Description
Technical field
The present invention relates to heat-sensitive variable colour textile field, especially a kind of preparation work of heat discoloration polyester fiber yarn
Skill.
Background technique
Heat-sensitive variable colour textile refers to the textile with thermochromic properties, and heat-sensitive variable colour performance is by heat-sensitive variable colour material
What the variation of material and ambient temperature codetermined, when being heated, the structure of thermosensitive chromotropic material changes, and just will appear color change
The phenomenon that change, conversely, color is restored when temperature reduces again.Thermochromic dye refers to discoloration isomeric types dyestuff in functional dye
One of, having thermochromism, perhaps heat-sensitive variable colour thermochromism refers to that some compounds or mixture exist in temperature
When sounding changes, color can change with the variation of its structure, and this performance is also referred to as " thermochromism " or " heat-sensitive variable colour
Property ", therefore, this thermochromic dye is becoming increasingly popular, but relevant research starting rate of exchange evening, and becomes heat-sensitive variable colour material
Material is for textile dyeing perhaps in stamp finishing technique often due to textile raw material purity is not high enough or finishing technique
It is not good enough, so as to cause the underproof problem of product color fastness index after arrangement, it additionally, there may be colour-changeable yarn product rub resistance
