“…Considering this and also the fact that a small number of tests were done, the difference seems to be insignificant. Similar results have also been reported for cotton fabrics [4]. Table III it is seen that when a jute carpetbacking cloth is tufted, there is substantial loss in strength across the direction of tufting.…”

“…Interest in liquid ammonia as a swelling agent for mercerization of cotton yarns and fabrics [1,[3][4][5]8] has increased recently because of its inherent advantages over caustic soda, such as ease and rapidity of wetting, ease of removal of the reagent, reduced stream pollution, and lower cost due to recovery of the reagent. A few patents have made the method commercially viable [2, 9J.…”

“….. At the 1968 conference referred to above, our contract researchers reported results [8] indicating that liquid-ammonia treatment, though superficially resembling caustic soda mercerization, may have some advantages over the latter as a pretreatment for crosslinking. For example, the liquid-ammonia treatment itself contributed significantly to the DP rating.…”

“…The variation in the amount of formaldehyde extracted in the Japanese Law 112-1973 test with the pH of the extracting medium [8] suggests that the stability.of a finish in this test depends on hydrolysis resistance. Also, formaldehyde is released from odorfree, fully-cured, washed fabrics in the AATCC Sealed-Jar Test [16], an accelerated test originally developed for the prediction of odor in stored sensitized fabrics [14].…”

Commercially practicable preparation and finishing techniques have been studied that can be combined to produce improved durable-press or easy-care woven cotton fabrics, especially lightweights. Fabric mercerization combined with extensive stretching in the filling direction was highly effective in improving tensile and tear strength after subsequent finishing, especially in the filling direction.As an alternative to mercerization, liquid-ammonia treatment on commercial equipment had the additional benefits of greater fabric softness, better abrasion resistance, and better fabric appearance after laundering. Finishing with so-called buffered glyoxal crosslinking resins gave a consistently better balance of durable-press rating to strength than the older, less-buffered ones. Application of finish with a low wet pick-up technique resulted in better chemical efficiency and abrasion resistance than a conventional pad application.

The effect of liquid ammonia on cotton fabric was studied using x‐ray diffraction (XRD) and electron microscopy. A phase diagram is presented describing the relationship between disordered cellulose, cellulose I, and cellulose III. The transition from cellulose I to III proceeds through the liquid ammonia. Cellulose III is obtained upon drying the ammonia‐cellulose without the presence of water. Treatment of the cellulose III or of the ammonia‐cellulose with water brings about the formation of cellulose I. The degree of crystalline order achieved in water is enhanced by heating, which is consistent with a glass transition temperature between room temperature and 100°C. The cellulose III crystallites obtained are much smaller than those of cellulose I,16‐23Åas against 50‐80Å The interaction of ammonia with cotton cellulose is faster than with other swelling agents, such as ethylamine. The penetration of ammonia into the secondary wall of the cotton fiber is not only along the concentrical rings, as is the case with water, but also radially across the rings. Prolonged soaking in water increases the crystallite size with simultaneous rejection of swelling water.
