“…The authors of [ 10 ] suggest the use of laser treatment for plain weave woolen fabrics to avoid high fulling shrinkage instead of usual methods of shrinkage reducing. To make these fabrics shrink-resistant, different types of finishing, such as oxidative, enzymatic using different chemical means (keratinase and papain [ 17 ], protease [ 7 ], dicyandiamide, glycolic acid, alkali, hydrogen peroxide [ 8 , 14 , 15 ], Chlorine-Hercosett [ 12 , 13 ], laccase-assisted grafting of poly(tyrosine) [ 18 ], POSS ® nanomaterial [ 19 ], chitosan, wheat starch, and gum Arabic [ 9 , 20 ]), radiation, polymeric coatings, sol–gel coatings, plasma, and laser [ 10 ] treatments, softening, water-repellent finishing [ 21 ], and antimicrobial finishing [ 21 , 22 ], can be customized [ 6 ].…”

“…One of the most important properties of fabrics during different finishing processes is fabric shrinkage in the directions of the warp and weft. For example, woolen fabrics extensively shrink during laundering [ 6 , 7 , 8 , 9 ], felting [ 8 , 10 ], tumble drying [ 8 , 11 , 12 , 13 ], whitening, biopolishing [ 8 , 14 ], and low-temperature dying with acid dyes [ 15 ]. Such laundering parameters as the liquor ratio, detergent concentration, pH, temperature, and time of treatment influence the shrinkage of woolen fabrics [ 16 ].…”

The aim of this article was to compare the shrinkage and air permeability properties of woolen fabrics and fabrics with regenerated wool woven with different weaves for establishing the suitability of regenerated wool for blankets. Two series of products with yarns of different raw materials were woven. One group of fabrics was woven with regenerated woolen yarn in the weft and woolen yarn in the warp. The other group of fabrics was woven only from 100% woolen yarns. The shrinkage in the directions of the warp and the weft and the air permeability of the fabrics with regenerated wool and 100% woolen fabrics with different weaves were investigated. The shrinkage in the directions of the warp and the weft in the fabrics with regenerated wool in the weft and 100% woolen fabrics depended on the float length in the weave. When the length of the weave increased, the shrinkage also increased. The air permeability value changed depending on the number of intersections and the float length. The fabrics with regenerated wool in the direction of the weft had higher air permeability. The Two-way analysis of variance (ANOVA) results showed that the weave influenced the shrinkage in the directions of the weft and warp, but the raw material had no influence on the shrinkage. The weave did not influence the air permeability, in contrast to the raw material. The shrinkage in the directions of the warp and weft and the air permeability did not depend on the interrelationships of the weave group and the raw material of the fabric.

“…33 During the drying process, felting shrinkage of wool fabric is influenced by the moisture content of the fabric, temperature of the fabric, and mechanical action being applied on the fabric. 34 Under different rotation speeds of the drum in the tumble dryer, felting shrinkage is greatly depending on mechanical action. As shown in Figure 7, shrinkage of untreated wool fabric changed with the rotation speed of the drum.…”

Tumble dryers are widely used for drying garments, but felting shrinkage can be caused to wool garments during the tumble drying process. To dry wool fabrics or garments in tumble dryers, the flat dry function has been introduced in the dryers; however, the energy efficiency is very low. The current study investigated fabric movement at different rotation speeds in the tumble dryer and their resultant performances in terms of specific moisture extraction rate, evenness of drying, fabric shrinkage, and fabric smoothness. For shrink-resist-treated wool fabrics, tumble drying at the rotation speed to keep fabric movement in projectile motion accompanied with occasional tumbling could achieve better energy efficiency, drying uniformity, and fabric smoothness. For untreated wool fabrics, introducing vertical movement to the flat dry in the tumble dryer can improve the heat exchange between the fabric and hot air, resulting in an increase in energy efficiency of approximately 30% compared with motionless flat drying. Wool fabric shrinkage can be controlled at less than 2% with the smooth appearance of fabric at grade 3.5 after drying under the recommended drying condition. This study could help tumble dryer manufacturers design optimal drying methods for wool fabrics with the potential for the reduction of energy consumption.

“…The capacity of fabric shrinking during washing also depends on specific washing conditions, such as water solidity, the choice of washing powder, temperature, and the mechanical effect [23,24]. One study [25] analyzed the shrinkage behaviors of untreated wool fabric and chlorine-Hercosett-treated wool fabric with different moisture contents.…”

Analysis of Color Fastness and Shrinkage of Dyed and Printed Linen/Silk Fabrics

et al. 2022

In this study, we analyzed the impact of the dyeing and the digital printing processes of linen/silk fabric (70% linen/30% silk) on its color fastness and shrinkage in the directions of warp and weft. This is a highly relevant topic because a single fabric combines two natural fibers of different origins—silk, a protein, is animal-based, whereas linen is derived from cellulose and is, thus, plant-based. Therefore, the different natures of the two fibers determine distinctive chemical properties. As a result, selecting the optimal technological course of processing for blended yarn fabrics and their yarn is a challenging task. The quality of the conducted finishing is determined by the physical properties of fabrics, such as color fastness to perspiration; soap; dry friction and wet friction; the pH of the fabric after finishing; and the shrinkage of the fabric in the directions of warp and weft. Here, color fastness was assigned the top grade with respect to all potentially harmful factors, except for wet friction. The evaluation proves that the technological regimes employed for digital printing and dyeing in the production item’s fabrics were properly selected.
