Embodiment 1

[0025] A polyester sewing thread dyeing process, its operation method comprises the following steps:

[0026] A. The polyester slices are spun into cotton-like short fibers, which are rolled into rovings after cleaning, and further drawn into spun yarns. The spun yarns are twisted and plied to make raw white sewing thread yarns;

[0027] B. Weigh the white sewing thread yarn, measure and calculate the dye content of the standard color when the white sewing thread yarn has not faded, measure and calculate the dye weight of the white sewing thread yarn that has faded color, and compare the white sewing thread with the color card comparison method. Compare the faded part of the yarn with the non-faded part, and calculate the faded color;

[0028] C. Fully mix and precipitate the pre-prepared dyeing agent, and then carry out dyeing processing. The temperature during spraying is 230°C, and the steam dyeing fixation temperature is 350°C; the spraying time is completed within 10 minu...

Embodiment 2

[0031] In embodiment one, add following operation again:

[0032] In step B, according to the principle of how much fading, light, medium and dark dyes with corresponding weights can be obtained; the amount of spray dyeing auxiliaries is 18 times the normal amount of water dyeing method. The amount of various additives, adjust the bath ratio, dissolve the dye and additives in 60°C water, stir well, heat the dye to 260°C, when the pressure reaches 0.2 MPa, turn on the air pump to inflate, and wait for the pressure to increase When it reaches 0.6 MPa, spray dye the various parts of the sewing thread yarn until it is saturated, preferably without dripping the dye solution.

[0033] A polyester sewing thread dyeing process, its operation method comprises the following steps:

[0034] A. The polyester slices are spun into cotton-like short fibers, which are rolled into rovings after cleaning, and further drawn into spun yarns. The spun yarns are twisted and plied to make raw white...

Embodiment 3

[0039] In embodiment two, add following operation again:

[0040] The dyeing raw materials in step C are acid green lotus (purple) 4BNS.3BR60, FBL, acid bright yellow G.20, weak acid yellow 20, 3cs, chai lin red B, acid fuchsin 6B, acid red XB, weak (Pula) Brilliant red B, 10:E.3B-E specific composition, auxiliary formula consists of acetic acid, sulfuric acid, leveling agent, penetrating agent.

[0041] A polyester sewing thread dyeing process, its operation method comprises the following steps:

[0042] A. The polyester slices are spun into cotton-like short fibers, which are rolled into rovings after cleaning, and further drawn into spun yarns. The spun yarns are twisted and plied to make raw white sewing thread yarns;

[0043] B. Weigh the white sewing thread yarn, measure and calculate the dye content of the standard color when the white sewing thread yarn has not faded, measure and calculate the dye weight of the white sewing thread yarn that has faded color, and compare ...

Abstract

The invention discloses a polyester fiber sewing thread dyeing process and a device thereof. The device comprises a machine body, a dyeing box is fixedly mounted at the bottom of the left side of themachine body, a first conveying roller is movably mounted at the portion, corresponding to a yarn feeding position, of the left side of an inner cavity of the machine body, and a second conveying roller is movably mounted on the right side of the first conveying roller; third conveying rollers are movably mounted on the top of the inner cavity of the machine body and symmetrically arranged on an upper row and a lower row. Through improvement of a traditional dyeing process, dyeing processing can be carried out according to color fading standards of yarn to ensure the dyeing uniformity when theyarn is dyed, the quality of the processed polyester yarn is better, the processed polyester yarn is rich in variety, and the process and the device thereof are suitable for developing new products.All-directional drying treatment can be carried out on the yarn after dyeing, the production efficiency of the yarn is improved, and meanwhile the problem is solved that the textile processing qualityin the later period is directly affected due to an uneven dyeing problem during dyeing.

Description

technical field [0001] The invention relates to the technical field of textile processing, in particular to a polyester sewing thread dyeing process and a device thereof. Background technique [0002] Sewing thread is the thread required for knitted clothing products. According to raw materials, sewing thread can be divided into three categories: natural fiber, synthetic fiber sewing thread and mixed sewing thread. With the development of polyester industry, sewing thread uses pure polyester fiber as its raw material. More and more, polyester fiber is a kind of high-quality synthetic fiber, which is used to make sutures with high strength. Reduce the strength, its shrinkage rate is very small, shrinkage is less than 1% after proper shaping, so the stitches sewn can always remain flat and beautiful, no shrinkage, wear resistance is second only to nylon, low moisture regain, good High temperature resistance, low temperature resistance, light resistance and water resistance. T...
