It is highly preferred that in the 3rd step, technological principle of the three road mixing in doubling step using " big gauge, big pressurization, jogging speed ".
In above-mentioned three road mixing in doubling step, due to stainless steel fibre volume mass it is larger, to make bar dry and mixed effect is preferable,
The technique for three roads being adopted all for 8 and being closed, makes stainless steel fibre distribution more uniform, improves resultant yarn irregularity.Three road draftings are equal
Using less drafting multiple, be beneficial to the uniformity and strength for improving yarn, head and back area draft it is bigger than normal, three and back area draft
It is less, to reduce impact of the three road back area draft ripples to bar evenness, improve the quality of semi-products.Using the technique of big gauge
Principle, three road drafting drawing-offs make stainless steel fibre length further shorten, fibre length less than or equal to Lora grip away from.From hard
The larger rubber roll of degree, using larger pressurization, to improve the curable grip to yarn.Further, since stainless steel fibre fragility is larger,
Drafting motor speed is unsuitable excessive.
Preferably, in the 4th step, mixing rove is obtained using Roving Frames, in Roving Frames, using 81 degree of rubber rolls of Shao Er,
Regular roving feeding is 4-5g/10m, and total draft multiple is 6.8-8.5 times, and back zone drafting multiple is 1.33 times, and the twist is 300-320

The technological principle of jogging speed ".
In above-mentioned Roving Frames, be reduce spinning when drafting force, using lighter regular roving feeding, the less twist and compared with
Big roller gauge.To increase the curable grip of Lora, using the technological principle pressurizeed again.Using less back area draft with it is larger
Drawing-off gauge, with improve drafting back zone friction field be distributed, improve bar evenness.Further, since stainless steel fibre is crisp
Property it is larger, thick motor speed is unsuitable excessive.
Preferably, in the 5th step, cotton/rustless steel blending covering yarn is obtained using spinning process, in spinning process, four is adopted

It is highly preferred that in the 5th step, spinning process is using " the little twist, again little back area draft, pressurization, big gauge, at a slow speed
The technological principle of degree ".
In above-mentioned spinning process, as stainless steel fibre torsional modulus is larger, kink, brittle failure are also easy to produce, thus the twist is inclined
Little grasp.Using less back area draft and larger drawing-off gauge, it is distributed with the friction field for improving drafting back zone, improves bar
Evenness.Pressurization again improves Lora curable grip, and little back area draft and big gauge reduce drafting force, and curable grip is mutually fitted with drafting force
Should, it is ensured that spinning is smoothed out.Further, since stainless steel fibre fragility is larger, the preferably low grasp of spun yarn motor speed.
