Abstract

The invention discloses a printing adhesive for knitted fabrics. The printing adhesive is prepared from the following raw materials in parts by weight: 30-35 parts of polyester acrylate, 2-3 parts of lauryl sodium sulfate, 3-5 parts of N-hydroxyl methacrylamide, 6-9 parts of acrylic acid, 4-5 parts of trifluoroacetic acid, 9-12 parts of allyl heptanoate, 22-25 parts of acrylic dimethyl amino ethyl ester, 3-5 parts of vinyl glycidyl ether, 1-2 parts of 4-methyl guaiacol, 1-2 parts of ammonium persulfate, 3-4 parts of auxiliaries and 70-80 parts of water. The adhesive is good in light and heat resistance and good in elasticity, fails to absorb dust in air, and is relatively good in dyeing fastness; the adhesive, which performs graft modification through the N-hydroxyl methacrylamide, the acrylic acid and the like, has less possibility of being hydrolyzed unlike pure polyester acrylate, and is good in water resistance; the adhesive is suitable for printing knitted fabrics, has less possibility of breaking and is high in fastness.

Description

technical field [0001] The invention belongs to the technical field of textile printing and dyeing auxiliaries, in particular to a printing adhesive for knitted fabrics and a preparation method thereof. Background technique [0002] The so-called pigment printing is to fix the pigment which is insoluble in water and has no affinity and reactivity to the fabric on the fabric through the action of the adhesive, so as to achieve the purpose of coloring. According to the latest information, about half of the printed fabrics produced in the world are pigment printed. Pigment printing binder is the main component of pigment printing paste, and the quality of pigment printing finished products is directly affected by the performance of printing binder. [0003] At present, the quality of printing adhesives is different, and the printing defective rate caused by adhesive quality problems is more than 3%, causing huge economic losses, and the quality of printing adhesives direct...
