Polypropylene spunbond non-woven fabric
If the material is placed outdoors and decomposed naturally, its longest life span is only 90 days, and it decomposes within 8 years when placed indoors. It is non-toxic, odorless and has no leftover substances when burned, so it does not pollute the environment, so environmental protection is therefore Come.
PP spunbond non-woven fabric is a kind of non-woven fabric, which is made of pp polypropylene as raw material, which is polymerized into a net through high temperature drawing, and then bonded into a fabric by hot rolling.
Due to the simple process flow and large output, it is non-toxic and harmless to the human body. Therefore, it is widely used in various fields such as non-woven fabrics for medical and sanitary materials, non-woven fabrics for agriculture, non-woven fabrics for industrial use, and non-woven fabrics for packaging materials.
1. Polypropylene material
Polypropylene is a polymer commonly used in the spinning process. 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 spinning is difficult if it is less than 90%.
During the polymerization process, because of the different positions of the methyl groups in the three-dimensional space, three types of polymers can be produced.
Material: 100% polypropylene fiber
Processing method: Spunbond method
Width: 160/180/220/240/260/320cm (special width can be cut according to different requirements)
Color: Normally according to the color card provided by the factory, or special color according to customer requirements (Pantone card can do it)
Grain: small hole dot/sesame dot/cross pattern/special pattern (most of the small hole dot patterns on the market, sesame dots are mostly used for sanitary materials, cross pattern is used for shoe materials and packaging, and there are fewer word patterns. )
Features: It is a new generation of environmentally friendly materials, which are moisture-proof, breathable, flexible, light weight, non-combustible, easy to decompose, non-toxic and non-irritating, recyclable, soluble, waterproof, dustproof, anti-ultraviolet, and color Abundant, low price, recyclable and other characteristics.
2. Purpose
Spunbond non-woven fabrics are mainly used in medical sanitary materials, agricultural coverings, home textiles and household products, packaging materials, shopping bags, etc. New products are emerging in endlessly and have a wide range of uses.
Such as masks, disposable medical isolation gowns, hoods, shoe covers, diapers, adult urinary incontinence and hygiene products, etc.
17~100gsm (3% UV) for agricultural coverage
15~85gsm for home textile lining
40~120gsm for household products
50~120gsm for packaging materials
100~150gsm is used for blinds, car interiors, photographic background cloth, advertising cloth, etc.
