 Huzhou Sanjin interlining explains the characteristics of two groups of spunbonded non-woven fabrics Updated by:2021-12-21 Categories: Industry news
I believe many friends don't know much about PE / PP dual group spunbonded fabric. PE / PP dual group spunbonded fabric is made of PE polyethylene and PP polypropylene by spunbonded method, with double-layer skin core structure. Different from traditional PP spunbonded cloth and hot air cloth, PE / PP two-group spunbonded cloth has the characteristics of soft hand feel, smooth touch, good thermal bonding, high tensile strength, safety, no addition, no stimulation and so on! So Huzhou Sanjin non-woven interlining Xiaobian today will specifically analyze the characteristics of two groups of spunbonded non-woven fabrics. 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, non-woven fabrics need to have better safety.
As we all know, various additives must be added to PP spunbonded non-woven fabric in order to achieve better softness. However, PE / PP dual group spunbonded fabric can achieve better heat sealing and softness without any addition and modification.
PE / PP bicomponent fiber is 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 ℃). During hot rolling melting, the lower temperature is used, the melting and bonding of the skin layer, and the performance of the core layer remains unchanged. When bonding with the adhesive, the effect is not to destroy the viscosity of the adhesive, and it can prevent composite delamination and rubber tendon creep. There is no need to add softeners, smoothing agents, elastomers and other auxiliary agents.
The characteristics of no additives in the production process of PE / PP two-component spunbonded 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.
