Classification of flame retardant non-woven fabrics by material
1. Classification of flame retardant non-woven fabrics by material:
(1) According to their main components, they can be divided into: polyester flame retardant non-woven fabric, polypropylene flame retardant non-woven fabric and viscose flame retardant non-woven fabrics.
1. The main component of polyester flame retardant non-woven fabric is polyester. Polyester fiber belongs to chemical fiber, which is the 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, poor dyeability.
2. Polypropylene fiber is a synthetic fiber made of propylene as raw material
Features: high strength, good wet and dry strength, wear resistance and corrosion resistance.
3. Viscose fiber belongs to regenerated cellulose fiber
Features: good hygroscopicity, lower breaking strength than cotton, environmentally friendly and non-toxic.
(2) Flame retardant non-woven fabrics can be divided into flame retardant needle cotton and flame retardant hot air cotton according to the process.
The flame retardant needle cotton is formed by entanglement of fibers after being punctured by a needle punching machine
The flame retardant hot air cotton is mainly formed by hot air passing through the furnace after laying the net.
Both products have their own characteristics, the commonality is flame retardant, light, warm, durable and environmentally friendly.
Testing standards include American 16CFR1633, British BS5852 and American TB117, CA133 standards.
II. Introduction of flame retardant cotton products
Flame retardant cotton products have the functions of flame retardant and anti-melt droplet, and can effectively form a flame retardant firewall.
①United States 16CFR1633 test content: During the 30-minute test period, the maximum caloric heat release peak of the mattress or mattress set shall not exceed 200 kilowatts (KW), and within the first 10 minutes of release, the total Heat release must be less than 15 megajoules (MJ),
Material: Anfang flame retardant fiber (viscose fiber), 4080 fiber (low melting point fiber)
Use: main 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, as well as the damage length, basically use a lighter to burn vertically on the textile surface for 20 seconds, and 12 seconds after leaving the flame inside, the flame goes out automatically.
③United States 117 test content: cigarette test, the burnt part does not exceed 80%, the average burning length does not exceed 3 inches, the maximum burning length does not exceed 4 inches, the average burning time does not exceed 4 seconds, and the longest burning The time does not exceed 8 seconds, and the mass loss of open flame combustion does not exceed 4%.
Function: fireproof
Use:soft furniture, mattresses, toys, home textile products
Material: polyester fiber
Three, Comparison of flame retardant products
Product features that can pass the US 16CFR1633 test: flame retardant, anti-melting, a small amount of smoke, no poisonous gas, self-extinguishing effect, can maintain the original state after carbonization, moisture absorption, breathable, hand feeling Soft, elastic and durable, mainly suitable for high-end mattresses exported to the United States.
Product features that have passed the BS5852 test standard: At present, the European market has mandatory flame retardant requirements for soft furniture mattresses and seats. It is mainly suitable for exporting to the European market, and high-end sofas are used more.
The characteristics of products that can pass the TB117 test in the United States have relatively low fire protection requirements among the three, and the longest burning time does not exceed 8 seconds. It is suitable for textiles and furniture exported to the United States.
gram weight: 40g/㎡～2000g/㎡
width: 0.5m～3.2m
thickness: 0.5cm～5cm
Product certification: TB-603, CFR-1633, UL-94.
Characteristics: permanent flame retardant, moisture absorption, breathable, soft to the touch, durable elasticity, good heat insulation. When burning, there is only a small amount of flue gas, which does not dissolve droplets or release poisonous gas. It has a self-extinguishing effect and maintains its original shape after carbonization.
Application range: Mainly used in sofa, mattress, clothing, etc. Name: ca133 flame retardant cotton Applicable objects: sofa seats in public facilities such as seats in hotels, hotels, KTVs and other public places Production principle: polyester fiber wool fiber viscose fiber is formed by carding and laying, and mixed with low melting point fiber made. Product features: white, soft, self-extinguishing and other characteristics in line with the American flame retardant test standards.
Product Features:
Gram Weight: 100g/㎡～500g/㎡
Width: 0.5m～3m
Thickness: 0.5 cm～5cm
Product certification: American CN-117, British BS-5852, ROHS.
Features: good tensile force, good resilience, environmental protection, strong fire resistance, no heavy metal content , Loose quality, soft, comfortable feel, not easy to be deformed by washing, and free.
Criteria: 1. The maximum heat release efficiency cannot exceed 80 kW;
2. The total heat release in the first 10 minutes cannot exceed 25 MJ;
3. The concentration of CO (carbon monoxide) released by the sample should not exceed 1000ppm for more than 5 minutes;
4. The smoke density should not exceed 75%.
Product advantages:
1. Pure white, soft hand feel, excellent elasticity, good moisture absorption and ventilation.
2. Natural flame retardant fiber is used, and there is no dripping phenomenon. It has a permanent self-extinguishing effect
3, and forms a dense carbonized layer during combustion. The content of carbon monoxide and carbon dioxide is low, only a small amount of non-toxic flue gas is produced
4, stable acid and alkali resistance, non-toxic, and does not produce any chemical effects. The product is naturally degradable and environmentally friendly
