Spunlace non-woven fabric concept: Spunlace non-woven fabric, also known as spunlace non-woven fabrics, also known as "spray mesh into cloth." The concept of "spunlacing into cloth" is a type of spunlace nonwoven fabric that comes from a mechanical acupuncture process. The so-called "spray spray net" is the use of high-pressure water jet piercing the fiber network, so that the fibers intertwined with each other, so that the raw spunlace nonwoven fabric to loose the network has a certain strength and integrity of the structure.

The process flow is: fiber metering mixed-opening and removing impurities-mechanical disordered carding-fiber web pre-wetting-water needle interlacing-surface treatment-drying-winding-inspection-packaging storage. Jet spouting device uses high-pressure water jets of high spunlace non-woven fabrics to jet the web, so that the fibers in the web are re-arranged and intertwined to become ultra-fine fibers. The non-woven structure is complete, with certain strength and other Performance of non-woven fabrics. The physical properties of this spunlaced non-woven bag are different from those of the common needle-punched non-woven fabrics, and they are the only non-woven fabrics that can make the final product resemble a textile in terms of the hand and the performance of the ultrafine fiber non-woven fabric.

Spunlace superiority:

In the spunlace process, there is no squeezing of the fiber web, which increases the bulkiness of the final product; no resin or adhesive is used, so that the spunlace non-woven fabric holds the inherent softness of the web; The high degree of integrity avoids fluffiness of the product; the web has high mechanical strength and can reach 80% to 90% of the textile strength; the web can be mixed with any type of fiber. It is particularly worth mentioning that the spunlaced web can be compounded with any base fabric to make a composite product. Various functional products can be produced according to different uses.

Spunlaced fabric advantages: 1, soft, good drape; 2, good strength; 3, with high hygroscopicity and fast-moisture; 4, low fuzzing; 5, washable; 6, no chemical additives; Similar to textiles. The prospect of spunlace cloth: Due to the advantages of spunlace cloth, it has become one of the fastest technological advancements in the non-manufacturing industry in recent years. The development direction of non-woven fabrics is to replace textiles and knitwear products. Spunlaced fabrics have become the most potential areas of competition with the textile market because of their most textile-like features, excellent physical properties, and low prices.

The use of spunlace nonwovens is medical curtains, surgical gowns, surgical cover cloths, medical dressings, wound dressings, medical gauze, aero wipes, garment lining base fabrics, coated base fabrics, disposable materials, instrumentation senior wipes , electronic industry senior rags, towels, cotton, wipes, masks and other materials.

The spunlaced non-woven fabrics can also be used for composite processing, and new composite materials with multiple applications can be developed. Spun-bonded non-woven fabrics: After the polymer is extruded and stretched to form continuous filaments, the filaments are laid into a web, and the web is then bonded, thermally bonded, chemically bonded, or mechanically consolidated. Make the web a non-woven fabric.

Features: High strength, good high temperature resistance ( long-term use in 150°C environment), anti-aging, anti-ultraviolet radiation, high elongation, good stability and breathability, corrosion resistance, sound insulation, anti-mite, non-toxic. Main application: The main products of spunbonded non-woven fabrics are polypropylene polyester fiber (long fiber, short fiber). The most common and commonly used products are non-woven bags, non-woven packaging, etc., and they are also easy to identify. Because the nip of spunbonded nonwovens is diamond-shaped.
