Embodiment 1

[0038] The moisture-absorbing and fast-drying composite polyester fiber filament of this embodiment is composed of polyester polyester chips modified by copolymerization of ethylene glycol isophthalate-5-sulfonic acid sodium and polyols and conventional polyester polyester chips. filaments formed. Such as figure 1 As shown, the composite polyester fiber filaments include a core layer 1 with a circular cross section and a skin layer 2 wrapping the core layer. The composite polyester fiber filaments have a regular hexagonal star shape in cross section and six grooves. Compared with other The shape structure has better breathable and quick-drying effects; and the cross-section of the composite polyester fiber filament is concentric with the cross-section of the core layer, and the cross-section of the cortex is the part of the regular hexagonal star except the circular core layer.

[0039] The cortex comprises conventional polyester polyester slice A and ethylene glycol isophtha...

Embodiment 2

[0042] This embodiment is the processing technology of the hygroscopic and quick-drying composite polyester fiber filament of embodiment 1, comprising the following steps:

[0043] 1) The processing steps of slice B: Polyterephthalic acid PTA (45 parts), ethylene glycol EG (28 parts), polyisophthalic acid PIA (10 parts), sodium benzenesulfonate (5 parts), poly Mix ethylene glycol PEG (2 parts), react at 200-250°C for 3-5 hours under normal pressure; then add quaternary ammonium salt (0.5 part), antioxidant 1010 (0.6 part), triphenyl phosphite Ester (0.5 parts), heated up to 250-280°C, pumped under low vacuum for 1 hour, and then under 0.1KPA vacuum condition for 1-2 hours, prepared ethylene glycol isophthalate-5-sodium sulfonate modified polystyrene Ester polyester chips B.

[0044] 2) Slice A and slice B are crystallized at 70-80°C, and then dried at 110-130°C. After drying, the cortex material and core layer material are mixed: the cortex material is slice A (35 parts) and ...

Embodiment 3

[0046] The difference between the hygroscopic and quick-drying composite polyester fiber filament of this embodiment and that of Embodiment 1 is that the cortex of this embodiment includes conventional polyester polyester chip A and ethylene glycol isophthalate-5-sodium sulfonate modification. Permanent polyester polyester chip B, wherein, by weight: chip A is 48 parts, and chip B is 10 parts; The core layer is conventional polyester polyester chip A, and the weight part is 50 parts.

[0047] Ethylene glycol isophthalate-5-sulfonate modified polyester polyester chips B, comprising the following components by weight: 48 parts of polyethylene terephthalic acid PTA, 30 parts of ethylene glycol EG, polyisophthalic acid 11 parts of PIA diformic acid, 5.5 parts of sodium benzenesulfonate, 2.5 parts of polyethylene glycol PEG, 0.7 parts of quaternary ammonium salt, 0.8 parts of antioxidant 1076, and 0.6 parts of triphenyl phosphite; Technical characteristics refer to embodiment 1.

Abstract

The invention belongs to the technical field of chemical fibers, in particular to a moisture-absorbing rapid-drying composite polyester fiber filament. The composite polyester fiber filament comprises a core layer and an outer layer for coating the core layer, wherein the core layer is prepared from a polyester dacron slice A; the outer layer is prepared from the polyester dacron slice A and a modified polyester dacron slice B. The invention further discloses a process of machining the moisture-absorbing rapid-drying composite polyester fiber filament. The machining process comprises the following steps: (1) drying the polyester dacron slice A and the modified polyester dacron slice B; (2) physical preparation: a component I is taken as the materials of the outer layer, and is prepared by co-blending the polyester dacron slice A and the polyester dacron slice B according to the proportion; a component II is taken as the material of the core layer, and is prepared from the polyester dacron slice A; (3) feeding the component I and the component II into a screw rod for extruding to obtain the composite polyester fiber filament with the outer layer and the core layer. The prepared composite polyester fiber filament has high moisture-absorbing and rapid-drying performance.

Description

technical field [0001] The invention belongs to the technical field of chemical fibers, and in particular relates to a moisture-absorbing and quick-drying composite polyester fiber filament and a processing technology thereof. Background technique [0002] Generally, polyester polyester fiber filaments are filaments with circular cross-sections. The fabrics woven are crisp, shape-retaining, good in resilience, washable and wearable, and easy to care for, and are very popular among consumers. However, since polyester is a water-repellent fiber, its poor moisture absorption and air permeability affect the comfort of wearing, and also affect the high-quality consumption of polyester fibers. With the continuous development of technology, from hydrophilic additives to fiber structure changes and material changes, a lot of research has been done to improve the wearing comfort of polyester polyester fibers. [0003] For example, the Chinese invention patent application with the ap...
