Embodiment 1

[0016] This embodiment provides a kind of women's underwear, including trouser body and crotch, described crotch is made up of inner layer and outer layer, and described inner layer and outer layer are respectively made of pure polylactic acid fiber underwear underwear fabric, The pure polylactic acid fiber underwear fabric is knitted or woven with 75D-150D polylactic acid fiber DTY filament and 30D-75D polylactic acid fiber FDY filament. The above-mentioned DTY polylactic acid fiber filament is formed by spinning, and its specific steps include POY and DTY. The process route of POY is: screw extruder → pre-filter → static mixer → metering pump → spinning assembly → Spinning → blowing and oiling → tunnel → POY winding yarn; among them: melt spinning temperature: 200-220°C; blowing conditions: wind speed 0.2-0.5m / s, wind temperature 25-30°C, relative humidity 60-75 %; the oiling rate is 0.70-1.20%; the spinning speed is 3500-5500m / min; the DTY production process route is: yarn ...

Abstract

The invention relates to pure polylactic acid fiber underwear shell fabric, and belongs to the technical field of textile. The problem that in the prior art, 100% pure spinning of polylactic acid fibers can not be achieved is solved. The pure polylactic acid fiber underwear shell fabric is formed by spinning 100% pure polylactic acid fibers, and the shell fabric is formed by weaving 50-150 D polylactic acid fibers DTY filaments and 30-75 D polylactic acid fibers FDY filaments. The pure polylactic acid fiber underwear shell fabric has the following advantages that the shell fabric is made of the 100% pure polylactic acid fibers and has the advantages of pure natural bacteriostasis and the non-sensitization effect, the plant source fibers have the life cultivation and health preservation functions such as smoothness, breathability, sweat drainage, itching relieving, bacteria resistance, bacteriostasis and skin-friendly and skin care performance, and the shell fabric has excellent stretch stability.

Description

technical field [0001] The invention belongs to the technical field of textiles, and relates to a polylactic acid fiber fabric, in particular to a pure polylactic acid fiber underwear underwear fabric. Background technique [0002] In modern society, with the continuous improvement of people's material living standards, people pay more attention to their health status. In life, some common skin diseases, urinary system diseases, female reproductive system diseases, etc. often plague people. Most diseases relapse after treatment and persist for a long time. A large part of these reasons are caused by the poor air permeability, poor hygroscopicity and allergenic fabrics used in underwear underwear. Therefore, the current selection of underwear fabrics requires that they meet the standards of natural ecology, smoothness and breathability, moisture absorption and perspiration, antibacterial and antibacterial. [0003] Corn fiber (polylactic acid PLA fiber) is a synthetic fiber...
