Ester crosslinking of cotton fabric by polymeric carboxylic acids and citric acid
Ester crosslinking of cotton fabric by polymeric carboxylic acids and citric acid. Yang, Charles Q.; Wang, Xilie; Kang, In-Sook (Dep. Textiles, Mechandising and Interiors, Univ. Georgia, Athens, GA 30602, USA). Textile Research Journal, 67(5), 334-342 (English) 1997 Textile Research Institute. CODEN: TRJOA9. ISSN: 0040-5175. DOCUMENT TYPE: Journal CA Section: 40 (Textiles and Fibers) Polycarboxylic acids appear to be the most promising nonformaldehyde durable press finishing agents to replace the traditional N-methylol reagents. 1,2,3,4-Butanetetracarboxylic acid (BTCA) is the most effective crosslinking agent among the acids investigated, but its exceedingly high cost has prevented its use in the textile industry on a com. scale. The effectiveness of two polymers of maleic acid, i.e., the homopolymer (PMA) and the terpolymer (TPMA), are evaluated, along with citric acid (CA) for crosslinking cotton cellulose. PMA, TPMA, and CA have mol. structures similar to BTCA, but are more cost effective. PMA and TPMA are less effective crosslinking agents for cotton than BTCA, probably due to the low mobility of the anhydride intermediate formed by PMA or TPMA to access the cellulosic OH during the curing process. The OH of CA and other a-hydroxyl-polycarboxylic acids hinder the esterification of those acids with cellulose. The IR spectroscopy data indicate that CA esterifies the anhydride intermediates of PMA and TPMA on cotton fabric under curing conditions. Consequently, CA is transformed from a trifunctional acid to a tetrafunctional one with the formation of an ester linkage with PMA or TPMA.

CLASS: IC: C07C055-24; C07C051-42. APPLICATION: JP 83-1784 11 Jan 1983. DOCUMENT TYPE: Patent CA Section: 23 (Aliphatic Compounds) Crude title acid (I), prepd. by metal-catalyzed HNO3 oxidn. of tetrahydrophthalic acid, was washed with aq. HNO3 to reduce the metal residue. Thus, 58% aq. HNO3 contg. 0.6 g NH4VO3 and 1.1 g FeCl3 was treated dropwise with 44% aq. tetrahydrophthalic acid at 60° over 10 h and the mixt. cooled to 10° to give crude I (contg. 2300 ppm Fe), which (100 g) was washed 3 times with 40 g each 68% aq. HNO3 to give 56 g I contg. 8.5 ppm Fe (99.9% pure).
