Broadly defined, marketing is a social and managerial process by which individuals and organizations obtain what they need and want through creating and exchanging value with others. In a narrower business context, marketing involves building profitable, value laden exchange relationships with customers. Hence, we define marketing as the process by which companies create value for customers and build strong customer relationships in order to capture value from customers in return.
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tuck stitch is identified by the fact that its head is released as a hump shape immediately the needle loop above it is withdrawn. A knitted loop would be required to be separately withdrawn
Most single-jersey fabric is produced on circular machines whose latch needle cylinder and sinker ring revolve through the stationary knitting cam systems that, together with their yarn feeders, are situated at regular intervals around the circumference of the cylinder. The yarns is supplied from cones, placed either on an integral overhead bobbin stand or on a free-standing creel, through tensioners, stop motionsand guide eyes down to the yarn feeder guides.
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.
