Sinker Design and Fabric Formation Role
topic
Knitting sinkers are thin steel blades positioned between needles that hold the fabric down during needle rise, form the underlap on warp knitting machines, and in terry machines use extended neb geometry to hold ground loops short while forming extended pile loops, with sinker geometry being a critical design parameter that determines the loop length, stitch density, and pile height characteristics of the knitted fabric structure.
Role
Controls the fabric formation geometry during the knitting cycle by holding formed loops against needle uplift that would cause dropped stitches and by defining the yarn presentation position that determines loop size, with sinker design being intimately connected to needle design and the two components requiring optimised co-design for each specific knitting application to achieve consistent loop formation and fabric quality.
