Non-Woven

NON-WOVEN

The fabrics which are produced directly from bonding or entangling the fibres or filaments are called non-woven fabrics. The bonding is done by mechanical, ther-mal or chemical means. Non-woven can be divided into durable, non durable or disposable and semi durable types. The properties of non-woven fabrics vary because they are made with different type of fibres in different methods, depending upon the end product.

Types of Non-Woven

Non-woven are grouped based on the method of production and life of the fabric­. Based upon the production non-woven are grouped as felts and bonded fabrics.

Based on non-woven fabrics quality they are classified as durable, non durable, dis-posable and semi durable types. There are two main types of non-woven namely felts and bonded fabrics.

Felt fabrics are made by interlock-ing of fibres by any suitable mechanical or chemical method, with action of moisture and heat. The basic techniques of fabric construction like weaving, spinning and knitting are not used. Bonded fabric can be described as fibres compressed by pres-sure and heat.

The properties of non-woven fab-rics vary because they are made with dif-ferent types of fibres in different methods, depending upon the end product.

Uses of Non-Woven

Felts are used in home furnishing and bonded fabrics are used in sanitary pads and diapers. Durable non-woven are used for cap, interlining and interfacing for home furnishing, upholstery, carpets and filters. Disposable non-woven are fabric which can be used only once like diapers, sanitary

napkins, surgical and industrial masks, ban-dages and towels. Semi durable non-woven are used for shirts, curtains, bags, lining material, wicks backing fabrics for picture frames, ribbons, hospital bed linens and operation theatre clothes. (Figure 5.16)
