Method for making cool colored special-shaped super fine denier polyester filaments

Abstract

The invention relates to a method for making cool colored special-shaped super fine denier polyester filaments. The method comprises the steps of (1) making cool colored master batches, and (2) making cool colored special-shaped super fine denier fibers. In the step of making the cool colored special-shaped super fine denier fibers, firstly, extrusion mixing and fusing are conducted on 1-20 parts of cool colored master batches and 80-90 parts of polyester chips through a screw machine to obtain a melt, and spinning is conducted through a spinneret plate; secondly, cross air blasting is conducted on slivers obtained through spinning so that spun filament fibers can be obtained through cooling and solidification; thirdly, oil is applied to the solidified spun filament fibers, wherein the weight concentration of an oiling agent is 10-18%, and the rotating speed of an oiler is 4-6 rpm; fourthly, spun filaments are taken-up through a coiler under the temperature of 24-28 DEG C and the relative humidity of 45-65% after being oiled, and then the cool colored special-shaped super fine denier fibers are obtained. According to the method, the cooling function of a cool auxiliary, the wicking effect of the super fine denier fibers and the sweat releasing function of special-shaped fibers are combined, in other words, three physical modification methods are combined, and the obtained fibers have a dry fit function and feel cool and comfortable.

Description

【Technical field】 [0001] The invention relates to the technical field of polyester filaments, in particular to a method for preparing cool-feeling colored special-shaped superfine denier polyester filaments. 【Background technique】 [0002] Polyester has the characteristics of comfortable and crisp, high strength, impact resistance, good elasticity and elastic recovery, elastic modulus, good wear resistance, good light resistance, and corrosion resistance, but polyester has poor hygroscopicity, and it feels stuffy when worn. Static electricity, stained with dust, affect the appearance and comfort, and the development of cool fiber can meet the requirements of consumers for the coolness and comfort of summer clothing. [0003] At present, there are several general realization methods of contact cool polyester fabrics on the market: [0004] One is to mix and spin a substance with a cooling effect with polyester chips to form a filament with a cooling effect, such as jade fibe...

AI Technical Summary

Problems solved by technology

[0008] Cool feeling colored special-shaped ultra-fine denier fibers need to add cooling additives, which will cause certain difficulties in the spinning and forming of fibers, especially for spinning colored special-shaped ultra-fine denier polyester fibers. The production process is extremely complicated and needs to be added Colored masterbatches and cooling additives must be prepared at the same time with extremely low denier, so the adjustment of process parameters seriously affects the quality of filaments

[0009] Chinese Patent Publication No. CN102031581A discloses a kind of flake mica, aluminum oxide, zinc oxide three kinds of powders mixed to make inorganic nanometer super cool polyester masterbatch, and prepared into super cool cool health polyester fiber, but At present, there is no patent report of cool-feeling colored special-shaped ultra-fine large polyester filament
