Something About Spunbond Non Woven

1. The production principle and characteristics of Spunbond non woven

Spunbond non woven extrudes and stretches the polymer to form continuous filaments, the filaments are laid into a web, and the web is then self-bonded, thermally bonded, chemically bonded or mechanically reinforced to make the web into a non-woven fabric. spinning.

Features Good high temperature resistance, good high temperature resistance (polypropylene can be used for a long time at 150 °C, polyester can be used for a long time at 260 °C), aging resistance, UV resistance, high elongation, good stability and air permeability, resistance Corrosion, sound insulation, moth proof, non-toxic.

2. Main materials and uses of Spunbond non woven

The main products of Spunbond non woven are polypropylene and polyester (long fiber, staple fiber) non-woven fabrics. Our most common and commonly used applications are non-woven bags, non-woven packaging, etc.; for the identification of spunbond non-woven fabrics It is relatively easy, and the two-way fastness is generally good. Generally, the nip point of the spunbond non-woven fabric is diamond-shaped.

At the application level, it can also be used as flower packaging cloth, luggage cloth, etc. The characteristics of wear resistance, firm hand feeling, etc. make it the best choice for making such products.

3. Maintenance and collection of Spunbond non woven

The following points should be paid attention to in the maintenance and collection of Spunbond non woven:
a. Keep it clean and wash it frequently to prevent the growth of moths.

b. When storing in different seasons, it must be washed, ironed, dried, sealed in a plastic bag, and placed flat in the wardrobe. Pay attention to shading to prevent fading. It should be often ventilated, dusted and dehumidified, and not exposed to the sun. Mildew-proof and moth-proof moths should be placed in the wardrobe to prevent cashmere products from being damp and mouldy.

c. When worn inside, the matching coat lining should be smooth, and hard objects such as pens, key cases, mobile phones, etc. should not be placed in the pockets to avoid local friction and pilling. Minimize friction with hard objects (such as sofa backs, armrests, table tops) and hooks when wearing them. It is not easy to wear for too long, and it must be stopped or changed for about 5 days to restore the elasticity of the clothes to avoid fiber fatigue damage.

d. If there is pilling, do not pull it forcibly. Use scissors to cut off the pom-pom, so as not to be repaired due to off-line.
In addition, spunbond non-woven fabrics are divided into hydrophilic and water-repellent. What is going on? Hydrophilic non-woven fabric: Hydrophilic, as the name implies, is "hydrophilic" and has strong adsorption to liquids. (such as baby diapers,diaper non woven) Water-repellent non-woven fabrics: Contrary to the properties of hydrophilic non-woven fabrics, the surface tension of the fibers is reduced after chemical treatment, and the liquid cannot wet the surface. (such as surgical gowns, protective clothing, etc.), non-woven fabrics are also divided into general anti-, tertiary, and high-resistance.
