Purpose In this study, which is divided into two parts, the silicone softeners having different properties and including different additives as glycerin, polyethylene glycol 400 (PEG 400) and polyethylene glycol 4000 (PEG 4000) (due to their high hydrophilic characters) are produced for the purpose of providing or developing the hydrophilic character, lubricity and filling properties of the emulsions. The paper aims to discuss this issue. Design/methodology/approach In the first part of the study, the produced silicone emulsions were characterized and applied to the 100 percent cotton-knitted fabrics. In addition, the mechanical properties and whiteness degrees of the fabrics were also researched. In this part of the study, the effects of the produced silicone softeners on the comfort properties of the fabric samples were investigated by qualitative handle, hydrophility, contact angle, air permeability, thermal comfort and moisture management tests. Findings The results showed that while classic silicone application improved mechanical comfort properties of the samples such as the handle and drape properties, they worsened other thermal comfort properties as hydrophility, transfer or dispersion of the moisture, and air permeability. In addition, the thermal comfort properties about heat transfer of the fabric samples were not significantly affected by application of the silicone softeners. All results were affected from the producing recipe of the silicone softeners, and generally the usage of the additives had positive effect on the comfort results depending on the producing recipe (especially type of the silicone oil) of the silicone softeners. Research limitations/implications In this study, the additives were used in single form; however, their dual or trio combinations and/or their different amounts can be used in the emulsions. Practical implications In order to enhance the hydrophilic character, lubricity and filling properties of the silicone softeners, they could be produced by using appropriate additives. Originality/value In the literature, there were not any studies about the silicone softeners including different additives. So the authors can say that the contribution of the additives to the recipes of the silicone softeners is a novel approach.

Purpose In this dichotomous study, the silicone-based softeners were produced with the contribution of some additives such as glycerin, polyethylene glycol 400 (PEG 400) and polyethylene glycol 4000 (PEG 4000) which had hydrophilic hydroxyl groups for providing or developing the hydrophilic character, lubricity and filling properties of the emulsions. The paper aims to discuss this issue. Design/methodology/approach The produced softeners were applied to the 100 percent cotton-knitted fabrics at different concentrations (owf%). In the first part of the study, the produced silicone emulsions were characterized via particle size, polydispersity index (PDI), zeta potential and TGA analyses. In addition, the effects of these emulsions on the mechanical properties of the fabrics were examined by bursting strength and pilling tests, and also the whiteness degrees (Berger value) of fabrics were researched. In the second part of the study, the effects of produced silicone softeners on the comfort properties of the fabrics were investigated. Findings According to the results, it was possible to say that the additives could be successfully added to the silicone emulsions, and they did not have a crucial effect on the properties of the emulsions or the mechanical and whiteness properties of the fabrics. Research limitations/implications In this study, the additives were used as single form in the softeners recipes; however, their dual or trio combinations and/or their different concentrations could be used in the softeners emulsions. Practical implications In order to enhance the hydrophilic character, the lubricity and filling properties of the silicone softeners, they could be produced by using appropriate additives. Originality/value The contribution of the additives to the recipes of the silicone softeners is a novel approach.

Purpose – The purpose of this paper is to present the thermal comfort properties of single jersey knitted fabric structures made from bamboo, tencel and bamboo-tencel blended yarns. Design/methodology/approach – Bamboo, tencel fibre and blends of the two fibres were spun into yarns of identical linear density (30s Ne). Each of the blended yarns so produced was converted to single jersey knitted fabrics with loose, medium and tight structures. Findings – An increase in tencel fibre in the fabric had led to a reduction in fabric thickness and GSM. Air permeability and water-vapour permeability also increased with increase in tencel fibre content. The anticipated increase in air permeability and relative water vapour permeability with increase in stitch length was observed. The thermal conductivity of the fabrics was generally found to increase with increase in the proportion of bamboo. Research limitations/implications – It is clear from the foregoing that, although a considerable amount of work has been done on bamboo blends and their properties, still there are many gaps existing in the literature, in particular, on thermal comfort, moisture management and spreading characteristics. Thus the manuscript addresses these issues and provides valuable information on the comfort characteristics of the blended fabrics for the first time. In the evolution of this manuscript, it became apparent that a considerable amount of work was needed to fill up the gaps existing in the literature and hence this work which deals with an investigation of the blend yarn properties and comfort properties of knitted fabrics was taken up. Originality/value – This research work is focused on the thermal comfort parameters of knitted fabrics made from 100 per cent tencel yarn, 100 per cent bamboo yarn and tencel/bamboo blended yarns of different blend ratios.

