6.2. Analysis of Efficiency by Different Sorts
In this part we have analysed how different sorts run in the
industry will affect the efficiency. Sort (design), will definitely affect the
efficiency of loom. Because for each and every sort, the count of yarn will
vary and number of weft yarn inserted per pick will also vary, which are having
direct influence on the efficiency.
Table 6.4
Sort Vs efficiency
The efficiency of sort 3 has dropped due to multiple weft
insertion, since four weft yarns are inserted at a single pick, a single thread
breakage will lead to lower production. Here a small idle time will reduce the
production to a greater extent. Also there is chance for higher transfer fault.
For sort 3, four looms are assigned for a weaver; this will lead to higher idle
time of the machine, because of higher stoppage and results in lower efficiency
and production.
In sort 2 the efficiency has dropped due to higher weft
breakages. This is because of poor yarn quality.
6.3. Analysis
of Efficiency by Relative Humidity
Here we
have analysed the relative humidity in the industry and how they affect the
efficiency.
Table 6.5
Relative Humidity Vs Efficiency
The above chart shows different relation in parameters,
because the international standards say that the efficiency is higher at 65%
relative humidity. In this case it is upside down. This is because the
standards say we have to maintain a temperature of 27oC but in this
case the industry is running at a temperature of 30.5oC. This should
be controlled to get a higher efficiency.
6.4. Analysis
of Efficiency by Loom Allocation
Here we have analysed the loom allocation of the weavers.
Loom allocation plays an important role in the loom efficiency. We have to be
very careful here because, when more looms are allocated then there will be a problem of efficiency. When less looms are allocated then there will be a problem of wages.
