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.
