spunlace non-woven fabric is a production technology for non-woven fabrics, which mainly involves using high-pressure water flow to reinforce fiber webs, thereby forming a strong, soft, and versatile material. Specifically, the manufacturing process of spunlace non-woven fabric includes the following steps:
Fiber preparation: Firstly, prepare wood pulp, polyester, viscose, or other synthetic or natural fiber materials into fibrous form, which can be short fibers or long fibers.
Web formation: These fibers are arranged into a loose fiber web through methods such as air flow, combing, or spinning. The fiber network structure formed at this stage is relatively loose and has not undergone reinforcement treatment.
spunlace reinforcement: The key step is to send the fiber mesh into the water jet device. During this process, multiple sets of high-speed jets of small water columns (typically at speeds of several hundred meters per second) impact the surface and back of the fiber web. The impact force of water causes fibers to entangle and entangle with each other, forming a physically bonded structure without the need for chemical adhesives. This process greatly improves the strength and stability of non-woven fabrics.
Drying and finishing: The fiber mesh treated with spunlace contains a large amount of moisture, which needs to be removed by hot air drying or other methods to solidify and form. Subsequently, post-processing steps such as calendering, cutting, and winding may be carried out to meet the needs of different applications.
spunlace non-woven fabric is widely used in various fields such as medical and health care (such as surgical gowns, masks, bandages), daily consumer goods (wet wipes, makeup remover cotton), household items (such as cloths, tablecloths), and filter materials due to its softness, good moisture absorption, strong breathability, environmental friendliness, and non toxicity.
