Problems solved by technology

Although the PTT fiber prepared by this method has antibacterial properties, silver nitrate is relatively serious to environmental pollution, the price is high, and the manufacturing process is cumbersome, and the PTT fiber obtained has a single function and does not have the function of preventing ultraviolet radiation.
[0005] At present, there have been researches on the functional modification of PTT fibers or filaments at home and abroad, but the modification methods are expensive, environmentally friendly, cumbersome, and functional; there are also studies on attapulgite in material adsorption and catalysis However, there have been no reports on the functional modification of textiles using nano-scale attapulgite particles.

Abstract

The invention provides antibacterial ultraviolet-preventing PTT filaments and a preparation method thereof. According to the invention, PTT and nano-grade attapulgite particles are adopted as main raw materials; PTT filament plasma etching is carried out, the nano-grade attapulgite particles are grafted; or PTT slices and nano-grade attapulgite particles are subjected to blending and melt spinning, such that the filaments are obtained. With the method, the attapulgite particles with antibacterial ultraviolet-preventing dual effects are introduced into the PTT filaments. As a result of tests, the PTT filaments provided by the invention have performances of good elasticity and comfortable wearing of common PTT filaments, and have good antibacterial ultraviolet-preventing double-effect functions. A transmittance of the filaments to ultraviolet light with wavelength lower than 320nm approaches zero. The filaments have a UPF value ??range of 200-500, an Escherichia coli inhibition rate of 80-90%, and a staphylococcus aureus inhibition rate of 78-90%.

Description

technical field [0001] The invention relates to a PTT filament and a preparation method thereof, in particular to an antibacterial and ultraviolet-proof PTT filament and a preparation method thereof. Background technique [0002] PTT is the abbreviation of polyethylene terephthalate (polytrimethylene terephthalate), which has good tensile and compression elasticity, wear resistance, moisture absorption and curling properties, and is soft to the touch, and the price is much lower than that of spandex filament. An ideal high elastic textile. [0003] With the progress of society, people have higher and higher requirements for the health and safety of textiles in recent years, and textiles with good anti-ultraviolet radiation and antibacterial properties are increasingly favored by consumers. At present, the modification of textiles with functional nanoparticles (titanium dioxide, zinc oxide, magnesium oxide, chitosan, nano-silver and natural clay materials) is an important me...
