Problems solved by technology

For example, China Taiwan Zhongxing Textile developed Coolplus special-shaped cross-section fiber, etc. However, although the above-mentioned special-shaped cross-section fiber with deep grooves has good hygroscopicity, sometimes the absorbed moisture is difficult to be exported in time, resulting in moisture residue or even moisture return. Poor antibacterial properties due to the presence of moisture residue

Embodiment 1

[0030] The preparation method of the special-shaped section fiber of the present embodiment is as follows:

[0031] 1. Preparation of Spinning Melt

[0032] 1.1 Transesterification reaction

[0033] Add dimethyl terephthalate (DMT), ethylene glycol (EG) and zinc acetate into the transesterification tank after metering (the molar ratio of EG to DMT is 2.3, and the addition of zinc acetate is 0.05wt% of DMT ), the temperature is raised to 200°C, and the methanol generated by the transesterification reaction is distilled off through the distillation tower on the top of the transesterification tank. When the distilled amount of methanol reaches 90% of the theoretical amount (theoretically, 1Kg of DMT generates about 0.417L of methanol) the ester is terminated. reaction.

[0034] 1.2 Polycondensation reaction

[0035] Add the reaction product in the polycondensation still, and add the pre-configured diethylene glycol isophthalate-5-sodium sulfonate (the addition is 0.50mol% of D...

Abstract

The invention relates to a modified cross-section fiber and a moisture-absorbing and quick-drying fabric prepared from the modified cross-section fiber, and relates to the technical field of textile fibers. The modified cross-section fiber is a non-circular modified cross-section fiber produced by spinning of a modified polyester chip, the modified cross-section fiber has at least two grooves, theratio of the height (L1) of the grooves to the width (L2) of the grooves is 0.5 or more, and the modified polyester chip is obtained by transesterification and polycondensation reaction of a reactionraw material containing terephthalic acid or polyethylene terephthalate and ethylene glycol. The moisture-absorbing and quick-drying fabric prepared from the modified cross-section fiber has good moisture absorption, moisture guiding and quick-drying effects, has good wearing comfort, no moisture-reducing phenomenon and can maintain a long-lasting antibacterial property.

Description

technical field [0001] The invention relates to the technical field of textile fibers, more specifically, the invention relates to a special-shaped cross-section fiber and a moisture-absorbing and quick-drying fabric made thereof. Background technique [0002] Cotton fiber has the characteristics of hydrophilic groups and good water absorption, and endows cotton fiber textiles with the characteristics of moisture absorption, breathability, softness and warmth. Therefore, people generally like to use cotton fibers as textile raw materials for underwear or sportswear, but cotton fiber textiles Although it has good hygroscopicity, its evaporation rate is low and its moisture permeability is poor. When the human body perspires due to its poor moisture permeability and slow drying speed, it makes the human skin feel uncomfortable such as dampness. With the improvement of people's requirements for the quality of clothing materials, composite fiber textile clothing of cotton fiber ...
