Below in conjunction with the specific embodiment the present invention is further described, embodiment of the present invention is not limited to following embodiment, and the various variations of under the prerequisite that does not break away from aim of the present invention, making all belong within protection scope of the present invention.
The specific embodiment
Embodiment one.Wool, PTT and cashmere blended knitting yarn, this stocking yarn is the stocking yarn of 16.8dtex, contains wool 75%, PTT20% and cashmere 5%.
Said wool be 100S Australia hair from sliver, fibre fineness: 16.5Mic; Fibre length: 80mm; The following undercoat coefficient of 20mm＜3% wherein.The Mic value is positive mic value, is an important indicator of reflection cotton fiber inherent quality, mainly tests the maturity of cotton fiber and has functional relation with the cotton fiber fineness.The Mic value has been listed the GB1103-1999 national standard in, as one of check cotton grade important indicator.
Said PTT is that polytrimethylene terephthalate (Polytrimethyleneterephthalate) is by terephthalic acid (TPA) (TPA) and 1, and ammediol (PDO) is a kind of polyester fiber through the polymer that esterifying polycondensation forms.Ptt fiber has the characteristic of terylene, polyamide fibre, acrylic fibers concurrently, except that antifouling property well, be easy to dyeing, soft, high resilience in addition, extensibility is equally good with spandex fibre, compares with the elastomer spandex to be easier to processing, is fit to very much the textile garment lining; PTT also has characteristics such as dry and comfortable, well-pressed in addition.The optional PTT that produces with Shanghai Hua Yuan of PTT among the present invention, fibre fineness 1.38dtex, length 38mm; Because PTT is novel polyester fiber, it has the chemical fibre performance concurrently, and resistivity is high; Poorly conductive because friction is prone to produce static, therefore must spray with antistatic additive before the spinning aborning; Stacked 24 hours, and made the health processing before raw material is carried out spinning.
Described cashmere is selected 14.5～16 microns of average diameters for use, 35～45 millimeters of average fiber lengths, and about 17 kms of breaking length, stretched length reaches 3 times of natural lengths, and hygroscopicity is strong, and warmth retention property is fine.
The production technology of above-mentioned wool, PTT and cashmere blended knitting yarn, this technology comprise spin before antistatic processing, scutching cotton operation, carding step, mixing in doubling step, rove operation, spinning process, winding procedure and and twist with the fingers operation (being doubling, double twisting operation):
(1) spin before antistatic handle: because of wool, PTT, cashmere fiber has been prone to static, spinnability is relatively poor, so raw material is carried out the preliminary treatment of necessity before last machine, the main task of pretreatment process comprises oiling dewing and shredding, mixing, the removal of impurities of fiber.Above operation can adopt conventional antistatic to handle.
(2) scutching cotton operation: to wool, cashmere fiber contains assorted few, the characteristics of fiber easy damaged, cotton cleaning process principle: play soft shredding to comb generation; Promptly suitably slow down hired roughneck's speed of A036C, A092A and A076C, and corresponding raising fan speed guarantee the smooth delivery of power of cotton stream.Cotton rolling quantity 360g/m, fixed length 30.6m, lap roller rotating speed 10r/min.
(3) carding step: to the characteristics of high-n wool fiber; Adopt the technological principle of " light quantitatively, low velocity, space more greatly "; Produce static and cause that life is rough does for alleviating in carding process, Bearded-needle knitted cloth is selected the low highly dense card clothing of pin for use, to reduce fiber laydown; Be convenient to conversion, prevent to twine cylinder; Rare back was close before flat-clothing was arranged, to strengthen carding effect.Reduce the cylinder licker-in speed simultaneously, amplify spacing between cylinder and cover plate, licker-in and feed plate, increase the feed plate height and cut apart length, reduce fibre damage to increase feed plate technology.The comb and parallel cotton fibers prior to spinning main technologic parameters is following: licker-in rotating speed 650r/min; Cylinder rotating speed 280r/min, doffer's rotating speed 12.9r/min, 5 0.28mm that space, 0.25mm, 0.25mm, 0.25mm and 0.28mm of cylinder～cover plate; Licker-in～feed plate 0.3mm that spaces; Licker-in～cylinder 0.23mm that spaces, the cylinder～doffer 0.18mm that spaces, the carded sliver is done quantitative 18.5g/5m.
(4) mixing in doubling step: adopt to amplify space, the suitable technological principle of pressurization, low velocity.This operation should strict control workshop moisture temperature, to increase interfibrous boundling effect, prevents to twine roller, around the roller phenomenon.Adopt four road draftings, fully mix the resultant yarn no color differnece to guarantee fiber.Concrete technology such as following table:
(5) rove operation: still with extended parallelization, the separating degree of further raising fiber, the bar evenness that improves sliver is a principle, particularly will control Roving Elongation on Process configuration, prevents the dried deterioration of bar.For guaranteeing that bar is evenly dried, reduce details, the higher grasp of roving twist factor, not going out hardhead with the spinning-drafting process is principle, roving twist factor 115.Rove is done quantitative 4.5g/10m, 1.24 times of back zone drafting multiples, front roller rotating speed 180r/min, preceding middle roller centre-to-centre spacing 50mm, middle rear roller centre-to-centre spacing 60mm.
(6) spinning process: rationally match rings, steel traveler and replacing in time; The steel traveler of spun yarn should be laid particular stress on apolegamy, to reduce resultant yarn filoplume.Its main technologic parameters is following: 1.25 times of back zone drafting multiples, and 26.995 times of total draft multiples, ratch are 44 * 60mm, twist factor is 392.
(7) winding procedure: adopt SAVIO type fully-automatic spooling machine, rationally set the clear parameter of electricity, keep the bright and clean of yarn path, suitably reduce groove drum speed, to reduce the filoplume value of cheese.The clear setting value of electricity: short slub (S)+160% * 1.5cm; Long slubbing (L)+40% * 30cm; Long details (T)-30% * 20cm.
(8) and twist with the fingers operation (being doubling, double twisting operation): the double joint feeding is adopted in doubling, suitably reduces tension piece weight, in time cleans and flies hair in the tension pulley, and tension piece is rotated flexibly, reduces doubling speed, guarantees two one thread even tensions, avoids dividing sinker.The doubling speed controlling is at 700r/min.Two-for-one twister ingot speed is left 9000r/min, draws fast 17.6M/min, and two yarn twist factors are 294; For avoiding weak twist or tightly twist, double twisting adopts not joint of broken end replace tubes.
The Temperature and Humidity Control of each operation
Because the moisture pick-up properties of woollen and cashmere fiber is good, thus in spinning process, receive the influence of ambient temperature and humidity bigger, so we should the strict humiture of controlling each workshop.Shown in the Temperature and Humidity Control of each operation sees the following form.
The Temperature and Humidity Control table of each operation
