Non-woven fabrics are a new non-woven fabric industry in recent years, are applied to various industries, particularly are used in the industries of facial masks, sanitary towels, paper diapers, paper towels, toilet paper, masks and the like,
the first generation of non-woven fabric product is a chemical bonding method web-forming production process, the cost is low, the market demand is huge, the non-woven fabric raw materials are all chemical fibers, viscose fibers and synthetic artificial fibers, when the chemical bonding method production process is adopted for manufacturing, the non-woven fabric contains partial chemical substance residues, and certain harmfulness is generated to human health!
Such as sanitary napkins, paper diapers and other products, cause skin allergy and irritation of human bodies, the sanitary napkins cause a large number of gynecological diseases of women, and the diapers for children cause 'red buttocks' … … after irritating the skin
The second generation non-woven fabric is upgraded into a needle punching production process, the defect of chemical pollution residue is overcome compared with the first generation non-woven fabric adopting a chemical bonding method, metal needles rub at a high speed in the production process to generate strong static electricity, and a large amount of chemical antistatic agent is used in the production process, so that the non-woven fabric still has certain harm to human bodies;
natural silk is composed of animal active protein and 18 amino acids, and is known as 'the second skin of human body'! The inner layer skin-attached fabric used as the mask has good skin-friendly property and skin-attaching property. The silk fiber has the functions of natural bacteriostasis, antibacterial function and antianaphylaxis. Good air permeability! Comfort of moisture preservation and moisture release! The raw material of the mask silk spunlace non-woven fabric is produced by adopting the silk raw material produced by the neutral protease degumming and silk drawing technology invented by the Liaoning Zhongtian silkworm industry science and technology company, and the most advanced and environment-friendly spunlace process of Germany is selected to produce the non-woven silk spunlace non-woven fabric. Environmental protection original ecology! Is a product for upgrading the new development of the big health industry;
