Embodiment 1

[0015] Embodiment 1: select the dyeing machine of 200Kg capacity for use, load capacity is 200kg, package yarn is 40 counts of pure cotton worsted yarns, load package yarn layer and pile up a total of 10 layers from bottom to top, and the cylinder is full. The total concentration of dye added is 3 (o.w.f), and the dyeing full tank liquid level is 2200L, and the process flow is as follows:

[0016] First, the yarn is wound layer by layer onto the dyeing tube to form a cheese;

[0017] Then put the prepared package into the main cylinder of the dyeing machine, fill the package with water until the package is submerged, turn on the main pump, and then add 4g / L caustic soda and 8g / L hydrogen peroxide according to the process requirements for scouring. Drain after scouring, and then; inject clean water for washing, and drain after completion.

[0018] Add dye, 5g / L standard dosage of sodium hydrosulfate and 1.5g / L standard dosage of caustic soda into the master vat, put in cheese,...

Abstract

The invention discloses a bobbin dyeing technology, comprising the following steps: loose type spooling process, blanching pretreatment process, soap boiling process and drying process: putting prepared bobbin into a main cylinder of a dyeing machine, pouring water into the main cylinder until the bobbin is submerged; dyeing process: adding dyestuff into the main cylinder: 5g / L of sodium hydrosulfite and 1.5g / L of caustic soda; putting bobbin into the cylinder, then raising temperature to 50 DEG C and maintaining the temperature for 40min for carrying out full bath restoration, then discharging water when the full bath restoration is finished.The dyeing technology has the characteristics that use level of sodium hydrosulfite, caustic soda and temperature can be controlled, full bath restoration dyeing reaction can be adopted to ensure that the processed bobbin is evenly dyed, so that the problem that dyeing and flower dyeing are difficult.

Description

technical field [0001] The invention relates to a cheese dyeing process, in particular to a dyeing process applied to pure cotton cheese to prevent dyeing, and belongs to the technical field of textile printing and dyeing. Background technique [0002] At present, because cotton fabric is a natural cellulose fiber, it is widely used in yarn-dyed fabrics, knitted fabrics, decorative fabrics, embroidery threads, trademarks, high-end ties, epaulets and toys, etc. and is widely loved by consumers. However, the dyeing process of the traditional craft is easy to dye the package yarn, resulting in uneven color. After making cloth with these yarns, color difference and color flower will appear on the cloth surface, forming waste yarn and waste cloth. [0003] Chinese invention patent 200810236324.X discloses a cheese dyeing process. The dyeing process includes a pre-treatment dyeing process, a post-treatment process, and a drying process. A compound refining enzyme is added to the p...
