Abstract
The invention relates to an environmental-friendly and sanitary product. The environmental-friendly and sanitary product comprises a surface layer and a bottom layer which are in contact with skin, wherein the surface layer is made from natural-silk non-woven fabrics, and the bottom layer is made from degradable films; the raw material formula of the degradable films contains the following ingredients in percentage by weight: 5-10% of calcium carbonate, 1-3% of titanium white, 50-70% of starch and 20-40% of low-density polyethylene. According to the environmental-friendly and sanitary product, the degradable films are adopted as the bottom layer, and the natural-silk non-woven fabrics are adopted as the surface layer, so that when the environmental-friendly and sanitary product is buried in soil, both the surface layer and the bottom layer can be degraded in one year, the pollution to the environment can not be caused, and the degradable films have good moisture permeability and gas permeability.
Description
Technical field
the present invention relates to a kind of environmentally-friendly sanitary articles for use.
Background technology
at present, the top layer of hygienic article contact skin adopts containing the PE material of plastic components or the nonwoven cloth material that the raw materials of chemical fibres are made.Notification number is CN1069706C, the day for announcing is pretreating process and the goods thereof of the cocoon fiber in August 15 calendar year 2001, it discloses these goods and can be used for hygienic article, but in the preparation, in the formula of degumming liquid, contains Caustic soda, and Caustic soda has severe corrosive, in addition, facts have proved the silkworm silk non-woven fabrics of 100% silkworm silk that employing the method prepares, its water absorption, water penetration are all bad, cannot be for the top layer of hygienic article.
at present, the bottom of hygienic article is adopted ventilated membrane made of plastic more, and this ventilated membrane is embedded in and in soil, needs ability degraded in 250 years, therefore will cause a large amount of pollutions, and earth environment is carried out to heavy damage.
