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.

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.

The dyeing properties of mulberry fiber/cotton blended fabric with Inonotus obliquus are studied through the investigation of the effects of dyeing conditions, such as the concentration of Inonotus obliquus extract colorants, dyeing temperature, time, and pH values on dye uptakes (K/S). In addition, the effects of mordant on the dye uptakes and antibacterial activities are investigated. The results are summarized as follows. The dye uptakes of dyed fabric increased gradually with an increase concentration of Inonotus obliquus extract colorants, the K/S value was the highest when the dyeing temperature was $60^{\circ}C$ for a duration of 60 minutes. As the pH value of the dyeing solution changed to more acidic, the dyeability of the, fabric was improved. The K/S value recorded the highest at pH 3. The antibacterial activities of dyed and unmordanted mulberry fiber/cotton blended fabric showed a high Staphylococcus aureus reduction rate.

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.

In this study, we have compared the relative importance of various washing condition affecting on soil release for P/C blended fabrics. P/C blended fabrics were soiled by the pad-dry method with aqueous and oily soil. The washing procedures of soiled samples were performed by Atlas Launder-Ometer with 27 wash conditions which are combinations of wash temp. wash time and detergent cone. The degree of soil-release was evaluated with CIE 1976 Lab color difference before and after washing. Multiple regression analysis was used to evaluate the optimum wash conditions and the relative importance of the factors providing maximum soilremoval.

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.
