The specific embodiment
Siro-spun yarn of the present invention is to make Siro-spun yarn by cotton leftover bits and pieces and viscose according to quantitatively carrying out blending than 7:3, and 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.
Its technological process:
The general network machine of 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 → 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, contains and mixes less, and opening picking mixes as main take shredding, adopts the technological principle of " more short flow process, comb less and beats, and receives less more, rolls less ".Because viscose regain is large, cohesive force is poor, static is serious, spinnability is poor, in the time of rolling unwinding, easily cause sticky volume, 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.Viscose glue is rolled up quantitative 375g/m, 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, below cotton 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.Scutching cotton adopts the technological principle of " duty is grabbed less and grabbed, and thinly feeds tip-tap, caducous fall " more, and preferably each several part Beater Speed, amplifies between dirt rod and dirt rod and space, cotton rolling quantity 400g/m, fixed length 38m.
(2) comb and parallel cotton fibers prior to spinning
1, processing 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, increase both speed ratios.Mote knife angle is 90 degree, card sweeps after sealing, and funnel and aspiration channel, reduce fibre damage, the carded sliver is done 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 ", the each position of reasonable disposition 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: for two kinds of fibers fully mix, reduce resultant yarn aberration, adopt three roads mixed also.Because of spun yarn and thick special yarn match doff, need feed with two light quantitative rove simultaneously, and fiber fluffy, cohesive force is poor.So and strip adoption is gently quantitative, it is mixed that also slubbing is quantitative, 17.9g/5m, and 5 slivers and 3 sticks also close, 8 times of total drafts, 1.7 times of back area drafts, mixed two also quantitative 17.5g/5m, 1.5 times of back area drafts, mixed three also quantitative 16.9g/5m, 8.8 times of total drafts, 1.35 times of back area drafts, 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 match network spinning process and produce, feeding strand spacing and horn mouth position, spacing is excessive, and the angle between two one ribbons is just larger, and single thread yarn is long, and it is large that tension force becomes, thereby cause 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, causes the strong obviously decline of resultant yarn list; Contrary spacing is too small, has lost the meaning of Siro-spun yarn.By repetition test, determine that rove feeding spacing is 4.27mm, adjust guide horn mouth position, make to feed yarn and be agglomerated into fine strip shape through gathering district in the middle of aspiration channel, be the key link that guarantees 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 considers 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 the order of PG14254 guiding principle, the cleaner 4.0mm that spaces, roller gauge 18*26mm, 1.25 times of back area drafts.
Implement after above-mentioned technology measure, obtain cotton leftover bits and pieces/viscose 70/30,36.4tex matches doff.This yarn and the tradition spinning with description are carried out to index contrast:
Result is as follows:
| Spinning system | Tradition is around spinning | Siro-spun yarn |
