Generally, ring spun yarns are manufactured from roving which is produced by frame. In this paper, an experiment has been done producing cotton yarn directly finisher drawn sliver eliminating the Total 3 types of with various linear density 8 Ne, 10 Ne & 12 were using a frame and without next step, physical mechanical properties those including unevenness, imperfections, hairiness tenacity inve...

Yarn quality is judged according to the achieved values of tested yarn properties that are selected in dependence on yarn utilization. Quality level of the yarns can be assessed using the USTER® STATISTICS [2]. This tool is composed of graphs enabling users to compare their measured results of yarn (sliver, roving, fiber) with the corresponding worldwide established fibrous product quality refe...

In this paper, the theory of the ballooning yarn has been adapted to the loop spinning process. The aim of a numerical simulation of high-speed winding process consists in establishing the shape of the curve of rotating yarn in the section between the gripping line of drafting motion rollers and the place where the yarn is wound upon a tube, and in determining the tensile force in the yarn in t...

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...
