It is only recently (the first artificial dye was invented in 1857) that the textile industry has turned to synthetic dyes. Today, many craftspeople are rediscovering the joy of achieving colour through the use of renewable, non-toxic, natural sources. Natural dyes are inviting and satisfying to use. Most are familiar substances that will spark creative ideas and widen your view of the world. Try experimenting. Colour can be coaxed from many different sources. Once the cloth or fibre is prepared for dyeing it will soak up the colour, yielding a range of results from deep jew- el-like tones to dusky heathers and pastels. -
Star-K Kosher Certification - Kosher Consumer
Star-K Kosher Certification - Kosher Consumer back Facts on Wax: Are Vegetable and Fruit Waxes Kosher? Rabbi Dovid Heber, Star-K Kashrus Administrator You may notice at your favorite supermarket the following statement next to the prominent "Summer Fruits from California" banner: "Coated with food grade vegetable, petroleum, and/or shellac-based wax or resin to maintain freshness" on their favorite fruits and vegetables. What are waxes? Are there any Kashrus concerns? Let us examine some of the Kosher facts on wax. Waxes are not a new phenomenon, as they have been used domestically for over 60 years, on a wide variety of fruits and vegetables (see list). Waxes are derived from a variety of sources and are a cross combination of natural and synthetic ingredients. The most common primary wax ingredients are shellac, carnuba wax, or petroleum based wax. Less frequently used and more costly wax bases include beeswax and candelia wax. Shellac or lac resin is a product that is imported from India and is used in waxes for citrus fruits, apples and pears. It is a product that is derived from the secretions of the tiny lac insect. The lac insect secretes "lac-resin" from its glands onto a host tree. The resin is then gathered, crushed, sieved, washed and purified into food grade shellac. Horav Moshe Feinstein, zt'l explains in Igros Moshe Y.D. II 24 that shellac is Kosher. Rav Moshe zt'l discusses several reasons for this conclusion - most important the analogy between shellac - a secretion from a non-Kosher insect, and honey - a secretion from a non-Kosher insect. -

Ayurveda College Patna Abstract During this fast life every person fell into some or the other injuries due to trauma; either it may occur on roads with some weapons, in office or even in kitchen while doing household work. Acharya Sushruta has described six types of wounds which occur accidentally by sharp or blunt instruments called sadyo vrana or agantuja vrana (Su.Chi. 2/9). So, after going through different texts it has been found that resin of shorea robusta has been described to have good healing property. It is a good disinfectant, antiseptic and fumigant. 30 patients fulfilling the inclusion criteria of wound were randomly selected from OPD/IPD, Deptt. Of shalya, G.A.C.H., Patna. Dressing of the wound with the above drug was done to the subjects. The results were assessed in pre and post treatment designed proforma. In this group bleeding was completely relieved whereas more than 90% relief was obtained in pain, tenderness, size. Symptoms like itching sensation, color, surface, smell, discharge were relieved upto 50 to 75 % respectively. -
Particleboards from Durian Peel and Coconut Coir
The First Thai-Biomass Utilization Symposium __ _______________________________________________________ Effective Utilization of Forest Biomass for Regional People in Thailand Particleboards from Durian Peel and Coconut Coir Sarocha Charoenvai*, Jongjit Hirunlabh*, and Joseph Khedari* Abstract Manufacturing particleboards from tropical fruit peel particle; durian (Durio zibethinus ) peels and coconut coir ( Cocos nucifera ); with low thermal conductivity is the main purpose of this study. Two main parameters were investigated namely binder types, (UF 12%, PF 6% and IC 3%) and board density. In general, the effect of adhesive type on the properties of boards was not obvious whereas that of the density was more significant on most properties of boards. Experimental investigation indicated that the mechanical properties of all boards increased with increasing board density, but this decrease the dimension stability, expressed by the thickness swelling and the thermal conductivity as well.

Technology is used to manufacture materials from agricultural waste which is considered to substitute natural wood. The productivity of Thai fruit [1] is anticipated to increase in the future and the associated produced waste will lead to social and environmental problems, if we are unable to dispose them. -
The Moisture-Excluding Effectiveness of Finishes on Wood Surfaces
United States Department of Agriculture The Moisture- Forest Service Forest Excluding Products Laboratory Research Paper Effectiveness FPL 462 of Finishes on Wood Surfaces William C. Feist James K. Little Jill M. Wennesheimer Abstract Permeability to water vapor is one of the more important properties affecting the performance of coatings and other wood finishes. Often, one of the main purposes of finishing wood is to restrict moisture movement from the surroundings. We evaluated the moisture-excluding effectiveness (MEE) of 91 finishes on ponderosa pine sapwood, using the Forest Products Laboratory method in which finished and unfinished wood specimens in equilibrium with 30 percent relative humidity (RH) at 80 °F are weighed before and after exposure to 90 percent RH at 80 °F. Finishes with the best MEE were pigmented, nonaqueous (solvent-borne) finishes. Two-component epoxy paint systems had MEE values greater than 85 percent after 14 days when three coats were put on the wood. Molten paraffin wax and a sheathing grade, two-component epoxy material with no solvent were the very best finishes found in this study for controlling moisture vapor movement into wood. The MEE is a direct function of the number of coats of finish applied to the wood (film thickness) and the length of time of exposure to a particular humidity. Only 11 finishes were found to retard moisture vapor movement into wood with any degree of success over the relatively short time of 14 days, and then only when two or three coats were applied. These studies include evaluations of MEE by finish type, number of coats, substrate type, sample size, and time of exposure, and describe the effect on MEE of repeated adsorption/desorption cycles. -

