A kind of sensitization discoloration function shell fabric
Technical field
The present invention relates to a kind of sensitization discoloration function shell fabric, belong to textile technology field.
Background technology
Sensitization discoloration fabric refers to the fabric that color can change under the irradiation of the light source such as sunshine or ultraviolet light, reversiblely again after light disappears becomes original color again.Sensitization discoloration fabric is developed rapidly in recent years, and being people constantly strengthens healthy protect consciousness, more and more higher and to superior, the diversification of textiles, the result day by day strengthened of individual requirement to the Functional Requirement of textiles.The realization of sensitization discoloration fabric relies on 2 kinds of processes usually, one, rely on sensitization discoloration fiber weaving to realize its function, sensitization discoloration fiber weaving is evenly dispersed in by photochromic compound in the chemical fibre spinning liquid such as various terylene, polyamide fibre or polypropylene fibre, relying on solution-polymerized SBR, co-blended spinning or composite spinning technology to produce light to chameleon fibre, forming sensitization discoloration fabric by weaving.This kind of method due to spinning fibre diameter less, therefore in spinning process, particular requirement is had to the size of compound particle diameter, its particle diameter is great Yi barrier fibers comparatively, the too small sensitization discoloration weak effect of particle diameter, in addition, this spinning process requires that photochromic compound has good resistance to elevated temperatures, so be only applicable to chemical fibre, therefore, these requirements have had restriction to the selection of fiber and fabric, hinder its development to a great extent.They are two years old, carry out sensitization discoloration COAT PRINTING Final finishing to fabric exactly to realize, namely be there is by preparation the mill base of sensitization discoloration compound powder, COAT PRINTING is carried out to common fabric, this method is to fiber and fabric non-selectivity, but the sensitization discoloration coating that the method makes easily comes off, and sensitization discoloration effect is poor, and COAT PRINTING technique has certain influence to the comfortableness that fabric is worn.
Summary of the invention
the technical problem solved: for the deficiencies in the prior art, the invention provides a kind of sensitization discoloration function shell fabric, Absorbable rod ultraviolet under illumination condition and produce variable color, reaches variable color sun-proof result, can form again different variable color decorative pattern, this fabric does not have particular requirement to fiber, and sensitization discoloration is effective, fastness is strong, soft comfortable and easy to wear, not only meet the pursuit of people to personalization, certain protection and suggesting effect can be played to people again simultaneously.
