Abstract

The invention provides a saponification dyeing method of polyamide acetate fiber composite yarns. The method includes the steps: (1) carrying out saponification modification treatment of the polyamideacetate fiber composite yarns which needs dyeing; (2) dyeing the polyamide acetate fiber composite yarns after saponification modification treatment with a reactive dye; (3) dyeing with a dispersed acidic dye; and (4) washing with water after dyeing. Firstly, an acetic acid fiber component contained in the polyamide acetate fiber filament composite yarns is subjected to partial saponification modification, after the modification of the acetic acid fiber, the reactive dye is adopted, dyeing is performed by a dispersed and acidic dye two-bath dyeing process, and the polyamide acetate fiber filament composite yarns are dyed by the creative dyeing method and have the advantages of bright color and luster, elegant luster, bright dyeing, strong dyeing fastness, and soft and smooth hand feeling.The soaping fastness of a dark color system can reach 4 level or more.

Description

Technical field: [0001] The invention relates to a method for saponification dyeing of nylon acetate fiber composite yarn, which belongs to the technical field of spinning technology. Background technique: [0002] Acetate fiber (Acetel) has the unique properties like real silk, fiber luster and bright color, excellent drapability and hand feeling. The knitted fabric produced by it has the advantages of smooth hand feeling, comfortable wearing, moisture absorption and breathability, light texture, low moisture regain, not easy to pilling, antistatic, etc., and is non-toxic, harmless, and non-allergic to skin contact for a long time. CA is easy to wet, has good liquid permeability and excellent absorbency, and is comfortable to wear and absorbs sweat. However, when CA is soaked, it also has the disadvantage of decreasing strength. It can be used as mixed fertilizer or incinerated, and has no impact on the environment. Diacetate spinning grade cellulose acetate: spinning grad...
