Problems solved by technology

[0002] Because non-woven fabrics (Non-woven, also known as non-woven fabrics) have better material properties than traditional fabrics, and the production process is more streamlined, from raw materials to finished products in one go, without having to go through tedious processing like traditional fabrics process, so it can save production time and production costs. Non-woven fabrics have the characteristics of light weight, high air permeability, moisture absorption, moisture retention and dust resistance, so they have been widely used in agriculture, construction, people's livelihood, industry, medicine, transportation and other industries. Among them, especially in the past 10 years, using the water absorption and waterproof properties of non-woven fabrics to make fabrics and clothes with moisture absorption and perspiration has become the mainstream. The water-absorbing layer made of absorbent polyester fiber non-woven fabric, Rayon fiber non-woven fabric, natural cotton cloth, natural linen and other materials is combined with a waterproof layer made of a layer of waterproof polyethylene fiber. There are two ways of production. The first one is to use glue to bond the water-absorbing layer non-woven fabric made of one of the aforementioned materials and the polyethylene waterproof layer non-woven fabric. The disadvantages of this method are: There will be an adhesive film layer between the water-absorbing layer and the waterproof layer, which will affect the performance of the overall non-woven fabric's water-absorbing or air-permeable properties; After the non-woven fabrics of the waterproof layer are stacked, they are combined with each other by sewing or hot glue on the periphery. The disadvantage of this method is that there will be slippage between the non-woven fabric of the water-absorbing layer and the non-woven fabric of the waterproof layer, which will make In addition to its insufficient mechanical strength, it is more likely to cause continuous sliding during the friction process and cause damage. In addition, since the raw materials of artificial fibers such as polyester fibers or polyethylene fibers are highly dependent on petroleum and its derivatives, Therefore, it is easy to generate high carbon emissions in the production process, resulting in the accumulation of greenhouse gases, and petroleum resources are not inexhaustible raw materials. After use, man-made fibers such as polyester fibers or polyethylene fibers are also Can not be decomposed naturally, but will cause secondary pollution to the environment
