Abstract
The invention relates to a preparation method of a colorful sea-island composite fiber. A sea component is soluble polyester; island components include polyester and polyamide; the fiber has the colorful effect by adjusting the distribution gauge between the two island components; the number of islands on a single fiber section is 16-1,000; and the islands are equal in area. The sea-island composite fiber is characterized in that two different island components are arranged on the single fiber section; the spaces of the different island components are not identical; and the colorful effect is reached by different optical effects generated between the fibers. The composite fiber can show good luster without dyeing; the color is kept stable; and the composite fiber is good in physical property and good in spinnability.
Description
Technical field
The present invention relates to the preparation field of islands-in-sea type fibre, particularly a kind of preparation method with the island-in-sea type composite fiber of dazzling color effect.
Background technology
Since the mid-90, luminescent fibre obtains to be applied more and more widely.At present, the preparation method of luminescent fibre has a lot, such as coating or interpolation luminous agent etc., but fiber prepared by these methods has luminosity low, poor durability, the defects such as unstable chemcial property, the more serious poison that also can have has radioactivity, and harmful, Application Areas is limited.
The present invention is intended to the internal structure by changing composite fibre, prepares different fibrous island-in-sea type composite fiber, thus makes the generation of this fiber dazzle color effect, and this fiber has, and illumination effect is good, good endurance, Stability Analysis of Structures, good physical performance, the advantages such as good spinnability.
Summary of the invention
The invention provides and a kind of there is the island-in-sea type composite fiber preparation method dazzling color effect, by changing island-in-sea type composite fiber internal physical structure, adopt two kinds of different fiber spacing change generations to dazzle color effect and dazzle color island-in-sea type composite fiber to prepare this, and have that luminescent effect is good, good endurance, Stability Analysis of Structures, good physical performance, the advantages such as good spinnability.For reaching this effect, the present invention adopts following scheme:
First aspect, the invention provides one and dazzle color island-in-sea type composite fiber, its marine origin is divided into soluble poly ester, and island component is polyester and polyamide two kinds.
Of the present inventionly dazzle color island-in-sea type composite fiber island component and select polyester and polyamide two kinds of island components, make its spacing not wait and produce luminescent effect, compared with the island component of one-component, it is more obvious that it dazzles color effect, and luminosity is better.
Of the present inventionly dazzle color island-in-sea type composite fiber without the need to dyeing, and color and luster is good, good endurance, compares luminescent additive safer stable, good physical performance, good spinnability.
In the present invention, described in dazzle color island-in-sea type composite fiber sea component and island component mass ratio be 60:40-40:60.Can be such as 60:40,55:45,50:50,45:55,40:60, be preferably 55:45-45:55.
Of the present inventionly dazzle color island-in-sea type composite fiber, on its single fiber cross section, the quantity on island is 16-1000, island area is impartial, for the arbitrary value in 2-200nm, preferred island area is that 2-100nm is preferably 500-1000 to island quantity, and the distance between surface, outermost layer island and fiber surface is 0.6-3.0 μm.
Of the present inventionly dazzle color island-in-sea type composite fiber, on filament cross section, island component is the distribution of different radii circular annular form, and circumferential island number is that even number is put to ensure to interlock in circumference (clockwise) and radial (left radius) two kinds of island components.
Of the present inventionly dazzle in color island-in-sea type composite fiber, in filament cross section, centered by island, the center of circle, in the circumference (clockwise) in its island component distributed areas and radial direction (left radius), the distribution of two kinds of island components is spaced and is become large gradually.
Of the present inventionly dazzle in color island-in-sea type composite fiber, the distance on filament cross section between each independent island component is at 10-1000nm.
Of the present inventionly dazzle color island-in-sea type composite fiber, the distance on its filament cross section between any two independent island components is different.
Beneficial effect of the present invention:
(1) preparation method of the present invention is simple, and cost is low, can be mass-produced.
(2) color island-in-sea type composite fiber that what the present invention obtained dazzle can present without the need to dyeing dazzles color effect preferably, safety and good endurance, Stability Analysis of Structures, good physical performance, good spinnability.
Accompanying drawing explanation
Fig. 1 spins this PLA Composite Fiber spinneret pore structure used.
In figure, broken circle and solid line circle represent polyester and polyamide two kinds of island components respectively; M, n and x, y represent radial (left radius) and the different distance between circumference (clockwise) polyester and polyamide two kinds of different island components in island component distributed areas respectively, represent that in filament cross section, any two independent island component spacings are all unequal.Island composition quality proportion optimization is 55:45-45:55, and island quantity is preferably 500-1000, and the distance between surface, outermost layer island and fiber surface is 0.6-3.0 μm.
Detailed description of the invention
For ease of understanding the present invention, it is as follows that the present invention enumerates embodiment.Those skilled in the art should understand, described embodiment is only help to understand the present invention, should not be considered as concrete restriction of the present invention.
Embodiment
It is as follows that this dazzles color island-in-sea type composite fiber preparation method
(1) with solubility polyester for sea component, with polyester and polyamide for island component.
(2) on the spinning machine that island composite spinneret is housed, carry out spinning, through melt spinning, it is 70 that false twisting processing obtains line density, and filament quantity is the island-in-sea type composite fiber of 36.
Embodiment 1-5
Obtain by composition quality proportioning in island described in above-described embodiment and preparation method and dazzle color fiber, concrete proportioning is as shown in table 1.
Comparative example 1-6
Composite fibre is obtained by preparation method described in above-described embodiment, but island composition quality proportioning is wherein adjusted, adjusts the sea component (solubility polyester) in embodiment and the shared mass percentage of island component (polyester and polyamide) respectively.Concrete compound is than as shown in table 1.
Table 1
The garment material of dazzling made by color fiber prepared by embodiment 1-5 and comparative example 1-6 is carried out brute force, elongation at break, ABRASION RESISTANCE etc. and take correlated performance test, and under equal dark condition, the fabric of different islands composition quality proportioning is observed it and dazzle color effect, can draw the following conclusions:
(1) this dazzles in color island-in-sea type composite fiber, and can be spun under strand part, shared by its sea component, mass ratio is larger, and its fibre structure is more stable, and physical property is better.
(2) this dazzles in color island-in-sea type composite fiber, and can be spun under strand part, shared by its island component, mass ratio is larger, and it is better that color effect dazzled by its fiber, and color and luster is brighter.
