Introduction

Bleaching of textile grey fabrics is generally carried out to impart whiteness to textile fabrics by removing natural colouring matter. The process of dyeing is carried out to improve the marketability of textile products and also to suit the customer needs by adding colour. These two processes are generally carried out in open tank, kier machines, jet dyeing machines, jiggers, soft flow dyeing machines etc. For hosiery goods, it is carried out with winch machines, since it imparts very less tension during operation. Viable processing units can be set up as most of the fabric manufacturing units do not have their own processing units. In this report, details are provided for setting up the unit for bleaching and dyeing of cotton knitted fabrics.


Market Potential

The demand for hosiery garments is increasing due to its popularity in domestic and export market. There are number of units engaged in manufacturing of knitted cloth and most of these units are not having their own captive processing units. Bleaching and dyeing of knitted fabric produced by these units are normally carried out from outside on paying requisite processing charges. It is, therefore, presumed that setting up of textile processing units is economically viable.


Basis and Presumptions

This project is based on single shift basis with 300 working days in a year. Time period for achieving maximum capacity utilisation is considered from 3rd year from the date on which production is started. Rental value of the building is taken at Rs. 2 per sq. ft. Costs of machinery and equipments/materials indicated refer to a particular make and approximately to those prevailing at the time of preparation of this project.

Cost of installation and electrification is taken @ 10% of cost of machinery and equipment. Non-refundable deposits, project report cost, trial production, security deposit with Electricity Board are classified under pre-operative expenses.

Depreciation has been considered at 10% on plant and machinery, 15% on office furniture, fixtures, vehicle and 20% on testing equipments. Interest rate on capital loan has been taken @ 12% per annum.


Implementation Schedule

The implementation period required for executing this project right from selection of site to starting the trial run production will be 6 months.


Technical Aspects

Process of Manufacture

The knitted fabric to be bleached is thoroughly wet in a soap solution of 2% and piled in kier boiling pan containing 1.5% caustic soda, 2% soda ash and 1% lisapol etc. and allowed to boil for 6-8 hours. The cloth is washed well and taken to SS winches for bleaching using 2% bleaching powder and then washed thoroughly. This bleached cloth is scoured using hydrochloric acid of 1.5% concentration. After sometime, cloth is washed thoroughly to neutralise the traces of acid. In case of only bleaching the cloth is treated with optical whitening agent, thereafter, it is hydro-extracted, dried and calendered as final operations.

In case of dyeing, about 15-20% salts, 2% brightol C paste, 2-4% dyes as per shade are mixed and fabric is treated with the solution in winches. The cloth is allowed to run for several times in order to maintain uniform shade, thereafter, washed, hydro-extracted, dried and calendered.
