Blended Yarn Analysis: Part I—Influence of Blend Ratio and Break Draft on Mass Variation, Hairiness, and Physical Properties of 15 Tex PES/CO Blended Ring-Spun Yarn

Abstract

This study was undertaken to investigate the effect of P/C blend ratio and break draft on yarn quality and physical properties. 15 tex yarn samples were spun from three blend ratios, i.e., P/C 30/70, 50/50, and 70/30 at ring frame with six break drafts (1. 35, 1.38, 1.42, 1.45, 1.49, and 1.53). The results of blend ratio were analyzed through linear regression technique to predict correlation between two variables. Strong correlation observed between blend ratio and yarn quality and physical properties, as the share of polyester increased all yarn characteristics improved. Prominent improvement in yarn mass variation and hairiness was observed when polyester percentage increased from 30% to 50% whereas tenacity and elongation improved more remarkably when polyester share increased to 70% from 50%. Most of the yarn characteristics were found optimum at break draft 1.49.

Prediction of Blended Yarn Evenness and Tensile Properties by Using Artificial Neural Network and Multiple Linear Regression

“…The second influential parameter according to rank analysis of optimised ANN model is break draft for yarn evenness and tenacity, whereas it is cot hardness for yarn elongation. It also confirms previous findings [4,22] that proper break draft is important for roving preparation for main draft and to avoid drafting wave. Twist multiplier ranked third influential input parameter in optimised models of tenacity and elongation, whereas it is cot hardness in yarn evenness model.…”

“…In previous research [4,5] the significance of aforementioned parameters on PES/CO blended yarn quality and tensile properties was explored experimentally but it is challenging to develop relationship between yarn properties and collective machine and material parameters analytically. As discussed earlier, there exist complex interactions among yarn quality characteristics and machine and material variables, and in such conditions, conventional mathematical techniques which require assumptions and constants are not much suitable to predict yarn properties with high precision.…”

Effect of Blend Ratio on Cotton-Modal Fibre Blended Ring- Spun Yarn Quality with Varying Modal Fibre Percentage

“…Blending of different types of fibres is practiced to enhance the quality characteristics of yarn by incorporating desirable properties of constituent fibres and to reduce the cost [2,3]. Fibre blend ratio is an important factor that determines the properties of spun yarn and is specified by the types of fibres and their ratio in the resultant mixture [4][5][6]. Among the different blends cotton-polyester, cotton-wool, wool-acrylic, cotton-nylon, jute-acrylic, cotton -rayon etc.…”

Modal–Cotton Fibre Blend Ratio and Ring Frame Parameter Optimisation Through the Taguchi Method

“…Blending of different types of fibres is practiced to enhance the quality characteristics of yarn by incorporating desirable properties of constituent fibres and to reduce the cost [2]. Fibre blend ratio is an important factor that determines the properties of spun yarn and is specified by the types of fibres and their ratio in the resultant mixture [3][4][5]. Modal fibre, a regenerated viscose fibre having better characteristics such as strength, moisture absorption, length uniformity, shrinkage, softness and appearance, is found to be compatible to blend with natural cotton fibre in different blend ratio to produce modal-cotton (MC) blended yarn.…”
