Polypropylene spunbond non woven fabric is the most common fabric in the classification of non woven fabrics. It is a new generation of environmental protection material with simple process, large output, low cost and wide application, which is reflected in all aspects of life. Next, let's understand.
Polypropylene spunbond non woven fabric, also known as polypropylene non woven fabric, is a new generation of environmental protection material, which is waterproof, breathable, flexible, non combustible, non-toxic, non irritating and rich in color. If the material decomposes naturally outdoors, its longest service life is only 90 days. If it decomposes indoors for 8 years, the combustion is non-toxic. insipidness. There is no residual material, so it does not pollute the environment, so it is environmental protection. The other is PP polypropylene as raw material, which is polymerized into a net by high-temperature drawing, and then bonded into a cloth by hot rolling. Because the process flow is simple, the output is large, and it is non-toxic and harmless to human body. Therefore, it is widely used in medical and health materials non woven fabrics. Agricultural non woven fabrics. Industrial non woven fabrics. Non woven fabrics for packaging materials.
Polypropylene is a kind of polymer commonly used in spinning process. It is a high-quality raw material of polypropylene spunbond non woven fabric, and its main performance parameters are the same. Melting index (MFI) and ash. The grade specification of polypropylene is required to be more than 95% in spinning net technology. If it is less than 90%, it is difficult to spin. The structure of polypropylene is that in the process of polymerization, due to the different positions of methyl groups in three-dimensional space, three polymers can be produced.
Polypropylene spunbond non woven fabric is mainly used for medical and sanitary materials, agricultural coverage, home textiles and household products, packaging materials, shopping bags, etc. new products emerge in endlessly and are widely used. 10~40gsm is used for medical and health products such as masks, disposable medical isolation clothes, headgear, shoe covers, diapers, adult urinary incontinence, and health products. 17~100gsm (3% UV) is used for agricultural coverage, such as crop mulch, root control bags, seed bags, weeding mats, nursery protective covers, thermal curtains, ground protection, etc. 15~85gsm is used for home textile lining, such as sofa lining, mattress spring bag, furniture lining, disposable bed sheets, pillowcases, housing pipe packaging materials, roof and tile cushion, sound insulation ceiling, floor mat composite materials, insulation materials, etc.; 40~120gsm is used for household items, such as wardrobe, storage box, tablecloth, dust cover, wallpaper, calendar, etc; 50~120gsm is used for packaging materials, such as shopping bags, suits, gift bags, tea bags, rice flour bags, flower packaging, etc.
Polypropylene spunbond non woven fabric is a multi-functional product with wide use, environmental protection and low price. In recent years, it has been effectively developed and produced in large scale in China, especially in the work of epidemic prevention, which will be a rich color in the history of non woven fabrics.
