Abstract:
Silk fabric was dyed with the colourant extracted from Laccifer Lacca Kerr. by using post-mordanting process and pad-dry technique. The effect of metal mordantats at different mordant concentration levels on their colour strength was also investigated. Silk fabrics dyed with Laccifer Lacca extract showed a light pink shade, while those dyed with alum and stannous chloride produces pinkish-red colour. Silk mordanted with CuSO4 gave a purple red colour, while those dyed with FeSO4 had a reddish-gray colour. The fastness properties ranged from fair to good, while washing fastness was poor level.

Abstract:
Laccifer lacca has generally been used as pigmenting, coloring agent and dying in chemical industry. Although, it has wide range of industrial applications, but inappropriately, due to lesser availability of data, it has been ignored. Keeping in mind, the wide application of Laccifer lacca, we tried to report the in-silico anti-cancer effects. The experimental techniques used to determine the structure was X-RAY diffraction.

Abstract:
Abstract A new method has been proposed for detection of lac color in food. Lac color is a natural color additive derived from a secretion of the insect Coccus Laccae (Laccifer lacca Kerr). It is extracted from food with methanolic oxalic acid and eluted from a column of Amberlite XAD-2 with the same solvent. The fraction containing the lac color is treated with diazomethane to produce 2 reddish-orange markers. The marker species in the reaction mixture are detected by both thinlayer chromatography and reverse-phase liquid chromatography.

Abstract:
Lac insect (Laccifer lacca Kerr) is phytophogus insect, that feed on Kesambi Tree (Schleichera oleosa Merr). During its life cycle, lac insect has been producing secretion in liquid form, known as LAK and having many uses, such as varnish/polish, food cover, drug capsule, cassette ribbon, etc. In 2005, Perum Perhutani has produced 60.547 kg LAK pellets, but has not fulfilled yet market demand. Cultivation technique is still conducted in a very sampling, and easy to be studied. Investment in developing lac insect is also profitable, and promising. There are two choices of management schemes in

Abstract:
Lac insects (Laccifer lacca Kerr) live parasitically on “kosambi” plants, and produce resins that are called lac. Lac are used for electronics, printing, textile, clothing, cosmetics, and food industry. The insects also live on various plants. The goal of this research was to evaluate the population quality of Lac insect that live on three host plants. The best parameter for population quality was biomass or lac production. Three host plants were inoculated by broods. The result showed that “kosambi” was the best host plant for the insect due to higher biomass (i.e lac production) than “kabesa

Cold-pad-batch technique of silk dyeing fabric with two natural dyes (Laccifer lacca Kerr. And Garcinia dulcis (Roxb.) Kurz bark) using pre-mordant are performed using 3 different mordants namely, alum, tartaric acid and ferrous sulfate. The study showed that color intensity (K/S) slightly increased when the batching time increased from 1 to 24 hours. Dyed silk fabrics have different color shades depending on the types of mordant applied. Ferrous sulfate and alum was found to be the best mordants for improvements of color depth.
