Abstract
The utility model relates to a moisture-absorbing and sweat-releasing antibacterial elastic fiber. Fiber tows consist of two monofilament units with different finenesses and structures; the monofilament units consist of fewer thick monofilament units on the inner side and more fine monofilament units on the outer side, wherein the sections of the thick monofilament units adopt parallel or eccentric core sheath type composite structures; the sections of the fine monofilament units adopt structures with such abnormal shapes as three-leaf shapes, cross shapes, I shapes and inversed-E shapes. The thick monofilament units are positioned in the centers of the tow structures, and are tightly arranged; the fine monofilament units are arranged on the outer side in a multilayer concentric circle manner. The fiber tows are compounded by two polyester or copolyester components, and a silver ion antibacterial agent is added in at least one component. The fibers give excellent hand feeling, free elasticity, moisture-absorbing and fast dry comfort and a compatible antibacterial effect to the textile fabrics.
Description
Technical field
The utility model belongs to tencel field, relates in particular to a kind of polyester composite elastic fiber with moisture absorbing and sweat releasing and antibacterial functions.
Background technology
At present, spandex is widely used in producing with weaving, knit product and the medical elastoplast of spring function.Due to the production technology relative complex of spandex, processing cost is high and environmental requirement is strict compared with molten spinning fiber, therefore, chemical fibre circle is devoted to research and develop polyesters elastomer for many years to substituting the spandex involving great expense, and wherein the company such as U.S.'s English Weida, German Bayer and Japanese Asahikasei makes substantial progress.
In recent years, high elasticity polyester fiber has successively experienced the developing stage such as traditional stretcher strain, asymmetric cooling strain, new polyester exploitation and two component be compound, and wherein the spinning elastomer that is developed as of double component polyester composite fibre opens up a new way.The product variety made by this method is many, added value is high, is one of desirable feedstock of high-grade fabric.But with regard at present domestic exploitation situation, polyester composite elastic fiber still has the room for promotion of very large quality and performance, comprises the improvement of elasticity comfort level, feel and the gas permeability of fiber itself, and the Application and Development of composite multifunction etc.
Summary of the invention
The polyester composite elastic fiber that provides a kind of structure special is provided the purpose of this utility model, has good hand touch, elasticity is free and relaxed, the multifunctionality of moisture absorbing and sweat releasing and antibiotic health care.Solve ordinary elasticity fiber feel stiff, elasticity is not durable, and elastic force is tight, the poor sultry discomfort causing of gas permeability.
The utility model adopts following technical scheme:
A kind of anti-microbial elastomeric fiber of moisture absorbing and sweat releasing, its architectural feature is: fibre bundle is arranged and formed by two kinds of fiber number monofilament unit different with structure, it is respectively thick type monofilament unit and outside a fairly large number of thin type monofilament unit of inner side negligible amounts, wherein cross section, thick type monofilament unit is arranged side by side or eccentric core-sheath-type composite construction, and cross section, thin type monofilament unit is abnormity as three leaves, cross, I-shaped and epsilon-type structure.
The filament number of thick type monofilament unit, inner side is 1.5～10D, and quantity is 1～20, is positioned at the center close-packed arrays of tow structure; The filament number of thin type monofilament unit, outside is 0.2～1.5D, and quantity is 10～1000, is positioned at tow structure outside and arranges with multilayer concentric round type.
Different polyester or the copolyesters of two specific character viscosity that the component that forms fiber is, wherein low sticky component is the one in polyester (PET), cation dyeable copolyester (CDP), low temperature cation easily dying copolyester (ECDP); High sticky component is polytrimethylene terephthalate (PTT), or polybutylene terephthalate (PBT) (PBT).
In fibre bundle, heavy denier yarn weight accounts for 5%～60%, and fine denier filament weight accounts for 40%～95%; In two component heavy denier yarns, low sticky component accounts for 30%～70%, and high sticky component accounts for 70%～30%.
Antiseptic is the antibacterial polyester masterbatches containing nano-silver ionic, and antiseptic is added in low sticky component, alternative interpolation in high sticky component.
The beneficial effects of the utility model:
Improve feel and elasticity comfort level: the compound heavy denier yarn of polyester in fibre bundle provides permanent elasticity, outer coated profiled fine denier fiber is given pliability, and reaches moisture absorbing and sweat releasing effect; Heavy denier yarn has determined the elastic characteristic of fiber, and itself does not have elastic force fine denier filament, does not affect the elastic telescopic scope of fiber, but can suitably reduce the tensile strength of fabric integer, solve the tight sense problem that general thick dawn elastomer easily has, reach elasticity abundance, but elastic force object easily.
Moisture absorbing and sweat releasing and antibiotic multifunction: conventional polyester class elastomer, fiber Contact is tight, adds that the hydrophobicity of polyester itself causes gas permeability poor, and the damp and hot microenvironment of generation not only affects the easier breed bacteria of wearing comfort, even if interpolation antimicrobial component, is difficult to the effect that reaches desirable.In the utility model fiber, mix a large amount of shaped filaments, form micro-groove of wetness guiding perspiration discharging, ventilative dry and comfortable microenvironment is unfavorable for bacteria live simultaneously, and pulp freeness increase makes inner antiseptic bring into play better effect.

The specific embodiment
Below in conjunction with embodiment, the utility model is described in further detail:
Embodiment
Fiber is by low sticky ECDP and high sticky two kinds of polyester components of PTT are compound forms, and in ECDP component, adds silver ion antimicrobial agent.Wherein the compound heavy denier yarn of ECDP/PTT is positioned at tow inner side, and outside is coated ECDP fine denier filament; The compound heavy denier yarn of ECDP/PTT is parallel type structure, and ECDP fine denier filament is cross section trilobal.
In fibre bundle, comprise 5 of compound heavy denier yarns of ECDP/PTT (ECDP/PTT=50/50), be positioned at fibrillar center position close-packed arrays, filament number is 10D; 250 of ECDP fine denier filaments, are coated on the 3 layers of circular distribution in outside, and filament number is 0.8D.Fiber total fiber number 250D, wherein heavy denier yarn/fine denier filament=20/80, antiseptic addition 0.5%.
