The invention discloses a kind of preparation method of the silk fiber of high health properties, it is characterised in that comprises the following steps：A, silk cocoon is passed through into degumming, dried, be placed in lithium-bromide solution and dissolve completely, then through dialysis, high speed centrifugation and concentration, obtain fibroin solutions；B, pearl powder colloidal sol is added in fibroin solutions, adds glycerine after being sufficiently stirred, add sodium chloride and be uniformly mixing to obtain spinning solution；C, hydrogen peroxide is added into spinning solution, adjusts the temperature to 45 55 DEG C, continues to stir, is cooled down, sodium nitrite solution is added dropwise in ice-water bath and obtains being modified spinning solution；D, modified spinning solution is subjected to spinning, is dipped in ethanol water placement, then thermally treated obtain the silk fiber of high health properties.Its ultimate strength of the silk fiber that the present invention is prepared and elongation at break are without significant changes；But full wire silk fabric nightwear made of the silk fiber of the dress present invention, the length of one's sleep and sleeper effect are significantly increased.
Description
Technical field
The present invention relates to textile technology field, especially, is related to a kind of preparation method of the silk fiber of high health properties.
Background technology
With economic and society development, the improvement of people's living standards, requirement of the people to fabric also more and more higher, people
The fabric of dressing need often in face of the challenge pullled of tear, therefore just need a kind of good silk fibroin of comfortable mechanics effect
Tie up fabric.
Silk fiber is natural fiber, has good mechanical property, has good affinity with human body skin, existing
Research is found, silkworm is fixed, and carrying out external force traction to silkworm reels off raw silk from cocoons, and the mechanical strength of silk can be improved into 20-30%, prepared
The silk of high intensity, Chinese patent CN105696098A（Publication date 2016.06.22）Also disclose that the list that a kind of Strengthening and Toughening is modified
Silk nanometer silk fiber and preparation method thereof, using fibroin, nano-pearl powder particles, graphene oxide and thickener as original
Material prepares spinning solution, and nascent monofilament nanometer silk fiber is obtained through electrostatic spinning and the bar-shaped reception device of rotation, then through pre- knot
Monofilament nanometer silk fiber that is brilliant and being thermally treated resulting in Strengthening and Toughening modification, the nanometer that obtained nanometer silk fiber is prepared with tradition
The mechanical property of silk fiber significantly improves.
But as people gradually step up to fabric requirement, it is necessary to study a kind of silk fibroin with high health properties
