Description
Technical field
What the present invention relates to is a kind of variation of hot adhesion at random shape long filament, especially will cause the changing profiled filament of fibre section shape along continuous change of the bonding point of the vertical blocking under warming at random of fiber by three viscous state flat filaments of spinnerets three slits ejection, belong to chemical fibre manufacturing technology field.
Background technology
The invention of chemical fibre and developing history are exactly that people use science and technology, imitate, substitute, surmount the history of natural fabric.Chemical fiber filament length can be made endless, and keeps line density, monofilament vertical structure, monofilament cross sectional shape, the filament properties of monofilament to remain constant.These have all surmounted the technical characterictic of natural fabric.Chemical fibre cross section by round spinneret orifice spinning is circular, also is that present purposes is the widest, the kind of output maximum.The chemical fibre with special cross section shape by non-round spinneret orifice spinning claims profiled filament.Profiled filament is for circular fiber.It is to form with the spinneret hole extruding ejection cooling curing that special geometry is arranged, and makes the cross section be the fiber of certain geometrical shape.As natural fabric, make that they are triangular in shape, T font, cross, Y shape, leafy shape etc.The character of profiled filament is different and different with cross sectional shape and degree of profile DR's (%) radially.The characteristic of profiled filament is high resilience, phozy balling-up, and bulkiness, spreadability and the anti-fouling effect of height arranged.Also can improve the drapability of its fabric and wrinkle resistance etc.
In recent years, the variety development of profiled filament was rich and varied increasingly extensive with application.Profiled filament is broad market prospect in clothing, decoration and fabrics for industrial use three big fields, also is the desirable feedstock of non-weaving cloth and imitation leather coating.But no matter being circular wire or non-circular silk, is whole synnema or monofilament, on the length of endless, all keeps unalterable as the line density of whole synnema, the monofilament radical (f number) of whole synnema along fiber axis.In the whole synnema each monfil structure, monofilament profiled cross-section shape, monofilament abnormity radially degree of profile DR (%), monofilament linear density etc. all keep unalterable, fiber lacks and enriches changeable stereochemical structure, the fiber species dullness is abundant inadequately.
Summary of the invention
The objective of the invention is to overcome the deficiency that existing spinning shaped filaments technology exists, and the variation of the blocking under warming at random shape long filament that provides a kind of fiber to have changeable stereochemical structure and colorful, applied range wide in variety, it is will be by the flat monofilament of three expanded shapes of viscous state of spinnerets three slits ejections, by the cooling air of disturbance and the filament spinning component melt pressure of circulation change, make along continuous change of the bonding point of the vertical blocking under warming at random of monofilament and cause the changing profiled cross-section monofilament in monofilament cross section.The shape of profiled cross-section that vertically is meant monofilament along monofilament is flexible, and radially degree of profile DR (%), monofilament linear density, monofilament radical (f number), vertical three-dimensional structure of monofilament, the physical property of monofilament etc. are all at random and strain for monofilament simultaneously.
The objective of the invention is to finish by following technical solution, this variation shape long filament along the fibre structure on the length of the axial endless of long filament, total linear density, monofilament linear density, monofilament radical, monofilament cross sectional shape, monofilament radially degree of profile DR%, monofilament 3 d shape structure, monofilament physical properties all owing to the variation of process conditions is adjusted to changed conditions.
Described variation shape long filament is to supply spinning melt by melt metering pump by the setting cycle control and regulation, and spinning silk winding speed is constant, causes long filament total linear density, the also cyclically-varying of monofilament linear density of spinnerets ejection; Because the variation of filament spinning component melt pressure changes the expansion amplitude of the superpolymer elastomer of spray silk slit ejection, touch mutually and bond state is done reliable bonding, unreliable bonding, the non-caked and regular cyclically-varying of monofilament radical at least.
70mm to 120mm position is provided with the swing cooling air vertical with the fiber movement direction under spinnerets, this swing cooling air is made periodic disturbance clocklike just from the superpolymer elastomer of spray silk slit ejection by setting, cause bonding point to be in the labile state of disturbance swing, the position that is bonding point is becoming at random, bonding cross section situation is various, and monofilament linear density, monofilament radical, monofilament cross sectional shape are also becoming synchronously at random.Described spinnerets includes one long two short three spray silk slits, from the wherein cyclically-varying of the bond state of the superpolymer elastomer of ejection, article three, line density is different again, each shrinkage factor during the bonding cooling curing is also different, the fibrous inside stress after the bonding and the power that involves are mutually also becoming at random, cause to become shaped filaments shape structure in the shape of a spiral, the left-handed sometimes dextrorotation sometimes of the hand of spiral, fiber directly has song sometimes, and the fiber plane is recessed sometimes protruding sometimes.
Superpolymer elastomer by a length two short three spray silk slits ejections can be boning at random mutually of same component material, it also can be the compound bonding at random of two kinds of performance different component materials, especially the compound of two kinds of shrinkage different component materials bonds at random, and 3D shape has more colourful stereoeffect.
Because it is different from three (one long two is short) high polymer line densities of spray silk slit ejection, cooling is shunk also different, the fibrous inside stress after the bonding and the power that involves are mutually also becoming at random, cause and become shaped filaments shape structure in the shape of a spiral, the left-handed sometimes dextrorotation sometimes of the hand of spiral, fiber directly has song sometimes, the fiber plane is recessed sometimes protruding sometimes, the physical property of monofilament and 3D shape etc. make between the monofilament of a branch of multifilament and obtain colourful variation shape long filament along the fibre structure performance of the axial endless of monofilament all at random and strain.It has changeable stereochemical structure and colorful, applied range wide in variety, and manufacturing technique is simple, and cost of manufacture is low, characteristics such as the good product quality of manufacturing.
