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.

The aim of this study is to contribute design development and eco-friendly functional hanji products by imparting pattern and functionality using chitosan and natural colorants. Screen printing was used to produce pattern on pre-mordanted hanji paper followed by dyeing with madder colorants. Printing with chitosan resulted in improving lightfastness as well as pattern formation on hanji paper and in addition antimicrobial activity was imparted. Samples with chitosan pattern after pre-mordanting with Al and Cu showed clear pattern line because of the large color difference between ground and pattern. It was considered that the experimental process studied in this study can be applied to develop various pattern and color effect on hanji products with eco-friendliness and functionality.
