The characteristics and applications of 7 kinds of non-woven fabrics

Non Woven Fabric (English name: Non Woven Fabric or Nonwoven cloth), also known as non-woven fabric, is composed of directional or random fibers. It is called cloth because of its appearance and certain properties.

Simply put: it is not interwoven and braided by yarns one by one, but the fibers are directly bonded together by physical or chemical methods, so when you When you get the sticky scale in your clothes, you will find that it is impossible to extract a single thread.

First, the characteristics of non-woven fabrics

Non-woven fabrics have no warp and weft threads, so cutting and sewing are very convenient, and they are light and easy to shape. Nonwovens break through the traditional textile principles, and have the characteristics of short process flow, fast production rate, high output, low cost, wide application, and many sources of raw materials.

It is less strong and durable than woven fabrics and cannot be cleaned like other fabrics. Because the fibers are arranged in a certain direction, it is easy to split at right angles, etc., so the improvement of the production method is mainly focused on the improvement of preventing splitting.

Second, the classification of non-woven fabrics

Non-woven fabrics can be divided into:

◆Spunlace non-woven fabrics

It is to spray high-pressure fine water flow onto one or more layers of fiber webs, so that the fibers are entangled with each other, so that the fiber webs can be reinforced and have a certain strength.

Features:

1. Flexible entanglement, does not affect the original characteristics of the fiber, and does not damage the fiber.

2. The appearance is closer to traditional textiles.

3. High strength and low fluff.

4. High hygroscopicity, quick hygroscopicity.

5. Soft hand feel and good drapability.

6. The appearance is varied.

7. The production process is long and covers a large area.

8. The equipment is complex, the energy consumption is large, and the water quality requirements are high.

Product application: medical curtains, surgical gowns, surgical cover cloths, medical dressing materials, wound dressings, medical gauze, aviation rags, clothing lining fabrics, coated fabrics, advanced rags in the electronics industry, cosmetic cotton , wipes, mask covering materials, etc.

◆Heat-bonded non-woven fabrics

It refers to adding fibrous or powdery hot-melt adhesive reinforcement materials to the fiber web, and the fiber web is then heated, melted, cooled, and consolidated into a cloth.

Features:

The surface of the surface bonding hot rolling is relatively smooth, and the point bonding hot rolling is relatively fluffy.

Product application: production of baby diapers and women's sanitary napkin covering materials, ointment base cloth, clothing lining, masks, etc.

◆Pulp airlaid non-woven fabrics

Also known as dust-free paper and dry-laid non-woven fabrics. It uses the air-laid technology to open the wood pulp fiberboard into a single fiber state, and then uses the air-laid method to condense the fibers on the web-forming curtain, and the fiber web is then reinforced into a cloth.

Features: good bulkiness, soft hand feel, and super hygroscopic performance.

Product application: medical hygiene materials, especially disposable hygiene products with high water absorption (such as diapers, sanitary napkins, wet face wipes, wipes, etc.).

◆Wet-laid non-woven fabrics

The fiber raw materials placed in the water medium are opened into single fibers, and different fiber raw materials are mixed at the same time to make fiber suspension pulp. The pulp is transported to the web forming mechanism, and the fibers are formed into a web in the wet state and then consolidated into a cloth.

Features:

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

2. Short fibers can be fully utilized.

3. The uniformity of the fiber web of the product is better.

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

Product application:

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

2. Industrial use: filters, insulating materials, sound-absorbing materials.

3. Medical use: medical backing, medical tape, surgical bag wrapping material.

4. Civil: wallpaper, etc.

◆Spunbond non-woven fabrics

After the polymer has been extruded and stretched to form continuous filaments, the filaments are laid into a web, and the web is then self-bonded. Bonding, thermal bonding, chemical bonding or mechanical reinforcement methods to turn the web into a non-woven fabric.

Features:

1. The fiber web is composed of continuous filaments.

2. Excellent tensile strength.

3. There are many technological changes, and various methods can be used for reinforcement.

4. The variation range of filament fineness is wide.

Applications:

1. Polypropylene (PP): geotextiles, tufted carpet base fabrics, coated base fabrics, medical and health materials, covering with disposable products materials, etc.

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

◆Melt-blown non-woven fabric

Process of melt-blown non-woven fabric: polymer feeding---melt extrusion---fiber formation---fiber cooling- -- Forming into a net --- Reinforcing into a cloth.

Features:

1. The fiber web is composed of extremely fine short fibers.

2. The uniformity of the fiber web is good and the hand feels soft.

3. Good filtration performance and liquid absorption performance.

4. The strength of the fiber web is poor.

Product application: filter materials, medical and health materials, clothing materials, battery separator materials, wiping materials.

◆Needle-punched non-woven fabric

It is a kind of dry-laid non-woven fabric. .

Features:

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

2. Good permeability and filtration performance.

3. Feel plump and fluffy.

4. Various collection patterns or three-dimensional molding products can be manufactured according to requirements.
