Problems solved by technology

The problem with this method is that during the soft treatment in the dyeing vat, the bath ratio is large and the waste is large. When the yarn is dried, due to the high temperature, some chemical materials such as softeners will volatilize with the increase of temperature, resulting in dyeing. The color of the yarn changes, especially the white and light-colored yellowing becomes more serious, and there are often disadvantages such as softness, unevenness, and sizing yarn stripping
Moreover, the process is long, the production cost is high, and the amount of chemical materials such as slurry and softener is high. The actual effective utilization rate is only 30%, and the rest is discharged with the waste liquid, which not only causes environmental pollution but also causes serious loss and waste.

Embodiment 1

[0025] Such as figure 1 As shown, it is a one-step process flow chart of the yarn winding chemical finishing process before weaving. The yarn 1 is installed with an oil tank in front of the tension regulator 5 between the yarn guide to the yarn shaft 8, yarn clearing and winding. 3. A guide roller 2 with a motor 4 is installed in the oil tank 3, and a far-infrared drying device 7 is added behind the yarn breaking and clearing sensor 6.

[0026] The yarn is the yarn spun from natural cellulose fibers, and the chemical materials used in softening, sizing, waxing and smoothing chemical finishing process are composed of 20 parts of softening agent, 30 parts of sizing agent, 30 parts of textile wax, smoothing agent 5 parts, 15 parts of diluent. Add the weighed chemical materials into the oil tank 3 after compounding;

[0027] The softness, sizing, waxing and smoothing chemical finishing process of the yarn spun from natural cellulose fiber is completed in the winding process afte...

Embodiment 2

[0035] The yarn is chemical fiber filament, soft, antistatic, and smooth. The composition of chemical materials used in the chemical finishing process is: 25 parts of softening agent, 25 parts of antistatic agent, 5 parts of smoothing agent, and 45 parts of thinner.

[0036] The chemical fiber filament is soft, antistatic, and smooth. The line speed of the chemical finishing process is 15 m / s, the temperature is 20 ° C, and the relative humidity is 75%; the far-infrared drying device is closed in the process 1-6; other processes are the same as in Example 1 .

Embodiment 3

[0038] Yarns blended with natural cellulose fibers and chemical fibers, softening, sizing, waxing, antistatic chemical finishing process chemical materials used in percent by weight: 20 parts of softening agent, 25 parts of textile wax, 5 parts of smoothing agent, antistatic 7 parts of agent, 30 parts of sizing agent, 13 parts of thinner.

[0039] The yarn of natural cellulose fiber and chemical fiber blending, the line speed of softness, antistatic, waxing, sizing finishing is 10 m / s, temperature 20 ℃, relative humidity 70%, other processes are the same as embodiment 1.

Abstract

The invention discloses a one-step finishing chemical finishing craft in cheese winding course after yarn dyeing and drying, which comprises the following steps: weighting chemical material in weight matching; building chemical material and then entering oil groove; putting chesses winded yarn in oil groove to coil yarn round the guide roller by motor; steeping yarn in chemical material; finishing drenching craft of chemical finishing after yarn absorbing liquid of chemical material; adjusting tension by tension adjuster; squeezing out surplus chemical material; coiling squeezed yarn round yarn roll by yarn break, clearing yarn with clearing yarn inducer, drying with far-infrared drying device.

Description

Technical field: [0001] The invention relates to a one-step method for finishing the yarn winding chemical finishing process before weaving, in particular to a one-step finishing method for the yarn winding, sizing, waxing, softening, antistatic and other chemical finishing processes before weaving. Background technique: [0002] Yarn dyeing is a necessary process for the production of all yarn-dyed textile products, and after dyeing, all textile yarns have factors that are not conducive to product production and processing, such as strength reduction, hairiness increase, and evenness deterioration. Therefore, both dyed and undyed yarns need chemical finishing such as winding, sizing, waxing, softness, and antistatic before weaving. The traditional method is to use yarn dyeing, softening treatment in the dye vat, dehydration and drying, and then antistatic, sizing and waxing treatments in the preparation process before weaving. The problem with this method is that during th...
