Embodiment 1

[0038] The preparation method of the hygroscopic and heating fiber containing plant extracts with antibacterial function, taking the preparation of 1.33dtex×38mm as an example, includes the following steps:

[0039] Step 1, the preparation of spinning solution:

[0040] Cellulose pulp and A-type cellulose (A-type cellulose can be cotton fiber or hemp fiber) are mixed according to a weight ratio of 1:2, and then 10% of a composite modification additive is added, and a stirrer is used for high-speed stirring to realize blending. The blended spinning solution is made, and then it is set aside, passed through, defoamed, and matured for later use;

[0041] Step 2, spinning and forming:

[0042] The spinning solution in step 1 is processed by a metering pump and a filter, the spinning speed is set in advance, the spinning solution is sprayed out through the spinneret, and enters the coagulation bath, where it reacts with the reagents and solidifies, and the formed fiber bundle It ...

Abstract

The invention discloses a preparation method of moisture-absorbing heating fibers containing plant extracts and having an antibacterial function, which comprises the following steps: step 1, preparation of a spinning solution: mixing cellulose pulp with alpha cellulose according to a weight ratio of 1: 2, then adding 10-18% of a composite modified additive, stirring at a high speed by using a stirrer to realize blending to prepare a blended spinning solution, and standing, defoaming, and ripening for later use; and 2) spinning and forming: in which the spinning solution obtained in the first step is treated through a metering pump and a filter, the spinning speed is preset, the spinning solution is sprayed out through a spinning nozzle, enters a coagulating bath and reacts with reagents in the coagulating bath to be cured, and formed fiber bundles need to be stretched through a drafting roller firstly and then subjected to post-processing treatment. The product is fine, soft, moisture-preserving, breathable, non-irritating to skin affinity, excellent in moisture absorption and heating performance and antibacterial property, green, environment-friendly, biodegradable, free of heavy metals and harmful chemicals, safe and non-dissolving out; and the fiber has high moisture regain and high hygroscopicity.

Description

technical field [0001] The invention relates to the technical field of regenerated cellulose fibers, in particular to a method for preparing hygroscopic and heating fibers containing plant extracts and having antibacterial functions. Background technique [0002] With the improvement of scientific and technological living standards, people will pay more and more attention to the quality of life, so the hygiene, health and comfort of textiles will receive more and more attention. In the cold winter, what people pursue is no longer simple cold protection and warmth, but more attention is paid to the light and thin fabrics that can generate heat independently and keep warm for a long time. The consumer market is increasingly favoring multi-functional textile thermal materials to meet people's diversified requirements for comfort and warmth. The market prospect of moisture-absorbing and heating fibers is promising. The research and development of hygroscopic and heating fibers w...
