Problems solved by technology

[0002] As we all know, nylon dyeing has low color fastness, uneven dyeing, and low efficiency of weaving carpets after dyeing, which limits the application of nylon dyed yarns on carpets. Therefore, when carpet manufacturers use nylon yarns, they generally use Nylon is dyed with stock solution, but there are many unfavorable factors such as high cost, long delivery period, few color varieties, and difficulty in small batch production.
If package-dyed nylon can be developed to solve the three shortcomings of carpet weaving difficulty, low color fastness, and uneven dyeing, there will be a very large market demand. The key to package-dyed nylon technology is to solve the problem of color fastness and color fastness. Low and technical difficulties such as loss of yarn oil after dyeing and difficulty in weaving

Embodiment 1

[0024]1. Place the yarn to be dyed: take the yarn bobbin with gaps wrapped around the nylon yarn to be dyed and place it on the yarn rack in the main cylinder of the bobbin dyeing machine; 2. Configure dyes and leveling agents: dye in the bobbin Add 0.1%~2.8% of the weight of the nylon yarn to be dyed into the No. 1 chemical tank of the machine, add 180~240L of water to chemicalize the material, and then add the nylon yarn to be dyed into the No. 2 chemical tank Add 1%~3% leveling agent by weight and add 180~240L of water to chemicalize the material, and then raise the temperature in the No. 1 chemical tank and the No. 2 chemical tank to 30°C; 3. Dyeing : After the second chemical material is completed, turn on the feed pump switch of the control tank No. 2 of the bobbin dyeing machine to transport the leveling agent to the main vat. After the leveling agent is added, keep it for 10 minutes, and then turn it on The feed pump switch of the No. 1 chemical material tank delivers ...

Embodiment 2

[0027] The difference between this embodiment and embodiment 1 is that in step five, the temperature in the main vat is raised to 65° C., kept for 25 minutes, and finally drained to complete the dyeing. Other steps and parameters are the same as in embodiment 1.

[0028] Color fastness to washing of the dye obtained in the above process: grade 4; color fastness to light: grade 5; color fastness to rubbing: grade 5; color difference inside and outside the package: grade 5; deformation of the package after dyeing: 1CM.

Embodiment 3

[0030] The difference between this embodiment and Example 1 is that the parts by weight of the nylon yarn to be dyed, the dyestuff, the leveling agent and the oil agent are respectively 100 parts of the nylon yarn to be dyed, 0.5 parts of the dye, 1.2 parts of the leveling agent and 0.6 part of oil agent, other steps and parameter are identical with embodiment 1.

[0031] Color fastness to washing of the dye obtained in the above process: grade 5; color fastness to light: grade 5; color fastness to rubbing: grade 5; color difference inside and outside the package: grade 5; deformation of the package after dyeing: 2CM.

Abstract

The invention relates to the technical field of carpet yarn bobbin dyeing, in particular to a nylon yarn bobbin dyeing formula and a process method. The nylon yarn bobbin dyeing formula is characterized by comprising, by weight, 95-110 parts of to-be-dyed nylon yarns, 0.1-2.8 parts of dyes, 1-3 parts of a dye leveler and 0.5-1 part of an oiling agent. The process method includes: step one, placement of the to-be-dyed nylon yarns; step two, preparation of the dyes and the dye leveler; step three, dyeing; step four, cleaning; step five, aftertreatment. The nylon yarn bobbin dyeing formula and the process method have advantages of simple process, uniformity in dyeing, high color fastness, high carpet weaving efficiency and the like.
