Problems solved by technology

There are some deficiencies in the anti-ultraviolet finishing scheme of silk after finishing, the most prominent is that the anti-ultraviolet function provided by the post-finishing is poor in durability. For example, the anti-ultraviolet parasol will deteriorate or even disappear after being exposed to rain.

Abstract

The invention claims an anti-ultraviolet true silk and a preparation method thereof. The method comprises the following steps of: carrying out emulsion treatment on a monomer which is cage-type carborane containing an unsaturated branch chain, and carrying out chemical grafting on true silk; and then carrying out post-treatment to prepare a true silk macromolecule grafting copolymer containing a gather cage type carborane side chain, wherein the true silk macromolecule grafting copolymer has the anti-ultraviolet performance. The invention adopts the technical scheme that the cage-type carborane is grafted on the true silk fiber macromolecule chain to realize the efficacy of permanent anti-ultraviolet of the true silk. Boron atoms in the structure of the used ultraviolet absorbent cage-type carborane are stacked densely to have the excellent function of radiation protection. The anti-ultraviolet true silk has the advantages of simple preparation process condition and wide application prospect and is easy to industrialize.

Description

technical field [0001] The invention relates to an anti-ultraviolet real silk and a preparation method thereof, in particular to a process of chemically grafting and modifying real silk by using cage-type carborane containing unsaturated branched chains as a raw material to prepare a The anti-ultraviolet real silk belongs to the field of textile chemistry and application. Background technique [0002] Silk is a kind of natural protein fiber, which is widely used in the textile field due to its superior mechanical strength and hand feeling, and is known as the "fiber queen" and is loved by people. However, the UV penetration rate of real silk fabrics is high, so it is imperative to carry out anti-ultraviolet finishing on them. Since the ultraviolet rays that cause direct harm to the human body are mainly the UV-A segment with a wavelength of 400-320um and the UV-B segment with a wavelength of 320-290um, UV protection is mainly carried out for these two bands. [0003] At pr...
