I believe many friends do not know much about PE / PP double group spunbond fabric. PE / PP double group spunbond fabric is made of PE polyethylene and PP polypropylene by spunbond method and has a double skin core structure. Because it is different from traditional PP Spunbond fabric and hot-air fabric, PE / PP double group spunbond fabric has the characteristics of soft feel, smooth touch, good thermal bonding, high tensile strength, safety, no addition and no stimulation!
Now the safety awareness of the whole people is improving, and consumers put forward higher requirements for safety when purchasing diapers. Then in the actual production and sales of diapers, it needs better safety of non-woven fabrics.
We all know that in order to achieve better softness in PP spunbonded nonwoven fabrics, various additives must be added. However, PE / PP two-component spunbond fabric can achieve better heat sealing and softness without any addition and modification.
The PE / PP bicomponent fiber is a skin core composite structure. The core material is polypropylene (PP) (melting point about 165 ℃), and the skin material is polyethylene (PE) (melting point about 130 ℃). When hot rolling and melting, the lower temperature is used, the outer layer melts and adheres, and the properties of the core layer remain unchanged. When bonding with the adhesive, the effect is not to damage the viscosity of the adhesive, and it can prevent compound delamination and rubber creep. No need to add softener, smooth agent, elastomer and other additives.
The characteristics of no additives in the production process of PE / PP two-component spunbond fabric just meet the safety requirements of diapers. During the storage of diapers, no additives are precipitated, which will not affect the adhesion of hot melt adhesive.
