Procedures

Testing is conducted at all the crucial phases of the production process so that the finest products are manufactured.  In all the procedures, the most modern equipments are used to ensure utmost perfection.

Testing of raw material is very crucial as it is the base of a product. It consists of the fabrics and all garment accessories. Before commencing production, all raw materials whether it is fabric or accessories are tested and ensured whether the same conforms to specifications or not. After ensuring the raw material quality parameters, prototype samples are made and then the overall quality parameters are checked in our in-house lab. If the sample conforms to buyers specifications then again samples are prepared and tested from commercial certified labs for buyer 's approval. After approval from buyer actual production process starts.

Beside production sample testing, sampling samples are also tested. During the sampling process any fabric swatch recommended from buyers end and any other trims or accessories to be used are analysed under close investigation to face any unforeseen problems.

 

Details of Tests

All tests has been classified into 5 major groups such as composition and analytical tests, construction analysis, colourfastness tests, strength or durability tests and dimensional stability cum appearance tests.

Composition and analytical tests

Composition means fibre content of any fabric, type of fibres being used and their quantitative share in the fabric.

Formaldehyde free test: any fabric or accessories meant for apparel purpose should be free from formaldehyde or should be under certain limit. This formaldehyde is found to be highly skin allergic. So there should be no formaldehyde in the apparel from consumer's point of view.

Anti rust test: Any metallic component used for garment making should be rust proof. Otherwise during the useful life of the garment the component will rust which will deteriorate the aesthetic appeal of the garment.

Nickel free test: nickel which is widely used as a coating for rustproof has been found to be highly toxic when comes in contact with skin. So different buyers recommend not using any metallic component which has nickel coating.

pH value : washing process consists of using alkali. So after rinsing there should be no residual alkali in the fabric. Moreover our skin is friendly to slightly acidic medium. Higher level of acid or alkali in the fabric makes skin irritation. So the pH value of any clothing textile should be within the recommended limit.

Construction analysis

It is very important to know the construction parameters of the product to ensure whether it is within recommended level or not.

Yarn count: to check whether the yarn fineness of the fabric conforms to specifications or not.

Fabric weight: to check whether the fabric weight per unit area conforms to specifications or not.

Construction: to check whether the fabric has required number of yarns per unit length or not.

Type of weave: to analyse the construction design of the fabric.

Skewness and bowing: the yarns running along the width wise direction of fabric are supposed to be perpendicular to the length of the fabric. But in certain cases due to processing defect these yarns become angular / oblique called skewing or may become the arc of a bow called bowing. These deteriorate the aesthetic appeal of the garments especially in case of check and stripe effects.

Type of yarn /whether carded or combed: to determine the quality characteristics of threads used to make the fabric.
   
Colourfastness test This is one of the most important tests carried out to determine whether the colour property of garment will be able to resist the various external forces which the garment may face during its usage.
Strength / Durability tests Consumer may be interested to know that how much strong or durable the garment will be. In order to evaluate it there are various tests such as tensile strength, tearing strength, seam strength and snap strength etc. Sometimes it becomes important to know the elasticity of the elastic material.
Dimensional stability/appearance tests

These category of tests include whether the size, shape and look of the garment will change or not after cleaning process of the garment which the consumers have to do several times.
