preparation example Construction

[0048] In the production process of polyester fibers, the present invention also has a feature that the following characteristics are generated by supplying interlacing air when the polyester fibers pass through a pre-interlacer in the weaving process. That is, preferably, since air in one direction within a specific range is supplied to the pre-interleaver, the polyester fiber has a monofilament fineness of 3.7 to 10.5 de, which is equivalent to a fiber having a specific shape. Also, in order to maintain thermal shape stability, preferably, the crystallinity is 40% or more, and more preferably, the crystallinity is 42% to 52%. Also, the polyester fiber has a tensile strength of 6.5 to 8.5 g / d and an elongation at break of 15 to 35%, an intermediate elongation (4.5 g / d) of 6.5 to 17.5% and a shape stability index of 12 to 23 (ES) in order to ensure the required physical properties of industrial fibers.

[0093] Examples 1 to 7

[0094]Solid state polymerized polyester chips with an intrinsic viscosity (IV) of 0.85 g / dL were melted and extruded through a slit spinning capillary.

[0095] Delayed quenching of the extruded molten polyester fibers is carried out by passing through a delayed quenching zone comprising hood heaters and insulating plates.

[0096] Spinning oil is supplied to the quenched polyester fibers by using a roll-shaped lubricating device. At this time, the amount of oil was 0.8 parts by weight per 100 parts by weight of fiber, and ethylene oxide belonging to glycol ester / propylene oxide (30 parts by weight) was used. A spinning oil prepared by mixing the compound (15 parts by weight), triglyceride (10 parts by weight), trimethylpropane triester (10 parts by weight) and a small amount of antistatic agent.

[0097] The oil-provided fibers pass through the pre-interleaver and are drawn by the guide wheels.

[0098] After the drawing process, the drawn fibers...

Abstract

The present invention relates to a polyester fiber with surface smoothness that is maximized by making the cross-section of the filaments flat and uniform, and fabric made of the present fibers is thinner than fabric made of the circular cross-sectional fibers, so it is possible to reduce the amount of coating resin used and to lighten the weight of the product because of low surface irregularityand porosity, and a fabric including the same.

Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS [0002] This application claims Korean Patent Application No. 10-2007-0021632 filed with the Korean Intellectual Property Office on March 5, 2007 and Korean Patent Application No. 10-2007 filed with the Korean Intellectual Property Office on March 9, 2007 - 0023559, which is hereby incorporated by reference for all purposes as if fully set forth herein. technical field [0003] The present invention relates to a polyester fiber and a textile comprising the same. Background technique [0004] Ordinary monofilament fibers have a circular cross-section. Such monofilament fibers with a circular cross-section are generally used in the form of twisted yarns or textiles made from such yarns. [0005] However, in the case of fabrics prepared using fibers of circular cross-section, there is a limitation that, since such fabrics are thick and have high surface roughness and low flatness, the It is not suitable for transfer fabrics of ...
