Main component can be divided into: terylene, polyamide fibre, acrylic fibers, polyvinyl, polypropylene fibre, spandex, polyvinyl chloride fibre, aramid fiber, viscose rayon etc..By its length scale
Lattice can be divided into: long filament and staple fiber.In staple fiber, it can be divided into again by distribution of lengths feature: wait long fibres and different long fibre.
Equal long fibres be usually with dedicated cutting machine made of, the length of fiber be it is equal, have cotton staple in
Point of long fibre.Cotton-type short fiber has 33mm, 35mm, 38mm, 41mm plurality of specifications；Medium staple chemical fiber have 45mm, 51mm, 60mm,
65mm plurality of specifications.And different long fibre is made from crush cutting method, since the product of different long fibre processing more has the wind of wool fabric
Lattice, so it is the different length made from crush cutting method that the short fibre of wool type is mostly, distribution is generally 76~150mm, is generally directly prepared into
Staple fiber continuous strip.
It is built upon under such theoretical and premise currently, why cotton chemical fibre is equal long fibres, first is that, by
Shorter in cotton chemical fibre, the Length Regularity for improving fiber is conducive to improve yarn strength；Second is that common chemical fibre, is such as washed
Synthetic fibre and polyamide fibre etc. have enough strengths, can withstand the violent carding role of carding machine；Third is that long fibres is waited to will not influence comb
Cotton machine carding role and mixed effect；Fourth is that for multiple fiber it is blended for, it is excellent in the effect that carding step is mixed
In the mixed effect in mixing in doubling step；Fifth is that crush cutting method can be made at present due to being limited and above-mentioned reason by the prior art
Standby different long fibre only has wool type.

(3), circle item processing:
The tow that four times are stretched after the completion of crush cutting processing in bar cylinder, obtains can be used for drafting through coiling device circle
The staple fiber strip of processing；
The technical equipment scheme that fiber continuous fiber item is produced in crush cutting is: forming multiple lead by several draw rolls on stretch breaking machine
Area is drawn, the every stretching action that it is subject to by a drawing area of tow is just further violent, when the degree that tow is stretched is more than
Fibrous fracture elongation limit when, will be produced fracture at any weakness of monofilament, due to its tension failure point be it is random,
It is not on the same section, although fiber has been staple fiber state, whole one thread will not be broken, through such crush cutting system
The finished endless tow of item through coiling device circle in bar cylinder, just at can be used for drafting processing staple fiber strip.
Two, drafting is blended prepares fabric
To enclose the obtained staple fiber strip of item together with cotton fiber with and feed the blended machine of drafting and carry out blended, centainly mixed
The blended item of spinning ratio chitin fiber, and then rove is obtained, spun yarn is made in rove, spun yarn is fed into weaving equipment or knitting
Corresponding fabric can be obtained in equipment.
The tension balancer, be by it is several to the tension roll assembly configured up and down at, the quantity of jockey pulley can be
3,5,7,9,11, or more.Jockey pulley can passively turn round under the drive of endless tow.Jockey pulley has balanced each root long tow
And in endless tow each root long thread tension effect, to improve the Length Regularity of draft cutting fibre.
Described expands device, be expanded by one or more roller group at, the surface for expanding roller has from expanding roll shaft
The raised line around spiral revolution extended to centre to both sides, by the active reversed turning for expanding roller, in the work of helical form raised line
Under, each root long silk in endless tow can be made gradually to expand in certain width, thus the overlapping between reducing long filament, so as to
Crush cutting roller can sufficiently clamp each root long silk in crush cutting, to improve crush cutting efficiency.
The stretch-breaking device, by multiple drawing district's groups at tow fills after the extraction of tow case by tow tension equilibrium
Set and expand device into the first drawing zone with tow, the first drawing zone is made of two groups of pulling rollers, in the drawing zone, tow by
Tension force stretching, since drawing multiple is smaller (1.02-2.85), only extremely least a portion of long filament is pulled off, and main function is to make silk
Beam stretched straight parallel as far as possible arranges.Then, tow enter the second drawing zone, the second drawing zone equally by two groups of drawing mind roller groups at,
In the drawing zone, since drawing multiple is larger (1.15-5.85), almost all of fiber is because by powerful drawing-off pulling force
And be gradually broken, but there is also the fibers that do not break.Hereafter, tow enters third drawing zone, and third drawing zone can be also
Be made of two groups of pulling rollers, pull multiple between 1.10-5.85, the fiber that the second drawing zone is pulled off not yet will be at end
Drawing area is pulled off, this drawing area is primarily used to the longest fiber length in control crush cutting item.If a other in tow
Fiber is pulled off not yet in third drawing area, can be further added by one the 4th drawing area, and so on.Finally, after crush cutting
Strip makes fiber generate machine crimp, enters in bar cylinder through coiling device under the pressure pressurization of front leather roller and preceding bottom roll.
