Description
Technical field
The present invention relates to a kind of creeping chill Fypro.
Background technology
As terrestrial climate is gradual warmed up, gradually paid attention to by people with functional fabric.Especially hot humid
In summer, requirement of the human body to environment temperature is reduced to reach it is desirable to wear the clothing of hydroscopic fast-drying of some nice and cool property.In recent years,
As the fabric of summer, have studied using nice and cool sensation is caused when wearing, assign the fibre of the highly cool to touch of refrigerant sense
The fabric of dimension, as the method for the fiber that such highly cool to touch is obtained, implement in the past the water imbibition that improves fiber or
Method of conductivity of heat of fiber etc. is improved, or the hydrophily such as carboxyl or carboxyl Jede resin fibre can be introduced, can also drawn
Enter the fiber containing the resin for being mixed into conductivity of heat filler high or fiber of plating treatment etc. is implemented to surface.However, making
With the occasion of such fiber, although can obtain contact coldness in theory really, but actually enter the function experiment of pedestrian
When, it is no actually to feel contact coldness substantially with common fiber without anything different.
Chinese patent CN102331581A discloses a kind of manufacture method of super cool health-care polyester fiber, the spy of the technique
It is to use inorganic super cool cool feeling master batch to be blended with percentage by weight 8%~15% and polyester slice to levy, through the super nice and cool guarantor of spinning
Strong polyester fiber, wherein inorganic super cool cool feeling master batch is that zinc oxide and far-infrared material are in certain proportion by sheet mica
After mixing, then master batch is obtained with polyester melt blending.However, containing substantial amounts of porous, inorganic powder particle, its result is to feel
Or skin sense of touch produces harmful effect, does not have good comfortableness.
Chinese patent CN201110325475.4 disclose a kind of ice-cold polyester fiber of cross normal atmosphere cation-dyeable and
Its manufacture method, the technique is characterized in carry out melt blending spinning using the ice-cold master batch of mica and normal pressure cation dyeable polyester
Silk, the content of mica powder is 0.8-1.5%, the cross normal atmosphere cation-dyeable for obtaining is sprayed through cross spinneret ice-cold
Polyester fiber.But, although good dyeability has been obtained, but the fiber of reality is no can to feel contact coldness.Simply
The theoretic effect that can obtain contact coldness.
