The static frictional force between two specimens of the same fabric finished with lubricants has been determined to investigate the effects of lubricants on the surface property of fabrics. Plain weave cotton fabrics were finished with the polydimethylsiloxane (DMPS) with 20, 100 1000 and 10000 cs in viscosity and 0.05, 0.1, 0.5, 1.0, 2.0 and 5.0 wt% in concentration of the finishing solution. The effect has been considered of viscosity and concentration of lubricants on the fabric smoothness.
The static frictional force at the rirst frictional cycle decreased or the smoothness of the cotton fabrics increased with increase of DMPS concentration. It reached the plateau at 0.5 wt% of DMPS concentration. Furthermore the smoothness of the cotton fabric increased with increase of the viscosity of DMPS. The effects of DMPS on the static frictional force during the repeated frictional cycles were also discussed.

Results are reported of the improvement of the sublimation fastness of heat transfer materials by the chelation. Two metal chelate type nonionic dyes with lower polarity are synthesized. The observed sublimation temperature of both dyes are below 170 °C. The heating of the printed paper is done by the laboratory hot press with both upper and lower hot plates maintained at the temperature. The printed papers have been made with hand screen method. After dyes are transferred by the heating from the printed paper to a fabric, the chelation of metal ions is applied by a wet after-treatment. The new dye formed in the fiber is more resistant to sublimation due to the increased molecular weight. Percent retransfer to polyester fibers at 200°C and for 30 minutes in dwell time before and after the chelation are ca. 70% and ca. 7% respectively.
