Method for preparing mulberry silk containing nanometer TiO2

Abstract

The invention discloses a method for preparing mulberry silk containing nanometer TiO2. According to the method, firstly, the nanometer TiO2 is prepared into additive solution with the concentration being 100 too 150mg / L, then, the solution is sprayed onto mulberry leaves according to the use dosage that 1.0L of solution is added to 100kg of mulberry leaves, the mulberry leaves are fed to bombyx mori from the fifth instar stage to the 3rd day after being dried until the mounting, in the produced mulberry silk, the content of Ti element is 440+ / -21 to 500+ / -25ng / g, after the silk is washed for 50 times trough water, the content of Ti element is 418+ / -19 to 465+ / -30ng / g, good combination of nanometer TiO2 and silk protein is shown, and water washing resistance and high stability are realized. The method provided by the invention does not adopt chemical agents, the preparation of the mulberry silk containing nanometer TiO2 is realized, and a new research thought is provided for the mulberry silk modification research. The disclosed method has the advantages that the practicability is high, the operation is convenient, the cost is low, the popularization and the application are easy, and the influence cannot be generated on the environment.

Description

technical field [0001] The invention relates to a method for preparing mulberry silk modified by nanoparticles, in particular to a method containing nano-TiO 2 Preparation method of mulberry silk. Background technique [0002] silkworm, also known as silkworm ( Bombyx mori ), is an important silk insect. The mulberry silk produced has the advantages of good moisture absorption, warmth retention and wearing comfort, softness, smoothness and strong elasticity. Silk fabric has soft luster, elegant and gorgeous, smooth hand feeling, and has natural health care functions unmatched by other chemical fibers. It is known as the "fiber queen". [0003] However, if mulberry silk is exposed to sunlight for a long time, it will turn yellow and age, and its anti-wrinkle performance is poor, and it is easy to breed pathogenic microorganisms. To improve the above shortcomings of mulberry silk is a hot spot in researching the modification of mulberry silk in recent years. [0004] Due t...

Problems solved by technology

[0005] In the prior art, taking mulberry silk as an object, the surface of mulberry silk is modified by using chemical reagent dimethylol dihydroxy ethylene urea resin, and the nano-TiO 2 Combined with the surface of silk; a small amount of nano-TiO can also be combined with the chemical reagent tetrabutyl titanate 2 Combined into the tiny voids inside the fiber; but due to the use of chemical reagents, the natural properties of mulberry silk have been changed to a certain extent, and the modified mulberry silk cannot be recognized by consumers, and in the materials obtained by this method, Nano-TiO 2 Poor adhesion to mulberry silk
