The specific embodiment
The present invention relates to a kind of revolving cup and spin diversification fiber yarn production method, it comprises following technical process: the fine dyeing → wool blending step → combing operation → mixing in doubling step → revolving cup that looses spins operation → doubling operation → double twisting operation, spins in the operation at said revolving cup; Ribbon flows to combing roller through fed agency, under the effect of card clothing on the combing roller, ribbon is carded to once more the fibre stream of filament shape; Filament stream is under the effect of combing roller centrifugal force and negative pressure air; From the pin tooth of combing roller break away from and under the effect of negative pressure air the entering rotor, rotor is the parts of high speed rotary, after filament flows into rotor; Under its action of centrifugal force, get into collection surface; Filament is assembled and in the form of a ring once more, under the effect of seed yarn and twister, formed yarn, the pin tooth density of said combing roller is 125 ~ 210 tooth/square inches; The collection surface of said rotor is the U type, and the rotor inwall of said U type collection surface and U type collection surface both sides is arc transition.
Said combing roller rotating speed is 5000 ~ 9000r/min, and said yarning cup speed is 30000 ~ 150000r/min.
Collection surface changes the U type into by original V-type, has not only increased the cubical content of collection surface, and has improved the binding force (cohesive force) to fiber, makes rotor spinning can be applicable to other diversification fibers (like fiber crops, silk, hair, chemical fibre etc.) except that cotton.
When rotor spinning is used for cotton spinning; For cotton knot that cotton is mixed is discharged, so the pin tooth density of combing roller is bigger, is generally 325 tooth/square inches; When revolving cup spins when being used for the diversification fiber spinning; Pin tooth density is excessive to cause damage to fiber easily, influences the quality of final yarns, therefore the pin tooth density of combing roller is changed into 125 ~ 210 tooth/square inches.
Revolving cup spins diversification fiber yarn and the contrast of RING SPINNING diversification fiber yarn:
The rotor spinning line structure: so-called yarn texture is arrangement or geometry and the line density of fiber in yarn, refers to specifically whether the axial direction fibre at yarn stretches, parallel, and whether radial fiber moves.Arrive through microscopic examination, no matter the rotor spinning line all has very big difference with RING SPINNING axially or radially.The rotor spinning line is in when twisting, and the twist is successively to transmit completion from the inside of yarn to the outer surface of yarn, that is to say that fiber is from inside to outside along yam axis spin rotation, winding.Ring spinning line spins just the opposite in when twisting and revolving cup.
The opposing parallel degree of fiber in the rotor spinning line, degree of stretching is than ring spinning line difference relatively, thus in the rotor spinning line radial migration amount of fiber less than ring spinning line.
1, yarn evenness: in the rotor spinning line process, combing roller produces carding role once more to yarn, makes that the separating degree of fiber is good, becomes sliver to do relatively evenly.Same kind, do the CV% value than ring spinning line low 8% ~ 10% with the Ubbelohde bar of number rotor spinning line.The colour mixture that can effectively solve simultaneously RING SPINNING diversification fiber yarn is irregular, the problem of incomplete mixing between fiber.
2, yarn defect number: because revolving cup has trash discharging apparatus in spinning, add the effect of combing roller, so the cotton knot in the rotor spinning line (card nailing neps), magazine lack 25% ~ 35% than RING SPINNING.Can effectively solve the problem of look grain, card nailing neps in the RING SPINNING diversification fiber yarn.Can effectively solve the problem that RING SPINNING diversification fiber yarn must use high price raw materials such as combed cotton besides.
3, the brute force of yarn: because the bar of rotor spinning line is done the CV% value better, mixture homogeneity is better between fiber.Think joint, the replace tubes joint of rotor spinning line are less than RING SPINNING greatly.So the powerful CV% value of yarn breakage is better than ring spinning line far away.Make yarn weave, broken yarn rate on the Computerized flat knitting machine, large circle machine reduces greatly, improved production efficiency, for the deep level development of product is laid a good foundation.
4, the abrasion resistance of yarn: because degree of stretching, the depth of parallelism of fiber are relatively poor in the rotor spinning line, fiber radial displacement in yarn is very difficult.So revolving cup spin the abrasion resistance of single thread, strand higher by 20% ~ 25% respectively than RING SPINNING, 45% ~ 55%, promptly the fabric anti-fluffing anti-pilling ranking score you can well imagine high 0.5 ~ 1.0 grade, 1.0 ~ 1.5 grades.In the diversification fiber yarn is produced, can not increase under the prerequisite of yarn twist not increasing fibre length, not improving fibre fineness, effectively solve diversification phloem fiber yarn fabric anti-fluffing and anti-pilling problem.
5, the elasticity of yarn: the rotor spinning line receives the fiber alignment effect on structure during because of resultant yarn, and during resultant yarn than the influence of small tension receiving coil, the extension at break of yarn, work to break all are higher than ring spinning line.The good springiness of yarn can improve feel, taking and the plasticity of manufactured goods in everyday general purpose effectively.
6, the bulkiness of yarn: because straightening of fibers degree and arrangement degree are relatively poor in the rotor spinning line, sliver tension force is less in the yarn twisting process, and skin is entertained the winding fiber again, and yarn texture is fluffy.The bulking intensity of general rotor spinning line is higher by 12% ~ 18% than ring spinning line.The yarn bulkiness is good, can effectively improve the thick and heavy sense of the surface pattern and the lining of lining, makes the lining lines clear, and is thick and not heavy.
