Any small entanglement of textile fibers that can not be unraveled, formed during carding or ginning.
Classification of Neps
For cotton fiber; there are five types of Neps. These are –
Process Neps: Commonly produced by faulty carding or up to spinning yarn.
Mixed Neps: Fibres tangle around a foreign materials. For instance – Grit.
Immature Neps: Generally form by processing immature fibre.
Homogeneous Dead Neps: A tangle of nearly all dead fibres.
Fuzz Neps: A fault of short fuzz fibers .
Count of Neps
Nep count is the no. of neps per 100 square inches of card web forming ( a standerd hank of sliver of 12 NE on a 40 inch wide card).
How To Measure the Count of Neps?
At first a web is collected from the card placed on a 10 inch × 10 inch black board. Then the neps are counted and the no. of neps found is corrected fro any difference in hank or card width.
Mathematically, Nep Count, n = m × 100 [ m = no. of neps per inch square card web].
