Saint-Gobain Vetrotex - Laid scrim processing

	Description of the process
	Our products available for this process

he weaving process permits by using the leno weave pattern the production of mesh fabrics that are flat structure in which both warp and weft yarns are widely spaced to form a grid. Grinding wheels and fabrics for External Insulation Facade Systems (EIFS) use the advantages of this type of fabric.

The laid scrim machine is an other textile process that allows the manufacture of products called scrims in which the warp and weft are
also widely spaced and fixed by chemical means.



	The laid scrim is produced in 3 basic steps: Step 1: warp yarns sheet are fed from section beams or directly from a creel. Step 2: a special rotating device also called turbine lays filling yarns at high-speed on/ or between the warp sheets. The scrim is immediately impregnated with an adhesive system in order to maintain a regular space between weft and warp yarns. Step 3: the scrim is then dried, thermally treated and wound on a tube by a separate device.



	The scrims are mainly used for applications for which high tensile strength is required. Saint-Gobain Vetrotex yarns (based on 9, 11, 13µm filaments) sized with T6G/M, 5310C and 876s suit that requirement and perform well in weft direction despite the very brutal insertion caused by the rotating device.
