334-335-336-338-312, the route of travel of the short leather lacing of downlink is 312-322-334-336-338-312.Uplink belt
Silk is spaced with downlink leather lacing, and the length leather lacing in uplink leather lacing or downlink leather lacing is also to be spaced.
Twisting part is twisting unit 411,412,413,414.
Nanofiber and common is prepared using the preparation method of a kind of nanofiber and the blended composite yarn of general fibre
During fiber blend composite yarn, first with the technological process of tradition spinning, traditional general fibre is pre-processed, then
Through grabbing cotton, opener, mixed cotton process, or by wool opening, wool blending step, general fibre shredding cleans, is uniformly mixed, then feeds
Entering general fibre web forming device, fiber by licker-in or breast cylinder shredding, by big Cylinder Carding networking and is transferred on doffer again,
Web is passed through from Static Spinning spinning appts and reception device, will be sprayed from Static Spinning spinning head by stripping hair roller or stripping of stripping-comb
The nanofiber interception gone out, formation nanofiber and general fibre composite fiber web are simultaneously compound into nanofiber and general fibre
Web slitting device.
Nanofiber and general fibre composite fiber web are by 311 holding of support hair roller, between feeding network access axis 312,313, skin
Band silk is clipped in the middle web, when web immediates vicinity (at the line of centres) close to the upper and lower bar axis 321,322 that cuts, into
Leather lacing on net axis 313 steps up a part for web with above cutting the protrusion of bar axis 321, and on network access axis 312
The protrusion that leather lacing cuts bar axis 322 with steps up another part of web, leather lacing and clamped web warp
When cutting bar axis and moving on, web is slit into fiber band under the action of shearing force, the width of fiber band and cuts the prominent of bar axis
It is essentially identical to play partial width.When above cutting bar axis 321 and going to jockey pulley 331 with fiber band, leather lacing takes away with fiber
Open and cut bar axis continuation uplink, long belt silk 341 reaches twister first row washboard after bypassing jockey pulley 332 with fiber band
At 411, and by between two row's of stranding with the hands plates of fiber band feeding, it is twisted into ribbon.And short leather lacing 342 bypasses jockey pulley with fiber band
Reached after 333 at twister second row washboard 412, be also sent between two row's of stranding with the hands plates, be twisted into ribbon.Under cut 322 band of bar axis
When fiber band and going to jockey pulley 334, leather lacing leaves with fiber band to be cut bar axis and continues traveling downwardly, 344 band of downlink long belt silk
Between fiber band around the 4th row's washboard 414 of twister is entered after jockey pulley 335, the short leather lacing 343 of downlink is with fiber
Band is around between arrival the 3rd row's washboard 413 of twister after jockey pulley 336.Fiber band is fed separately to each to rubbing with the hands by each leather lacing
After plate, by guide strip roller 337 and 338, it is returned to through the deep trouth for cutting bar axis on network access axis 313 and 312.
A kind of embodiment 2 of the blended composite yarn preparation facilities of nanofiber and general fibre：
The present embodiment difference from Example 1 is that the spinning appts of Nano- fiber preparation device employ single-column type
(single file formula) Multi needle spinning appts or matrix form (being not excluded for other shapes) Multi needle spinning appts, can also use abnormity rolling
The needleless Static Spinning spinning appts such as cylinder, spiral metal wire, straight wire, nanofiber, phase are prepared using above-mentioned spinning appts
Than single needle spinning appts, nanofiber yield can significantly improve, this belongs to general knowledge in the industry, repeats no more.
A kind of embodiment 3 of the blended composite yarn preparation facilities of nanofiber and general fibre：
The present embodiment difference from Example 1 is nanofiber and general fibre composite fiber web slitting device part
Using rigid cutting, the form rigidly cut is some rigid scissors arranged using fixing or being not fixed spacing, or is adopted
With a pair of of the roller pressed, one of surface of roller is cased with fixing or is not fixed several sleeves of spacing, another roller
Then surface configuration have it is fixed or be not fixed spacing can be along the tangent circular shear blade of sleeve described in foregoing roller, using being not fixed
The sleeve of spacing, blade are combined, and can produce the nanofiber and the blended complex yarn of general fibre of different fineness at the same time.
The invention is not restricted to embodiment discussed above, those skilled in the art can infer other variations according to the present invention
Form, these variant forms fall within subject of the present invention.
