Size Recipe Formulation and Concentration Control
topic
Sizing recipe formulation combines film-forming agents including starch, polyvinyl alcohol, carboxymethyl cellulose, and acrylic polymers with lubricants, softeners, antistatic agents, and antimicrobial additives in defined concentrations prepared in cooking vessels at temperatures of 90 to 130 degrees Celsius, with in-line viscosity and concentration sensors maintaining size box concentration within defined control limits throughout production.
Role
Determines the chemical composition of the size coating applied to warp yarn that governs film cohesion strength, flexibility, yarn penetration depth, adhesion to fibre surface, and desizing ease, with recipe optimisation for each yarn type and weaving machine speed being the primary technical challenge of sizing management that directly determines weaving performance and fabric desizing completeness.
