replacement of PVA sizing agent KS-218

Descripción del producto

KS***8 is a high substitute of PVA for textile sizing. The main components of KS***8 is polyether, it’s multi-block *****’s kind of linear macromolecule sizing agent synthesized by block ***** are Polyether and Polyphenyl ester in the molecular chain of phenyl ether while Polyphenyl ester chain is used to enhance the cohesion of serosa, improve the adhesion of terylene fiber and the biological degradation characteristics.Polyether chains give sizing agent of hydrophilic, toughness and desizing of film, get the advantages of Polyester and Polyol sizing agent, is especially suitable for terylene warp sizing. Specifications: Appearance: light yellow fine particle Viscosity:**5CP(*5℃，6%，1h) Volatility：≤*0% pH value：**7 Products performance: 1, Adhesion to the terylene fiber was higher than to PVA and polyacrylic acid sizing agent. 2, Low viscosity, good fluidity for “two high and one low”(high presure, high density, low viscosity)sizing technology. 3, Mix with modified starch, can finish warp sizing of T/C and terylene. 4, Mixing easily, saving working hours and energy. 5, Sizing dry ravel smoothly and reduce secondary filoplume. 6, The BOD5/CODcr of environmental KS series sizing agent is around 0.*5, much higher than the 0.**4 of PVA, do not pollute the environment. 7, Easy to desizing, reduce pollution. Operation introduction: 1, pH value was controlled between 6.**7.5 to make the sizing agent neutral. 2, When mixing the sizing, first feed modified starch, and then slowly add KS sizing agent, heated to *5℃, keep the temperature *0 minutes, corrected concentration, viscosity, ready for use. Package, storage and transportation: KS sizing agent packed *5KG/kraft bag. Storage should be dry, ventilated, note moisture when transport.
