Abstract

The iris fibre is a kind of decorative fibre having structure or laminated alternately overlap structure satisfying isoclinic or isopachous interference condition. It can be made into spinning products and fabrics having iris color. The iris fibre can be produced on the available fibre productive equipment by slightly changing some components such as making special spinneret holes.

Description

Iridescent fibre

This invention is the method for making and the purposes of a series of tencels with rainbow color and iridescent fibre, iris silk, iris tow.

Present fiber, though various structures are arranged, but on fiber, still there is not to produce the optical grating construction of the iris glory effect of grating, the thickness that does not also have stratiform on the fiber to replace each layer in the phase stack structure satisfies the alternately folded mutually structure of stratiform of the thickness of equal inclination interference or equal thickness interference, what do not have also at present that above-mentioned iridescent fibre makes is existing ornamental by force, and the fibre of the pattern with rainbow color or rainbow color of mass producible advantage or the goods of spun articles or fabric or these fabrics are arranged again.

The purpose of this invention is to make optical grating construction or the fiber that the rainbow color is arranged, silk, the tow of the structure that satisfies equal inclination interference or equal thickness interference arranged and make the fibre, spun articles, various fabric, the garment products that have the rainbow color or have the various patterns that are made of the rainbow color by these iridescent fibres, iris silk, iris tow to reach the product of being made by various iris fabrics on fiber.

For this reason, following method for making is selected in suggestion for use.

Method for making one: after spinning machine spinnerets spray silk, make silk or tow be in the plasticity soft state before the drawing-off, on silk or tow, press the tongue and groove of raster-like with molding roller or section mould, after drawing-off, these tongue and grooves just in time become makes visible light be split up into the grating of rainbow color.

Method for making two: the spinneret orifice of spinning machine is made certain section shape, and the silk that spinning machine is sprayed just in time becomes the fiber of the optical grating construction that the rainbow of grating color is arranged after coiling or drawing-off.

Method for making three: adopt the method for making of special-shaped flat filament in the fibrilled film fibre, the special-shaped line of making on film is the asperities of raster-like, the intermediate products or the fiber that just in time become the optical grating construction that the rainbow of grating color is arranged after stretching of film view picture or the flat filament stretching; Or will press the grating tongue and groove after the stretching of film view picture, be cut into silk again or shine fibrillation processing.

Method for making four: on the basis of method for making three, increase the interlayer that reflecting effect is good at the thin layer middle part, for example on certain film, plate one deck and only occupied the aluminum metal reflector layer of the film surface of part, be coated with one deck fibrous material again and seal the aluminium film, the view picture film of this folder aluminium lamination that stretches at a certain temperature, heat treatment makes interlayer adhesion and reflective better again, at last film is carried out the processing of similar fibrillation.

Method for making five: directly with the dense blade roller of similar fibrillation processing this film is cut into netted flat filament with the coloury Jingjing iridescent film of book as far as possible or iris film, must thick slightly tow behind the bunchy.

Method for making six: the method for making that adopts multicomponent flat filament in the fibrilled film fibre, each segment place is subjected to different pulling force when can grooved roll with the tongue roller multi-component film being stretched, and the thickness that makes the fiber of making has the variation that the ripple volt rises and falls and uses on the fiber iris of all kinds is arranged along the elongate fiber direction.Also can cut into adjacent flat filament the flat filament of different in width, the silk of broad is executed big pulling force makes the fiber thickness that is drawn at last identical and the color difference is made various rainbow colors to adjacent fiber, will the tow of iris of all kinds can be arranged also behind their bunchys.The bed thickness of each component should satisfy the condition that equal inclination interference or equal thickness interference or dielectric multi-layer optical thin film are interfered in the above-mentioned fiber.

Method for making seven: adopt fiber to be coated with the skin technology, the fiber that planar structure is particularly arranged at fiber, the different clear coat of refraction index is alternately coated on surface as the fiber of triangular-section, and each coating layer thickness satisfies the condition that equal inclination interference or equal thickness interference or dielectric multi-layer optical thin film are interfered.

Iridescent fibre that is made by above-mentioned method for making or iris silk or iris tow can be by it self or can make the yarn of the iris effect with grating with other fiber, the yarn that yarn, textured yarn, mixed yarn and other method that these yarns can be pure spinning, blended yarn, single strand, the retwist yarns of throwing line, the long monofilament of chemical fibre, the long multifilament of chemical fibre, the compound twisted filament of chemical fibre, textured filament, open-end-spinning, restrain end spins made.

By these iridescent fibres, the iris silk, the iris tow, the iris yarn, can be made into the iris fabric, the fabric that the rainbow patterns that iridescent fibre constitutes is promptly arranged on fabric that all constitutes by iridescent fibre or the fabric, can be made into the goods of iris fabric again by these fabrics, these fabrics or textile article can be cloth, woven, bonded fabric, knitted cloth, knitted underwear, knitted outerwear, knitting socks, knitted gloves, gorros, curtain, door curtain, the cloth of holding court from behind a screen, strap, bunting, the mark fabric, leno, crossover leno, the tablecloth, Canton gauze gambiered, Hangzhoupro sieve, lace, embroidered fabric, embroidery garment, embroidery cloth, coverlet, net, the net fishnet, enlist the services of, mosquito netting, braid, banding, braided fabric, felt, blanket, rope yarn, wallpaper cloth, screen cloth, ornamental tape, the figure painting canvas, fashionable dress, sun umbrella cloth, swimsuit, beachwear, winter dress, sweater, scarf, scarf, cloth bag, faggoting, the homespun of other kind, the woven fabric of other kind, the knitted fabric of other kind, the supatex fabric of other kind, the knotwork of other kind, three-dimensional weave, the fabric of other type.

The method for making of suggestion all is on the basis of existing various fiber method for makings, manufacturing technique and device transformed a little obtain, iridescent fibre and goods thereof can be produced on a large scale, make various fabrics weave or to decorate with a kind of rainbow color of U.S., compared with sheet metal and jewelry or the like decoration on fabric, iris fabric and goods thereof have make big in batches, pattern form is many, rich color is bright-coloured, low cost, available machine washing, decorate careful, wear more comfortable, easy to use, can popularize in the first-class advantage of daily fabric.

Accompanying drawing 1 is the sectional view of the iridescent fibre of certain tool optical grating construction.

Accompanying drawing 2 is shape figure of the spinneret orifice of certain section fiber with optical grating construction.Oblong aperture is main cross sections moulding hole among the figure, and circular hole is surface grating moulding hole.

Accompanying drawing 3 is schematic cross-sections that two or more different refractive index vitreous fibre material stratiform of certain tool replaces the iridescent fibre of folded mutually composite skins bag cored structure.Lines are represented the interface among the figure.

Embodiment: make special-shaped spinneret orifice by accompanying drawing 2, add by method for making 2 that some necessary processing promptly can be made into iridescent fibre in the fiber production.
