Management and it’s Functions

Management involves four basic activities—planning and decision making, organizing, leading, and controlling. Although there is a basic logic for describing these activities in this sequence (as indicated by the solid arrows), most managers engage in more than one activity at a time and often move back and forth between the activities in unpredictable ways (as shown by the dotted arrows).

Index of Irregularity

The ratio between the actual irregularity present in the material and the calculated limit irregularity is called index of irregularity. It is denoted by I. Accordingly the best yarn have a value of I = 1. Thus, the higher value of I indicate that the yarn is more irregular. On the other hand, the CV of the most regular/uniform strand of material in which the fiber ends are laid in a random order in the sliver, roving, or yarn is called limit irregularity.

Tuck Stitch and it’s Formation Process

A tuck stitch is composed of a held loop, one or more tuck loops and knitted loops. It is produced when a needle holding its loop (T) also receives the new loop, which becomes a tuck loop because it is not intermeshed through the old loop. The tuck loop thus assumes an inverted V or U-shaped configuration. The head of the tuck is visible on the reverse of the stitch.The side limbs of tuck loops thus tend to show through onto the face between adjacent wales. Tuck stitch structures show a faint diagonal line effect on their surface. In analysis, a tuck stitch is identified by the fact that its head is released as a hump shape immediately the needle loop above it is withdrawn. A knitted loop would be required to be separately withdrawn
