five, placing two reels of covering threads on the first covering spindle (6) and the second covering spindle (7), feeding the alloy filament and the covering threads into the upper roller (5), pulling the alloy filament and the covering threads by the lower roller (9), taking the alloy filament as a core wire, covering and twisting the alloy filament by using the covering threads, wherein breaking conditions of the alloy filament and the covered yarn are monitored in real time by the alloy filament break alarm (13) and the covered yarn break alarm (14), and an alarm is given when the breaking occurs, thus reminding workers to handle timely; and
six, conducting heat setting through a heat setting box (8) on the blending equipment after covering is completed, and finally winding through a winding device (10).
3. The alloy filament and simple yarn blending equipment and process according to claim 2, wherein the fore-spinning stage comprises the following steps:
(1) compressing: extruding the raw materials by an extruder to facilitate mixing;
(2) impurity removal: removing most impurities, defects, and fibrils unsuitable for spinning from the raw materials,
(3) lap forming of the yarns;
(4) combing;
and (5) drawing;
wherein the post-spinning stage comprises the following steps:
(1) roving: drafting and twisting a drawn sliver combined by drawing to enable the sliver to have a certain strength, thus facilitate winding of the rove and unwinding of the sliver on a spinning frame;
(2) spinning: drafting and attenuating the rove to the required fineness, and twisting to form spun yarn with a certain twist and strength, and winding the spun yarn on the bobbin.
4. The alloy filament and simple yarn blending equipment and process according to claim 3, wherein the drawing comprises the following steps:
a, combining 6-8 cotton slivers to improve the length unevenness of the cotton slivers;
b, elongating and attenuating the cotton slivers to a specified weight, and further improving the straightening parallelism degree of the fibers;
c, mixing the cotton slivers on a drawing frame;
and d, making coiled silvers into well-formed drawn slivers, and regularly putting the drawn slivers in a spinning machine in a coiled manner.
