Abstract
With respect to the cultural and creative forest products, the proposal plans to execute along two main axes, i.e., enhancement of woodwork craftsmanship and DIY products R&D, and research on handmade paper traditional art items. Research and develop of wooden technological upgrading and DIY products The purpose of this plan was to establish wooden woodwork classroom to Wooden as R &D base. The establishment of the maintenance of old furniture timber doctor. Workers DIY wood-base material products education center, production and development of timber commentary specimen trees and DIY products. Establish Wooden platform, for environmental education activities with volunteer work to develop innovative Wooden products. Research on handmade paper traditional art items With respect to research on handmade paper traditional art items, four agendawill be carried out, i.e., (1) the new and old papermaking technologies; (2) specialty functional papers; (3) R&D on novel nondestructive inspection and detection method for pulping; and (4) cultural and creative products development made of handmade paper.1. Establishment of scientific database for standardization of restoring paper-based cultural relicsPaper-based cultural relics are important cultural assets of mankind. However, because the carbohydrate nature of the medium, they are liable to be affect“ed by various factors, such as light, humidity, temperature factors or irresistible external forces and become aged or damaged. Regardless of natural disasters, human errors, or natural aging, after cultural items are mounted for a period of time, as short as several years or as long as a century, they would require restoration and remounting. However, procedures for restoring often depend on the conditions of individual works or experience of the restorers. These resulted in inconsistent practices and end results. For experienced restorers, old cultural relics can often return to their former glory. However, for the less experienced practicians, it may mean the end of life for an artwork which is a great pity. This study proposes to collect the practical procedures and methods of domestic and foreign restoration organizations, to understand the causal reasons, analyze the benefits and shortcomings of the procedures and provide the information for the reference of restorers. In the meantime, the restorative materials collected during the study will be analyzed, and the results shall provide guidance to restorers in choosing the appropriate restorative materials. 2. Use of indigenous Taiwan tree species in the making of special functional papers“Special functional papers” are papers with specialized properties and uses. The papers have high-value addition and economic efficiency. Furthermore, these papers can be developed through the use of native log production with low productivity or reconsidering using abandoned production facilities to produce. Thus, in several advanced papermaking countries, many small mills would regard production of special functional papers as a priority strategy in sustainable development when retrofitting or remodeling the production lines. However, there is seemingly a lack of R&D effort in developing specialty papers here in Taiwan. This study purports to investigate the suitability of use indigenous tree species in the production of various special functional papers. The main objective is to allow the pulp and paper producers to grasp both raw material supply and the know-how in the production of special functional papers. 3. Applying near-infrared spectroscopy (NIRS) to the analysis of pulp chemical composition and physical properties of handmade papersThe raw materials for pulp and paper are mainly plant fibers. There are numerous varieties of plant fiber genres which endow the resulting pulp and paper with different physical strengths and optical properties. Hence, analyzing the chemical compositions of a pulp is important to the pulping and papermaking production and assurance of the paper properties. The present standard methods of analyzing pulp chemical composition and paper physical properties require both large amounts of samples and tedious, time-consuming procedures. These pose a disadvantage to the pulping processes, as timely adjustment is voided. Near infrared spectroscopy (NIRS) has good penetration of substances, its analysis is fast and low-cost. The results are with good reproducibility, repeatability and nondestructive. The method has seen wide uses in chemical engineering, food science, and agriculture fields. However, there are fewer studies applying the technique to pulp chemical compositions and handsheet physical properties. Therefore, this study propose to apply NIRS to pulp raw material on their pulp compositions and the resulting handsheet properties. We hope to establish experimental protocols for novel, accurate, rapid, and nondestructive analytical methods for the pulp and paper industry, to allow advances in the industrial technologies. If the program proceed smoothly as planned, we expect the results and experience gained in the process shall allow rapid QC and prediction of properties, which are important to the optimization of the industry and might eventually bring substantial economic efficiency and social benefits. city. results are with good reproducibility, repeatability and nondestructive.
