Embodiment 1

[0026] (1) After the silk is degummed, it is added to a calcium chloride solution with a concentration of 2%, and it is swelled at 70°C for 5 minutes, and then the swollen silk fiber is kneaded and carded to obtain a fibrillation degree of 20%. of silk fibers.

[0027] (2) In parts by weight, add sodium alginate solution, cornstarch and honeysuckle extract to the chitosan solution with a low molecular weight of 85% deacetylation degree, stir until mixed evenly, and form a moisture-absorbing and moisturizing finishing agent, wherein low 5 parts of molecular weight chitosan, 3 parts of sodium alginate, 2 parts of corn starch, 1 part of honeysuckle and 50 parts of deionized water.

[0028] (3) After the finely fibrillated silk fibers prepared in step (1) are dried at room temperature, they are immersed in the moisture-absorbing and moisturizing finishing agent prepared in step (2) at 25° C. to completely wet them, taken out, dried at 60° C., and then Immerse in the silk fibroin ...

Embodiment 2

[0030] (1) After the silk is degummed, it is added to a calcium chloride solution with a concentration of 4%, and it is swelled at 80°C for 15 minutes, and then the swollen silk fiber is rubbed and carded to obtain a fibrillation degree of 35%. of silk fibers.

[0031] (2) In parts by weight, add sodium alginate solution, cornstarch and honeysuckle extract to the chitosan solution with a low molecular weight of 95% deacetylation degree, stir until mixed evenly, and form a moisture-absorbing and moisturizing finishing agent, wherein low 15 parts of chitosan with molecular weight, 7 parts of sodium alginate, 8 parts of corn starch, 5 parts of honeysuckle and 80 parts of deionized water.

[0032] (3) After the finely fibrillated silk fibers prepared in step (1) are dried at room temperature, they are immersed in the moisture-absorbing and moisturizing finishing agent prepared in step (2) at 30° C. to completely wet them, taken out, dried at 70° C., and then Immerse in the silk f...

Embodiment 3

[0034] (1) After the silk is degummed, it is added to a calcium chloride solution with a concentration of 3%, and it is swelled at 75°C for 10 minutes, and then the swollen silk fiber is kneaded and carded to obtain a fibrillation degree of 25%. of silk fibers.

[0035] (2) In parts by weight, add sodium alginate solution, cornstarch and honeysuckle extract to the chitosan solution with a low molecular weight of 90% deacetylation degree, stir until mixed evenly, and form a moisture-absorbing and moisturizing finishing agent, wherein low 10 parts of chitosan with molecular weight, 5 parts of sodium alginate, 4 parts of corn starch, 2 parts of honeysuckle and 60 parts of deionized water.

[0036] (3) After the finely fibrillated silk fibers prepared in step (1) are dried at room temperature, they are immersed in the moisture-absorbing and moisturizing finishing agent prepared in step (2) at 27° C. to completely wet them, taken out, dried at 65° C., and then Immerse in the silk ...

Abstract

The invention provides modified silk fiber with high moisture absorbability and moisture retentivity and a preparing method thereof. Fibrillated silk fiber is used as the raw material, chitosan low in molecular weight, sodium alga acid, corn starch and honeysuckle flower are used as a finishing agent high in moisture absorbability and moisture retentivity, and the raw material is impregnated in the finishing agent high in moisture absorbability and moisture retentivity and silk fibroin solution in sequence and then subjected to steaming processing and sizing, washing and drying to generate the modified silk fiber with high moisture absorbability and moisture retentivity. The modified silk fiber is high in fibrillation degree and excellent in moisture absorbability and moisture retentivity, the practicality of the silk fiber is improved through silk fibroin curing and finishing, and the intrinsic properties of silk are protected to the maximum extent.

Description

Technical field: [0001] The invention belongs to the technical field of textile materials, and in particular relates to a modified silk fiber with high hygroscopicity and moisture retention and a preparation method thereof. Background technique: [0002] With the gradual improvement of people's living standards, people have put forward higher requirements on the clothing fabric itself, not only to be durable and comfortable, but also to have antibacterial and antibacterial functions. As we all know, silk fiber has always been famous for its skin-friendly comfort and certain health benefits, but the hygroscopicity of silk fiber is not high, and the moisture regain is only 11%, which greatly limits the application of silk fiber in the field of moisture absorption. [0003] Chinese patent CN 104213248A (disclosure date December 17, 2014) discloses a moisture-absorbing and breathable silk composite fiber and a preparation method thereof, first decocting frankincense, alba, and h...
