Basic testing of fabric prior to cutting
Fabric is received according to per-forma invoice &
perform inventory. After proper inventory, we are performing minimum testing
standard “Test is method of verifying” which plays important role in apparel
manufacturing. To produce quality-full product we are determined to test the
basic requirement of the fabric in our in house mini lab to secure the product
safety & quality. In this regards, we are testing of fabric e.g Wash test, rubbing
test, shrinkage, Shade blanket. Moreover, we are testing mun- sell to control
the shade of all employee. With the help of this statement, I have
elaborated the topics in details.

Shrinkage procedure
16.0 Purpose: The two yarn combines two yarn in the form of fabric, or fabric, and when the
yarn is attached then gap between two yarn & also some dust . After the washing,
the two yarn's midterm and distorted YARNs disappeared. Because of this,
after the garment disposal, the Measurement can be more or less, so that it does not have to
be such a problem, it is necessary to check the pre-prepared supplemental fabric SHRINKAGE.
16.1 Scope : This process is applicable for woven unit .
16.2 Responsibility:
16.2.0
Quality In-charge is responsible to monitor and to implement the Shrinkage test
process.
16.2.1
QA is assigned to carry out the shrinkage, checking and giving feedback to the
Respective
production unit and management, and maintain the reports.
16.3 Procedure:
Sampling method
Each fabric must have the shrinkage test with one of the rules in each color in the receipt lot.
At least 10% of received quantity of roll should test shrinkage.
In the case of wash Garment (50cm x 50cm) measurements should be marked with
specific measurable templates. Then, according to wash recipe, it will be washed after that
amount of shrinkage should be calculated according to percentage.
In the case of non-wash garments (50cm x 50cm) measurement should be marked with
specific measurable templates. After two minutes of steam with normal condition,
check the Measurement and find out the amount of shrinkage according to the percentage.
Style name, Buyer name, Order & color should be mentioned at the Fabric.
On the basis of shrinkage pattern should be adjusted.

17.3 Procedure : CROCKING TEST
This test
verifies the color bleeding property of garment. The instrument called CROCK
METER. This process done in two types: (1) DRY CROCKING (2) WET CROCKING.
Acceptable standard varies from buyer to buyer but best standard is
DRY 4
WET 3
Procedure
For dry process,
place the swatch of testing material under plate of crock meter. With crock meter cloth, 10 cycle of rubbing will
be done on testing material. Shade effect will come on crock meter cloth, then
measure it with gray scale and allocate the rating. In wet process, everything
remains same except that crock meter cloth is wet with one drop of distil
water.

Color Vision Test / Mansell Test SOP
19.0 Purpose & Scope
The Farnsworth-Mansell Hue Test offers a simple method
for testing color discrimination. It yields data, which can be applied to many
psychological, and shop floor problems in color vision. Its primary uses are
to:
19.0.1 Separate persons
with normal color vision into classes of superior, average and low color
discrimination.
19.0.2 To measure the zones of color confusion of
persons dealing in color shades.
19.1 Responsibilities
19.1.0 QA In-charge is responsible to monitor and to
ensure that all the persons dealing with color shades are tested for color
vision
19.1.1 IQC in-charge is responsible for conducting the
test, communicating the results and maintains the records.

19.2 Procedures
19.2.0 Material:
19.2.0.1 The FM Hue Test includes a total of 93 colors
mounted in plastic caps, housed in four separate cases. Each case consists of
two hinged panels which contain a quarter of the 85 numbered, removable color
caps. (Two caps are repeated and fixed as pilot colors at either end of one
panel in
Each case, making a total of ninety-three caps.)
19.2.0.2 If the caps become severely smudged or
damaged, they should be replaced.
19.2.0.3 With normal usage, it is recommended that the
caps be replaced every four years.
19.2.1
Lighting:
19.2.1 .0Test should be carried out under Day Light
D65 in the light box.
19.2.1.1 Since natural daylight is variable, the
results cannot be expected to be as stable as when the test is given under
standard illumination.
19.2.1.2 Ordinary incandescent room lights should be
switched off or shielded from the test area.
19.3
Testing :
19.3.1 Open one case and arrange the caps in random
order
19.3.2 Instruct the person being tested as below :
19.3.2.3 to arrange the caps in order according to
color and place them so they form a regular color series between the two end
caps (indicate)
19.3.2.4 It should take you about two minutes per
panel. However, accuracy is more important than speed so you will be told when
the two minutes are up but the panel will not be taken away from him/her.
19.3.2.4 To Allow the person as long as necessary to
arrange the caps in an order with which they are satisfied.
19.3.2.5 If two minutes have passed, and the person is
not through, quietly remind them that two minutes are up, and allow more time
to finish the task.
19.3.2.6 Repeat the process for rest 3 cases.
19.3.2.7 Record the time taken to complete the test.
19.3.2.8 Enter the findings into FM Hue Test Scoring
Software.
Testing
receiver:
19.3.4
Only Quality people will receive this
test for all the department like Store, Sample, sewing, cutting, Finishing
& packing etc. .
19.4 Result Analysis
19.4.0 Person with 'normal' color vision can be
classified as follows:
19.4.1 Superior
Discrimination
19.4.2 About 16% of the population (exclusive of color
defectives) has been found to make 0 to 4 transpositions on first test, or
total error score of zero to 16. This is the range of
superior competence for color discrimination.
19.4.3 Average Discrimination
About 68% of the population (exclusive of color
defectives) make a total error score between 20 and 100 on first tests. This is
the range of normal competence for color
Discrimination.
19.4.4 Low Discrimination
19.4.4.0About
16% of the population (exclusive of color defectives has been found to make
total error scores of more than 100. The first retest may show improvement, but
further retests do not materially affect the score. Repeated retests reveal no
region of large maximum or minimum sensitivity as is found in color defective
patterns.
19.4.4.1 Total error scores represent the color
discrimination ability of an individual at a given point in time.
19.4.4.2 It is possible that color discrimination
ability for that individual may improve at a later time as a result of further
training and experience.
19.4.5
Identifying the color defectiveness:
19.4.5.0 The pattern of color defectiveness is
identified using the FM Hue Test by bi-polarity, a clustering of maximum errors
in two regions which are nearly opposite.
19.4.5.1The severity of the defect can be gauged by
the extent of the 'bulge', a severe degree of defect showing clear bipolarity
with high error scores; moderate cases show small 'bulges' and lower total
error scores; mild cases with good color discrimination may show no 'bulge'
19.4.5.2 The position of the mid-point of the errors
in the pattern will identify the type of color defectiveness as below :
Protans : have a mid-point between 62 and 70
Deutans : have a mid-point between 56 and 61
Tritans : have a mid-point between 46 and 52.
19.4.5.3 To handle the shades, the person has to score
minimum Average
Discrimination.
19.4.5.4 If someone scores, poor discrimination, the
test may be re-conducted after six months with proper training.
19.4.5.5 When new QA/QC will be selected at first he/
she will do The munsell test , Any color blind person not allow to work .
19.4.5.6 Every
QA /QC will get Munsell test randomly after one year.
