Silk, polyester, cotton, and wool fabrics were embroidered with varying stitch length of 3mm, 5mm, and 10mm to examine the difference in fabric shrinkage in terms of sewing direction, fabric thickness, cover factor, stitch length, and fiber type. Warp, filling, and bias direction of sewing resulted in no difference in fabric shrinkage. Within the samples with same stitch length, there was less fabric shrinkage in fabrics with higher fabric thickness or higher cover factor. There was larger shrinkage when sewn with longer stitch length. Comparing fabrics with different fiber types but similar fabric thickness, silk and polyester fabrics showed the smallest fabric shrinkage and wool fabrics showed the largest shrinkage. It is shown that similar fabric shrinkage between silk and polyester is due to the similarity in cover factor.

The optimum fabric design plan is recently needed with the relevant fabric shrinkage in dyeing and finishing processes for the various sensible fabrics for garment. For responding this need, the difference of fabric design plan such as fabric density, yarn count and finishing shrinkage has to be surveyed with weaving looms such as water jet, air-jet and rapier looms, and also has to be analysed with weave pattern such as plain, twill and satin according to the fabric manufacturers. Therefore, in this study, 420 polyester weave pattern sheets are collected from 5 fabric manufacturers, and the weave density coefficients of these fabrics are calculated using yarn count, fabric density and 1 repeat weave pattern. These weave density coefficients are analysed according to the fabric manufacturers, weaving looms and various weave patterns. And also the weave density coefficients of 420 polyester fabrics are analysed with finishing shrinkage according to the fabric manufacturers and various weave patterns such as plain, twill and satin fabrics.

This study examined the cause of the phenomenon of shrinkage in machine-embroidered fabrics, specifically those made of thin and pliable fabrics. Four woven fabrics and two knitted fabrics were selected as samples for analysis. The fabrics selected were silk organza, flax linen, polyester chiffon, cotton batiste, polyester raschel mesh, and cotton jersey. The thickness and drapability of the fabrics were observed and the shrinkage of the various types of embroidered fabrics produced using satin & step stitch techniques were measured. Moreover, the correlation between the shrinkage of the machine-embroidered fabrics and the drapability of the original fabrics was analyzed. Also, the colorfastness of six embroidery yarns was determined. The results of the study are as follows: first, the shrinkage of machine-embroidered fabrics increased at a greater rate than in embroidered knitted fabrics as compared to rates in embroidered woven fabrics. Moreover, in terms of stitch techniques, there was a greater shrinkage rate when satin stitch was applied compared to step stitch. Second, the shrinkage rate of machine-embroidered fabrics decreased when a stabilizer was fused onto the fabric. The shrinkage rate also decreased for fabrics when fused with paper stabilizer compared to those without it, and the rate decreased at a greater amount with paper stabilizer as compared to alginate film. Third, since there was a strong correlation between the shrinkage rate of the embroidered fabric and the drapability ratio of the original fabric, it was generally the case that the more pliable the fabric was, the greater the shrinkage rate was when the fabric was embroidered. Fourth, while the embroidery yarns mainly used in machine-embroidery presented an overall excellent level of colorfastness, there was slight color migration of level 4 to level 5 when using viscose rayon.

The purpose of this study is to provide the dyeing and physical characteristics of napped knit fabrics composed of latent crimped yarn. The K/S values, dyeing fastness, thickness, bulkiness, and shrinkage characteristics of three knit fabrics were investigated. The original knit fabric (SK) was composed of 1ply latent crimped yarn (75/36) in the ground and PET DTY (70/100) in the pile loop, in order of napped process the napped knit fabric (SN) was napped SK fabric. In order to compare of latent crimped yarn content, the last knit fabric (DN) was napped 2ply latent crimped yarn were included in the same structure of SK. Dyeability of three knit fabrics was similar but the shrinkage properties of DN fabric were significant different. The bulkiness shows a tendency to increase the bulkiness as increasing the dyeing temperature, and the bulkiness of the SN was higher because of the napping process and optimal content of latent crimped yarn.

