preparation example Construction

[0023] As for the preparation method of the fiber, besides the commonly used synthetic fiber spinning method, an air extrusion method may also be used.

[0024] The present invention will be better understood according to the description of the following examples, wherein the listed examples are for the purpose of illustrating the present invention rather than limiting it.

Embodiment 1

[0026] Available on the market with an apparent specific gravity of 0.15g / cc, an average particle size of 2μm, and a SiO content of 98%. 2 Silica spheres with smaller particle sizes are separated from the hollow silica spheres. The apparent specific gravity of the separated silica spheres is 0.18g / cc, the average particle size is 0.65μm, and 90% of the particle size is 1.3μm. And the maximum particle size is 2.2 μm.

[0027] The hollow spheres separated in this way are carried out masterbatch preparation process together with polypropylene resin, and the polypropylene masterbatch sheet (granule) that contains 10wt% hollow silicon dioxide sphere is prepared, and this polypropylene masterbatch sheet is then further combined with polypropylene resin Blending and spinning of synthetic fibers was performed to produce a 1.2 denier polypropylene yarn containing 1.5 wt% hollow silica spheres.

[0028] The relative density of the prepared fiber is 0.96, wherein the meaning of relative...

Embodiment 2

[0030] Polystyrene microspheres with uniform particle size were synthesized by emulsion polymerization, and the microspheres were separated from the emulsion ( figure 1 ). Then, TEOS (tetraethylorthosilicate) was hydrolyzed and coated onto the microspheres, which were then allowed to dry. The inner polystyrene was dissolved in dichloromethane to obtain hollow silica spheres ( figure 2 ). The hollow silica spheres have a uniform particle size and a diameter of 1.0 μm. In order to determine the shape of these silica particles, the particles were cut and observed. From the observation results, it can be seen that the silicon dioxide is a hollow sphere ( image 3 ).

[0031] The hollow spheres were subjected to the same process as in Example 1 to obtain a 1.2 denier polypropylene yarn containing 1.5 wt% hollow silica spheres. Its relative density is 0.94.

Abstract

The present invention provides a synthetic fiber containing hollow spherical particles, each of which is formed of any one selected from inorganic substances, organic substances, or a combination of both. This fiber has the advantage of low specific gravity, which effectively solves the problem of daily wearing.

Description

technical field [0001] The present invention relates to a synthetic fiber containing hollow spherical particles. More specifically, the present invention relates to a synthetic fiber characterized in that it is light in weight due to the hollow particles contained therein and has different functions depending on the substance constituting the hollow spheres. Background technique [0002] With the development of fiber technology, functional synthetic fibers have been developed with a variety of properties, such as far-infrared emission, antibacterial activity, antistatic function, UV protection, magnetism, deodorization function, electromagnetic wave shielding performance, etc., which are beneficial to human beings. performance. In particular, synthetic fibers having some of the properties described above have been successfully produced and are currently commercially available. [0003] In order to obtain fibers having the above-mentioned properties, various methods have be...