One group of crush cutting roller, can be by two or three or four crush cutting roller groups at.It answers on the surface of crush cutting roller
Smooth, adjacent crush cutting roller should be able to be in close contact, and strong gripping be formed to tow, and linear speed having the same at contact point
Degree.Stretching to be subject to tow is stepped up, and each gauge pulled between area should be gradually reduced, and usual third pulls area, and
(or) gauge in the 4th drawing area is slightly larger than or equal to the quasi- nominal length for leading protruding end, if short-staple is usually 38mm.
Gauge between each drawing area refers in drawing area between two groups of pulling rollers, in the middle part of pulling roller
Gauge.Because in the present invention, crucial innovative point is: the gauge in each drawing area, it is big in one, another along the axial direction of crush cutting roller
Trapezoidal shape under one, the difference of large and small head gauge are 0.01 between 30mm.Such design can force in crush cutting area
The fracture sequence of endless tow, gradually to big gauge side random fracture in an orderly manner, can effectively reduce drawing from close setting side
Power, so that the diameter reduction for crush cutting roller creates condition, as the diameter of crush cutting roller can be by existing wool type fiber crush cutting item
The 50mm or more of equipment is decreased to 30mm, makes to pull the gauge in area close to the length of cotton fiber, as 38mm is possibly realized.Described
Coiling device can be such that the orderly geosphere of ribbon made from crush cutting is wound in bar cylinder using upper common coiling device of weaving.Institute
The falling fiber device stated can use air-flow falling fiber device, or mechanical falling fiber device, make to be led disconnected fiber and leave in time finally
One group of crush cutting roller.
(1) compared with chemical fibre common at present directly prepares stretch-breaking technology and the equipment of wool type fiber, crush cutting of the invention
System technology and equipment can prepare shorter fiber, such as short-staple.Because it is all hair that chemical fibre common at present, which is directly prepared,
Fiber type, i.e. fibre length are all between 76-120mm.This is because each group of existing crush cutting system technology and equipment is led
Cut the gauge between roller be it is parallel, i.e. the suffered stretching of the endless tow between two adjacent groups crush cutting roller be it is completely same,
The fracture of long filament disorderly random fracture completely, so as to cause the increasing of crush cutting pulling force.In order to ensure that crush cutting roller has enough crush cuttings
Pulling force, it is necessary to increase the torque of crush cutting roller, to force the diameter for increasing crush cutting roller.Due to keeping the length of draft cutting fibre larger,
There is no problem for the diameter of increase crush cutting roller.But when preparing close to the staple fiber of the length of cotton fiber, existing technology and
Equipment there is problem, because of the length of short-staple chemical fibre usually only 38mm.In order to solve this problem, the present invention couple
Gauge between two groups of crush cutting rollers has carried out original creation and has sexually revised, and the gauge in each crush cutting area is made to have original parallel separation to change
For step ga(u)ge, to effectively reduce crush cutting power, also make it possible the diameter for reducing crush cutting roller.
(2) blank of existing crush cutting item has been filled up in the utilization that tension balancer and tow expand device, is crush cutting roller
Tow and orderly stretch broken fiber are effectively held, reduces crush cutting pulling force and creates condition.
(3) it with existing short-staple square-cut technology compared with equipment, is cut off using technology and equipment of the invention
Fiber, due to adequately being stretched, tension failure strength can be improved 10% or more, and for low strong fiber, such as shell is poly-
Sugared fiber and alginate fibre etc. are estimable.
(4) with existing short-staple square-cut technology compared with equipment, in the technique of the present invention, since fiber exists
By multi-drawing before breaking, the long filament of viscous connection originally is set to borrow traction action and separate, therefore there is preferably dispersion
Degree.(5) it is different long fibre using fiber prepared by technology and equipment of the invention, and has preferable dispersion degree, therefore spinning
In the process, will not be isometric and viscous because of fiber, and the synchronous drawing-off of generation in drafting, rove and spun yarn manufacturing procedure, make resultant yarn
With the better fineness uniformity.
