Non-woven fabric is a kind of fabric that does not need to be spun and weaves, which just oriented or randomly arranged woven short fibers or filaments to form a web structure, which is then reinforced by mechanical, thermal bonding, or chemical methods. It is called cloth because of its appearance and certain properties.
PP spunbond nonwoven cloth, also called polypropylene spunbond non-woven fabric, is a new generation of environmentally friendly materials, which has the characteristics of water repellency, breathability, flexibility, non-combustibility, non-toxic, non-irritating, rich colors, and so on. If the material is naturally decomposed outdoors, the longest service life is 90 days. If it is decomposed indoors within 8 years, it is non-toxic, tasteless, and free of any residual substances during combustion, which will not pollute the environment. Therefore, environmental protection comes from this.
PP spunbond nonwoven cloth is a kind of non-woven fabric. It is a kind of non-woven fabric, which is made of PP polypropylene by high-temperature drawing polymerization, and then bonded into cloth by the hot-rolled method. 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 medical sanitary materials, agricultural non-woven fabrics, industrial non-woven fabrics, and non-woven fabrics for packaging materials.
Polypropylene is a polymer commonly used in the spinning process. The main performance parameters are isotacticity, melt index (MFI), and ash. The spinning process requires that the isotacticity of polypropylene is above 95%, and spinning is difficult if it is less than 90%.
New products using pp spunbond nonwoven cloth as raw materials emerge endlessly and have a wide range of uses. The pp spunbond nonwoven cloth mainly has the following functions.
1. It is used in medical and sanitary products, such as masks, disposable medical isolation gowns, headgear, shoe covers, diapers, adult urinary incontinence, sanitary products, and so on.
2. It is used for agricultural mulch, such as crop cover, root control bag, seed bag, weeding mat, nursery protective cover, insulation curtain, ground protection, and so on.
