Analysis on the Defects in Yarn Manufacturing Process

4.1.4 Critical success factors for Blow room

4.1.3 Factors affecting on opening, cleaning and fiber loss
These are the general factors which affect the degree of opening and cleaning

Type of opening device

Speed of opening device

Size of flocks in the feed

Thickness of feed web

Density of feed web

Degree of penetration

Fiber coherence

Fiber alignment

Distance between feed and opening device

Through put speed of materials

Type of grid bar. Grid bar is part of blow room machine which is used for cleaning and opening
purpose.

Air flow through the grid bar

Condition of pre-opening

Amount of material processed

Ambient relative humidity percentage

Ambient temperature
Atmospheric condition of blow room is also important to produce smooth and uniform quality yarn. It also
affects the raw material that why it is very important to maintain ambient temperature and ambient relative
humidity percentage in the blow room throughout the production. Low humidity and slightly higher temperature
are preferred because of the cotton opening temperature. [42]

4.1.4 Critical success factors for Blow room
For achieving yarn quality following are the critical success factor

Cleaning efficiency

Fiber growth
4.1.5 Importance of yarn quality
For producing high quality yarn, it is necessary to follow quality standards according to the customer
needs and Market requirement. High value quality yarn is produced, if high quality yarn with minimum
deviation is used. If fluctuation in yarn quality is high then it will be difficult for end use.
