Embodiment

[0020] a. Pre-setting: white cloth pre-setting temperature is 190°C, vehicle speed is 45 m / min;

[0021] b. Printing: Printing prescription: disperse dye 30-40g / kg, Remazol reactive dye 40-45g / kg, resist pigment S10-15g / kg, citric acid 10-15g / kg, mix the above formula with modified starch The paste is mixed to form printing paste printing;

[0022] c. Baking: Baking temperature 195°C, time 1min;

[0023] d. Rapid steaming of caustic soda: Prescription of soda caustic: 150g / L of soda ash, 100g / L of table salt, 100g / L of potassium carbonate, 100mL / L of caustic soda of 36 degrees Baume, 50%-60% of liquid squeezing rate, steaming temperature 130-135℃, steaming time 50s;

Abstract

The invention discloses a polyester/cotton fabric printing technology. The polyester/cotton fabric printing technology adopts the technical process as follows: preforming, printing, baking, performing alkali rolling and rapidly steaming, soaping, performing hot water washing, and drying. Through adoption of two-phase printing, the color fixing rate of disperse/reactive dye is greatly improved; through optimization of the disperse dye, the problem of background contamination easily caused by a disperse/reactive complete printing method is effectively solved; a color paste does not contain an alkaline agent, so that the color paste is high in stability and can be stored for more than two days; the polyester/cotton fabric printing technology is easy in production control and simple in pulping operation; a large amount of urea is saved, so that environment protection is benefited.

Description

[0001] technical field [0002] The invention belongs to a printing process, in particular to a polyester-cotton fabric printing process. [0003] Background technique [0004] Polyester-cotton fabric is a variety of fabrics woven from polyester fibers and cotton fiber blended yarns, commonly known as cotton fabrics. It has the advantages of scratchy appearance, durability, durability, stable size, easy washing and quick drying, etc., and is suitable for making all kinds of clothes. The printing of polyester-cotton fabrics mostly adopts the disperse / reactive all-material method for printing, which is to add alkaline agents, urea and other additives together with disperse and reactive dyes into the paste for printing, and then bake-steam under alkaline conditions to fix the color 1. Wash with water and soap. But the color fixation rate is low, and it is easy to cause the problem of white ground staining. [0005] Contents of the invention [0006] In order to overcome t...
