Non-woven fabric composition structure

Non-woven products are rich in color, bright and lively, fashionable and environmentally friendly, versatile, beautiful and generous, with diverse patterns and styles, and are light, environmentally friendly, and recyclable. They are internationally recognized as environmentally friendly products that protect the earth's ecology. Suitable for agricultural film, shoemaking, tanning, mattresses, quilts, decoration, chemical, printing, automobile, building materials, furniture and other industries, as well as clothing interlining, medical and sanitary disposable surgical gowns, masks, caps, bed sheets, hotels Disposable tablecloths, beauty, sauna and even today's fashionable gift bags, boutique bags, shopping bags, advertising bags and so on. Environmentally friendly products, versatile and economical.

Non-woven fabric characteristics:

Non-woven fabric is a kind of non-woven fabric, which directly uses polymer chips, short fibers or filaments to form fibers through airflow or mechanical netting, and then undergo hydroentangling, needle punching, or hot rolling reinforcement, and finally finishing The resulting non-woven fabric. A new type of fiber product with soft, breathable and flat structure. The advantage is that it does not produce fiber debris, is strong, durable, silky soft, and has a cotton feel. Compared with cotton fabrics, non-woven bags are easy to shape, and The cost is cheap.

Features of non-woven fabrics: durable, disposable. Insulating and conductive. Softness and stiffness. Density and expansion. Isotropic, anisotropic. Filterability, breathable and impermeable. Elasticity and stiffness. Light, loose and warm. Thin as a cicada's wings, thick as felt. Waterproof and breathable. Ironing, stitching, and compression molding. Flame retardant and antistatic. Water-permeable, waterproof, abrasion-resistant, and flocking. Wrinkle resistant, good elasticity, high moisture absorption, water repellency.

1. Lightweight: Polypropylene resin is used as the main raw material for production. The specific gravity is only 0.9, only three-fifths of cotton. It is fluffy and feels good.

2. Softness: It is composed of fine fibers (2-3D) and is formed by light-point hot-melt bonding. The finished product is moderately soft and comfortable.

3. Water-repellent and breathable: Polypropylene slices do not absorb water, have zero moisture content, and have good water-repellent properties. They are composed of pure fibers and are porous and air-permeable. It is easy to keep the cloth dry and easy to wash.

4. Non-toxic and non-irritating: The product is produced with FDA food-grade raw materials, does not contain other chemical components, has stable performance, is non-toxic, non-odor, and does not irritate the skin.

5. Antibacterial and anti-chemical agents: Polypropylene is a chemically blunt substance, not moth-eaten, and can isolate the corrosion of bacteria and insects in the liquid; antibacterial, alkali corrosion, and the strength of the finished product will not be affected by erosion.

6. Antibacterial property. The product is water-repellent, does not mold, and can isolate the erosion of bacteria and insects in the liquid, and is not moldy.

7. Good physical properties. It is made of polypropylene spun yarn directly spread into a net and thermally bonded. The product strength is better than ordinary staple fiber products, the strength is non-directional, and the vertical and horizontal strengths are similar.

8. In terms of environmental protection, the raw material of most of the non-woven fabrics currently used is polypropylene, while the raw material of plastic bags is polyethylene. Although the names of the two substances are similar, their chemical structures are far apart. The chemical molecular structure of polyethylene is very stable and extremely difficult to decompose, so it takes 300 years for plastic bags to be decomposed; while the chemical structure of polypropylene is not strong, the molecular chain can easily be broken, which can be effectively degraded , And enter the next environmental cycle in a non-toxic form, a non-woven shopping bag can be completely decomposed within 90 days. Moreover, the non-woven shopping bag can be reused more than 10 times, and the pollution degree to the environment after disposal is only 10% of the plastic bag.

According to different production processes, non-woven products can be divided into:

1. Spunlace non-woven fabric: The spunlace process sprays high-pressure fine water onto one or more layers of fiber webs to entangle the fibers with each other, so that the fiber webs can be reinforced and have a certain strength.

2. Thermally bonded non-woven fabric: Thermally bonded non-woven fabric refers to the addition of fibrous or powdery hot-melt bonding reinforcement materials to the fiber web, and the fiber web is heated, melted and cooled to reinforce into a cloth.

3. Pulp air-laid non-woven fabric: Air-laid non-woven fabric can also be called dust-free paper and dry paper-making non-woven fabric. It uses air-laid technology to open the wood pulp fiberboard into a single fiber state, and then uses air-flow method to agglomerate the fibers on the web curtain, and then reinforce the fiber web into a cloth.

4. Wet-laid non-woven fabrics: Wet-laid non-woven fabrics are used to open fiber raw materials placed in an aqueous medium into single fibers, and at the same time mix different fiber raw materials to form a fiber suspension slurry, which is transported to a web forming mechanism. The fibers are formed into a net in a wet state and then reinforced into a cloth.

5. Spunbond non-woven fabric: Spunbond non-woven fabric is formed after the polymer has been extruded and stretched to form continuous filaments. Adhesive or mechanical reinforcement method to make the web into a non-woven fabric.

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

7. Needle-punched non-woven fabric: Needle-punched non-woven fabric is a kind of dry-laid non-woven fabric. Needle-punched non-woven fabric uses the piercing effect of needles to reinforce the fluffy web into a cloth.

8. Stitched non-woven fabric: Stitched non-woven fabric is a kind of dry-laid non-woven fabric. The stitching method uses the warp-knitted loop structure to align the fiber web, yarn layer, and non-woven materials (such as plastic sheet, plastic thin film). Metal foil, etc.) or their combination is reinforced to make a non-woven fabric.
