The fiber 9 for successively winding the upper area B 22 during this on heart yarn 8, forms the first fibrous layer, then wind the fiber 9 in the area A 21, shape
At second layer fibrous layer.
It is illustrated in figure 5 the process flow chart of multilayer micro nanometer fiber covering yarn and its Yarn spinning method, comprising the following steps:
Step 1. is prepared, the blended fiber in the area A 21 and the area B 22, is sliced according to polybutylene terephthalate (PBT) and poly- to benzene two
After the ratio of formic acid glycol ester slice is mixed, mixed fiber 9 is sliced and carries out drying, at screw machine
Reason, then by melt extrusion, spinning pack is entered by metering pump and carries out melt-spraying spinning, is respectively formed two kinds of blended fibers.Again will
Heart yarn 8 is mounted on yarn core 11；
Step 2. starter, back yarn roller 12 rotate, heart yarn 8 are drawn from yarn core 11, extremely by the traction of lever jack 61
In first twisting rollers 41 and the second twisting rollers 42；
Step 3. is meltblown spinneret 2 and will be blended in micro nanometer fiber 9 landing to lace curtaining 31, and as shown in Figure 1 vertically falls in lace curtaining
On 31, there is aspiration channel 7 to form negative pressure guidance on 31 surface of lace curtaining below lace curtaining 31 and micro nanometer fiber is blended, the second twisting rollers 42 are inverse
Hour hands rotation, lace curtaining 31 start that blended fiber 9 is moved to first along the arrow direction loopy moving in Fig. 1 on lace curtaining 31
Wedge workspace between twisting rollers 41 and the second twisting rollers 42, since the first twisting rollers 41 and the second twisting rollers 42 are dust cage
Structure, dust cage structure are equipped with air intake device, and air intake device one end is connected to form negative pressure to micro-nano fibre by air hose and blower
Tie up 9 layers of formation suction-operated, by the reverse movement in the tangent of the first twisting rollers 41 and the second twisting rollers 42 to heart yarn 8 into
Row friction twisting, micro nanometer fiber layer cladding are wrapped in formation 9 covering yarn 8 of micro nanometer fiber on heart yarn 8；First twisting rollers 41 are leaned on
The diameter of nearly 5 one end of winding device is greater than twisting rollers close to the diameter of 1 one end of yarn feeding device, reduces the 8 ectonexine twist of covering yarn
Difference；Imperforate section, the side setting of length and lace curtaining 31 are equipped in the output end of the first twisting rollers 41, the second twisting rollers 42
There is non-porous 32 width of curtain to match, covering yarn 8 is crumpled using non-porous curtain 32 after the cladding twisting of lace curtaining 31 and twisted, yam surface
Filoplume can achieve effective control, improve the rounding finish of yam surface.
9 winding heart yarn of step 4. blended fiber forms winding structure yarn, by passing through in the traction to cylinder yarn 52 of lever jack 61
Wound-up roller 51 is wound into cylinder yarn 52.
Two different raw materials are used into different melt-blown spinneret dies, two kinds of micro nanometer fibers 9 is formed and is collected at lace curtaining
On 31, as the rotation micro nanometer fiber 9 of twisting rollers enters two twisting rollers friction twisting areas；Twisting rollers are dust cage structure, dirt
There is air intake device inside cage, micro nanometer fiber 9 is condensed upon dust cage surface under the action of air intake device, as dust cage rotation is micro-
Nanofiber 9 is transferred to carving in type groove between two dust cages, and two dust cages move toward one another, micro-nano by friction twist principle
9 layers of rotation cladding heart yarn 8 of fiber form 9 wrap yarn of multilayer micro nanometer fiber.
Heart yarn 8 passes through along dust cage axis direction from the type groove of carving between two dust cages, and the micro-nano at end is fed close to heart yarn 8
Rice fiber 9 forms the inner layer of covering yarn, and the surface layer of covering yarn is formed close to the micro nanometer fiber of output end.Since inner layer is micro-nano
Yarn diameter is small, twisting time is long when fiber starts twisting, when outer layer micro nanometer fiber starts big yarn diameter when twisting, twisting
Between it is short, cause the close outer layer of inner layer fluffy.A dust cage is small using input terminal diameter in the present invention, output end diameter is big sets
Meter, can effectively reduce the difference of ectonexine density.Moreover, close to output end, dust cage and one section of the use of lace curtaining 31 is non-porous sets
Meter, can be improved the surface smoothness of 9 covering yarn of micro nanometer fiber.
In the present embodiment, heart yarn 8 use conductive exothermal fiber filament, covered fiber 9 respectively using PBT/PET 70%/
30%, PET/PBT 30%/70% is raw material, using different spinneret dies, forms two kinds of component differences, fineness difference, thickness not
It is fine to form unique multi-layer helical looping structure micro-nano rice to micro nanometer fiber same, fluffy degree is different using friction twisting technology
Covering yarn is tieed up, this micro-nano multilayered structure of clad increases thermal resistance, is conducive to the heat for keeping heart yarn 8.Clad simultaneously
Micro nanometer fiber 9, it is soft comfortable, also there is antibacterial, airing function.Therefore, this multilayer micro nanometer fiber covering yarn
With the multiple functions such as heat preservation, antibacterial, ventilative, soft comfortable can be widely applied to a variety of woven, knitted textile fabric lifes
It produces, meets the exploitation demand of fabric product.The present invention uses the basic principle of FRICTION SPINNING twisting, with melt-spraying spinning technology knot
It is combined, the micro nanometer fiber that melt-spraying spinning is formed is evenly coated at core filaments surface, it is micro- to form a kind of new multiple layered structures
Nanofiber covering yarn.
It is the preferred embodiment of the present invention above, does not depart from original of the invention for those of ordinary skill in the art
Under the premise of reason, several variations and modifications can also be made, these also should be regarded as protection scope of the present invention.
