In this the study, polyester/cotton(P/C) blended fabrics with fine denier were developed to get the light weight compared with the traditional P/C blended fabrics. Moreover, the width of the fabrics was extended by the tenter during the final heat treatment to get the lower fabric density and lighter weight. Then, the physical properties of these fabrics were analysed. The results were as the follows: The developed fabrics had 22.6-31.6% lighter weight than the traditional fabrics with the same fabric width. The weight of fabric decreased drastically with the fabrics width down to 67.1 $g/m^2$. The fabric density for the warp direction decreased with the fabric width. The tenacity and the elongation of the developed fabrics was little lower than that of the traditional fabrics. The air permeability of the developed fabrics increased with that of the traditional fabrics. The stretch rate of the developed fabrics decreased with increasing the fabric width. Residual stretch rate of the developed fabrics was more stable than that of the traditional fabrics. Residual stretch rate of the developed fabrics increased with the fabric width, but the highest value was less than 5% which is quit stable.

In this study the effects of swelling and fixing agent for the cotton side of polyester/cotton blended fabrics and the thermosol temperature on the dyeing properties and fastness. were investigated, when the polyester/cotton blended fabrics were dyed with a disperse dye which was able to dye both side of fiber by one bath one step thermosol process. The obtained results are as follows; The dye adsorption decreased with the increase of cotton blend ratio in polyester/cotton blended fabrics, when the ratio of swelling and fixing agent for cotton side was constant. As the thermosol temperature increased up to $210^{\circ}C$, the dye adsorption were increased, but that effect was less significant when the cotton blend ratio was higher.

This study evaluated the performance of bedding fabrics consisting of warp (150d/144f, polyester) and weft (polyester, Tencel and cotton MVS blended spun yarn) with blend ratio of weft. We measured electrostatic propensity, moisture properties, pilling properties and mechanical properties of the fabrics for this study. F-P fabric showed outstanding moisture properties and pilling properties. However, tensile properties and electrostatic propensity were relatively inferior to other characteristic values. Significant static electricity may make F-P fabric uncomfortable. F-P7C3 fabric showed outstanding moisture properties and pilling properties. Static electricity may make F-P7C3 fabric uncomfortable; in addition, F-P5C5 fabric showed outstanding moisture properties and pilling properties. Rough and stiff hand feel were expected to increase because tensile properties decreased and surface properties increased. F-C fabric showed outstanding pilling properties and electrostatic propensity. However, it showed inferior moisture control properties. F-P5T4C1 fabric showed outstanding moisture properties, pilling properties and electrostatic propensity. Several properties are outstanding; however, the hand feels are very rough and stiff from bending. The water evaporation and static electricity increased with increasing polyester content. As the content of cotton increased, tensile properties were improved. However, water evaporation and static electricity decreased. The addition of Tencel increased the thickness and compression energy so that it exhibited a soft characteristic upon compression and an excellent moisture control properties, but the surface became somewhat coarse.

Influence of the fluorescent whitening agent(FWA)'s adsorption on the whiteness of cotton and on the color change of the dyed fabrics was investigated by repeating wash cycles. Cotton 100% and cotton60/polyester40 blended fabrics were dyed pink, blue and yellow, and cyanuric chloride diamino stilbene(CC/DAS) and distyryl bisphenyl(DSBP) were used for the FWA with laundry detergents. Fabrics were washed at $20^\circ{C}$ with Terg-o-tometer. The FWA adsorption amount was measured by the absorption intensity for the pyridine-water extracted solution. The FWA adsorption increased on the cotton fabric with the wash cycles. Though adsorption of CC/DAS continuously increased up to the 20th cycle, that of DSBP increased sharply before the 10th cycle and reached an equilibrium. The whiteness of the fabrics dried in the shade was greater than that dried under the sunlight through window glass. The color change of dyed fabrics was increased by the number of wash cycles. Pink changed more greatly than blue, yellow or grey cloth. The color change(\Delta{E)}$ of dyed fabric washed repeatedly up to the 20th cycle with the detergent without FWA was less than 1. It is recommended to wash pale colored fabric with the detergent free of FWA.

In this paper, the fabric specimen undergoes repeated laundering under given condition. After this cyclic laundering was applied, the crease recoveries of the specimen were measured using shirley crease revovery tester in order to evaluate the effect of factors at given condition during crease deformation. 5 samples of grey plain cloth were desized, alkali-scoured, bleached, whased with water, and air-dried. All tests were made on samples preconditioned to $65\%\;RH\;and\;20^{\circ}C$. The experimental results were analysed statistically to relate crease recoveries and the properties of smaples, recovery periods (time) of crease. Furthermore, the crease recoveries of core-spun yarn woven fabrics were discussed in comparison with those values for $100\%$ combed cotton yarn woven fabric and $65\%$ polyester $35\%$ carded cotton blended yarn woven fabric. The results obtained are as follows; 1. Regardless of materials, remarkable decrease are observed in crease recoveries about 1-5 cycles of the repeated laundering, but slack decrease are observed in crease recoveries after 5 cycle of the re-peated laundering. 2. Crease recoveries ($\alpha$) of core-spun yarn woven fabrics are relate to recovery periods (t) of crease as follows; log$\alpha$=0.01415 log t+2.1168 ($r^2=0.94$) 3. Core-spun yarn woven fabrics were superior to $100\%$ combed cotton yarn woven fabrics and $65\%$ polyester $35\%$ carded cotton blended yarn woven fabric in crease recoveries. 4. Crease recoveries ($\alpha$) of core-spun yarn woven fabrics are relate to cover factor (CF), thickness (T) at pressure 0.5 $gf/cm^2$, weight (W) as follows; log$\alpha$=-0.3482 log CF-0.4924 log T-0.4727 W+2.4243 ($r^2=0.88$) 5. Crease recoveries ($\alpha$) of core-spun yarn woven fabrics are relate to 2HB/B, 2HB/W, $\sqrt[3]{B/W}$, WC/T which are concerning to formation of weared clothes and bending Iran formation behavior as follows: log $\alpha$=0.0091 2HB/B+0.4667 2HB/W+0.0185 $\sqrt[3]{B/W}$+0.0114 WC/T+1.8433 ($r^2=0.86$)

In this study, for different test methods of the performance of sewing threads were used to evaluate the sewability of 10 different industrial threads. Sewability evaluations related to the breakage of thread during sewing operation were investigated by seam length and fabric thickness method (Test 1), thread tension method (Test 2), strength retention method (Test 3), and backward sewing method(Test 4), and discussed. Two of the methods, Test 1 and Test 2, simulated very harsh sewing conditions which each thread could accept as an evaluation of its sewability. Core spun thread ranked with the best sewability generally and followed by air jet textured (ATY) thread. Spun thread was superior to the filament thread in sewing thread type. In general, there was a high degree of correlation in the results of Test 1 and Test 2. The order of sewing thread by sewability test 1 was polyester spun thread, cotton thread, and p/c core spun thread. The order of sewing thread by test 2 was polyester spun thread, and p/c core spun thread. Cotton threads and cotton blended threads performed better in Test 3, and ATY threads and core spun threads in Test 4.
