( Spun-bonded non-woven unique advantages make it a vast market! ]

Since plastic limit order issued, spun-bonded non-woven up against the white pollution environmental protection guard roles. Although China's spun-bonded non-woven industry developing rapidly, but compared with international advanced spinning melt industry, there are quite a gap. Therefore, although spun-bonded non-woven has broad market prospects, but the industry still needs to be adjusted. Spun-bonded non-woven fabric: is in polymer has been after extrusion, stretching, constitute the continuous filament, filament laid into the net, fiber network course itself again glue, hot glue, chemical bonding or dull consolidate oral, make the fabric non-woven fabrics. Spun-bonded non-woven advantage: high strength, good resistance to high temperature efficiency ( Persistent application in 150 ℃ condition) , ageing resistance, resistance to ultraviolet radiation, high stretch rate, good strength, air permeability and so on, corruption resistance, sound insulation, moth-proofing, non-toxic. Spun-bonded non-woven main USES the main products are polypropylene spun-bonded nonwoven cloth, polyester ( Filament and staple fibers) The most common and most commonly used to us is the application of non-woven bags, non-woven packaging, etc, but also easy to recognize, because of spun-bonded non-woven fabric mill is the diamond. Application level can also do the flower packing cloth, cloth bags, and so on, wear resistance, strong feel is good, and so on characteristics, make him the best way to make this kind of product. Polymer (spun-bonded non-woven process Polypropylene material + back) — — Big screw stem, high temperature melting - — Filter - — Metering pump ( Quantitative delivery) — — Spinning ( Spinning entrance and stretching suction) — — Cooling - — Airflow traction - — Net curtain into net - — Up and down roller ( Pre-reinforcement) — — Hot rolling mill ( Reinforcement) — — Winding - — Pour the cloth cutting - — Weighing and packing - — Finishing warehousing spun-bonded non-woven technology type spun-bonded non-woven technology in the world are mainly Germany phil's Finn lecco, Italy's STP, Japan kobe steel technology, etc. The current situation, especially to lai Finn technology to become the mainstream technology in the world. At present has developed to the fourth generation technology. Characterized by using ultra-high speed negative pressure air draft, fiber can be stretched to around 1 but Neil. There has been a lot of domestic enterprises for the generic, because of its core technology has many frontier problems unsolved or master, domestic equipment manufacturing enterprises want to achieve, it will take time for the Finn technology level.
