Based on above-mentioned process units of the present invention, shown in composition graphs 1, the production technology of a kind of corduroy of the present invention, its technological process is as follows: Fig. 1 direction of arrow pressed by suede grey cloth, enter cut pile device 2, filling 2 by cut pile makes the floating latitude on suede grey cloth 1 all cut off, then suede grey cloth 1 is sent into brush-dewing machine structure 3, suede grey cloth 1 is first by atmospheric plasma pretreatment unit 3-3, make the surperficial plasma membrane disruption of suede grey cloth 1, quick dewing after being conducive to, rapid raising suede grey cloth 1 is containing damp rate, suede grey cloth 1 is by after atmospheric plasma pretreatment unit 3-3, the quick dewing of steam is carried out by steam showers component 3-4, make fine hair loose by brushing device 3-2 again, next the suede grey cloth 1 processed is singed by gassing frame 4, enter after singing to move back and boil the pre-treatment that rinsing combination machine 5 carries out suede grey cloth 1, then dyeed by dyeing machine 6, cloth after dyeing is sent into cut velvet device 7 and carries out napping, and carry out high-temperature shaping process by Final finishing setting machine 8, cut velvet is not easily lodged, then the novel not finished product of falling corduroy is obtained.
Concrete technology step and parameter as follows:
Corduroy fabric------to wet brushing,---singing,---------shape afterwards to boil drift in destarch in cut pile by dyeing---cut velvet---.
1, cut pile:
First corduroy fabric 1 is carried out broadwise tentering, then by cut pile device 2, guide pin 2-4 inserts in the radial suede lane of suede grey cloth 1, and under pushing needle bar 2-6 advances, cut pile circular knife 2-1 is slit into fine hair the floating weft yarn on suede grey cloth 1; Cut pile technological parameter is as follows: cut pile speed of a motor vehicle 4.5m/min ~ 6.5 m/min, hobboing cutter rotating speed 700r/min ~ 1000r/min.
Described broadwise tentering tentering is to weaving upper machine fabric width.
In cut pile operation, described guide pin needle point is ball-type, and ball-type diameter is at 0.2-0.3mm, guide pin needle point is toward in the 40-60mm length of backshank direction, guide pin fineness, from needle point 0.2-0.3mm, is transitioned into 0.5-0.6mm gradually, and guide pin needle point ball shape structure is designed with to be beneficial to and reduces the generation of grey cloth holing; Guide pin fineness differs, comparatively thick by being more carefully transitioned into from needle point toward backshank direction, and this partial design is conducive to the radial suede of guide pin fabric and does, and reduces bouncing pilotage phenomenon and occurs.
Described pushing needle bar is connected by arm axle with guide pin, in the process of pushing pin, with the propelling of pushing needle bar, angle is increased to 25 ° ~ 30 ° from 5 ° to the contact angle 2-7 of guide pin 2-4 and suede grey cloth 1 gradually, and this is designed with and is beneficial in the process of guide pin fabric radial suede lane, reduces leakage and cuts holing problem.
2, to wet brushing:
Grey cloth after cut pile passes through atmospheric plasma pretreatment unit with 15m/min ~ 40 m/min speed, carry out plasma discharge process, plasma discharge power is 100w ~ 50kw, the discharge process time is 10S ~ 60S, grey cloth by after plasma discharge process, then carries out jet humidification and bristle process successively.
Suede grey cloth generally adopts the direct dewing of spray vapour case containing damp rate, but because there is serous coat on suede grey cloth surface, after process, suede grey cloth is obviously inadequate containing damp rate, for addressing this problem, containing for making grey cloth that damp rate is large and matte is impaired little, adopting dress atmospheric plasma pretreatment unit before spray vapour humidification.Grey cloth after cut pile is passed through atmospheric plasma pre-processing device with 15m/min ~ 40 m/min speed, and carry out plasma discharge process, plasma discharge power is 100w ~ 50kw, and the discharge process time is 10S ~ 60S.Grey cloth is by after plasma preliminary treatment, and enter spray vapour case and the brush board mechanism in rear road, this part is identical with common process, does not repeat herein.
Singing 3, before cut velvet, destarch, boil drift, dyeing is identical with common process, do not repeat herein.
4, cut velvet:
After corduroy fabric is dyed, enter cut velvet operation, conventional corduroy processing does not have this procedure, and for realizing the non-lodging of corduroy fine hair, cut velvet operation of the present invention adopts positive and negative bristle technique, to ensure that fine hair uprightly enters Final finishing process.
Shown in composition graphs 5, corduroy fabric after dyed is successively through bristle roller, bristle roller adopts 6 ~ 8 groups of fur bristle rollers, and the rotation direction of 4 ~ 6 groups of fur bristle rollers is inverse cloth transmission direction, and the rotation direction of 1 ~ 3 group of fur bristle roller is along cloth transmission direction.This design ensure that bristle is abundant, ensures that the fine hair on matte has all been brushed.
Corduroy fabric bristle fully after, at the brush through last group forward bristle roller 7-2, by sizing groove 7-3 at corduroy fabric uniform application composite assistant, to increase elasticity, make fine hair through after road shape after there is good fine hair effect resistant to lodging.
The formula of described composite assistant, comprises following composition by weight percentage:
Environmental protection stiffening agent: 40% ~ 60%;
Formaldehyde-free crease-proofing finishing agent: 40% ~ 60%
Surplus is deionized water.
Described environmental protection stiffening agent is preferably environmental protection stiffening agent LD-4865, and described formaldehyde-free crease-proofing finishing agent is preferably formaldehyde-free crease-proofing finishing agent BTCA.
5, shape:
Corduroy fabric, after cut velvet operation, enters setting machine and carries out high-temperature shaping, the auxiliary agent on fine hair is cross-linked film forming to obtain lasting straight elevator effect and elasticity, and sizing also can have fine hair and eliminates stress, and keeps the effect of DIMENSIONAL STABILITY.For ensureing fabric dimensionally stable, setting temperature should not be too low, but temperature is too high, and corduroy change color can be relatively more serious, shaping time is 30s ~ 45s, setting temperature be 150 DEG C ~ 165 DEG C for best.
After sizing, the corduroy fabric of acquisition has excellent fine hair effect resistant to lodging.
According to production technology of the present invention and equipment, adjust different technological parameters, obtain following concrete preparation embodiment, under following examples are intended to that different technology conditions is described, the performance difference of the corduroy fabric of acquisition.
