Colored yarn quality testing method

Abstract

The invention provides a colored yarn quality detection method; according to the method, the strength, shade and color fastness of colored yarn, the weaving effect and the color aberration of three layers of inner, middle and outer layers of yarn on cones are detected for determining if the dyeing effect of the colored yarn achieves production standards and meets follow-up production requirements, the production standards of the colored yarn are completely detected, the high accuracy of detection effect of each aspect can be ensured by the detection mode, the colored yarn which does not meet the production requirements can be effectively removed, single yarn strength detection of the colored yarn can ensure that the yarn has enough strength, shade and color fastness, the detection of the color aberration of the three layers of inner, middle and outer layers of the yarn on cones can ensure that the colored yarn has a good and uniform dyeing effect, and the detection of the weaving effect can ensure that a fabric knitted by the dyed colored yarn is soft and comfortable in hand feeling.

Description

technical field [0001] The invention relates to a quality detection method, in particular to a colored yarn quality detection method. Background technique [0002] It is one of the most important links in the whole production process that the dyed yarn obtained after dyeing the embryo yarn is used as a finished product to carry out standard testing in various aspects. Specifically, the single yarn strength, color light, and color fastness of the colored yarn obtained after dyeing the yarn, as well as the weaving effect of the colored yarn and the color difference between the inner, middle and outer layers of the package yarn, etc., all need to meet the production standards. If the dyed yarn detection after dyeing is not comprehensive or the measurement method is inaccurate, the obtained dyed yarn cannot be effectively screened, and it cannot provide a good guarantee for subsequent production, resulting in waste of resources and affecting production quality and production. b...
