Problems solved by technology

It can be seen that the ultra-soft, highly hygroscopic fibers or fabrics currently prepared are mostly prepared by blending a variety of functional fibers to make full use of the different characteristics of various fibers to prepare low-twisted or untwisted fibers or fabrics. Simple, good economic benefits, but the preparation process of this method is cumbersome, low-tech, easy to be replaced by the market, and the blended fibers prepared by this method still contain chemical fibers, and its environmental protection is still not comparable to pure natural fibers

Embodiment 1

[0027] (1) After the silk fibers were boiled and degummed, they were immersed in warm water at 30°C for swelling treatment for 30 minutes, and then rubbed and rubbed at a frequency of 30 times / min for 1 minute at a strength of 1 N to obtain pretreated silk fibers.

[0028] (2) The pretreated silk fiber prepared in step (1) is immersed in a solution containing 10nm nano-hydrogel particles of 20g / ml, ultrasonically oscillated for 20min at a frequency of 100W, taken out, and dried to obtain a water content of 8 % of highly hygroscopic silk fibers.

[0029] (3) Add the highly hygroscopic silk fiber prepared in step (2) into ice water with a bath ratio of 1:40, heat and stir slowly, add S114 alkaline protease at 40 activity units / ml, and take it out after reacting at 35°C for 30 minutes. Fully wash, dry naturally to get super soft and highly hygroscopic silk fibers.

Embodiment 2

[0031] (1) After the silk fibers were boiled and degummed, they were immersed in warm water at 40°C for swelling treatment for 50 minutes, and then rubbed and rubbed at a frequency of 30 times / min for 10 minutes under a strength of 3N to obtain pretreated silk fibers.

[0032] (2) The pretreated silk fiber prepared by step (1) is immersed in the solution containing 100nm nano-hydrogel particles of 40g / ml, ultrasonically oscillated for 60min at a frequency of 150W, taken out, and dried to obtain a water content of 15 % of highly hygroscopic silk fibers.

[0033] (3) Add the highly hygroscopic silk fiber prepared in step (2) into ice water with a bath ratio of 1:40, heat and stir slowly, add 60 activity units / ml of 2709 alkaline protease, and take it out after reacting at 40°C for 90 minutes. Fully wash, dry naturally to get super soft and highly hygroscopic silk fibers.

Embodiment 3

[0035] (1) After the silk fibers were boiled and degummed, they were immersed in warm water at 35°C for swelling treatment for 40 minutes, and then rubbed and rubbed at a frequency of 30 times / min for 5 minutes at a strength of 2N to obtain pretreated silk fibers.

[0036] (2) The pretreated silk fiber prepared by step (1) is immersed in the solution containing 50nm nano-hydrogel particles of 30g / ml, ultrasonically oscillated for 30min at a frequency of 120W, taken out, and dried to obtain a water content of 10 % of highly hygroscopic silk fibers.

[0037] (3) Add the highly hygroscopic silk fiber prepared in step (2) into ice water with a bath ratio of 1:40, heat and stir slowly, add S114 alkaline protease at 50 activity units / ml, and take it out after reacting at 40°C for 60 minutes. Fully wash, dry naturally to get super soft and highly hygroscopic silk fibers.

Abstract

The invention provides a preparation method of super-soft and highly-hygroscopic silk fibers. The preparation method comprises the following specific steps of firstly, boiling and degumming silk fibers, and then immersing the silk fibers into warm water for performing swelling treatment; performing rubbing friction to obtain pretreated silk fibers; secondly, immersing the pretreated silk fibers into a solution containing nano-hydrogel particles, performing ultrasonic oscillation, taking out and spinning to obtain highly-hygroscopic silk fibers; adding the highly-hygroscopic fibers into ice water, and slowly heating and stirring; adding biological enzyme, reacting for a period of time, then taking out, sufficiently washing and naturally airing to obtain the super-soft and highly-hygroscopic silk fibers. The natural silk fibers prepared by the method are modified by physical and biological methods to be endowed with super-soft and highly-hygroscopic properties; no chemical reagent is added, no toxicity and residues are caused, and the nature of the silk fibers is retained, so the super-soft and highly-hygroscopic silk fibers are environmentally-friendly.

Description

Technical field: [0001] The invention belongs to the technical field of textile materials, and in particular relates to a method for preparing supersoft and highly hygroscopic silk fibers. Background technique: [0002] Fibers and fabrics currently on the market generally have poor softness and water absorption, and there are not many fibers or fabrics that are super soft and highly hygroscopic. Moreover, with the continuous advancement of science and technology, more and more people pay more and more attention to multifunctional green and environmentally friendly textiles. In order to meet people's needs, most of them are prepared by combining chemical functional fibers with natural fibers at present. Therefore, most of the super soft and highly water-absorbent functional fibers are made of functional chemical fibers and natural fibers as raw materials through processes such as merging, twisting, and weaving. [0003] Chinese patent CN 1257321C discloses a high water absor...
