Abstract
Crosslinking reaction between DMDHEU and hydroxyl group of cellulose on cotton and polyester/cotton fabrics was carried out by the pad4ry-cure(PDC) method in the presence of acidic catalyst. Finished samples were evaluated for durable press(DP) and performance properties. Such analysis was done to investigate distribution of resin. Mechanical properties of fabrics were measured by the KES-FB System and the hand values were calculated from the data of mechanical properties. Effects of add-on(%) on the mechanical properties and the hand were compared. With the increase of add-on, DP rating and WRA increased until they reached over definite concentration and then decreased. Tear strength decreased and stiffiness increased. As add-on increased tensile properties, LT, n, and RT increased. Bending properties, B and 2HB, exhibited the tendency to increase and particularly in the P/C(65/35) blend fabrics, 2HB showed an increase to a great extent. The shearing properties, 6, 2HG, and 2HGS, increased and compression properties, LC, WC, and RC decreased. The surface properties, MIU, MMD and SUD, decreased. With the increase of add-on, stiwness, nispness and anti-drape stiwness increased and fullness & softness decreased.
