Problems solved by technology

[0005] In existing patents and documents, when preparing anti-mite microcapsules, the wall materials used are mostly polymers such as urea-formaldehyde resin, methyl methacrylate, polyurethane, and polyamide. The preparation process is relatively complicated, and the used formaldehyde, acid chloride The toxicity is also relatively high, especially the strength of these organic wall materials is not high, so that the microcapsule drug is easily broken during the finishing process and the drug is released, failing to achieve the effect of protecting the drug and drug sustained release
Among the anti-mite agents currently used, many drugs are highly toxic to the human body and irritating to the skin, which is not conducive to environmental protection and human health.
In addition, although the anti-mite drug is prepared into microcapsules and finished on the fabric, the weak binding force between the microcapsule and the fabric makes it not resistant to washing, which eventually leads to poor anti-mite durability of the fabric, which is also a significant deficiency in the preparation of anti-mite fabrics by post-finishing methods.

Abstract

The invention relates to the technical field of fabric manufacturing, and discloses a method for preparing a mite-preventing fabric. The method comprises the steps that firstly, CaCO3 is adopted as a wall material, mite-preventing medicine is adopted as a core material, and mite-preventing microcapsules covered with CaCO3 are prepared; then mite-preventing finishing liquid is prepared, and contains the mite-preventing microcapsules and a waterborne polyurethane adhesive; finally, a fabric is soaked in the mite-preventing finishing liquid, and the mite-preventing fabric is obtained after drying. The mite-preventing microcapsules prepared from CaCO3 as the wall material are free of toxins and high in strength, the situation that the mite-preventing microcapsules are broken in the finishing process, and consequently the medicine is released and leaked is not prone to happen, and the good medicine slow release effect is achieved. When the mite-preventing finishing liquid is prepared, the waterborne polyurethane adhesive is added, the bonding force of the mite-preventing microcapsules and the fabric is improved, and therefore the mite-preventing durability of the fabric is remarkably improved. The selected mite-preventing medicine has the good mite resisting effect, and is low in toxicity to the human body and small in skin irritation. The method can be widely applied to various fabrics prepared from natural fibers or synthetic fibers.

Description

technical field [0001] The invention relates to the technical field of fabric manufacturing, in particular to a preparation method of an anti-mite fabric. Background technique [0002] Dust mites are tiny arthropods invisible to the naked eye. They are widely distributed in household textiles such as clothing, bedding, carpets, cushions, and plush toys, and mainly feed on human dander. Dust mites not only transmit bacteria and viruses themselves, but also their secretions, metabolites and dead insects are strong allergens, which can cause allergic rhinitis, infant eczema and chronic urticaria, and even cause bronchial urticaria in severe cases. diseases such as asthma. Since mites mainly live in household textiles, the preparation of anti-mite fibers and fabrics has gradually attracted the attention of academia and industry. [0003] At present, the preparation methods of anti-mite fiber fabrics mainly include three methods: fabric finishing method, functional fiber method...
