How do you increase production on a spinning mill?
Improving Productivity of Spinning Mill
- Maintenance management practices.
- Process parameters adjustment.
- Fine-tuning of all process machinery.
- Training and development of Operators.
- Quality management.
- KPIs for increasing accountability.
- Prodn: Ne 23s to 30 days/month (MT)
What is HOK in spinning mills?
Data is analysed based on the South India Textile and Research Association standard for spinning mills. According to the institute, labour productivity indices are the number of operative hours required to produce 100 kgs of yarn (HOK), operatives per 1000 spindles (OHS), and composite productivity index (CPI).
How do you assess a spinning mills productivity?
It is calculated by dividing the total spindle hours worked per day by the installed spindles. The spindle utilisation is also expressed as percentage. MPI : A combined measure of production per spindle and spindle utilisation.
What does a spinning mill do?
Spinning. A spinning mill opened raw cotton bales and cleaned the cotton in the blowing room. The cotton staples are carded into lap and straightened and drawn into roving which is spun using either a mule or ring frame. The yarn can be doubled and processed into thread, or prepared for weaving.
When twist is increased in a spun yarn its strength?
Since the filaments are of variable strength, so the primary function of twist is to provide support to weaker filaments thus resulting in an increase in the yarn strength. The influence of increasing twist on a continuous filament yarn is shown in Figure-2.
How spinning of fibres increases the strength of yarn?
These bonds produce strong inter-chain forces in the fiber, which increase its tensile strength. The polymer chains within the fibers also have a large degree of orientation, which increases strength. The fibers are first air dried, then cooled further in a liquid bath.
How is HOK calculated in spinning mills?
Manpower requirement calculation – assuming HOK 8 ( 8 operating manhour to produce 100 Kg yarn.), Monthly production 3000 Tons , 8 hours shift for 26 days per worker in a month. Total HOK required – 3000 x 1000/100 x 8 = 240,000. Manpower requirement – 240,000/8/26 = 1153.
How does spinning help the textile industry?
One important step is spinning the yarn. Spinning is the process of taking textile fibers and filaments and making them into yarn. For thousands of years, people spun natural fibers into yarn by hand. Converting fibers and the substances that form synthetic filaments into yarn involves different methods of spinning.
How does a spinning machine work?
This is a machine to whirl the spindle by turning a wheel. When the spinning wheel is employed, the cleaned wool or cotton is first carded, then twisted loosely, and finally spun into yarn. These short cardings are twisted on the spinning wheel, into a loose thread, or roving, about the size of a candlewick.
Why is the spinning process important?
Spinning is the crucial and significant stage of processing textile products. Before spinning of cotton yarn, the obtained plant fibre has to go through several procedures to remove impurities such as blending, opening, cleaning, drawing to obtain a final yarn of desired thickness.
How is the success of a spinning mill determined?
Detailed analysis of spinning mill setup, cost of production, investments, return on investment, profit calculation, ideal production output calculation etc. The success of a spinning mill depends on the loan, personal investment, interest rates, raw material cost, count and category of mill production, selling price, daily expenses and revenue.
Is there any way to save energy in spinning mills?
Energy is one of the main cost factors in a spinning industry. There are various energy saving methods that exist in every spinning mills. Spinning mills in Bangladesh are facing greater challenges day by day. Rising power tariff (Gas & Electricity) makes industries more vulnerable.
Why was the spinning process important to the Industrial Revolution?
Industrial revolution bought dynamic changes in our daily lives and textile manufacturing process is no more an exception. Spinning mills are significant for textile industries as they transfigure fibre into yarn and yarn into fabric.
Why is cone winding important to the spinning process?
Cone winding is just a simple packaging process functioning as a link between last stages of yarn manufacturing and initial stages of fabric manufacturing process. It is important to utilize the winding devices properly to avoid the loss of spinning mills as well as consumers.
