Nonwoven Fabrics Are Increasingly Used In Various Fields Of The Clothing Industry.

Nonwoven fabrics, also known as nonwovens.

It refers to a fiber layer composed of a certain orientation or random arrangement without the traditional spinning, weaving or knitting process, or woven fabric interwoven by the fiber layer and yarn, and woven through mechanical hooking, suture or chemical and hot melting methods.

Compared with other clothing materials, non-woven fabrics have the advantages of short production process, high yield, low cost, wide application of fiber, excellent product performance and wide range of uses.

In the field of nonwoven applications, the rise of nonwoven fabrics, though half a century ago, has developed rapidly.

Because of its unique structure and processing mode, it has broad application prospects.

The structure of non-woven fabrics can be divided into the following categories according to the composition and formation methods of the web.

1 woven fabric without fabric

(1) fiber bonding is to fold short fibers into thin flaky fibrous webs, making cloth by bonding the fibers themselves or vertically and horizontally.

It includes adhesive bonding and hot melt bonding.

A. adhesive bonding refers to the use of synthetic resin or synthetic fiber adhesive.

The fiber net is solidified and bonded into a non woven fabric that can not be separated.

According to the binder type and processing method, it can be divided into point bonding, film bonding, agglomeration bonding and local adhesion.

This type of nonwoven fabric has good breathability, but it has a hard handle and is used for wall covering and disposable products.

B. hot-melt bonding refers to the addition of hot melt fibers into the fibrous net in advance. When the overlapped fibrous net is heated by a calender, the melting of hot melt fibers in the area of the rolling point or stripe is reinforced, so as to bond with other fibers.

This nonwoven fabric has good filtration performance, elasticity and fluffiness, good air permeability and hygroscopicity. It is suitable for making winter clothing's filler, bedding material, filter cloth, automobile cloth and tufting carpet base cloth.

(2) the agglutinate nonwoven fabric of intertwined fibers refers to the nonwoven fabric similar to felt structure, which is made by overlapping the appropriate fiber net and making the fibers interlocked well in a certain way, such as needling and sewing.

According to the way of action, it can be divided into needling method, jet net spraying method, spunbonded method and braiding method.

A.

Nonwoven fabrics use thousands of special crochet hooks to move up and down repeatedly through the fiber net, making the entire fiber net become a dense, felt nonwoven fabric that is entangled, entangled and separated from each other.

This kind of product has a wide range of uses, and can be widely used in geotextiles, bed blankets, filtering materials, needle felt and artificial leather bottom cloth.

B. jet net method is also called non needle punched nonwovens.

It uses many bundles of strong water to shoot into the mesh to reinforce cloth.

It has high strength, full handle and good permeability, suitable for clothing lining, shoulder pads and so on.

C. spunbonded nonwovens synthetic fibers are extruded from the spinning head to make filament. At the same time, the static and high-pressure airflow is generated to make the fibers randomly and randomly fall on the metal curtain, and then the heat roller is used to heat the fabric into nonwoven fabrics.

Spunbonded nonwoven fabric has many advantages, such as aeration and water permeability. It is widely used in agriculture and animal husbandry.

D. stitched knit fabric refers to the unstitched fabric net, which is stitched by multi head sewing machine to make it a more compact nonwoven fabric.

These fabrics are similar to the appearance and properties of traditional clothing materials and are widely used.

And artificial fur cloth, lint and so on.

2 yarn type stitched knit fabric

(1) yarn layer - stitched yarn type stitched nonwoven fabric is made of warp and weft yarn, and stitched yarns are knitted by flat weave to reinforce the yarn non woven fabric.

The appearance of the fabric and organic fabric and knitted fabric has good dimensional stability and high strength, and is suitable for outer garment fabrics.

(2) yarn layer - Terry stitched woven non-woven fabric, weft yarn is stacked into mesh, reinforced by stitched chain formed by stitched yarns.

Terry yarns are segmented with weft insertion in the stitched area to make the fabric appear uplift.

It can be used for decorative cloth, clothing materials, etc.

Its products have been widely used in many fields such as civil clothing, decorative cloth, industrial cloth, medical materials and military workers and high cutting edge technology. There are several hundred kinds of products developed, such as clothing lining, curtains, medical and health care products, geotextiles, filter cloth, cushion, wall cloth, carpets, baby diapers, packaging materials and crop insulation shed and so on.
