This research aims to analyze the environmental impact of six fibers in textile industry: conventional and organic cotton, silk, jute, flax, polyester. The study used a life cycle assessment (LCA) methodology with cradle-to-gate system boundary analyzed stages agriculture, spinning, weaving, dyeing. In agriculture production, five categories (i.e., fossil resource scarcity, global warming, land...
The physical and dimensional characteristics, i.e. course wale spacing, stitch density, tightness factor, diameter, porosity, stability bursting strength of single jersey knitted items containing lycra yarn with the variations in length content have been examined a detail investigation on filament has discussed this study. Six different samples were identical cotton but contents length. After c...
We present a balanced method for realistic rendering of towels and carpets from a normal viewing distance. Since the yarn loops on the surface of a towel contribute more to the appearance of a towel than the underneath skeleton yarns do, we model yarn loops with more accurate geometry and lighting models. To show the randomness in the shape of a yarn loop, we control the shape of yarn loops by ...
This paper defines a PID type yarn tension control run by a PLC system that is used to control the yarn tension below the twisting head of the novel air jet texturing and twisting (AJT) machine. In the standard sequence of the AJT, if the yarn is transported to the twisting and winding head with a low tension value, the yarn is bound to wrap around the shoulder below the twisting head and break...
Cotton is one of the most-used natural fibres in world due to its relative comfort and strength compared with other fibres. However, processing cotton for manufacturing products consumes a lot water, while harvesting uses significant amounts pesticides. One solution this ecological problem recycle waste. This study investigated effect blending virgin two categories denim waste—sourced during wi...
The textile and apparel production consumption generate a huge amount of solid waste. Mechanical recycling is one main method to recycle cotton waste; however, shredding in mechanical shortens fiber length reduces quality. As result, the application mechanically recycled textiles may be limited. This research investigated methods post-consumer waste designed developed second-life products. stud...
The article is devoted to the actual problem of developing a woven material that would protect against electromagnetic radiation and meets modern requirements for functional performance properties, as well technology its manufacture. analysis works revealed this topic has not been sufficiently studied. To solve posed in work, it necessary: analyse complex yarn obtained by connecting ferromagnet...
To growers, stickiness means higher costs for insect control and reduced cotton marketability. To ginners, stickiness may mean special handling and processing requirements. At the textile mill, stickiness means reduced processing efficiency, lower yarn quality, and in severe cases total shut down. For everyone concerned, stickiness means reduced profitability. Stickiness occurs when excessive s...
Relative performance of the back propagation neural network (BPN) algorithm combined with genetic algorithm (GA) approach for the prediction/optimization of the properties of yarn produced on jet ring spinning system has been studied. Yarn samples of various linear densities have been produced on ring spinning machines using air-jet nozzles as retrofit by varying the nozzle parameter and the ya...
