What are the raw materials for spunlace nonwovens

Spunlace non-woven fabric is to spray high-pressure fine water onto one or more layers of fiber webs to entangle the fibers with each other, so that the fiber webs can be reinforced and have a certain strength. The obtained fabric is spunlace non-woven fabric. Its fiber raw materials come from a wide range of sources, such as polyester, nylon, polypropylene, viscose fiber, chitin fiber, microfiber, tencel, silk, bamboo fiber, wood pulp fiber, seaweed fiber, etc.

main ingreadient:

(1) Natural fibers: cotton, wool, linen, silk;

(2) Conventional fibers: viscose fiber, polyester fiber, acetate fiber, polypropylene fiber, polyamide fiber;

(3) Differential fibers: superfine fibers, shaped fibers, low melting point fibers, high crimp fibers, antistatic fibers;

(4) High-performance fibers: aramid fibers, carbon fibers, metal fibers.

The principle of processing:

The principle of hydroentanglement reinforcement is similar to the acupuncture process, but instead of needles, multiple fine water jets generated by high pressure are used to spray the fiber web. After the water jet passes through the fiber net, it is entrusted with the rebound of the net curtain and penetrates the fiber net again. Therefore, the fibers in the fiber net are displaced, interspersed, entangled and entangled under the hydraulic action of high-speed water jets interspersed in different directions, thereby Strengthen the web.

Features:

1. Flexible entanglement, does not affect the original characteristics of the fiber, does not damage the fiber

2. The appearance is closer to traditional textiles than other nonwoven materials

3. High strength, low fuzziness

4. High hygroscopicity, rapid moisture absorption

5. Good air permeability

6. Soft hand feeling and good drapability

7. The appearance is varied

8. No need for adhesive reinforcement, washable

9. Long production process and large floor area

10. Complex equipment and high water quality requirements

11. High energy consumption

Applications:

Spunlace non-woven fabrics are used for medical curtains, surgical gowns, surgical drapes, medical dressing materials, wound dressings, medical gauze, aviation wipes, clothing lining base fabrics, coated base fabrics, disposable materials, advanced instrumentation wipes , High-grade rags, towels, cotton pads, wet wipes, mask covering materials, etc. in the electronics industry.
