Compared with prior art, the invention has the advantages that staple fabric after the Liquid Ammonia Treatment have soft, smooth, do not damage brute force, need not press, characteristics that washing shrinkage is little.Although the expanded effect of caustic soda is than liquefied ammonia Senior Three doubly, caustic soda viscosity height, permeate inhomogeneous, owing to liquefied ammonia has good impregnability, thus different with caustic soda mercerising treatment effect, after Liquid Ammonia Treatment, cotton fiber generation swelling, its warp-wise, broadwise are all very even.Liquid ammonia finishing has the meaning of mercerising, but different and traditional mercerising, and it can make staple fabric strength, elasticity and feel increase, and has improved dimensionally stable, and show no sign of that the caustic soda mercerising brought fiber melted erosion and inhomogeneities.
Select two kinds of specification cotton wire union cloths, one is plain weave: CF60*SK42D 180*86, two is plain weave: CF60/1*SK42D 180*100
Adopt following two kinds of technologies arrangement respectively, compare, the results are shown in following table:
Technology one: singe → destarch → liquefied ammonia → typing → preshrunk
Technology two: singe → destarch → typing → preshrunk
The method of testing of above brute force and outward appearance is ISO.1. by liquid ammonia finishing, the bafta brute force is apparently higher than common arrangement; And outward appearance is higher 0.5 grade than common arrangement.2. by liquid ammonia finishing, soft, the high resilience of bafta is significantly better than common arrangement.