Thermal Comfort Properties

PurposeDesign of bedding textiles that contact the human body affects the sleep quality. Bedding textiles contribute to comfort sense during the sleep duration, in addition to ambient and bed microclimate. The purpose of this study is to evaluate the effects of different layer properties on the compression recovery and thermal characteristics of multilayer bedding textiles.Design/methodology/approachIn this study, woven and knitted multilayer bedding textiles were manufactured from fabric, fiber, sponge and interlining, respectively. Different sponge thickness, fiber and interlining weight were used in the layers of samples. Later, the pilling resistance, compression and recovery, air permeability and thermal conductivity of multilayer bedding textiles were investigated.FindingsThe results indicated that samples with the higher layer weight and thickness provide better compression recovery and lower air permeability properties. It was also found that knitted surfaces show the higher air permeability than the woven surfaces depending on the fabric porosity. Layer properties have insignificant effect on the thermal conductivity values.Originality/valueWhile researchers mostly focus on thermal comfort properties of garments, there are limited studies about comfort properties of bedding textiles in the literature. Furthermore, compression recovery properties of bedding textiles have also a great importance in terms of comfort. Originality of this study is that these properties were analyzed together.

Drying Properties

Engineered yarns are used to provide better clothing comfort for summer garments because of their high levels of moisture and water vapor management. The aim of this study was to investigate the characteristics of knitted structures that were produced using different types of polyester yarns in order to achieve better thermal comfort properties for summer clothing. However they are relatively expensive. Therefore, in this study engineered polyester yarns were combined with cotton and lyocell yarns by plying. This way, the pronounced characteristics of these yarns were added to the knitted structure as well. Channeled polyester, hollow polyester, channeled/hollow blended polyester, cotton, and lyocell yarns were plied with each other and themselves. Then, single jersey structures were knitted using these ply yarn combinations and air permeability, thermal resistance, thermal absorptivity, water vapor permeability, moisture management, and drying properties were tested. The results indicate that channeled PES fabrics are advantageous for hot climates and high physical activities with regards to high permeability and moisture transfer and also to fast drying properties. Besides, air permeability and thermal properties improved through the combination of lyocell yarn with engineered polyester yarns. However, the use of lyocell or cotton with engineered yarns resulted in a to a decrease in moisture management properties and an increase in drying times

Thermal Comfort Properties

Recent research on ballistic vests has focused on comfort performance by enhancing thermal comfort and moisture management. Kevlar/wool fabric has been developed as a potential material for ballistic vests. This study investigates the thermal comfort properties of woven Kevlar/wool and woven Kevlar ballistic fabrics. In this context, the thermal resistance, water-vapor resistance, moisture management performance, air permeability and optical porosity of 100% Kevlar and Kevlar/wool ballistic fabrics were compared. The effects of fabric physical properties on laboratory-measured thermal comfort were analyzed. This study also presents the fabric bursting strength and tear strength for comparison. Experimental results showed a clear difference in thermal comfort properties of the two fabrics. It was found that Kevlar/wool possesses better moisture management properties and improved mechanical properties than Kevlar fabric.

