Cotton flame retardant fabric , Thin cotton Flame-retardant fabric has always been a production problem in terms of strength control. How to use it in the current economic downturn? In order to break through the bottleneck of powerful products, reduce production costs and improve product quality, we have done a lot of research and experiments. And recently, it successfully produced a batch of pure cotton, high-strength, light and flame-retardant fabrics exported to the United States. Fabric specification 60X60-20S/1X20S/1, weight 150g/㎡.
Cotton flame retardant fabric , Generally speaking, the thinner the fabric, the more difficult it is to reach the strength standard after flame retardant finishing. According to the first-class cotton printing and dyeing cloth GB/T411 -2008 test method (using GB/T3923.1-1997.5.CM strip method, MICRO-350 CRE tester). Fabric 150-200g/㎡, warp strength 400N, weft strength 220N; fabric 100-150g/㎡, the warp strength is 300N, the weft strength is 180N. Due to the customer’s requirement, the weight specification is 150g /㎡, is at the critical point of strong crossover. For this reason, we adjust the following process formula to make the finished fabric meet the requirements.
1. Use strong protection and environmentally friendly flame retardants. Although the flame retardants currently used in the market are relatively low in price, they have a large loss of strength and contain toxic ingredients such as formaldehyde. Therefore, we do not advocate the use. We generally use more cost-effective and environmentally friendly strong protection flame retardants. The strength loss of ordinary flame retardants is about 50%, while the loss of environmentally friendly strong protection flame retardants is only 10-15%. % and does not contain harmful substances such as formaldehyde.
2. Using long-staple cotton raw materials and ring spinning technology. According to actual comparisons, long-staple cotton ring-spun yarn is 30% stronger than yarn spun from ordinary craft materials. At the same time, due to the reduction of breakages in the production process, production efficiency is generally improved and losses are reduced.
Cotton flame retardant fabric , achieving high environmental protection is not the ultimate goal. It is the general trend to seize the market’s increasing requirements for cost performance and consider the development of new products comprehensively. A little change is a big progress. There is no end to technological innovation and it requires unremitting efforts.
