Abstract

The invention discloses a natural silk anti-crease agent which is a compound described as follows: wherein A and B are described as follows. The natural silk anti-crease agent can be applied to natural silks, hetero active polyfunctional groups in molecules of the anti-crease agent and natural silk fiber macromolecules are subjected to chemical crosslinking to generate a network structure to prevent the slippage of fiber macromolecules and improve the washable crease resistance of the natural silks. The invention also discloses a preparation method of the natural silk anti-crease agent. Raw materials are easy and simple to obtain, and a synthetic process is relatively simple, and has low requirement on professional level of operators.

Description

technical field [0001] The invention relates to the field of fabric anti-wrinkle agents, in particular to a real silk anti-wrinkle agent, a preparation method thereof and an application in real silk. Background technique [0002] Silk fabrics are favored by consumers because of their elegant luster, soft feel, light and elegant style, certain health care functions and excellent wearing comfort. However, silk fabrics have poor elasticity and easy wrinkling during use. Disadvantages, thus affecting the consumption of silk fabrics to a large extent. Over the years, the industry has been working hard to improve these defects, and achieved some good results. The methods to improve the anti-wrinkle performance of silk can be summarized into two categories: one is the physical method, through the change of raw materials and weaving methods or through the action of external force, the physical shape of the real silk is changed to improve and enhance the anti-wrinkle method; the oth...
