Nonwoven Fabric is a fabric-like materialmade from long fibers, bonded together bychemical, mechanical, heat or solventtreatment. The term is used in the textilemanufacturing industry to denote fabrics,such as felt, which are neither woven norknitted. Nonwoven materials typically lackstrength unless densified or reinforced by abacking.

Nonwoven fabrics are broadly defined as sheet or web structures bonded together by entangling fiber or filaments (and by perforating films) mechanically, thermally, or chemically. They are flat, porous sheets that are made directly from separate fibers or from molten plastic or plastic film.

Nonwovens have specific characteristics that allow them to deliver

high-performance across a wide range of applications. Specific

functions include:

- Absorbency - liquid repellency

- Resilience - stretch

- Softness - strength

- flame retardancy - wash ability (selective

products),

- Cushioning - filtering

- bacterial barrier and sterility

First, spunlace non-woven fabric Spunlaced process is high-pressure micro flow injection into a

layer or layers of fibrous web, so that the fibers are twisted together, so that the web can be strengthened and have a certain strength.

Second, a non-woven fabric Thermal bonded nonwovens is defined in the web of fibrous or

powder adding hot-melt adhesive reinforcement material, web after heating melt cooling reinforcement into cloth.

Third, pulp airlaid nonwoven fabric Air-laid non-woven fabrics can be called clean paper, paper non-

woven fabrics. It is the use of airlaid pulp fiber plate technology will be opening a single fiber state, and then use the airflow method of making fiber agglutination in a curtain net, web reinforcement into cloth.

Fourth, wet nonwoven fabrics

Wet nonwoven fabric is placed in water medium fiber opening into single fibers, while the different fiber raw material mixing, into the fiber suspension slurry, suspension slurry to web forming mechanism, fiber in wet state into the net reinforcement into cloth.

Fifth, spunbonded nonwoven fabric Spunbonded nonwoven fabric is in the polymer has

been extruded, stretched and form a continuous filament, filament laying into the net, the web through the self bonding, thermal bonding, chemical bonding or mechanical reinforcement method, make the web into a non-woven fabric.

Nonwovens are used effectively for optimisingthe productivity of crops, gardens and greenhouses. Their protective nature means that the need for pesticides is reduced and manual labour is kept to a minimum.

Filter cartridges, filter plates, filter bags and Eco-Protect safety filters for industrial dust removal applications, with high-performance filter media made of nonwovens.

Nonwoven textiles play a significant role in the medical sector. The product range includes surgical gowns, masks and other wearable products; surgical drapes, pads; dressings; filtration materials; and implantable textiles such as tissue scaffolds for rebuilding internal organs, among other products.

By far, most nonwoven products used outside the body are disposable, single-use articles that have the advantage of not requiring sterilization or cleaning for reuse. However, there are some that can be reused to provide the required function over a limited period of time.

The U.S. Marine Corps has taken the initiative todevelop state-of-the-art nonwoven compositefabric technology for use as alternate fabricapplication for Combat Utility Uniforms (CUUs),equipment and shelters. This effort is beingconducted via a Small Business InnovativeResearch (SBIR) contract. Essentially, SBIRs arevery competitive and offer the perfect mediumin which to conduct what may be termed High-

Risk-Technology.

• Nonwovens for filtering coolants and lubricants, as well as washing, phosphating and coagulation baths in the metal-processing industry.

• Membrane support nonwovens for filtering fruit juices, enzymes, electro-dip coating and effluents.

The use of nonwovens has increased substantially in recent years. Today more than 40 automotive parts are made with nonwoven fabrics, from trunk liners and carpets to air and fuel filters. By building in the essential properties which are necessary for good performance and safety, nonwovens help reduce the weight of the car, enhance the comfort and aesthetics and provide advanced insulation, fire retardancy and resistance to water, fuels, extremes of temperature and abrasion.

Anti-radiation-type construction textiles will be very important in the future.

- Foil, a special film, combined with materials such as foam thermal insulation products

- Sound insulation

A broad spectrum of applications including:

- liners, - counter liners, - inter-liners and - reinforcing materials

Membranes and insoles ensure a healthy foot climate and a high degree of foot comfort.

Global society will grow older. (adult ages 65+ will be %17)UN - Global society will organize itself along networks of shared

interests that increasingly disregard physical and temporal boundaires.

- The rise of the global middle class (GMC) will create new demands on the nonwovens and related industries, its operations and related industries.

- Obese ( USA %80, ENGLAND%70, BRAZIL%60, S.AFRICA, and CHINA %50 in 2030) WHO

- Climate change, resource scarcity and relativly high oil prices will lead to the introduction of new corporate social responsibility (CSR) standarts on all producers.

The worldwide use of nonwoven fabric is increasing day-by-day and this large market is controlled by the few number of countries. In that case, Bangladesh has large opportunity to capture this huge market by establishing a significant number of nonwoven fabric industries in Bangladesh. We have goodwill in ready-made garments and over all textile product sectors & by using this goodwill we can easily create a market for non-woven products.

Thank You!
