(Summary description)Spunlace nonwovens concept: Spunlace nonwovens, also known as spunlace nonwovens, are also called "jet spunlace." The concept of "jet-jetting into cloth" comes from the mechanical needling process. The so-called "jet-jet mesh" is to use high-pressure water to penetrate into the fiber web, entangle the fibers with each other, so that the original spunlace nonwoven fabric has a certain strength and complete structure.

Spunlace nonwovens concept: Spunlace nonwovens, also known as spunlace nonwovens, are also called "jet spunlace." The concept of "jet-jetting into cloth" comes from the mechanical needling process. The so-called "jet-jet mesh" is to use high-pressure water to penetrate into the fiber web, entangle the fibers with each other, so that the original spunlace nonwoven fabric has a certain strength and complete structure.

The process is as follows: fiber metering and mixing-opening and impurity removal-mechanical random carding into the web-fiber web pre-wetting-water needle entanglement-surface treatment-drying-winding-inspection-packing and storage. The jet spraying device is a high-pressure spun nonwoven fabric manufacturer that uses high-speed water jets to spray the web, so that the fibers in the web can be rearranged and entangled with each other to become a non-woven fabric with complete structure and certain strength and other properties. The physical properties of this spunlace non-woven bag are different from the common needle-punched non-woven fabrics. They are the only non-woven fabrics that can make their final products similar to textiles in terms of feel and ultra-fine fiber non-woven fabric performance. Advantages of spunlace:

  There is no extrusion of the fiber web in the spunlace process formula, thereby increasing the bulk of the final product; no resin or adhesive is used, thereby maintaining the inherent softness of the fiber web; the high integrity of the product is avoided The product has a fluffy phenomenon; the web has a high mechanical strength, which can reach 80% to 90% of the strength of the textile; the web can be mixed with any type of fiber. It is particularly worth mentioning that the spunlace web can be compounded with any base fabric to make a composite product. Products with various functions can be produced according to different purposes.

  Advantages of spunlace cloth: 1. soft, good drape; 2. good strength; 3. high hygroscopicity and quick-wetness; 4. low fluff; 5. washable; 6. no chemical additives; 7. appearance Similar to textiles. Prospects of spunlace: Due to the advantages of spunlace, it has become the fastest-growing field in non-manufacturing technology in recent years. The development direction of non-woven fabrics is to replace textiles and knitwear. Spunlaced fabrics have the most potential for competition with the textile market due to their most textile-like characteristics, excellent physical properties, and low cost.

Application of spunlace:

I. Disposable surgical gown, surgical cover cloth, operating table cloth, surgical apron, etc. for medical use; wound dressings, bandages, gauze, band-aids, etc.

Second, clothing such as clothing lining, baby clothes, training clothes, carnival night disposable color clothing, various protective clothing such as surgical clothes, etc .;

Third, wipes such as household, personal, beauty, industrial, medical wipes, etc .;

Fourth, decorative cloths such as car interiors, home interiors, stage decoration, etc.

V. Agricultural products such as thermal insulation greenhouses, anti-weed growth, bumper cloth, insect-resistant fresh cloth, etc .;

6. Spunlace nonwovens can also be used for composite processing, which can produce products with a "sandwich" structure, and develop new composite materials for multiple uses. Spunbond nonwoven fabric: 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, and chemically bonded. Or mechanical reinforcement method to make the web into a non-woven fabric.

  Features: high strength, good high temperature resistance (can be used in a 150 ℃ environment for a long time), aging resistance, UV resistance, high elongation, good stability and breathability, corrosion resistance, sound insulation, anti-scratching, non-toxic. Main uses: The main products of spunbond non-woven fabrics are polypropylene polyester (long fiber, short fiber). The most common and most commonly used applications are non-woven bags, non-woven packaging, etc., and it is easy to identify. Because the embossing point of spunbond non-woven fabric is diamond.
