TL;DR: In this paper , the 3-glycidyloxypropyl (GPTMS) and various long alkyl-chain alkoxysilanes were employed for the fabrication in the presence of a catalyst of a water-based superhydrophobic finishing for polyester fabrics with a simple sol-gel, non-fluorinated, sustainable approach and the dip-pad-dry-cure method.
Abstract: Polyester fibers are widely employed in a multitude of sectors and applications from the technical textiles to everyday life thanks to their durability, strength, and flexibility. Despite these advantages, polyester lacks in dyeability, adhesion of coating, hydrophilicity, and it is characterized by a low wettability respect to natural fibers. On this regard, beyond the harmful hydrophobic textile finishings of polyester fabrics containing fluorine-compounds, and in order to avoid pre-treatments, such as laser irradiation to improve their surface properties, research is moving towards the development of fluorine-free and safer coatings. In this work, the (3-glycidyloxypropyl)trimethoxysilane (GPTMS) and various long alkyl-chain alkoxysilanes were employed for the fabrication in the presence of a catalyst of a water-based superhydrophobic finishing for polyester fabrics with a simple sol-gel, non-fluorinated, sustainable approach and the dip-pad-dry-cure method. The finished polyester fabrics surface properties were investigated by static and dynamic water repellency tests. Additionally, the resistance to common water-based liquids, abrasion resistance, moisture adsorption, and air permeability measurements were performed. Scanning electron microscopy was employed to examine the micro- and nano-morphology of the functionalized polyester fabrics surfaces. The obtained superhydrophobic finishings displayed high water-based stain resistance as well as good hydrophobicity after different cycles of abrasion.

TL;DR: In this paper , a comparison between different ways to mordant cotton yarns with different molecular weight chitosan was made, and it was observed that the mordanting processes performed with chitoshan contributed to the increase in the color strengths, and higher color depths were obtained with the increasing chitosa concentration.
Abstract: ABSTRACT Problems such as the depletion of natural resources and the increase in environmental pollution brought about by industrialization, the concept of recycling gained great importance. Natural dyes have gained importance again with the increase in environmental awareness. For this purpose, the dyeability of recycled cotton yarns with natural dyes was examined in order to both protect natural resources and reduce the waste water load in dyeing. The paper also discussed a comparison between different ways to mordant cotton with different molecular weight chitosan. Although it was seen by FTIR analysis that cotton fibers were dyed, the presence of chitosan could not be clearly seen. It was explained by the use of low amounts of chitosan. It was observed that the mordanting processes performed with chitosan contributed to the increase in the color strengths, and higher color depths were obtained with the increasing chitosan concentration. Simultaneous mordanting in Curcuma longa dyeing, mordanting before Sandalwood dyeing provided higher color depths than others. The washing fastness of the samples dyed with Curcuma longa revealed the necessity of fastness improvement processes. It was concluded that chitosan mordanting process was effective in terms of sustainable natural dyeing, but it was necessary to improve fastness. Graphical Abstract

TL;DR: In this article, the influence of variables such as loop length, the presence of an elastomeric component and fabric structure on the air permeability of cotton single jersey and pique knitted fabrics in a stretched state was critically analyzed.
Abstract: Most of the time, a certain degree of stretch prominently and incrementally occurs in intimate wear, leisure wear, sportswear, medical textiles etc., during their action. Variations in the stretch gradient would definitely cause changes in the air permeability of knitted fabrics. The influence of variables such as loop length, the presence of an elastomeric component and fabric structure on the air permeability of cotton single jersey and pique knitted fabrics in a stretched state was critically analysed. In this work, changes in the air permeability of cotton jersey samples with and without elastomer were investigated and reported by keeping the samples in static up to an incremental stretch of 40% at a rate of 10% of the stretch gradient, in a dry relaxed state, wet relaxed state and fully relaxed state.

TL;DR: In this article , the influence of core-sheath ratio, twist and loop length on the moisture management properties of the knitted fabrics made from cotton/polyester core-spun yarns was investigated.
Abstract: Moisture management is one of the essential properties required for knitted fabrics. Generally, the moisture management fabrics regulate the heat and moisture by maintaining the body temperature and keep the wearer cool and comfortable. Cotton fibres are known for their excellent properties in clothing to be worn in a normal situation by managing a limited quantity of sweat. During any sports activity, the human body dissipates a greater amount of sweat for an extended period of time and cotton fibre blended with polyester is generally recommended for its low moisture absorption and durability. In recent years, polyester fibres are most widely used for sportswear applications due to their better moisture transmission properties. This study mainly focuses on the influence of core-sheath ratio, twist and loop length on the moisture management properties of the knitted fabrics made from cotton/polyester core-spun yarns.

