Problems solved by technology

Chinese patent CN102660018A and Chinese patent CN202968797U both announced the application of this material in fibers to improve the heat resistance or barrier properties of fibers, but did not involve its blending with PET to prepare colored special-shaped fibers
Chinese patent CN1211204C discloses a production method of PET / PEN blended or copolymerized film, but does not involve the preparation of fibers
Chinese patents, but none of them involve the effect of barium sulfate on the properties of PET / PEN fibers
Although there are a large number of reports on fiber specialization, there is no report on monofilament specialization.

Abstract

The invention relates to a colored special-shaped size-stabilized type polyester monofilament and a preparation method thereof. The colored special-shaped size-stabilized type polyester monofilament is composed of, by weight, 84.5 parts to 99.75 parts of polyethylene terephthalate (PET), 0.2 part to 5 parts of color master batches, 0.1 part to 10 parts of poly(ethylene 2,6-naphthalate) (PEN) and 0.05 part to 1 part of barium sulfate powder. By adding the PEN, the thermal resistance of fiber is improved, and no roller sticking phenomenon can occur even when the heat setting temperature is above 245 DEG C; nanometer barium sulfate plays a role of plasticizer, the slippage among high polymers is improved, the drawing ratio is increased, the fiber contraction rate is decreased, and meanwhile the colored fiber can be more uniform and brighter in color and luster; the high drawing ratio is achieved in the fiber drawing process, induced crystallization produced in the fiber drawing process is improved, and the boiling water shrinkage is decreased; the fiber preparing process is simple, dry strands are uniform, fiber is uniform in thickness, woven fabric is smooth, grids are exquisite and uniform, and a colored special-shaped filament is softer and richer in color so that stylized reflection can be facilitated.

Description

【Technical field】 [0001] The invention relates to the field of fiber technology, in particular to a colored special-shaped dimensionally stable polyester monofilament and a preparation method thereof. 【Background technique】 [0002] Low-shrinkage polyester industrial yarn has been widely used in the field of narrow fabrics such as filter cloth, sunshade cloth, tarpaulin and so on. Fabrics woven from traditional low-shrinkage polyester industrial yarns have a large shrinkage rate and uneven shrinkage after coating heat treatment, which can easily cause uneven fabric surfaces, so they can only be used for weaving narrow-width fabrics. In recent years, due to the rapid development of materials such as membrane structures, higher requirements have been put forward for the dimensional stability of fabrics, while ordinary low-shrinkage polyester industrial yarns cannot meet the requirements of wide fabrics with a width of more than 5 meters; etc. have put forward higher requireme...
