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 preparation method of nano-functionalized moisture-absorbing and sweat-wicking antibacterial fibers, which specifically includes the following steps: firstly, preparing sodium alginate microspheres, and intercalating them into the interlayer of organic montmorillonite to obtain sodium alginate montmorillonite / montmorillonite composite material, the surface of which is modified by polymer and compounded with polyamide and polyvinyl alcohol for composite extrusion and granulation to prepare composite particles A; porous titanium oxide nanocrystals are prepared, and they are extruded with dry PET to make composite particles A. Finally, the obtained composite particles A and B are prepared by skin-core composite spinning processing equipment to obtain core-shell fibers with polyamide as the core layer and polyester as the surface layer. Wash with water ethanol and deionized water to obtain the product. The method is simple to operate, and the prepared fibers not only have good moisture absorption and perspiration-wicking properties, but also have good antibacterial properties, and the mechanical properties are also effectively improved.

Description

Technical field: [0001] 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. Background technique: [0002] 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 clothing. Ther...
