Top-Size® PS
represents the latest technical developments in applying a smooth, clear, strong and highly flexible sizing film around the yarn.
Traditional modified starches form brittle sizing films with limited tenacity/elongation, this a compensated by formulating a size with additional additives like Wax, PVA, Acrylates or CMC.

Flexibility, elongation and tensile strength of the sizing film covering the yarn are very important parameters for an optimal sizing result.

Top-Size® PS
Young’s Modulus (Elastic Modulus) reaches 700-780 N/mm2 , with 207N/mm2 for a tradional starch sizing film, a 275% increase.

Top-Size® PS
elongation(before break) at 23.02% is very favourable compared to the 2-3% for a standard sizing formulation., a difference of 650%,

Top-Size® PS
Tensile strength 12.1 Mpa(N/mm2) is 200% higher than a 70% Starch/30% PVA blend, and similar to the tensile strength of 100% PVA.

Top-Size® PS
Yarn Sizing products are the result of HANSELAND R&D work. Top-Size® PS granular shape powder reduces dust formation when handling, 100% natural, and thus 100% biodegradable. REACH registrationis not required.
