preparation example Construction

[0034] One embodiment of the present invention provides a method for preparing dyed nylon yarn, which includes the following step S10.

[0035] Step S10, performing scouring treatment on the undyed nylon yarn, and then performing dyeing treatment and soaping treatment in sequence to obtain dyed nylon yarn.

[0036] The above dyeing step includes the following step S11.

[0037] Step S11. Dip the refined nylon yarn in the aqueous solution of ERIOFAST reactive dye at 40°C to 45°C, perform the first dyeing treatment for not less than 15 minutes, and then add calcium chloride to continue for not less than 5 minutes After the second dyeing treatment, add acetic acid and sodium acetate to continue the third dyeing treatment for no less than 5 minutes; then raise the temperature to 55°C-98°C and continue the fourth dyeing treatment for no less than 50 minutes;

[0038] Among them, the OWF of ERIOFAST reactive dyes is less than 1.0%.

[0039] In the preparation method of the above-m...

Embodiment 1

[0090] (1) Dye a cylinder of 70D (40D) nylon elastic cheese in a dyeing cylinder with a diameter of 1800mm, the yarn weight is 425kg, and the liquor ratio is 1:11.

[0091] (2) After the nylon elastic cheese yarn is put into the vat, enter clean water, add refining agent EPDC010.9g / L, heat up to 85°C, refine for 20 minutes, drain, then enter clean water, wash at room temperature for 5 minutes, and then drain.

Abstract

The invention relates to a dyed nylon yarn, a preparation method thereof and a textile product. According to the preparation method of the dyed nylon yarn, undyed nylon yarn is subjected to refining treatment and then sequentially subjected to dyeing treatment and soaping treatment, and the dyed nylon yarn is obtained; the dyeing treatment comprises the following steps: at 40-45 DEG C, soaking the refined nylon yarn in an aqueous solution of an ERIOFAST reactive dye to carry out first dyeing treatment for not less than 15 minutes, then adding calcium chloride to continue to carry out second dyeing treatment for not less than 5 minutes, then adding acetic acid and sodium acetate to continue to carry out third dyeing treatment for not less than 5 minutes, raising the temperature to 55-98 DEG C, and continuing to carry out fourth dyeing treatment for not less than 50 minutes; and the OWF of the ERIOFAST reactive dye is less than 1.0 percent. Therefore, under specific conditions, dyeing defects can be avoided while the nylon yarns are dyed with light colors.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a dyed nylon yarn, a preparation method thereof, and a textile product. Background technique [0002] Nylon is a polyamide fiber, which is the first synthetic fiber to appear in the world, also known as nylon. The emergence of nylon has brought a new look to textiles. Its synthesis is a major breakthrough in the synthetic fiber industry and a very important milestone in polymer chemistry. Nylon fabric has a wide range of applications and has excellent wear resistance, stretch elastic recovery, strength, dust resistance and antifouling properties. Its wear resistance is 10 times higher than cotton and 20 times higher than wool, and its durability is extremely high. Excellent; when 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 of nylon is 1-2 times higher than that of cotton, ...
