Problems solved by technology

Yet because the superfine polyester-nylon composite fiber in the prior art is all this white, after it is further processed into textile product, must just can obtain the textile product of the various color and luster required by the user by dyeing, thereby cause following two Insufficient aspects: First, as a textile product made of ultra-fine polyester-nylon composite fiber, the single-filament fineness after fiber opening is only about 0.08dtex. Because the single-filament fineness is extremely fine, the color fastness and color The vividness cannot meet the requirements of some high-grade dark textile products and bright textile products, which limits the application range of the products; second, any textile products will produce a large amount of industrial waste gas and Sewage, which seriously pollutes the environment and endangers health

Abstract

The invention relates to a colored ultra-fine polyester / nylon composite fiber and a processing method thereof. The colored ultra-fine nylon / polyester composite fiber is formed by the following materials according to weight part: 62 portions to 82 portions of polyester chips, 15 portions to 35 portions of nylon chips, 1 portion to 3.5 portions of polyester colored master batches and 0.5 portion to 2 portions of nylon colored master batches. The invention has the advantages that: as the polyester colored master batches and the nylon colored master batches are added into the raw material of the polyester chips and the nylon chips, coloring requirement before spinning is met, thus causing spun products not to require dyeing; textile products produced by using the colored ultra-fine polyester / nylon composite fiber has the color fastness much better than that of textile products by dyeing; in addition, the processing method makes up the defect that the textile products of the ultra-fine polyester / nylon composite fiber can not be dyed into dark colors, widens the application scope of the ultra-fine polyester / nylon composite fiber in the field of the textile products; does not need dyeing processing, thus avoiding environmental pollution caused by the textile products due to dyeing; has reasonable processing conditions, and can carry out production with the assistance of the traditional double-component equipment; the colored ultra-fine polyester / nylon composite fiber has all the properties and styles of the ultra-fine polyester / nylon composite fibers with true colors.

Description

technical field [0001] The invention belongs to the technical field of superfine polyester-nylon composite fiber and its processing, and in particular relates to a colored superfine polyester-nylon composite fiber, and also relates to a processing method of the fiber. Background technique [0002] The current ultra-fine polyester-nylon composite fiber products are all made of a certain proportion of polyester and nylon through composite spinning, false twist deformation or stretching processes. Strong water absorption and decontamination performance, super soft performance and super simulation performance, and also have the physical properties of high elasticity, high strength, wear resistance and corrosion resistance common to synthetic fibers. Yet because the superfine polyester-nylon composite fiber in the prior art is all this white, after it is further processed into textile product, must just can obtain the textile product of the various color and luster required by th...
