In this paper, silver slit yarns combined with cotton yarns were used to produce weft knits. The purpose of this study was to investigate the physical properties as well as the functional properties of weft knit with silver slit yarns. The six different weft knit fabrics were made from silver slit yarns varying knit structure and fabric density. One cotton weft knit was also knitted to compare the properties. Weft knits made from silver slit yarns were characterized by excellent antibacterial properties, electric magnetic shielding properties, UV-cut properties, anti-static properties, and air permeability. Although there were significant differences in the physical properties of different knit structure and the fabric density, weft knits with silver slit yarns were seen to have better end use properties and ideal for apparel than the cotton weft knits.

The specimens were heat treated at 180℃, 190℃, 200℃, 210℃ and 220℃ to observe the change of the physical properties of the double raschel pile fabric. The density, tensile strength, weight, elongation, dyeing characteristics, fabric surface morphology and cross sectional shape were observed by heat treatment temperature. Compared with untreated samples, weight, density and tensile strength were increased with increasing heat treatment temperature. No increase was observed at 220℃. In the case of elongation, it increased to 190℃ but thereafter it could not be observed. In the case of uprightness of brushed hair, it was observed that the gap between the yarns was narrowed and the density was increased and the straightness of the yarn and pile yarn was improved by widening the heat treatment temperature. As a result, it was observed that the uprightness was remarkably improved and the bulky properties was increased. It was also observed that the increase of the dyeability was observed with increasing the heat treatment temperature.

The main purpose of the study was to investigate relationships between subjective evaluation of comfort/discomfort and tactile sensation. It was also attempted to analyse physical properties of fabric, hence to find physical factors which have effects on wearing- comfort. The results were as follows; 1. Polyester fabric B Type ranked the highest on subjective comfort scale of T-shirts. 2. Scratchiness and flexural rigidity among subjective factors were important on overall comfort sensations of the subjects. 3, In winter, subjective factors, suchas Soratchiness, Heaviness & Flexural Rigidity, were significantly correlated with objective factors of Scratchiness, Thickness & Weight, Stiffness, respectively. 4. In summer, subjective factors such as warmth, Heaviness, Clammy & Cling Tension, Flexural Rigidity, were significantly correlated with objective factors of Thermal Insulation, Thickness & Weight, Cling Tension and stiffness, respertively. 5. Scratchiness, Weight, Stiffness & Thermal Insulation among objective factors were important on overall comfort sensation of the subjects.

This research investigated the physical properties of PET coolness filaments and their knitted fabrics including dyeing characteristics of these knitted fabrics according to the different dyeing time and temperature. The coolness filament(S) with non-circular cross-section and hydrophilic property was spun and another commercialized coolness(A) and regular(R) PET filaments were prepared for comparing coolness and another physical properties. Qmax of coolness knitted fabric made with S filament was higher than that of R-PET filament, and the maximum value of Qmax of S knitted fabric was shown at the dyeing conditions of temperature, $110^{\circ}C$ with 30 min. or 40min. It was shown that hand of S knitted fabric was a little harsh comparing to A and regular knit specimens, but shape retention and wearing performance of garment made with S knit specimen were estimated as good owing to high bending and shear rigidity. K/S of S knitted fabric was higher than those of regular PET and A knit specimens. Dyeing fastness of coolness knitted fabric showed between 4th and 5th grade.

The stretch fabrics were made by the use of PTT[Poly(trimethylene terephthalate)] fibers and changes in their physical properties were analysed. Tenacity and elongation of D-1(PTT DTY) yarn were 3.32 g/d and 50.4%, respectively, while these of D-2(PTT+CDP DTY) yarn were 2.46 g/d and 32.1%, respectively. The tenacity of PTT-1 and PET-1 fabrics was similar, but the elongation of PTT-1 and PET-1 fabrics was 75% and 44%, respectively. Thus, the elongation of PTT-1 fabric was two times higher than those of PET-1 fabric. In addition, the elastic recovery at 20% elongation of PTT-1, PTT-2 and PET-1 fabric was 85.0%, 80.5% and 60.0%, respectively, indicating that so PTT-1 fabric showed better elastic recovery. The light, wash, and abrasion fastness of PTT-1 and PTT-2 fabrics were above Grade 3, Grade 4-5, and Grade 4-5, respectively. Therefore, there was little effect of substance on the fastness.

the change of physical properties (thickness, weight, air permeability) and mechanical properties(abrasion resistance breaking load and displacement) of samples were determined after heat exposure by a RPP tester. The effect of exposure time and heat flux intensity on the changes and the relationship between physical properties and mechanical properties were investigated. FR treated cotton Kevlar/PBI and Nomex with different structureal characteristics were chosen for specimens. The changes of physical properties and mechanical properties were calculated based on their initial values before heat exposure. The longer exposure time and the high heat flux intensity the more changes of those properties. Heat flux intensity was more effective on the changes, The showed to be affected by an interplay of shrinkage and pyrolysis products loss. The changes of thickness and abrasion resistance showed to be higher for plain weave fabric and those of air permeabiliyt and breaking load and displacement for twill weave fabric. While FR treated cotton which have high RPP value experienced serious and detrimental changes after heat exposure Kevlar/PBI which has low RPP value showed no high changes. In conclusion it could be confirmed that when total performance of a protective clothing is estimated retention capability of physical and mechanical properties after heat exposure as well as RPP value must be considered.

In the modern fashion industry, efficiency has been increasing thanks to development of computer graphics, IT technology, and digitalization. Unlike the past when fashion design heavily depended on handwork, digitalization of fashion industry makes fabrication time shorter and enables designers to adopt comprehensive expression, generating high value-added product. The Apparel CAD, an example of the digitalized fashion industry, has been developed from 2D system into a system providing 3D simulation. Digital clothing can be determined as an activity of designers using the tool in order to fabricate pattern and simulate its designed clothes in the virtual space of computer. In this study, physical properties of eight materials, which can be utilized on a par with current fashion trend, have been specified. For more sophisticated investigation, external appearance of the material was investigated by 3D scanning. In order to examine the physical properties of fabric specimens, KES(Kawabata Evaluation System) measurements and other physical property measurements were made. With the results, virtual material and clothes were simulated via CLO 3D, one of 3D apparel CAD systems. Then, virtual fabrics and clothes of similar types were generated and analyzed.

Non-woven fabric is a textile product made by spinning thermoplastic polymers without manufacturing processes such as stretching, doubling, twisting, weaving, and knitting to form a sheet-shaped web in which fibers are tangled with each other, and then combining them by mechanical and physical methods. In addition, the non-woven fabric manufacturing process has various raw material choices, high productivity, so it is a textile manufacturing technology that can have various uses and increase added value. This study was conducted to control the shape and physical properties of products by improving the manufacturing method of melt-blown non-woven fabrics using process technology that easily changes the shape of non-woven fabrics and improves mechanical properties. In particular, it is considered that a non-woven fabric with a thin material shape and improved mechanical properties will be easily applied to a continuous secondary battery manufacturing industry such as roll to roll operation.
