Velvetol 251 CCG is a versatile polyester polymer used for finishing polyester fabrics. It has a certain hydrophilicity and soft hand feeling, which can reduce the static electricity generated by Chinese VELVET fabric suppliers and garments. First, the basic properties: Chemical properties: low molecular weight pro-ester polyester compound Appearance: light white to dark brown particles Solid content: 97% ionic: non-ionic PH (concentration 5%): 6.0 Solubility: good mixing 80-85 degrees can be completely dispersed in the solution. Flash point: more than 93 degrees. 2. Function: Good decontamination and durable moisture wicking function, which can make Chinese VELVET fabric suppliers get the same finishing effect as cotton VELVET fabric suppliers. China VELVET China VELVET fabric supplier supplier can give good antistatic function to China inkjet dyeing China VELVET China VELVET fabric supplier supplier, with soft lubrication in the bath, good degreasing ability in preparation and refining process VELVET fabric suppliers are soft to the touch and have good drape dyeing, which can reduce the friction of Chinese VELVET fabric suppliers,
reduce the crease caused by friction and improve the exhaustion rate of Chinese VELVET fabric suppliers, thus reducing the discharge of dyeing waste liquid. China VELVET fabric suppliers can obtain the effect of silicone-like finishing The body preparation step suggests dispersing the product in water at a concentration of no more than 25%, and the stability of the dispersion is generally good at a concentration of 10-15%. If the concentration exceeds 25%, the viscosity of the dispersion is too high to form a uniform dispersion. In order to obtain a stable dispersion, a high shear mixer (3000 rpm) is required. It is recommended to follow the steps below. Direct dissolution method: 1) Weigh the required weight of Velvetol 251 CCG and water at room temperature 2) Start the mixing tank stirrer, adjust the stirring speed to 300 rpm or more 3) Add 0.2% concentration to the mixing tank Acetic acid, adjust the pH to 5 - 64) to 50 degrees Celsius, the final temperature does not exceed 70 degrees Celsius, it is recommended to adjust the temperature to 60-70 degrees Celsius 5) Slowly prepare the previously prepared concentration of 10-15% Velvetol 251 CCG dispersion Pour into the mixing tank 6)
The dissolution process takes about 8 hours, sometimes more than 12 hours. Need constant stirring until completely dissolved 7) Add wetting penetrant to improve product stability and effectiveness 2) Start the mixing tank stirrer, adjust the stirring speed to 300 rpm or more 3) Add concentration to the mixing tank For 0.2% acetic acid, adjust the pH to 5-64) and heat up to 50 degrees Celsius, keep the temperature below 50 degrees Celsius. It is recommended to adjust the final working temperature to 60-70 degrees Celsius. 5) Heat Vevetol 251 CCG with hot steam. Until the melting is complete 6) Transfer the molten Velvetol 251 CCG to the mixing tank (water temperature 50 ° C) 7) It takes 2-3 hours to dissolve, sometimes more than 8 hours. Stir constantly until completely dissolved. 8) Refer to the seventh method of direct dissolution method to control the concentration of Velvetol 251 CCG to 10-15%. 9) After filtration, package
4. Dispersion effect Velvetol 251 CCG dispersion is applied to China VELVET China. The surface layer of VELVET fabric supplier suppliers, after exhaustion and hot melt padding, can obtain a variety of performance formulas as follows: leveling agent 2.0-1.0% (to China VELVET fabric supplier) 0.2-0.1% Velvetol 251 CCG China VELVET fabric supplier finishing 1.0-3.0% (to dye bath weight) 0.1-0.3% Velvetol 251 CCG dispersion Note to avoid the following situations: ? Mix with cation-containing substances? Dry humidity is greater than 150 degrees? Dye bath PH Values above 8.0? Velvetol 251 CCG dispersion in the presence of electrolyte in the mixing tank V. Absorption characteristics and antistatic properties: Velvetol 251 CCG has good hydrophilicity in China VELVET China VELVET fabric supplier supplier And wicking moisture absorption, so China VELVET China VELVET fabric supplier suppliers get the same finishing effect as cotton, Velvetol 251 CCG China can reduce VELVET fabric suppliers and generation of static electricity on clothing, and quickly block out the static electricity generated, even with the washability. The table below shows the antistatic properties of Chinese VELVET fabric suppliers after treatment with a Velkeol 251 CCG dispersion at a concentration of 20 g/l. The rolling rate is 30% static (volt half-life (seconds) after 760 washes for 30 minutes before washing. 53 VI. Packing: Specification 25KG/bag, placed on the tray.
