Flame retardant non-woven why flame retardant

I believe we have used non-woven fabrics, moisture-proof, breathable, flexible, non-combustion, easy decomposition, rich color, low price, recycling and other characteristics.

Among the non-woven fabrics, there is a flame retardant non-woven fabrics, with high strength and elasticity, good heat resistance, smooth surface, corrosion resistance and other characteristics, so why can be flame retardant?

Flame-retardant non-woven fabric, also known as flame-retardant non-woven fabric, is a kind of fabric that does not need spinning and weaving. It is a thin sheet, fiber net or floc pad made by rubbing, binding or bonding of oriented or randomly placed fibers, or a combination of these methods.

The flame-retardant mechanism is primarily involved in flame-retardant agent, flame-retardant agent, is a kind of data with additives, usually used in polyester plastics, textiles, etc., coated with aluminum non-woven cloth added to polyester through improving the ignition point of data or prevent data burning to achieve the purpose of flame-retardant, and then improve the fire safety of data.

Flame retardant non-woven fabrics can be divided into three categories according to the raw materials: polyester flame retardant non-woven fabrics, polypropylene flame retardant non-woven fabrics and viscose flame retardant non-woven fabrics.

This is mainly in accordance with their primary components of non-woven no warp and weft, cutting and sewing are very convenient, and light and easy to finalize the design, favored by handmade enthusiasts.

Because it is a kind of fabric that does not need spinning and weaving, it is made by directional or random arrangement of textile staple fibers or filament to form fiber mesh structure, and then reinforced by mechanical, thermal bonding or chemical methods.

It is not interwoven and braided together from yarn to yarn, but the fibers are physically bonded together so that when you get the scale in your clothes, you will find that you cannot pull out the threads.

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.

The relationship between non-woven and spun-bonded fabrics

Spun-bonded and non-woven fabrics are dependent.

There are many production processes in the manufacture of non-woven fabrics, among which spunbond method is one of them

Spunbonded non-woven fabric

(including spun-bonded, melt-blown, hot-rolled and spun-spined, most non-woven fabrics produced by spun-bonded are in the market now)

Non-woven fabrics according to the composition, polyester, polypropylene, nylon, spandex, acrylic, etc.

Different ingredients will have completely different non-woven style.

And spunbonded cloth, usually refers to polyester spunbonded, polypropylene spunbonded;

The styles of the two cloths are so close that they can only be distinguished by high temperature tests.

Nonwoven fabric is a kind of nonwoven fabric, which is directly using polymer slices, short fibers or filament fibers through the air flow or mechanical network, and then through spines, needles, or hot rolling reinforcement, and finally after finishing the formation of non-woven fabric.

New fiber products with soft, breathable and flat structure have the advantages of no fiber scraps, strong, durable and silky soft. It is also a kind of reinforcing material. Besides, it also has the feel of cotton.



Light weight: polypropylene resin as the main raw material, proportion of only 0.9, only three fifths of cotton, fluffy, feel good.


Soft: composed of fine fiber (2-3D) light hot melt bonding molding.

The finished product has moderate softness and comfort.


Water and air permeability: polypropylene slice does not absorb water and has zero moisture content. The finished product is of good water quality. It is composed of 100% fiber with porosity and good air permeability.

Polypropylene nonwoven fabric


Non-toxic and non-irritating: the product is made of food grade raw materials in line with FDA, without other chemical ingredients, with stable performance, non-toxic, no peculiar smell and no skin irritation.


Antibacterial, anti-chemical agents: polypropylene is a chemical blunt material, no moth, and can isolate the existence of liquid bacteria and insect erosion;

Antibacterial, alkali corrosion, finished products do not affect the strength due to erosion.


Antimicrobial properties.

Products with water extraction, mildewy, and can isolate the existence of liquid bacteria and insects erosion, mildewy moth.


Physical properties.

The product is made of polypropylene spinning and directly spread into mesh thermal bonding. The strength of the product is better than that of general staple fiber products.


In terms of environmental protection, the raw material of most non-woven fabrics used is polypropylene, while the raw material of plastic bags is polyethylene. Although the names of the two substances are similar, they are far from each other in chemical structure.

The chemical molecular structure of polyethylene is quite stable and difficult to degrade, so it takes 300 years to decompose plastic bags.

The chemical structure of polypropylene is not strong, and the molecular chains can easily break, which can degrade effectively and enter the next environmental cycle in the non-toxic form. A non-woven shopping bag can be completely decomposed in 90 days.

In addition, the non-woven shopping bag can be reused for more than 10 times, and the pollution to the environment after waste is only 10% of the plastic bag.


1) poor strength and durability compared with textile fabrics.

2) cannot be washed like other fabrics.

3) fibers are arranged in a certain direction, so they tend to split at right angles, etc.

Therefore, the improvement of production methods mainly focuses on the improvement of preventing separation.