Thermal Absorptivity

PurposeThis paper investigates the thermal comfort properties of quilted (jersey cord) fabrics produced with different width of diamond pattern, different filling yarn linear density and different types of material.Design/methodology/approachA total of 12 fabrics were knitted by varying the width of diamond pattern (1 and 3 cm), the filling yarn linear density (300 and 900 denier) and the type of materials (cotton, polyester and their combination). In this regard, air permeability, thermal conductivity, thermal resistance, thermal absorptivity and relative water vapor permeability of these fabrics were measured and evaluated statistically.FindingsThe results showed that fabrics knitted using cotton yarn in both front and back surfaces exhibit higher thermal conductivity, thermal absorptivity and relative water vapor permeability characteristics; whereas samples knitted using polyester yarn in both surfaces have higher air permeability and thermal resistance. As the linear density of filling yarn increases, thickness and thermal resistance of the samples increase and air permeability, thermal conductivity, water vapor permeability characteristics decrease. When the effect of the width of diamond pattern compared, it is seen that an increase in the width of pattern lead to an increase in thickness and thermal resistance and a decrease in thermal conductivity, thermal absorptivity and water vapor permeability values.Originality/valueMany researches were carried out on the thermal comfort properties of knitted fabrics, however there is a lack of research efforts regarding thermal comfort properties of quilted fabrics.

Purpose – Sleep is a vital and a basic activity of human life and it is a physiological need for human body. Sleep quality is directly influenced by the comfort conditions of sleep environment. The purpose of this paper is to define the role of textile materials utilized as bed fabrics on air and mass transfer from the human body. Design/methodology/approach – Thermal conductivity, thermal resistance, thickness, water vapour permeability and air permeability properties of fabrics were analyzed and statistically evaluated. Thermal conductivity and resistance measurements were performed in Alambeta test instrument. Water vapour permeability tests were done according to the Rotating Platform method, and air permeability was measured in FX 3300 Textest air permeability tester. Relationships between comfort parameters were statistically evaluated with correlation analysis. Findings – Comfort is a major concept in the determination of overall life quality as well as sleep quality of a resting person. Therefore academic studies about thermal comfort prediction of sleep environment and bed surface fabrics are of great importance. This study investigates conventional mattress ticking fabrics in terms of comfort parameters and defines the important fabric properties on comfort parameters. Originality/value – Sleep comfort is a promising area in textile comfort studies with its dynamics different from body thermal comfort during daily life. However, in general comfort studies are about garment materials which are in direct contact with the skin. This study tries to define the comfort status of textile materials which have indirect contact with the human body surface during sleep duration.

Air permeability is one of the thermal comfort properties of clothing and fabrics. This study evaluated the air permeability properties of summer cooling towels of different brands available in the market, “Perfect Fitness”, “N-rit” and “Cooldyxm” and an anonymous ice towel. The air permeability function of the cooling towels was evaluated instrumentally. Other than the air permeability property, other fabric specification such as fiber composition, fabric type, fabric weight, fabric thickness, yarn linearity and fabric density were measured. Some specifications were found to have good statistical correlation with the air permeability. Based on the experimental results and statistical analysis, the sample of Perfect Fitness was found to have the poorest cooling effect, whereas N-rit, Cooldyxm and Ice Towel samples had comparable air permeability properties. The best performance of air permeability was seen in N-rit sample. The underlying reason could be ascribed to the fabric structure and thickness. This study can provide some information for choosing cooling towel for practical use.

Thermal Comfort Properties

Bifacial fabrics, with a single jersey on one face and a plain weave on the other, were produced on a purpose-built machine. Thermal comfort properties of bifacial fabrics were compared with conventional woven and knitted fabrics and the effect of weft density and loop length of bifacial fabrics on their thermal comfort properties was investigated. While different fabric structures were produced with the same wool, acrylic, and polyester yarns, the findings confirmed that the bifacial fabric is warmer (lower total heat loss) and more breathable (higher permeability index ( im)) than the corresponding woven and knitted fabrics. Increasing the loop length of bifacial fabrics enhanced evaporative resistance, air permeability, warm feeling, thermal resistance, and water vapor permeability index, yet reduced total heat loss. An increase in the weft density of bifacial fabrics led to higher evaporative resistance, warmer feeling, higher thermal resistance, lower air permeability, and total heat loss. However, the permeability index did not change with an increase in weft density. This study suggests that thermal comfort properties of bifacial fabrics can be optimized by modifying structural parameters to engineer high-performance textiles.
