Oil repellent waterproof aramid fabric finishing process

Oil repellent waterproof aramid fabric finishing process
Fabric surface rolling, contact angle is 180 degrees, non wetting. The same kind of oil repellent test droplets at the Fang Ping organization on the fabric with weft density increasing, test the droplets to maintain its shape of drop time growth, permeate area after diffusion was also decreased; the law on anti tear organization plaid fabric, but Fang Ping fabric oil repellent effect is remarkable. Now the specific oil repellent test liquid diffusion, the permeate area decreases. Analysis of test results. By the three factor three level orthogonal test of water and oil repellent, water and oil repellent test result, optimization of process each kind of fabrics and finishing 6, by use of analysis of variance, the influence degree of various factors on the fabric water and oil repellent effect. 7. Fang Ping fabric under different experimental schemes water and oil repellent fabric specifications / root - (10cm) - 1 finishing test results A finishing agent G - L - 1B - L - /g crosslinking agent 1C baking time / min water repellent oil repellent grade level that the other stitch fabric finishing process water and oil repellent effect, oil repellent effect level reached 8, the water repellency level to 8, the change of oil repellent finishing process has little effect, has certain influence on the water repellent effect. Anti tearing grid fabric under different experimental schemes water and oil repellent fabric specifications / root - (10cm) - 1 finishing test results A finishing agent L 1B crosslinking agent of /g - L - 1C / min baking time and water repellent oil repellent grade level that the finishing process of anti tearing grid material the water and oil repellent effect, determine the optimal scheme, the main consideration of water repellent effect, when the water repellent effect of the same level, in accordance with the dosage of finishing agent, crosslinking agent, baking time order, select the minimum value as the optimal process for each fabric. 6 each kind of fabric and water repellent finishing and optimization technology of oil finishing effect of fabric structure and fabric specification / root (10cm) - 1 process optimization test results of A finishing dosage / G - L - 1B - L / g crosslinking agent 1C baking time / min water repellent oil repellent fabric Fang Ping grade level 017, the dosage of finishing agent, amount of crosslinking agent and curing time on fabric water and oil repellent effect of fabric structure and fabric specification / root (10cm) - 1 to influence the effect of oil repellent effect affect in the data and analysis results showed that the dosage of finishing agent, amount of crosslinking agent and curing time has little effect the effect of 6 kinds of fabric oil repellent finishing agent, but the amount and the amount of crosslinking agent on anti tear plaid fabric waterrepellent effect has certain effect. 1) the use of polysulfonamide aramid 11 blended Siro yarn and pure cotton woven fabric can reach the limit oxygen index of Flame retardant fabric limit oxygen index requirements. (HPC) finishing agent and HPC - crosslinking agent were used to finish the oil repellent finishing of 6 kinds of fabric. The oil repellent grade of the fabric was 8 grade, and the effect was obvious. (three) orthogonal experimental design of three factors with factor finishing dosage, crosslinking agent dosage, curing time, three factors on Fang Ping fabric water and oil repellent effect is not obvious, but the effect of the dosage of finishing agent and crosslinking agent on the anti tearing grid fabric water repellent effect, small three factors the anti tearing grid fabric oil repellent effect. 5Y3VStkU
