The present invention relates to a kind of cameleon fibre, variable color fiber dyed yarn and fabric and working method thereof, produce according to following step, cotton fibre is carried out pre-treatment, carry out cation-modified process afterwards, improve the cationic of cotton fibre, the thermochromic dye of microcapsule structure is adopted to dye again, finally by fixation and oven dry, obtain temperature and become variable color cotton fibre, then adopt the spinning process of colour-spun yarns to carry out spinning and obtain variable color fiber dyed yarn, and adopt that variable color fiber dyed yarn carries out face weave, the rear operation such as whole obtains variable color look textile fabric. It is strong that product of the present invention not only has the dim sense of colour-spun yarns, stereoscopic sensation, the feature that color is implicit, natural, have levels, and there is the style that colour-changeable yarn color is changeable, randomness is strong, the present invention simultaneously adopts fiber to carry out modification, dyeing, a large amount of water resourcess can be saved, being combined by ionic linkage between dyestuff and fiber, washing fastness and color fastness are all fine, are fiber dyed yarn and the fabric of a kind of brand-new style.

Description

A kind of cameleon fibre, variable color fiber dyed yarn and fabric and working method thereof
Technical field
The present invention relates to textile technology field, for the cameleon fibre of a kind of novel style, variable color fiber dyed yarn or fabric, specifically fiber is processed by a kind of employing microcapsule Thermo-color Dyes, then carry out spinning and face weave, obtain a kind of cameleon fibre, variable color fiber dyed yarn and the variable color look textile fabric that can vary with temperature and occur color to change.
Background technology
Fiber dyed yarn is generally with the fibre spinning resultant yarn of two kinds and two or more different color and lusters or different performance, due to the difference of various filament contraction or colouring property, during arrangement after yarn is made into cloth is processed, the style that cloth cover presents multicolour, feel is soft, surface sense is plentiful can be made, it is to increase value-added content of product. Conventional short-staple all adopts dyeing keratin-fiber to obtain coloured fibre then to carry out spinning into fiber dyed yarn, and chemical fibre adopts original liquid coloring technology to add Masterbatch in spinning solution to carry out melt-spinning fibroblast and then carry out look spinning processing substantially. Colour-spun yarns has that low cost and high added value, range of product variability be strong and multinomial advantage and the feature such as production process energy-conserving and environment-protective, changes traditional technology, it is achieved that without discharge dyeing, solves the problem that dyeing is polluted from source.
Reversible temperature-sensitive chromotropic dye is a kind of microcapsule repeatedly changing color with rise in temperature or decline, it has the organic compound objects system preparation of special chemical structure by a class, its molecule is relatively big, water-soluble poor, and dyestuff itself does not have and the functional group that cotton fibre macromole is combined. Within specified temperatures because transfer transport makes the molecular structure of this organism change, thus realize the transformation of color. Not only color is bright-coloured for this kind of Thermo-color Dyes, and repeatedly can realize the change from coloured to colourless or from colourless to coloured. Microcapsule have 0.2��0.5 micron and neither dissolve also nonfused transparent outer cover, and heat discoloration body is coated on inside by it, protect them not by the erosion of other chemical substance extraneous such that it is able to repeatedly reversible use.
Chromotropic dye is applied on fabric, mainly adopt coating interpolation tackiness agent to carry out high temperature to bake, or adopt pigment printing and coating to realize, but generally there is the defect of colour fastness difference, Boardy Feeling, poor durability, if it is unworkable for adopting conventional chromotropic dye dyeing to carry out cotton fiber dyeing, major cause has:
1, cotton fibre dyes when fluffy, if interpolation tackiness agent carries out set can make to produce between cotton fibre serious adhesion, it is very difficult to separately, also just cannot carry out the spinning processing in rear road;
2, need to carry out the washing processing in many roads after being made into fabric due to colour-spun yarns, the fastness of conventional chromotropic dye dyeing can not carry out the washing of many roads, otherwise it is serious to fade, and cannot use.
The patent No. be ZL200710032110.6 patent in also mention and adopt cation-modified liquid process cotton fabric, then adopt natural dyestuff to dye, it is to increase the dye uptake of cotton fabric, color depth and dyeing uniformity. ZL201010195278.0 also mentions and adopts cation modifier process bombax cotton, then adopt anionic dyestuff to dye, it is to increase dye uptake and shortening dyeing time, reduce the interpolation of dyeing accelerant.
But their method of modifying cannot use in microcapsule chromotropic dye, mainly there is following problem:
1, the anionic property of microcapsule is very weak, it is the shell of a kind of ball, inside is coated with heat discoloration body, the anionic property of itself is very weak, it is different from the anionic property of anionic dyestuff and natural dyestuff, if so only wishing to be combined with dyestuff by modified cation group, then dye uptake and every fastness do not reach requirement certainly, cannot use;
2, the consumption of properties-correcting agent and caustic soda is very big, properties-correcting agent is more than 10g/L, processing cost is very high, being difficult in actual production adopt, and the color of natural dyestuff is very dim, kind is also little, look flower when the uneven meeting of modification causes dyestuff to be painted, market does not have the product of Pure natural dye occur, also not to marketing, very immature.
The staining technique of chromotropic dye is applied in fiber treatment by the present invention, play the advantage of color-change technology in colour-spun yarns field and feature, change and promote the style and characteristic of colour-spun yarns, invent a kind of varying with temperature and the warm of variable color becomes the feature that fiber dyed yarn is the present invention.
Summary of the invention
The present invention provide a kind of have vary with temperature and novel cameleon fibre, variable color fiber dyed yarn and fabric that color and style change.
The present invention adopts high performance cation modifier process cotton fabric, providing cotton fabric strong cation, consumption is few, efficiency height, fully can be combined with microcapsule and form ionic linkage, adopt reactive fixing agent coating dye to be formed on the surface of fabric more firmly to combine, it is to increase every colour fastness of dyestuff and washing performance simultaneously, thus meet the service requirements of process for processing and human consumer.
Product of the present invention also realizes, by the mutual collocation of different transition interval dyestuff, a kind of mannerism presenting multiple different colours effect at different temperatures. Product of the present invention realizes mainly through techniques such as pre-treatment, cation-modified, Thermo-color Dyes specific stain, special fixation.
