Abstract
The present invention relates to a real silk surface biological grafting hydrophobic finishing method. It is characterized by that said invention utilizes that under the action of lipase the carboxyl of silk protein on the real silk surface and high-grade fatty alcohol can produce esterification reaction to make hydrophobic hydrocarbon chain be grafted on the real silk so as to obtain permanent hydrophobic finished effect. The surface of said real silk fabric has hydrophobic property, and its interior still has good moisture sorption characteristics and air permeability.
Description
Technical field
The present invention relates to chemical industry, light textile technical field, particularly relate to a kind of silk broadcloth surface biological branch-meeting water-repellent finishing method.
Background technology
Pyridine complex is generally adopted in the fabric water repellent finish, and organosilicon compound all is to utilize the low surface tension of alkane to reach the purpose of refusing water.In cotton, polyester cotton blending, use morely, but aspect the silk water repellent finish, do not use substantially.
Pyridines micromolecule water repellent finishing agent can produce chemical bond with fabric, and arrangement has durability.But can be penetrated into fabric, not only produce the arrangement effect on the surface of fabric.Silicone based water repellent finishing agent since not can with fabric generation covalent bond, so arrangement only has durable～semi-durable.
The hydrophily of silk is very good, does not have WATER REPELLENCY fully, and this mainly is that silk not only has hydroxyl as cotton, also has charged carboxyl and amino.Charged group has strong polarization to hydrone, and its compatibility to water is more much bigger than hydroxyl.In the water repellent finish of silk, if not only introduce hydrophobic hydrocarbon chain, eliminate charged group simultaneously, its hydrophobic finishing can reach the effect of getting twice the result with half the effort.Up to the present, the research report that does not still have relevant silk broadcloth surface biological branch-meeting water-repellent finishing method.
Summary of the invention
The object of the present invention is to provide a kind of silk broadcloth surface biological branch-meeting water-repellent finishing method.This method utilizes the carboxyl and the higher aliphatic of the fibroin on silk broadcloth surface under action of lipase esterification to take place, and the hydrophobic hydrocarbon of higher alcohol is linked on the silk, reaches permanent hydrophobic finishing effect.
Under action of lipase, what higher aliphatic and silk took place is esterification, is connected on the silk with the form of covalent bond, so that water repellent finish has is permanent.Simultaneously, the carboxyl of fibroin superficial layer is eliminated, and charging property reduces, and has further increased hydrophobicity, makes the WATER REPELLENCY of fabric better.In addition, enzyme is a large biological molecule, can not be penetrated into fabric, and meeting Zhi Zuoyong can only carry out on the surface, can reach that water repellent finish only occurs in the surface and the purpose of not carrying out in fabric.Water repellent finish only occurs on the fabric face, and inner a large amount of hydrophilic radical is not affected, and still has good hygroscopicity and gas permeability.Connect and be connected on the carboxyl, and amino unaffected, therefore, do not influence the vital staining of fabric.
Silk broadcloth surface biological branch-meeting water-repellent finishing method of the present invention, realize through the following steps successively:
(1) be solvent with cyclohexane give, with the higher aliphatic dissolving of C12～C18, cyclohexane solvent added the suction molecular sieve drying before the preparation fatty alcohol solution, add phosphate buffer then, lipase was added mixing again;
(2) put into silk,, take out washing, dry getting final product then 450C insulation 48～72 hours.
Advantage of the present invention is:
Water repellent finish is to be connected on the fabric, and wash resistant can keep for a long time.Simultaneously, have only the surface to have WATER REPELLENCY, fabric still has good hygroscopicity and gas permeability.Silk broadcloth is refused the water grade and can be reached 3～4 grades after arrangement, refuses the water grade after the arrangement of inthegum silk fabric and reaches 4～5 grades.
