Textile Testing Methods included in this section are all free to use and all the information were collected from the people who have been still serving in textile testing labs till now. You may feel free to contact us regarding any testing procedure explained in this website.
Quality Control system is to control the quality almost after the particular operation or process is finished. Eg. Measuring finished width, CSP, fastness properties etc. This is like a postmortem work.
Whereas Quality Assurance is taking proactive steps to get the desired results. Eg. Making the fabric to a higher width keeping sufficient allowance for shrinkage, selecting the right dyestuff for acquiring the demanded fastness levels etc.
In any good dye house Quality Control and Quality Assurance systems should go hand in hand. The knowledge of QC operations should lead to the formation of good QA system.
The basic input to any wet processing unit is water. Water quality decides the quality of further processing. Water decides the economy of the use of processing chemicals and water is decides the quality of final product's quality.DETAIL
In textile wet processing, we are using a lot of inorganic and organic basic chemicals at various stages. Basic inorganic chemicals we use in textile wet processing are, caustic soda, soda ash, sodium bicarbonate, Tri Sodium Phosphate, Sodium Bisulphite, sodium sulphate, sodium chloride, sodium sulphide etc. Organic basic chemicals are Acetic acid, Formic Acid, Oxalic acid, Tri-ethanol-amine etc. The quality of each ingredient plays an important role in the final quality of the processed goods.DETAIL
Parameters like width, length, thickness, density,specific gravity, tensile strength, breaking strength, GSM.shrinkage %, etc., decides the quality of source fabric/ yarn as well as some chemical inputs. Testing and recording the input parameters eliminates a lot of unwanted risks that we face after processing. A physical inspection for stains on incoming fabric or yarn gives you first hand knowledge of the greige input. If it is stained at loom stage or spinning stage you can very well point out and ask the concerned people to do quality control measures.DETAIL
Testing standard parameters of auxilairy chemicals is very important. There are many competitors claiming their products ae equivalent or better than a particular one we are using at present. Moreover some vendors claim that their products have some unique special properities that we cannot find with others'.
All these things to be proved in addition to the batch to batch supply uniformity in quality.Only if we are using a known quality at known dosage we can produce a consistent quality fabric. To safeguard this we should have proper procedure and method of testing and recording the quality of auxiliary chemicals.DETAIL
