Embodiment Construction

[0016] 1. Preparation of matting agent solution

[0017] Anatase-grade manganese ion-coated titanium dioxide was selected as the matting agent.

[0018] First put titanium dioxide into the dissolution tank, then add water to make a solution with a concentration of 30%. At the same time, add the dispersant sodium phosphate. The amount added is 0.1-0.5% of the solution. Stir well to make it evenly mixed. Then the solution was dropped into a settling tank for 30 hours of settling. The solution after sedimentation is put into the preparation tank, and it is added with water to prepare a 25% titanium dioxide solution.

[0019] 2. Preparation of polyamide 66 resin

[0020] A 50% aqueous solution of nylon 66 salt is used or a 50% concentration solution is prepared by adding solid nylon 66 salt to deionized water. After it is transported to the horizontal tubular continuous polycondensation device, it is first evaporated and concentrated under normal pressure, and then the polyc...

Abstract

A process for preparing the full-dulling polyamide-66 resin and fibers includes such steps as preparing full-dulling solution, preparing full-dulling polymer, and polycondensating in horizontal tubular apparatus. Its advantages are low cost, high dulling effect.

Description

technical field [0001] The invention belongs to the research and development field of the manufacturing method of full-dull polyamide 66 resin and fiber. Background technique [0002] Along with the raising of people's living standard, for wearing natural fiber clothing more and more pursuit. The production of chemical fibers is also developing in the direction of imitating natural fibers. But at present, the matting technology of raw materials for chemical fiber production is not up to standard, which makes it difficult for the subsequent dyeing, the fiber matting is not good, and the chemical fiber product still has luster after dyeing. Because natural fibers have a unique soft luster, it is difficult to produce fibers that resemble natural fibers. In addition, some developed countries have produced full-dull chemical fibers, but the equipment for taxation is expensive, the process is complicated, and the production cost is high. Also do not use the process of the prese...
