Problems solved by technology

It is disclosed in the prior art of the above-mentioned patent application that in the case of a C-shape including one slit, due to the part separated between the slits, the amount of air inflow is small so that the hollow ratio is not high, and even if the hollow ratio is increased, the Due to the thin outer wall of the raw silk, the strength and other physical properties of the fabric are reduced
Also, in the case of the above-mentioned patent application, there is a problem that the eluting type hollow fiber is not prepared by composite spinning, but the hollow fiber is formed by solidifying the polyester after spinning, so that in the production The hollow fiber with a high hollow ratio is limited, and even if it is produced, it cannot ensure the strength that can pass through the production process, which will reduce the spinning workability, or the hollow of the hollow fiber will be deformed and destroyed in the post-processing process and / or weaving process.
Furthermore, in the case of the above-mentioned patent application, the hollow fiber is produced through a spinneret having a plurality of slits, and there is a problem that the strength of the prepared hollow fiber is further reduced.

preparation example Construction

[0222] On the other hand, the fourth example of the present invention includes a fabric including the C-shaped composite fiber of the first example of the present invention as described above. The preparation method of the fabric includes: step (1), preparing C-shaped composite fibers; and step (2), including the above-mentioned C-shaped composite fibers for weaving or weaving, thereby preparing the fabric.

[0223] The above-mentioned fabric may only include the C-shaped composite fiber of the present invention, or may be interwoven or interwoven with other types of fibers. The specific description of the above-mentioned fourth example is as above, so in the following description, corresponding content will be omitted.

Embodiment 1

[0226] First, to prepare the sheath, polyethylene terephthalate was melted at 290° C. with the polyester-based fiber-forming component contained in the sheath. And, in order to prepare the core, terephthalic acid and ethylene glycol compound were adjusted to a molar ratio of 1:1.2, and relative to the total number of moles of terephthalic acid and dimethyl isophthalate sulfonic acid sodium salt, 1.5 mole percent adjusted dimethyl sulfonate isophthalate sodium salt. As a catalyst, based on 100 parts by weight of sodium dimethyl sulfonate isophthalate, 10.0 parts by weight of lithium acetate (lithium acetate) was mixed, and the esterification reaction was carried out at a temperature of 250°C and a pressure of 1140 Torr to obtain The ester reactant has a reaction rate of 97.5%. The formed ester reactant is transferred to a polycondensation reactor, wherein, with respect to 100 parts by weight of the ester reactant, after adding 10.0 parts by weight of polyethylene glycol with a...

Embodiment 2 to Embodiment 4

[0233] Prepared by the same method as in Example 1, the weight ratios of the sheath and the core were respectively 60:40, 50:50, and 40:60 to carry out composite spinning. Composite fibers, hollow fibers and fabrics.

Abstract

The present invention relates to a C-shaped composite fiber, a C-shaped hollow fiber thereof, a fabric including the same, and a method for manufacturing the same and, more specifically, to a C-shaped composite fiber, a C-shaped hollow fiber thereof, a fabric including the same, and a method for manufacturing the same wherein a hollow rate is improved and at the same time, excellent solidity and ductility is retained such that the composite fiber and / or the hollow fiber do or does not deform easily during a manufacturing process, quality degradation of the hollow fiber is minimized during an elution process, a reduction process is not necessary in a fabric state when manufacturing the fabric, and the manufactured fabric can have excellent thermal insulation and lightness.

Description

technical field [0001] The present invention relates to a C-shaped composite fiber, a C-shaped hollow fiber passing therethrough, a fabric containing it, and a preparation method thereof, and in more detail relates to a C-shaped composite fiber, a C-shaped hollow fiber passing therethrough, a fabric containing it and its preparation method The preparation method has an improved hollow ratio, and has excellent strength and elongation, so that in the preparation process, the composite fiber and / or hollow fiber hardly deforms, and in the elution process, the quality of the hollow fiber is reduced. The phenomenon is minimized. When it is prepared as a fabric, it does not need to go through the weight reduction process in the fabric state, and the prepared fabric has excellent heat retention and light weight. Background technique [0002] Synthetic fibers such as polyester and polyamide are widely used not only in clothing but also in industry due to their excellent physical and ...
