Problems solved by technology

[0009] 3. Irregularization of cross section
In use, it is found that the fiber with such a four-leaf cross-section has poor bending resistance, and the relatively large two "leaves" are easy to wrinkle and break, and the anti-bending rebound performance is not good. Clothes made of this fiber After twisting or double twisting, the clothes are easy to deform
[0013] Over the years, people have been trying to combine antimicrobial properties and profiled cross-sections to produce a special-shaped polyester fiber with antimicrobial properties and good bending and rebound resistance, but the effect has not been good.

Abstract

The invention relates to four-leaf shape polyester fiber or filament with both antibiosis function, moisture absorption and sweat discharging function, in particular to the polyester fiber or filament with the following characteristics that the fiber or filament contains 3 to 20 permillages of nanometer silver powder in dried weight, the cross section of which is four oval blades with corrugated edges, and the four oval blades have the same size and vertically balanced; the ratio between the width B of the oval blades and the distance A between the two mutually balanced oval blades is 1:3 to 1:20. The polyester fiber provided by the invention combines the advantages of antibiosis and non conventional type cross section, which has the effects of antibiosis and deodorization, moisture absorption and rapid drying, portability and comfortability, and softness and body contact free. In addition, the shape of the cross section is unique, the ruffle is uneasy to be created during the using, the counter bending and rebounding performance is remarkable, and the wicking effect is better.

Description

technical field [0001] The present invention relates to a kind of quatrefoil polyester fiber or filament with antibacterial and moisture absorption and perspiration functions, more specifically relates to such a kind of fiber or filament, containing 3‰-20‰ nano-scale silver source powder, its The cross section has 4 ruffle-edged oval leaves of equal size. Background technique [0002] We are surrounded by all kinds of microbes that, in some cases, can interfere with our ability to live healthy lives. Microorganisms that exist in our clothes are able to proliferate rapidly due to the favorable conditions provided such as temperature, humidity and various nutrients. Accordingly, there is a continuing desire to provide fibers with antimicrobial activity to protect the user while doing so economically. [0003] In chemical fiber products, polyester fiber has been the largest synthetic fiber produced and consumed for many years. Antimicrobial polyester fibers have been propose...
