Description
Technical field
The invention belongs to fiber preparation fields, and in particular to a kind of preparation method of the pure spinning mixed yarn of akund.
Background technique
Akund is grown out from the seed of Calotropis gigantea, is mainly made of cellulose, is belonged to natural plants
Fiber.Akund is similar with bombax cotton, and alternative bombax cotton is used for textile manufacturing, and the fabric being made into was both sericeous
Smooth texture, and have the gas permeability and comfort of similar cotton fabric, while the degree of hollowness of the cross section of akund is larger, energy
It is enough to be used as potential water suction oil absorption material, heat insulating material and buoyant material etc., it has broad application prospects.
Opening picking, cotton carding, drafting, rove and spun yarn are had to pass through in the spinning process of akund in the prior art
Etc. processes, the method that can be wherein used in spinning process have RING SPINNING, SEILE textile, compact spinning or close SEILE textile, RING SPINNING
Schematic diagram is as shown in Figure 1, RING SPINNING is to feed drafting system after rove unwinds out from flyer bobbin, and the yarn after drawing-off is by preceding sieve
It is passed through on the wire loop covered on rings, is wound up on the spool being tightly placed on spindle, then ingot by twizzle after drawing output
Sub- revolution at a high speed drives wire loop revolution at a high speed on rings by the sliver of some tension, and the every single-revolution of wire loop, which is just given, to be led
Yarn after stretching adds a turn, since the speed of wire loop lags behind the rotational speed of spool, thus keeps front roller continuous
The sliver of output is wound up on spool；SEILE textile schematic diagram is as shown in Fig. 2, SEILE textile is by two root thickness yarns according to a certain distance
It is continuously fed into the draft area of ring spinner in parallel, two single thread yarns, this two single thread palpuses are exported by front roller after drawing-off
Item converges again after tentatively being twisted respectively and forms yarn through further twisting, since SEILE textile is that two root thickness yarns are led simultaneously
Convergence twisting is an one thread after stretching, according to and rationally discuss, Yarn Evenness that SEILE textile technique is spun into improves, and thick, details can be obviously
It reduces；Compact spinning schematic diagram is as shown in figure 3, compact spinning is to increase a fiber aggregate before ring throstle front roller nip
Device, the device is by the contraction and polymerization to yarn, so that spinning twist triangle zone substantially eliminates, fiber strip is by preceding
After roller nip output, mesh apron is first passed through, on a special-shaped aspiration channel, special-shaped air draught pipe surface is provided with the apron housing
Double flute, when yarn passes through mesh apron, due to airflow function in anisotropic aspiration channel, yarn is shunk, and is polymerize, rotation, gradually from flat
Flat-shaped convergence is cylindrical body, and the head end of fiber is twisted into yarn in yarn body, therefore gained yam surface is bright and clean, and filoplume amount is bright
Aobvious to reduce, yarn texture is even closer；Close SEILE textile schematic diagram is as shown in figure 4, close SEILE textile is that one kind is tightly combined spinning
With the spinning method of SEILE textile technology, on ring spinner, two root thickness yarns are flat through double horn mouth according to a certain distance
Row is continuously fed into draft area, after fiber strip comes out from front roller nip, first passes through mesh apron, the apron housing is different at one
On shape aspiration channel, special-shaped air draught pipe surface is provided with double flute, and the two root items come out from front roller nip are born by special-shaped aspiration channel
The effect of pressure gas stream is adsorbed on the position that mesh apron surface corresponds to double flute, while yarn shrinks under the action of air-flow and gathers,
Yarn after gathering becomes the close Siro Yarn of any surface finish of similar ply yarn structure after twisting.
And in carding process frequently with cotton carding device structural schematic diagram as shown in figure 5, in carding process, fiber needs
Successively to pass through licker-in, combing plate, cylinder, cover board and the multiple strike of doffer, especially work of the fiber in cylinder and cover board
Qu Zhonghui repeatedly combs strike by the needle tooth of cylinder and cover board, since the fiber strength of akund is low, degree of hollowness 80
~90%, cell wall is carefully thin, has rigidity, therefore, in the process, akund majority can be by the combing effect between needle tooth
It damages and is broken or is directly formed powder, therefore akund generally can not use traditional cotton carding device, that is, cover-plate type to comb
Machine carries out being combed into item.In addition, akund is generally more crisp, electron scanning longitdinal cross-section diagram and view in transverse section such as Fig. 6
Shown in 7, as can be seen from the figure akund is longitudinal without song is turned, and surface is excessively smooth, therefore reverses between akund
Obvolvent effect is small, is not easy to be controlled in draft area simultaneously because its cohesive force is poor, fiber stream can not be condensed on doffer surface
As soon as layer web can not also be collapsed into item through horn mouth, the carded sliver is formed.
Therefore, study a kind of can realize that the smooth of akund at item and spins in the case where lower damage
Method have a very important significance.
