Application of Mixtures of Resin Finishing to Achieve Some Physical Properties on Interlining Cotton

To produce interlining fabric, various kinds of chemicals such as cross-linking, softening, stiffening and water repellent agents have been employed. In this work, a mixture of dimethylol dihydroxy ethylene urea (DMDHEU), polyvinyl acetate (PVAc) and some other resins were examined in special finishing of cotton for producing interlining cotton fabrics properties. Majority of cross-linking agents used today is DMDHEU based with low formaldehyde level. In order to elucidate the role of DMDHEU and PVAc in this specific finishing, some physical properties of fabric such as bending length, crease recovery angle, wettability time and thickness were studied with varying their concentrations. Both bending length, thickness and wettability time of cotton fabrics increased on increasing PVAc and DMDHEU concentrations. But, crease recovery angle decreased on increasing PVAc concentration and on the contrary increasing DMDHEU concentration improved the crease recovery angle.
