Classification of non-woven fabrics according to the production process

According to the production process, non-wovens can be divided into spunlaced non-wovens, thermal bonded non-wovens, pulp air mesh non-wovens and so on. The details are as follows:

spunlace non woven fabric

spunlace non woven fabric Spunlace non woven fabric is sprayed into the fiber mesh by high-pressure micro-water flow, so that the fibers are intertwined and strengthened. This process does not affect the original characteristics of the fiber, does not damage the fiber, the produced non-woven fabric has high strength, low fuzziness, strong moisture absorption and other characteristics.

Application: Due to its good softness and hygroscopicity, spunlaced nonwovens are widely used in medical fields, such as surgical gowns, medical dressing materials, wound dressings, etc. It is also used for clothing lining base cloth, coating base cloth and cosmetic cotton.

Heat bonded non woven fabric

Process features: Fiber or powder hot melt bonding material is added to the fiber mesh, which is reinforced into a cloth after heating and melting and cooling. Surface bonding hot rolling surface is more smooth, point bonding hot rolling is relatively fluffy.

Application: Hot bonded non-woven fabrics are mainly used in baby diapers, women's sanitary napkins covering materials, ointment base cloth, clothing lining and masks. Especially in the field of sanitary products, it provides good water resistance and air permeability.

Pulp air into mesh non woven fabric

Process features: The wood pulp fiberboard is loosened into a single fiber state by air mesh technology, and then the fiber is agglutinated on the mesh curtain by air flow method and reinforced. This kind of non-woven fabric has good plumbness, soft feel and strong moisture absorption.

Application: Mainly used in high water absorption disposable sanitary products, such as diapers, sanitary napkins, wet face towels and wipes.

Wet non woven fabric

Process characteristics: The fiber raw materials placed in the water medium are loosened into a single fiber, and different fiber raw materials are mixed at the same time to make suspended pulp, and then in the wet state into a network reinforcement. The process has high production speed and can make full use of short fibers.

Application: Wet non-woven fabrics are often used in special paper (such as filter paper, tea bags), industrial filters, insulation materials, sound absorption materials and medical backing, tape and wrapping materials.

Spunbond non woven fabric

Process characteristics: The polymer is extruded and stretched to form a continuous filament, and then laid into a net, and then through self-bonding, thermal bonding, chemical bonding or mechanical reinforcement methods into non-woven fabric.

Application: Polypropylene (PP) spunbonded non-woven fabric can be used for geotextile, carpet substrate, coating substrate, etc. Polyester (PET) spunbonded non-woven fabrics are used for filtration materials, lining materials, tufted carpet substrates, etc.

Melt blown non woven fabric

Process characteristics: The polymer is fed and melted and extruded to form fine fibers, which are netted and reinforced after cooling. The fiber network is composed of very fine short fibers, which has good filtration and liquid absorption performance.

Application: Mainly used in filtration materials, medical and health materials, clothing materials, battery separator materials and wiping materials.

Needled non woven fabric

Process features: The fluffy fiber net is reinforced into cloth by stinging needle. Flexible entanglement between fibers, with good dimensional stability and elasticity.

Application: Needled non-woven fabric is widely used in gardening cloth, shopping bags, a variety of collection patterns or three-dimensional molding products, with good permeability and filtration performance.

Stitch bonded non woven fabric

Process features: Reinforcement of fiber mesh, yarn layer or non-textile material through warp knitting coil structure. This is a dry non-woven fabric, suitable for reinforcement of a variety of materials.

Application: stitch-woven non-woven fabrics are used for non-woven products that need to be reinforced, such as some packaging materials, industrial filters, etc.

Hydrophilic non woven fabric

Process characteristics: mainly used in the production of medical and health materials, in order to obtain better feel and no skin damage. Hydrophilic nonwovens are specially treated to improve their ability to absorb and diffuse water.

Application: Mainly used in sanitary napkins, sanitary gaskets and other products that need hydrophilic function.

To sum up, according to the production process, non-woven fabrics can be divided into spunlace, hot bonding, slurry air mesh, wet method, spunbond, meltblow, needling, sewing and hydrophilic and other types, each process has its own unique characteristics and scope of application. Choosing the right type of non-woven fabric can maximize the needs of specific application areas.
