Basic Knowledge Of Fabric Tutorial 1- What Is Non-Woven Fabric?

Because it is a kind of spinning.

The fabric formed is only a directional or random strut of textile staple fibers or filament, forming a web structure, and then reinforced by mechanical, thermal or chemical methods.

To put it simply,

It is not one by one.

They are woven together, but the fibers are directly bonded to each other through physical means. So when you get the sticky tape in your clothes, you will find that you can't get a thread out of it.

Nonwoven fabrics break through the traditional textile principle, and have the characteristics of short process flow, fast production speed, high output, low cost, wide use, and many sources of raw materials.

Its main uses can be roughly divided into:

(1) medical and health services: surgical gowns, protective clothing, disinfectant cloth, mask, diapers, sanitary napkins, etc.

(2) household decoration cloth: wall covering, tablecloth, sheets, bedspreads and so on;

(3) with the use of cloth: lining, adhesive lining, floc, stereotypes cotton, all kinds of synthetic leather cloth and so on;

(4) industrial cloth: filter materials, insulation materials, cement packaging bags, geotextiles, coated fabrics, etc.

(5) agricultural cloth: crop protection cloth, seedling raising cloth, irrigation cloth, thermal curtain, etc.

(6) others: Space cotton, thermal insulation and sound insulation materials, oil absorbing felt, cigarette filter, bag, tea bag and so on.

Non-woven fabrics

Classification:

Spunlaced Nonwovens

Spunlaced technology is to spray high pressure tiny water streams onto one or more layers of fiber network, so that fibers intertwine together, so that the mesh can be strengthened and has a certain strength.

Two, heat bonded non-woven fabrics

Heat bonded non-woven fabric refers to the addition of fibrous or powdered hot melt adhesive to the mesh.

After heating and melting, the cloth is reinforced.

Three, pulp airflow mesh non-woven fabric

Air laid non-woven fabric can also be called dust-free paper and dry papermaking nonwovens.

It uses air net forming technology to break the wood pulp fiber board into a single fiber state, and then uses the airflow method to make the fiber agglomerate on the net curtain, and the mesh is further reinforced into cloth.

Four, wet non-woven fabrics

The wet non-woven fabric is loosened into single fiber by putting raw materials into the water medium. At the same time, different fiber materials are mixed and made into fiber suspension slurry. The slurry is pported to the mesh forming mechanism, and the fibers are reinforced into cloth under wet condition.

Five. Spunbonded nonwovens

Spunbonded nonwoven fabric is made of continuous filament after polymer has been extruded and stretched. The filament is laid into a mesh, and the mesh is made of non-woven fabrics through self bonding, thermal bonding, chemical bonding or mechanical reinforcement.

Six. Melt blown nonwovens

Melt blown non-woven process: polymer feeding - melt extrusion - fiber formation - fiber cooling - mesh - reinforcement cloth.

Seven.

Needle punched nonwoven fabric is a kind of dry non-woven fabric. Needle punched nonwoven fabric is made of punched needles, which is used to reinforce the fabric.

Eight, stitched woven non-woven fabrics

Stitched woven non-woven fabric is a kind of dry non-woven fabric. The stitching method is to use warp knitted coil structure to screen fiber mesh, yarn layer, and so on.

(for example, plastic sheets, plastic thin metal foil, etc.) or their combination to reinforce non-woven fabrics.
