Embodiment 1

[0040] An antibacterial and anti-mite blended non-woven fabric based on polylactic acid fibers. The blended non-woven fabric is made of the following raw materials in parts by weight: 90 parts of polylactic acid fibers and 10 parts of absorbent cotton. The specific preparation process includes the following steps:

[0041] Step 1: First, prepare raw materials for polylactic acid fiber and absorbent cotton. Antioxidants, dispersants and softeners are also mixed in the raw materials to remove pollution and fiber raw materials containing impurities exceeding the standard, and then wash with water to remove impurities and decompress Drying, during decompression drying, the pressure is controlled at 1500pa, and the temperature is controlled at 55°C;

[0042] Step 2: Add the prepared polylactic acid fiber and absorbent cotton to the disc bale machine, which is used to open the polylactic acid fiber and absorbent cotton and transport them to the multi-compartment blender;

Abstract

The invention discloses an antibacterial and anti-mite blended non-woven fabric based on polylactic acid fibers. The blended non-woven fabric is prepared by mixing the polylactic acid fibers with absorbent cotton. The specific preparation process comprises the following steps: preparing raw materials; feeding the the raw materials into a disc plucker; feeding the raw materials into a multi-bin cotton mixer; feeding the raw materials into a finishing machine; feeding the raw materials into a carding machine; feeding the raw materials into a cross lapping machine; feeding the raw materials intoa fiber drafting machine; carrying out spunlace treatment; feeding the raw materials into a coiling machine; carrying out drying treatment; feeding the raw materials into a splitting machine; and packaging and warehousing. The problem that an existing all-cotton spunlaced non-woven fabric does not have natural antibacterial and anti-mite effects is solved, and after a certain proportion of polylactic acid fibers are blended in all-cotton, the natural antibacterial and anti-mite characteristics of the polylactic acid fibers are utilized, so that the blended non-woven fabric also has the naturalantibacterial and anti-mite functions.

Description

technical field [0001] The invention belongs to the field of non-woven fabrics, in particular to an antibacterial and anti-mite blended non-woven fabric based on polylactic acid fibers. Background technique [0002] With the development of science and technology and the progress of the non-woven fabric industry, the variety of non-woven fabrics has continued to increase, and its application range has expanded from people's daily life to industry, agriculture, transportation, military, health and many other fields. [0003] All-cotton spunlace non-woven fabric is a fabric that does not require interweaving of warp and weft, which is formed by combing natural cotton fibers, laying the net, and reinforcing them with water under a certain pressure; all-cotton spunlace non-woven fabrics have the natural softness and non-toxicity of natural cotton fibers Stimulating, environmentally friendly, easy to degrade, renewable, easy to absorb water, and skin-friendly. [0004] Polylactic...
