Analysis of Cotton Yarn Properties Spun on Aerodynamic Compact and Open-End Rotor Spinning

Abstract

This article presents a comparative analysis of the properties of cotton yarn spun on aerodynamic compact spinning and open-end rotor spinning systems. Yarn samples with a linear density of 50 Tex, 37 Tex, 30 Tex, 25 Tex, and 20 Tex were spun both on the aerodynamic compact and rotor spinning systems using the same finisher drawn sliver of medium staple cotton which were produced by a specific mixing. The quality parameters such as mass variation, imperfection index, hairiness, and tensile behavior (strength in count strength product, elongation percentage) of the yarn samples were assessed and analyzed. The results revealed that aerodynamic compact spun yarn had a lower unevenness and mass variation, a higher imperfection in case of a finer count, less hairiness, higher tensile strength, and lower elonga-tion% compared to the open-end rotor spun yarn samples. Finally, pairedsamples t-test and regression analysis were carried out by using IBM SPSS 25 to check the significance of yarn quality parameters and correlation among them.

Investigation of the performance of okra fiber in woven fabric

“…Mass variation was expressed in terms of unevenness (U%) and co-efficient of variation (CVm%). Imperfection index (IPI) value represent the total number of thick place (+50%), thin place (−50%) and neps (+200%) per 1000 m of yarn [ 33 ]. Yarn hairiness (H) corresponds to the total length of protruding fibers in centimeter, cm (only higher than 4mm) per cm length of yarn [ 33 ].…”

Yarn hairiness (H) corresponds to the total length of protruding fibers in centimeter, cm (only higher than 4mm) per cm length of yarn [ 33 ]. Yarn strength and elongation was tested by Titan Universal Testing Machine - James Heal under CRE (constant rate of extension) principle according to ASTM D 2256 standard for 250 mm of test length, 250 mm/min test speed and 100 N load cell.…”

A comparative analysis for the cleaner production of vortex spun yarn based on the nozzle position

“…All of the experiments were conducted in normal conditions (65% relative humidity and 20 °C) [ 32 , 33 ]. IBM SPSS Statistics was used to conduct the statistical analysis [ 34 ]. The link between two variables was tested using the paired-samples t-test method.…”

Optimization analysis of combing box for air yarn based on computational fluid dynamics

“…According to previous studies, 9,13,14 many of the design parameters of a detachable nozzle are thought to affect the airflow characteristics. One of the biggest issues related to the actual design of the nozzle is that the parameters of the nozzle will result in negative vortex flow in the nozzle.…”

“…Using computational fluid dynamics (CFD), Islam, Ahmed and Siddik 14 developed a two-dimensional computational model of the transfer channel. He analyzed the effects of the size of the transfer channel inlet, the ratio of the circumferential velocity of the barbed roll to the mean flow velocity and the Reynolds number on the airflow pattern of the transfer channel.…”
