Abstract Modification of cotton with 3-chloro-2-hydroxypropyltrimethylammonium chloride (CHPTAC) has been studied extensively and can be operated by means of exhaustion, cold pad-batch, and continuous and pad-steam methods. Most of the research addresses the cationization of cotton fabric after bleaching or mercerization, or during the mercerization process. In our studies, we performed a comparison of the cationization effects on raw, enzymatic, and alkali-scoured cotton knitted fabrics applying CHPTAC according to the exhaustion method. The charge density of the cotton surface was measured using a Muetek Particle Charge Detector and a “back titration” method with polyelectrolytes. These results were compared with the nitrogen content in the samples, K/S measurements of tested samples after dyeing with anionic dye (Acid Yellow 194), and other physicochemical parameters such as weight loss, whiteness, and wettability.

Knitted fabrics are the preferred structures in athletic wear in which demand for comfort is a key requirement. Heat and liquid sweat generation during athletic & exercise activities must be transported out and dissipated to the atmosphere. A key property influencing such behaviors is porosity. Two parameters that characterize it are pore size and pore volume. One of the objectives in this research was to come up with models that can predict inter yarn pore size and pore volume for simple weft knitted structures, from fabric particulars, such as courses and Wales, count, yarn size, stitch density, thickness and other geometrical details of the fabric, which characterize the structure. Such a model was developed that was based on the geometry of the unit cell of a single loop. The experimental work in this project involved using a set of 16 knitted fabrics that differ in course count and examining their pore structure and porosity related characteristics. The values of pore size and pore volume were calculated, those of pore size were measured with image analysis, and other parameters. The effects of course count and washing on stitch density, stitch length, fabric thickness and pore size are examined in details.

Knitted fabrics are characterized by comfort compared to woven fabrics due to their high extensibility and airpermeability, but they have lower dimensional stability after repeated washing especially single jersey knitted fabric(SJKF). Therefore, the spandex (Lycra) core-spun yarns are used to maintain the dimensions of knitted fabrics duringuse and after repeated stresses. In this study, nine elastic SJKF samples were produced at three levels of loop lengthand spandex percent using yarn linear density 30/1 Ne. For comparison, three 100% cotton knitted samples wereproduced with the same levels of loop length and yarn count. The dimensional and thermal comfort properties of thelong-stretch samples were compared with the short-stretch cotton knitted fabric. The thermal comfort properties (thermalconductivity, resistance, absorptivity, and water vapour permeability), air permeability, and dimensional properties weremeasured and compared to 100% cotton samples. The results showed that the stitch density, fabric density, fabricthickness, and thermal resistance increased, whereas the air, water vapour permeability, and spirality angle decreasedin cotton/spandex samples.

Analysis of the mechanism of action of surfactants in the conditions of washing cotton knitted fabrics, the establishment of surfactants for functional purposes, which should be part of the composition, and the study of changes in the surface tension of solutions of surfactants of various classes designed to create a composition for the preparation of cotton knitted fabrics. Determination of the surface tension of solutions of surfactants of different concentrations was carried out by the method of detachment of the ring, using the Du-Nui method. The paper presents the results of the analysis of the mechanism of action of surfactants in the conditions of washing cotton knitted fabrics, it is established what properties the constituents of the composition should possess and the surfactants that contribute to the maximum reduction in the surface tension of their solutions are determined. Scientifically substantiated the principles of creating surfactants compositions for the scouring of cotton knitted fabric on the basis of an analysis of the mechanism of their action and found that the wetting and washing abilities of surfactants are the determinants; the isothermal dependences of the surface tension of solutions of surfactants of various classes are first obtained. Surface-active substances and their concentrations are established, which ensure low surface tension of solutions.

Wastewater of baths after an exhaust dyeing of cotton knitted fabric with reactive dyestuffs, soaping and rinsing was investigated. It was found that the wastewater of rinsing baths after dyeing in a light shade, which had a small amount of dyes and electrolytes, could be used for dyeing or rinsing after dyeing in a dark shade. The dyes present in the wastewater can be removed by treatment with cross‐linked cationic starch (CCS) with a degree of substitution of about 0,3. In all cases wastewater must be filtered before reuse. Such a wastewater was used for dyeing of cotton knitted fabrics in a dark shade with a laboratory apparatus. It was found that the use of wastewater in the dyeing process was risky because in some cases the colour of coloured products did not satisfy colour standards. Filtered wastewater as well as that treated with CCS were used for rinsing after dyeing of cotton and viscose knitted fabrics in a dark shade with reactive dyestuffs in industrial‐scale experiments. The colour of dyed textiles satisfied colour standards, and the colour fastness to rubbing was good.

Organic cotton, which is produced without any chemical fertilizers and pesticides, is playing a vital role in creating a less harmful environment. An investigation of the properties of weft knitted fabrics produced from organically made cotton vis-à-vis regular cotton knitted fabric is reported. The yarn is made with both organically produced and regular cotton, and the fabric is knitted by using single jersey machines. The fabrics are subsequently dyed by using natural dyes. The naturally dyed knitted fabrics are examined for shrinkage, bursting strength, abrasion resistance, and colour fastness properties. The result shows that the knitted fabrics produced from organically grown cotton is superior in performance in comparison with fabrics produced from regular cotton.

In recent years, baby clothing has become an important role in the garment sector. The increasing importance of baby clothing, along with the new designs, different fabric structures, accessories and clothing comfort is required to develop. Due to the increasing importance given to baby health in the world, babywears have to be manufactured from materials that are not harmful to health in accordance with the standards. The purpose of this study is to investigate the effect of cotton knitted fabrics structure of babywear on moisture management properties. For this reason, moisture management properties (wetting time, absorption rate, spreading speed, accumulative one-way transport capability (OWTC) and overall moisture management capability (OMMC)) of cotton knitted fabrics of different structures which are widely used in babywear have been examined. Moisture management tester was used for liquid transport of the knitted fabric samples. As a result of the study, it is observed that single jersey fabric had higher OMMC values than these of interlock and 1x1 rib knitted fabrics. Regarding the effect of yarn thickness, liquid transport increased with decreasing yarn thickness in general. Regarding the effect of fabric weight and fabric thickness, liquid transport decreased with increasing weight and thickness in general. Negative correlations were observed between fabric weight, fabric thickness and overall moisture management capability.
