Creating aesthetics and functional values in cotton fabrics through the introduction of thermobonding amorphous polyester fibers into blends

Low‐melting thermobonding PET (copolymer) fibers were used to produce heather effects in fabrics blended with cotton, which could be classified as natural 100% cotton fabrics. PET (copolymer) fibers produced at relatively low molecular weights with intrinsic viscosities of 0.57 and 0.47 were used in this investigation. These were mostly amorphous fibers that showed a low specific gravity at 1.27 g cm^?3. The fibers were blended with cotton to produce open‐ended spun yarns without the PET component being melted. These yarns were knit into fabrics and cured. The curing was based on the thermal behavior of these fibers as observed in differential scanning calorimetry thermograms. The amount of pigmented PET copolymer needed to achieve the required heather effect was optimized by variations of the blend ratios. This approach provided another avenue for introducing additional functional properties, such as antibacterial and soil‐resistance properties, to the fabric. Both the fibers and resultant fabric properties were studied extensively, along with the finishing of these fabrics. © 2003 Wiley Periodicals, Inc. J Appl Polym Sci 89: 3747–3756, 2003     

Moisture and heat transfer in hybrid weft knitted fabric with artificial intelligence

One of the most important properties of clothes is their ability to help the body's thermal system to keep the body temperature in its natural range, even if the environmental conditions or physical activities are outside the body's ideal range. Perspiring is one of the most important effects of physical activities in warm weather for shedding the body's excessive heat. Therefore, the basic requirement of a fabric worn next to the skin is to transfer this moisture to the atmosphere to reach comfort through the avoidance of a feeling of wetness and clamminess and also through the generation of a situation for the best surface evaporation of moisture. The main goal of this study was to achieve a kind of fabric that guarantees comfort for the body by good heat and moisture transport. To achieve this goal, a group of double‐surface fabrics containing hydrophilic and hydrophobe fibers were knitted, and their simultaneous heat and moisture transport was evaluated with the help of a perspiration‐simulation machine; the results were analyzed as transfer process plots. Also, the transmission of heat and moisture was evaluated for all of the samples by differential modeling as an artificial neural network. Effective parameters on heat and moisture transfer were taken into consideration with modeling and statistical methods. The results were analyzed to find a suitable fabric with optimum comfort. The final results showed that a fabric made of micropolyester filaments and cotton yarns on the bottom and top surfaces, respectively, had the best heat and moisture transfer. © 2009 Wiley Periodicals, Inc.

Dye distribution in the dyeing of mixed denier polyester fabrics

Microfibre polyester is sometimes blended with higher denier fibres to achieve good aesthetic effects at lower cost. Two polyester yarns of 1.4 and 0.7 denier were dyed singly and together with a range of depths of CI Disperse Blue 79, and the dye distribution over the course of the dyeings was examined. The uptake is initially greater on the microfibre, but as dyeing is continued the distribution becomes more even, and eventually the same concentration of dye is present on both fibres. Based on the common observation that a given concentration of dye produces a lighter shade on a microfibre, the redistribution of dye during the process causes a continuing shade change even though the bath exhaustion is constant. A mixture of three dyes produced a stable hue on a fabric of 1.0 denier polyester after 20 min at a fixed dyeing temperature, but when dyed on a fabric of 1.0 and 0.5 denier yarns, a change in hue continued for more than 60 min.
