Modern textile testing and quality control equipment

Modern textile testing and quality control equipment:




Quality: Quality is the attribute of the products that determines its fitness for use, or according to Japanese Standard (JIS), textile (fibre, polymer, yarn, fabric) quality is all specific properties and performance of a textile product or service that can be evaluated to determine whether a product or services satisfactorily meets the purposes of its uses. The level of quality is measured by “ inherent properties and performances which is the subjects of evaluation or the characteristic related to its phsico-mechanical or chemical properties, dimension, longevity, durability utilization or any other requirement used to define the of the product or service is known as “quality characteristics”.

Standard: It is an agreed document established mainly with respect to technical matters related directly or indirectly to an article or service. So that profit or convenience may be obtained with fairness among the person concerned.

Testing:  The way to control or the way to check or verify the nature & characteristics. Or, the way to checking or verifying.


Modern Fibre or Polymer Quality Testing Equipment:
Fibre characteristics must be classified according to a certain sequence of importance with respect to the end product and the spinning process. Moreover, such quantified characteristics must also be assessed with reference to the following

Modern Fabric Quality Testing Equipment:

Textile fabrics are made for various purpose, each of which has different performance needs. The chemical and physical states of textile fabric identify what will the end use of this, and ultimately whether it is reasonable for a specific use. Fabric testing makes a crucial role in gauging product quality, ensuring regulatory compliance and assessing the perfection of textile materials. It provides information about the physical or structural, chemical and performance properties of the textile. As user become more aware and more demanding of products, the number of tests required for textile fabrics has grown. As a result the testing of fabrics is increasingly varied, in constant flux and full of the unprecedented challenges of globalization. With the onset of modern types of fabrics for the garments factory and of technical textiles for functional applications, and with the growing number of invention taking place in the apparel sector, fabric testing processes have undergone tremendous changes and there is required to realize all the procedures before a testing method is involved to investigate the performance of fabrics.

The easy test method to estimate the mercerizing effect.

The latest test method to estimate the mercerizing effect is described bellow


After mercerization, we need to test the effect on textile fibre. We can estimate this different testing and measurement system. The most popular test method is given step by step:


-First, take 10ml of 0.25N Ba(OH)2 in a beaker, then titration with 0.1N HCl and methyl orange as an indicator.


-At the endpoint yellow color solution changes to a pink color solution, and then the titration is completed.


-The measure the amount of HCl used for titration, Let HCl= x ml


-Now take 2gm of mercerized sample


-Then, the sample is immersed into the 30ml of 0.25N Ba (OH)2 solution for 4hoursand then taken out.


-Then, take 10ml of left out Ba (OH)2 solution by pipette in a beaker.


-Now titration with 0.1N HCl and methyl orange as an indicator.


-The measure the amount of HCl used for titration, Let HCl= y ml
