Antibacterial bamboo charcoal fiber flyknit vamp

Abstract

The invention discloses an antibacterial bamboo charcoal fiber flyknit vamp. Fiber comprises nano-silver bamboo charcoal fiber of a core part and a TPU surface layer coating the nano-silver bamboo charcoal fiber of the core part. According to the invention, the structure of the fiber of the knitted vamp is improved, nano-silver bamboo charcoal dispersion liquid and viscose fiber pulp are spun to form bamboo charcoal fiber, nano-silver is directly and integrally embedded in the bamboo charcoal fiber, and the TPU surface layer coats the periphery of the bamboo charcoal fiber to improve the stability of the nano-silver again and prevent nano-silver particles from falling off; in addition, the TPU surface layer is formed by supercritical foaming, and a plurality of pore channels are formed in the surface layer; in a walking process, the knitted vamp is extruded, and the pore channels in the TPU surface layer are continuously pressed and recovered, so that gas in the vamp is quickly and frequently contacted with the nano-silver bamboo charcoal fiber of the core part through the pore channels, and the nano-silver is used for sterilizing the vamp; and the vamp with the structure has the advantages that the nano-silver particles are stable and do not fall off, and the sterilizing effect is good.

Description

technical field [0001] The invention relates to the technical field of footwear materials, in particular to an antibacterial bamboo charcoal fiber fly-woven shoe upper. Background technique [0002] Footwear is a necessity of life, and there are many types. During long-term walking, the feet are prone to sweat, which in turn breeds bacteria, fungi, etc., resulting in odor or athlete's foot. At present, in addition to maintaining hygiene and brushing frequently, There is no other effective solution to eliminate the above phenomenon, but in order to alleviate or partially eliminate the above phenomenon, there are bactericidal uppers on the market. For example, the upper is a multi-layer structure with a bactericidal layer between the bottom layer and the top layer. The structure is complicated. , is not easy to form, and thicker is not easy to ventilate, or is woven vamp with bamboo charcoal fiber, sterilizes with the characteristic of bamboo charcoal fiber, but sterilizing ab...

[0002] Footwear is a necessity of life, and there are many types. During long-term walking, the feet are prone to sweat, which in turn breeds bacteria, fungi, etc., resulting in odor or athlete's foot. At present, in addition to maintaining hygiene and brushing frequently, There is no other effective solution to eliminate the above phenomenon, but in order to alleviate or partially eliminate the above phenomenon, there are bactericidal uppers on the market. For example, the upper is a multi-layer structure with a bactericidal layer between the bottom layer and the top layer. The structure is complicated. , is not easy to form, and thicker is not easy to ventilate, or is woven vamp with bamboo charcoal fiber, sterilizes with the characteristic of bamboo charcoal fiber, but sterilizing ability can not meet demand, or disclose a kind of bamboo charcoal fiber as in the patent of application number CN2007100276721, its Fibers are formed by spinning nano-silver and viscose, and then can be woven into shoe uppers. However, the disadvantage of this structure is that the stability of nano-silver on the fiber is still not enough, there is a phenomenon of shedding, and the antibacterial durability is poor, which needs to be improved.
