1. Cotton fabric flame retardant finishing
Flame retardant finishing of cotton fabrics developed rapidly, currently the more mature, flame retardants can be basically the durability of flame retardant finishing of cotton for industrial production, generally has the following three methods:
A? Proban / Ammonia process, Proban law firm Wilson first used British industrial production, the traditional method is Proban flame retardant THPC (4-hydroxymethyl ammonium chloride), after dipping curing process, improved is Proban / Ammonia process, process as follows: flame-retardant finishing padding Ammonia drying oxidation water washing drying. China has Beijing Guanghua, Jiangyin dye houses, such as the introduction of foreign Anshan cotton dyeing auxiliaries and equipment for production. It is widely recognized as effective flame-retardant fabric strength reduction is small, the process feel less impact. However, equipment problems limit its promotion.
B? PyrovatexCP finishing process. China has Shanghai Pesticide Factory, Changzhou Institute of Chemical Engineering, Tianjin joint material which, East China University of Technology, Qingdao Institute of Textiles and Apparel and other units to produce the additive. Flame retardant products, better durability, resistant to household washing 50 times or even 200 times or more, feel good, but the strength decreased slightly. Domestic use of such flame retardant manufacturers have two thirty.
Cotton temporary, semi-durable flame retardant finishing?? Blankets, wall covering, fabric sofa and so the number of requests is not very high flame washing, these products do a temporary or semi-durable flame retardant finishing can. The ability of 1 to 15 times with warm water washing, but impatience soaping. There are borax ~ boric acid technology, diammonium phosphate process, phosphorus amine process, dicyandiamide and crafts. The technology used in industrial production of cotton fabric much. Qingdao University, School of Textiles and Apparel SFR-203 is a semi-durable flame retardant.
2. Retardant wool fabric finishing Wool has a high moisture regain and the amount of ammonia, it has a good natural fire retardant, but demand higher standards, there is need for flame retardant finishing. The first is a flame retardant finishing of wool using borax, boric acid impregnation, product decoration for a plane with a cloth. Flame-retardant effect of this method are good, but not washable. After 60 years with THPC treatment, washing is good, but the process complicated, feel rough, losing the character of wool fabrics. International Wool Secretariat study is the use of titanium, zirconium, and hydroxy acid complex of the wool textile finishing, satisfactory flame retardant effect, without affecting the feel of wool, so widely used. There are titanium, zirconium, tungsten and other metal complexing agent. Since the late 80s, there are several units in the domestic research and development of hair with fire retardant and finishing process, with satisfactory results. Tianjin Synthetic Material Research Institute developed the compound WFR-866 series flame retardant, one for the WFR-866F (with fluoride complex as the main component), one for the WFR-866B (to brominated hydroxy acid as the main ingredient ). Yan Li woolen mill in Tianjin, Beijing, woolen mill, Beijing Woolen Mill House fire retardant are used sperm and woolen products. College of Qingdao University, developed textile and apparel wool SFW series flame retardant, and Jining woolen mills, woolen mills to develop pure wool Weifang second fire retardant products, flame retardant to achieve and exceed the level of similar products at home and abroad.
Present, pure wool fabric is mainly used in aircraft cabin fire, international hotels, such as carpets, curtains, Tieqiang materials.
3. Polyester fabric flame retardant finishing
Polyester fabric flame retardant finishing date, no ideal to find a suitable flame retardant. 3 phosphate (2,3 - dibromopropyl) (TDBPP) has some effect on the polyester flame retardant, but carcinogenic effects. Bebel MO U.S. company (Mobilchemco) introduced a Antiblaze19T flame retardant, suitable for 100% polyester fabric, is better, less toxic. China Changzhou Chemical Research Institute made FRC-1 shall be guilty of similar products, Changzhou Knitting Factory, Shanghai Knitting Factory with the production of polyester flame retardant fabrics. In addition to the bromine, antimony compounds, such as finishing agent 10 polybrominated diphenyl ethers, 6 HBCDD, antimony trioxide, antimony pentoxide are all studied in the work of the medium with a binder, the flame retardant bonding agent on the fabric.
