Abstract
The present invention relates to a kind of method for reducing strength loss in cotton fiber felt acupuncture course, belong to technical field of textile processing.When described method refers to use in cotton fiber felt needling process to the cotton fiber net after shredding combing and lapping by acupuncture platform upper surface, negative-pressure adsorption is carried out to the cotton fiber net of puffy under condition of negative pressure, cotton fiber net is adsorbed to shrink to negative pressure traffic direction, while cotton fiber net is shunk, the upper acupuncture board pricker above acupuncture platform carries out acupuncture to the cotton fiber net after contraction.Negative pressure first to the cotton fiber net of puffy adsorb contraction, and to realize cotton fiber net closely knit, reduce acupuncture number, reduce damage of the pricker to fiber, strength loss is reduced, so as to improve the acupuncture effect of cotton fiber felt and final product quality, the cost of production is reduced.
Description
Technical field
The present invention relates to a kind of method for reducing strength loss in cotton fiber felt acupuncture course, belongs to textile process technology neck
Domain.
Background technology
Cotton fiber felt is because its product is soft, fluffy, good permeability.It is widely used in clothes, dress ornament, cushion, household to use
The packing material of product, the decoration of indoor wall, it is also possible to make the material of shoe-pad.The manufacturing process of normal conon fibrofelt is that cotton is fine
Dimension carries out lapping after shredding combs, if carrying out acupuncture through dried layer cotton fiber net with the pricker pierced with hook, when pricker pierces
Enter the cotton fiber beam formed during cotton fiber net and pass through cotton fiber net, fibre bundle runs through between different layers cotton fiber net, on the one hand
Add the interlayer strength between cotton fiber net；On the other hand cotton fiber in every layer of web is also made from soft fluffy state to closely knit
State changes, and gradually forms the cotton fiber felt with interlayer strength, and the effect of acupuncture includes densification and reinforcement effect, and it has
The process of body is when pricker is pierced into cotton fiber net, and pricker band kinetodesma moves, and is passed through by the cotton fiber that pricker band is lived with pricker
Cotton fiber stratum reticulare, cotton fiber mutually tangles in motion process, obvolvent forms fibre bundle, cotton fiber net is produced certain squeeze
Pressure, is compressed cotton fiber net.Pricker be pierced into certain depth after go up, now crochet hook be forward, cotton fiber depart from hook thorn with
The state of near vertical, which is stayed in cotton fiber net, forms the process that acupuncture is realized in riveting effect, cotton fiber net is realized by riveting
The purpose of reinforcing.Such as Chinese patent publication No. CN107142614A, date of publication 2017 year 09 month 08 day, innovation and creation it is entitled
" a kind of preparation method of acupuncture cotton ", this application case, which discloses, to be included in the surface coating sizing material of acupuncture cotton and causes the table of acupuncture cotton
Face assigns layer protective layer.During it is disadvantageous in that by acupuncture formation cotton fiber felt, due to cotton fiber net acupuncture
During it is more fluffy between cotton fiber reach closely knit less efficient, the number of acupuncture, which increases, causes acupuncture to cotton fiber
Damage larger.
The content of the invention
For above-mentioned problem, it is an object of the invention to provide one kind to reduce strength in cotton fiber felt acupuncture course
The method of loss, to achieve these goals, its technical solution is：
A kind of method for reducing strength loss in cotton fiber felt acupuncture course, described cotton fiber felt negative pressure needle-punching method are
Finger sets negative pressure device below acupuncture platform, and the cotton fiber net after shredding combing and lapping is with 5-15m/min transporting velocity
During by acupuncture platform upper surface, the cotton fiber net of puffy is born under conditions of being 0.1-5MPa in the negative pressure of negative pressure device
Pressure absorption, the cotton fiber net after absorption is shunk to negative pressure traffic direction, while cotton fiber net is shunk, above acupuncture platform
Upper acupuncture board pricker carries out acupuncture with 1000-2000 times/min frequency to the cotton fiber net after contraction, and upper acupuncture board pricker is close
Spend for 1000-1500 pieces/m.
As a result of above technical scheme, the present invention be on the premise of existing cotton fiber felt needling process is not changed,
Acupuncture is carried out to the cotton fiber net after shredding combing and lapping under condition of negative pressure.Cotton of the negative pressure of negative pressure device to puffy
Web carries out negative-pressure adsorption, because the air-flow that the negative pressure of negative pressure device is formed makes cotton fiber in cotton fiber net fit perfectly in acupuncture platform
On, the space between cotton fiber reduces, and bottom cotton fiber net is shunk to negative pressure direction first, then the same bottom of the cotton fiber net on upper strata
Cotton fiber net is gradually shunk to negative pressure direction successively, and final cotton fiber net increases to negative pressure traffic direction overall shrinkage, bulk density
Greatly, cotton fiber net reaches dense state.While cotton fiber net is shunk, the upper acupuncture board pricker above acupuncture platform is to shrinking
Rear cotton fiber net carries out acupuncture, because cotton fiber net reaches dense state before acupuncture, the cotton fiber radical in unit volume
Increase, the increase of frictional force between cotton fiber, when pricker is to cotton fiber net acupuncture after contraction, pricker, which declines, drives cotton fiber
Cotton fiber amount in beam increases, and the frictional force increased between cotton fiber the increase of cotton fiber amount causes cotton fiber to tighten close and obvolvent
Power strengthens, so that the riveting effect of cotton fiber beam is strengthened, the interlayer strength between cotton fiber net increases.Therefore, this is employed
Technical scheme, negative pressure first to the cotton fiber net of puffy adsorb contraction, and to realize cotton fiber net closely knit, reduces acupuncture
Number, reduce damage of the pricker to cotton fiber, strength loss is reduced, and cotton is improved to the cotton fiber net progress acupuncture after closely knit
The acupuncture effect and final product quality of fibrofelt, and the feed increcement to cotton fiber felt is the method increase, add cotton fiber felt
Bulk density and product quality, reduce the cost of production.
Embodiment
The cotton fiber felt negative pressure needle-punching method of the present invention is described in further detail with reference to specific embodiment：It is a kind of
The method for reducing strength loss in cotton fiber felt acupuncture course, this method is in existing cotton fiber felt needling process is not changed
Cotton fiber shredding combing, cotton fiber lapping, cotton fiber net acupuncture process, using setting negative pressure device, negative pressure below acupuncture platform
Device can use vavuum pump or centrifugal fan, and the cotton fiber net after shredding combing and lapping process is with 5-15m/min conveying
When speed is by acupuncture platform upper surface, the cotton fiber net of puffy is entered under conditions of being 0.1-5MPa in the negative pressure of negative pressure device
Row negative-pressure adsorption, the cotton fiber net after absorption is shunk to negative pressure traffic direction, while cotton fiber net is shunk, on acupuncture platform
The upper acupuncture board pricker of side carries out acupuncture, upper acupuncture board thorn to the cotton fiber net after contraction with 1000-2000 times/min frequency
Pin density is 1000-1500 pieces/m.Negative pressure first carries out absorption contraction to the cotton fiber net of puffy, makes cotton fiber net connection tight
It is close, the darted section that densification is realized in existing cotton fiber felt needling process is instead of, reduces the number of acupuncture, reduces
Damage of the pricker to cotton fiber, strength loss is reduced, so as to improve the acupuncture effect of cotton fiber felt and final product quality, and the party
Method improves the feed increcement to cotton fiber felt, reduces the cost of production.
