Non-woven fabrics
Nonwovens are engineering fabrics made of fibers, continuous filaments or cut yarns. They are flexible, porous products consisting of one or more fiber layers. Individual fibers can be preferentially oriented in one direction or deposited randomly. Nonwovens are chemically, thermally or mechanically bonded to textiles. They are mainly plane structures.

Nonwoven fabric
The characteristics of non-woven fabrics may have specific characteristics depending on the combination of factors in their production. It has a wide range of features.
1. The appearance of non-woven fabric can be paper similar to or similar to woven fabric, feeling paper or similar paper.
2. They may have a soft, elastic hand, or they may be hard, stiff or broad, with little flexibility.
3. They may be as thin as tissue paper, or they may be very thick.
4. They can also be translucent or opaque.
5. Their porosity can range from low tear strength and antiknock strength to very high tensile strength.
6. They can be made by gluing, hot gluing or stitching.
7. The drape of this type of fabric varies according to different conditions.
8. Some fabrics have excellent washability; others don't. Some can be dry cleaned.
Non woven fabrics are designed to provide specific properties suitable for the desired end use. For example, a diaper may consist of two different layers of non-woven fabric: an outer layer consisting of a wetting agent treated polyester that allows rapid fluid penetration, but with minimal lateral wicking, and an inner layer that absorbs rayon. Thin high filter nonwovens for surgical masks can be made of tiny fibers; thick, fluffy, insulating nonwovens for ski jackets can also be made of tiny denier fibers. Further research is carried out to achieve or possibly surpass some characteristics of the traditional fabric.
End use of non-woven fabrics
The use of non-woven products continues to expand. Many uses of non-woven fabrics can be divided into disposable products, durable consumer goods and industrial materials. All these areas are increasingly using this commodity because of its low cost and applicability to many needs.
Disposable non-woven fabrics are basically disposable; however, some, such as dust cloth, may be washed and reused several times.
General applications include personal hygiene products such as diapers and sanitary napkins; medical products such as surgical gowns and curtains; surgical and industrial masks, bandages, rags and towels; bibs and even clothing for special events. They have recently become popular with lightweight "fun" cloth that can be washed several times. Durable non-woven fabric is widely used. Durable consumer goods include household and household goods such as drapery, upholstery, mattress padding, towels, tablecloths, blankets and carpet backing, clothing and clothing such as hats, linings, linings, seams and other fabric reinforcement. Many industrial applications include filters, insulation, packaging materials, subgrade stabilizers or road building materials, Geotextiles and roofing products.
Special non-woven products:
Fusible nonwovens: fusible nonwovens are any nonwovens with a resin coating of a thermally activated adhesive. More than half of the wiring used in clothing buildings is wireable. They are placed between clothes that lift Ayers to provide body, shape, and support for extra strength and foundation. Apply heat and pressure for a period of time to activate the resin to bond the interface to the shell fabric.
The fusible interface has some disadvantages. They sometimes produce stiff hands and feet; the difference between the joined fabrics shrinks to produce corrugated clothing; and when the improperly applied interface is cleaned, the separation of the two fabric layers can occur.
Other special nonwovens include film cloth, artificial suede and leather.
