Learn how circular knitting sinker timing affects polyester loop formation, stitch length, GSM uniformity, yarn friction and visible knitted fabric faults.

During polyester circular knitting, each yarn travels from a supply package through guides and feed mechanisms before becoming a knitted loop. Yarn running tension is the force along that moving yarn path. Measuring it can reveal feed problems that are not visible from the final knitted ro

Polyester jacquard knitting can create detailed patterns using selective needle actions and multiple yarns. In some constructions, a yarn passes behind sections without forming knitted stitches; these spans are called floats. Their length influences fabric structure, material usage and pra

Rib-knit polyester fabrics are produced using knitting arrangements that create alternating loop columns. On a double-knit circular machine, cylinder and dial needles cooperate under timed cam actions. Their relative timing is a distinct technical setting from machine gauge and influences

A polyester-Lycra knit may use two yarn components in the same stitch while presenting one more prominently on the garment face. This is yarn plating: guiding yarns into consistent relative positions as loops form. Proper plating is relevant to stretch sportswear, visual uniformity and con

Polyester-Lycra knitted fabric combines the structure of polyester yarn with the recovery of an elastane component. One important production setting is how much the elastane is extended during feeding, commonly discussed as elastane draft. Understanding it helps knitters control stretch, r

Knitting machine gauge measures the number of needles per inch. Learn how E20, E28 and E36 machines differ, how gauge relates to polyester yarn denier and loop structure, and why gauge alone does not determine finished GSM or fabric quality.

A sinker is a precision component used in many circular knitting machines. Learn how its nose, throat and belly help control polyester knitted loops, support needle movement and contribute to consistent stitch formation.

Fabric take-down tension controls how newly knitted polyester fabric moves away from circular knitting needles. Learn how the take-down system works, how it interacts with yarn feeding and stitch formation, and why balanced settings support consistent production.
