Research Of Skin-care Cellulose Fiber Containing Vitamin E

Functional aspects for clothing textiles,which promote the wearing comfort and well-being have become a striking sales argument.Skin-care textile containing vitamin is one of the functional textiles.Cellulose fiber containning vitamin E was prepared in this paper.In order to get cellulose fiber containning vitamin E,preparation of the micro-capsule of vitamin E,the inclusion compound of vitamin E andβ-cyclodextrin, and cellulose solution was investigated,then the fiber was wet-spun by mixing the compound in the cellulose solution.The complex of vitamin E andβ-cyclodextrin was prepared,and the prepared inclusion compound was analysed by using UV,FTIR,XRD,TG etc.It is found that the inclusion ratio of vitamin E andβ-cyclodextrin is 1:1.The stability of the complex to the UV light and heat is excellent.And the complex of vitamin E andβ-cyclodextrin possesses desirable slow release property,which is best in 35-40℃.To get desirable cellulose spinning solution,dissolution of cellulose in NaOH/Urea/Thiourea aqueous solution and ionic liquids(AMIMC1 and BMIMC1) was researched in this paper.7wt%NaOH/9wt%Urea/9wt%Thiourea aqueous solution and AMIMC1 were found have the greatest power to dissolve cellulose.Throgh investigating the dissolution condition and properties of the regenerated cellulose, 7wt%NaOH/9wt%Urea/9wt%Thiourea aqueous solution,the preferable solvent,is chose for preparing the spinning solution.Cellulose spinning solution containing the vitamin E/β-cyclodextrin complex was prepared by mixing the complex in the cellulose solution.Rheological property of cellulose solution and that containing the vitamin E/β-cyclodextrin complex was tested by the falling sphere vis-cometer and capillary rheometer.Cellulose with(?)=650 was found be best for preparing the spinning solution,and 5%was the optimal concentration of spinning solution.The flow behavior of the spinning solution was not changed by blending of the complex in cellulose solution,whose non-newtonian index decreased as the content of the added complex increased.Based on the study of rheological property of the cellulose solution,the cellulose fiber and the skin-care fiber containing vitamin E was made by wetting spinning method.The coagulant composition and condition was researched.It was found that fiber spun from two-step coagulation was better than one step coagulant,and the composition of the two coagulant was 10wt%H₂SO₄/10wt%Na₂SO₄ aqueous solutioin and 5wt%H₂SO₄ aqueous solution respectively,and the best coagulating temperature was 20℃.And the most appropriate content of the comlex is 10%.The stength of cellulose fiber and that containning vitamin E spun with the best spinning technique was 2.22cN/dtex and 2.28 cN/dtex.Round cross-section,smooth surface and even distribution was observed in the SEM photograph of the prepared fiber.
