Embodiment 1

[0039] Such as Figure 1~2 Shown, jute yarn is spun with jute special-purpose rotor spinning equipment of the present invention, and raw material is quantitatively the jute cooked bar of 7.5g / m: adopt four roller double rubber ring drafting mechanism, the jute cooked bar in the cooked bar tube 2 Strip 1 enters the rear drafting zone through the nip between the rear top roller 3 and the rear roller 4, and then enters the middle drafting zone through the nip between the middle and rear top roller 5 and the middle and rear roller 6 for low-power drafting, and enters respectively Between the upper apron 9 set on the middle front rubber roller 7 and the lower apron 10 set on the middle front roller 8 (main drafting zone), the main drafting is carried out under the high-speed rotation of the front roller 12, and finally enters the front The front nip of top roller 11 and front roller 12, this process has finished the super large drafting of sliver. Wherein the drafting multiple of ...

Embodiment 2

[0041] Spin jute yarn with jute special-purpose rotor spinning equipment of the present invention, raw material is the jute cooked slivers that quantification is 9.5g / m: adopt four roller double rubber ring drafting mechanism, the jute cooked sliver 1 in the cooked cane tube 2 passes through The nip between rear top roller 3 and rear roller 4 enters the rear drafting zone, then passes through the nip between middle rear top roller 5 and middle rear roller 6 and enters the middle drafting zone for low-power drafting, and enters the middle Between the upper apron 9 on the front rubber roller 7 and the lower apron 10 set on the middle front roller 8 (main drafting area), the main drafting is carried out under the high-speed rotation of the front roller 12, and finally enters the front top roller 11 With the front jaw of front roller 12, this process has completed the super large drafting of the strands. Among them, the drafting multiple of the rear drafting zone is 5, the draftin...

Abstract

The invention relates to a special rotor spinning equipment for jute and its application. The special rotor spinning equipment for jute has a pair of drawing rollers, a yarn guide and a winding device, and includes sequentially arranged drafting mechanisms and active air suction and exhaust. type rotor device; the jute yarn spun by special jute rotor spinning equipment has a count of more than 30 public counts; jute cooked slivers first pass through the drafting mechanism for super-large drafting, and then are directly sucked into the high-speed rotating active The fiber is condensed and twisted in the rotor of the suction and exhaust type rotor device, and then the yarn is pulled out of the rotor by the yarn delivery roller pair and the yarn guide, and the yarn is wound into a cross bobbin by the winding roller . The special rotor spinning equipment for jute of the present invention spins jute with high rigidity, long length and large dispersion into high-count yarn, laying a good foundation for the broad market prospect of jute products in the future.

Description

technical field [0001] The invention belongs to the technical field of spinning equipment, and relates to a new type of rotor spinning equipment and its application, in particular to a special rotor spinning equipment for jute and its application. Special rotor spinning equipment for jute and its application in spinning jute yarn. Background technique [0002] As a natural polymer fiber with high domestic production, jute fiber has excellent characteristics such as cool and breathable, good antibacterial properties, high tensile strength, low price, and easy biodegradation. It has broad market prospects and considerable economic benefits. However, the length of its single fiber is very short, ranging from 1mm to 2.5mm, with an average length of 1.9mm, and it needs to be spun with bundled technical fibers. At present, the traditional jute spinning process is: raw hemp - soft hemp - stacking bin - head comb - second comb - drawing (three) - (roving) - spun yarn - winding - (s...
