Characteristics of non-woven polypropylene filter cloth

Polypropylene is the trade name of polypropylene fiber. It is a fiber made from propylene as a raw material through polymerization and melt spinning. Non-woven polypropylene filter cloth is a non-woven filter cloth mainly made of polypropylene. It is a melt-spun fiber with excellent acid and alkali resistance. Let's talk about the specific aspects of polypropylene filter cloth performance. 1. Non-woven polypropylene filter cloth use: beneficiation, manufacturing, smelting, pharmacy, ceramics, chemical work filter bottom 2. Non-woven polypropylene filter cloth filtration performance: industrial fabric made of polypropylene long fiber, smooth cloth surface , Good air permeability. Polypropylene staple fiber woven industrial cloth, cloth surface with hairy. The effect of powder filtration and pressure filtration are better than that of long fiber. Polypropylene long fiber has long fiber. The formed yarn is smooth. Polypropylene staple fiber, short fiber, spun yarn ribbon hair. 3. Classification of non-woven polypropylene filter cloth filter cloth: polypropylene staple fiber filter cloth; polypropylene long fiber filter cloth. 4. Polypropylene filter cloth material properties: melting point (℃): 165-173. Proportion: O.9l. Breaking strength (g/d): 4.5-9. Softening point (℃): 140-160. Heat resistance: slightly shrink at 90°C. Elongation at break (%): 18-35. It has good alkali resistance, acid resistance, abrasion resistance, good electrical conductivity, slightly better recovery than polyester, and poor corrosion resistance. Polypropylene was officially industrialized in 1957 and is a rising star among many synthetic fibers. Due to the simple production process of polypropylene filter cloth, low price, wide use, and high strength, polypropylene filter cloth has developed rapidly. The above is the detailed content of the characteristics of non-woven polypropylene filter cloth.
