A new processing method for colorful slub yarn

Abstract

The invention relates to a manufacturing method of novel colorful bunchy yarn. The method includes the steps of firstly, primary roving, to be more specific, sequentially performing blending, blowing, carding, drawing and roving on a first fiber bundle to obtain rough yarn A, sequentially performing blowing, carding and drawing of a second fiber bundle to obtain drawing yarn B, wherein at least one of the first fiber bundle and the second fiber bundle is the colored fiber bundle, and the twist factor in the roving process of the rough yarn A is 90-110; secondly, secondary roving, to be more specific, feeding to the rough yarn A and the drawing yarn B into a roving machine at the same time, and roving again, wherein the twist factor in the roving process is 110-125, a roving bobbin hanger is disposed at the rear position, corresponding to a slitting device, of the roving machine, and the horn-shaped opening of the roving machine is provided with a large hole and a small hole; thirdly, spinning, to be more specific, using a middle-rear roller acceleration bunchy yarn device to produce spun yarn with the rough yarn; fourthly, spooling, to be more specific, using a Savio automatic spooling electronic yarn clearer is used to make the spun yarn into spooled yarn.

Description

technical field [0001] The invention belongs to the technical field of textiles, and in particular relates to a processing method of a novel colorful slub yarn. Background technique [0002] According to the analysis of the development trend of China's color spinning industry from 2014 to 2019, the terminal clothing industry has entered the era of branding. Fashion, comfort, speed and environmental protection are the trends of clothing consumption. The emergence and development of color spinning just conform to this change. . Following the widespread application of color-spun yarn by international brands, domestic brand operators who have emerged in recent years and mainly engaged in casual clothing have also begun to use color-spun yarn as their processing raw materials in large quantities. With the accelerated expansion of the overall market capacity of color-spun yarn, It is also insufficient. One is that the brand differentiation is not enough, the product innovation i...

AI Technical Summary

Problems solved by technology

One is that the brand differentiation is not enough, the product innovation is insufficient, and the selling point is lacking

Second, products flock to low-end, and high-end development is insufficient

The fixed lengths of the two colors of rovings are different, so when changing the rovings in the spinning process, there will be more end yarns in the roving batch, resulting in great waste

In the spinning process, the number of rovings is double that of normal spinning, and the workload of changing rovings is doubled. The operation is cumbersome, and it is easy to form a single roving to feed people, resulting in quality accidents.

[0004] In order to solve these problems, a new type of fancy yarn is considered at the same time, so the principle of siro spinning is moved forward to the roving process. However, the following problems exist in the direct grafting method: the bell mouth of the roving drafting area is replaced by a single eye. After forming a double-eye bell mouth, it is directly fed by two drawing frames. After trial spinning, the effect of color overflow on the cloth surface is not obvious, the color mixing is uneven, and the cans behind the roving frame are doubled. The cans occupy a large area and are easy to operate. complex

Secondly, since the drafting ratio of the roving frame is generally 4.2-12.0 times, the quantity of the feeding drawing frame is too limited. If the drawing quantity is reduced, the drawing speed will be increased
