Needle punched non-woven fabric and water spunlaced non-woven fabric are both types of non-woven fabric, which are used for dry/mechanical reinforcement in non-woven fabrics.
Needle punched non-woven fabric
Needle punched non-woven fabric is a type of dry process non-woven fabric, which involves loosening, combing, and laying short fibers into a fiber mesh. Then, the fiber mesh is reinforced into a fabric through a needle. The needle has a hook, which repeatedly punctures the fiber mesh and reinforces it with the hook, forming a needle punched non-woven fabric. Non woven fabric has no distinction between warp and weft lines, and the fibers in the fabric are messy, with little difference in warp and weft performance. The proportion of needle punched non-woven fabrics in non-woven fabric production lines is 28% to 30%. In addition to being used for conventional air filtration and dust control, the new application space of needle punched non-woven fabrics is being expanded, including transportation, industrial wiping, and so on.
The difference between spunlace non-woven fabric and needle punched non-woven fabric
Different manufacturing processes
Spunlaced non-woven fabric uses high-pressure water beams to strike, mix, and rub the fiber mesh, gradually combining the fibers to form a non-woven fabric, so it has good strength and softness. Needle punched non-woven fabric is made by spinning fibers into a mesh through electrostatic and chemical processes, and then combining the fiber mesh into a fabric using needle punching machines, crochet, and blending methods.
Different appearance
Due to different manufacturing processes, the surface of spunlaced non-woven fabric is relatively flat, with a soft texture, comfortable hand feel, and good breathability, but it does not have the plush and thick feeling of spunlaced non-woven fabric. The surface of needle punched nonwoven fabric is relatively rough, with a lot of plush and a hard feel, but it has good load-bearing capacity and rigidity.
Weight difference
The weight of needle punched non-woven fabric is generally higher than that of water punched non-woven fabric. The raw materials for spunlace non-woven fabric are relatively expensive, the fabric surface is delicate, and the production process is cleaner than needle punching. Acupuncture is generally thicker, with a weight of over 80 grams. The fibers are thicker, the texture is rougher, and there are small pinholes on the surface. The common weight of prickly cloth is below 80 grams, while the special weight ranges from 120 to 250 grams, but it is rare. The texture of the prickly cloth is delicate, with small longitudinal stripes on the surface.
Different characteristics
Spunlaced non-woven fabric is more flexible and comfortable than needle punched non-woven fabric, with better breathability, but its strength and stiffness are slightly inferior to needle punched non-woven fabric. Spunlaced non-woven fabric is suitable for use in medical, health, hygiene, sanitary ware, and other fields due to its flat fiber structure and certain gaps between fibers, making it more breathable. Although needle punched nonwoven fabric has high hardness, it is suitable for use in fields such as building insulation, geotechnical engineering, and water conservancy protection due to its better load-bearing capacity and rigidity. At the same time, due to its plush nature, it can also be used as a thermal insulation material in clothing.
Different uses
Due to the differences in characteristics between spunlace non-woven fabrics and needle punched non-woven fabrics, their uses are also different. Spunlaced non-woven fabrics with flexibility and permeability are suitable for medical treatment, health care, hygiene, sanitary ware, napkin, toilet paper, facial mask and other purposes; And needle punched non-woven fabrics are commonly used as waterproof materials, filtering materials, geotextiles, automotive interior and sound insulation materials, sound insulation materials, insulation materials, clothing lining, shoe lining and other fields.
Conclusion
In summary, although both spunlace non-woven fabric and needle punched non-woven fabric are a type of non-woven fabric, their manufacturing process, appearance, characteristics, and uses have significant differences. When selecting non-woven materials, different materials should be selected according to the desired use.
