Problems solved by technology

Therefore, the slight friction of silk fabrics in dry air can easily generate a lot of static electricity, which can stimulate the nerves on the human body surface, and the red bumps on the skin can lead to dryness and keratinization of the skin. Dreams can easily lead to sub-health

Embodiment 1

[0014] The particle size is 15-25nm, the concentration is 0.45-8.0μg·mL -1 The nano-silver liquid is added to a solvent composed of glycerol and water, and the volume ratio of glycerol to water is 1: 2, as a nano-silver dispersion. Dissolve polyvinylpyrrolidone in a solvent composed of glycerol and water, the volume ratio of glycerol to water is 1:0.2, heat to 105°C, put mulberry silk fiber, mulberry silk fiber and solvent into the above solvent The volume ratio is 1:1.5, reflux for 20 minutes, spray the nano-silver dispersion liquid in the reflux mulberry silk fiber and react with the solvent for 2 hours, separate, and wash with deionized water. Soak the washed mulberry silk fibers in 2% polylactic acid solution to regularize the fiber shape, and then vacuum dry to obtain nano silver mulberry silk fibers.

Embodiment 2

[0016] In the above-mentioned process, it is selected that the average diameter is 245nm, and the minimum diameter is 54nm mulberry silk fiber raw material.

Abstract

The invention discloses a method for preparing mulberry silk and products for preventing static electricity and shielding electromagnetic waves and belongs to a preparation method of the mulberry silk and products. The method comprises the following steps: adding a nano-silver solution into a solvent consisting of glycerol and water to serve as a nano-silver dispersing solution, dissolving polyvinyl pyrrolidone into the solvent consisting of glycerol and water, putting mulberry silk fibers, spraying the nano-silver dispersing solution, refluxing, separating and washing; and normalizing fiber morphology in polylactic acid solution, and performing vacuum drying to obtain the product. The fabric has a good effect of preventing static electricity and shielding electromagnetic waves, the breaking strength of the fiber is enhanced, and the flexibility is improved.

Description

technical field [0001] The invention belongs to a preparation method of mulberry silk and its products, in particular to the preparation of antistatic and electromagnetic shielding functional mulberry silk and its products. Background technique [0002] Like other animal and plant proteins, silk protein contains acidic amino acid residues and basic amino acid residues. Acidic amino acid residues ionize H + To make the protein negatively charged, basic amino acid residues can bind H + making the protein positively charged. At the same time, cysteine ​​residues and tyrosine residues can also ionize H + making the protein negatively charged. Therefore, the slight friction of silk fabrics in dry air can easily generate a lot of static electricity, which can stimulate the nerves on the human body surface, and the red bumps on the skin can lead to dryness and keratinization of the skin. Dreams can easily cause sub-health. [0003] Due to the electromagnetic shielding...
