ABSTRACT

Purpose - The purpose of this research is to investigate an alternative approach that can develop and assess the fabric made from twist less weft yarn.

Design/methodology/approach- The fabric was produced with twist less yarn. The cotton yarn was produced without twist by means of doubling with PVA filament in the opposite direction. This process was done by TFO (Two for One Twister) machine. The doubled yarn with PVA has sufficient strength required for weaving. This yarn has been used as weft in fabric to be formed. This soft twist weft yarn fabric is compared with standard sample and various properties are observed. The yarn with twist is considered as standard sample.

Findings The structure of fibrous assemblies in weft has great impact on the comfort related properties.

Originality/value Development of soft and smooth effect on the surface of the fabric with PVA winded weft. Soft twist weft yarn fabric is compared with standard sample and various properties are observed.

Introduction

Soft twist fabrics are used in various fields because of their water absorption and wicking properties. The marketing conditions which prevail in todays world market oblige manufacturers to constantly raise the level of usability of there products. Generally fabrics are made from twisted yarns. In this case moisture absorbency of the material is to a limited extent. To improve the moisture absorbency of the fabric we may use twist less yarns. The smoothness will be improved if the moisture absorbency is more in twist less yarn. Then feel of the fabric will be soft. Therefore this type of fabric is used in medical purpose. To manufacture baby wears. It can be also used for medical purposes because of their soft feel. It can be also used as baby wears so that we can prevent them from diseases. It improves the fabric absorption, wetting and wicking properties.

Method

Fiber selection

The cotton weft yarn is produced by open end spinning method. Yarn count is in the range of 20s Ne. Normally the fiber span length for this count is short staple length. But here, the fiber length is somewhat higher than the normal selection. Because the piles have no twist after processing, so it has to bind between two picks of weft yarn. In this regard the higher fiber length survives more gripping compare to short staple length. The fiber length and count of yarn are given below:

The fiber selection for 20^s Ne is accordingly same as 20s Ne mixing. So the yarn properties are comparatively increased, the increased properties were yarn strength, surface uniformity, better fiber cohesion and quality is better than that of normal mixing yarn. And, this higher fiber length is used for better gripping between two weft threads. So the fiber worn out from the surface of the fabric is to be control.
