Abstract

The invention provides a spot-spray dyeing process of yarn. The spot-spray dyeing process can be used for solving the problems that speck yarn prepared by adopting an existing method is easy to fall in speck, single in style and low in production efficiency. The spot-spray dyeing process comprises the following steps of (1), pretreatment: enabling raw yarn to be corresponding to a vat site of a spray vat to thread the yarn, bleaching the yarn by utilizing the spray vat and a dyeing vat, dehydrating after the yarn is bleached, oven-drying, rewinding and enabling to be for later use; (2), spot-spray dyeing: determining to-be-used dye and processing process according to required color data and sample style, dissolving the dye, pouring into the dyeing vat, then dissolving an additive, adding into the dyeing vat, and correspondingly threading the yarn subjected to the pretreatment on a spray dyeing machine, carrying out spot spray on a section of the yarn on the spray dyeing machine according to the set processing process; (3), color fixation: flatly putting the yarn subjected to the spot spray on a yarn trolley, pushing into a steam box, carrying out steam braising, after the steam braising is finished well, opening a door of the steam box, cooling, and collecting the yarn; (4), post treatment: enabling the dyed yarn subjected to the spot spray to be corresponding to the vat site of the spray vat to load the yarn, washing with water, dehydrating, and oven-drying.

Description

technical field [0001] The invention relates to the technical field of yarn dyeing, in particular to a yarn spray dyeing process. Background technique [0002] Color-point yarn is a kind of yarn with various color dots attached to the surface of the yarn. Usually, the color dots are made of various short fibers and added to spinning after dyeing. The color dots made by this method In dotted yarn, not only dots are easy to fall off, but also due to the limitations of the spinning process, the dots are usually at fixed intervals, the style is relatively simple, and the production process is cumbersome and low in efficiency. Contents of the invention [0003] In view of the above problems, the present invention provides a yarn spray dyeing process, which can solve the problems that the colored dots of the colored dotted yarn prepared by the existing method are easy to fall off, the style is single, and the production efficiency is low. [0004] Its technical scheme is as fol...
