Step (5) drafting: the carded sliver long term irregularity that comb and parallel cotton fibers prior to spinning is made into is higher, deviation of weight is larger, and the extended parallelization of fiber is poor, fiber alignment is disorderly, and most of fiber becomes crotch or case of bending, also there is fraction flock simultaneously, so, need the carded sliver to process ripe bar further through mixing in doubling step, to improve sliver quality, it is 18g/5m that ripe bar is produced quantitatively; The concrete technological parameter of mixing in doubling step is as follows: slubbing and and, and and radical be 5-8 root, ratch (in front * after *) is 56-60*52-54*56-60mm, and back zone drafting multiple is 1.8-2.0;
Two roads and and, and and radical be 5-8 root, ratch (in front * after *) is 56-60*52-54*56-60mm, and back zone drafting multiple is 1.8-2.0;
Extreme trace and and, and and radical be 6-8 root, ratch (in front * after *) is 56-60*52-54*56-60mm, and back zone drafting multiple is 1.3-1.5;
Step (6) rove: through step (5) and and after carry out rove, its parameter is: regular roving feeding is 4.0-6.0g/10m, and back zone drafting multiple is 1.15-1.35, and ratch (after front *) is 60-63*70-73mm, and roving twist factor is 70-85;
Step (7) spun yarn: carry out spun yarn process after rove and make cop, its parameter is: spun yarn actual number is 14.8-59tex, back zone drafting multiple is 1.1-1.3, ratch (* back zone, proparea) is 52-56*62-70mm, twist factor is 320-380, steel traveler is 6903, and ingot speed is 13000-16000r/min;
Step (8) winder: yarn defect removed further by the cop made by spinning process, obtains shaping bobbin, winder speed 500-1400m/min;
Step (9) yarn steaming: the object of yarn steaming is shaped by yarn, adopt low temperature to vacuumize high wet setting, its parameter is:
First circulating temperature is 40-50 DEG C, and negative pressure is 95-105mb, and the time is 50-75 minute.
3. the production method of a kind of fire resistance fibre blended yarn according to claim 2, is characterized in that: destatic lubricating fluid, comprises three kinds of finishes respectively: soap powder 1.0-1.4%, loose electric clever 4.2-5.2%, ammonium chloride 3.7-4.5%, water 86-91%.
