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. There will, therefore, be a considerable increase in the demand for cotton that is suitable for blending with polyester fibers. If only imported cottons are to be considered for these blends, the demand cannot be met. Suitable Indian cottons will, therefore, have to be used as substitutes for these cottons. In making the choice of suitable Indian cottons, test data on blend yarns using Indian cottons would be required. ATIRA has, therefore, decided to issue to its member mills a series of reports giving such data as well as information on the processing conditions used. 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. It should be pointed out that in these spinnings the Indian cottons will be carded using the processing parameters that would normally be used for carding cottons for superfine spinning. This procedure is being followed because earlier experiments in ATIRA have shown that 'super carding' is a good means of upgrading Indian cottons. It is, therefore, expected that super carding will enhance the suitability of Indian cottons for use in blends with polyester fibers. This is the first report of the series, and gives data on 40s and 60s yarns spun from Shankar-4 and ISC-67 cottons blended individually with polyester fibers of 38 mm and 1.2 denier.
