Abstract

The invention provides an environment-friendly anti-mite non-woven fabric and a preparation method thereof, and belongs to the technical field of non-woven fabrics. The environment-friendly anti-mite non-woven fabric is prepared from anti-mite modified polypropylene master batches, bamboo charcoal fibers, an antioxidant and an ethylene-propylene copolymer; the anti-mite modified polypropylene master batches are prepared by mixing and granulating an immobilized anti-mite agent and polypropylene; the immobilized anti-mite agent is characterized in that an anti-mite agent is coated in a chitosan-asiatic acid compounded cage-shaped structure; and the anti-mite agent is selected from at least one of borneol, isoborneol, ethyl thiocyanate, crude persimmon tannin and eucalyptus oil. The non-woven fabric is degradable, has good anti-mite, antibacterial and bacteriostatic effects, and is easy to degrade and environment-friendly. Meanwhile, the non-woven fabric has a wide application field, and can be used in anti-mite breeding textiles such as masks, clothes, sofas and the like.

Description

technical field [0001] The invention relates to the technical field of nonwoven fabrics, in particular to an environment-friendly anti-mite nonwoven fabric and a preparation method thereof. Background technique [0002] Non-woven fabric, also known as non-woven fabric, is composed of directional or random fibers. It is a new generation of environmentally friendly materials with the characteristics of moisture resistance, breathability, and flexibility. The existing non-woven fabrics mostly use polypropylene (pp material) pellets as raw materials, which are produced by continuous one-step process of high-temperature melting, spinning, laying, and hot-pressing coiling. In addition, since the non-woven fabric uses polypropylene resin as the main raw material, the specific gravity of the polypropylene resin is only 0.9, which is only three-fifths of that of cotton. Therefore, the non-woven fabric also has the advantages of bulkiness and good hand feeling. At the same time, non-...
