Detailed description of the invention
Siro-spun yarn of the present invention is that its production method comprises the following steps: (1) opening picking (2) comb and parallel cotton fibers prior to spinning (3) drafting: (4) rove (5) spun yarn by cotton leftover bits and pieces and viscose according to quantitatively carrying out blending than 7:3 makes Siro-spun yarn.
Its technological process:
FA002 type griping cotton machine → A035 type cotton blender machine → FA106 type opener → FA045 type fibre-condensing machine → A076 type lapper → FA186 type carding machine → FA311 type drawing frame → drafting (three roads) → FA491 type Speed frames → general network machine of FA502 fine spining machine → 014D type
Aforementioned production method specifically comprises the following steps:
(1) opening picking
1, viscose fineness 1.52dtex, length 38mm, moisture regain 13%; Because viscose length is longer, regularity is good, and containing assorted few, opening picking mixes based on shredding, adopts the technological principle of " short route, how comb is few is beaten, and receive falls less, few rolling ".Because viscose regain is large, cohesive force is poor, electrostatic is serious, spinnability is poor, sticky volume is easily caused when rolling unwinding, each portion Beater Speed is all lower slightly than cotton (week number) fiber, and changes the hired roughneck of FA106 type opener into kirschner beater by blade, improves degree of opening.Quantitative 375g/m rolled up by viscose glue, fixed length 30m, griping cotton machine Beater Speed 720r/min, opener Beater Speed 450r/min, comprehensive Beater Speed 850r/min, lap roller speed 11r/min.
2, cotton below leftover bits and pieces principal length 16mm, fineness 1.2dtex, short fiber content 52%, percentage of impurity 16.5%, due to cotton leftover bits and pieces poor quality, short fiber content is higher, length is short, percentage of impurity is high.The technological principle that scutching cotton adopts " duty is grabbed and grabbed less, thinly feeds tip-tap, caducous fall " more, preferred each several part Beater Speed, amplifies the spacer of dirt rod and dirt rod, cotton rolling quantity 400g/m, fixed length 38m.
(2) comb and parallel cotton fibers prior to spinning
1, process viscose adopt " low velocity, in space, light quantitatively, strong point of comb " technological principle, suitably amplify spacing between feed plate and licker-in.Reduce cylinder licker-in speed, both increases speed ratio.Mote knife angle is 90 degree, card sweeps after closing, and funnel and aspiration channel reduce fibre damage, the carded sliver does quantitative 16.5g/5m, cylinder speed 330r/min, cover plate speed 80mm/min, licker-in speed 800r/min, doffer speed 20r/min, cylinder and cover plate spacer 10*9*8*8*9.
2, processing fent, takes the technological principle of " tightly spacing, strong point of comb, many removal of impurities ", reasonable disposition each position speed, cylinder speed 360r/min, cover plate speed 170r/min, licker-in speed 920r/min, doffer speed 22r/min, other grasp less than normal of spacing, dry quantitative 19.5g/5m.
(3) drafting: in order to two kinds of fibers fully mix, reduces resultant yarn aberration, adopts three roads mixed also.Because of spun yarn and thick special yarn Siro Yarn, need feed with two more quantitative rove simultaneously, and fiber fluffy, cohesive force is poor.So also strip adoption is gently quantitative, mixed and slubbing quantitative, 17.9g/5m, 5 slivers and 3 sticks also close, total draft 8 times, back area draft 1.7 times, mixes two and quantitative 17.5g/5m, back area draft 1.5 times, mix three and quantitative 16.9g/5m, total draft 8.8 times, back area draft 1.35 times, each road roller gauge is 7*9*12mm.
(4) rove: adopt " tightly spacing, strong point of comb ", suitably strengthen roving twist factor, the technological principle of little back area draft, dry is quantitatively 3.88g/10m, roller gauge 7*21*26.5mm, twist factor 110, back zone drafting multiple 1.25.
(5) spun yarn: for reducing grade and the ton yarn amount of cotton, improve yarn quality.Choose SEILE textile explained hereafter, feeding strand spacing and horn mouth position, spacing is excessive, and the angle between two one ribbons is just comparatively large, and single thread yarn is long, and tension force becomes large, thus causes unexpected elongation, causes broken end.The random fluctuation of congruent point place twist balance simultaneously strengthens, and in resultant yarn, two fiber tensions are inconsistent, cause resultant yarn list obviously to decline by force; Contrary spacing is too small, loses the meaning of Siro-spun yarn.By repetition test, determine that rove feeding spacing is 4.27mm, adjustment guide horn mouth position, makes feeding yarn be agglomerated into fine strip shape through Nesting Zone in the middle of aspiration channel, is the key link ensureing yarn quality.
The selection of twist factor: because viscose cohesive force is poor, smooth, therefore the grasp bigger than normal of the twist factor of this yarn, consider that again A net leftover bits and pieces short fiber content is high, percentage of impurity is large, poor quality.The twist factor of mixed yarn that we are preferred is 400, and front roller speed 190r/min has selected PG14254 guiding principle to make, and cleaner spaces 4.0mm, roller gauge 18*26mm, back area draft 1.25 times.
After implementing above-mentioned technology measure, obtain cotton leftover bits and pieces/viscose 70/30,36.4tex Siro Yarn.This yarn is spinned with the tradition with description and carries out index contrast:
Result is as follows:
| Spinning system | Tradition is around spinning | Siro-spun yarn |
| To distribute cotton grade/level | 6 | Cotton leftover bits and pieces |
| Short fiber content % | 20 | 50 |
| End breakage rate/root during thousand ingots | 15 | 6 |
