Flame-retardant cloth introduces the flame-retardant cloth in detail. We generally say that the flame-retardant cloth is not burning in everyone's impression. Actually, it is not right. The fire-retardant cloth actually has a fire when it is on fire, but it can be specified after leaving the flame. Extinguish in time. There are corresponding flame retardant standards, such as: EN470-1, EN531, EN532, NFPA2112, NF
Flame retardant cloth
PA70E and so on.
Classification Flame-retardant cloth fiber-fiber flame retardant and finishing flame retardant are two kinds:
Fiber flame retardant is a high-sun heat-retardant cloth, which is called YSETEX chameleon flame-retardant cloth, which is represented by Shanghai Dongwang's Qingluon and DuPont's aramid. It is darkened after glare or sun exposure and placed for 12 hours. After returning to the original color.
After using the chameleon flame retardant fabric, YSETEX chameleon flame retardant fabric is used.
YSETEX Chameleon Flame Retardant Fabric is placed for 12 hours after YSETEX Chameleon Flame Retardant Fabric is placed for 12 hours. Achieving the Way Due to the cost of fiber flame retardant and finishing flame retardant, there are more flame retardants in domestic finishing.
The two main ways in which textiles achieve flame retardant functionality:
1. The flame retardant is applied to the surface of the fabric or penetrated into the interior of the fabric by a finishing method. These two routes give the fabric a different flame retardant link, and the effects are also different. At present, the best way is to modify the textiles with nano-materials and nano-technology. The cost is low and the effect is continuous. The softness and feel of the textiles have not changed at all, reaching the international first-class level.
2. The flame retardant with flame retardant function is added to the fiber through polymer polymerization, blending, copolymerization, composite spinning, bonding technology modification, etc., so that the fiber has flame retardancy.
In general, fiber flame retardant can make full use of flame retardant than fabric flame retardant, and its effect is more durable and softer. However, in practical applications, a plurality of flame retardants are often used, and the flame retardant effect is achieved by synergistic effects in two or more ways.
The application of flame-retardant wall coverings Beautiful wallpapers and wall coverings have become the new favorite of homes and hotels, hotels, karaoke bars and other interior decoration since 2013. But they have a fatal flaw - not flame retardant, once the fire, it will "fire on the fire." A new nano-grade wall covering, which was recently certified by the Ministry of Housing and Urban-Rural Development, solved this problem. The expert committee believes that this nano-scale wall covering not only has good flame retardancy, but also has many functions such as antibacterial, anti-mildew and heat insulation. Its integration technology has reached the international advanced level and is an ideal decorative substitute.
This kind of wall covering with many colors and feels is completed by Jiangsu Changtai Nanomaterials Co., Ltd., Changzhou Longbei Chemical New Material Co., Ltd. and the Institute of Physics and Chemistry of Chinese Academy of Sciences. According to the main inventor Dr. Wu Jinlong, the main materials of the “Dulaide†wall covering are pure cotton cloth and pure cotton printing decoration, which are functionalized by nanotechnology. The test results of the National Textile Quality Supervision and Inspection Center and the National Building Materials Testing Center indicate that the “Dulaide†wall cloth has the functions of flame retardant, antibacterial, anti-mildew, sound insulation and heat insulation that cannot be achieved by ordinary wall coverings. Waterproof, oil proof, antifouling, its formaldehyde content is less than 1/10 of ordinary products.
According to experts, in developed countries, flame retardant has become an essential function of interior decoration materials. In order to avoid more fire accidents, the Fire Department of the Ministry of Public Security of China has also made explicit provisions. From July 1, 2008, fire-retardant products must be used in public places, otherwise the acceptance will not be passed. ?
Application of Flame Retardant Curtains Curtains are made of fabrics treated with nanomaterials and nanotechnology to achieve flame retardant effects, while also having the following characteristics:
a. Safe and tasteless, environmentally friendly, energy-saving and low-carbon, no washing, no maintenance, always clean, water-saving, and worry-free.
b. The width of the curtain fabric ranges from 1.5 meters to 3.1 meters, which can meet the needs of the height and width of various types of windows;
c. On the basis of the basic functions of the existing curtains, the functions of flame retardant, heat insulation, heat preservation, sound absorption, sound insulation, antibacterial, mildewproof, waterproof, oilproof, antifouling, dustproof and antistatic are added and enhanced;
Market Defects In fact, in the current domestic situation, before the more effective and long-lasting flame retardant is discussed, it is necessary to solve the popularization of flame retardant materials in public places and certain specific occasions.
In the past few years, many people have called on the state to introduce relevant regulations, stipulating the use of flame retardant materials in public places to prevent the fire from threatening people's lives and property. In the past two years, relevant national laws and regulations have been introduced one after another, but the implementation effect has been greatly reduced. The fire at Shanghai Jiaodong Road is still fresh in memory, and the fire in Qinghai Textile Department Store has started again. In the case of the CCTV “3·15†party broadcast in 2011, the construction workers were hot-welded on the building, and the scene of the fire splashing from time to time was thrilling because of the building facades that should have been made of flame retardant materials. The insulation layer, all of which use flammable materials, poses a fire hazard at any time. Construction workers frankly said: "I have become accustomed to such an operating environment." In the subsequent unannounced visits, TV reporters found that the entire market could not find building insulation materials that can be flame retardant. It can be judged that such cases exist in the streets and alleys of the country.
Some people believe that one of the main reasons for the lack of popularity of flame retardant fibers and textiles is the price factor. The price of flame retardant fiber is about 40% higher than that of ordinary fiber. Some hotels and entertainment places are reluctant to buy and use flame retardant fabrics in order to reduce costs, and even use flame retardant to temporarily spray on curtains to cope with safety inspections. . Therefore, in general, the lack of supervision and the low cost of illegal fouls are the crux of the problem. Since there are already corresponding mandatory laws and regulations promulgated, the relevant units are still able to navigate from the middle, and having the option of using or not using them is ridiculous.
In 2011, the US Consumer Product Safety Commission (CPSC) passed a new directive. From January 26, 2011, importers or US manufacturers must provide a flame quality standard (GCCS) for some products, including ethylene. Plastic film, carpets and mats, as well as non-children's clothing textiles. Failure to provide a certificate of conformity or the publication of a false certificate of competency may result in civil penalties of up to $100,000 and may even result in criminal penalties and property confiscation. This should certainly attract the attention of enterprises that export related products, but it is more worthy of the Chinese people to ponder. After all, the life of the Chinese people is also life, and the property of the Chinese people is also property.
In some places, every effort is made to avoid the use of flame retardant materials, and while trying to cope with various inspections, the manufacturers of flame retardant products are struggling to open the market for the products. Since domestic disdain for flame retardant products, then cooperate with foreign countries. Therefore, many companies choose foreign trade, and the amount of flame retardant products they produce for export is much larger than domestic sales. As a result, flame-retardant baby clothing, flame-retardant cushions and other products that appear to be "advanced" in the country have been transported to foreign countries.
However, even if it meets the high standards and high requirements of foreign countries, it cannot dispel the doubts about the quality of products in the hearts of Chinese people. Some domestic customers are very keen to buy domestic flame retardant products, but there is basically no reassurance. It can be seen that the industrial chain and supply chain of domestic flame retardant products are still very imperfect. The mutual suspicion between producers and users, coupled with loopholes in regulatory supervision, has made the popularity of flame retardant cloths repeatedly blocked.
