PP Spunbond Nonwoven Fabric High Tensile Strength

Yiwu Guanghong Non-Woven Co.,Ltd | Updated: Oct 16, 2017

I believe a lot of friends are not familiar with pe/pp two-group spunbonded fabric, pe/pp Two-group spunbonded fabric is made of PE polyethylene and PP polypropylene by spunbonded method, PP Spunbond Nonwoven Fabric and has a double-layer skin core structure. Because different from the traditional pp spunbonded fabric and hot-air cloth, pe/pp Two-group spunbonded fabric with soft touch smooth, hot bonding, high tensile strength, safety without adding no stimulation and other characteristics

Now the awareness of national security is improving, consumers in the purchase of diapers on the safety of higher requirements. Then in the actual production and sale of diaper, it is necessary to have a better safety.

PE/PP two-part fiber is the core-type composite structure, PP Spunbond Nonwoven Fabric the core material is polypropylene (PP) (melting point of 165 ℃), the cortical material is polyethylene (PE) (melting point of 130 ℃ or so). When the hot rolling is melted, the lower temperature is used, the cortex melts and bonding, and the core properties remain unchanged. When bonding with glue, the effect is not so good as to destroy the adhesive, which can prevent the compound delamination and prevent the creep of rubber. No need to add softener, PP Spunbond Nonwoven Fabric smooth agent, elastomer and other auxiliaries.

The characteristics of additive-free additives in the production process of pe/pp two-part spunbonded fabrics just fit the safety requirement of diaper. In the diaper storage process, PP Spunbond Nonwoven Fabric no additives precipitation, will not affect the adhesion of hot melts.

spunbonded nonwoven production using raw materials for high melt index polypropylene, and calcium carbonate filler masterbatch mixed evenly, from the hopper into the screw extruder extrusion melt into a continuous pre-filter, and then into the spinning box. Melt through metering pump into the spinning head, PP Spunbond Nonwoven Fabric by metering pump accurate measurement, the melt quantitative transfer to the Spinneret, and through the Spinneret hole to form a continuous melt fine flow, that is, the primary fiber. PP Spunbond Nonwoven Fabric The primary fiber is then cooled by a sudden cold wind and the air is stretched to form a filament bundle. Long silk beam by swinging roller reciprocating swing, evenly on the floor in the operation of the network to form a network curtain.

Non-woven fabric in the process of general selection of fillers are mainly calcium carbonate, the production process appropriate add a little old soil or wollastonite increased dispersibility and transparency. PP Spunbond Nonwoven Fabric The general choice of calcium carbonate mesh in more than 1500 mesh, also can not be too fine, because the price is too high, the other ultrafine powder generally dispersed.
