Specific embodiment
In order to develop a kind of implant that can substitute eider down, the invention provides a kind of excellent fluffy processed filament being made up of polyester long fibre of bulkiness, wherein contain doughnut.According to IDFB test benchmark, the loft of this processed filament is 400inch3/ 30g～800inch3/30g.Loft numerical value is bigger, represents that the space of the air layer that processed filament is formed is bigger, heat-insulating property is better.Meanwhile, the higher feel of loft is more soft.
The fluffy processed filament of the present invention is made up of sheath fiber and two parts of core fibre, and sheath fiber and core fibre are all the long fibres being formed by polyester, by the jet-action of compressed air, sheath fiber and core fibre are intersected and sheath fiber formed outside core fibre circular.Due to the empty effect of pressure, the fibre bundle of sheath fiber is separately formed many ultimate fibres, and described sheath fiber passes perpendicularly through the multiple round annular that sheath fiber while core fibre bundle forms cross point constitutes 3 D stereo back and forth.What the cross point that sheath fiber and core fibre are formed not was fixed together melts point, but can move within the specific limits.When this fluffy processed filament uses as packing material, deformed by external force extruding, during deformation, the cross point of fluffy silk can occur certain displacement to absorb external force, after external force removes, again can significantly recoverability.
The filament number constituting the sheath fiber of fluffy processed filament is preferably 3.5dtex～10.0dtex.Although the flexibility of fiber increases if filament number is too thin, the voltage endurance capability of the annulus that sheath fiber is formed can decline on the contrary；Conversely, bigger the had rigidity of the filament number of fiber is higher, prepared fluffy processed filament will be partially hard, and feel is deteriorated.So the filament number that the present invention forms the sheath fiber of described processed filament is more preferably 4.0dtex～8.0dtex.
Preferred 30dtex～the 300dtex of total fiber number of described core fibre.
Sheath fiber is in the preferred 2mm～12mm of radius of the outer annulus being formed of core fibre.The fibroplastic circle diameter of sheath is too small, and the volume of the solid space of formation is just little, leads to the bulkiness of processed filament not, the medicated clothing after being filled with it or bedding are stronger, do not have the fluffy sense of eider down, heat-insulating property also can decline.Otherwise although the bulkiness of the bigger processed filament of the fibroplastic annulus of sheath and flexibility can improve a lot, but compression resistant performance can be deteriorated that is to say, that this processed filament is subject to external force can form permanent deformation when extruding, and leads to degraded performance.Sheath fiber is in the radius more preferably 4mm～9mm of the outer annulus being formed of core fibre.
Number preferably 30～150/cm in the cross point that described sheath fiber and core fibre are formed simultaneously.Intersect the intersection point of formation with core fibre after so-called cross point refers to sheath fiber detaching, but this intersection point does not melt together, can move freely.There is dependency in the number in cross point and sheath fibroplastic annulus number.The cross point of sheath fiber and core fibre formation is few, illustrates that sheath fibroplastic annulus number is few, then the bulkiness of processed filament is low；Conversely, the cross point that sheath fiber and core fibre are formed is many, illustrate that sheath fibroplastic annulus number is many, although then the loft of processed filament increases in certain limit, but the solid space of sheath fiber will not increase, the weight of processed filament unit length increases on the contrary, leads to loft to decline.Number more preferably 40～80/cm in the cross point that described sheath fiber and core fibre are formed.
The sheath fiber of fluffy processed filament of the present invention and core fibre can sheath fiber be individually doughnut, core fibre is solid fibers, or core fibre is doughnut in turn, sheath fiber is solid fibers it is also possible to sheath fiber and core fibre both doughnuts.The present invention preferred sheath fiber and core fibre both doughnuts.Compare with solid fibers, the density of doughnut is less, under same processing filament shapes and grammes per square metre, the length of the fluffy processed filament being obtained by doughnut is longer, is more beneficial for improving the fluffy performance of fluffy processed filament.But the too high doughnut of degree of hollowness has high demands to production technology, and productivity is low.In the present invention, the degree of hollowness preferably as sheath fiber and the doughnut of core fibre is respectively 20～50%, more preferably 25%～40%.
When core fibre is for solid fibers, its fracture morphology, in addition to circle, can also be the special-shaped sections such as triangle, cross, eight leaves.
Simultaneously in order to improve the loft of fluffy processed filament, the sheath fiber preferred curvature radius of the present invention be 5mm～20mm unwinding after helically 3 D stereo shape crimped filament, described radius of curvature is the radius of the unwinding rear screw of sheath fiber.If the radius of curvature of described sheath fiber is too little, it is difficult fibrillation in fluffy silk course of processing mesotheca fiber, and the diameter of annulus that sheath fiber is formed is less than normal, the bulkiness of impact processed filament；Conversely, if the radius of curvature of sheath fiber is too big, after being processed into fluffy processed filament, the fibroplastic circle diameter of sheath is excessive, can weaken or cannot embody the three-dimensional stereo effect of sheath fiber script.
Fluffy processed filament of the present invention can be prepared via a method which to obtain, but is not limited to the method：Sheath fiber and core fibre are fed respectively by different feeding rollers or feeding roller, the feeding speed of the adjustment sheath fiber and core fibre filament length difference to control sheath fiber and core fibre；According to the difference of sheath fiber, core fibre and bulkiness processed filament kind, the length of sheath fiber is 5～50 times with core fibre length.Air velocity at setting nozzle divides in 30L/～and 150L/ divides, and, with the nozzle that is drawn through of air-flow, then core fibre and sheath fiber form interlacing in jet expansion source with the effect of chaotic air-flow for sheath fiber and core fibre.Described confusion air-flow is to become chaotic by the flow direction that sheath fiber and core fibre cause the compressed air of single flow direction originally to the interference of compressed air, and this chaotic air-flow is in cyclically-varying, sheath fiber carries out fibrillation with chaotic air-flow, and core fibre forms periodic intersection, forms fluffy processed filament.
In order to improve the flexibility of processed filament further, can be with the softening agent of attached last layer silicon systems on the surface of fluffy processed filament.According to the difference of sheath fiber and core fibre surface area, silicone oil adhesion amount is also different, and the adhesion amount scope of the purposes difference softening agent according to fluffy silk is 0.1wt%～5.0wt% simultaneously.
The loft of fluffy processed filament of the present invention is high, soft, and due to being the fluffy silk that long fibre is constituted, the heat insulating products such as the clothes made, quilt have the advantages that not leak floss, do not bore floss.
