Problems solved by technology

[0003] At present, sodium alginate and modified starch are mostly used in the digital inkjet printing sizing treatment of cotton fabrics. For example, US20130235118A1 discloses an inkjet printing method for cotton fabrics. A sizing agent, the main component of which is modified starch; the Chinese patent No. 200810201472.8 "A Color Fixing Method and Equipment for Cotton Fabric Active Ink Inkjet Printing", the sizing agent is sodium alginate, carboxymethyl starch or Hydroxyethyl starch, the modified starch in the above patents has a low degree of substitution, and reactive dyes can react with unmodified starch, which greatly affects the color yield of digital inkjet printing, and causes printed cotton Fabric feels rough

Abstract

The invention discloses a reactive dye ink jet printing sizing agent for cotton fabric and belongs to the technical field of ink jet printing. The reactive dye ink jet printing sizing agent for the cotton fabric comprises sodium alginate, sodium carboxymethyl cellulose, hydroxypropyl guar gum, a dispersing agent and a migration inhibitor. The sizing agent can increase the reactive dye ink jet printing color yield without affecting the hand feeling of the cotton fabric after printing.

Description

technical field [0001] The invention relates to a sizing agent for ink-jet printing of cotton fabric reactive dye ink, which belongs to the technical field of ink-jet printing. Background technique [0002] Most of the digital inkjet printing of cotton fabrics uses reactive dye inks. In order to ensure the color yield and clarity of printing, cotton fabrics need to be sized. Ensure that the reactive dye ink can keep the shape of the jet printing and be fixed on the cotton fabric when it is steamed after jet printing. [0003] At present, sodium alginate and modified starch are mostly used in digital inkjet printing sizing of cotton fabrics. For example, US20130235118A1 discloses a sizing agent for inkjet printing of cotton fabrics. The main component of the sizing agent is modified starch; the patent number is 200810201472.8 Chinese patent "Cotton Fabric Reactive Ink Inkjet Printing Method and Equipment", the sizing agent is sodium alginate, carboxymethyl starch or hydroxye...
