A kind of wool fabric functional finishing agent and functional finishing method

Abstract

The invention discloses a functional wool fabric finishing agent. The functional wool fabric finishing agent is a water solution prepared from transglutaminase, chitosan and an acidic regulator; the pH value of the functional wool fabric finishing agent is 2.3-3.8, wherein the concentration of the transglutaminase is 1g / L-100g / L. The invention also discloses a functional wool fabric finishing method; the method comprises the concrete steps of dipping pretreated wool fabric into the functional wool fabric finishing agent, wherein a bath ratio is (1: 10)-(1: 20); adding a cross-linking agent, then heating up to 45-60 DEG C, dipping for 1-5h and then washing with hot water with the temperature of 90-100 DEG C for 3-5min to terminate a reaction; finally, washing with water again, and drying to obtain the finished wool fabric, wherein the adding amount of the cross-linking agent is 100-150g / L. After the wool fabric is treated by the functional wool fabric finishing agent and the functional wool fabric finishing method, the properties such as durability, antibacterial property and ultraviolet resistance of the wool fabric are improved, and the wool fabric has a certain health care function so as to improve the immunity of a human body.

Description

technical field [0001] The invention relates to the technical field of wool fabric functional finishing, in particular to a wool fabric functional finishing agent and a functional finishing method using the wool fabric functional finishing agent. Background technique [0002] With the improvement of people's living standards and the deepening of people's awareness of the hazards of textile chemical finishing agents, people pay more attention to the selection of fabrics. Among them, natural fiber fabrics, especially wool fabrics, have become the first choice for consumers who care about health, comfort and environmental protection. However, natural fiber fabrics or wool fabrics themselves also have some performance deficiencies and defects to a certain extent, especially the lack of diverse functions that are beneficial to the human body, which has also become an important topic in the research and development of textile technology. The development of functional finishing tec...

Problems solved by technology

[0003] As far as wool fabric is concerned, in order to improve the durability and antibacterial properties of wool fabric, it is generally necessary to use chemical treatment to functionally finish wool fabric, but the finishing process will cause certain damage to wool fabric itself, and the wool fabric after finishing No further treatment, so the wool fabric has no significant change in wrinkle resistance and mechanical properties, and it is difficult to meet the high requirements of modern people for the comfort of wool fabrics

[0004] The patent No. is 200810235391X, and the patent titled the enzyme-catalyzed grafting functional finishing method of wool discloses a technical scheme, which also effectively improves the anti-felting property of wool fabrics, improves the washability and anti-shrinkage properties of wool fabrics Bacterial effect, but the inventor of the present application did not obtain all the effects claimed in the patent when using the patent for testing, and the detected data fluctuated greatly, and the specific reason could not be found
