Abstract
The present invention proposes that a kind of efficient fast guiding can antibacterial hot-wind nonwoven cloth, fiber composite is by upper emulsion layer, mixed fiber layer and lower emulsion layer are combined with each other to be formed, and lower fibrage is combined with each other by the sparse fibrous layer in internal consolidated fibers and in outside and is formed, mixed fiber layer is mixed by bamboo charcoal fiber and thermoplastic synthetic fiber's uniform stirring, lower fibrage after molding is because of sparse fibrous layer with stronger permeability and consolidated fibers have stronger capillary phenomenon, sparse fibrous layer can carry out fast guiding to liquid such as moisture, the liquid such as moisture can be absorbed and be held rapidly by consolidated fibers, consolidated fibers and the mutual cooperation of sparse fibrous layer achieve the purpose that efficient fast guiding imbibition；And mixed fiber layer has the antibacterial of bamboo charcoal fiber, antibacterial environment protection and high imbibition moisture absorption.The present invention also propose a kind of efficient fast guiding can antibacterial hot-wind nonwoven cloth production method.
Description
Technical field
The present invention relates to tencel and technical field of composite preparation, and in particular to a kind of efficient fast guiding can press down

The following table face contact of horizontal piston plate and the first malthoid paper layer；Then using described in third device of rotation driving driving
Second end cover is rotated towards corresponding clockwise, corresponds each fourth hole and each third through-hole；Then it utilizes
4th lifting drive drives up the lower horizontal piston plate, squeezes in the second bonding powder bucket
Second homogeneous mixture of adhesive powder and air enters second internal cavity through each fourth hole and third through-hole,
In second internal cavity uniformly spread after uniformly sprayed upwards by each second spray orifice again, herein the second homogeneous mixture from
While second spray orifice is ejected into the cylinder main body, described second is utilized according to the volume that the second homogeneous mixture sprays
Lifting drive drives the synchronous decline of the second horizontal piston plate, the volume for spraying the second homogeneous mixture and described the
Two horizontal piston plates are corresponding to the second space volume between the first malthoid paper layer；When the amount for spraying the second homogeneous mixture
It when reaching demand, drives the second end cover to rotate towards corresponding clockwise using the third device of rotation driving, makes each
The fourth hole is staggered with each third through-hole, by the cylinder bottom seal of the second bonding powder bucket；
Then intracorporal first homogeneous mixture of the cylinder master and the second homogeneous mixture are heated using the heating layer,
The temperature of the first homogeneous mixture and the second homogeneous mixture is set to rise to 10-15 DEG C of fusing point lower than the adhesive powder；Then
It drives the first level piston plate to be moved down using first lifting drive, while utilizing described second liter
Drop driving device drives the second horizontal piston plate to be moved down, and the first level piston plate is made to be pressed down against first
Homogeneous mixture, while the second horizontal piston plate plays the role of aspirating downwards, makes the air in the first homogeneous mixture
It carries adhesive powder secretly and successively penetrates the second malthoid paper layer, upper fibrage, upper emulsion layer, mixed fiber layer, lower emulsion layer, cause
Close fibrous layer, sparse fibrous layer and the first malthoid paper layer and progressing into second space is mixed with the second homogeneous mixture,
The adhesive powder in the first homogeneous mixture can be bonded in the upper fibrage, upper emulsion layer, mixed fiber layer, lower latex at this time
Inside layer, consolidated fibers and sparse fibrous layer；Lower surface and the second malthoid paper layer when the first level piston plate
Upper surface contact after, drive the second horizontal piston plate to be moved up using second lifting drive, together
First lifting drive described in Shi Liyong drives the first level piston plate to be moved up, and keeps second level living
Upward second homogeneous mixture of seben, while the first level piston plate plays the role of being drawn up makes second
In even mixture air entrainment adhesive powder successively penetrate the first malthoid paper layer, sparse fibrous layer, consolidated fibers, under
Emulsion layer, mixed fiber layer, upper emulsion layer, upper fibrage and the second malthoid paper layer are simultaneously progressed into the first space and first
Homogeneous mixture mixing, the adhesive powder in the second homogeneous mixture can be bonded in the upper fibrage, upper emulsion layer, mix at this time
Inside condensating fiber layer, lower emulsion layer, consolidated fibers and sparse fibrous layer；Upper surface and institute when the second horizontal piston plate
After the following table face contact for stating the first malthoid paper layer, re-uses first lifting drive and drive the first level piston
Plate is moved down, while driving the second horizontal piston plate to carry out to moving down using second lifting drive
Dynamic, with this, up and down reciprocatingly the synchronous driving first level piston plate and the second horizontal piston plate are repeated as many times, to the upper cream
The lower open-work on the upper open-work and lower emulsion layer on glue-line is got through, and first homogeneous mixture and second is
All adhesive powders in even mixture can even adhesion cumulative distribution the upper fibrage, upper emulsion layer, mixed fiber layer,
Inside lower emulsion layer, consolidated fibers and sparse fibrous layer；Then using the heating layer it is intracorporal to the cylinder master it is described on
Fibrous layer, upper emulsion layer, mixed fiber layer, lower emulsion layer, consolidated fibers and sparse fibrous layer and in the first space and
Air in second space is heated, and the upper fibrage, upper emulsion layer, mixed fiber layer, lower emulsion layer, feltwork are made
The temperature of layer and sparse fibrous layer and the air in the first space and second space rises to the fusing point of the adhesive powder
More than, but lower than the upper emulsion layer, lower emulsion layer, upper fibrage, mixed fiber layer, consolidated fibers and sparse fibrous layer
Minimum fusing point melts adhesive powder completely and by the upper fibrage, upper emulsion layer, mixed fiber layer, lower emulsion layer, densification
Fibrous layer and sparse fibrous layer are bonded together；
Then the loading plate is driven to skid off from the cylinder main body using the sliding driving device, it will be described in bonding completion
Upper fibrage, upper emulsion layer, mixed fiber layer, lower emulsion layer, consolidated fibers and sparse fibrous layer take out.
2. a kind of efficient fast guiding according to claim 1 can antibacterial hot-wind nonwoven cloth production method, feature exists
In: utilize upper emulsion layer and lower emulsion layer described in template construct；The upper surface of the template is equipped with multiple equally distributed studs,
The height of the stud is greater than 1.5mm, and the diameter of the stud is 0.5-1.5mm, and the spacing between the adjacent stud is 1-
3mm；
Latex liquid is laid in template, the emulsion layer of solidification is removed after cooling solidification and is made with described in upper open-work
Upper emulsion layer and lower emulsion layer with lower open-work.
