Characteristics and application of spunlaced nonwovens raw materials | JINHAOCHENG

Spunlace nonwovens fabric have a wide variety of raw materials, but not every kind of fiber raw materials can be improved by spunlacing combined with production process, product use, production cost and other factors. Among the commonly used chemical fibers, more than 97% of spunlaced products use polyester fiber to improve the strength and structural stability of products; viscose fiber is a large number of fiber raw materials. It has the characteristics of good water absorption, non-pilling, easy cleaning, natural degradation and so on. Widely used in spunlaced products; polypropylene fiber is widely used in sanitary materials in contact with human skin because of its low cost, non-irritation to human skin, non-allergy and fluffy; because of the cost of water-absorbing cotton and the quality requirements of raw materials, water-absorbing cotton is not widely used in the field of spunlacing, but the blended products of water-absorbing cotton and other fibers have been used in the fields of medical treatment and wiping cloth.

Spunlace reinforcement technology has good adaptability to raw materials. It can strengthen not only thermoplastic fibers, but also non-thermoplastic cellulose fibers. It has the advantages of short production process, high speed, high output, no wu dyeing to the environment and so on. Spunlaced reinforcement products have good mechanical properties and do not need to be reinforced by adhesives. Spunlaced nonwovens are not easy to fluff and fall off. The appearance performance is close to that of traditional textiles, with a certain degree of softness and feel; there are a variety of products, which can be plain or jacquard: different hole types (round, oval, square, long). Lines (straight lines, triangles, herringbone, patterns) and so on.

Compared with acupuncture, spunlaced workers are more adaptable to products with different surface densities; in addition, thin spunlaced nonwovens are relatively easy to decompose and can be used and discarded, or recycled for waste spinning. This is a kind of environmentally friendly textile. With many advantages, spunlaced products quickly occupy the market of industrial cloth such as sanitary materials (medical treatment, wiping, etc.), synthetic base cloth (battery diaphragm, clothing lining, building materials, etc.). With the development of spunlaced nonwovens technology, the performance of spunlaced nonwovens is continuously improved, the variety of products is more and more abundant, and the uses are expanding. With its unique performance, its market share is getting higher and higher.

Wipe sanitary products

There are a variety of products on the nonwovens market, which are widely used in disposable products such as home, medical and personal care, as well as other products. However, rags with huge sales potential account for nearly half of the market share. Wipe products mainly include personal care wiping cloth, industrial wiping cloth and household wiping cloth. In addition, the demand for spunlaced nonwovens in the health field is expanding, such as baby wipes, wipes, household cleaning products and so on. Now spunlaced products have been widely used. In the past, spunlaced nonwovens were also used in almost all products, such as overheated diapers and women's sanitary napkins, as well as spunlaced nonwovens.

Medical and health materials

Medical sanitary materials are also an important application field of spunlaced nonwovens. Products include surgical curtains, surgical clothes and surgical caps, gauze, cotton and other products. The properties of viscose fiber are similar to those of cotton fiber. The performance of nonwovens produced with the proportion of 70x30 is very close to that of traditional cotton gauze, which makes it possible for spunlaced products to replace cotton gauze, and spunlaced products made of antibacterial chitin fiber not only have good bactericidal ability. and can effectively promote wound healing.

Synthetic leather base cloth

Spunlaced nonwovens are soft, feel good, breathable and moisture permeable, with shallow spunlace and small spunlaced holes. After the base cloth is coated, the performance of the product is close to that of natural leather and has good simulation. The spunlaced nonwovens with cross laying process has the strength and trend to replace the traditional textile substrate because of the small difference between longitudinal and transverse strength.

Filter media

Spunlaced nonwovens have small pore size and uniform distribution, so they can be used as filter materials. For example, the spunlaced felt made of high temperature resistant materials and woven fabrics has the advantages of high filtration accuracy, good dimensional stability and long service life, which can not be compared with other nonwovens.
