Embodiment 1

[0021] 1. Hang a batch of silk tubes on the wire frame in sequence, record the sequence number, and enter the circular loom in sequence;

[0022] 2. The large circular machine is woven into a large circular machine cloth of 3 meters, and the cloth to be inspected including all the original silk routes is taken with a knitted cloth sampler;

[0023] 3. Wash the cloth to be inspected in step 2 with neutral soap powder and then dehydrate it for use;

[0024] 4. Weigh the dye and dissolve it in water with an ultrasonic oscillator to form a dyeing solution for later use. The weight ratio of the dye to the cloth sample to be inspected is 0.03% of the red dye, 0.21% of the yellow dye, and 0.03% of the blue dye;

[0025] 5. Dilute the dyeing solution in step 4 with water in the dyeing machine, the weight ratio of the cloth to be inspected and the water in the dyeing machine is 1:40, add "Pingpingjiao" which accounts for 0.6% of the cloth sample to be inspected, heat up and stir evenly...

Embodiment 2

[0031] Adopt the step of embodiment 1 to discriminate silk thread dyeing property, difference is,

[0032] Step 4. Dissolve the dye in water with an ultrasonic oscillator to form a dyeing solution for later use. The weight ratio of the dye to the cloth sample to be inspected is 0.09% of the red dye, 0.55% of the yellow dye, and 0.86% of the blue dye;

[0033] 5. Put the dyeing solution in step 4 into the dyeing machine and dilute it with water. The weight ratio of the cloth to be inspected and the water in the dyeing machine is 1:50. ;

[0034] 6. At 40°C, add the cloth to be inspected in step 3 into the dye vat and stir continuously;

[0035] 7. The heating rate is controlled at about 2°C / min, raised to 100°C and kept for 45 minutes, then cooled to 35°C to complete the dyeing;

Embodiment 3

[0037] Adopt the step of embodiment 1 to discriminate silk thread dyeing property, difference is,

[0038] Step 4, weigh the dye and dissolve it in water with an ultrasonic oscillator to form a dyeing solution for later use. The weight ratio of the dye to the cloth sample to be inspected is 0.06% of the red dye, 0.35% of the yellow dye, and 0.53% of the blue dye;

[0039] 5. Dilute the dyeing solution in step 4 with water in the dyeing machine, the weight ratio of the cloth to be inspected and the water in the dyeing machine is 1:35, add "Pingpingjiao" which accounts for 0.8% of the cloth sample to be inspected, heat up and stir evenly ;

[0040] 6. At 40°C, add the cloth to be inspected in step 3 into the dye vat and stir continuously;

[0041] 7. Control the heating rate at about 1.5°C / min, rise to 100°C and keep for 40 minutes, then cool down to 35°C to complete the dyeing.

[0042] In addition, it is preferred to replace the red dye, yellow dye, and blue dye in Embodimen...

Abstract

The invention discloses a method for comprehensively determines the dyeing performance of silk threads by large circular knitting and dyeing detection and 'three matching color' dyeing detection. Thus, the accuracy and reliability of the determination of the dyeing performance of the silk threads are improved greatly.

Description

technical field [0001] The invention relates to a method for judging the dyeing performance of silk threads. Background technique [0002] At present, in the high-speed spinning and texturing production process of polycaprolactam, in the process control and product quality inspection of filament and elastic yarn, it is very important to control the dyeing uniformity of fiber products. The conventional control method is In the production process of the product, a certain scale of sample silk is drawn or the factory inspection is a full batch of each bobbin. On a single-feeding circular knitting machine, the sample silk is sequentially woven into a 5cm-long sock tube and passed through " pre-treatment", and then dyed with neutral gray 2BL dye and dried in D 65 Under the light source, compare the gray card, and evaluate the coloring uniformity of the dyed sample with eyes and rate it. But now this traditional method is no longer suitable for the high-quality standard requirem...
