Knitting Faults in fabric : Weft fabric faults, Causes and Remedies 1. Hole Mark   Causes: ❶ Holes are the results of yarn breakage or yarn cracks. ❷  During loop formation the yarn breaks in the rejoin of the needle hook. ❸  If the yarn count is not correct on regarding structure, gauge, course and density. ❹  Badly […]

When the needle is raised sufficiently high by the camming action to obtain the yarn in the hooked portion of the needle and the old loop is below the latch [i.e, the old loop is cleared], a knit stitch will be formed as the needle descends.

A float stitch or welt stitch is composed of a held loop, one or more float loops and knitted loops.It is produced when a needle (M) holding its old loop fails to receive the new yarn that passes, as a float loop to the back of the needle. The float stitch shows the missed yarn floating freely on the reverse side of the held loop.

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tuck stitch is identified by the fact that its head is released as a hump shape immediately the needle loop above it is withdrawn. A knitted loop would be required to be separately withdrawn

The sinker is the second primary knitting element (the needle being the first).It is a thin metal plate with an individual or a collective action operating approximately at right angles from the hook side of the needle bed, between adjacent needles.

Primary knitting elements:Three primary knitting elements: Needle: Latch needle, Spring bearded needle & Compound needle. Cam: Knit cam, Tuck Cam, Missed cam Sinker: Holding down sinker, Knocking over and loop forming sinker Main parts and their functions of latch needle The hook: Grasping a new yarn in the process of knitting i.e. the hook which draws and retain the new loop. The latch: Freely rotating around the axle and tightly closing the hook owing to the spoon located at the end of the latch.

Knitting is a technique to turn thread or yarn into a piece of cloth. Knitted fabric consists of horizontal parallel courses of yarn which is different from woven cloth. The courses of threads or yarn are joined to each other by interlocking loops in which a short loop of one course of yarn or thread is wrapped over the another course.
