Description
Technical Field
The invention belongs to the technical field of non-woven fabric production equipment, and particularly relates to a lapping method and a lapping device for preparing filament non-woven fabric by a wet spinning technology.
Background
The filament non-woven fabric is widely applied to the fields of medical treatment and health, agriculture, industry, automobiles and the like due to the excellent performance of the filament non-woven fabric. Compared with the short fiber non-woven fabric, the filament non-woven fabric can enable the non-woven fabric to be thinner and transparent, and the strength is better. At present, the preparation of filament non-woven fabrics mainly comprises a spunbond method and a wet spinning method. The non-woven filament fabric is prepared through extruding and drawing polymer to form continuous filament, laying the filament into web, and self-bonding, heat bonding, chemical bonding or mechanical reinforcing to obtain non-woven fabric. The main process steps of wet spinning are as follows: spinning solution-solidifying-washing-winding-bundling-stretching-curling-cutting-secondary washing-wet opening-drying-opening-packing. The specific process flow is as follows: preparing viscose: comprises the steps of dipping, squeezing, crushing, aging, yellowing, dissolving, curing, filtering, defoaming and the like. Spinning and forming: and (3) adopting wet spinning. Viscose forms thin flow through a spinneret orifice and enters an acid-containing coagulation bath, alkali in the viscose is neutralized, the thin flow is coagulated into filament, and cellulose xanthate is converted and regenerated into cellulose. Thirdly, post-processing: the formed fiber needs to be subjected to post-treatment processing such as water washing, neutralization, water washing, oiling, drying and the like.
CN 105401332 a discloses a process and an apparatus for preparing viscose filament non-woven fabric by wet spinning, comprising the following steps: a spinning process (1) and preparation of a spinning solution; (2) performing a stock solution solidification reaction, (3) forming viscose fibers; (4) washing with water; (5) and drying: a non-woven fabric forming process; (6) and laying a net: uniformly dispersing and laying the dried nascent viscose fiber tows on a net curtain of a net forming machine to form filament fiber nets which are mutually crossed and stacked; (7) carrying out spunlace reinforcement; (8) and drying; (9) and (6) rolling. The equipment consists of a wet spinning device and a non-woven fabric forming device. Relevant steps are omitted in the steps of the traditional wet spinning process, and the semi-finished viscose fiber filament is directly adopted for producing the non-woven fabric, so that the process breaks through the traditional concept of using the finished fiber filament for secondary non-woven fabric production, effectively saves the production cost, reduces the pollution to the environment in the process and improves the production efficiency. Meanwhile, CN 105420920A, CN 105316869 a also discloses a process and an apparatus for preparing pure alginate fiber and pure chitosan fiber filament non-woven fabric based on wet spinning technology, although filament non-woven fabric can be prepared by wet spinning, the thickness of filament non-woven fabric product obtained by spunlace can not reach uniformity due to uneven laying of filament fiber, that is, by using wet spinning technology, filament fiber obtained is directly laid and stacked to prepare filament non-woven fabric with uniform texture, uniform thickness and uniform strength, and at present, no technology can be available.
The processing technology of the needle-punched non-woven fabric disclosed in CN 103290616 a adopts a 7-8 layer lapping mode to realize stacking, and the nylon spun-bonded filament non-woven fabric disclosed in CN102776710A and a preparation method thereof are dry spinning, fiber filaments are obtained through the dry spinning, then an airflow stretching tube is adopted, lapping is carried out after the fiber filaments are stretched in an airflow stretching mode of a stretching channel, firstly, how to lap the fiber filaments is not specifically disclosed, secondly, the method is a needle-punched reinforcement mode, the filament non-woven fabric which is thinner and has certain strength is required to be prepared, the fiber filaments are scattered through the needle-punching mode, the mode is used in wet spinning, wet fiber tows output through a coagulating bath cannot enter the airflow stretching tube, and wet-laying cannot be realized.
The technology overcomes the defect that the conventional filament non-woven fabric cannot be prepared by directly lapping fiber filaments, but the key factor of the technology is that wet fiber filaments prepared by wet spinning are uniform sheet-shaped fiber webs after entering a net curtain, and the thickness of the wet fiber filaments is uniform, so that the non-woven fabric obtained by spunlacing is uniform in thickness and uniform in strength.
Therefore, in order to prepare the filament non-woven fabric by directly lapping filaments prepared by a wet spinning technology, the wet spinning direct stacking lapping must be realized, the prior art has no record, the filaments prepared by the dry spinning technology are used for preparing the non-woven fabric, the short fiber multilayer lapping mode is not suitable for the wet spinning, and the mode of needling by air draft of the dry spinning cannot be used in the field of spunlace reinforcement of the wet spinning filament fibers. How to form a uniform flaky filament fiber web by stacking filament non-woven fabrics obtained by wet spinning and realize uniform lapping is the key of the technology and is a difficult problem to be solved urgently in the technical field at present.

The frame 10 is provided with a first guide rail 18 connected with the forming support plate 16 for guiding the forming support plate 16 to reciprocate on the frame 10 along the axial direction of the driving forming roller 14 and the driven forming roller 15, and a first hydraulic system for driving the forming support plate 16 to reciprocate, wherein the hydraulic system is arranged inside the device and is not shown, and the technology is well known to those skilled in the art and is not explained much. First servo motor is connected with shaping layer board 16 through locating first motor cabinet 19 on shaping layer board 16, first motor cabinet 19 is fixed with shaping layer board 16 through first screw 20, and dovetail groove formula guide rail commonly used on the present lathe can be selected to first guide rail 18, operates steadily, and the maintenance volume is less, and the precision is high.
In order to improve the regularity of the sheet-shaped uniform fiber tows 3 when falling down and ensure the uniformity of the filament fiber net 8 crossly stacked on the net curtain 5, the output ends 21 of the driving forming roller 14 and the driven forming roller 15 are provided with guide grooves 22 for assisting the sheet-shaped uniform fiber tows 3 to swing and stack into a net, and the guide grooves 22 are fixed on the roller body supporting frame 17.
An inclination amount compensating mechanism 23 for pulling the sheet-like uniform fiber tow 6, which is in an inclined state when the web forming mechanism 13 moves, back and forth in the opposite direction to the web forming mechanism 13 is provided between the feed roller 4 and the web forming mechanism 13.

As shown in fig. 5, the inclination compensating mechanism 23 is provided to solve the problem of the occurrence of the disturbance, and when the driving forming roll 14 and the driven forming roll 15 move in one direction, the driving compensating roll 24 and the driven compensating roll 25 in the inclination compensating mechanism 23 move in the direction opposite to the moving direction of the driving forming roll 14 and the driven forming roll 15, thereby achieving the purpose of compensation.
It is to be understood that the above description is not intended to limit the present invention, and the present invention is not limited to the above examples, and those skilled in the art should understand that they can make various changes, modifications, additions and substitutions within the spirit and scope of the present invention.