What are the common Finishes? 1) Oil • Natural product extracted from walnut, linseed, Tung, soy bean, etc. • Polymerized oil is heated to about 500 degrees in absence of oxygen, dryers sometimes added. Goal is to dry faster • Provided a natural looking finish but limited protection 2) Shellac • Shellac is a resin secreted by the female lac bug on trees in the forests of India and Thailand. • Friction Polish – Shellac, Alcohol, Boiled Linseed Oil, Beeswax optional 3) Varnish • Synthetic product made by cooking a drying oil and add resin like urethane or Alkalyd. • Wiping Varnish – Varnish/thinner blend 4) Lacquer • Nitrocellulose lacquer is mostly solvent-based and comprised of plant-based substances like cotton, mixed nitric and sulfuric acids. 5) Wax • Beeswax, carnuba • Provides little protection but adds sheen and maintains natural color • Used as both a finish and a polish. -
NATURAL SPIRIT VARNISH RESINS SHELLAC Production
CHAPTER 5 NATURAL SPIRIT VARNISH RESINS SHELLAC ALTHOUGH shellac is not used in the varnish trade in such large quantities as other natural and synthetic resins it has attracted a considerable amount of interest. Much research and development work has been done. Source.—Lac is the secretion of an insect, Laccifer lacca, which swarms on the twigs of special trees. A comprehensive list of host trees is given by Parry.1 The insects extract sap from the twigs but its constitution and the nature of the process involved for the production of lac are not com- pletely understood. Gibson 2 suggests that if the food for the lac insect could be produced synthetically, the insect could be cultivated under ideal conditions. The greater part of the world's shellac supply comes from India. Assam, Burma, Indo-China and Siam supply smaller quantities. Attempts have been made to produce lac in Abyssinia. Two crops of lac are produced yearly. Climatic influences seem to alter the properties of the lac produced. In the areas west of Calcutta lac has a yellow or orange colour ; in Assam it is pale red, and dark red in Siam.3 Other variations in properties may be due to the type of host tree, the time of the crop and the district, species of lac insect and method of cultivation. Shellac as used by the varnish trade may vary in properties for various reasons, including method of production and time of storage. Production Sticklac.—The incrusted twigs are scraped to remove the lac and this crude product is known as sticklac. -

Application of Lac Dye in Shoe Upper Leather Dyeing
APPLICATION OF LAC DYE IN SHOE UPPER LEATHER DYEING APPLICATION OF LAC DYE IN SHOE UPPER LEATHER DYEING Amal Kanti DEB1*, Md. Aftab Ali SHAIKH1, Md. Zakir SULTAN2, Md. Israil Hossain RAFI1 1Institute of Leather Engineering and Technology, University of Dhaka, Dhaka-1209, Bangladesh 2Centre for Advanced Research in Sciences (CARS), University of Dhaka, Dhaka-1000, Bangladesh Received: 09.03.2017 Accepted: 25.04.2017 https://doi.org/10.24264/lfj.17.2.4 APPLICATION OF LAC DYE IN SHOE UPPER LEATHER DYEING ABSTRACT. Shoe upper leather samples were dyed with the natural lac dyes (byproduct of shellac and shellac products industry) extracted from washings of the stick lac by conventional methods. The aim of this research is to utilize this dye water and reveal the novel natural recipe for eco-friendly dyeing operation of shoe upper leather processing. The extraction of lac dye was carried out by using water at different temperatures. The lac dye was applied on the leather samples with and without using mordants; and three different mordants (CuSO4, FeSO4, [KAl(SO4)2]) were used following metamordanting method of dyeing. Absorbance and λmax of all dye liquors at different time intervals were determined by UV-visible spectrophotometer. The dyestuffs exhaustion and uptake were investigated and results showed that mordanted dyeing increased the dye uptake on leather than unmordanted dyeing. The FTIR analyses samples were carried out and it was found that lac dye could be mainly composed of -OH, -NH, >C=C<, >C=O, -COOH functional groups. The fastness properties such as fastness to washing, rubbing (dry and wet) and light of prepared leather samples were assessed.
