Methods:
This factory use to produce carpet by the loom. The producer
fulfill their work, they are also modified the the hand loom. But the process
of carpet produce is the same in the shuttle loom.
This loom uses one shuttle to produce one color of carpet.
To produce different design and color use to multi shuttle. This loom treadle
levers are control by the leg. This loom use maximum 10 heald frame. This loom
use threads (TC) yarn to work heald eye.
This loom has big flinch to protect the warp thread
selvedge. Also use long ring pipe to produce loop carpet design. After produce
loop formation design then cut the loop head to produce a new design (terry
towel). This loom has no picking stick
or rod because the workers are control pick by hand.
Weaving Related Defects/Problems
Mill Bars-
Definition and Causes:
A slight variation in the speed of the shuttles or other
devices that carry the yarns and their traverse action sometimes create weft
yarns (across the width of the fabric) of different lengths and tensions.
This is commonly referred to as Mill Bars.
During the dyeing process the uptake of dye in these areas
will be different and causes lighter or darker shade bands to appear on the
fabric.
Preventive Suggestions:
Monitoring the speed and controlling the tension of the weft
yarns are essential and an important part of the weaving process.
Corrective Measures:
For this problem no corrective measures are available.
Warp Lines-
Definition and Causes:
During the Warping process yarns are wound on beams at
regular and measured intervals and pre-determined spaces.
A slight discrepancy in these pre-set spaces causes vertical
lines to appear along the length of the fabric and parallel to the selvedges.
Preventive Suggestions:
Correct and precise warping is always a critical and
important part of the weaving process and needs to be closely monitored.
Corrective Measures:
For this problem no corrective measures are available.
Holes-
Definition and Causes:
Most holes which occur during the knitting process are a
result of what is known as “Drop stitch”.
This Drop stitch is normally caused by the sudden
dis-engagement of the needle at the knitting zone. The causes are:
Yarn’s dry condition where in certain cases it can produce
static charges causing the yarn to be repelled and thus miss the needle,
The malfunction of the Positive feed system which supplies
the yarn to the knitting elements at a steady and controlled rate, and
Excessive yarn slubs and thick and thin places.
Preventive Suggestions:
Regular maintenance and upkeep of the machine are essential.
The condition of yarns also needs to be evaluated.
Corrective Measures:
For this problem there are no corrective measures are available

Loom Factory Visit
Then we knew about all to our honorable instructor. She has given us some tips for making our project work theoretically. Then we started our work by internet. But some days later our honorable instructor went to Mirpur 11 at Behari Polly with our students. She searched also about our project Carpet manufacturing there. And finally she was success and she informed us that night. According to her address we went there and got some Carpet manufacturers at Millat camp in Mirpur11. The Biahari people were, made carpet in Bangladesh from 1948 after Second World War. There have 4 looms of carpet. They made carpet in small amounts. Fardin carpet was one of the carpet exporters in Bangladesh. But now they are not involved with carpet exporting due to many reasons. Read also Sample Rapier Loom

Following so a strong family tradition related to the
textile industry the “Agence CHOLLETON” started to operate 25 years
ago and was quickly known and recognized as a specialist for quality axminster
contract carpets and jacquard wilton woven bespoke carpeting plain or
patterned, available from stock ranges or custom made, as for stairs carpet
runners and bespoke hand tufted rugs.
As you may see from our project list our references are
various and prestigious in France and Europe as in many countries worldwide
especially into the Middle East and Africa. Agence CHOLLETON has been involved
over the last 25 years into major export projects for contract carpeting all
around the world, with some of the best contract carpets manufacturers such as
Trafford Carpets or Couristan carpets.
We also known about “Society
Handicrafts” from Bihar peoples. Bihari
peoples have given us location of Society Handicrafts. But that was not right
location. We went first at Saver bus stand and searched in many places but not
found the address of Society Handicrafts. We searched more than 05 hours in
different places of Savar. At the last moment of the day we found an address
from a man he told us in Nama Genda there have a people who make some carpet
and gave them products in “Aarong”. His name is Ali Akbor. Then we went before
evening at Nama Genda in Savar. Finally we found his factory and visit factory
more than 2 hrs with Ali Akbor. He is really an energetic and skilled man. He told us his history of regarding
carpet. We visited and known about
carpet manufacturing, raw materials, how to store carpet, how to receive an order
etc system.

Industrial Case Study
It was Saturday afternoon & like every other day we were working in our desk. We had a meeting with Kajal sir & designing team of. We had known that “Victor Rawlinson” the owner of worlds one of the most renowned importer ‘’David Howard’’, was going to visit auto group for the last time because he was retiring.
We decided
to change the whole interior of the building. We decided to make a portrait of
victor Rawlinson & change our window display. We also made a plan of
designing the banner & changing the beam decoration. We were divided into
two groups. We were two members in each group. After two days we got our budget
to buy all of our equipment. We collected everything from different places.it
was not an easy task.
We started our work. We, two members were working for the portrait & two for the window display. We started our portrait from 2:00 p.m. & it was completed at 10:00 p.m. Sometimes we worked together for window display. R&D department head helped us. We selected the street theme for our window display. We created an environment of U.K. Graffiti Street. We used some props like skate board, helmet, accessories etc. to create proper environment for the display.
The compressor itself should always be under the
supervision of a competent person who should be responsible for ensuring that
the guards for the V-belt and pulley drive are in place and also for the
regular inspection of the necessary hoses and couplings. A check must also be
made that the oil feed to the airline is properly topped up. Compressors
required adequate ventilation and special provision therefore needs to be made
when compressors have to be sited in confined areas.
Air receivers must be marked with their safe working
pressure and distinguishing number; they must also be titled with a safety
valve, pressure gauge, drain cock and manhole. Air receivers must be cleaned
and thoroughly examined at least every 26 months.
Hoses;
All compressed air hoses must be the right size for
the tool; if the bore is too small, insufficient power will be supplied. The
length of hose should be kept as short as possible: it should be kept free from
corrosive materials and leaks and protected from damage by passing traffic.
Hoses should conform to OSHA standards.
If work is to be undertaken at some distance from the Diesel Air Compressor, the safest method of ensuring efficiency is to use large bore pipe most of the way, then to fit a shut-off valve where the normal bore feed to the tool begins.
All connections of Diesel Air Compressor must be properly clamped loose connections can blow off causing the hose to whip back and cause injury. It is also dangerous to over tighten the connections because this can result in the hose being cut causing leakage and loss of power. Safety devices which restrain connectors in the event of a blow-off are available; alternatively, double lock couplers may be used.

