Problems solved by technology

However, when the human body sweats a lot, there will still be problems with moisture permeability, and the molecular chain structure of polyester is relatively tight, the degree of crystallinity is high, and there are few active groups on the macromolecules. It can only be carried out under certain conditions, the cost is high, and industrial production cannot be realized

Abstract

The invention discloses a method for preparing a nano-functional fiber with moisture absorption, sweat releasing and bacterial resistance. The method specifically includes the following steps: firstly, preparing sodium alginate microspheres, intercalating and compounding the microspheres between layers of organic montmorillonite to obtain a sodium alginate / montmorillonite composite material, performing polymer modification on the surface of the material, and compounding, extruding and granulating with polyamide and polyvinyl alcohol to prepare composite particles A; preparing porous titanium oxide nanocrystals, extruding and granulating with dried PET to prepare composite particles B, and finally putting the prepared composite particles A and B through skin-core composite spinning processing equipment to prepare a core-shell fiber with polyamide as a core layer and polyester as a surface layer, and sequentially washing the core-shell fiber with anhydrous ethanol and deionized water to obtain the product. The method is simple to operate, and the prepared fiber not only has good moisture absorption and sweat releasing performance, but also has good antibacterial performance, and the mechanical property is effectively improved.

Description

[0001] Technical field: [0002] The invention relates to the technical field of textiles, in particular to a preparation method of nano-functionalized moisture-absorbing, sweat-wicking and antibacterial fibers. [0003] Background technique: [0004] With the improvement of people's living standards, people's requirements for clothing are not only good-looking, but also higher and higher for the comfort, health, safety and environmental protection of clothing fabrics. Moisture-absorbing and sweat-wicking fabrics are widely used due to their strong water absorption capacity and sweat-wicking, breathable and moisture-permeable functions. The moisture permeability of textiles means that the fabric has the ability of the sweat emitted by the human body to pass through the fabric in the form of water vapor and dissipate to the surrounding environment. Fiber is the most commonly used material for clothing fabrics, and its structure and composition play a key role in the comfort of ...
