Term of knitting

makes the fabric more compact and offers better dimensional stability and shape retention Sometimes it also improves the bulk of the fabric (cardıgan is an example), 1e thickness of the fabric Meneses Tuck stitch structure is generally less extensible and porous in nature The tuck stitch can also be used for one or more of the followings:
Patterning and fancy effects by using colored yams Making heavier fabric Introducing special type of yam (flexible, thick, etc.) Reducing laddering tendency in sıngle knit structures Marking the panels of garments for sıze or the cutting lines of armhole, neck, etc Floating and float loop (or missing and miss loop):

If during rising, needle reaches to such a height that neither the old loop is cleared nor the needle hook Can catch new yarn during downward movement, then the old loop Is not cast-off but retained in the hook as well as no new loop is formed.
This situation is called floating The yarn passes under the noodle and remains straight between the neighboring loops The straight yarn connecting two nearest loops knitted from is called float or miss loop.

Term of knitting


The missed yarn floats freely on the reverse side of the held loop which is the technical back of the single jersey structures but is the middle of the rib and interlock structures The held loop is extended in wale dırection until a knitted loop is formed Structures incorporating float stitches tend to exhibit faint horizontal lines, they are narrower because the wales are drawn closer together
Float stitches also reduce the widthwise plasticity and improves the dimensional stability Continuous float for a maximum of SIx adjacent needles is generally practiced Float stitch provides a convenient way of hiding colored yarns at the back of the fabric when they do not knit at the face Combination of knitted and short float produces a fabric that does not ravel from the edge and for this reason they are used in welts of stockings


Fabrics made with float stitches are as follows: Thinner and lighter than tuck stitched or normally knitted one Narrower and less extensible Flimsy or less rigid


The Course


A course is a horizontal row of loops produced by all the adjacent needles during the same knitting level It is equivalent to a pick or weft yarn in a woven fabric It is expressed as courses per inch (epi) or courses per centimeter (c p.cm) Fabric is produced by makıng courses in consecutive order Number of loops in a course is equal to the number of needles in operation 9.3.3

The wale

A wale is a vertical column of loops made by the same needle in successive knitting levels. It s equivalent to warp end in a woven fabric. It is expressed as wales per inch (wpi) or wales per centimeter (wp cm ) The total number of wales in a fabric is obtained from the total number of needles in operation


LOOP LENGTH AND COURSE LENGTH


Length of yarn contained in a loop is called loop length or stitch length Course length is the length of yarn required in the production of a course Course length is obtained by multiplying the stitch length with the number of noodles involved in the production of the course It can be measured at a yam food during knitting or by unloving the yam from the knitted fabric

A PATTERN


Row autumn row is a horizontal a row of needle loops produced by adjacent needles 

KNITTING DENSITY

density Is the total number of loops in a unit area such as a square inch or a square centimeter e obtained by multiplying the number of courses and wales per inch or centimeter teether Cop  wales per inch and stitch density are the most important parameters of a knitted fane and ae set before and calculated later very accurately for determinıng the quality of the knitted Gibbs  

THE NEEDLE

The hooked metal needle is the principal knitting element of the knitting machine Pnor to yam feeding the needle is raised to clear the old loop from the hook and to receive the new the loop above it on the needle stum The new loop is then enclosed in the needle hook as the needle starts to descend
The hook then draws the new loop down through the old loop as the latter slides over the outside of the descending bridge of the closed hook All needles must, therefore, have some method of closing the needle hook to retain the new loop and exclude the old loop

FABRIC DRAW-OFF

The fabric loops are always drawn from the needles on the side remote from their hooks When two cis of needles arc employed, either arranged vertically back-to-back or at some other angle to each other, each set of hooks will face away from the other set and the fabric will be produced and drawn away in the gap between the two sets.

TECHNICALLY UPRIGHT


Knitted fabric is technically upright when its courses run horizontally and its wales run vertically, with the heads of the needle loops facing towards the top of the fabric and the course knitted first situated at the bottom of the fabric
