Calculation of
finished fabric requirement:
We have to produce 130560/12 = 10880 dozen of T-Shirt
So, we need 10880*2.30 = 25024 kg knitted fabric of 140 GSM
Considering the pattern allowance 4% (Marker efficiency and
fabric inevitable rejection)
So, total finished fabric we have to produce is
25024+25024*4% = 26025 kg (rounded)
Value of finished
fabric:
Selling value of those fabrics to garmenting unit is 6.0
USD/ kg
So, Total finished fabric value = 156150 USD
Calculation of grey
fabric requirement:
Let say, process loss in coloration (dyeing finishing) is
10%
So, we have to produce 26025+26025*10% kg = 28628 kg of grey
fabric (rounded)
Calculation of yarn
requirements:
Let say, knitting process loss is 0.5 %
So, yarn requirement is 28628+28628*0.5% kg = 28772 kg of
yarn
Non woven Fabric
Consumption of yarn:
Considering the 140 GSM fabric we have to choose 32’s combed
cotton yarn which market price is 3.1 USD per Kg(in that particular time), Then
total cost of yarn is 28772*3.1 = 89194 USD
Calculation of fiber
requirement:
Let say, we get 73 kg combed cotton yarn from 100 kg of
cotton fiber.
So, to make 28727 kg of combed cotton yarn we need
(100*28727)/73 kg fiber
=
39353 kg cotton fiber.
Note:
We can get 72 kg to 75 kg combed cotton yarn from 100 kg of
cotton fiber, depending upon the fiber quality.
We can get 86 kg to 88 kg Carded cotton yarn from 100 kg of
cotton fiber, depending upon the fiber quality.
Noil extraction in combing process is 13% to 18% depending
upon the quality of fiber and yarn quality requirement.
Value of cotton
fiber:
Let say, cotton fiber price of that particular moment (when
order is executing) is 78 US cents per pound
So, cost of cotton fiber is (139353*0.78)/0.4536 USD =67671.0
USD
1 Pound is equal to 453.6 gram
Value addition in fiber to yarn form =
{(89194-67671)*100}/67671 % = 31.80 %
Value addition in yarn to finish fabric form = {(156150-89194)*100}/89194

In electrical system require annual analysis of transformer oil testing based on the aspect of Color, Dielectric breakdown voltage, Dissolved metals, Flash point, fire point, Interfacial tension, Liquid power factor, Oxidation inhibitor content, Polychlorinated biphenyls content, Visual examination and this type of maintenance procedure which help us to ensure that they are operating safely and with an most advantageous effectiveness. For the time being, maintaining transformer oil testing too crucial to pass up or diminish the risk factor. This aspect obviously plays an important role to eliminate the fire possibility at Auto Accessories Limited. On the other hand on time electrical maintenance increases system survival and ensure trouble free services. The insulation oil of voltage- and current-transformers fulfills the purpose of insulating as well as cooling. Thus, the dielectric quality of transformer oil is a matter of secure operation of a transformer. As transformer oil deteriorates through aging and moisture ingress, transformer oil should, depending on economics, transformer duty and other factors, be tested annually. Voltage breakdown during oil test Transformer oil testing sequences and procedures are defined by various international standards. Power utility companies have a vested interest in periodic oil testing since transformers represent a large proportion of their total assets. Through such testing, transformers’ life can be substantially increased, thus delaying new investment of replacement transformer assets. aaaa
SCOPE:
Applies to own transformer (Converting high voltage to low tension side voltage) situated at Auto Accessories Ltd. sub-station room which actually the key of distribution in all Electrical Panel Board / distribution board at Auto Accessories Ltd.
DEFINITIONS:
The fault free operation of power transformers is a factor of major economic importance and safety in power supply utilities and industrial consumers of electricity. In the current economic climate, Industries/Supply Utilities tighten their control on capital spending and make cutbacks in maintenance; an increased awareness is placed on the reliability of the existing electric power supply. Down time is at a premium. Often, the loading is increase on present units, as this will defer purchasing additional plant capacity. Thus the stress on the transformer increases. The net total effect of the thermal, electrical and mechanical stress brought on by increased service needs to be monitored to ensure reliability. Regular sampling and testing of insulation oil taken from transformers is a valuable technique in a preventative maintenance program. If a proactive approach is adopted based on the condition of the transformer oil, the life of the transformer can be extended.
RESPONSIBILITY:
Asst. Manager, Jr. Manager, Sr. Supervisor, Supervisor of Maintenance Department and the analyzing personnel from the transformer analyzing
PROCEDURE:
Preventive Maintenance:Maintenance manager Make a defensive Maintenance Record due to this aspect.
Maintenance record (shown as follows) has exercised to annual basis of frequency (Frequency of inspection: Annually)
5.2 Wellbeing of session:
Maintenance personnel should be used to the followings when transformer oil analysis conducted by the third party:
Know how to treat victims of electrification during XF5 oil testing period.
Before working on transformer oil testing ensures that REB power (11KVA) is shutting down.
Wearing all type of safety appliance (which needed in this perspective) and factory personnel must ensures the appearance of safety. In case of emergency, if work is necessary on Power-ON-lines (i.e. Hot line)
While electrical work is going on post a sign stating “do not switch on power” as an instance: LOTO mechanism.
Ensuring the calibrated testing equipment of oil analysis to the factory representative.
Factory representative must ensure the adequate manpower in sense of helping hand during the data acquisition process.
Don’t make any unusual situation during testing period.
Maintenance personnel must wear the electrical safety shoes and electrical graded hand gloves to
conduct as a helping hand. Core Scheme of testing:
The transformer oil is filled in the vessel of the testing device. Two standard-compliant test electrodes with a typical clearance of 2.5 mm are surrounded by the dielectric oil.
A test voltage is applied to the electrodes and is continuously increased up to the breakdown voltage with a constant, standard-compliant slew rate of e.g. 2 kV/s.
At a certain voltage level breakdown occurs in an electric arc, leading to a collapse of the test voltage.
An instant after ignition of the arc, the test voltage is switched off automatically by the testing device. Ultra fast switch off is highly desirable, as the carbonisation due to the electric arc must be limited to keep the additional pollution as low as possible.
The transformer oil testing device measures and reports the root mean square value of the breakdown voltage. WE sale Manufacturing Accounting Software
After the transformer oil test is completed, the insulation oil is stirred automatically and the test sequence is performed repeatedly. (Typically 5 Repetitions, depending on the standar Conclusion: The lower the resulting breakdown voltage, the poorer the quality of the transformer oil!
When cotton is dyed in gray state it is important to evaluate the wetting property of an auxiliary used as dispersing agent or colloid protective in order to determine if the product can be used without the addition of another wetting product. This test will show the wetting and penetration properties of the DPA when dyeing gray cotton. We sale Asset Management Group Wise Allotment Software

The philosophy of “Digital Bangladesh” comprises ensuring people’s democracy and rights, transparency, accountability, establishing justice and ensuring delivery of government services in each door through maximum use of technology-with the ultimate goal to improve the daily lifestyle of general people. Government’s “Digital Bangladesh” includes all classes of people and does not discriminate people in terms of technology. Hence, government have emphasized on the four elements of “Digital Bangladesh Vision” which are human resource development, people involvement, civil services and use of information technology in business.
The government has to realize that Digital Bangladesh is a vision that can be turned into reality only through joint efforts by all sectors — if they think that it is something that the government will deliver to the people on their own, they will start from the wrong premise and Digital Bangladesh may always remain nothing more than a politician’s game of words and hollow promises.
