for this process
aint-Gobain Vetrotex yarns can be used on Warp Knitting Machine to produce knit scrim for self adhesive joint tape as well elastic casting tape for plaster reinforcement in medical application.


Glass yarns can be also processed on conventional weft knitting machine but in that case due to high bending strains, use of plied yarns as well as fine filaments are required.


Knit goods are planar or tubular structures made by
inter-looping of loops of yarns connected by a knitting system in length direction (warp knitting) or in the width direction (weft knitting).

The warp-knitting machine is fed with section beams, each end passes trough a needle. Knitting elements form loops and bind
the warp yarns together.

For production of knit scrim a feeder device inserts crosswise glass weft yarn: Additional synthetic warp yarns pulled from a beam combine trough the knitting elements the warp and weft glass yarns together
to shape the desired structure.

The weft-knitting machine is fed directly by a determined number
of yarns. The loop forming device uses latch needles that require products with high flexibility.





All Saint-Gobain Vetrotex glass yarns sized with textile sizes
can be used for the production of knit scrim, however, high tensile strength is needed and the T6 sized products are highly recommended.

For plaster reinforcement, the 6µm 66 tex (DE 75) T30G yarns suit fully the flexibility requirement for warp knitting.

Single made with 5, 7 or 6 µm filament (D, E, DE filament) are recommended for weft knitting.
