Embodiment 1

[0040] This embodiment provides a method for continuous pad dyeing of nylon webbing with acid dyes, and the specific steps are as follows:

[0041] Step 1, preparation before dyeing of nylon webbing

[0042] Process flow: Blank tape—dropping tape (the taro thread needs to be trimmed if there is a shuttle)—sewing head—refining—drying

[0043] ①Choose 20-150 plain weave brocade ribbon (nylon 6).

[0044] ②In the process of unloading, try to ensure that the webbing is as straight as possible without twisting;

[0045] ③The sewing head should be as straight as possible, and should not be twisted to form twists, so as to avoid wrinkles during the dyeing process, damage the groove roller, and cause quality problems.

[0046] ④ Refining process prescription:

[0047] Scouring agent 3g / L

[0048] Detergent 3g / L

[0049] Soda ash 1g / L

[0050] Note: Refining is carried out in two or more groups of washing tanks;

[0051] Refining process:

[0052] Vehicle speed, 8m / min;

Embodiment 2

[0076] This embodiment provides a method for continuous pad dyeing of nylon webbing with acid dyes, and the specific steps are as follows:

[0077] Step 1, preparation before dyeing of nylon webbing

[0078] Process flow: Blank tape—dropping tape (the taro thread needs to be trimmed if there is a shuttle)—sewing head—refining—drying

[0079] ①Choose 43-800 brocade ribbon (nylon 6).

[0080] ②In the process of unloading, try to ensure that the webbing is as straight as possible without twisting;

[0081] ③The sewing head should be as straight as possible, and should not be twisted to form twists, so as to avoid wrinkles during the dyeing process, damage the groove roller, and cause quality problems.

[0082] Step 2, dyeing of nylon webbing

[0083] ① Dyeing process of nylon webbing:

[0084] 43-800 brocade ribbon → infrared or hot air drying (100°C) → pad dyeing acid dye solution, acid release agent and color fixing agent 1 (two dipping and two padding, padding pressure 3.0...

Embodiment 3

[0102] This embodiment provides a method for continuous pad dyeing of nylon webbing with acid dyes, and the specific steps are as follows:

[0103] Step 1, preparation before dyeing of nylon webbing

[0104] Process flow: Blank tape—dropping tape (the taro thread needs to be trimmed if there is a shuttle)—sewing head—refining—drying

[0105] ①Choose 44-1700A brocade ribbon.

[0106] ②In the process of unloading, try to ensure that the webbing is as straight as possible without twisting;

[0107] ③The sewing head should be as straight as possible, and should not be twisted to form twists, so as to avoid wrinkles during the dyeing process, damage the groove roller, and cause quality problems.

[0108] ④ Refining process prescription:

[0109] Scouring agent 3g / L

[0110] Detergent 3g / L

[0111] Soda ash 1g / L

[0112] Note: Refining is carried out in two or more groups of washing tanks;

Abstract

The invention discloses an acid dye continuous pad dyeing method for polyamide woven tapes. The acid dye continuous pad dyeing method sequentially includes steps of 1, pretreating the polyamide woventapes; 2, drying the polyamide woven tapes by infrared rays or hot air; 3, simultaneously carrying out pad dyeing by acid dye liquor and color fixing agents; 4, carrying out steaming dyeing and primary color fixing treatment; 5, carrying out hot washing; 6, carrying out secondary color fixing treatment; 7, carrying out hot washing; 8 carrying out drying; 9, dropping tapes. The acid dye continuouspad dyeing method has the advantages that the polyamide woven tapes have bright colors by the aid of acid dye steaming processes and color fixing one-bath dyeing schemes, the dye depths of the polyamide woven tapes can be effectively increased, the acid dye continuous pad dyeing method is good in deep dyeing property in polyamide woven tape dyeing procedures, and the polyamide woven tapes can be dyed with rich dark colors by the aid of the acid dye continuous pad dyeing method; pad dyeing is carried out on the polyamide woven tapes by acid dye, combined effects can be realized by an early color fixing scheme and a late color fixing scheme, the dye and the woven tapes are firmly combined with one another by chemical bonds, and the problem of poor color fastness of existing polyamide woven tapes after burning-preventive finishing is carried out on the existing polyamide woven tapes can be effectively solved by the aid of the acid dye continuous pad dyeing method.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to an acid dye continuous pad dyeing method for nylon webbing. Background technique [0002] Because of its high strength, good wear resistance and resilience, nylon fiber is widely used in pure or blended clothing and knitwear, especially the blended nylon / cotton blend, which has a good hand feeling and makes the clothing more comfortable. It has good air permeability, good wear resistance and durability, and is favored by consumers. It is a medium-to-high-end raw material. [0003] Acid dyes are common dyes for dyeing nylon fabrics. They have bright colors, high dyeing percentage and fastness. Especially, pad dyeing is used to dye nylon fabrics, which has high production efficiency and small batch difference. However, after dyeing the nylon webbing with acid dyes, the color fastness of the nylon webbing after anti-burning finishing is poor. [0004] The published patent technol...
