Studies of some basic aspects in easy‐care cotton finishing, II. Influence of urea pad on free formaldehyde and strength of crosslinked cotton

Abstract

The conventional pad‐dry‐cure technique used in easy care cotton finishing with N‐methylol compounds was modified by introducing an extra urea pad. That is, the modified technique involves padding the cotton fabric with an aqueous solution of the finishing agent followed by padding with an aqueous urea solution; drying and curing. Advantages of the modified technique lie in smaller amount of free formaldehyde in the finished fabric as well as higher retaining strength. The magnitude of the reduction in the amount of free formaldehyde and that of the improvement in the retained strength depend upon urea concentration in the extra padding bath as well as upon nature and concentration of the catalyst used.

Effects of variations in washing on the formaldehyde release properties of durable press cottons

“…(8) Aftertreatments such as the application of top softeners, dimensional stabilization, and treatments to decrease formaldehyde release (Gregorian and Namboodri, 1984;Hebeish et al, 1979a;Hendrix and Payet, 1984;Pai, 1982; Reinhardt and Daigle, 1984; Reinhardt and Harper, 1984;Reinhardt et al, 1972; Waddle et al, 1959).…”

Improving the Breaking and Tear Strength of Cotton Fabric Using BTCA and CA Crosslinkers

“…Polymer additives have been used mainly in conventional cotton crosslinking to improve wrinkle properties [11,12], abrasion resistance [13], tear strength [14], as well as to inhibit uneven crosslink distribution during drying of cotton textiles i.e. to inhibit migration [15].…”
