A clear awareness of quality parameters, the terminologies used in testing and passing a particular material, are all very crucial and important for every textile dyer, exporter and manufacturer.
The Textile processor should know the parameters of buyer's requirements in quantitative terms and only then he can take necessary measures to attain that standard. Textile processing is a vast ocean making use of so many processes, chemicals, machinery and men.
A clear cut policy on Quality Assurance and Quality control are a must for any good wet processing industry. Right from fiber to finished goods there are so many inputs and outputs. A systematic quality control procedure is essential to eradicate final quality problems of dyeing and finishing.
For example the cotton fiber test - for it maturity, staple length, color, moisture content etc determines what quality of final yarn and thereafter the fabric, the unit is going to produce. The physical tests such as TPI, Tensile strength, CSP etc. and EPI and PPI foretell the quality of yarn and fabric respectively.
The final quality of finished products may be assured if proper quality control measures are adopted in testing the incoming dyestuff and chemicals regularly. The technique of doing these tests is though not a complicated, a proper guidance is necessary.
Textile fabric or yarn before going for the next phase of processing, eg., garmenting or weaving/knitting, has to be tested for the required quality standards stipulated by the buyer. The tests like wash fastness, rubbing fastness, anti-staining properties, fire retardant, water repellent etc have to be conducted in the in-house laboratory and a prior assessment should be made before sending the product for 3rd party testing.
Nowadays the instrumental shade passing (Color Computer), shade matching, light and other fastness testing are all become mandatory to be fit for a highly competitive export market.
