3tex × 97.2tex denim by liquid ammonia after finishing the physical and mechanical properties of performance index shrinkage /% breaking strength / N
58tex, 5.83tex Abbott liquid by liquid ammonia after finishing, flexibility and dimensional stability of a greater increase, the appearance of flat Ting, soft to the touch, a strong sense of silk, and if the combination of resin finishing, the product can reach the PP level.
Liquid ammonia finishing machine for a variety of fabric adaptability, such as cotton thick fabric 83.3tex × 97.2tex denim, 58.3tex × 58.3tex yarn card, 41.65tex × 72.88tex sanitary cloth, After the liquid ammonia finishing, the shrinkage rate is greatly reduced, the resilience is greatly improved, feel very soft, shiny soft, such as with the anti-shrink, soft finishing combination, the effect is more ideal.
