PET Spunbond Nonwoven Fabric Specialty

Yiwu Guanghong Non-Woven Co.,Ltd | Updated: Oct 09, 2017

Geotextile is a non-woven fabric of a large product type, but also Tian Dingfeng focus and layout of a major area. As the geotextile application environment is more complex, usually with strong acid, strong alkaline environment, and polypropylene spunbond non-woven fabrics with acid and alkali characteristics, PET Spunbond Nonwoven Fabric so in the field of geotextile applications are more extensive.

In the production process to be continuous and stable polypropylene filament, the use of polypropylene raw materials have a certain performance requirements. General requirements are greater than 95%. Melt flow rate greater than 35g / min, ash ≤ 150ppm.

Polypropylene spunbond non-woven fabrics with high tensile strength, PET Spunbond Nonwoven Fabric low density, good water stability, good acid and alkali resistance, good fatigue resistance (second only to nylon), high elongation, stability and good air permeability , Corrosion-resistant, soundproof, moth, non-toxic characteristics.

Compared with polyester spunbond nonwoven fabric, polypropylene nonwoven fabric has the characteristics of low density, good water resistance, good acid and alkali resistance and good resistance to fatigue

PE / PP bicomponent fiber is a core-sheath composite structure, the core material for the polypropylene (PP) (melting point of about 165 ℃), cortex material for the polyethylene (PE) (melting point of about 130 ℃). Hot melt melting, the use of lower temperature, cortical melt bonding, PET Spunbond Nonwoven Fabric core properties remain unchanged. Adhesive with the glue when the effect does not damage the sticky adhesive, can prevent composite layer, anti-corrosion creep. No need to add softeners, slip agents, elastomers and other additives.

PE / PP two-component spunbond production process without adding additives in the characteristics of the diaper just meet the security needs. In the diaper storage process, there is no any additives precipitation, PET Spunbond Nonwoven Fabric will not affect the adhesion of hot melt adhesive.

Spunbond and meltblown process is relatively short, the process to be completed in the instant, thus increasing the difficulty of the process technology. In this whole production line, contains a lot of key core technology. For example, the design of the die, manufacturing and assembly debugging, PET Spunbond Nonwoven Fabric there are many difficulties. However, through the years of practice, China Textile Technology has mastered the core technology of key parts, parts and parts from the melt pipe to the hanger form, distribution, spinning and laying process. Of course, some key components also need to be produced by the collaboration units. But regardless of their own production or collaboration units supporting, have strict quality control measures, must meet the design requirements, product standards, PET Spunbond Nonwoven Fabric so as to ensure the overall level of the project.
