Embodiment Construction

[0013] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0014] The direct product of the present invention is a colored product, which normally needs secondary processing to be colored, and the secondary processing has high pollution. The product is not available in China, no dyeing is required, and secondary operations are reduced.

[0015] The production process is mainly divided into the following four processes:

[0016] (1) Preparation of color masterbatch

[0017] The masterbatch is mainly composed of three parts, which are dyestuff, carrier resin and dispersant. Prepare dyes according to product requirements. The carrier resin is made of high-viscosity nylon 66 slices, an...

Abstract

The invention discloses a method for preparing nylon 66 colored and low-denier industrial yarns by a solution staining method. The method comprises the following steps: before spinning, adding color-different dyes, such as carbon black, and a dispersing agent polyethylene wax in a few of nylon 66 slices to prepare masterbatch; uniformly mixing the masterbatch with the raw material nylon 66 slices; and then carrying out spinning processes such as melting, spinning, drawing and winding, so as to prepare a finished product. In addition, the direct product of the preparation method is a colored product which normally needs to perform secondary processing for dyeing, and the secondary processing is high in pollution. The product prepared by the method is creative in China, does not need dyeing and reduces secondary operation.

Description

technical field [0001] The invention belongs to the technical field of industrial yarns, in particular to a method for preparing nylon 66 colored low-denier industrial yarns. Background technique [0002] At present, colored low-denier industrial yarn normally requires secondary processing to be colored, and secondary processing has high pollution. Existing nylon 66 low-denier industrial yarn, but there is no preparation method for directly colored nylon 66 colored low-denier industrial yarn. Color requires a secondary operation. In addition, nylon 66 industrial yarn is widely used in cord fabrics, conveyor belts and other fields because of its high strength, high heat resistance and high wear resistance. At present, the dyeing process of nylon 66 industrial yarn is to spin the yarn first and then dye and finish the finished yarn. The disadvantage of this process is that the dyeing cost is high, the pollution to the environment is great, and the strength of the finished ya...
