Padma Poly Cotton Knit Fabrics Ltd. is one of the 100% export oriented industry in Bangladesh. By means of the practical knowledge it’s possible to apply the theoretical knowledge in the practical field. For any technical education practical experience is almost equally important in association with the theoretical knowledge.

The industrial attachment is the process which builds understanding skills and attitude of the performer, which improves his knowledge in boosting productivity and services. University education provides us vast theoretical knowledge as well as more practical attachment, despite all these industrial attachment help us to be familiar with the technical support of modern machinery, skill ness about various operation stages.

It also provides us sufficient practical knowledge about production management, productivity evaluation, work study, efficiency, industrial management, production planning and control, production cost analysis, inventory management, purchasing, utility and maintenance of machinery and their operation techniques etc. the above mentioned can not e achieved successful by means of theoretical knowledge only. This is why it should be accomplished with practical knowledge in which it is based on industrial attachment makes us reliable to accustomed with the industrial atmosphere & improve courage & inspiration to take self responsibility.

I have prepared this report as required in completion of my attachment course in regarding guideline given by the university authority which will lead to a strong guideline and milestone for our future carrier.

Lab – Dip Procedure:

Lab – dip:

Lab – dip is a process by which buyers supplied swatch is matched with the varying dyes percentage in the laboratory with or without help of DATA COLOR.

Lab – dip plays an important role in shade matching & detaching the characteristics of the dyes and chemicals are to be used in the laree scale of production so this is an important task before bulk production.

In Padma Poly Cotton Knit Fabrics Ltd. also a well established laboratory with modern machineries and equipments. First of all the dye % of the Standard sample is measured by the data color and computer color matching system. Then by taking that recipe lab In – Charge produces lab trail and match with the standard according to buyer requirements after approving the sample, this sample is sent to bulk production with recipe

Washing for Colored fabrics:

Colored fabrics to be washed ate loaded in the m/c.

Required amount of water is taken.

PCLF (Detergents) added and washing continued at 800C for 20 min.

Cold washing.

Scouring & Bleaching:

Fabric to be scoured is loaded in the machine.

Required amount of water is loaded.

Detergence / washing agent is added (From recipe).

Steam pipes are on and scouting agent (Caustic soda / soda ash) added when the temperature reaches at 500C.

When the temperature reaches at 600C then stabilizer added.

Then H202 is added.

Temperature is then raised to 950C and the process then carried out for 60 – 90 min depending on the requirement.

Then the liquors are the drained.

Then Cold wash at 300C – 400C, Hot wash at 800C – 950C and Acid wash at 400C – 500C, (600C) is done.

After Scouring:

Added acid + Peroxide Killer

PH 4.5

Temperature 55 600C

Run Time 10 – 20 min

Then added Enzyme.

Dyeing :

After acid wash all liquors are drained out.

Required amount of water is taken.

Then leveling agent, anti-creasing, de-foaming agents is added according to the requirement.

Then the temp is raised up to mark and after 10 – 15 min dyes are added.

Salts + Soda are added after another 30 min.

Then the temperature is raised slowly up to the mark.

The process is carried of and samples are taken after every 10 – 20 min to match with the target shade. It will be continue until shade matching.

If the sample is matched then the liquors drained out Cold wash at 400C – 500C, Hot wash at 700C – 800C, Acid wash at 400C – 500C is done.

Then softner is added at 450C for 20 – 30 min.

Fixer is applied for deep shade only before adding softner.

Re – dyeing:

When shade is not matched then fabric is treated again in dyeing m/c for shade matching is known as Re – dyeing.

Generally re – dyeing is done if the shade is deeper or lighter then target shade, If may occur when the fabrics absorb one or two color more or less.

Re – dyeing process is described below:

Drain the left off solution,

Hot wash at 700C – 800C.

Acid wash at 400C – 500C (400C = Light shade, 500C= Deep shade)

Soda washes at 900C – 1000C. For 60 min to reduce the depth of shade.

Acid wash at 600C.

Added to required dyestuffs.

Salt added.

Other operations are same as pervious described dyeing operations.

Production parameters in knitting section:

The main Parameter controlled in knitting section are stitch are length, GSM, Fabric diameter etc.

Different parameters in knitting machine:

Machine pitch (t):

Is defined as the distance between the centers of two adjacent needle of the same needle row indicated in mm.

Pitch= 25.4 mm/ gauge (E).

Machine gauge (E):Machine gauge denotes the number of needles per inch,Arranged on the needle carrier and based on the nominal machine diameter.

Gauge (E) = 25.4 mm/Pitch

Loops: It is a basic unit consisting of a loop of yarn meshed at its base with previously basic unit.

Stitch: The smallest dimensionally stable unit of all knitted fabrics is the stitch, It consist of a yarn loop which is held together by being intermeshed with another stitch or other loops.

Stitch is composed by:-


Side limbs or shanks



Stitch length: Stitch length is a length of cam which includes the needle loop & half the sinker loop on either side of it. Generally the larger the stitch length, the more extensible & the poorer the cover, capacity & bursting strength.

Basic knitting element:





Function of needles: Needle is raised to clear the old loop from the hook & receive the new loop above it on the needle steam.

Types of needles: In general there are three types of needles.

Bearded needle

Latch needle

Compound needle


Function of CAM: The functions of CAM are as follows:

To produce motion to needles

To drive the needles.

Formation of loops.


Function of sinker:

It may one or
