Problems solved by technology

When the temperature is higher than 90°C, the disperse dyes of ordinary polyester yarns are easy to migrate out and need to be removed by washing water. During the washing process, the woven labels are easily deformed and need to be ironed again; The molecular weight of the dye is large, and it is easy to dye flowers during the dyeing process, which increases the difficulty of dyeing; if polyester modified yarns (such as cationic dyeable yarns) are used, the structural characteristics of these yarns are easy to unravel, and it is necessary to increase the anti-unraveling oil. The agent will seep into white or light-colored clothes later, and it still needs to be washed to remove the oil on the woven label; Variety of colors, small quantity, special order in advance, this method is still expensive, and the cycle is long, which cannot meet the industry's rapid response requirements

preparation example Construction

[0040] A kind of preparation method of polyester woven label of the present invention comprises the following steps:

[0041] (1) warp pretreatment

[0042] The polyester warp yarn (white or inorganic salt colored polyester warp yarn) is treated with high temperature hot water at 125°C-145°C for 20-60min, the liquor ratio is 1:8-10, dehydrated, and then pre-dried at below 80°C until the moisture content is 10 ~30%, and then baked at 150-170°C for 5-10 minutes at high temperature to obtain;

[0043] (2) Selection of weft yarn

[0044] Select the weft yarn that meets the following conditions: Dye the polyester weft yarn at 125-135°C for 20-60 minutes, then reduce and wash it at 90-115°C for 1-3 times, and press at 115-125°C for 15-20 seconds to test the yarn Color fastness, color fastness greater than 4.0 is qualified;

[0045] (3) Flower writing: Perform the flower writing operation to obtain the flower writing data required for the production of woven labels. The flower wri...

Embodiment 1

[0067] A kind of preparation method of polyester woven label of the present embodiment comprises the following steps:

[0068] (1) Polyester warp yarn pretreatment: add 10 kg of 75D polyester black warp cheese into the high temperature and high pressure cheese dyeing machine; add 100L of water, add degreasing agent JintergeLCF-185, 80~150g, heat up to 130℃~145℃, Keep warm for 30-60 minutes, drain, dehydrate, pre-bake at below 80°C to a moisture content of 10-30%, then bake in an oven at 150-170°C for 5-10 minutes, and warp.

[0069] (2) Selection of weft yarn

[0070] Select the weft yarn that meets the following conditions: Dye the polyester weft yarn at a high temperature of 125-135°C for 30-60 minutes, then reduce and wash it at 90-115°C for 1-3 times, and press at 115-125°C for 15-20 seconds to test the yarn Line color fastness, color fastness greater than 4.0 is qualified.

[0071] (3) Flower writing: use flower writing software to write flowers, and obtain the loom com...

Abstract

The invention discloses a polyester woven label and a preparation method thereof. The preparation method includes following steps: (1), warp pretreatment; (2), weft selection; (3), pattern printing; (4), label weaving; (5), cutting and slitting. The polyester woven label made by the preparation method does not need to go through wash care and ironing processes, and the polyester woven label is less prone to wrinkling and contracting when being subjected to subsequent dyeing and wash care at 60-100 DEG C and press-ironing and drying at 100-160 DEG C. By using the preparation method, production period is shortened, production cost is lowered, fastness of the woven label in each aspect can be controlled at four or higher grade, and heat shrinkage rate of the woven label can be controlled below 3%.

Description

technical field [0001] The invention relates to the technical field of clothing accessories, in particular to a polyester woven label and a preparation method thereof. Background technique [0002] With the public's aesthetics and individualized development requirements, polyester woven labels need to be dyed, washed at 80-100°C, and dried at 80-100°C together with the garments, while polyester woven labels are 80-90°C higher than the vitrification temperature of polyester. ℃, it is easy to wrinkle and shrink. Woven labels that wrinkle and shrink will scratch human skin when worn, and shrinking woven labels will wrinkle clothes and affect the appearance of clothes. [0003] In order to improve this problem, the common practice is: when producing polyester woven labels, use a higher temperature of 160-180°C than the subsequent ones to press and shape. When the temperature is higher than 90°C, the disperse dyes of ordinary polyester yarns are easy to migrate out and need to ...
