Imported spunbond dry-laid non-woven fabric refers to extruding and stretching the polymer to form continuous filaments, then laying the filaments into a web, and then the fiber web is bonded by itself, thermally bonded, chemically bonded or Mechanical reinforcement method turns the fiber web into a non-woven fabric.
The main materials of imported spunbond dry-laid non-woven fabrics are polyester and polypropylene.
The main products are polypropylene, polyester (long fiber, short fiber) non-woven fabrics.
The process flow of polypropylene spunbond non-woven fabric: polymer (polypropylene + recycled material) – large screw high temperature melt extrusion – filter – metering pump (quantitative delivery) – spinning (spinning entrance) Up and down stretching and suction) – cooling – air traction – mesh curtain forming – upper and lower pressure rollers (pre-reinforcement) – hot rolling in the rolling mill (reinforcement) – winding – reverse cloth slitting – weighing Packaging – finished product is put into storage.
The process flow of polyester spunbond non-woven fabrics: processed polyester chips – high-temperature melt extrusion of large snail stalks – filter – metering pump (quantitative delivery) – spinning (pull up and down at the spinning entrance) Stretching and suction) – Cooling – Air traction – Mesh curtain forming – Upper and lower pressure rollers (pre-reinforcement) – Hot rolling in the rolling mill (reinforcement) – Winding – Rewinding and slitting – Weighing and packaging – -Product storage.
Imported spunbond dry-laid non-woven fabrics have good high temperature resistance (polypropylene can be used in an environment of 150℃ for a long time, polyester can be used in an environment of 260℃ for a long time), aging resistance, UV resistance, high elongation and stability It has the characteristics of good air permeability, corrosion resistance, sound insulation, moth-proof, and non-toxicity. Our most common and commonly used applications are non-woven bags, non-woven packaging, etc.
It is easier to identify spunbond dry-laid non-woven fabrics: generally the two-way fastness is good, and the nipping points of spunbond non-woven fabrics are diamond-shaped.
