Description
Technical Field
The utility model relates to a short-staple makes technical field, concretely relates to heterotypic cavity polyester staple fiber.
Background
Profiled fibers have a large surface coefficient, whereas the surface coefficient = fiber cross-sectional perimeter/fiber denier (1 denier =1.1 dtex). The surface coefficient is large, the void ratio among fibers is large, so the bulkiness of the yarn fabric is high, the special-shaped section fibers have special luster, bulkiness, stain resistance and pilling resistance, and the resilience and the covering performance of the fibers can be improved.
In order to better improve the resilience of the short fiber and enable the fiber to have higher toughness, the original appearance can be recovered better and faster when the short fiber is twisted by a large force, and therefore, the structure of the profiled short fiber is better improved.
Disclosure of Invention
For solving the not enough of prior art, the utility model aims to provide a heterotypic cavity dacron short-staple, simple structure makes the fibre have stronger resilience effect.
In order to achieve the above object, the utility model adopts the following technical scheme:
a profiled hollow polyester staple fiber is characterized in that: including fibre web, short fabric and diversion bent axle, the short fabric encircles the top layer that sets up at the fibre web, the diversion bent axle sets up the middle part at the fibre web, the fibre web is provided with two-layerly, and outer fibre web bonds with short fabric, just the cross sectional shape of outer fibre web is circular, the inside of inlayer fibre web is hollow structure, the middle part of outer fibre web and inlayer fibre web is connected to the diversion bent axle, just the diversion bent axle encircles the middle part a week of outer fibre web, the top and the bottom both ends of diversion bent axle are all sunken to the middle part, form V type cross-section.
Preferably, the surface of the fiber net is of a net structure, so that the fiber net can better adapt to pulling and prevent deformation.
Further preferably, the fiber net is made of polyester materials and has high elasticity.
Further preferably, the pore diameter of the outer layer fiber net is larger than that of the inner layer fiber net, so that the outer layer fiber net is convenient to bond with a short fabric, and the fabric is plump.
Further preferably, the thickness of the inner layer web is 0.5 mm.
Further preferably, the turning crankshaft is made of polyester materials, and the same materials are adopted as the fiber nets, so that the integrity of the product is greatly improved, and fracture and splitting are prevented.
Further preferably, the minimum thickness of the turning crankshaft is larger than the thickness of the fiber net, so that fiber breakage is prevented, and use is prevented.
The utility model discloses an useful part lies in: through the setting of diversion bent axle, make the fibre web more have the resilience of high strength, be adapted to the torsion of different dynamics, greatly reduced the probability that the fabric warp, still through network structure's setting, make this kind of heterotypic polyester staple fiber have stronger elasticity, improved fibrous life greatly.
Drawings
Fig. 1 is a schematic structural diagram of the present invention;
the meaning of the reference symbols in the figures:
1 is an inner layer fiber net, 2 is an outer layer fiber net, 3 is a turning crankshaft, and 4 is a short fabric.
Detailed Description
The invention will be further described and illustrated with reference to the following examples and figures, without restricting the invention in any way.
As shown in figure 1, a heterotypic cavity dacron short-staple, including the fibre web, short fabric and diversion 3, short fabric 4 encircles the top layer that sets up at the fibre web, diversion bent axle 3 sets up the middle part at the fibre web, the fibre web is provided with two-layerly, outer fibre web 2 bonds with short fabric 4, and the cross sectional shape of outer fibre web 2 is circular, the inside of inlayer fibre web 1 is hollow structure, diversion bent axle 3 connects the middle part of outer fibre web 2 and inlayer fibre web 1, and diversion bent axle 3 encircles the middle part a week of outer fibre web 2, the top of diversion bent axle 3 all caves in to the middle part with bottom both ends, form V type cross-section.
The surface of the fiber net in the embodiment is of a net structure, so that the fiber net is better suitable for pulling and is prevented from deforming.
In the embodiment, the fiber net is made of terylene material with high elasticity.
The aperture of the outer layer fiber net 2 is larger than that of the inner layer fiber net in the embodiment, so that the short fabric can be conveniently bonded, and the fabric is plump.
The thickness of the inner layer web 1 in this example was 0.5 mm.
The direction-changing crankshaft 3 in the embodiment is made of the polyester material, and is made of the same material as the fiber net, so that the integrity of the product is greatly improved, and fracture and splitting are prevented.
The minimum thickness of the turning crankshaft 3 in the embodiment is larger than the thickness of the fiber web, so that the fibers are prevented from being broken and the use is prevented from being influenced.
The utility model discloses an useful part lies in: through the setting of diversion bent axle, make the fibre web more have the resilience of high strength, be adapted to the torsion of different dynamics, greatly reduced the probability that the fabric warp, still through network structure's setting, make this kind of heterotypic polyester staple fiber have stronger elasticity, improved fibrous life greatly.
The foregoing illustrates and describes the principles, general features, and advantages of the present invention. It should be understood by those skilled in the art that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by adopting equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
