Abstract
The utility model relates to a three-dimensional hollow polyester staple fiber. The three-dimensional hollow polyester staple fiber is in a C shape. The external diameter of the C shape is 1.9mm, the inner diameter of the C shape is 1.4mm, and the length of a silk spray micropore is 1.9mm. The three-dimensional hollow polyester staple fiber has the advantages of properly increasing a length-diameter ratio, increasing from 1.5mm to 1.9mm in length, ensuring reasonable swelling ratio of sprayed melt flow, maintaining proper hollow ratio of fibers, increasing from 1.8mm to 1.9mm in the external diameter, enabling wall thickness of hollow fibers to increase, improving rebound resilience, then improving bulky character index of the fibers, and obviously improving rigidity and resistance of pressure of the fibers.
Description
[technical field]
The utility model relates to the fibre technology field, specifically, is a kind of three-dimensional hollow pet staple fiber.
[background technology]
Present domestic one-component doughnut factory, all using spinneret orifice is that the spinnerets of " C " shape is produced the Three-dimensional crimped hollow polyester staple fiber.Polyester fondant is flowed through after hollow profiled " C " shape spinneret orifice extrudes, adopt the blowing of high-speed low temperature ring to as-spun fibre quenching fibroblast, the precursor microstructure of asymmetric cooling presents anisotropy, produce asymmetric supramolecular structure on the strand cross section, behind this unsymmetric structure cooling forming, precursor inside will hidden a kind of naturally curling potential energy in the hiding, under the effect of first break draft at suitably draw ratio and draft temperature, make the low part generation molecularly oriented of precursor birefringence and degree of crystallinity, another part that birefringence and degree of crystallinity are higher produces excessively and stretches, reverse around axial generation owing to two kinds of different contractions of supramolecular structure part, form spirality three-dimensional naturally curling, through relaxation heat setting, make and curlingly manifest fully, improve simultaneously fiber mechanics character, stable fibers length, easy to use.
The doughnut product spins industry as family and fills raw material, have the thermal property that is better than cotton, bulk performance, compression resilience and gas permeability, substitute cotton and sponge, be used for the filling of quilt, pillow, mattress and toy etc., thereby require very high to resilience and the bulkiness of fiber.
[utility model content]
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of three-dimensional hollow pet staple fiber is provided.
The purpose of this utility model is achieved through the following technical solutions:
A kind of three-dimensional hollow pet staple fiber, described staple fibre is shaped as the C font, it is characterized in that, and the external diameter of described C font is 1.9mm; The internal diameter of described C font is 1.4mm.
The length of described spinneret orifice is 1.9mm;
Compared with prior art, good effect of the present utility model is:
Suitably increased draw ratio, length increases to 1.9mm by original 1.5mm, guarantees to spray the rational expansion rate of melt thread, keeps the suitable hollow rate of fiber; External diameter increases to 1.9mm by 1.8mm, and the wall thickness of doughnut is increased, and resilience improves thereupon, thereby improves the bulky character index of fiber, and rigidity and the resistance to pressure of fiber obviously strengthen.
[description of drawings]
The micropore figure of Fig. 1 fiber of the present utility model;
The shape figure of Fig. 2 fiber of the present utility model.
[specific embodiment]
The specific embodiment of a kind of three-dimensional hollow pet staple fiber of the utility model below is provided.
Embodiment 1
See also attached Fig. 1 and 2, a kind of three-dimensional hollow pet staple fiber is characterized in that described staple fibre is shaped as the C font;
The external diameter of described C font is 1.9mm;
The internal diameter of described C font is 1.4mm;
The length s of described spinneret orifice is 1.9mm;
The utility model adopts C font spinnerets by conventional melt-spinning technology preparation; The external diameter of described C font is 1.9mm; The internal diameter of described C font is 1.4mm; The length of described spinneret orifice is 1.9mm.
The above only is preferred embodiment of the present utility model; should be pointed out that for those skilled in the art, without departing from the concept of the premise utility; can also make some improvements and modifications, these improvements and modifications also should be considered as in the protection domain of the present utility model.
