Description
Technical field
The invention belongs to composite spinning equipment technical fields, and in particular to a kind of three component parallel composite fiber spinning groups
Part.
Background technique
Well known bicomponent composite fibre such as parallel type is washed, bright and beautiful bicomponent composite fibre has longer production in China and goes through
History and whether equipment or technique are very mature.It can be in disclosed Chinese patent literature about bicomponent composite fibre
It is seen in, such as a kind of core shift bicomponent composite fibre of CN101109110A(and preparation method thereof), using PPS and PBT, PBT and PA6
Or use PBT and PA66；CN101798714B(bicomponent composite fibre and preparation method thereof), using PBT and PA；
CN104195673B(bi-component polyester composite fibre direct fabrics method and system), using bi-component PBT.
Since above-mentioned bi-component composite fiber has good three-dimensional crimp performance, thus obtained extensively in knitting field
Application.But since the crimp radius of bicomponent composite fibre is relatively large, thus in the fiber crimp of certain length range
Quantity is restricted.
Three component parallel composite fibers are due to using into the fibrous raw material after fibre with different elongations, thus nascent fibre
Tie up it is stretched will generate three-dimensional crimp, and crimp radius is significantly less than bicomponent composite fibre, and simultaneously due to three components
Fiber crimp quantity of the column type composite fibre within the scope of certain length is significantly higher than bicomponent composite fibre, thus makes bi-component
Composite fibre can not compare favourably with the elasticity stood out from one's fellows and flexibility of three component parallel composite fibers.
Equally visible all technical information relevant to aforementioned three components composite fibre in disclosed Chinese patent literature, such as
CN1164810C(polyamide fine fibre and preparation method thereof), CN1185377C(polyaniline/polyamide conductive fibers and its preparation
Method), a kind of three-component fiber of CN101892536B(is blended and its manufacturing process), a kind of multiple groups part of CN101768796B(it is multiple
Close eccentric fiber and preparation method thereof), a kind of multi-component compound eccentric fiber of CN101798713B(and preparation method thereof),
A kind of preparation method of meta-aramid fibers of CN103233292B() and a kind of high anti pilling of CN105908268B(and high abrasion
Three component composite fibres and preparation method thereof), etc..
As is known in the industry, filament spinning component is the important component of complete spinning equipment, and can be in disclosed Chinese patent text
Be seen in offering, as CN103668499A(two-component wind spinning head), a kind of two-component composite spinneret group of CN206467344U(
Part), the spinneret structure of CN204509525U(polylactic acid bi-component composite fiber single spraying wire hole filament spinning component) and
CN103668498A(two-component is interlocked spinning head), etc..Aforementioned CN103668499A is that the fiber of two kinds of different materials is made to exist
Tangle up is glued by certain viscosity before solidifying；Aforementioned CN206467344U is to be bonded to each other two-component materials；It is aforementioned
What CN20450925U was applicable in is the spinning of two kinds of identical materials (polylactic acid)；Aforementioned CN103668498A can make two kinds of materials
Spun filament is interweaved but non-intersecting and form a branch of tow after ejection.
It is not limited to patent exemplified above and is not able to satisfy wanting of being evenly spaced on the fiber of two kinds of different materials
It asks and had not both provided directly or indirectly corresponding technical inspiration.
By the publication No. that the applicant proposes be CN108707987A, entitled " filament spinning components of bicomponent fibers " solve
Determined the problem of fiber of two kinds of different materials is evenly spaced on and faithfully fulfilled the 0021st section of specification remember
The technical effect of load.
By the reading to aforementioned CN108707987A, for objective, have for three component filament spinning components of design certain
Instructive, but since CN108707987A is for special-purpose such as pipe tobacco, thus what it pursued is two
Kind fiber such as acid fiber by polylactic and the distributing homogeneity of polypropylene fibre between the two, then in the structural body of composite spining module
It opens up the first spinneret orifice (patent claims " spinneret orifice I ") and the second spinneret orifice every one state with one on the spinneret of system (patent claims
" spinneret orifice II "), the first spinneret orifice and the first fused mass flow guiding of distribution plate hole phase on the melt distribution plate being located above spinneret
It is logical, the second spinneret orifice equally with the second fused mass flow guiding of distribution plate hole phase on the aforementioned melt distribution plate that is located above spinneret
Logical, the first, second spinneret orifice is in a distribution every one always, and obtained tow is the uniform silk union of two kinds of raw materials,
For each single acid fiber by polylactic also polypropylene fibre, relationship that the two is not bonded to each other (see
The 0040th section of the specification of CN108707987A).However, what is pursued by aforementioned three components parallel composite fiber is to make
Each fiber includes the composite fibre being made of three kinds of different materials to combine togather, for example, by PLA, PTT with
And PBT three is mutually bonded into one, or claims to stick to each other, since this tricomponent fibre can be not only used for and other fibre
It ties up blended, can also be used as filler, moreover it is possible to resultant yarn alone, thus compared with the favor by people.
Based on the above-mentioned evaluation to CN108707987A it is found that preparing aforementioned three components parallel composite fiber to meet
Requirement, then substantial improvement must be made to the structure of spinneret.
Although equally visible all related to the processing spinneret of three component composite fibres in disclosed Chinese patent literature
Technical information, as CN202610410U recommendation have " spinneret used in three-component composite fiber with special-shaped cross section " and
CN205803643U is provided with " be used to prepare three component profiled-cross-section composite hollows and glue fiber ", etc., but for being intended to set
The spinneret of the structural system for the three component parallel composite fiber filament spinning components that meter applicant is mentioned above does not have enlightenment
Meaning.Because if spinneret plate structure is lost rationally, then being difficult to obtain crimp radius as described above small, elastic and soft
Soft three excellent component parallel composite fibers, technical solution described below generate in this background.
Summary of the invention
Task of the invention lies in provide a kind of melt for helping to make three kinds of different spinning materials to pass through respective path
It arrives at after spinneret and realizes crimp radius that is compound outside hole and being able to be reduced significantly composite fibre outside the spinneret orifice of spinneret simultaneously
And it significantly enhances elasticity and flexibility, be conducive to ensure the terse property of structure and be able to facilitate production and embody relatively cheap effect
