Polyester fabric resist-dye printing

2025-03-24

To achieve patterned designs on the base color of polyester fabrics, resist printing is typically used instead of discharge printing. This is because polyester fabrics are usually dyed using disperse dyes, and once the dyeing process is complete—when the base-color dye has fully diffused into the polyester fibers—it becomes extremely difficult to completely remove or destroy the dye using the discharge-printing method.

How can the high-pressure sizing process be made to work more effectively?

Currently, shuttleless looms featuring characteristics such as "wide shed opening, narrow shed opening, powerful weft insertion, and high shedding frequency" are being widely introduced into China. This trend is placing increasingly stringent demands on pre-weaving processes, requiring warp and weft yarns to exhibit exceptional properties—such as high tensile strength, low strength variability, smooth yarn surfaces, minimal fuzziness, excellent abrasion resistance, and superior elongation properties. These qualities are essential to minimize warp and weft yarn breakages during weaving, ensuring the efficient operation of the looms.
