Abstract
The invention discloses the seamless felt of a kind of polishing, comprise base cloth layer, front fibrage, reverse side fibrage, base cloth layer front is implanted with front fibrage by the method for acupuncture, base cloth layer reverse side is implanted with reverse side fibrage by the method for acupuncture, it is characterized in that: the one side that described front fibrage deviates from base cloth layer is the flat surface after grinding process. The preparation method of the seamless felt of polishing is also provided. The seamless felt of polishing of the present invention, by sanding apparatus by rough felt surface rubbing, the method step of this woollen blanket finishing is simple, cost is low, and felt can be removed on the surface of hardening after deep fat roller heat treated, the seamless felt of polishing obtaining is difficult for forming felt mark on page surface in use, and the raising of page dewatering efficiency, has improved page quality.
Description
Technical field
The present invention relates to a kind of woollen blanket that is applied in paper machine press section and preparation method thereof, the concrete finger one finger seamless felt of polishing.
Background technology
Felt has an operation---needled flocking in production procedure, this operation is exactly that the fiber of carding is made to woollen blanket semi-finished product by the method acupuncture of acupuncture to base cloth, be used for the equipment of acupuncture in needled flocking machine, wherein pricker is to arrange according to certain rules, in acupuncture course, be with barbed pricker in the process of moving up and down, the fiber on woollen blanket top layer is brought into woollen blanket inside, the form of the similar rivet of fleece is wound around and composite for base fabric mutually. This process makes woollen blanket form rough surface, be commonly called as acupuncture trace, this irregular surface is easily reflected to the paper defects that forms felt mark on paper on the one hand, on the other hand due to this rough surface, while together entering nip from page, form different pressure on page surface, cause the dehydration inhomogeneities of page. The modification on felt surface at present all adopts the mode of hot trim, inswept from woollen blanket surface with heat radiation or live wire, make woollen blanket surfacing, but its surface smoothness of woollen blanket of this modified is inadequate, and can make woollen blanket surface harden, affect the efficiency of page dehydration.
Summary of the invention
For overcoming the deficiencies in the prior art, the invention provides the seamless felt of polishing that a kind of profile pattern is good, be difficult for forming on page surface felt mark.
The technical scheme that the present invention takes is: the seamless felt of a kind of polishing, comprise base cloth layer, front fibrage, reverse side fibrage, base cloth layer front is implanted with front fibrage by the method for acupuncture, base cloth layer reverse side is implanted with reverse side fibrage by the method for acupuncture, and the one side that described front fibrage deviates from base cloth layer is the flat surface after grinding process.
As the preferred technical scheme of the present invention, described base cloth layer comprises upper strata base cloth layer and lower floor's base cloth layer, and upper strata base cloth layer and lower floor's base cloth layer are directly stacked together, and front fibrage is implanted in base cloth layer surface, upper strata, and reverse side fibrage is implanted in lower floor's base cloth layer surface.
As the preferred technical scheme of the present invention, described upper strata base cloth layer is formed by warp and parallel braiding, and warp adopts polyamide fibre 4 strands, and parallel adopts Nylon 6 Monofilament.
As the preferred technical scheme of the present invention, described lower floor base cloth layer is formed by warp and parallel braiding, and warp adopts polyamide fibre 6 strands, and parallel adopts Nylon 6 Monofilament.
The present invention also provides the preparation method of the seamless felt of above-mentioned polishing, and its step comprises:
A, weave: weave base cloth layer grey cloth;
B, edge are repaiied: base cloth layer grey cloth two ends are set in together, make the base cloth layer grey cloth of end become endless loops base cloth layer grey cloth;
Chemical short fiber is laid in c, flocking: base cloth layer grey cloth is installed on flocking machine on base cloth layer grey cloth, obtains felt;
D, sizing: felt is carried out to thermal finalization arrangement;
E, surface finish processing: after having shaped, by felt tensioning, the one side that adopts sanding apparatus to deviate from base cloth layer to the front fibrage of felt is carried out grinding process, to improve woollen blanket surface smoothness.
As the preferred technical scheme of the present invention, described chemical short fiber is polyamide fibre 6 short fibers of fineness between 6D-40D.
As the preferred technical scheme of the present invention, the detailed step of step e surface finish processing is: the felt after sizing is stretched between the deep fat roller and idler roller of papermaking felt setting machine, the one side that front fibrage deviates from base cloth layer outwardly, starting forming machine drives felt to rotate with certain speed, sanding apparatus is that rotor surface is provided with blade, start moving the turning of rotor high-speed of sanding apparatus, the velocity ratio of rotor and felt is 80-100, adjust the distance between rotor and felt, epitrochanterian blade is contacted with the one side that the front fibrage of felt deviates from base cloth layer, cutting felt is to technological requirement.
The seamless felt of polishing of the present invention, by sanding apparatus by rough felt surface rubbing, the method step of this woollen blanket finishing is simple, cost is low, and felt can be removed on the surface of hardening after deep fat roller heat treated, the seamless felt of polishing obtaining is difficult for forming felt mark on page surface in use, and the raising of page dewatering efficiency, has improved page quality.
