By adopting the bi-component spunbonded spinning manifold with the above structure, the temperature can remain in a spinning process window of high polymer and can be stable when melt reaches micropore outlets for spinning components; the bi-component spunbonded spinning manifold has the benefits as follows: the structure is simplified and compact, the size is decreased obviously, the cost and the energy consumption are reduced correspondingly and so on; and the bi-component spunbonded spinning manifold is suitable for composite spinning of high polymer such as PP (Polypropylene), PE (Polyethylene), PET (Polyethylene Terephthalate), PLA (Poly Lactic Acid), PA (Polyamide) and the like, and can spin composite yarns in the shapes of skin-core, orange sections and the like.
Description
Technical field
The utility model relates to the production equipment of composite spunbonding process non-weaving cloth, and relating in particular to wherein can be with two kinds of different high polymers at the device of on a direction, evenly seeing off under the molten state, common name bicomponent spunbond method spinning manifold.
Background technology
The equipment and the technology of present composite bicomponent (multicomponent) spun-bonded non-woven, used spinning manifold are to adopt the casing type of chemical fibre composite spinning basically, and promptly two tanks or three casings only are to amplify or change shape.Investigate the production of spun-bonded non-woven and the production process of chemical fibre silk; Obviously the spinning equipment of spun-bonded non-woven need hold more fiber in littler area; Though thereby adopt through amplify or distortion, transplant in the two tanks or three casings of chemical fibre spinning and can satisfy the demand, on the reasonability of device structure, obviously use casing not as chemical fibre, the volume of equipment is huger; Cost is higher, the demand of incompatibility spun-bonded non-woven development.And the order ground that in producing bicomponent composite fibre, adopts two tanks or three casings is in order to eliminate influencing each other of two kinds of polymer different process temperature, to guarantee that temperature, the viscosity of each component keeps certain.But in fact after neither synthermal component gets into filament spinning component, inevitably can produce heat transmission; Also can not avoid hot generation of transmitting even reduce the time that produces the heat transmission again; Therefore, it is one of key technology that guarantees product quality that temperature, the viscosity that guarantees each component remains in certain scope.
Summary of the invention
The utility model technical problem to be solved is: a kind of bicomponent spunbond method spinning manifold is provided; This casing is single casing; Can two kinds of different high polymers evenly seen off on a direction under the molten state, and can guarantee the remaining in the spunbond processing technology window of temperature, viscosity stabilization of each component.
The technical scheme that the utility model adopted is: a kind of bicomponent spunbond method spinning manifold; Comprise the casing body; Said casing body is single casing; The casing body is provided with the casing zone of heating outward; Be provided with the first component melt flow channel and the second component melt flow channel of two groups of separate settings in the casing body, the first component melt flow channel and the second component melt flow channel are provided with the discharging opening that a charging aperture and a group are arranged along the width of non-weaving cloth separately, the capacity of said runner be the time of staying of melt in the casing body less than/equal 300 seconds.
The further technical scheme of the utility model is: the said first component melt flow channel and the second component melt flow channel are tubular structure, comprise metal tube or the pipeline that on metal derby, processes.
The beneficial effect of the utility model: adopt the spinning manifold of said structure, two kinds of melts are flowed in the casing that a control temperature is only arranged, and at each melt of fabric width direction uniform distribution of nonwoven fabric.Melt has heat transmission in this list casing; But melt-flow is enough short through the time of casing; Can guarantee that when melt arrives the micropore outlet of filament spinning component temperature still is in the spinning technique window of this high polymer and keeps stable temperature, can obtain the product of excellent machinability.And with two tanks or three casing bi-component casings relatively, designs simplification, compactness, volume significantly reduces, the corresponding reduction of cost and energy consumption.Be applicable to the composite spinning of high polymers such as PP, PE, PET, PLA, PA, can spin the compound silk of type shapes such as core-skin, tangerine lobe.