Drying processes often cause knitted fabrics to shrink. This study obtains proper drying conditions for in the dryer use that can minimize knitted fabric shrinkage by investigating changes in shrinkage according to drying conditions. The experiment samples were all machine washable plain, mesh, and lacoste knitted fabrics made of 100% cotton. Samples were first washed in a washing machine on a normal cycle. They were then layered on a flat surface in an artificial climate chamber and dried for 24 hours at $20^{\circ}C$ and $40^{\circ}C$, respectively. Shrinkage was measured for 180 minutes at 30 minute intervals after washing. The comparison results of the shrinkage in the washing and drying process indicate that 80.0% and 23.0% shrinkage of plain knitted and lacoste knitted fabrics occurred during the washing process. As the samples dried, the shrinkage of the plain and lacoste knitted fabrics then rapidly increased after approximately 30.0% moisture content. The highest air drying shrinkage occurred over one cycle with insignificant changes in shrinkage after repeated treatments.

Fabrics shrinkage are affected by weaving conditions and are very difficult to be estimated when the amount of fiber consumption and production are calculated. Therefore, we need to standardize fabric shrinkage according to various weaving conditions. To develop the new textile products, we collected and analysed data of fabric shrinkage with the weaving conditions including fabric density and woven structure, tension, and machinery used.

Wool fabric was treated with oxygen low-temperature plasma (LTP) and dichloroisocyanuric acid. The effect of dimensional stability (relaxation shrinkage, hygral expansion, felting shrinkage), tensile strength and elongation, crease recovery, and hand of wool fabric between LTP, DCCA treated wool fabrics and control wool fabric were investigated. SEM photograph showed that a little micro crack was formed on the fiber surface by plasma treatment with hard condition and epicuticle scale was damaged by DCCA treatment. Felting shrinkage, tensile strength and total hand value were much different in each samples.

The objectives of this research were to study the effect of salt-shrinkage finishing of silk on shrinkage degree and dyeing property of cochineal, and to investigate the efficacy of obtained results for imparting surface design effect on silk fabric. Ultimately it was aimed to suggest a technical process for developing natural dyed silk products with diverse design. Premordanted silk fabric was treated with $Ca(NO_3)_2$ solution(gravity: 1.45) at $90^{\circ}C$ for 1 min, washed, dried for further evaluation. The shrinkage of salt-treated fabric was calculated. The effects of salt treatment on the dye uptake of cochineal and colorfastness were investigated. The degrees of shrinkage were 10% and 3% for warp and weft, respectively. The salt treatment resulted in improving dye uptake of cochineal slightly. In addition, it improved colorfastness to washing and light. On the basis of the results, a technical process composed of premordanting, salt treatment and natural dyeing was suggested and using the process, two examples of textile design were presented. It can be concluded to impart various three dimensional surface design effect on silk fabric by applying salt-shrinkage finishing with combination of natural dyeing and mordanting.

The washing efficiency of two types of washing machine- drum(drum washing) and drum using steam jet system(steam drum washing) was studied. The purpose of this paper is to clarify the performance of new steam drum washing. The relationship between washing temperature and washing efficiency(reflectance(%)) by soil removal, and that between washing temperature and electric energy consumption, Fabric damage evaluated by Danish wear method, Fabric shrinkage(%) during laundering were investigated, and compared with those in drum washing machine. Washing efficiency of steam drum washing according to washing temperature is better than that of drum washing. Electric energy consumption and fabric damage in steam drum washing are lower than those of drum washing. Fabric damage increased as washing temperature increased. Shrinkage of fabrics in steam drum washing and drum washing are about same. Therefore, we assumed that in the case of steam drum washing using steam jet system, washing efficiency remarkably increased, and fabric damage decreased, even with a lot of saving in given electric energy and water used.
