Problems solved by technology

However, the alkali reduction will reduce the polyester fabric's stiffness, wrinkle elasticity and other wearing properties, and the increased hydroxyl group is very small, and the grafted protein is not firm and will fall off. Therefore, there is basically no application prospect

Abstract

The invention relates to a method for endowing terylene with functional group by means of inlaying. The method comprises the following steps: making use of inlaying principles and providing appropriate conditions to generate gaps among molecular chain segments of terylene fiber; inlaying functional group, which contains hydroxyl, amido and the like and can carry out chemical reaction, between the molecular chain segments of the terylene fiber; a compound containing the functional group is firmly locked in the terylene fiber after external conditions are removed, thereby endowing the terylene with a great amount of functional groups and ensuring that the surface of terylene can be grafted with protein or undergoes other processing to prepare the terylene fiber with better performances. The method is simple and easy to carry out and does not influence the wearing performance of the terylene fiber.

Description

technical field [0001] The invention relates to the technical field of textile engineering, in particular to a method for imparting functional groups to polyester fibers and fabrics, thereby using the functional groups of polyester fibers to graft proteins and dye them, to change the processing properties of polyester, and to develop new polyester products. Background technique [0002] Polyester is the fiber with the most outstanding wearing performance among chemical fibers, and its consumption is more than the sum of all other chemical fibers. Polyester has good crispness, wrinkle elasticity, and washable and wearable properties. The chemical raw material of polyester is polyethylene terephthalate (PET). Except for a very small amount of hydroxyl groups at the end of the polymer, there are basically no usable groups on the surface of polyester fibers. Therefore, the development of new products in polyester processing is limited. Grafting biocompatible proteins on the su...
