Spunbond non-woven fabric, also known as polypropylene spunbond non-woven cloth, is a new generation of environmentally friendly materials, which is waterproof, breathable, flexible, non-combustible, non-toxic and non-irritating, and rich in color. If the material is placed outdoors and decomposed naturally, its longest life is only 90 days, and it will decompose within 8 years when placed indoors. It is non-toxic, odorless, and free of any residual substances when burning, so it does not pollute the environment, so environmental protection comes from this.
Polypropylene spunbond non-woven cloth is a kind of non-woven fabric, which is made of pp polypropylene as raw material, polymerized into a network by high temperature drawing, and then bonded into a cloth by hot rolling.Due to the simple process, large output and non-toxic and harmless to human body, polypropylene spunbond non-woven cloth are widely used in medical and sanitary material non-woven fabrics, agricultural non-woven fabrics, industrial non-woven fabrics, and non-woven fabrics for packaging materials.
Polypropylene kitchen wipes material is a kind of polymer commonly used in the spinning process, and the main performance parameters are isotacticity, melt index (MFI) and ash content.The spinning process requires the isotacticity of polypropylene to be above 95%, and if it is less than 90%, spinning is difficult. During the polymerization process, three configurations of polymers can be produced due to the different positions of the methyl groups in the steric space.
