Description
Technical field
The object of this invention is to provide a kind of two roller differential type secondary compartition exhibition yarn device, adopt spinning method and the application thereof of this device, the endless tow compartition belonging in ring spinning field launches protection composite spinning technical field.
Background technology
Along with the fast development of textile industry, the application of long filament is also more and more extensive, particularly aspect the utilizing of staple fibre.Noil in textile process process, short, the on the weak side fibrid of fuds fuddled isogonic increase; Reuse textiles gained fiber is compared with fibrillation with in intensity in length, also has certain gap; The shortcomings such as these are partially short, the fiber of class on the weak side can not spin or spun yarn strength is low, filoplume is many.So just cause this class fiber partially short, on the weak side not to be fully utilized.But the composite yarn of the coated short fiber of long filament can make up the deficiency of this respect, improve the utilization rate of staple fibre.
Short fiber/long filament composite yarn process units is all to carry out part transformation on traditional ring spinning yarn mechanism basis at present.As the utility model patent of Wang Wenge and Li Baocang (number of patent application: CN200320121270.5), on spinning support, step collector is set, sliver enters front leather roller by apron embedding mouth through step collector passage, long filament converges at front leather roller and sliver through collector front end, makes sliver and long filament form stable twist triangle zone.
Equipment (the patent No.: 200710061243) comprise three roller drafting mechanisms or four roller drafting mechanisms of a kind of coated yarn spinning of Tianjin University of Technology's invention, it is characterized in that: before drafter front roller, install a leading roller additional, an equipped leading rubber roll with circumferential grooves on leading roller, this leading roller forms leading jaw with leading rubber roll, and being arranged in the same level of drafter drawing-off jaw, and spacing and can regulate between leading jaw and drawing-off jaw; Between leading roller and front roller, a yarn positioner is also installed, this positioner is with two grooves that be arranged in parallel, be arranged on fixed bar, fixed bar is arranged on roller stand, positioner installation site should make the bottom surface of groove and drawing-off jaw and leading jaw in same level, and one of two grooves are corresponding on yarn outbound course with circumferential grooves, installation site is adjustable simultaneously.The people's such as Tang Yuyuan and Hopkinson, John Edmund achievement (the cotton type RING SPINNING of one-step method short fiber skin-core structure composite yarn), by the parts of repacking ring throstle, has adopted the special-shaped roller of surperficial fluting, has obtained having the Sirofil yarn of special construction and outward appearance.Sirofil yarn is the complex yarn forming at twist triangle zone composite twist, different both position distribution differences in knot structure that cause of staple fibre yarn bending rigidity relative to filament yarn and torsional rigidity, the latter is by fiber strip looping in centre, and yarn and filament surface have identical turn.It is a kind of Worsted technology based on RING SPINNING that Solospun spins, this technology is that a pair of special fluted roll is installed on traditional ring spinner, the fiber strip coming from front roller output can be divided and is split into some tuftlets whereby, thereby the twisting mill reason of spinning is changed, but special groove compartition is that staple fibre bundle is not filament yarn.
The technical scheme that above-mentioned patent proposes cannot effectively be protected partially short or ultrashort, on the weak side or fragile staple fibre mostly.

Adopt the step of the spinning method of said apparatus to be:
Get a long filament cylinder, by the endless tow on it 7 through individual pen twizzle 11 or under draw twizzle 12 location be centered in just the first center line 22 of compartition roller 2, and just compartition roller 2 of pile warp, because being greater than subdivision, its linear velocity splits the speed difference that the linear velocity of roller 3 forms, therefore, under the expansion effect of rotating at the first font groove 21, realization effectively, controllably just compartition exhibition yarn forms and flattens long filament 7a.Then, flattening long filament 7a is symmetrical in subdivision and splits the second center line 32 of roller 3 and feed, and pile warp subdivision is split roller 3, rotate under expansion effect at the second herringbone groove 31, carry out subdivision and split exhibition yarn, form filament filament layer, i.e. silk screen 7b, silk screen 7b is admitted between front upper roller 81 and front bottom roll 82, the front roller 8 that front upper roller 81 and front bottom roll 82 are ring throstle.
Divided and be split into after silk screen 7b when described endless tow 7, form silk screen 7b in twist triangle zone in lower floor, staple fibre yarn is at the two-layer fibre structure on upper strata, under gyroscopic action, silk screen 7b carries out composite spinning near holding staple fibre yarn under staple fibre yarn, thereby reaches continuously, the effect of covering, bright and clean and losing fibre preventing.
Following specific embodiment 1～3rd, to different fibers and line density thereof, select different long filaments, different rove bar and different compositely proportional and different composite yarning process parameters, be tension force, secondary compartition rod rotating speed, ingot speed, the front roller rotating speed of long filament, the spinning twist.Carry out by the spinning of of the present invention pair of rod differential type secondary compartition exhibition yarn device bright and clean composite spinning mechanism and method, and be spun into the bright and clean composite yarn of high.
Every thousand ingot end breakage rate hourly in record spinning when thousand ingots (individual /).Quality according to spinning with the quality of rove bar and long filament and final resultant yarn, calculates the row yielding of spinning.Adopt USTER instrument to measure the bar evenness (CV%) of resultant yarn.Adopt one-sided filoplume counting method to measure the filoplume of composite yarn, the hairiness index (F) of the bright and clean composite yarn of gained, refers in unit length yarn that extension elongation in single side face exceedes the filoplume accumulative total (root/m) F=A+Be of certain preseting length
-Cl, the setting extension elongation (mm) that l is filoplume, A, B, C are test constant.Adopt tensometer, measure the fracture strength (cN/tex) of resultant yarn; Elongation at break ε=(L-L
0)/L
0=Δ L/L
0wherein, L
0for former length, specimen length when L is tension failure, Δ L is absolute elongation value.Concrete implement and real data as follows with see the following form.
Embodiment 1: spinning reuse cotton/Tencel long filament composite yarn
