Embodiment 1

[0021] The preparation and processing method of a segment color knitting yarn described in this embodiment, the steps are as follows:

[0022] The first step is the selection of raw materials: 100% 17.5um mercerized merino wool;

[0023] The second step, dyeing treatment: mix at room temperature with a bath ratio of 1:8, and add 0.5g / L of glacial acetic acid, 0.8g / L of leveling agent Abaig B and the addition of 2% from shallow Apply reactive dyes to dark wool and keep it for 10 minutes, then raise the temperature at 0.8°C per minute to 50°C, then raise the temperature to 85°C at 1°C per minute, and keep it for 50 minutes, then stop the temperature rise and make it rise at a rate of 0.8°C per minute Cool down to 70°C and keep it for 5 minutes, then cool down to 50°C at 1°C per minute, and finally cool down naturally to complete the dyeing process, and keep the pH value at 5 throughout the dyeing process; the pH value of Merino wool after dyeing is The value is 6, that is, the ...

Embodiment 2

[0030] The preparation and processing method of a segment color knitting yarn described in this embodiment, the steps are as follows:

[0031] The first step is the selection of raw materials: 50% 19.5um mercerized merino wool and 50% cotton fiber;

[0032]The second step, dyeing treatment: mix at room temperature with a bath ratio of 1:8, and add 0.5g / L of glacial acetic acid, 0.8g / L of leveling agent Abaig B and the addition of 2% from shallow Use reactive dyes for dark wool and keep it for 10 minutes, then raise the temperature at 0.8°C per minute to 50°C, then raise the temperature at 1°C per minute to 85°C, keep it for 50 minutes, and then stop the dyeing process of mercerized Merino wool.

Abstract

The invention relates to the field of spinning yarns and especially relates to a preparation and processing method for a colored knitting yarn. The invention aims to provide the preparation and processing method for the colored knitting yarn with soft hand feel, high comfort level and level-3 anti-pilling effect. The method comprises the following steps: 1) selecting raw materials: 100% 17.5mu m mercerizing merino wool; 2) dyeing treatment: preparing at a bath ratio of (1:8)-(1:10) at room temperature, adding 0.5-1g / L glacial acetic acid, 0.5-1g / L leveling agent Albegal B and 0-3% of activated dye for wool from shallow to deep, keeping for 10 minutes, raising the temperature to 45-55 DEG C at the raising speed of 0.8 DEG C per minute, then raising the temperature to 80-90 DEG C at the raising speed of 1 DEG C per minute, keeping for 45-60 minutes, stopping temperature rise, reducing the temperature to 65-75 DEG C at the reducing speed of 0.8 DEG C per minute, keeping for 5 minutes, then reducing the temperature to 45-55 DEG C at the reducing speed of 1 DEG C per minute, and finally naturally cooling, thereby finishing the dyeing treatment, wherein the PH value is kept at 4-6 in the whole dyeing process.

Description

technical field [0001] The invention relates to the field of textile yarns, in particular to a method for preparing and processing segment-color knitting yarns. Background technique [0002] With the improvement of people's living standards, people's requirements for clothing are getting higher and higher. Consumers have developed from the initial pursuit of warmth to comfort, beauty, and health. Therefore, functional textiles have emerged as the times require. [0003] Segment colored yarn is a new type of compound yarn. It is a new type of colored yarn produced by appropriate transformation on ring spinning frame in recent years. It has a new style of multi-color combination, which is different from ordinary flower yarn. Segment-colored yarns present irregular and unique color effects. In the axial direction of the yarn, there are not only changes in thickness, but also fancy colors that appear alternately in discontinuous distribution. Segment-colored yarn has both color...
