Problems solved by technology

[0005] (2) Because the material of the flat screen screen is nylon screen, the holes of the flat screen screen showing the pattern are relatively small, and the lines printed on the cloth surface will be relatively thin. This characteristic determines that the flat screen is very It is suitable for printing relatively fine patterns, of course, it can also print relatively rough patterns, but from an economic point of view, the factory does not consider this method
In addition, because the flat screen screen covers a relatively large area, if the blanket printing pattern is complex and the composition of color registration is relatively large, the number of flat screen screens required for flat screen printing is large, so the length of the flat screen printing machine Longer, requiring a lot of space for the length of the workshop

Abstract

The invention belongs to the field of textile printing and dyeing, and particularly discloses a large-diameter printing roller capable of replacing woolen blanket flat screen printing, also known as a rotary printing screen. The large-diameter printing roller is a hollow cylindrical roller. Thin and small screen holes are evenly distributed in the surface of the roller, and the number of the thin and small screen holes is required according to the woolen blanket printing production process. The invention further discloses a manufacturing process of the large-diameter printing roller. The large-diameter printing roller is suitable for woolen blanket printing, and printed patterns are finer and softer; by means of the characteristics of ductility and wear resistance of metallic nickel, the service life of the printing roller is long; continuous printing is achieved; and the space of a plant is saved.

Description

Technical field [0001] The invention belongs to the field of textile printing and dyeing, and in particular relates to a large-diameter printing roller for replacing flat screen printing on blankets and a manufacturing process thereof. Background technique [0002] Blankets are woven or knitted fabrics. There are many types and a wide range of uses. They are classified according to the weaving method. There are ① woven blankets, ② tufted blankets, ③ woven blankets, ④ Raschel blankets (warp knitted blankets), ⑤ acrylic Blankets (weft knitted blankets), etc., because blankets are different from general home textiles, the fabric size and pattern area are relatively large, the pattern and flower circumference area printed are also relatively large, and because of the height (thickness) of the blanket It is thicker than general textiles, and the printing paste required is heavier, so all existing blanket printing uses flat screen printing. The flat screen screen used for printing is ...
