Polypropylene non woven fabric is the most common and common fabric in the non-woven classification. The process is simple, the output is large, the cost is low, and the use is wide. It is a new generation of environmentally friendly materials, which is reflected in all aspects of life. Let's get to know it together.
1. What is polypropylene non woven fabric?
Polypropylene spunbond non woven fabric, also known as polypropylene non-woven fabric, polypropylene non-woven fabric, is a new generation of environmentally friendly materials, with the characteristics of water repellency, breathability, flexibility, non-combustion, non-toxic and non-irritating, and rich colors. 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. . There is also a kind of using pp polypropylene as raw material, which is polymerized into a mesh by high temperature drawing, and then bonded into cloth by hot rolling. Because the technological process is simple, the output is large, and it is non-toxic and harmless to the human body. Therefore, it is widely used in various fields such as medical and sanitary non-woven fabrics, agricultural non-woven fabrics, industrial non-woven fabrics, and non-woven fabrics for packaging materials.
2. What is the raw material of Polypropylene non woven fabric?
Polypropylene is a kind of polymer commonly used in the spun-web process. It is a high-quality raw material for polypropylene spunbond non-woven fabrics. 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. The structural formula of polypropylene is that in the polymerization process, three configurations of polymers can be produced due to the different positions of the methyl groups in the three-dimensional space.
3. The main purpose of polypropylene non woven fabric?
Polypropylene spunbond non woven fabric is mainly used in medical hygiene materials, agricultural coverings, home textiles and household products, packaging materials, shopping bags, etc. New products emerge in an endless stream and are widely used.
10~40gsm for medical and health products, such as masks, medical disposable isolation gowns, head covers, shoe covers, diapers, adult incontinence and hygiene products, etc.; 17~100gsm (3% UV) for agricultural coverage, such as crop coverage Quilts, root control bags, seed bags, weeding mats, nursery protective covers, insulation curtains, ground protection, etc.; 15~85gsm for home textile linings, such as sofa linings, mattress spring bags, furniture linings, disposable bed sheets, Pillowcases, house plumbing packing materials, roofing and tile underlayment, soundproof ceilings, floor mat composites, insulating materials, etc.; 40~120gsm for household items such as wardrobes, storage boxes, tablecloths, dust covers, wallpapers, calendars, etc. ; 50~120gsm for packaging materials, such as shopping bags, suit sets, gift bags, tea bags, rice flour bags, flower material packaging, etc.; 100~150gsm for blinds, car interiors, photography background cloth, advertising cloth, etc.
Polypropylene non woven fabric is a multi-functional product with wide application, environmental protection and low price. It has been effectively developed and mass-produced in my country in recent years, especially in epidemic prevention work. It has played a huge role in the history of non woven fabrics.
