What you should know about non-woven fabrics

2018-12-14 Page view : 138 views

Non – woven fabric ( non – woven fabric ) is a kind of fabric formed without spinning and weaving. It is formed by orienting or randomly arranging short textile fibers or filaments to form a web structure and then reinforcing it by mechanical, thermal or chemical methods.

Simply put, it is not made up of yarns interwoven and knitted together, but the fibers are bonded together directly by physical means, so when you get the sticky weight in your clothes, you will find that you can’t pull out the thread ends.

Characteristics of non-woven fabrics

The non-woven fabric has no warp and weft, is very convenient to cut and sew, and is light in weight and easy to shape. Non – woven fabric breaks through the traditional textile principle and has the characteristics of short technological process, fast production rate, high yield, low cost, wide use and many sources of raw materials.

Advantages

1 light weight

With polypropylene resin as the main raw material, the specific gravity is only 0.9, only three-fifths of that of cotton, with fluffiness and good hand feeling.

Soft

It consists of fine fibers ( 2 – 3d ) and is formed by light hot melt bonding. The finished product is moderate in softness and comfortable.

3 water, breathable

Polypropylene chips do not absorb water, the water content is zero, the finished product has good water repellency, is made up of 100 % fiber, has good air permeability, and is easy to keep the cloth surface dry and easy to wash.

4 non – toxic, non – irritating

The product is made of food-grade raw materials conforming to FDA, does not contain other chemical components, has stable performance, is non – toxic, does not have peculiar smell, and does not irritate skin.

5 anti-chemical agents

Polypropylene is a chemically inert substance, not moth – eaten, and can isolate bacteria and insects in the liquid.

Antimicrobial activity

The product is water – extractable, not moldy, and can isolate the corrosion of bacteria and insects in the liquid, not moldy.

7 good physical properties

It is made from polypropylene spinning directly laid into a net and thermally bonded. The strength of the product is better than that of common staple fiber products, with no directional strength and similar longitudinal and transverse strength.

Environmental protection
YP-PP-SMMS spunmelt nonwoven fabric production line Product Description
In terms of environmental protection, polypropylene is the raw material of most non-woven fabrics used, while polyethylene is the raw material of plastic bags. Although the two materials have similar names, their chemical structures are far apart. The chemical molecular structure of polyethylene has very strong stability and is extremely difficult to degrade, so it will take 300 years for the plastic bag to decompose. However, the chemical structure of polypropylene is not firm, and the molecular chain can be easily broken, so that it can be effectively degraded, and enter the next environmental cycle in a non-toxic form, and a non-woven shopping bag can be completely decomposed within 90 days. Moreover, the non-woven shopping bags can be reused more than 10 times, and the pollution to the environment after being discarded is only 10 % of that of plastic bags.
