Production of Fused Polyester core with CottonWrapped Triple Rove Thermo core yarn fibre migration behavior and itsmechanical properties

Abstract:

In the production of canvas fabrics and in somesittings, three ply yarns are used to obtain a good quality. Thus it was feltthat the three ply yarns would confer better properties to the fabric than twoply yarns. In addition, these ply yarns also find application in sewing threadmanufacture. The effect of temperature, roving position twist factor and spindlespeed upon fibre migration behavior and its mechanical properties wereinvestigated in this study.

In case of treble rove yarn also, where twocotton ravings are placed at the edges and a polyester roving is made topresent at the center, the same fibre migration, as like double rove yarn,occurs.

The presence of polyester fibre at the sheathmay cause the following;

• More pilling
• Affects moisture absorbency
• Affects the physical properties of yarn
• Affects the appeal of the yarn

In order to overcome above problems in normalyarn, we are going implement a heater tube in traditional ring frame machine,at the nearest exit of the drafted strand, to control the migration ofpolyester component, and make it to go inside the yarn body. By doing this theyarn will be covered by maximum of cotton fibres and the inner will be maximumof polyester.
