Spunbonded non-woven fabric is a kind of non-woven fabric, usually refers to polyester spunbonded, polypropylene spunbonded, most of the non-woven fabrics on the market are produced by spunbonded method, we commonly usedThe spunbonded non-woven fabric is the non-woven bag, non-woven packaging, etc., the characteristics of spunbonded non-woven wear resistance, firm feel good, etc., make it a good choice for making such products.

next  Understand the spunbond non-woven process flow.

What is spunbonded non-woven fabric

Spunbonded non-woven fabric is the polymer extrusion, stretching, forming a continuous filament, the filament laid into a net, and then through self-bonding, thermal bonding, chemical bonding or mechanical addition

Solid method, so that the fiber network into non-woven fabric.

Second, the characteristics of  spunbonded non-woven fabrics

Good high temperature resistance, good low temperature resistance (two nylon can be used in 150°C environment for a long time, polyester can be used in 260°C environment for a long time), aging resistance, UV resistance

High elongation, good stability and air permeability, corrosion resistance, sound insulation, mothproof, non-toxic.

The main materials of spunbonded non-woven fabrics are polyester (long fiber, short fiber) and polypropylene, and the spunbonded non-woven fabrics we commonly use are mainly non-woven bags and non-woven bags

Installation, etc., the application level can also be made of flower packaging cloth, luggage cloth, etc., others are also widely used in agricultural harvest cloth; Medical, industrial - secondary products; Furniture lining; Hotel hygiene products, etc.

Fourth, the process flow of spunbond non-woven fabric

Nylon; Polymer (polypropylene + refeed)- large screw high temperature melt extrusion - filter

Gauge pump (volume transfer)- spinning (spinning inlet is pulled up and down

Stretch suction)- Cooling - air traction - mesh screen forming - upper and lower press roller (pre-fixation)-

Mill hot rolling (reinforcement)- winding - reverse slitting - weighing

Packaging - Finished product into storage.

Polyester; The treated polyester slice - large screw rod melt extrusion at high temperature

Filter - gauge pump (quantitative delivery)- spinning (drawing up and down the spinning inlet suction

)- Cooling - Air traction - mesh screen forming - upper and lower press roller (pre-reinforcement)- rolling mill hot rolling (reinforcement)- winding - reverse cloth slitter - weighing and packaging - finished product storage.
