In today’s society, there are many common non-woven fabrics in various industries, such as PP polypropylene spunbond non-woven fabrics. Spun fabric is a commonly used one.
China’s polypropylene (PP) industry has developed rapidly in the past 10 to 15 years, with annual production capacity increasing from less than 4 million tons in 2002 to 16.88 million tons in 2014, and the rapid growth in production capacity in the next few years will be even greater. It will promote China to replace the United States as the world’s largest polypropylene producer. As early as 2008, China’s polypropylene production capacity accounted for 14% of the world’s total production capacity. From 2009 to 2012, China’s polypropylene production capacity increased at a rate of approximately 1 million tons/year. It is expected that by 2015, China’s polypropylene production capacity will expand to more than 1,800 tons. Thousands of tons.
PP polypropylene spunbond non-woven fabric has good heat resistance, with a melting point of 164~170℃, and the products can be sterilized at temperatures above 100℃. It will not deform at 150℃ without being affected by external force. The embrittlement temperature is -35°C. Embrittlement will occur below -35°C, and the heat resistance is not as good as PE. It also has good chemical stability. In addition to being corroded by acids, it is relatively stable to various other chemical reagents. However, low molecular weight aliphatic hydrocarbons, aromatic hydrocarbons, etc. can soften and swell non-woven fabrics. The chemical stability varies with the degree of crystallinity. The increase has also improved.
