Problems solved by technology

At present, nylon fancy yarns are generally made of various short fibers into particles, which are added to spinning after dyeing. No matter cotton spinning equipment or carded wool spinning equipment, colored wool particles can be kneaded. The yarn is generally thicker, the yarn style is single and the processing process is long
[0005] At present, there is no literature report on the processing method of preparing fancy yarn by direct dyeing of nylon fiber

Embodiment 1

[0039] The nylon fancy yarn online dyeing process described in the present embodiment 1 is made up of the following steps:

[0040] (1) Preparation of dye solution: 10% (mass percentage) of ethanol, 87% (mass percentage) of water, 1% of penetrant WA-M, 2% (mass percentage, Yorkshire) of acid dye red RED B-NG After mixing, stir until the dye is completely dissolved, and finally adjust the pH of the solution to 5.0 with acetic acid;

[0041] (2) Nylon dyeing: Add the prepared dye solution into the dyeing tank of a loose winder with a dyeing device, and then loosely wind the nylon 66 raw yarn with a yarn denier of 40D. The speed of the runner is 400m / min, and the speed of the runner is 15r / min. When the nylon yarn passes through the surface of the runner with the dye solution at high speed, the dye solution can quickly adhere and penetrate into the yarn, and the dyed yarn is red fancy Yarn, the molding density of nylon 66 fancy loose package yarn is 0.35g / cm 3 ;

Embodiment 2

[0045] The nylon fancy yarn online dyeing process described in the present embodiment 2 is made up of the following steps:

[0046] (1) Preparation of dye solution: 80% (mass percentage) of ethanol, 19.0% (mass percentage) of water, 0.5% of penetrant WA-M, and 0.5% (mass percentage, Huntsman Huntsman) of reactive dye blue B3G Mix to dissolve the dye completely, and finally adjust the pH of the solution to 3.0 with citric acid;

[0047] (2) Nylon dyeing: Add the prepared dye solution into the dyeing tank of the loose winder with dyeing device, and then loosely wind the nylon 6 yarn with a yarn denier of 60D, and the speed of the winder is 600m / min, the speed of the runner is 30r / min, when the nylon yarn passes through the surface of the runner with the dye solution at high speed, the dye solution can quickly adhere and penetrate into the yarn, and the dyed yarn is blue fancy Yarn, the molding density of nylon 6 fancy loose package yarn is 0.38g / cm 3 ;

Abstract

The invention belongs to the technical field of textile dyeing, and particularly relates to a polyamide fancy yarn online dyeing process. The method comprises the four steps of dye liquor preparation, polyamide dyeing, yarn steaming and color fixing and post-treatment. When the dye liquor is prepared, polyamide is dissolved by acid or reactive dye by adopting water, ethanol and a penetrant system in different proportions; and during dyeing, online dyeing is carried out by means of a loose type bobbin winder with a dyeing device, polyamide grey yarn or polyamide light-color yarn passes through the surface of a rotating wheel which rotates at a high speed, the surface of the rotating wheel is provided with dye liquor, the dye liquor is rapidly attached to and permeates into the yarn, and finally polyamide fancy yarn is formed. The method disclosed by the invention is simple in production operation, short in production and processing flow, green and environment-friendly in dyeing process, capable of realizing fabric style diversification and suitable for a small-batch and fast-paced production mode, and the dosage of the dyeing auxiliary agent is remarkably reduced.

Description

technical field [0001] The invention belongs to the technical field of textile dyeing, and in particular relates to an online dyeing process of nylon fancy yarn. Background technique [0002] Nylon is a synthetic fiber, and its outstanding advantages include: abrasion resistance is higher than other fibers, its abrasion resistance is 10 times higher than cotton, 20 times higher than wool, and its durability is excellent; high stretch elastic recovery rate, when pulled When it is stretched by 3-6%, the elastic recovery rate can reach 100%, and it can withstand tens of thousands of times of bending without breaking; the strength is high, and the strength of nylon fiber is 1-2 times higher than that of cotton and 4-5 times higher than that of wool. 3 times that of viscose. [0003] In addition, the hygroscopicity of nylon fabric is a better variety among synthetic fiber fabrics, so clothing made of nylon is more comfortable to wear than polyester clothing. Nylon fabric is a l...
