Durable Press Performance and Reagent Distribution from Foam Application of DMDHEU

Abstract

Textile properties of a special 30 × 30 Osnaburg-type fabric treated by foam ap plication of DMDHEU were studied in relation to durable press (DP) appearance rating and distribution of reagent residues in fabric samples. The foam treated fabrics were compared to a high uniformity DP fabric and to a DP fabric from conventional laboratory scale, pad-rapid-dry-cure treatment. The products from foam application of DMDHEU were generated under two sets of conditions designed to minimize migration and realize high uniformity of wicking and spreading of reagent liquor into fabric, and to realize near maximum economy in energy by minimization of wet pickup. Fabric performance, the distribution of reagent residues in the fabric, and, primarily, the interrelationship between distribution of reagent residues in fabric and fabric performance are considered and discussed in detail.
