Description
Technical field
The present invention relates to a kind of apparatus for melt spinning, concrete is a kind of many components apparatus for melt spinning of efficient, short flow process that has been equipped with the single screw extrusion machine of the first measuring pump and has been equipped with the double screw extruder combination of booster pump and the second measuring pump, belongs to textile machine equipment class.
Background technology
Melt spinning machine is a kind of machine that makes fibre-forming polymer melt or gel-forming filiform, its topmost part is spinning system, and general spinning system comprises: chip drying, screw extruder, melt pipe, spinning manifold, measuring pump and transmission device, filament spinning component, blowing device, oiling device, spinning shaft, spinning control system, coiling panel, draw-off godet, winding head, winding control system.High polymer section is melted and is advanced and sent into spinning manifold through melt pipe by screw rod after hopper enters screw extruder.Melt is delivered to spinning head (plate) through Spinning pumps metering in casing, and the melt thread of being extruded by spinneret orifice runs into chilled air cools and is solidified into fiber in spinning window, after oiling, by winding mechanism, is wound on bobbin.
More melt spinning machine adopts single screw rod to advance and extrudes feeding at present, it is fast that feeding speed is extruded in single screw rod propelling, be generally used for the melt spinning of single polymer, during for multicomponent polymeric blend, need in advance blend to be mixed, or in advance by the blend of multicomponent polymeric through the granulation of double screw extruder blending extrusion, then the blend mixing or the pellet that obtains through double screw extruder extruding pelletization are placed in to the single screw extrusion machine of spinning machine, the feeding of pressurizeing.If be only, the blend of multicomponent polymeric is mixed to the single screw extrusion machine that is just placed in spinning machine, shape due to the polymer of different component, size, and the difference of density, the blend that causes originally mixing is started to produce in single screw extrusion machine to the gradient difference of the component ratio of polymer along with the rotation of single screw rod, thereby cause appearing at the component of polymer melt of spinning manifold not quite identical in different time sections, final spinning machine the component of spun fiber, sometimes even can have influence on the structure of fiber, as degree of crystallinity etc., also change to some extent, then various performances to fiber, as dyeability etc. causes comparatively significantly difference, had a strong impact on fiber quality.If be the single screw extrusion machine that pellet that the blend of multicomponent polymeric is obtained through double screw extruder extruding pelletization is placed in spinning machine, the feeding of pressurizeing, caused the post bake pressurization of polymer, easily cause the degraded of the polymer of hot pressing sensitivity or oxidation, thereby cause the sharply decline of fibre property, seriously restricted the kind of fiber and the development of fibre technology.
In order to solve the difficulty running in bicomponent fiber technology of preparing in melt spinning, in disclosed document, mentioned the method for loading two single screw extrusion machines on composite spinning machine, two kinds of different polymer are added respectively in extruder separately and prepare islands-in-sea bicomponent fibre.For example: China Patent Publication No. CN 1382844A, open day is on December 4th, 2002, name is called technology for spinning superfine islands-in-sea bicomponent fibre, a kind of technology for spinning superfine islands-in-sea bicomponent fibre is disclosed, that the screw extruder that dacron polyester is cut into slices and low melting point polyester chip enters respectively is separately heated, extrude, melting, become can spinning melt, by melt pipe, enter respectively main box measuring pump, auxiliary box body measuring pump, be evenly distributed in each filament spinning component, in filament spinning component, dacron polyester melt and low-melting point polyester melt mix, and from spinnerets, spray tow.China Patent Publication No. CN 11844506A, open day is on October 11st, 2006, name is called the production method of island type composite industrial yarn, disclose a kind of polyester and made island component, polyamide is made the production method of the compound silk of sea component, employing melt extrudes island component polyester and sea component polyamide respectively in screw extruder separately, polyester after melting and polyamide melt are respectively after measuring pump metering, enter in composite spinning machine, by the desk-top island of overall convex composite spining module, spin island type composite industrial yarn.China Patent Publication No. CN 102168321A, open day is on April 9th, 2011, name is called the manufacture method of islands-in-sea bicomponent fibre, a kind of manufacture method of islands-in-sea bicomponent fibre is disclosed, apply the twin-screw sea-island-type composite spun equipment that two single screw extrusion machines form, adopt twin-screw sea-island-type composite spun method, make the island phase component of melting be divided into multiply thread through sea-island-type composite spun plate, in spinneret orifice porch, by the marine facies component of melting, wrapped up, together extrude tow.The patent that the melt spinning machine that same employing is equipped with two single screw extrusion machines is prepared composite fibre also has China Patent Publication No. CN 101215734A, and open day is on July 9th, 2008, and name is called island type polyamide 6 fibre and preparation method thereof; China Patent Publication No. CN 102181953A, open day is on March 30th, 2011, name is called a kind of spinning technique of efficient bull composite ultrafine fiber; China Patent Publication No. CN 102704021A, open day is on October 3rd, 2012, name is called manufacture method and the composite spining module thereof of ferris wheel type island composite short fiber.
Although the disclosed technical scheme of above application case is all to use the composite spinning machine of twin-screw, but the twin-screw in spinning machine is to be present in respectively in two extruder sleeves, actual effect is the same with one pack system spinning machine, and be not suitable for two kinds of incompatible component co-blended spinnings, in order to address this problem, there is document to mention to melt composite spinning machine and be equipped with a double screw extruder.China Patent Publication No. CN 2915893Y for example, open day is on June 27th, 2007, name is called a kind of melt blending spinning machine of preparing alloy fiber, extruder to be designed to top connect the double screw extruder with the material storage tube of agitator, thereby reduce the size of decentralized photo, improve the distribution of decentralized photo.
In sum, although a lot of research is devoted to prepare islands-in-sea bicomponent fibre by designing new spinning system, but be all that two components that form islands-in-sea type fibre are formed to islands-in-sea bicomponent fibre through different extruder and composite spining modules respectively, or by all components put into a double screw extruder together melt blending extrude through filament spinning component and form composite fibre.The former is difficult to realize the blend of two kinds of incompatible components, two kinds of components of melting are prone to interfacial separation phenomenon after composite spining module, cause the decline of composite fibre mechanical property, the latter puts into same extruder by various ingredients, the structure of uncontrollable composite fibre, such as obtaining the fibers such as skin-core structure, tangerine valve structure.
