In this study, we investigated the clean appearance and good stretch properties. Usually, clean appearance concerned with the dyeing properties of core and effect yarns. The dyeing properties between core yarn (conjugate yarn) and effect yarn were determined by the build-up and the color differences using the four different yarns of SDY FD(spindraw yarn full dull), SDY CD(spindraw yarn cation dyeable), POY FD( partially-oriented yarn full dull) and POY CD(partially-oriented yarn cation dyeable). We used the single color dye of C. I. Disperse Blue 79 and mixed colors made by C. I. Disperse Red 60, C. I. Disperse Blue 56, and C. I. Disperse Yellow 54.

This research has a main focus on providing fundamental data for on-the-spot industrial fields by comparing and contrasting physical properties of fluffy spun-like material. The fluffy spun-like yarn is developed as fluffy yarn similar to natural spun-like yarn by treating polyester(FDY and + type shaped DTY) with ATY machine. In this experiment, using ATY machine for raw material texturing, we produced two fluffy yarns: (i) + type shaped(50d/36f, DTY) as core yarn and 100d/192f FDY as effect yarn[ATY(D)], (ii) FDY(75/36) as core yarn and 100d/192f FDY [ATY(F)] as effect yarn. After producing thous yarns, we twisted them with 500T/M, 700T/M, 1000T/M, respectively. produced yarns through this process were used as the samples for this experiment. Even though the shrinkage of fluffy yarn ATY(F) and ATY(D) becomes high as treated temperature rises and treated time lengthens, it is more affected by treated temperature then by treated time. In this experiment, produced fluffy yarn[ATY(D)] shows a little high values for temperature, but almost same values for higher temperatures. When we compare ATY(F) with ATY(D) fluffy yarn shows more natural fluffy yarn surface structure like natural cotton. The shrinkage of 700T/M twisted ATY(D) fluffy yarn show about 11% under treated temperature $180^{\circ}C$ and treated time 30min, and about 7% under $120^{\circ}C$ and 30min, respectively. But the shrinkage of 1000T/M fluffy yarn shoes about 9% and 6% under same conditions. Regarding treated time, tenacity and initial modulus of ATY(D) fluffy yarn rise high until 30min, but do not show much increase above 30min. Regarding treated temperature, tenacity and initial modulus of it rise high aboyer $140^{\circ}C$.

Needle contamination was investigated using a test rig simulated the knitting points in the knitting machine in relation with the characteristics of knitting yarn such as yarn type and moisture contents. When used open-end yarn compared with combed and carded ring-spun yarns, the needle contamination was significantly increased because of the higher friction between yarn and needle by the fly and other impurities. Also Lower moisture content of the yarns aggravated the needle contamination. In addition knitting yarn breakage was substantially influenced by the higher needle contamination.

건축용 막재는 일반적으로 직포와 코팅으로 구성되며, PTFE 계열 막재는 유리섬유로 만들어진 직포에 테프론 코팅으로 구성된다. 일반적으로 PTFE 막재에 사용되는 직포에는 $\beta$-yarn이 주로 사용되며, $\beta$-yarn이 아닌 $\alpha$-yarn이 사용된 막재도 점차적으로 사용되는 시점이다. 그러나 $\alpha$-yarn으로 직조된 직포로 만들어진 건축용 막재의 특성에 관한 정보는 일반 막재에 비해 많이 부족한 편이다. 따라서 건축용 막재를 구성하는 직포를 만드는 원사의 굵기에 따른 막재의 역학적 특성에 대한 연구가 필요하다. 본 연구에서는 실험을 통하여 원사가 서로 다른 막재의 인장 특성을 비교 분석하고자 한다.

In order to examine the changes in the appearance properties and the post-adhesion appearance properties of Hanji yarn blended fabrics : 100% Hanji yarn fabric, two kinds of cotton / Hanji yarn blended fabrics and 100% cotton fabric, were selected and fused with three kinds of interlinings. After fusing, changes of standardized KES values were examined. 1. W/T, B/W of Hanji yarn blended fabrics was higher than that cotton fabric. WC/W, 2HB/W, 2HB/B, and 2HG/G values of Hanji yarn blended fabrics are lower than cotton fabric. This means that the Hanji yarn was mixed, shape retention, wrinkle recovery was improved, and the drape property was lowered. 2. After fusing, W/T, shape retention, wrinkle recovery of Hanji yarn blended fabrics increased, and WC/W values of Hanji yarn blended fabrics decreased. The wrinkle recovery property of Hanji yarn blended fabrics were improved; however, the 2HG/G value of Hanji yarn fabric increased due to fusing, and the wrinkle recovery property of Hanji yarn fabric decreased. 3. In the selection of adhesive core, I1 adhesive core is excellent in terms of shape stability and wrinkle recovery; however, an I3 adhesive core is recommended for drape and silhouette formation. When the fabric of the adhesive core was PET, it was found to penetrate better between the fabrics during adhesion than the case of cotton fabrics.

This study surveys the fiber behavior in yarn formation and the Physical properties of Solo-spun yarn. The specimens were made by six types of Solo-spun rollers with fixed twist multiplier In the previous part, the physical properties such as yarn count, evenness, strength, and breaking elongation of these yarns were compared with the properties of ring spun yarns and analysed with the mechanism of Solo-spun yarn formation. In the second part of this report, the abrasion resistance and hairiness were discussed with respect to the micro yarn structures. The narrower the groove width of Solo-spun roller is, the more active the bulk fiber migration is. The Solo-spun yarn structure has two groups. One is shorter than the other one in longitudinal direction of yarn and has the same structure as ring-spun yarn, which is derived from the smooth zone on the surface of Solo-spun roller. The other one is longer than the former and there are the wrapping fibers. This part is derived from the conflicted grooves on the surface of Solo-spun roller.

This study investigates the physical properties of Murata Vortex Spinning (MVS) blended yarn with yarn count(20's, 30's, 40's) and blend ratio(Polyester 100, Polyester70:Cotton30, Polyester50:Cotton50, Polyester30:Cotton70, and Polyester50:Tencel40:Cotton10). This study evaluated tenacity, elongation, bending rigidity, bending hysteresis, hairiness coefficient, irregularity and twist number. The structure of MVS blended yarn influenced stress, strain, bending rigidity, bending hysteresis and the hairiness coefficient of MVS blended yarn decreased as the yarn count increased. MVS blended yarn consists of core and sheath. The core of MVS blended yarn is composed of a parallel fiber with a wrapping fiber that covers thecore fiber. This special structure of the MVS blended yarn effects the physical properties of the yarn; in addition, the mechanical properties of the component fibers influenced the stress, strain, bending rigidity, bending hysteresis and hairiness coefficient of MVS blended yarn with the blend ratio. Polyester decreases and cotton increases resulted in decreased physical properties. A similar polyester content increased the tencel and physical properties. Appropriate physical properties and a variety of touch expression can be realized through a correct blend ratio.
