Embodiment 1

[0038] Embodiment 1: to produce 6.47tex (90 S ) colorful yarn as an example. Raw cotton: Xinjiang long-staple cotton with a fineness of 1.44dtex, a main body length of 38.2mm, a short staple rate of less than 20mm of 4.4%, a breaking strength of 24.4cN / tex, a breaking elongation of 7.7%, a micronaire value of 3.4, and a uniformity of 78.1%.

[0039] The specific process steps are as follows:

[0040] (1) Pretreatment

[0041] For the A roving, dye the long-staple cotton fiber yellow and let it stand for 20 hours; for the C roving, dye the long-staple cotton fiber green and let it stand for 20 hours.

[0042] (2) Open and clean cotton

[0043] For A roving, the speed of the beater is 780r / min, the distance of the beater blade extending from the rib is 2.5mm, and the annular sawtooth form of the beater is adopted, which is densely distributed on the outside and thin on the inside; The interval is 11mm, the distance between the dust bar and the beater is 8mm at the entrance, ...

Abstract

The invention discloses a four-roller three-thick-yarn feeding full compact spinning device which comprises four groups of drafting roller pairs. A distance-adjustable three-flared-opening feeding unit is additionally arranged at a position of the yarn guide rod of a back roller; a mechanical magnetic collector is additionally arranged on the back roller; a middle-rear roller is a narrow groove type positive pressure hollow roller; the jaw portion of the middle-rear roller is additionally provided with a separating roller unit; a front-middle roller is a narrow groove type negative pressure hollow roller; a front roller is a large-diameter narrow groove type negative pressure hollow roller. A yarn spinning method utilizing the four-roller three-thick-yarn feeding full compact spinning device comprises feeding three thick yarn of A thick yarn, B thick yarn and C thick yarn through the distance-adjustable three-flared-opening feeding unit in a spinning process from the rear roller, and obtaining needed yarn through four-roller-and-three-section draft. According to the four-roller three-thick-yarn feeding full compact spinning device, the total draft multiple can be improved to more than 300 times to the maximum, accordingly the simultaneous feeding of three kinds of thick yarn of an ordinary fixed quantity for spinning can be achieved, and the spinning efficiency can be effectively improved. Besides, high-quality color yarn can be provided.

Description

technical field [0001] The invention relates to the new technology field of ring spinning, in particular to a four-roller three-rove feeding fully concentrated spinning device, a three-rove feeding four-roller super-large draft colorful yarn and a production method thereof. Background technique [0002] With the development of social economy and the improvement of people's living standards, people's consumption concepts are constantly updated, and they pay more and more attention to the quality of life and living environment. The functional requirements of clothing are getting higher and higher, especially for clothing antibacterial, The requirements for health care, feel, quality and other aspects are constantly improving. On the other hand, with the continuous increase of market competition and the gradual increase of investment in the structural adjustment of my country's textile industry, in order to improve the added value of products and market competitiveness, yarn va...
