Synthetic Sizing Agents for Filament and Synthetic Warps
topic
Synthetic warp yarns from polyester, nylon, and acrylic fibres require sizing agents with specific adhesion to synthetic fibre surfaces that natural starches cannot provide, with polyacrylate, polyester, and CMC-based sizing compounds formulated for adhesion to hydrophobic synthetic surfaces through physical film formation rather than the cellulose bonding that makes starch effective on cotton, with post-weaving size removal requiring size-specific desizing chemistry compatible with the synthetic substrate.
Role
Enables sizing of synthetic spun yarn warps that otherwise lack the inter-fibre cohesion and surface strength needed for high-speed weaving, with synthetic size formulation requiring careful selection for adhesion to the specific synthetic fibre type and for compatibility with subsequent dyeing and finishing processes where size residues must be completely removed to achieve level dyeing results on synthetic fibres.
