Abstract
The present invention provides short stroke after-spinning production process for hollow 3D curved short fiber and belongs to the field of chemical fiber production process and equipment technology. Compared with available technology, the present invention has short technological path, reduced number of equipment, smaller shop area, lower heat consumption and transmission energy consumption and thus raised competition predominance.
Description
Technical field:
The present invention relates to spinning process technical field behind the hollow three-dimensional crimp short fiber.
Background technology:
The present invention is a spinning process behind the short distance hollow three-dimensional crimp short fiber.The existing technology that is used for spinning behind the hollow three-dimensional crimp short fiber production all adopts water-bath, twice heating of steam; Three drawing machines, twice stretching.Again through folded silk machine; Get into crimping machine; The tension force arrangement; Refueling water; Cut off; Forward get into the technology of relaxation heat setting.It is long that prior art processes exists route, and board is many; Shortcomings such as energy consumption is high, labour intensity is big.And destroyed the three-dimensional crimp effect.The forward end to end arrangement of cutting machine and relaxation heat setting machine has more increased process route length; Cause capital construction, cost of equipment to strengthen.
Summary of the invention:
The objective of the invention is:
1, under the situation of guaranteeing the curling effect of hollow three-dimensional crimp short fiber, reduces board quantity to greatest extent; Reach the purpose that reduces cost of equipment.
2, under the situation of guaranteeing the curling effect of hollow three-dimensional crimp short fiber, shortened process length reaches the purpose that reduces capital cost to greatest extent.
3, under the situation of guaranteeing the curling effect of hollow three-dimensional crimp short fiber, reducing the heat energy transmission to greatest extent can consume, and reaches the purpose of energy-conserving and environment-protective.
Technical scheme of the present invention is such:
With endless tow through first, second, speed difference one-off drawing between two drawing machines reaches the fiber orientation degree, draw ratio is controlled between 2.3～3.6, and forms the best three-dimensional crimp effect of diving; Being controlled between 65～95 ℃ of water bath solution temperature; Add a thread guide at the rear in two drawing machine exits, so that the elimination of tensile stress; Cut off a section equipment: tension bracket, tensioner, refueling water machine, traction machine, cutting machine be placed on the platform and after move; Between below the over top of relaxation heat setting machine and the platform bottom, establish the single-revolution foraminous conveyer, short fiber is heated drying in the reverse course of conveying of fiber; The below of reverse foraminous conveyer discharging opening is provided with a pendulum silk machine short fiber is evenly put neat entering relaxation heat setting machine intensive drying typing.
What more than introduce is to spin the production technology scheme behind the short distance hollow three-dimensional crimp short fiber of the present invention.

The specific embodiment:
Design philosophy key of the present invention is: described is that endless tow 1 is reached the fiber orientation degree through one, two, two drawing machine 5, speed difference one-off drawing between 7, and forms the best three-dimensional crimp effect of diving; The control of 6 water bath solution temperatures is most important; A drawing machine 9, steam chest 8, crimping machine 11, folded silk machine 10 have been reduced; Rear in two drawing machines, 7 exits adds a thread guide 22, so that the elimination of tensile stress; Cut off a section equipment: tension bracket 12, tensioner 13, refueling water machine 14, traction machine 15, cutting machine 16 be placed on the platform 19 and after move; Between below the over top of relaxation heat setting machine 18 and platform 19 bottoms, set up single-revolution foraminous conveyer 20, short fiber is heated drying in the reverse course of conveying of fiber; The below of reverse foraminous conveyer 20 discharging openings is provided with a pendulum silk machine 17 short fiber is evenly put neat entering relaxation heat setting machine 18 intensive dryings typing.
Design philosophy key of the present invention is: described is that draw ratio with back spinning filament bundle 1 is controlled between 2.3～3.6.
Design philosophy key of the present invention is: described is that the solution temperature in the water bath is controlled between 65～95 ℃.
Design philosophy key of the present invention is: described is endless tow 1 reverse resilience after thread guide 22 can prevent to stretch, so that tensile stress is eliminated.
Design philosophy key of the present invention is: described is with moving behind the cut-out section equipment, and cutting machine 16 moves to the top of relaxation heat setting machine 18 tail discharging openings, and the short fiber after cutting machine 16 cuts off can be fallen on the reverse foraminous conveyer 20.
Design philosophy key of the present invention is: described is around reverse foraminous conveyer 20, to be provided with heat-insulation layer 21, and short fiber is heated drying in the reverse course of conveying of fiber; The below of reverse foraminous conveyer 20 discharging openings is provided with a pendulum silk machine 17, and short fiber is evenly put neat entering relaxation heat setting machine 18 intensive dryings typing.
