Problems solved by technology

[0002] At present, the traditional polyester staple fiber products have the following defects: such as poor hand feeling, pilling, poor dyeability under high temperature and high pressure dyeing (difficult dyeing and finishing after blending with animal and plant fibers, complex applicability, not widespread, and large environmental pollution) , and the dyeing color fastness is not high, there is no moisture absorption and quick-drying effect, stuffy feeling when wearing, poor air permeability, low added value and poor wearability, etc.
At present, the moisture-absorbing and sweat-wicking polyester sta

Example Embodiment

[0057] Example 1: This novel functional polyester modified staple fiber with a honeycomb microporous structure has a honeycomb microporous structure. Because the fiber has a honeycomb microporous structure, it has high moisture absorption and quick drying according to the principle of capillary wicking.

[0058] Refer to figure 1 : This method of producing modified polyester chips includes the following steps:

[0059] 1) First, put terephthalic acid, ethylene glycol, dimethyl isophthalate-5-sodium sulfonate and polyethylene glycol ether, ethylene glycol antimony and triphenyl phosphate in the slurry kettle in proportion Fully mixing and slurrying;

[0060] 2) Secondly, the slurry is introduced into the esterification kettle for esterification, and the temperature is controlled at 200°C to 280°C, and the following esterification reaction occurs, and the reaction equation is as follows:

[0061]

[0062] 3) Again, in the polycondensation kettle, polyethylene glycol ether and dime...

Example Embodiment

[0116] Example 2: The difference from Example 1 is that the new functional polyester modified staple fiber with a honeycomb microporous structure contains bamboo charcoal particles of 1.0 μm to 1.2 μm, and the bamboo charcoal particles account for 1.5% to the weight of the fiber. 2.3%. During the preparation, modified polyester chips with a tendency of microporous structure are used, and then a bamboo charcoal masterbatch made of sub-nanometer bamboo charcoal particles is added during the spinning process (the bamboo charcoal masterbatch and the modified polyester with a preliminary microporous structure tendency The chips are melted and spun into the screw extruder together), and finally made into the honeycomb microporous structure bamboo charcoal fiber. The surface and cross-section of the fiber are honeycomb microporous structure. Bamboo charcoal particles are evenly distributed on the surface, surface and inner layer of the fiber, which can give full play to the functions of ...

Abstract

The present invention relates to a new kind of modified functional polyester short fiber in honeycomb microporous structure and its preparation process. The modified functional polyester short fiber has surface and cross section honeycomb microporous structures. The modified functional polyester short fiber has high flexibility, less pilling tendency, high hygroscopicity, normal temperature and normal pressure cation dyeing power and other excellent performance, and is suitable for being blended with other short fibers to maintain the excellent performance.

Description

technical field [0001] The invention relates to the field of spinning, in particular to a novel honeycomb microporous structure functional polyester modified staple fiber and a preparation method thereof. Background technique [0002] At present, the traditional polyester staple fiber products have the following defects: such as poor hand feeling, pilling, poor dyeability under high temperature and high pressure dyeing (difficult dyeing and finishing after blending with animal and plant fibers, complex applicability, not widespread, and large environmental pollution) , and the dyeing color fastness is not high, there is no moisture absorption and quick-drying effect, stuffy feeling when wearing, poor air permeability, low added value and poor wearability. At present, the moisture-absorbing and sweat-wicking polyester staple fibers produced internationally and domestically use ordinary PET chips, which only change the cross-sectional shape (+ font) of the fiber by physical me...
