Description
Technical field:
The present invention relates to field of new materials, are especially a kind of preparation method of flexible yarn of weaving.
Background technique:
The composite material of existing continuous fiber reinforced thermoplastic resin is mostly sheet material, raw because of the obstruction of dipping technique
Production speed is smaller, if fiber cannot be fully extended, dipping effect is extremely difficult to perfect condition.In addition, being usually fibre when dipping
It ties up bed to operate, if sheet material homogeneity is poor after dipping, it is difficult to the big volume of harvest.And continuous fiber reinforced thermoplastic sheet material is in mechanical property
Energy aspect has one-way, its application field is caused to be greatly affected.
Summary of the invention:
The technical problem to be solved by the invention is to provide it is a kind of ensure thermoplastic resin cladding after fiber it is flexible
Property, the preparation method of the flexible yarn of weaving that can wind and can weave.
The technical solution of the invention is as follows, provides a kind of preparation method of flexible yarn of weaving, including following technique stream
Journey, yarn releasing-dipping-cooling-winding, wherein fiber enters the fiber channel of impregnation mold, every fibre after yarn releasing equipment yarn releasing
Dimension individually enters in corresponding fiber channel, and the resin for corresponding and being connected to fiber channel is additionally provided in impregnation mold
Runner, by extruding machine by the resin of melting inject in each resin flow channel with the fiber contacts in corresponding fiber channel, to fibre
Dimension carries out pre-preg, and fiber surface is made to form resin layer under the premise of fibrous inside keeps shredded dried bean curd, then passes through cooling equipment
It is cooled down, fiber after cooling is wound by winding device.
Preferably, resin flow channel is arranged in a mutually vertical manner and is connected to fiber channel.
Preferably, the inlet and outlet of fiber channel is respectively equipped with the pore size control valve of fiber disengaging.
Preferably, resin flow channel is equipped with the control valve of control resin flow.
It is formed preferably, fiber passes through after cooling after pressure roller further cools down by shaper.
Preferably, the pressure of resin flow channel is 50kpa-120kpa, fiber speed 25-120m/min, fiber channel
Length be 300-1200mm.
Further, the resin of resin flow channel conveying is PP resin, and the pressure of resin flow channel is 60kpa, and fiber speed is
30m/min, the length of fiber channel are 350mm.
Using after above scheme compared with prior art, the invention has the following advantages that and continuous fiber reinforced thermoplastic
Unlike composite material one-way tape: not needing to be unfolded when fiber impregnation in 1. techniques；2. being monofilament before and after fiber impregnation
Beam；3. good flexibility is still presented after fiber impregnation, can wind and can be used for weaving；4. fiber is partial immersion, at it
Surface forms one layer of unformed resin layer, and fibrous inside is still shredded dried bean curd.5. speed of production may be up to 100m/min, more continuous than existing
It is several times to tens times fast that fiber reinforced thermolplastic presoaks equipment.
Detailed description of the invention:
Fig. 1 is schematic diagram of the invention.
Specific embodiment:
With regard to specific embodiment, the invention will be further described with reference to the accompanying drawing:
As shown in Figure 1, a kind of preparation method of weaving with flexible yarn, including following process flow, yarn releasing-dipping-cooling-
Winding, wherein fiber enters the fiber channel of impregnation mold 2 after 1 yarn releasing of yarn releasing equipment, and every fiber individually enters pair
It is additionally provided with the resin flow channel for corresponding and being connected to fiber channel in the fiber channel answered, in impregnation mold, passes through extruding machine
The resin of melting is injected in each resin flow channel with the fiber contacts in corresponding fiber channel, pre-preg is carried out to fiber,
Fibrous inside keeps making fiber surface form resin layer under the premise of shredded dried bean curd, is then cooled down by cooling equipment 3, after cooling
Fiber wound by winding device 4.Preferably, fiber passes through shaper 6 after passing through the further cooling of pressure roller 5 after cooling
Model shape according to needed for dipping fiber of sizing, shaper is set.Unwinding equipment, winding device, cooling equipment are
The conventional equipment of this field, does not specifically describe.The resin flow channel of impregnation mold is arranged in a mutually vertical manner and is connected to fiber channel,
The inlet and outlet of fiber channel is respectively equipped with the pore size control valve of fiber disengaging, and resin flow channel is equipped with control resin flow
Control valve.
It holds above-mentioned, further illustrates, to realize that fibrous inside is still that fiber surface is made under the premise of shredded dried bean curd to form indefinite form
The pressure of resin layer, resin flow channel can be set as 50kpa-120kpa, fiber speed 25-120m/ according to different fiber properties
Min, the length of fiber channel are 300-1200m.Wherein, for impregnating 1200tex glass fiber yarn, resin flow channel conveying
Resin is PP resin, and the pressure of resin flow channel is 60kpa, and fiber speed 30m/min, the length of fiber channel is 350mm.It is logical
The cooperation of resin flow channel pressure, fiber speed and fiber channel length is crossed, to realize above-mentioned technique requirement.The technique may insure
The flexibility of fiber after thermoplastic resin cladding can wind and can weave, and the fiber cloth after weaving has soft well
Toughness, very strong designability, and the fiber content of prepegged strands can be adjusted by changing mold pressure inside the resin, to set
It counts the mechanical performances such as intensity, the rigidity of product and can be used for forming complicated shaped piece, extend use scope and application field.
The present invention is unlike continuous fiber reinforced thermoplastic composite material one-way tape: in 1. techniques when fiber impregnation
It does not need to be unfolded；2. being filament tow before and after fiber impregnation；3. good flexibility is still presented after fiber impregnation, can wind and can
For weaving；4. fiber is partial immersion, it is formed on its surface one layer of unformed resin layer, fibrous inside is still shredded dried bean curd.5.
Speed of production may be up to 100m/min, several times to tens times faster than existing continuous fiber reinforced thermoplastic preimpregnation equipment.
Only the preferred embodiment of the present invention has been described above, but is not to be construed as limiting the scope of the invention.It is all
The equivalent structure or equivalent flow shift done using description of the invention, be included in scope of patent protection of the invention it
It is interior.
