Modification Of Bamboo Pulp Fiber About Antibacterial And Uv-blocking Properties Treated With Cu(â…¡ ) And Zn(â…¡ )

Bamboo pulp fiber is made from cellulose of bamboo in the form of dissolving pulp which is manufactured by chemical manners like alkaline hydrolysis and multistage bleaching, and then turned out via wet spinning. The processing is similar to that of traditional viscose fiber. Generally bamboo pulp fiber has lost the antibacterial property lain inherently in bamboo resulting from the treatment with alkali in the processing and finishing. Besides, the light permanency is bad. So, it is getting an important aspect to endow bamboo pulp fiber with antibacterial and UV-blocking propertiesIt is the objective of this research. Basically Cu(â…¡) and Zn(â…¡) have good antibacterial and UV-blocking properties, bamboo pulp fiber will be combined with them effectively by someway. So the bamboo pulp fiber gets functional with antibacterial and UV-blocking properties.The experiment approach is to treat surface of bamboo pulp fiber with the copper liquor and the zinc liquor, which are prepared in a definite concentration not dissolving cellulose. There are three targets should be gained for the treated bamboo pulp fabrics. Firstly, it has to possess washing fastness in some extent. Secondly, it must be retaining the mechanical property original. Lastly, the antibacterial and UV-blocking properties are achieved according to the design.Bamboo pulp fiber is treated with the copper liquor. The treated one i.e. Cu(â…¡) Complex Bamboo Pulp Fabric is tested by antibacterial, washing fastness and mechanical properties experimentations. Next, structure and properties analysis are performed by SEM, TG, XRD, FTIR and XPS. Finally, The factors dealing with the concentration, reacting time and bath ratios ae used to study the impact to the Cu(â…¡) complex bamboo pulp fiber. The UV-blocking property is tested too.Bamboo pulp fiber is treated with the zinc liquor. The treated one i.e. Bamboo Pulp Fabrics Modified by the zinc liquor is tested by antibacterial, washing fastness and mechanical properties experimentations. Next, structure analysis is performed; finally, the factors are studied, and the UV-blocking property is tested too.The results shows after treatment of [Cu(NH3)4]2+, that Cu(â…¡) is bonded with hydroxyl of cellulose in the fiber forming Cu(â…¡) complex bamboo pulp fabric, which demonstrates excellent antibacterial activity, retains the original mechanical property and possesses washing fastness in some extent. Cu(â…¡) complex bamboo pulp fabric has a good UV-blocking property farther more.The results shows after treatment of [Zn(NH3)4]2+, that ZnO is absorbed onto the surface of the fiber forming bamboo pulp fiber modified by Zn(â…¡), which demonstrates a good antibacterial activity, retains the original mechanical property and possesses washing fastness in some extent. This is a finishing way to be ecological textiles. Bamboo pulp fiber modified by Zn(â…¡) has a good UV-blocking property too.Bath of them implements the three targets above-mentioned.Innovation of this research is represented in the several aspects. Firstly, it is an original ideal and an easy approach, which is inspired by the processing of cuprammonium fiber. Bamboo pulp fiber is treatment with the copper liquor in a definite concentration that can not dissolve cellulose and this is an easy way to do in room temperature. Secondly, not only a good antibacterial but an UV-blocking property is achieved for bamboo pulp fiber after the copper liquor treatment. Thirdly, upon that illumined by the copper liquor, the zinc liquor is prepared to treat bamboo pulp fiber too. This innovates a new and easy way avoiding the dispersion processing of nano-ZnO. Fourthly, as a result of the zinc liquor treatment, bamboo pulp fiber is endowed with good antibacterial and UV-blocking properties.To sum up, it is a good technique to modify bamboo pulp fiber by the treatment of [Cu(NH3)4]2+ and [Zn(NH3)4]2+. At the same time, it is can be referenced by the other cellulose fibers such as cotton. Once more, the process can be put in practice in an easy way. So it has a better perspective for industrialization.