with similar redox potential , provides a lower pH than ordinary sodium
sulphur.
This inferior alkalinity offers the following advantages:
Smaller degradation of sensitive fibers in goods containing weaker fibres (half wool, rayon
acetate, etc.).
Less cellulosic fibres swelling and consequently, easy dye penetration in machines with bath
circulation through the material.
Another advantage of the in front of the sodium sulphur it is the easy
removal of the remaining sulphur by means of a single cold rinsing after the dye.
is odourless and it doesn’t produce any scent, avoiding the troubles
working with conventional sulphur reducers.
Reduction state can be checked on the way, dropping the dye bath on a filter paper, the stain
should not present insoluble particles and the extended aureole , it should be coloured the same all
over from the central part where it has thrown the drop.

Bias Line-Definition and Causes
This condition which can easily be seen on the greige goods
also predominantly occurs in the single Jersey structures and, if finished
incorrectly, can cause angular hem line distortion.
The main cause for this condition is knitting machine’s
feeder numbers. As a general rule increasing the number of feeders increases
the Bias angle.
With the increase in demand for finer and lighter weight
fabrics and also increase in the number of feeders in knitting machines this problem
is becoming more evident.
Due to the nature of weft circular knitting process certain
Bias is inevitable and most fabric producers and garment manufacturers have
come to learn to effectively manage this problem.
With new and advanced knitting machines, in order to
increase the rate of production, the number of feeders has been increased, thus
accentuating this angular distortion.
Preventive Suggestions
To reduce the angular distortion and have a manageable
measure of Bias, the simple remedy is to reduce the number of feeders (lower
than 92, preferably down to 60). This is done by disengaging some of the
knitting zone’s needles. Correct finishing of the fabric as well as an
adjustment in the markers to compensate for the excessive Bias are other important
steps that need to be taken.
Corrective Measures
During the dyeing process, due to exposure to water and
temperature and the subsequent shrinkage that takes place, the fabric will
obtain a dimensionally relaxed state including its natural Bias.This is the exact state in which the fabric needs to be
dried at.Any attempt to correct the natural Bias (even severe Bias),
will create an unnatural condition.
The garment manufacturers can now use this fabric provided
that they make the necessary adjustments in their markers to compensate for the
Bias.
We know carpet is a colorful
thing. It is mainly used for floor coverings. It is increases the beauty of
home and official also.

To remove impurities is from carpet.
To increase lusture of carpet.
To make soft handle.
Procedure:
First we haveto lay the carpet in the field.
Then it is have to fall water on the surface of carpet.
Then wash the carpet by brush.
Then have to dry the carpet by sunlight.
Dyeing Related Defects/Problems
Uneven Appearance and Blotchiness-
Definition and Causes:
There are many factors that could cause these conditions.
The following are the most common causes:
uneven exhaustion of dyes (disperse and acid dyes)
uneven absorption of dyes
(reactive and direct dyes)
incompatibility of dyes in the color formula
incorrect or incomplete preparation of the greige goods
prior to dyeing
left-over and un-removed preparation chemicals prior to
dyeing (Hydrogen Peroxide)
insufficient and improper use of Retarders/Leveling
chemicals (in direct dyes)
incorrect fabric dwell time in the dye machine
high dye bath water hardness
application of fixing chemicals in un-clean dye bath water
the use of high energy disperse dyes at low temperatures etc.
Preventive Suggestions:
Due to the complexity of the dyeing process, every technical
aspect of dyes, chemicals and type of machineries, must be studied and taken in
to consideration before any attempt is made to select a procedure to dye a
fabric.
Corrective Measures:
Generally, and in less severe cases, removal and stripping
the original color and re-dyeing the fabric may correct the problem. Although,
total removal of the original color may weaken the fabric and thus special care
is required.
In more severe cases, over-dyeing in to a darker shade or
black may be the only solution.
Non-Union Dyeing (Cross-Dyeing)-
Definition and Causes:
This is a common problem with fabrics that are made with
blended yarns where one component of the yarn appears to be of a different shade.
Preventive Suggestions:
In order to get an even and uniform (union) color, both
fibers need to be dyed to the same color according to their percentage content.
This could be done by dyeing one component first followed by
the other fiber. This is known as “2 bath dyeing “
The other way would be to dye both components
simultaneously, which is referred to as
“1 bath dyeing”. This process is difficult and can not be
performed for certain colors.
In either case care must be taken to ensure that complete dye
uniformity is achieved.
Corrective Measures:
In most cases the non-union color can be corrected by making
an appropriate dye addition.
Winch Dyeing Machine : It is, however, very important to make sure any softeners or other finishing chemicals that are on the fabric are thoroughly removed before the dye addition is made.
