1. Flame-retardant non-woven fabrics are classified by material:
(1) According to their main components, they can be divided into three levels: polyester flame-retardant non-woven fabrics, polypropylene flame-retardant non-woven fabrics and viscose flame-retardant non-woven fabrics.
1. The main component of polyester flame-retardant non-woven fabric is polyester. Polyester fiber is a chemical fiber and is a polymerization product of terephthalic acid or diethyl terephthalate and ethylene glycol.
Features: high strength, good elasticity, good heat resistance, smooth surface, good abrasion resistance, good light resistance, corrosion resistance and poor dyeability.
2. Polypropylene fiber is a synthetic fiber made from propylene
Features: High strength, good wet and dry strength, wear resistance and corrosion resistance.
3. Viscose fiber belongs to regenerated cellulose fiber
Features: It has good moisture absorption, lower breaking strength than cotton, environmental protection and non-toxic.
(2) Flame-retardant non-woven fabric can be divided into flame-retardant needle cotton and flame-retardant hot-air cotton according to the process.
The flame-retardant needle cotton is made of tangled fibers after being punctured by a needle punch
The flame-retardant hot-air cotton is mainly formed by the hot air passing through the furnace after laying the net.
Both products have their own characteristics. The common features are flame retardant, light weight, warmth, durability, and environmental protection.
The testing standards include American 16CFR1633, British BS5852 and American TB117, CA133 standards.
2. Introduction of flame-retardant cotton products
Flame-retardant cotton products have flame-retardant and anti-melt dripping effects, and can effectively form a flame-retardant firewall.
①The test content of 16CFR1633 in the United States: Within the 30-minute test time, the maximum heat release peak value of the mattress or mattress set shall not exceed 200 kilowatts (KW), and the total heat release must be within the first 10 minutes of release Less than 15 megajoules (MJ),
Material: Anfang flame retardant fiber (viscose fiber), 4080 fiber (low melting point fiber)
Purpose: Mainly used in mattresses, cushions, sofas, seats and home textile products.
②British BS5852 main test standards: mainly test cigarette butts and use acetylene flame to simulate matches for testing, as well as to see the damage length, basically use a lighter to burn vertically on the textile surface for 20 seconds, and within 12 seconds after leaving the flame, the flame will automatically Extinguished.
③Test content in USA 117: Cigarette test, the overfire part is not more than 80%, the average burnt length is not more than 3 inches, the maximum burnt length is not more than 4 inches, the average burning time is not more than 4 seconds, and the longest burning time is not more than 8 Second, the mass loss of open flame combustion does not exceed 4%.
Function: fire prevention
Purpose: Soft furniture, mattresses, toys, home textile products
Material: polyester fiber
3. Comparison of flame-retardant products
Features of products that can pass the American 16CFR1633 test: flame retardant, anti-melting, a small amount of smoke, no toxic gas, self-extinguishing effect, can maintain the original shape after carbonization, moisture absorption, breathability, soft touch, long-lasting elasticity, mainly suitable for Export high-end mattresses to the United States.
Features of products that have passed the BS5852 test standard: currently the European market has mandatory flame-retardant requirements for soft furniture, mattresses and seats. At the same time, it requires soft and hard hand feeling to be adjustable, good fire resistance, and automatically extinguished within 30 seconds, mainly applicable For export to the European market, high-end sofas are used more.
The characteristics of products that can pass the US TB117 test are relatively low among the three. The maximum burning time is no more than 8 seconds. It is suitable for textiles and furniture exported to the United States.
Weight: 40g/㎡～2000g/㎡
Width: 0.5m～3.2m
Thickness: 0.5cm～5cm
Product certification: TB-603, CFR-1633, UL-94.
Features: permanent flame retardant, moisture absorption, breathability, soft hand feeling, lasting elasticity, good heat insulation. When burning, there is only a small amount of smoke, no dripping, no release of poisonous gas, and has a self-extinguishing effect. It maintains its original shape after carbonization.
Application range: Mainly used in sofas, mattresses, clothing, etc. Name: ca133 flame-retardant cotton Applicable objects: upper sofa seats for public facilities, such as hotels, hotels, KTV and other public places. The production principle: polyester fiber, wool fiber, viscose fiber, after carding and netting, is mixed with low-melting fiber Become. Product features: white, soft, self-extinguishing and other features meet the American flame retardant testing standards.
Product features:
Weight: 100g/㎡～500g/㎡
Width: 0.5m～3m
Thickness: 0.5cm～5cm
Product certification: US CN-117, UK BS-5852, ROHS.
Features: Good tensile force, good resilience, environmental protection, strong fire resistance, no heavy metal content, loose quality, soft, comfortable hand feeling, not easy to be deformed by washing, and can be freely washed.
Judgment criteria: 1. The maximum heat release efficiency cannot exceed 80 kilowatts;
2. The total heat release in the first 10 minutes cannot exceed 25 MJ;
3. The time for the concentration of CO (carbon monoxide) released by the sample to exceed 1000 ppm cannot exceed 5 minutes;
4. The smoke density cannot exceed 75%.
Product advantages:
1. Pure white, soft hand feel, excellent elasticity, good moisture absorption and breathability.
2. Natural flame-retardant fiber is used, and there is no dripping phenomenon. Has a permanent self-extinguishing effect
3. A dense carbonized layer is formed during combustion. Low carbon monoxide and carbon dioxide content, only a small amount of non-toxic smoke
4. Stable acid and alkali resistance, non-toxic, and does not produce any chemical effects. The product can be degraded naturally, in line with environmental protection
◆Children's toys and family mattress textiles.
◆Decorative fabrics for vehicles and public places.
◆Work clothes, fire-proof clothing, heat-proof clothing lining.
