Description
A process of loading yarns or fabric with minerals or organic materials. Weighting fabrics increases their body, thickness and stiffness. From early times, silk fibers were sometimes weighted with sugar or gum to replace sericin that was lost during processing. From as early as 1548, tannins were used for weighting silk, often in combination with iron salts. Iron salts (sulfate, acetate, nitrate, tannate) were later used as a mordants and weighting agents in blue and black silks. From the mid-19th century, silk was weighted industrially using tin salts. By the end of the 19th century, several other metal salts were also being used. Metal salts usually accelerate degradation of the silk fibers. Examples of materials that have been used for weighting fabrics are: sugar, gum, starch, chalk, oil, wax, polyvinyl acetate, acrylic polymers, tannins, and inorganic salts of aluminum, tin, iron, lead, magnesium, tungsten, and zinc.
