Studies performed in recent years have shown that the spinning triangle in conventional ring spinning has a noticeable effect on the yarn surface (hairiness), yarn strength, yarn elasticity, processing performance and fly formation [1]. Therefore, new researches were concentrated on decreasing the spinning triangle [2]. As a result of these studies, a new spinning system has been developed called compact spinning, which decreases the yarn hairiness to a great extent [3].Compact spinning, which is a new version of ring spinning, produces a new yarn structure as the edge fibers are incorporated into yarn due to the minimization or elimination of the spinning triangle, and the harmful effects of the spinning triangle on yarn characteristics are eliminated [4]. The most apparent features of these yarns are their high strength and elongation values, and low hairiness [5][6][7]. Compact spinning also attempts to reduce fly liberation during conventional ring spinning by using pneumatic compression [8]. When using compact yarns in the knitting process, the practical applications offer some advantages such as decrease in abrasion, dust and fly, thus decreasing the cleaning costs, less needle breakages, and less fabric faults [9]. 1 In this study, different knitted structures were produced with compact and conventional ring yarns. The physical properties of fabrics were evaluated before and after the pre-treatment and dyeing processes and compared with each other statistically.Abstract This study investigated the differences between knitted fabrics made from compact and conventional ring-spun yarns. 100% cotton yarns, produced from the same cotton blend, were spun according to compact and conventional ring spinning principles in two different yarn counts and twist factors. Three different knitting structures, i.e., interlock, rib and single jersey, were produced from these yarns. The physical properties of these fabrics were investigated and compared with each other before and after the reactive dyeing process. When the results were examined, it was found that the hairiness of compact yarns was less and the strength and elongation percentages were higher, the fabrics produced with compact yarns showed less tendency to pilling and had a higher bursting strength. No statistical differences were observed with regard to spirality, weight, abrasion resistance, color efficiency and rubbing fastness of the fabrics produced with compact and ring-spun yarns.

In this study, linen fabrics were inkjet printed with reactive dyes after air argon plasma treatments. Sodium alginate (ALG), carboxymethlycellulose (CMC), chitosan (CHT), ALG+CHT, CMC+CHT, and their combinations, were used as pretreatment print pastes prior to plasma pretreatment. The color yield and the fastness properties of the printed fabrics were evaluated. The CMC+CHT pretreatment print paste gave the best color yield with or without plasma pretreatment. Colorfastness values were not affected by the type of pretreatment print paste. However, plasma pretreatment slightly improved the colorfastness.

Ring spinning is still accepted as the most important method in short staple spinning, and in spite of the new spinning methods which came on the scene with the purpose to increase the production, ring spinning is still in the first category owing to its continuous development. Studies in recent years showed that spinning triangle in conventional ring spinning has a noticeable effect on yarn hairiness, yarn strength, yarn elasticity, processing performance and fly formation [1]. After this determination, studies were intensified on decreasing the spinning triangle [2]. As a result of these studies, a new spinning system was developed which was named compact spinning and which decreased the yarn hairiness to a great extent [3]. Literature SurveyIn compact spinning, a different yarn structure is produced. Most apparent features of these yarns are their high strength and elongation values and low hairiness [4][5][6]. When using compact yarns in knitting process, practical applications offered some advantages, such as decreases in abrasion, dust and fly, thus, decreas 1 ing cleaning costs, needle breakages and fabric faults [7].In this study, in the light of the existing information about compact spinning, possibilities of the system have been investigated in detail on the basis of yarn by using compact and conventional ring yarns in different fineAbstract Compact spinning is a new version of ring spinning and the most distinct features of these yarns are their high strength and elongation values and low hairiness. In this study, we attempted to find the differences between compact and conventional ring knitted fabrics. One hundred % cotton yarns, produced from the same cotton blend, were spun according to compact and conventional ring spinning principles in two different yarns counts and twist multipliers. Three different knitting structures, interlock, rib and single jersey, were produced from these yarns. The physical properties of these fabrics were investigated and compared with each other before and after the printing processes. When the results were studied, it was seen that hairiness of compact yarns was less and their strength and elongation percentages were higher. They showed less tendency to pilling and had higher bursting strength. No statistical differences were observed with regard to weight, abrasion resistance, color efficiency and rubbing fastness.

In this study, 100% cotton fabrics' flame retardant properties were improved using commercial nanoclay (Cloisite 20A), clay-based montmorillonite. Flame retardancy and thermal decomposition behavior of the samples were characterized by the vertical burning test, limiting oxygen index (LOI), and thermogravimetric analysis (TGA). The surface morphology of untreated and treated fabric was examined using a scanning electron microscope (SEM). Fourier-transform infrared spectroscopy (FTIR) analysis was carried out for Cloisite 20A, untreated, and coated fabrics. The test results showed that the coating treatment, even at low nanoclay concentration, is enough to have a considerable flame retardant effect. This result was attributed to the barrier effect of the nanoclay.

Softeners are of great importance in textile processing. The aim of this treatment is to achieve a soft handle to facilitate the processability and improve wettability. In this study, it was aimed to investigate the effect and washing durability of various softeners on handle properties of cotton and bamboo knitted fabrics. Six types of softeners were applied to the fabrics. Moreover, the washing durability of the softeners after 5, 10 and 20 washing cycles were tested. Handle characteristics such as drapeability, kinetic friction coefficient and circular bending rigidity were measured. The results were statistically evaluated. It was determined that softening treatment does not have a successful performance in bamboo fabrics as it has in cotton fabrics.
