Abstract
This research aims to improve the durability properties of natural dyes on natural fibers. The natural dye from the core Fang and water dyed shades of orange-red with agents attached (Mordant), which naturally include lime water containing calcium hydroxide (Calcium hydroxide, Ca (OH). 2) from rice husk ash and water containing potassium potassium hydroxide (potassium hydroxide, KOH) to aid adhesion include aluminum sulfate synthesis Hexa Child high Rate (Aluminium sulphate Hexadecahydrate, Al2012S3. 16H2O) Copper (Copper sulphate, CuSO4) and iron salts (iron (II) sulphate, FeSO4.7H2O) to dye yarn with cotton and silks are made by the Pre-mordanting. Then study the staining. Thermal properties Morphological properties Light fastness properties And properties, fastness to washing, which found that the efficiency of the dye of iron salts are substances that stick with the ability to absorb color (% Dye exhaustion) and the ability to attach color (% Dye fixation). highest in cotton yarn and silk. The use of lime water is chemically bonded to make the cotton yarn with a starting temperature of decomposition increases. And the use of copper sulfate or iron salts are substances that stick made of silk with a starting temperature of decomposition higher. Testing results showed that morphology Wave number of cotton yarn and silk dyed with substances that stick to the same place. The graph has increased as a result of the welding of metal bonding agent attached to the fibers. Testing light fastness. Using yarn, cotton and silk for 17 days found that the colors have faded fabric dyes to color all gone. The durability of the fiber dyed with natural substances identified in the poor and very poor. The fiber dyed synthetic substances identified in moderate to fairly good. Testing fastness to washing agent is bonded to the fibers, synthetic dyes can seal well agents adhere nature. But the fall colors of the synthetic substance that attaches worse nature.
