This research studied the juice extraction process from mangosteen peel with water solvent and the paramesters influencing on extraction process such as extraction temperature, extraction time and extraction ratio, and evaluating the juice of extract by determining extraction efficiency, color saturation of fabric and color fastness of silk fabric. | Journal of Science and Technology 54 (4B) (2016) 94-101 OPTIMIZATION OF THE AQUEOUS EXTRACT PROCESS FROM MANGOSTEEN PEEL FOR DYEING SILK Hong Phuong Pham Thi1, *, Linh Hoang Thi2, Trung Kien Tran3, Tan Vu Duc4 1 Industrial University of Ho Chi Minh City, 12 Nguyen Van Bao, Ward 4, Go Vap District, Ho Chi Minh City 2 3 Hung Yen University of Technology and Education, Khoai Chau District, Hung Yen Province Hanoi University of Science and Technology, 1 Dai Co Viet, Hai Ba Trung District, Ha Noi 4 Hanoi Industrial Textile Garmanet University, Le Chi Commune, Gia Lam District, Ha Noi * Email: pthphuong1978@ Received: 15 August 2016 2016; Accepted for publication: 10 November 2016 ASBTRACT This research studied the juice extraction process from mangosteen peel with water solvent and the paramesters influencing on extraction process such as extraction temperature, extraction time and extraction ratio, and evaluating the juice of extract by determining extraction efficiency, color saturation of fabric and color fastness of silk fabric. The research results showed that the juice extracted from mangosteen peel can be used to dye silk fabric with high color strength and fastness. And the results of research will bring the efficiency of environmental, economy and society; and will meet urgent demands today. Keywords: silk, natural color, mangosteen peel, extracting and testing a natural plant dye. 1. INTRODUCTION Garcinia mangostana Linn is one of the local fruits of Viet Nam and the South Eastern area. Magosteen Rind has been used as a natural dye in textile applications so the component of the aqueous extraction of mangosteen contains a variety of compounds chromophore such as gartanin, BR-xanthone A, 3-isomangostin, α-mangostin, garcinon D and other compounds. Moreover, the advantage of mangosteen peel is part of waste materials and mangosteen peel occupy 68 ÷ 70 % per mangosteen fruit [1, 2]. 2. MATERIALS AND METHODOLOGY . Materials Optimization of .
