The difference between spunlace nonwovens and spunbond nonwovens

The concept of spunlace nonwovens: spunlace nonwovens, also called spunlace nonwovens, also known as 'spunlace cloth'. The concept of 'spunlace fabric' comes from the mechanical acupuncture process. The so-called 'sprayed net' is to use high-pressure water flow to penetrate into the fiber web, so that the fibers are entangled with each other, so that the loose fiber web from the original spunlace non-woven fabric has a certain strength and a complete structure.

The process flow is: fiber metering and mixing-opening and impurity removal-mechanical messy carding into web-fiber web pre-wetting-water needle entanglement-surface treatment-drying-coiling-inspection-packaging library. The jet net device is to use the high-pressure water flow of high-speed spunlace non-woven fabric manufacturers to spray the fiber web, so that the fibers in the fiber web are rearranged and entangled with each other, turning into ultra-fine fiber non-woven fabrics with complete structure, certain strength and other Performance non-woven. The physical properties of this spunlace non-woven bag are different from common needle-punched non-woven fabrics, and it is the only non-woven fabric that can make the final product similar to textiles in terms of hand feel and microfiber non-woven fabric properties. Advantages of spunlace:

There is no extrusion of the fiber web in the spunlace process, thereby increasing the bulkiness of the final product; no resin or binder is used, thereby preserving the spunlace The non-woven fabric maintains the inherent softness of the fiber web; the high integrity of the product avoids the fluffy phenomenon of the product; the fiber web has high mechanical strength, up to 80% to 90% of the strength of the textile; the fiber web can be used in any variety. fiber mix. It is particularly worth mentioning that the spunlace web can be compounded with any base fabric to make a compound product. Products with various functions can be produced according to different uses.

Advantages of spunlace cloth: 1. Soft, good drapability; 2. Good strength; 3. High hygroscopicity and quick-wetting; 4. Low fluff; 5. Washable; 6. No Chemical additives; 7. Appearance similar to textiles. The prospect of spunlace: Due to the advantages of spunlace, it has become a field with the fastest technological progress in the non-manufacturing world in recent years. The development direction of non-woven fabrics is to replace textiles and knitted fabrics. Spunlace fabrics have become the most potential field to compete with the textile market due to its most similar characteristics to textiles, excellent physical properties, and the advantages of high quality and low price.

Application of spunlace cloth:

1. Disposable surgical gowns, surgical covers, surgical table cloths, surgical aprons, etc. for medical purposes; wound dressings, bandages, gauze, Band-aids, etc.;

2. Clothing such as clothing interlinings, baby clothes, training clothes, disposable color clothes for carnival nights, various protective clothes such as surgical gowns, etc.;

3. Wipe Towels such as household, personal, beauty, industrial, medical wet wipes, etc; , Agricultural products such as thermal insulation greenhouses, anti-weed growth, harvest cloth, insect-proof and fresh-keeping cloth, etc.;

Six, spunlace non-woven fabrics can also be used for composite processing to produce 'sandwich' structure. products, and develop new composite materials for a variety of uses. Spunbond non-woven 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, chemically bonded or mechanically reinforced. , so that the web becomes a non-woven fabric.

Features: high strength, good high temperature resistance (can be used for a long time in 150 ℃ environment), aging resistance, UV resistance, high elongation, good stability and air permeability, corrosion resistance, sound insulation, anti-aging Moth, non-toxic. Main uses: The main products of spunbond non-woven fabrics are polypropylene polyester (long fiber, staple fiber). The most common and most commonly used are non-woven bags, non-woven packaging, etc., and they are also easy to identify. Because the nip point of the spunbond nonwoven is diamond-shaped.
