Title:
PRODUCTION METHOD OF POLYMER PARTICLE
Document Type and Number:
Japanese Patent JP2021024959
Kind Code:
A
Abstract:
To provide a method for producing polymer particles that provide excellent fastness of printing in washing and color hardly degraded even by washing of many times when used as ink for textile.SOLUTION: A production method of polymer particles includes the steps of: producing a liquid containing a particulate polymer having a chromophore by polymerization; and filtering the liquid by a plurality of filter membranes. The plurality of filter membranes includes a first filter membrane having an average pore diameter of 7 μm or less that the liquid penetrates first after polymerization and a second filter membrane having an average pore diameter of 1 μm or less.SELECTED DRAWING: None
