Embodiment 1

[0030] Embodiment 1: Taking four rovings fed simultaneously on the TH558 four-roller, four-apron ultra-large draft ring spinning frame to produce 11.7tex segmented colored slub yarn as an example; one yellow roving and one A blue roving is fed from the rear roller through the double bell mouth, a red roving is fed from the middle rear roller through the yarn guide groove, and a white roving is fed from the middle front roller through the yarn guide groove.

[0031] The specific process steps are as follows:

[0032] (1) Cotton distribution:

[0033] Raw cotton: 100% Xinjiang long-staple cotton is selected, the main body length is 36.7mm, the micronaire value is 3.4, the short-staple rate is 11%, and the moisture regain is 7.1%.

[0034] (2) Open and clean cotton

[0035] FA106 cotton opener is adopted, the beater speed is 490r / min, the distance between the feeding roller and the beater is 10.5mm, the distance between the dust bar and the dust bar is 11mm, the entrance is 8.5...

Embodiment 2

[0050] Embodiment 2: Take four rovings fed simultaneously on the TH558 four-roller, four-apron ultra-large draft ring spinning machine to produce 11.7tex white yarn segment as an example of segmented colored slub yarn; one yellow roving and one A blue roving is fed from the rear roller through the double bell mouth, a red roving is fed from the middle rear roller through the yarn guide groove, and a white roving is fed from the middle front roller through the yarn guide groove.

[0051] The specific process steps are as follows:

[0052] (1) Cotton distribution:

[0053] Raw cotton: 100% Xinjiang long-staple cotton is selected, the main body length is 35.8mm, the micronaire value is 3.1, the short-staple rate is 10.5%, and the moisture regain is 7.2%.

[0054] (2) Open and clean cotton

[0055] FA106 cotton opener is adopted, the beater speed is 482r / min, the distance between the cotton feeding roller and the beater is 10mm, the distance between the dust bar and the dust bar...

Abstract

The invention discloses a method for spinning color segment bamboo joint color yarns. In the spun yarn process, four rovings with at least one color are simultaneously fed into a huge drafting spinning frame which is of a four-roller, four-leather-collar and three-area type. In the four rovings, two of the four rovings are fed in from rear rollers through double-horn openings, one roving is fed in from a middle-rear roller through a yarn guiding groove, and one roving is fed in from a middle-front roller through a yarn guiding groove. According to the method, the four-roving feeding scheme is adopted, the segment color effect with four different colors at most can be achieved, and the production of segment color yarns of different styles is achieved. In the part of the spun yarn process, the four-roller, four-leather-collar and three-area type is used so that huge drafting of 30-300 times can be achieved, a foundation is laid for simultaneous feeding of the four rovings, and spinning efficiency is improved. Meanwhile, the rear rollers, the middle-rear roller and the middle-front roller in the four rollers are controlled respectively through an independent servo motor, the draft multiple in the three-area drafting can be adjusted at will, so that the segment color bamboo joint effect of various styles is achieved, and the spinning adaptability and the spinning quality of segment color yarns are improved.

Description

technical field [0001] The invention relates to the new technology field of ring spinning, in particular to a method for spinning slub colored yarn with four rovings fed into super large draft color segment. Background technique [0002] Ring spinning, which achieves twisting through spindle rotation, is the most traditional spinning method, and it is also the most widely used and most common spinning method in the market. The technology is very mature. New spinning technologies, such as rotor spinning, air-jet spinning, etc., especially air-jet spinning, have completely changed the twisting mechanism of ring spinning by using high-speed swirling airflow to make fiber bundles false-twisted and wrapped into yarns, but these new spinning methods There is still no substitute for ring spinning in terms of raw material availability and overall yarn quality. Therefore, ring spinning is still the most important method of spun yarn production. The production of high-quality spun y...
