            Development of aramid ecological flame retardant fabric
            
                    Development of aramid ecological Flame retardant fabric
            
The flame retardant PTT staple blended yarn antibacterial and Kevlar developed a ecological Flame retardant fabric, analyzed the key technology of winding, warping, sizing and weaving process, and test the performance of the fabric. The results show that the flame retardant properties of the fabric and has excellent antibacterial effect, wrinkle resistance and anti pilling property is good, can use the field of better development taking flame retardant fabric, promoting the development and application of Home Furnishing flame retardant clothing. With the enhancement of people's self-protection awareness, functional and environment-friendly fabrics are becoming more and more popular with consumers.
            
At present, China's flame retardant textile products from the hotel, hotels and other crowded public places gradually taken to the family popularity, to the development of flame retardant protective fabric has brought a better opportunity. The finishing fabric with flame retardant flame retardant function easy to reduce because washing, better flame retardant aromatic polyamide, polybenzimidazole and other synthetic fiber by taking comfort and not easy to take Home Furnishing, therefore, the development of flame retardant textile fabric has good air permeability, crease resistance and excellent feeling became important study of textile science and technology workers.
            
The inorganic flame retardant nano antimony non toxic and volatile three oxidation two antimony (ATO) and antibacterial activity of environment-friendly nano attapulgite silk is added to the PTT solution, PTT short fiber preparation with flame retardant and antibacterial function, and blended with aramid fiber, developed 14.8texPTT / Fang PSA 50 / 50 blended yarn and functional protective fabrics, and the production process and the key technology of fabric are discussed.
            
1 fabric yarn fabric specifications are used to develop the 14.8texPTT / 50 / 50 polysulfonamide fiber blended yarn, warp density was 475 / 10cm, 278 / 10cm root weft density, the total number of warp 7600, finished width 160cm, with 1 shows grid structure are interwoven into the reed by 4 / reed.
            
The main process of 2 production process of fabric production is: AUTOCONER338 automatic winding machine, warping machine, Japanese gold pill S432 Zook, through the SOMET sizing machine, rapier loom, machine checking, mending and packing.
            
The rigidity of aramid fiber in the winding yarn is relatively large, and the main measures should be taken in order to reduce the generation of regenerated hairiness:
            
1) keep the yarn clean and smooth;
            
2) lower the speed of winding, set to 1150M / min;
            
3) equipped with electronic yarn cleaner and air splicer;
            
4) using metal grooved drum. Electric cleaning parameters: NEP + 250%, + 120% * 1.5cm thick section, long thick section + 20% * 20cm, 20% * 20cm long details. At the same time, the yarn weight should be mastered at lower level to ensure the good forming of the bobbin. The process principle of "middle speed and small tension" is adopted in the 2.2 warping process. In order to keep the tension of the yarn uniform, the method of changing the collective tube and sectional arrangement of the tension is adopted, and the speed is controlled appropriately, which is set at about 650m / min. The number of warping is 844, the whole 5 axis, the 845 axis and the 4 axis. Winding density should not be too large, so as to avoid the loss of elastic yarn breakage and unwinding sizing.
            
2.3 PTT / aramid yarn sizing has the characteristics of high rigidity, high strength, hairiness and long wait, pay attention to sizing coating, reduce hairiness and therefore Afterwaxing yarn enhanced flexibility and abrasion resistance, reduce the probability of warp sizing formula by brittle broken is PVA - 179950kg, TB - 225 modified starch 30kg, KT - 1 polyacrylic acid size 8kg, antistatic agent 1kg, wax 1.5kg. The sizing process is speed 55m / min, the pulp temperature is 92, the slurry concentration is 1.3%, the grouting force is 10kN, the sizing rate is 8.5%, and the moisture regain is 6%. After pulp strength increased by 6%, hairiness reduced by 18%.
            
2.4 weaving using SOMET rapier loom, with clear and open to the normal boot as the premise, the tension is too large to control, in order to reduce yarn hairiness entanglement caused by the opening is not clear, reduce weft warp caused by obstacles. PTT / aramid yarn has a good elongation. In order to reduce weft shrinkage defect, weft and rapier should be used to handle the weft yarn. Weaving process parameters are speed 320r / min, rear beam height 700mm, rapier penetration time 62 degrees, heald time 300 degrees, opening time 310 degrees, opening height 29mm. The weaving process in order to reduce parking rung to strengthen operator skills training, and the two rotation weft weft bobbin. 3 performance test after the test, the performance of flame retardant protective antibacterial fabric 14.8texPTT / aramid 50 / 50 blended yarn for the warp breaking strength is 655N, weft breaking strength is 560N; warp tearing strength is 134N, the zonal tearing strength is 176N; the crease recovery rate was 87% weft, crease recovery rate was 82%; the anti pilling performance for 3.5; the inhibitory rate was 65%; test the damage length of 35mm using vertical burning method. The spinning additives used in the PTT fiber used in the product development are all eco-friendly and non-toxic ecological materials. ATO is an excellent inorganic antimony flame retardant, and attapulgite is also a kind of ecological material
