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.
Yarn Engineering
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.

Reflection and Luster
When light falls on the fiber, part of light is reflected. The luster of a single fiber is determined by the total visual appearance of these reflections from the fiber surface. It is directly proportional to the amount of light reflected by a fiber. Silk fibers has a high luster and cotton has low luster.
Swelling of fibre and Types of swelling
Dimensionally changes due to absorbing water or moisture by any fiber is known as swelling. When fiber absorbs water they change dimensionally. Swelling occurs in transversely (width wise) and axially (Lengthwise). It may be expressed in terms of the increase in diameter, area, length or volume.
