The difference between non-woven fabrics and traditional textiles:
Non-woven industry |
Traditional textile industry |
Capital-intensive and technology-intensive |
Labor-intensive |
Wide range of raw materials |
Limited source of raw materials |
Wide range of product applications |
Small product application range |
Fast product forming |
Slow product molding |
Low production cost |
Higher production costs |
Poor strength and tensile strength, used for secondary products |
Strong, tensile strength, can be used repeatedly |
Thermal-bonded non-woven: Staple fiber is used like airthrough non-woven fabric, and the strength is maintained by the nip point
Airthrough non-woven
Spunbonded non-woven
Airthrough non-woven:
The fluffy, soft feel, good water delivery and air permeability of airthrough non-woven fabrics have been widely recognized by consumers. More and more diaper manufacturers have changed their original products using hot-rolled or spunbonded non-woven fabrics to Airthrough non-woven fabric is the surface material.
The basic requirements of non-woven fabrics:
The uniformity of non-woven fabrics is the basis for meeting your product performance requirements.
★ The uneven non-woven fabric will increase the liquid penetration speed, reduce the function of diversion and temporary storage, and increase the amount of reverse osmosis. Macromolecules are easy to leak out, and the quality of the perforated nonwoven fabric cannot be guaranteed when the nonwoven fabric is punched.
★ Front and back of non-woven fabric
Smooth surface---refers to the surface of the non-woven fabric attached to the mesh.
Rough surface---refers to the non-mesh surface when the non-woven fabric is manufactured.
★Single-layer non-woven fabric, when the smooth surface is obvious, the use function is slightly poor, when the non-woven fabric is not obvious, the use function is better.
