Use of Indian Cottons in Polyester-Cotton Blends

摘要

The production of polyester fibers in India will increase manifold in the very near future. It is to be expected that the bulk of this will be consumed in blends with cotton and viscose. The series will cover a number of yarns spun using different Indian cottons, in varying blend proportions with polyester fibers of different lengths and deniers. This report, the second in the series, gives data on 32s, 40s and 50s yarns spun from Sankar-4, Digvijay and CO2 cottons blended individually with polyester fibers of 32mm and 2.2 denier. The most commonly used fiber length for polyester fibers in India at present is 38 mm, but this is generally blended with imported cottons with effective length 36 mm to 38 mm. As Indian cottons are of shorter length, a shorter staple polyester fiber was thought to be more compatible, and therefore 32 mm fibers have been used. The use of 32 mm fibers could also be expected to result in fewer crackers in bulk spinning with short cradles which are available in practically all the mills. (Copyright (c) 1973.)
