Problems solved by technology

[0003] At present, there are mainly two methods of antibacterial textiles developed at home and abroad: one is to add antibacterial agents in the fiber production process to produce antibacterial fibers, and the fabrics produced by using such fibers have permanent antibacterial functions; but this method has high processing costs. , high technical requirements, large amount of antibacterial agent, and difficult to control the distribution, etc., and this method is only suitable for adding antibacterial agents to chemical fibers, not suitable for natural fiber fabrics
The second method is antibacterial finishing, such as surface coating, resin finishing, etc. Although the processing method is simple, the antibacterial agent only adheres to the surface of the fabric, and the initial antibacterial agent dissolves a large amount, and the antibacterial effect gradually decreases with the number of washings. The safety, safety and feel are greatly affected, so neither of these methods is a good way to develop antimicrobial textiles

Embodiment 1

[0030] Embodiment 1: An antibacterial nanofiber yarn, including a core and a skin layer that is completely and evenly coated on the outer surface of the core; the core is polyester filaments, and the skin is polyacrylonitrile (PAN) electrospun nanofibers, Triclosan, an organic broad-spectrum antibacterial agent, is evenly distributed inside the electrospun nanofibers. see figure 1 The longitudinal SEM picture of the antibacterial nanofiber yarn of the present invention in, and figure 2 Comparing the SEM pictures of ordinary polyester filaments in the above shows that the polyacrylonitrile / triclosan nanofibers with antibacterial function are completely covered on the surface of polyester filaments, making the antibacterial nanofiber yarns have good antibacterial properties. In addition, the diameter of the nanofiber is much smaller than that of the polyester filament, and it has a very large specific surface area, large porosity and wicking performance, which will endow the a...

Embodiment 2

[0031] Embodiment 2: An antibacterial nanofiber yarn, the difference from Example 1 is that the core is a nylon filament, and the cortex is an electrospun polypropylene nanofiber, which is evenly distributed inside the electrospun polypropylene nanofiber There are inorganic antibacterial agent nano silver particles.

Embodiment 3

[0032] Embodiment 3: A kind of antibacterial nanofiber yarn, the difference with embodiment 1 is that the core is an acrylic filament, and the cortex is an electrospun polylactic acid nanofiber, which is evenly distributed inside the electrospun polylactic acid nanofiber Nanoscale TiO 2 particle.

Abstract

The invention discloses antibacterial nanofiber yarn and a preparation method thereof. The yarn comprises a core part and a surface layer uniformly coating the outer surface of the core part, wherein the core part adopts filament yarn or chopped fiber yarn, the surface layer adopts electrostatic spinning nanofibers, and an antibacterial agent is uniformly distributed in the electrostatic spinning nanofibers. The preparation method adopts a one-step forming production technology with a nanofiber yarn machine, and the yarn surface is directly coated with the antibacterial nanofibers under coupling of positive and negative electric fields. The antibacterial nanofiber yarn can realize comprehensive effects of bacteria resistance, bacteriostasis, hydrophilicity and comfort through combination of the spinning yarn, the nanofibers and the antibacterial agent, has good heat resistance and washability, is formed once in a production process, can save the cost and energy effectively and has higher added value.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to an antibacterial nanofiber yarn and a preparation method thereof. Background technique [0002] Due to the microporous structure of textiles, factors such as the body temperature (temperature) of the wearer itself, the moisture (moisture) emitted by the human body, and the metabolites (nutrition) of the skin provide a suitable growth environment for microorganisms, making textiles the most suitable environment for bacteria. A hotbed for the growth and reproduction of microorganisms such as fungi. Bacteria growing on textiles will not only cause discoloration, mildew, embrittlement and degradation of fiber products, but also easily produce abnormal irritation to human skin and induce various skin diseases, affecting human health. Research and development of textiles with antibacterial function is one of the effective ways to protect people from or less affected by bacteria, whic...
