Abstract
The invention relates to the technique to produce 3D hollow crimped staple. The working procedures include follows: sequeezing out melted polyester or polyolefine from spinneret, blowing cold air on the side of extrusive thread, drawing the said thread in hot water or hot air, cutting off the thread into staple with length of 30-80 mm, and drying the said fiber. The procedures provide the features as follows: the speed of blowing cold air is 1.8 m/s-4.2 m/s with thread from spinneret being cooled; the mentioned thread is elongated to 2-4 times of original one when it being drawn. It has good elasticity.
Description
The present invention relates to the manufacture craft of the doughnut of a kind of polyester fiber, particularly a kind of three-dimensional crimp.
In the prior art, patent of invention as Chinese patent 88107859.X, it provides a kind of spinnerets of making doughnut, the filament that this spinnerets sprayed is straight type, although mentioned the method that is made into crimped fibre in this document and be in stuffer box crimper, carry out Texturized, but the fiber of making is in one plane crooked as zigzag, the poor flexibility of this fiber.
The object of the present invention is to provide a kind of manufacture craft at the curling many hollow three-dimensional crimp staple fibre of three dimensions.
Technical scheme of the present invention is: a kind of manufacture craft of many hollow three-dimensional crimp staple fibre comprises following operation:
(1), with the fusing polyester or polyolefin push out the filament that forms hollow by a plurality of spinneret orifices on the spinnerets, the filament of described hollow refers to be provided with a plurality of pipelines separately along the length direction of fiber;
(2), at the side blowing cold air of the silk of ejection, make the filament cooling of ejection, form the fiber that contains a plurality of ducts in the every monofilament;
(3), in hot water or hot-air, described silk is stretched;
(4), to be cut to length be 30 to 80 millimeters staple fibre to the silk after will stretching;
(5), carry out fiber is dried processing;
In operation to the filament cooling that spinnerets sprayed, in described spinnerets 5 to 20 centimeters of distance, filament to be cooled off with cold air, the speed that blows out of described cold air is 1.8 meter per second to 4.2 meter per seconds; In stretching process, to 2 to 4 times of the disposable elongations of described fiber.
The present invention compared with prior art has following advantage:
In the prior art, when the silk that sprays being cooled off with cold air, it generally is 0.6 to 0.8 meter per second that air blows out speed, and the speed that blows out of cold air of the present invention is 1.8 meter per second to 4.2 meter per seconds, filament one side of fusing is cooled off rapidly, for bigger internal stress has been reserved in three-dimensional crimp afterwards.Generally carry out at least twice stretching in the prior art, the big molecules align difference of fiber both sides is significantly reduced.But the present invention only carries out one-off drawing, can keep filament both sides macromolecular structure in the difference that reaches in the arrangement in the crystallization, for the three-dimensional crimp of fiber afterwards creates conditions as far as possible.After fiber was dried processing, fiber was heated the back because the molecules align of its both sides is variant, therefore can produce asymmetric retraction, forms the fiber of three-dimensional crimp, the shape spring-like that it curls, so its elasticity is good.
Embodiment:, a kind of manufacture craft of many hollow three-dimensional crimp staple fibre, comprise following operation:
(1), polyester or the polyolefin with fusing pushes out the filament that forms hollow by a plurality of spinneret orifices on the spinnerets, the filament of described hollow refers to be provided with a plurality of pipelines separately along the length direction of fiber, the volume in the duct in the described fiber account for whole fiber volume 20% to 30%.；
(2), at the side blowing cold air of the silk of ejection, make the filament cooling of ejection, form the fiber that contains a plurality of ducts in the every monofilament;
(3), in hot water or hot-air, described silk is stretched;
(4), to be cut to length be 30 to 80 millimeters staple fibre to the silk after will stretching;
(5), fiber is dried processing, the fiber of formation three-dimensional crimp;
Wherein, in the operation that the filament to the spinnerets ejection cools off,, filament is cooled off with cold air in described spinnerets 5 to 20 centimeters of distance, the speed that blows out of described cold air is 1.8 meter per second to 4.2 meter per seconds, and the temperature of cold air is that 22 degree Celsius are to 28 degree.In stretching process, be that 60 degree Celsius are to the conditions of 80 degree, to 2 to 4 times of the disposable elongations of described fiber in the temperature of hot water or hot-air.
Claims (4)
