A kind of antibacterial flame-retardant yarn and its production process

Abstract

The invention provides an antibiotic flame-retardant yarn and a production process thereof. The yarn comprises a core layer and a surface layer wrapping the outer wall of the core layer, the core layer is formed by intertwining an antibiotic strand and a flame-retardant strand, and the surface layer comprises an antibiotic coating, a heat insulation fibrous layer and a flame-retardant coating which are successively arranged at the surface of the core layer from the inside to the outside; the antibiotic strand is formed by blending a nanometer titanium dioxide catalyst fiber with a bamboo charcoal fiber; and the flame-retardant strand is formed by blending a PPT fiber with a polytetrafluoroethylene fiber. According to the invention, the yarn is formed by intertwining the antibiotic strand and the flame-retardant strand, the antibiotic strand is formed by blending the nanometer titanium dioxide catalyst fiber with the bamboo charcoal fiber, and the flame-retardant strand is formed by blending the PPT fiber with the polytetrafluoroethylene fiber, through compounding of the multiple fibers and configuration of the antibiotic coating, the heat insulation fibrous layer and the flame-retardant coating arranged on the surface layer, the yarn is enabled to have quite good antibiotic and flame retardation effects, the preparation cost of the yarn is low, the economic benefits are good, and large-scale production is facilitated.

Description

technical field [0001] The invention belongs to the field of textile production, and in particular relates to an antibacterial and flame-retardant yarn and a production process thereof. Background technique [0002] Yarn is a product processed from various textile fibers into a certain fineness, which is used for weaving, rope making, thread making, knitting and embroidery, etc. [0003] Yarn is divided into: ①Short fiber yarn, which is processed by spinning short fiber (natural short fiber or chemical fiber cut fiber), and is divided into ring spinning, open end spinning, self-twisting yarn, etc. ② Continuous filaments, such as natural silk and chemical fiber filaments, are divided into twisted or untwisted, smooth filaments or deformed filaments, etc. ③Short fiber and continuous filament combined yarn, such as polyester-cotton filament core-spun yarn, etc. The thread is made of two or more single yarns combined and twisted. [0004] There are many classifications of yar...

Problems solved by technology

However, although the composite yarn provided by this patent is composed of a variety of fibers, its function is single, and it still only has the characteristics of flame retardancy, high temperature resistance, etc.
