| Abstract: | Conclusions. Based on the results of the experiment, the following can be concluded. ˙ A thin adhesive application will always be more useful than a thicker one. ˙ Carboxy methyl cellulose and methyl cellulose can be used for lamination even in a concentration of 1%. ˙ Maida paste and dextrine in low concentrations do not have enough sticking ability, but mixing each with CMC or MC in 1:2 proportion results in a quality acceptable for application to supporting materials. ˙ As regards the supporting materials, all are useful, which means that they can be chosen according to the state of the object. If the document is very fragile and weak, a support of handmade paper or chiffon may be required. If, as in the case of laminating valuable records or documents, the application of a thick supporting material will result in reduced transparency, then tissue paper should be applied on the written face and a strong paper or chiffon should be applied on the unwritten reverse side of the object. ˙ Chiffon cloth in a yellowish or off-white colour is more useful than a white colour as support in documents. Further studies will be undertaken in order to find out whether the Indian tissue paper procured from KVIC (Khadi and Village Industries Commission, Dehra-dun, India) can be a useful substitute for Japanese tissue paper. Summaries. A study of adhesives and supporting materials was carried out in order to develop methods of lamination for very old and weakened documents of paper and allied materials. This paper reports the use of simple and easily accessible materials and, on the basis of the study results, recommends adhesives and supporting materials that can be used effectively and successfully for the lamination. |
