Example Embodiment

[0035] Example one

[0036] This embodiment provides a disperse dye continuous pad dyeing method for nylon webbing, which includes the following steps:

[0037] 1. Pre-treatment: Using 43-800 nylon ribbon made of nylon 6, the blank ribbon is processed according to the steps of ribbon drop-seam head-refining treatment-drying. The ribbon drop is to arrange the ribbon into The state suitable for refining and dyeing is equivalent to the opening process of the cloth, so that the brocade ribbon to be refined and dyed remains flat and does not form twists. The seam head is made of aramid sutures to keep the joints as straight as possible without bulging. Then the nylon ribbons are treated with refining liquid at a temperature of 86±1℃, and the speed of the refining process is 8m / min. After the refining process is completed, it is dried in a hot air oven at 130°C.

[0038] 2. Dyeing treatment: the two brocade ribbons after refining are placed in parallel at the same time, the speed of the ...

Example Embodiment

[0043] Example two

[0044] The main difference between this embodiment and the first embodiment is that: 20-150 nylon ribbon made of nylon 6 is used, and the blank ribbon of the brocade ribbon is subjected to tape-sewing treatment and then directly dyed, and the two brocade ribbons are placed side by side at the same time. Enter the belt, the speed of the control equipment is 9m / min, the extension ratio is 100%, the pre-treated brocade ribbon is padding and dispersing the dye solution at a temperature of 42±2℃, and the padding pressure is adjusted to 2.2bar and the padding tension is 2.5bar, after two dipping and two rolling, follow the steps of infrared pre-baking-hot melt baking-reduction cleaning-washing-drying to process the brocade ribbon. Among them, the infrared pre-baking temperature is 100°C, and the hot-melt baking temperature is 165°C, and then the brocade ribbon is cleaned with a reducing lotion, and the temperature of the reducing lotion is set to be kept within the...

Example Embodiment

[0047] Embodiment three:

[0048] The main difference between this embodiment and the first embodiment is: the 11-600 nylon ribbon made of nylon 6 is used, and the blank ribbon of the brocade ribbon is subjected to the drop-stitching process and the dyeing process is performed directly, and the two brocade ribbons are placed side by side at the same time. Enter the belt, the speed of the control equipment is 8m / min, the extension ratio is 100%, the pre-treated brocade ribbon is padding and dispersing the dye solution at 62±2℃, adjusting the padding pressure to 3bar and padding tension to 2bar After two dipping and two rolling, the brocade ribbon is processed according to the steps of infrared pre-baking-hot melt baking-reduction cleaning-washing-drying. Among them, the infrared pre-baking temperature is 120°C, and the hot-melt baking temperature is 200°C, and then the brocade ribbon is cleaned with a reducing lotion, and the temperature of the reducing lotion is set to be kept wi...

Abstract

The invention relates to a continuous disperse dye pad-dyeing method for polyamide braids and fabrics and belongs to the technical field of textile dyeing and printing. According to the adopted technical scheme, the continuous disperse dye pad-dyeing method for polyamide braids and fabrics comprises the following steps that dyeing treatment is conducted on the polyamide braids or fabrics, whereina padding dispersion dye is adopted for the dyeing treatment, and then infrared preheating, hot-melting, baking and drying, reduced cleaning, washing and drying performed are performed after dyeing treatment. The continuous disperse dye pad-dyeing method has the advantages of being simple in process, stable in quality and high in production and processing efficiency, the influence on the physicaland mechanical properties of the polyamide braids or fabrics in the dyeing process is small, the influence of chemical assistants on the colors and color fastness of products after dyeing is small, and dyes have the higher capability of covering defects of fabrics.

Description

technical field [0001] The invention relates to the technical field of textile printing and dyeing, in particular to a method for continuous pad dyeing of nylon ribbons and fabrics with disperse dyes. Background technique [0002] Nylon, also known as nylon and polyamide fiber, is a synthetic fiber with high strength, high wear resistance, chemical resistance and self-lubrication, and has excellent physical and mechanical properties. According to the molecular structure of nylon fiber, it can be divided into polyhexamethylene adipate represented by nylon 66 and caprolactam condensation polymer or ring-opened polymer represented by nylon 6, all of which are composed of linear macromolecules with amide bonds. It is the main raw material of various elastic fabrics on the market, widely used in various textile products, and has high civilian value. [0003] Due to the special molecular structure and organizational structure of nylon, neutral or acid dyes are usually used to dye...
