What are the classifications and uses of non-woven fabrics?

Classification of non-woven fabrics

1、 Heat sealed non-woven fabric

Hot bonded non-woven fabric refers to adding fibrous or powdery hot melt adhesive reinforcement materials to the fiber web, and then heating, melting, and cooling the fiber web to reinforce it into a fabric.

2、 Pulp air laid non-woven fabric

Airflow nonwoven fabric, also known as dust-free paper or dry papermaking nonwoven fabric. It uses air flow web technology to loosen wood pulp fiberboard into a single fiber state, and then uses air flow method to aggregate the fibers on the web curtain, and the fiber web is reinforced into fabric.

3、 Water jet non-woven fabric

The water jet process is to spray high-pressure fine water onto one or more layers of fiber webs, causing the fibers to entangle with each other, thereby reinforcing the fiber webs and giving them a certain strength.

4、 Wet non-woven fabric

Wet non-woven fabric is made by loosening fiber raw materials placed in an aqueous medium into single fibers, and mixing different fiber raw materials to produce fiber suspension slurry. The suspension slurry is transported to the web forming mechanism, and the fibers are formed into a web in a wet state and then reinforced into fabric.

5、 Melt blown non-woven fabric

The process of melt blown non-woven fabric: polymer feeding - melt extrusion - fiber formation - fiber cooling - web formation - reinforcement into fabric.

6、 Needle punched non-woven fabric

Needle punched non-woven fabric is a type of dry non-woven fabric that utilizes the puncture effect of needles to reinforce fluffy fiber webs into fabric.

7、 Spunbond non-woven fabric

Spunbond nonwoven fabric is formed by extruding and stretching polymers into continuous filaments, which are then laid into a web. The web is then self bonded, thermally bonded, chemically bonded, or mechanically reinforced to transform into nonwoven fabric.

8、 Stitching non-woven fabric

Stitching non-woven fabric is a type of dry non-woven fabric, which uses a warp knitted coil structure to reinforce fiber webs, yarn layers, non-woven materials (such as plastic sheets, plastic thin metal foils, etc.) or their combinations to produce non-woven fabric.

Its main uses can be roughly divided into:

1. Non woven fabrics for clothing: lining, adhesive lining, floc, shaping cotton, various synthetic leather base fabrics, etc;

2. Industrial non-woven fabric; Filter materials, insulation materials, cement packaging bags, geotextiles, wrapping fabrics, etc;

3. Medical and hygiene non-woven fabrics: surgical gowns, protective clothing, disposable disinfectant non-woven bags, masks, diapers, household cloths, wiping cloths, wet wipes, magic towels, soft tissue rolls, beauty products, sanitary napkins, sanitary pads, and disposable sanitary cloths, etc;

4. Non woven fabrics for home decoration: wall coverings, tablecloths, bed sheets, bedspreads, etc;

5. Agricultural non-woven fabrics: crop protection cloth, seedling raising cloth, irrigation cloth, insulation curtains, etc;

6. Other non-woven fabrics: space cotton, insulation and soundproofing materials, oil absorbing felt, cigarette filters, tea bags, etc.
