Problems solved by technology

However, because air-jet vortex spinning uses high-speed compressed air to form yarns, the temperature and humidity environment is more demanding than general spinning. The relative humidity is controlled below 40%, which limits further development in product development
In the dyed weaving industry, the conventional process of dyed weaving is to weave after dyeing, and in the dyeing process, because the vinylon dissolution in the hollow yarn will directly affect the strength of the yarn, and then affect the processing of the subsequent process, so it cannot Large-scale application in the yarn-dyed industry

Embodiment 1

[0019] The preparation method of the vortex spinning colored hollow yarn in this embodiment comprises four steps of raw sliver preparation, pre-drawing, drawing and vortex spinning, and the specific steps are as follows:

[0020] (1) Raw sliver preparation: put the colored viscose fiber and natural color vinylon into the cotton mixing device for mechanical mixing, and make viscose fiber raw sliver and vinylon raw sliver of equal gram weight.

[0021] Among them, the mechanical mixing treatment refers to the opening process. Specifically, the viscose fiber is opened for the first time or called pre-opening. The pre-opening is carried out in the cotton mixing device. For the structure of the cotton mixing device, see figure 1 and figure 2 , the beater speed of the cotton mixing device is controlled at 740r / min, and then the second opening or deep opening is performed in the cotton opener (model FA006), and the beater speed of the cotton opener is controlled at 450r / min; Vinylon...

Embodiment 2

[0027] The working principle and process of this embodiment are the same as those in Embodiment 1, the difference being:

[0028](1) Raw sliver preparation: in the pre-opening of viscose fiber, the beater speed of the cotton mixing device is controlled at 650r / min; in the deep opening, the beater speed of the cotton opener is controlled at 460r / min; The beating speed of the cotton machine is controlled at 460r / min, and the vinylon and viscose fibers are sent to the carding machine after being loosened. Roll speed 940 rpm, delivery speed 100 m / min, cylinder-flat gauge 10 / 8.8 / 8.5 / 8.5, rear pre-opening gauge 18 / 17 / 16 / 16, front fixed carding The gauge is 10, the gap between the entrance and the outlet of the large drain bottom is 3 mm, and the exit is 0.8 mm, forming viscose fiber raw sliver and vinylon raw sliver respectively.

[0029] (2) Pre-drawing: The natural color vinylon raw sliver and viscose fiber raw sliver are drawn twice to obtain vinylon sliver and viscose fiber sli...

Embodiment 3

[0033] The working principle and process of this embodiment are the same as those in Embodiment 1, the difference being:

[0034] (1) Raw sliver preparation: in the pre-opening of viscose fiber, the beater speed of the cotton mixing device is controlled at 850r / min; in the deep opening, the beater speed of the cotton opener is controlled at 380r / min; The beating speed of the cotton machine is controlled at 380r / min, and the vinylon and viscose fibers are sent to the carding machine after opening. In the carding machine, the carding speed is controlled at 140m / min, the cylinder speed is 450 rpm, Roll speed 1160 rpm, delivery speed 80m / min, cylinder-flat gauge 10 / 9 / 8.8 / 8.8, rear pre-carding gauge 18 / 16 / 16 / 16, front fixed carding gauge The gap is 14, the gap between the entrance and the outlet is 0.4mm, and the gap between the bottom and the bottom is 5mm, forming viscose fiber raw sliver and vinylon raw sliver respectively.

[0035] (2) Pre-drawing: The natural color vinylon ra...

Abstract

The invention relates to a production method of vortex spun colored hollow yarns and belongs to the technical field of production of special yarns. Colored viscose fiber and natural vinylon are respectively mechanically mixed in a cotton mixer and made into viscose card slivers and vinylon card slivers equal in gram weight; the viscose card slivers and the vinylon card slivers are respectively double-drawn to obtain vinylon slivers and viscose slivers; the vinylon slivers are put in the middle, the viscose slivers are put among the vinylon slivers, and drawing is performed; vortex spinning is performed at low speed of 280-370m / min, with the draft ratio of 180-270 and feed ratio of 0.7-1.2, which increase cohesive force, and auxiliary draft ratio of 1.5-4 and back draft zone ratio of 2-7 are adopted. The hollow yarns obtained according to the technical scheme have the advantages that the defect that the vortex spun fabric is hard to touch is overcome, breathability of the yarns is improved, and the yarns are well drapable and applicable to clothing fabrics such as jean, dyed yarns and color-stripe fabric.

Description

technical field [0001] The invention relates to a preparation method of vortex spinning colored hollow yarn, which belongs to the technical field of special yarn preparation. Background technique [0002] Air-jet vortex spinning is a new spinning method that has emerged in recent years. Due to the high-speed compressed air spinning, there are high requirements for the characteristics of the fibers. Due to the wrapped yarn structure, the yarn is relatively hard, which affects the yarn quality. line of application. [0003] With the development of textile technology, different spinning forms can form different yarn styles due to different spinning principles. The vortex spinning process is short and the production rate is high. At the same time, it can save a lot of labor and is easy to operate. It is also relatively simple, and the strength and uniformity of the spun yarn are better than those of conventional technology. Not only can core-spun yarns be produced, but also dou...
