When cashmere is carried out scutching cotton, 100% combing sliver and cashmere bar dry weight weighed according to the 9:1 ratio tear up the back and evenly mix.Mixed raw materials is fed on the defeated cotton curtain of A092 cotton feeder, because raw material is not an individualized, raw material is through after shaking hopper, stop up at brad roller place, manually raw material is torn a part, again feed at defeated cotton curtain, become individualized rolling once more after the feeding again again, make the cotton silver mixing of sheep through raw material behind the comprehensive hired roughneck of A076C lapper; Yarn is long with cashmere bar length when blowing mixes, regularity good, it is assorted not contain, so the principle that opening and cleaning step is taked tip-tap, do not fallen, how pine is few is beaten, combs more and lack to fall.Because the cashmere fiber brute force is lower, for reducing fibre damage and hired roughneck's lap-ups, cause too much cotton knot, the comprehensive hired roughneck's speed of A076C lapper is adjusted to 703r/min by 938r/min, gives full play to the mixed stepless action of hopper.In order to prevent sticking volume, suitably strengthen cotton lap pressure simultaneously.Workshop relative humidity is 77%.
2, respectively cashmere and cotton are carried out carding step
When cashmere is carried out comb and parallel cotton fibers prior to spinning, the comb and parallel cotton fibers prior to spinning scheduling of production is on A186G frequency conversion carding machine, for reducing fibre damage, fiber is shifted smoothly, reduce cotton knot, except that using lower doffer speed 12.0r/min, cylinder speed drops to 299r/min by 337r/min, and licker-in speed drops to 618 r/min by 755r/min.Space on the car and adopt the pure technology of washing, it is 12,10,10,10,12 that cylinder spaces to cover plate.The platform card clothing model of starting shooting as follows: the Bearded-needle knitted cloth model is that AC2525*01550, density are 860 tooth/square inches; The doff clothing model is that AD4030*01880, density are 448 tooth/square inches; The taker-in clothing model be AT5810*05011, tooth close be 40 tooth/square inches; The flat-clothing model is that MCH-24, density are 240 tooth/square inches.In order to reduce noil, the car tripe uses mesh to leak the end after the comb and parallel cotton fibers prior to spinning, and import is spaced and is put into 12.0mm, and feed plate is raised 6mm, and workshop relative humidity is 55%.
Comb and parallel cotton fibers prior to spinning noil situation such as following table 2:
3-1, in advance also, comb and parallel cotton fibers prior to spinning then
For strengthening combing sliver and the quantitative control of cashmere bar, increase the pre-and technology of combing sliver and cashmere bar.Adopt the cotton silver mixings of 3 sheep and 3 cotton yarns to carry out and close, regulate the cotton silver mixing of sheep and the ratio of cotton yarn and then the blending rate of adjusting yarn in this step; Produce at the FA311A drawing frame, it is more normal to use the carbon black roller to drive, and back subsequently two grades of rollers have sticking flower phenomenon, are replaced by 980 rollers, and for guaranteeing to mix, the drafting air draught drops to minimum, reduces fiber loss.
3, mixing in doubling step
Produce at the FA311A drawing frame, it is more normal to use the carbon black roller to drive, and back subsequently two grades of rollers have sticking flower phenomenon, are replaced by 980 rollers, and for guaranteeing to mix, the drafting air draught drops to minimum, reduces fiber loss.Mixing also, 6 number of doubling of process using prevent generation of static electricity to reduce the strip friction.Front roller linear velocity speed drops to 120 meters/minute, and workshop relative humidity is 50.0%.Because three road weight CV% fluctuation is bigger, increases by one drafting and reduce weight CV%.
4, rove operation
The rove roller gauge is 14.5*28.5*37.5mm, for avoiding rove in coiling and unwinding process, to produce excessive accident elongation, guaranteeing that spun yarn does not go out under the situation of " hardhead ", roving twist factor suitably is increased to 93.5, drags tension force when reducing the rove unwinding.Workshop relative humidity is 53%.
Before spin the semi-products qualitative data and gather as following table 3:
5, spinning process
Spun yarn is put down at FA506S type fine spining machine and is led production, and the spun yarn board has carried out complete machine before driving; Concrete complete machine content comprises: roller and roller gauge before, during and after the school; Transfer the reel cage third gear to space, guarantee that jaw is concordant; Do reel cage pressure, the repetition measurement gross pressure meter reading 0.075Pa grade pressure 160cN that goes forward that gets off; Before getting on the bus, the new film spring, guarantees every chassis new film spring pressure unanimity by only checking; The askew spindle in school, askew air ring.It is more to break end on the car after driving, and with steel traveler FO 14/0, it is normal to drive.The technology roller gauge is 18*40 on the car, and rings is PG1 3854, and ingot speed is 14180r/min, and the design twist factor is 359, front roller speed 158 r/min, and last pin is the iron pin of going up.The resultant yarn data are counted the stocking yarn kind with textile jack per line and are compared, though the twist is big more than 3%, and single thread force and 100% long-staple cotton stocking yarn ratio low 10%.
The resultant yarn data gather following table 4:
6, winding procedure:
Winder is arranged to produce on the sharp peace of the network type, and the speed of a motor vehicle is 1000m/min, and it is that 590L beats and connects device that the winder joint has used, and twists with the fingers by force than more than 88.0%, and parameter is as follows clearly for electricity:
