Sylic Textile Auxiliaries FAQ

A What does sequestering agent mean? In chemistry, a sequestering agent is an organic compound capable of linking metal ions or molecules together to form complex ring-like structures known as chelates. Although similar, a sequestering agent is different than a chelating agent.

A A sequestrant is a food additive which improves the quality and stability of foods. A sequestrant forms chelate complexes with polyvalent metal ions, especially copper, iron and nickel, which can prevent the oxidation of the fats in the food. Sequestrants are a type of preservative.

A Sequestering agent or chelating agent remove a metal ion from a solution system by forming a complex ion that does not have the chemical reactions of the ion that is removed. Sequestering agents are used to eliminate water hardness and heavy metals, such as iron and copper which can affect the scouring process.

A Advantages. Enzyme washing is considered more sustainable than stone washing or acid washing because it is more water efficient. Residual pumice fragments from stone washing demand a lot of water to be eliminated, and acid washing involves multiple wash cycles to produce the desired effect.

A A lipase enzyme in combination with a protease enzyme has been used for dewaxing and degumming of silk and the combined effect of dewaxing and degumming on weight loss, wettability, dye uptake, yellowing, microscopic structure, handle and lustre has been studied

A The enzymes used in the textile field are amylases for desizing of cotton and cellulases for denim finishing and biopolishing.

A The specific textile enzymes used are amylases, catalase, and laccase for removing the starch, degrading excess hydrogen peroxide, textile bleaching, and lignin-degrading.

A Enzymes are used in the textile industry because they accelerate reactions, act only on specific substrates, operate under mild conditions, are safe and easy to control, can replace harsh chemicals and enzymes are biologically degradable.

A Sodium alginate is the sodium salt of alginic acid. Unlike alginic acid, sodium alginate is soluble in both hot and cold water. This makes it ideal in various applications to achieve viscous solutions at low concentrations, for gel formation, film formation and for its suspension capabilities.

A Sodium alginate is a high‐molecular‐weight polymer naturally occurring in brown algae. The use of sodium alginate in animal nutrition is considered safe for the consumers and the environment.
