non-woven fabrics, are composed of directional or random fibers. It is called cloth because of its appearance and certain properties. Non-woven fabrics have many advantages such as moisture-proof, breathable, flexible, light weight, non-combustible, easy to decompose, non-toxic and non-irritating, rich in color, low in price, and recyclable. [0003] In the process of use and washing, non-woven fabrics are prone to deformation and creases due to continuous exposure to external forces, resulting in a decrease in the flatness of non-woven fabrics, affecting the use of non-woven fabrics, and also affecting the appearance of non-woven fabrics. [0004] In order to improve the wrinkle resistance of the produced spunlace nonwoven fabric, synthetic fibers or composite fibers...
