Lap preparation is the process to prepare for combing process by making flat laps with combining multiple threads of carded slivers. It is the important step in the combing process, which influences the quality of the combed sliver.
Basic Concept of Combing Process | Types of Comber Machine
Combing is the process that removes the final proportion of short fibers, neps and others impurities such as vegetable matter and seed coat fragments in cotton that has already been carded. Combed yarns are superior in quality when compared to carded yarn as they are generally finer, stronger, smoother and more uniform due to the removal of short fibers and the alignment of fibers.
Different Action of Combing Machine
Noil consists of shorter fibers and neps. The amount of noil removed in the combing process may be varied to suit the circumstances and is usually expressed in percentage based on the original weight of laps fed into the machine.

Name of Expt.: Determination Of Relative Humidity By Wet And Dry Bulb Hygrometer. Objects : To find out the temperature and relative humidity of lab room Theory: Relative humidity is the ratio of actual vapour pressure to the saturated vapour pressure of the same temperature. Expressed as percentage. Relative humidity = actual vapour pressure/standard vapour […]
Introduction to Desizing of Warp Yarns
Introduction to Sizing Introduction to Desizing of Warp Yarns Desizing : Desizing is the process in which the size applied to the warp yarn before weaving is removed to facilitate the penetration of dyes and chemicals in the subsequent wet processing operations. In the process of desizing, not only sizing agents, but also some natural […]
