Sizing products
The MERTSIZE range.
Carboxymethyl grades, modified starches, one-shot compounds and synthetic sizes — with the waxes and lubricants that run alongside them.
Sizing agents coat the warp with a film that lays down hairiness, raises tensile strength and lets the yarn survive the friction of the loom. The right choice depends on your fibre, yarn count, loom type and — just as much — on how easily the size has to come off again afterwards.
Our range spans carboxymethyl grades, modified starches, one-shot compounds, a liquid polyester size for filament yarns and synthetic grades, with waxes, lubricants and binders alongside them. Every product ships with its technical data sheet, safety data sheet and a recommended starting recipe.
Sizing agents
From washable natural sizes through to fully synthetic, including dedicated grades for terry towel, polyester filament and denim.
Washable natural sizing agent, medium viscosity grade. Carboxymethyl starch — dissolves in water, so desizing needs no amylase enzyme.
How it works →Specially modified starch sizing agent for natural spun yarn, with or without synthetic add-ons.
Request TDS →Specially developed for terry towel sizing, reducing the quantity of size required by up to 70%.
Request TDS →Designed for terry towel and heavy constructions. It minimises fly and dust on both pile and ground warps, raising performance at the loom, and is equally suitable for cotton, viscose and their polyester blends.
Request TDS →The same approach as SC 100, formulated for coarse and medium yarn counts.
Request TDS →A blend of natural, synthetic and modified polymers for cotton, viscose and polyester blends. Yarns sized with it show high resistance to mechanical abrasion and to tensile force.
Request TDS →A blend of natural, synthetic and modified polymers for cotton, viscose and polyester blends. Yarns sized with it show high resistance to mechanical abrasion and to tensile force. A water-soluble polymer.
Request TDS →Comprehensive sizing agent for cotton, polyester, linen, viscose, wool and their blends — suitable across the full range of fibres and blends. A water-soluble polymer.
Request TDS →Liquid polyester sizing agent, developed in house for filament yarns. Suitable for air jet and water jet looms.
Request TDS →Special compound used to reduce the quantity of starch in the recipe, giving the yarn a smooth, slippery surface. Two concentrations of the same effect — tell us your recipe and we will advise which.
Request TDS →Compact sizing agent developed for denim. Runs on its own, or as part of the OASIS process together with MERT-DNM COVER for a shorter, lower-water route through dyeing and finishing.
How it works →Sizing auxiliaries
Waxes, lubricants, binders and antistatic agents used alongside the size to control friction, static, yarn handling and film properties.
Sizing lubricant that cuts yarn-to-yarn and yarn-to-metal friction, reducing breaks at high loom speeds. Keeps the size film flexible rather than brittle and controls static and lint. Highly water-soluble, so it washes out completely at desizing and leaves nothing behind for dyeing and finishing.
Request TDS →Liquid binder specially developed for the sizing process, giving flexible film properties.
Request TDS →Liquid antistatic agent for synthetic yarns. It reduces static build-up during weaving, which lifts loom efficiency — recommended wherever synthetic yarns are run.
Request TDS →Not sure which grade? Tell us the yarn count and construction, your loom type, current add-on and desizing regime. We will propose a starting recipe and send a lab sample free of charge.
Certification and packaging
Our products are OEKO-TEX certified and registered to ZDHC Level 3, the highest conformance level of the ZDHC Manufacturing Restricted Substances List. GOTS certification is in progress. Powder products are supplied in 25 kg bags, liquid products in drums and IBCs.
