Abstract
The invention relates to a preparation method of a super bright super-simulation profiled PET (Polyethylene Terephthalate) fiber, comprising the following steps of: (1) drying, fusing and extruding a super bright PET fiber to form a fusant; (2) enabling the fusant to flow through profiled spinneret orifices to form filaments, wherein the profiled spinneret orifices are asymmetric three-leaf spinneret orifices, five-leaf spinneret orifices, seven-leaf spinneret orifices or nine-leaf spinneret orifices; and (3) carrying out cooling and low-temperature oiling on the filaments in sequence to finally form finished products, wherein the cooling process is asymmetric forced cooling, the height of a channel is less than 120 cm, the lateral blow cooling temperature is less than 12 DEG C, and the difference value of asymmetric leaf surfaces is 25-38 percent. The invention is suitable for preparing the super bright super-simulation profiled PET fiber with bendability and super simulation.
Description
Technical field
The present invention relates to the Textile Engineering technical field, refer more particularly to a kind of super light PET fiber preparation method that has.
Background technology
Polyethylene terephthalate (being abbreviated as PET) is mainly used in and makes dacron fibre (Chinese commodity is called terylene).This fibre strength height, its fabric wear is functional, is a highest kind of output in the synthetic fiber at present, and about 5,100,000 tons of world wide production in 1980 accounts for 49% of world's synthetic fiber total output.
Along with improving constantly of socio-economic development level and living standards of the people, people are more and more higher to the requirement superior, comfortableization of garment material.Super have characteristics such as light PET fiber is good because of its gloss sense organ, good hand touch, and market demand is increasing.Super have light PET fiber preparation method to comprise: adopting to surpass has light PET fibre section, forms melt after drying, the melt extruded; Make melt-flow form filament then behind spinneret orifice, filament is the final finished product that forms after supercooling and low temperature oil successively.Super snugness of fit, the flexibility that light PET fabric is arranged, very slide the fabric of natural fabrics such as the too late cotton in aspect, fiber crops, wool such as sense far away at especially lint sense.Make super snugness of fit, the flexibility that light PET fabric is arranged, especially lint sense, very slide the fabric of natural fabrics such as aspect such as sense and cotton, fiber crops, wool close, and then surpassing has light PET fiber must have flexible and super emulation concurrently.
In the textile fabric field, the flexible fiber of preparation all is to adopt bi-component, and adopts composite spinning technology, and wherein a kind of component is polyamide fibre mostly, and this kind method is owing to adopt two components, and its production cost is higher.One-component is super to have the method for the flexible fiber of light PET fiber production to yet there are no report for adopting.
Contain more siO owing to surpassing to have in the light PET fiber in addition
2Particulate will make the fiber with super emulation, has more highly difficult on preparation technology.
Summary of the invention
Technical problem to be solved by this invention is: a kind of preparation method who has the super bright super-simulation profiled PET (Polyethylene Terephthalate) fiber of flexible and super emulation concurrently is provided.
For addressing the above problem, the technical solution used in the present invention is: the preparation method of super bright super-simulation profiled PET (Polyethylene Terephthalate) fiber comprises the steps:
(1) employing is super light PET fibre section, forms melt after drying, the melt extruded;
(2) make melt-flow form filament behind special-shaped spinneret orifice, described special-shaped spinneret orifice is a kind of asymmetric three leaf spinneret orifices, five leaf spinneret orifices, seven leaf spinneret orifices or nine leaf spinneret orifices;
(3) the filament final finished product that forms after supercooling and low temperature oil successively, described refrigerating work procedure is asymmetric pressure cooling, wherein the path height is less than 120cm, and chilling temperature is less than 12 ℃ in the lateral blowing, and asymmetric page difference value is between 25%-38%.
The described super siO in the light PET fiber that has
2Addition be mass percent 1.2%～4.0%.
The invention has the beneficial effects as follows: super bright super-simulation profiled PET (Polyethylene Terephthalate) fiber has good bulkiness, spreadability and good resilience, can bend to the different number of degrees and bending radius according to the needs of back processing in 90～100 ℃ boiling water.After using it for fabric, fabric not only has characteristics such as the gloss sense organ is good, good hand touch, and the snugness of fit of fabric, flexibility, especially lint sense, also the fabric with natural fabrics such as cotton, fiber crops, wools is close very to slide aspects such as sense, is subjected to people's popular welcome.