TL;DR: The FTIR analysis interpreted as polyester might have been mixed during processing into recycled cotton and the presence of chitosan in the blend could be indicated by decreasing band intensities compared to cotton as discussed by the authors .
Abstract: ABSTRACT The cultivation and wet processing of cotton is very harmful to the environment. Recycling of cotton is an important way to reduce its environmental impact. For this purpose, recycled cotton by using it in a mixture with chitosan yarns and the dyeing behavior of fabrics produced from this blend were examined within the scope of sustainable production. Among the reactive, direct and acid dyeings, the highest color depths were obtained from dyeing with direct dye in alkaline medium and in the presence of salt. It was observed that the dyeing temperature was important for leveling dyeing. The fastness results of reactive dyeing were higher than the others. The FTIR analysis interpreted as that polyester might have been mixed during processing into recycled cotton and the presence of chitosan in the blend could be indicated by decreasing band intensities compared to cotton. The SEM images supported the presence of chitosan in the blended fabric. According to the TGA results, the change in temperature at which the maximum weight loss was observed in the blended fabric approached to that of chitosan. The results showed that chitosan and cotton obtained from recycling could be used as a mixture instead of cotton. Graphical abstract

TL;DR: The skin environment least likely to be associated with diaper dermatitis is one in which Increases In both skin wetness and skin pH are minimized.
Abstract: The strength of the association between diaper dermatitis and measurements of skin wetness and skin pH was evaluated by statistical analysis of four diaper trials involving 1601 infants. Although the strength of the association between skin wetness and diaper dermatitis was greater than that between skin pH and diaper dermatitis, increases in wetness and pH were both significantly associated with elevated mean grades for diaper dermatitis. The skin environment least likely to be associated with diaper dermatitis is one In which Increases In both skin wetness and skin pH are minimized.

TL;DR: In this article, the influence of fabric's structure on the thermal and moisture management properties of knitted fabrics made of two types of yarns with thermo-regulating effect was studied.
Abstract: This paper studies the influence of fabric’s structure on the thermal and moisture management properties of knitted fabrics made of two types of yarns with thermo-regulating effect: Coolmax ® and Outlast ® . The main purpose of this study was the selection of the most adequate fabric, to be used in summer and winter sportswear. The results demonstrated that some properties, such as, thermal properties, diffusion ability, air and water vapor permeability are influenced by both raw material type and knitted structure parameters. Wicking ability is influenced to a greater extent by the knitted structure, while the drying ability is primarily determined by raw material and to a lesser extent by the knitted structure parameters. Outlast ® fabrics are preferred candidates for warmer climate sportswear, particularly due to their lower thermal resistance, higher thermal conductivity and absorptivity, air and water vapor permeability. When considering sportswear for colder weather, Coolmax ® based structures seem to be the best choice. These findings are an important tool in the design of a sportswear product tailored to the different body areas thermal and moisture management requirements.

TL;DR: In this article, the authors investigated the moisture management properties of double face fabrics and found that polypropylene (inner)-cotton (outer) fabric has better moisture management property, provides high levels of comfort and can be preferred for summer, active and sports.
Abstract: Double face fabrics are used to ensure better clothing comfort in sports and active wears. High moisture transfer properties of these fabrics affect their comfort properties and make them more functional. In this study, in order to investigate the moisture management properties of the double face fabrics, a special knitting structure, which has different or same yarn combinations in the face and back sides, was used. The selected yarns were cotton—cotton, cotton—polypropylene, polypropylene—cotton and polypropylene—polypropylene for face and back sides respectively. Moisture management properties and the changes of the thermal absorptivity values, which determine the warm-cool feeling, of the produced fabrics were determined and statistically analyzed. All measurements were done both in dry and wet conditions. The results indicate that, the polypropylene (inner)-cotton (outer) fabric has better moisture management property, provides high levels of comfort and can be preferred for summer, active and sports...
