Textile Warp Size Additive

The process of weaving yarns into fabric places a lot of mechanical stress on the yarns, particularly those on the warp beam.  Warp size chemical is applied to protect the yarns to reduce the amount of yarn breaks that occur on the loom.

Traditionally this has been done using film formers (primarily starch and PVA), which improve abrasion resistance of the yarn.  Lawter has created a complimentary chemistry, which works together with film formers and which creates greater cohesion between the fibers of the yarn bundle.  Lawter’s warp size additive can penetrate the yarn and adhere to the surface of the fibers, which allows for a stronger, less hairy, and more compact yarn.

The result is fewer stops in both the warp and weft directions, the ability to wind more yarn on a weaver’s beam, and the potential to reduce the amount of film-former used:  since the yarn is more compact, there is less surface area for the film formers to coat.  This innovative additive addresses both the costs of raw materials and the constant fight to improve loom efficiency, helping weaving companies to improve the bottom line like never before.
