Abstract
The invention discloses a novel polyester composite elastic fiber with the heat insulation function. The fiber is in a double-ingredient parallel composite structure, the section of the fiber is round, and the interior is in a hollow structure. The two ingredients of the parallel composite fiber are selected from PET, PBT, PTT and CO-PET and are different; far infrared powder is added in at least one ingredient. The naturally-cured spiral structure of the fiber is formed through the different contraction rate of two different polyester ingredients, and the permanent elasticity is provided; since the internal hollow structure and the far infrared powder are adopted, the elastic fiber has excellent heat insulation effect; the fiber is widely applied to high-grade underwear, sportswear and warm clothing and has the advantages of elasticity, comfort, lightness, heat insulation, skin-friendly performance and air permeability.
Description
Technical field
The invention belongs to Multifunction field of polyester fiber, particularly relate to a kind of have concurrently warming and hollow far infrared, double component polyester composite elastic fiber of permanent elasticity.
Background technology
Weaving elastomer develops from rubber elastomer, and towards the future development of variation, functionalization, the design for weaving face fabric provides more selection.At present, elastomer is mainly derived from spandex, polyamide fibre and polyester complex fiber etc., and spandex and polyamide fibre all have good elasticity, but its resilient durability and comfortable skin-friendly poor, spandex non-refractory, polyamide fibre easily plays fold etc. in dress.And the natural coiled structure of polyester complex fiber can produce permanent elasticity, and elasticity is comfortable, chainless sense, and dimensional stability for fabric is good, in the application of underwear and sportswear, embody outstanding advantage.
The Comfortable elastic of polyester composite elastic fiber and durability, make its applicability wider, can develop more diversified elastic textiles.But at present the research of this fibrid is still rested on to the stage of simple function, blank state is faced to its polyfunctional exploitation.The present invention is directed to the deficiencies in the prior art, develop and have warmth retention property and flexible Mobyneb polyester composite elastic fiber concurrently.
Summary of the invention
The object of the present invention is to provide a kind of brand-new polyester composite elastic fiber, on the excellent resilience basis possessing existing product, have the warming effect of hollow far IR fibre concurrently, and it is more more frivolous than common composite elastic fiber fluffy, comfortable skin-friendly is better, in long filament or short fiber application, all embody outstanding multifunctionality.
For achieving the above object, the preferred technical scheme of the present invention is as follows:
Warming-type polyester composite elastic fiber, its architectural feature is: fiber is that two component parallel is compound, hollow structure inside.Two kinds of components of parallel composite fiber are respectively taken from the one in PET, PBT, PTT and CO-PET, and different; Have at least in a kind of component and add far infrared powder.
Fiber cross-section structures is annular, is made up of two kinds of component compounds arranged side by side, and wherein two kinds of constituent mass ratios are 3: 7 ~ 7: 3.
The two kinds of polyester components forming composite fibre have one at least for hydrophilic modifying polyester, and surface is containing hydrophilic radical.
Add far infrared powder at least one component of composite fibre, powder adds with polyester master particle form, and addition is 2% ~ 4% of fiber.
Warming-type polyester composite elastic fiber of the present invention, comprises long filament and staple fibre.
For achieving the above object, the preparation technology of this fiber is as follows:
The spinneret component melt spinning of side. by-side conjugation spinning technique and special construction is adopted to obtain: by two kinds of polyester raw material chip dryings, far infrared powder master batch adds in one or both polyester components and mixes, two kinds of components are input in two screw extruders of composite spinning equipment respectively, spinning manifold is inputted after measuring pump measures respectively, spinneret component through special construction melt extrudes, quenching, oil integrated tow, obtains long filament or the short fiber of warming-type polyester composite elastic fiber through tow post processing and heat setting process.
The fiber number of above-mentioned elastomer is 2 ~ 200dtex, curling extensibility more than 35%, Curl response rate more than 70%, warming rate more than 30%, excellent combination property.
Beneficial effect of the present invention:
Contrast existing polyester composite elastic fiber, fiber of the present invention has the following advantages:
1) composite fibre improvement is hollow structure, has good heat-insulation warm keeping, and higher degree of hollowness, make elastomer entirety more frivolous fluffy, compressibility is good, and very pro-skin is soft, meets light, thin, the warm pursuit of people to clothes.
2) also add far infrared composition in fiber, produce good accumulation of heat effect, play excellent effect of keeping warm with the hollow structure acting in conjunction of fiber.
3) the hydrophilic modifying polyester components in fiber provides a large amount of hydrophilic radical, and make composite fibre have from hydrophily, obviously improve the hydrophobic property of conventional polyester class elastomer, fabric arranges without the need to hydrophilic additive, namely has good sucting wet air permeability.
The present invention has the elastomer of heat-preserving function concurrently, more comfortable than the elasticity of spandex durable, and chainless sense is high temperature resistant, good stability of the dimension; More frivolous than general polyester composite elastic fiber, ventilative, and increase effect of keeping warm, realize the composite multifunction of elastomer.
