A spunlace nonwoven is a fabric made from fibers processed by the spunlace method. Fibers can be natural fibers, such as cap, silk, hemp, cotton, etc.; or conventional fibers, polypropylene fibers, acetate fibers, polyamide fibers, etc.; differentiated fibers, shaped fibers, microfibers, high crimp fibers, low melting point fibers etc.; and high-performance fiber carbon fiber, metal fiber, etc.
Spunlace uses high-pressure fine water jets onto a fiber web. Under the action of the interpenetrating water flow, these fibers will displace and begin to entangle and hold together, which means that the fibers will be twisted into one, thereby strengthening the fiber web. Therefore, spunlace non-woven fabrics are stronger than ordinary non-woven fabrics, will not destroy the flexibility of fibers, and have good air permeability.
The main raw material of spunlace non-woven fabrics.
(1) Natural fibers: cotton, wool, hemp, silk;
(2) Conventional fibers: viscose fiber, polyester fiber, acetate fiber, polypropylene fiber, nylon;
(3) Differentiated fibers: ultrafine fibers, special-shaped fibers, low melting point fibers, high crimp fibers, antistatic fibers;
(4) High functional fibers: aramid fibers, carbon fibers, metal fibers.
Application of spunlace nonwovens.
(1) Medical hygiene non-woven fabrics: surgical gowns, protective clothing, disinfection wraps, masks, diapers, civilian wipes, rags, wet face wipes, magic towels, soft towel rolls, beauty supplies, sanitary napkins, sanitary pads, disposable Sexual hygiene products, clothing, etc.;
(2) Non-woven fabrics for home decoration: wall coverings, tablecloths, bed sheets, bedspreads, etc.;
(3) Non-woven fabrics for clothing: lining, adhesive lining, cotton filling, shaping cotton, various synthetic leather base fabrics, etc.;
(4) Non-woven fabrics for industrial use; filter materials, thermal insulation materials, cement packaging bags, geotextiles, coverings, etc.;
(5) Agricultural non-woven fabrics: crop protection fabrics, rice planting fabrics, irrigation fabrics, thermal insulation curtains, etc.;
(6) Other non-woven fabrics: space cotton, thermal insulation materials, linoleum, cigarette filters, tea bags, etc.
Normal gram weight: 30gsm to 80gms
Characteristics of spunlace non-woven fabrics.
1. The spunlace non-woven fabric uses the spunlace method to make the fibers flexible and tangled together, which will not cause damage to the fibers and does not affect the unique softness of the fibers. So it is both firm and soft.
2. The appearance of spunlace non-woven fabrics is very close to traditional textiles. Unlike other fabrics made of non-woven materials, it looks more natural and soft.
3. Due to the high strength of the spunlace non-woven fabric, it is wear-resistant and tensile during use, and is not easy to accumulate. It's made without any binders and its strength is entirely fiber-based, so it doesn't weaken with every wash.
4. This fabric has strong hygroscopic ability and can quickly absorb moisture into the fiber web. The spunlace non-woven fabric is also very breathable, making it possible to make clothes without feeling stuffy.
5. The appearance design of spunlace non-woven fabric is very rich, and it can change a variety of patterns to meet various aesthetic needs.
production technology.
The research and development of spunlace composite technology not only overcomes the limitations of some non-woven products, increases the variety of colors, greatly broadens the application field of spunlace non-woven fabrics, but also promotes the development of spunlace technology and even the entire non-woven fabric technology. develop and improve.
Spunlace and wood pulp airlaid composite technology. Because the price of wood pulp is much cheaper than that of short fibers commonly used in spunlace, and the fluffy pulp has good hygroscopicity and hand feel, the products made are cheaper than those made of full fibers and are very competitive in price. But this process requires a very high filtration system. The product can be used as a wipe (70% g/m2), diaper and sanitary napkin core.
