The purposes of this research were1) to study the process of dried banana leaves’ dyeing with natural dye and scientific dye and 2) to study the results of dried banana leaves’ dyeing with natural dye and scientific dye. Dried banana leaves were bleached by using three formulas as follows: 1. Mix Haiter with water in the ratio 1:1 2. Mix Haiter with water in the ratio 2:1 and 3. Mix Haiter with water in the ratio 3:1. Soak 300 grams of the dried banana leaves for 5 days and record the results. The result of this experiment indicated that the third formula wassuitable to whiten and toughen dried banana leaves. After choosing the suitable formula for bleaching

A research study as Natural Dye Controlled and Applied to Karen Pattern Styles was divided to 2 main studies. The first was natural dye control by varying the condition amount of auxiliaries and mordanting process. The second study was developed and applied the natural shade color to the Karen patterns and using questionnaires as the tool for measure the customer satisfactions level. The results distributed to the target. All the results transferred to the target group at Bann Yang Nam Klad Tai Phetchaburi province. Natural dyed controlling was found the condition was reflect to shade of dye especially the primary condition of natural dye. Almost studied dyes were good using the primary condition as acid condition for Arceanut plam and Butterfly Pea the neutral condition for Sappan tree core of jack fruit tree and Ebony tree. However Curcumin was good dyeing in acid condition whereas the primary condition as neutral. The amount of auxiliary as salt was effect to deep of dye shade. The optimize stage was ranging about 10-20 g/l. Addition the pre mordanting was a good results for this research cause of forming the Chelate ring to bonding between dye and substrate. The natural dye applied into the Karen pattern was shown the modern style pattern and vast application for using and design products. The customer acceptances were good to excellent. The content distributed to the group thus it made a new knowledge occupational and immediately usage.

The aim of this research is to study white and colour resist printing of dye extracted from dry nipa palm shell. The printing recipes and fixation condition were studied in this work. The result of white resist printing showed that 30 % owp of sodium carbonate (Na2CO3) was used to be a resisting agent. The steam fixation for 15 minutes was suitable to show a good white resist printing in whiteness and sharpness of printing pattern. The whiteness value was 35.05. The washing and rubbing fastness were good to very good and light fastness was fair. The tensile strengths of warp and weft directions were decreased to 10.29 % and 4.25 % respectively. The colour resist printing was using Curcuma longa Linn. powder as illuminant dye. The dye was miscible in 30 % owp of sodium carbonate. The colour resist printing results were corresponding as white resist printing results. The 15 minute of steam fixation showed a good colour resist printing. The Curcuma longa Linn dye could be fixed on silk fabric and showed a good colour strength and sharpness of pattern. The washing and rubbing fastness were good to very good. And light fastness was fair. The tensile strengths of warp and weft directions were decreased to 18.37 % and 4.18 % respectively.

This research had an aim to develop an autoclave for using in natural dyes extraction and dyeing process. The autoclave used the stainless steel as the major material what it was a noble durable material and good resistance for the chemical used in the processes. The achievement results showed by the comparison data between the conventional process and the development using autoclave in term of extraction efficiency deep of shade (K/S) time equivalent process time and amount of gas consumption saver. The knowledge from the research would transfer to the target group at Bann Yang Nam Klad Tai Phetchaburi province. The results were following as 1. For the extraction process: the extraction process using 100oC for 45 min. They obtained product was the same dye quality but the autoclave process was smaller water evaporation as 26.71% whereas the conventional process was 41.99%. 2. For the dyeing process: All condition from the autoclave using make a deeper dye shade (K/S) than conventional process. The dyeing time equivalent as 15 minutes to make the depth shape via autoclave process as alike the conventional process for 45 min. 3. Saving time and gas consumption: the autoclave process could save 66.67% time process and 88.99% amount of gas consumption. 4. The Complacency for knowledge assignment: the satisfaction level in the content time and period was good. Furthermore the utilization the instructors and the value obtained were excellent. This research accomplished the study objectives. The results were not only corresponding to energy conservation but them also reducing the chemical toxic and pollutant vapor inhalant to the worker.

The aim of this reseach in to paint on silk fabric with batik technique using five natural dyes from neem tree bark lac mango leaves marigold and star gooseberry bark. The pre-mordant and after-mordant techniques were used in this work. There were 10 Mordants Aluminium Potassium Sulfate Copper Sulfate Sodium Dichromate Tannic Acid Tartaric Acid Tin (ll) Chloride and Calcium Acetate-Monohydrate were applied. The batik fabrics were characterized In color strength rubbing fastness washing fastness light fastness and stiffness. The result-indicated that silk Fabric painted with natural dye from neem tree bark could use all 10 mordants to improve color strength and gave various shade of color. The silk fabric painted with Natural dye from lac could not use all 10 mordants to improve color strength but it gave various shade. The silk fabric painted with natural dye from mango leaves marigold and star gooseberry bark showed that almost 10 mordants gave higher color strength and various shade. The mordanting technique would give good fastness and reduce the stiffness of batik fabric.
