Description

Double combined elastic fibrous composites and elastic multifilament fiber

Technical field

The utility model is a kind of related fibrous composite, and it is fine to constitute inner core especially with thermoplastic elastomer (s) Dimension, and sheath outer layer is constituted using thermoplastic material, and tool elasticity is formed by the surface of sheath outer layer coating to interior core fibre Double combined elastic fibrous composites and elastic multifilament fiber comprising the composite material.

Background technique

In recent years, as outdoor activity general mood is prevailing, functional movement fabric sales volume is consequently increased, meanwhile, generally disappear Take requirement of the user to fabric functional to be also stepped up.For example, in addition to will other than slimmer and more graceful, moisture absorbing and sweat releasing, antibacterial deodourizing, The elastic fiber fabric that it is further desirable to tool snug fit sense can reduce constraint sense.Therefore, on material technology, extend with More mobile possibilities are needed between restoring force, and optimum balance can be obtained between functional and comfort.

Since elasticity spins fine technology in the case where improving fabrication steps year by year, has and be more easily manufactured, process, is durable, producing The fast and low in cost advantage of efficiency, and it is widely used in many functional movement fabrics.

But in the prior art, general elastic fiber fabric has the disadvantage that needs overcome.

Firstly, being not suitable for having sternly latex for elastic fiber fabric made by elastodiene fibre (elastic silk) The user of the allergic symptom of weight.It is usually replaced with synthetic rubber such as neoprene, butyl rubbers, to avoid allergy is caused Reaction.However, the cost of synthetic rubber is usually relatively high, thus the competitiveness of made elastic fiber fabric more weak tendency.

In addition, the relatively broad material for being used to be made elastic fiber fabric also include polyurethane fiber (Spandex, OP, spandex, elastic yarn).Only, polyurethane fiber has several problems: first, the problem for having recycling difficult；Second, the meeting in burning Dioxin is generated, environment is seriously polluted；Third, weatherability, light resistance are bad, influence using life time.

Furthermore polyester ether elastic fiber (TPEE) is also the material of common elastic fiber fabric.Only, polyetherester elastomer is fine The fiber stiffness of dimension is harder, influences the pliability of elastic fiber fabric, and simultaneous processing condition is also relatively narrow, it is necessary to which use is more accurate Processing machine, lead to that prices are rather stiff.

It directly reels off raw silk from cocoons also, every elastomer adopts one-component elastomer, leads to more elastomers of elastic fiber fabric Between have the problem of mutual adhesion.

Especially, requirement of the fabric in dyeing, sizing (hot dimensional stability, smoothing wrinkle) to temperature is very high.Further lift For example, polyurethane fiber (Spandex, OP, spandex), the elastomer of polyester (Polyester), polyamide (Nylon), When collocation thermal finalization, it is necessary to bear 180~240 DEG C of high temperature.More and, the heat setting temperature of this kind of polyurethane elastomeric fiber exists 180 DEG C or more, 160 DEG C of fusing point than polypropylene (Polypropylene, PP) fiber are taller, and polypropylene fibre is caused to coat This kind of polyurethane elastomeric fiber and after forming yarn, can be because of glass transition point (glass between material different from each other Transition, Tg) difference and the effect of making thermal finalization be affected.It is well known that temperature is too low, elastomer Fabric just can not smoothing wrinkle, stable size；But when the temperature is excessively high, polypropylene fibre will become flowable state, lose its fiber kenel So that not being available.

Existing polypropylene fibre is that color grain is added and becomes coloured fiber when manufacturing fiber.But Be dyeing and finishing after thus will cause the more traditional woven fabric of color diversity engineering method it is also poor.

For example, the dyeing temperature about 110 of about 130~135 DEG C of the dyeing temperature of polyester fiber, resistance to grand fiber (Nylon66) DEG C, and about 125 DEG C of the dyeing temperature of OP elastomeric yarn, it is all quite high.(polymerization yarn) although have stainability in particular, OP elastomeric yarn, But do not paint, also that is, dyestuff is only attached on surface, so whole dyeing strong degree is very poor.
