Polyester Non-woven Use And Classification
Jan 09, 2018

Polyester non-woven fabric belongs to one of non-woven fabrics, the name of non-woven fabric is called nonwoven fabric, or is called non woven fabric. Because it is a fabric that does not need spinning and weaving. It only orientate or staple textile staple fiber or filament to form fibrous structure. Then it is reinforced by mechanical, thermal or chemical methods.

The characteristics of non-woven fabric

Nonwovens break through the traditional textile principle, and have the characteristics of short process, fast production, high output, low cost, wide usage and raw material sources.

The use of non-woven fabrics

Its main uses can be roughly divided into:

(1) medical and health nonwovens: surgical clothing, protective clothing, disinfectant cloth, mask, diaper, toilet cloth, wipe cloth, wet towel, magic towel, soft towel roll, beauty products, sanitary napkin, sanitary pad and disposable sanitary cloth.

(2): home decoration with non-woven fabric with Qiangbu, tablecloth, bed sheet, bedspread etc.;

(3): clothing with non-woven lining, lining, interlining, setting cotton, various synthetic leather base cloth etc.;

(4) industrial non-woven fabrics; filter materials, insulating materials, cement bags, geotextiles, coated cloth and so on;

(5) agricultural non-woven fabrics: crop protection cloth, seedling raising cloth, irrigation cloth, heat preservation curtain and so on;

(6) other non-woven fabrics: Space cotton, insulation and sound insulation material, oil felt, smoke filter, bag bag tea bag and so on.

The types of non-woven fabrics can be classified according to the different production processes.

1, spunlaced nonwovens: high pressure tiny water flow to a layer or multi-layer fiber network, so that fibers intertwined together, so as to strengthen the fabric and have a certain strength.

2, hot metal nonwoven fabric: it refers to fiber or powdery hot melt adhesive reinforcement in the fiber net, and then the fiber net is reinforced by heating and melting to reinforce the cloth.

3, the pulp air flow into the net non-woven cloth: also can be called as dust free paper, dry paper non-woven fabric. It uses airflow net forming technology to break wood pulp fiberboard into single fiber state, and then uses airflow method to make fiber agglomerate on net curtain, and then reinforce the fabric into cloth.

4, wet nonwovens: the raw materials are loosened into single fibers in the water medium, and different fiber materials are mixed to make fiber suspension slurry. The suspended slurry is transported to the mesh forming mechanism, and the fibers are further reinforced into cloth under wet condition.

5, spunbonded nonwovens: after the polymer has been extruded and stretched to form continuous filament, the filament will be laid into mesh, and the mesh will be transformed into non-woven fabric through its own adhesion, thermal bonding, chemical bonding or mechanical reinforcement.

6, melt spray non-woven fabric: its process process: polymer feeding - melt extrusion - fiber formation - fiber cooling - Network - - reinforced into cloth.

7, non-woven cloth is a kind of dry non-woven, non-woven needle puncture needle is the effect of fiber net, fluffy reinforcement into cloth. 8, stitched woven non-woven fabric: one is dry non-woven fabric, and stitching is reinforced by warp knitting coil structure, such as mesh, yarn layer, non-woven material, such as plastic sheet, plastic thin metal foil or their combination, to make non-woven fabrics.
