What is Spunlace Nonwoven fabric?
Spunlace non-woven fabric is a kind of spunlace non-woven fabric by spraying high-pressure fine water flow onto one or more layers of fiber webs, so that the fibers are entangled with each other, so that the fiber web can be reinforced and have a certain strength. Its fiber raw materials come from a wide range of sources, which can be polyester, nylon, polypropylene, viscose fiber, chitin fiber, microfiber, tencel, silk, bamboo fiber, wood pulp fiber, seaweed fiber, etc.
Processing principle
The principle of spunlace reinforcing fiber web is similar to that of acupuncture, but instead of needling needles, the fiber web is sprayed by a spunlace machine using multiple fine water jets generated by high pressure. After the water jet passes through the fiber web, it is supported by the rebound of the net curtain and penetrates the fiber web again. As a result, the fibers in the fiber web are displaced, interspersed, entangled and cohesive under the hydraulic action of the high-speed water jets in different directions. Strengthen the web.
Main feature
1. Flexible entanglement, does not affect the original characteristics of the fiber, does not damage the fiber
2. Appearance is closer to traditional textiles than other non-woven materials
3. High strength and low fluff
4. High hygroscopicity, rapid moisture absorption
5. Good breathability
6. Soft feel and good drape
7. The appearance is varied
8. No need for adhesive reinforcement, washable
Applications
Spunlace non-woven fabrics are used for medical curtains, surgical gowns, surgical cover cloths, medical dressing materials, wound dressings, medical gauze, aviation rags, clothing lining fabrics, coating base fabrics, disposable materials, and advanced rags for instruments and meters. , High-grade rags, towels, cotton pads, wet wipes, mask covering materials, etc. in the electronics industry.Domestic
Domestic overview
1.Production line
My country's spunlace nonwoven production line is developing rapidly, among which Jiangsu and Zhejiang provinces are the most prominent. Especially after the economic crisis, the spunlace nonwoven industry has not only been unaffected, but has bucked the trend. barbed wire.
2.Production technology of spunlace cloth
The development direction of spunlace cloth technology is to move towards high-speed, high-quality, drum-type spunlace. The main reason that affects the progress of my country's spunlace technology is the lack of large-scale high-speed, high-output, high-quality carding machines; my country is still unable to manufacture drum-type spunlace. Spunlace machine; Lack of net laying machine with actual production speed of 70-100M/min or more.
3.Scientific research development
my country's spunlace nonwovens have been researched, developed and produced for nearly ten years. No matter in terms of variety, scale, quality, and equipment, they have been significantly improved, basically meeting the needs of national economic development. Spunlace nonwovens involve the fields of medicine and health, light industry, electronics, environmental protection and other disciplines, and promote the development of domestic traditional chemical fibers and differentiated fibers.
