Abstract

The invention relates to the field of yarn dyeing process, and particularly discloses a dyeing and finishing process of hollow fibers and tencel blended yarns, which can effectively improve color fastness. The dyeing and finishing process comprises the following steps: the first step: dyeing: dyeing light color and neutral color yarns by HGL at the temperature of 120 DEG C, and performing heat preservation for 30 minutes; dyeing deep color yarns by HGL at the temperature of 130 DEG C, and performing heat preservation for 30 minutes; the second step: reduction: adding sodium carbonate and detergent into water, wherein the concentration of both sodium carbonate and detergen is 2 g/L, and adding yarns dyed at the first step into the mixture according to the liquor ratio of 1 to 8, controlling the temperature to be 80 DEG C and performing heat preservation for 20 minutes; the third step: cleaning: cleaning the yarns by hot water at the temperature of 80 DEG C for 10 minutes, and then washing the yarns cleanly by cold water. When the light and neutral color yarns are dyed through the dyeing and finishing process of the hollow fibers and the tencel blended yarns, the dyeing temperature is controlled to be 120 DEG C, meanwhile, the sodium carbonate and the detergent are adopted during reduction, so that the color fastness of processed blended yarns is effectively improved, the color fastness of the processed blended yarns can reach the third level to the fourth level, and the serviceability is improved greatly.

Description

The dyeing and finishing technology of doughnut and tencel blended yarn

Technical field

The present invention relates to the yarn dyeing technology field, the dyeing and finishing technology of especially a kind of doughnut and tencel blended yarn.

Background technology

The dyeing and finishing technology of existing doughnut and tencel blended yarn, yarn to dark and shallow middle look all adopts same technique to carry out dyeing and finishing, adopt 130 ℃ of insulations while dyeing, after dyeing, adopt sodium hydrosulfite and soda ash to carry out reduction cleaning, cause the yarn of the dark series severity that fades, and the COLOR FASTNESS of whole yarn can only reach the 1-2 level, greatly reduce its serviceability, affect product quality.

Summary of the invention

The objective of the invention is the deficiency in order to solve above-mentioned technology and provide a kind of effectively to improve the doughnut of COLOR FASTNESS and the dyeing and finishing technology of tencel blended yarn.

In order to achieve the above object, the doughnut that the present invention is designed and the dyeing and finishing technology of tencel blended yarn, the first step, dyeing: for shallow middle dyed yarn line, O.W.F is below 2.0, HGL dyeing, temperature is controlled at 120 ℃, is incubated 30 minutes; For dark yarn, O.W.F is more than 2.0, HGL dyeing, and temperature is controlled at 130 ℃, is incubated 30 minutes; Second step, reduction: add soda ash and detergent in water, content is 2g/L, and the yarn after first step dyeing is added with bath raio 1:8, and temperature is controlled at 80 ℃, is incubated 20 minutes; The 3rd step, clean: with hot water, clean, temperature is controlled at 80 ℃, cleans 10 minutes, then with cold water, cleans up and gets final product.

The dyeing and finishing technology of the resulting doughnut of the present invention and tencel blended yarn, when it is dyeed to shallow middle dyed yarn line, the dyeing temperature adopted is controlled at 120 ℃, adopt soda ash and detergent when reduction simultaneously, can effectively improve the COLOR FASTNESS of the blended yarn after processing, make its COLOR FASTNESS can reach the 3-4 level, greatly improved serviceability and product quality.

The specific embodiment

The present invention is further described by the following embodiment.

Embodiment 1:

The doughnut that the present embodiment is described and the dyeing and finishing technology of tencel blended yarn, the first step, dyeing: for shallow middle dyed yarn line, O.W.F is below 2.0, HGL dyeing, temperature is controlled at 120 ℃, is incubated 30 minutes; For dark yarn, O.W.F is more than 2.0, HGL dyeing, and temperature is controlled at 130 ℃, is incubated 30 minutes; Second step, reduction: add soda ash and detergent in water, content is 2g/L, and the yarn after first step dyeing is added with bath raio 1:8, and temperature is controlled at 80 ℃, is incubated 20 minutes; The 3rd step, clean: with hot water, clean, temperature is controlled at 80 ℃, cleans 10 minutes, then with cold water, cleans up and gets final product.
