preparation example Construction

[0045] The preparation method of the modified medical stone fiber is as follows: the medical stone fiber is added to a sodium stearate solution with a mass fraction of 35%, and at the same time, carbon dioxide is introduced to adjust the pH of the solution to be 6, and the reaction temperature is controlled to be 120° C. , the reaction time is 30min, after filtering and drying, the modified medical stone fiber is obtained.

[0046] In a preferred embodiment, the weight ratio of the medical stone fiber to sodium stearate is 1: (1-3).

[0047] In this application, the "nano diatomite" is commercially available and purchased from Jilin Province Tianyuan Catalyst Co., Ltd.

[0048] In this application, the "nano silicon dioxide" is commercially available and purchased from Nanjing Xianfeng Nano Materials Co., Ltd.

[0049] The "nano silicon dioxide" is nano silicon dioxide treated with KH550.

[0050] The CAS number of the nano silica product treated with KH550: 7631-86-9.

Abstract

The invention relates to the technical field of new textile materials, in particular to novel polylactic acid fibers as well as a preparation method and application thereof. The novel polylactic acidfibers are at least prepared from the following preparation raw material components: 60-80 parts of polylactic acid; 5-15 parts of bio-based natural fibers, 3-15 parts of cellulose acetate, 1-5 partsof cyclodextrin, 0.1-1 part of medical stone, 1-3 parts of nano-diatomite and 1-2 parts of nano-silica.

Description

technical field [0001] The invention relates to the technical field of new textile materials, in particular to a novel polylactic acid fiber and its preparation method and application. Background technique [0002] With the improvement of living standards, people have abandoned the concept of clothing only for shame and warmth, and began to develop in the direction of health, environmental protection, fashion, comfort and functionality. Traditional cotton, linen, silk wool and petroleum-based synthetic chemical fibers can no longer meet the raw material requirements of modern clothing. The development of green environmental protection fiber and natural functional fabrics has become a research hotspot. [0003] In recent years, elastic fabric clothing has been increasingly widely used in the market because of its excellent elasticity, body attachment, and good self-cultivation effect. Especially elastic underwear and sportswear, the fabric is close to the skin, and the quali...
