Spunlace vs spunbond

 The production process and characteristics of spunbond non-woven fabric

Spunbonded non-woven fabric is a type of non-woven fabric that involves loosening, mixing, directing, and forming a mesh with fibers. After injecting adhesive into the mesh, the fibers are formed through pinhole forming, heating, curing, or chemical reactions to form a mesh structure. It has good softness and water absorption, with a soft touch, good breathability, and poor waterproofing. It is suitable for fields such as sanitary products, home textiles, and packaging.

The production process and characteristics of spunlace non-woven fabric

Spunlaced non-woven fabric is a non-woven fabric that forms a network structure by mixing fibers and spraying them under high-pressure water flow. It can form a network of fiber bundles without the need for adhesive, with good strength and wear resistance, as well as characteristics such as breathability, moisture absorption, and waterproofing. It is suitable for fields such as filter materials, carpets, and automotive interiors, especially those that require strength and durability.

There is no squeezing of the fiber mesh in the process of water jet grouting, which improves the swelling degree of the final product; Not using resin or adhesive, thus maintaining the inherent softness of the fiber mesh; The high integrity of the product avoids the occurrence of fluffiness; Fiber mesh has high mechanical strength, reaching 80% to 90% of textile strength; Fiber mesh can be mixed with any variety of fibers. It is worth mentioning that the water spunlace fiber mesh can be combined with any substrate to produce composite products. Products with various functions can be produced according to different uses.

Comparison of two types of non-woven fabrics

Process differences

Spunlaced non-woven fabric is made by using a high-pressure water column to pass through a fiber network and connect the fibers into a network, resulting in non-woven fabric. Spunbonded non-woven fabric is made by spinning, stretching, orientation, and molding synthetic fibers that have been sorted and dispersed under the conditions of organic solvent dissolution.

Differences in physical performance

1. Strength and water resistance: Spunlaced non-woven fabrics have high strength and good water resistance, while spunbond non-woven fabrics have relatively low strength and lower water resistance than spunbond non-woven fabrics.

2. Softness: Spunbonded non-woven fabric is softer than spunlaced non-woven fabric and may be more suitable for certain applications in certain fields.

3. Breathability: Spunlaced non-woven fabric has good breathability, while spunbond non-woven fabric has poor breathability.

Differences in applicable fields

1. In terms of medical and health purposes: Spunlaced non-woven fabric is mainly used in medical supplies, health care, disinfection products, and other fields. Spunbonded non-woven fabrics are mainly used in sanitary napkins, baby diapers, and other areas because of their high softness, making them more suitable for contact with the skin.

2. In terms of industrial use: Spunlaced non-woven fabric is mainly used for filtering materials, insulation materials, packaging materials, etc. Spunbond non-woven fabric is mainly used for manufacturing shoes, hats, gloves, packaging materials, etc.

Conclusion

In summary, there are differences in manufacturing methods, physical properties, and applicable fields between spunbond non-woven fabrics and spunbond non-woven fabrics. When selecting materials, one should choose non-woven fabrics that are suitable for their actual needs.
