Non-woven fabrics of 7 categories, wonderful processing and manufacturing technology

Non Woven Fabric

Nonwoven cloth (also known as Nonwoven Fabric) is composed of directional or random fibers.It is called cloth because of its appearance and certain properties.

Simply put, it is not made of yarn interwoven and braided together, but by means of physical or chemical bonding of the fibers together, so that when you get the scale in your clothes, you will find that there is no thread to be pulled out.

One, the characteristics of non-woven fabric

Non-woven fabric has no warp and weft, so it is very convenient to cut and sew, and it is light and easy to shape.Nonwovens break through the traditional textile principle, and have the characteristics of short technological process, fast production rate, high output, low cost, wide use and many sources of raw materials.

Non Woven Fabric

It has poor strength and durability compared to textile fabrics and cannot be washed like other fabrics.Because the fibers are arranged in a certain direction, they tend to split at right angles, etc., so the improvement of production methods mainly focuses on the improvement of preventing splitting.

The classification of non-woven fabrics

Non-woven fabrics can be divided into:

 Spunlace Nonwoven

Is the high pressure micro water jet to a layer or multi-layer of fiber network, so that the fiber entangled with each other, so that the fiber network can be strengthened and have a certain strength.

Spunlace Nonwoven

Features:

1. Flexible tangles do not affect the original characteristics of the fiber and do not damage the fiber.

2. The appearance is more similar to traditional textiles.

3. High strength and low fuzz.

4. High hygroscopicity, fast hygroscopicity.

5. Soft hand and good drape.

6. Varied appearance.

7. Long production process and large area.

8. Complex equipment, large energy consumption and high water quality requirements.

Application: medical curtain, surgical clothing, surgical cover cloth, medical dressing materials, wound dressings, medical gauze, aviation dishcloth, clothing lining cloth, coating cloth, advanced dishcloth in electronic industry, cosmetic cotton, wet towel, mask covering material, etc.

◆ thermal bonded non-woven fabric

It refers to the addition of fiber or powdery hot melt bonding reinforcement material in the fiber network, the fiber network through heating melt cooling reinforcement into cloth.

Nonwoven

Features:

Surface bonding hot rolling surface more smooth, point bonding hot rolling relatively fluffy.

Application: produce diaper and sanitary napkin covering material, ointment base cloth, clothing lining, mask, etc.

◆ pulp flow into a net non - woven fabric

Can also be called dust-free paper, dry papermaking non-woven cloth.It is the use of air into the network technology to open the wood pulp fiberboard into a single fiber state, and then use the air method to make the fiber agglutination in the screen into a mesh, fiber mesh and then reinforcement into cloth.

Nonwoven

Features: good pompadour, soft feel, super moisture absorption.

Application: medical sanitary materials, especially disposable sanitary products with high water absorption (such as diapers, sanitary towels, wet face towels, cleaning cloth, etc.).

◆ wet non-woven fabric

It is to open the fiber raw materials in the water medium into a single fiber, and at the same time make different fiber raw materials to mix, into the fiber suspension pulp, suspension pulp transport to the mesh mechanism, the fiber in the wet state into the mesh and then strengthen into cloth.

Nonwoven

Features:

1. High production speed, up to 400m/min.

2. Take full advantage of staple fibers.

3. Product fiber mesh uniformity is good.

4. Large water consumption and high one-time investment.

Product application:

1. Special paper: dust/liquid filter paper, tea bag.

Industrial use: filter, insulation material, sound-absorbing material.

3. Medical use: medical backing, medical tape, surgical package materials.

4. Civilian use: wallpaper, etc.

Spun viscose nonwoven fabric

Is in the polymer has been extruded, stretched and formed a continuous filament, filament laid into a network, fiber mesh through its own bonding, thermal bonding, chemical bonding or mechanical reinforcement method, so that the fiber mesh into non-woven fabric.

Nonwoven

Features:

1. Fiber mesh consists of continuous filament.

2. Excellent tensile strength.

3. There are many changes in the process, which can be reinforced by a variety of methods.

4. Wide variation range of filament fineness.

Product application:

1. Polypropylene (PP) : geotechnical cloth, tufted carpet base cloth, coating undercloth, medical material, and coating material of disposable products, etc.

2. Polyester (PET) : filter materials, lining materials, tufted carpet substrate, agricultural materials, packaging materials, etc.

◆ melt-blown non-woven fabric

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

Nonwoven

Features:

1. Fiber mesh consists of very fine shorter fibers.

2 fiber mesh uniformity is good, soft feel.

3. Good filtration and liquid absorption performance.

4. Poor strength of fiber mesh.

Application: filter material, medical material, clothing material, battery diaphragm material, wiping material.

◆ needled non-woven fabric

Is a kind of dry non-woven fabric, needling non-woven fabric is the use of needle puncture, will be fluffy fiber mesh reinforcement into cloth.

Nonwoven

Features:

1. Flexible entanglement between fibers, with good dimensional stability and elasticity.

2. Good permeability and filtration performance.

3. It feels plump and fluffy.

4. Can manufacture various collection patterns or three-dimensional molding products according to requirements.
