Lysozyme
Lysozyme can serve as a natural anti infective substance with bactericidal effects, including antibacterial, anti-inflammatory, and accelerating tissue recovery. Commonly used for human skin care.
Lysozyme
Lysostaphin is a Zn2+containing metalloproteinase with endopeptidase activity, which can specifically hydrolyze the peptidoglycan pentaglycine peptide bridge (peptide bond formed by the second and third Gly positions) of bacterial cell wall, thereby rapidly dissolving the bacterial cell wall and producing wall breaking and bacterial lysis.
pectinase
Pectinase is mainly composed of pectinase, polygalacturonase, pectinate lyase, and pectinesterase. Pectin substance is a highly esterified polygalacturonic acid. When pectinase acts on pectin substances, pectin lyase, polygalacturonase, and pectinate lyase directly act on the sugar bonds inside the pectin polymer molecular chain, while pectin esterase hydrolyzes polygalacturonase, creating more positions for polygalacturonase and pectinate lyase.
lipase
Lipase can hydrolyze fats into glycerol and fatty acids, which are further subjected to B-oxidation. Each time, a C2 compound is removed to generate acetylCOA (N-cyclohexyloctylamine), which enters the TCA (tricarboxylic acid) cycle for complete oxidation or enters the glyoxylate cycle to synthesize sugars.
Lipase (EC 3.2.2.3, glycerol ester hydrolase) is an enzyme that breaks down natural oils and fats. It is mainly used for degreasing treatment of silk spinning raw materials in textile processing; At the same time, lipase is a good detergent in wool washing, which can remove attached impurities and wax, making wool spinnable; Refining cotton fabrics can effectively remove the fat and wax from cotton; Treating polyester can improve its surface hydrophilicity.
protease
The proteases secreted by microorganisms vary depending on the bacterial species. For example, Bacillus subtilis secretes gelatinase and casein enzymes, which can hydrolyze gelatin and casein; Streptomyces fischeri secretes keratinase, which can hydrolyze keratin from animal hair, horns, and hooves. Proteases break down proteins into peptides, which are then hydrolyzed by peptidases into amino acids.
cellulase
Cellulase is a multi-component enzyme system, and most of the cellulases used in the textile industry are manufactured by fungi of the genus Trichoderma. The cellulose disaccharide hydrolase in cellulase, also known as exocellulase, is composed of two enzymes, CHB I and CHB II, while endoglucanase, also known as endocellulase, is composed of at least five cellulases (EG I, EG II, EG HI, EG IV, EG V). In addition, there are 13 glucuronidases. These cellulases have a synergistic effect in the hydrolysis of cellulose.
Catalase
Catalase is an oxidoreductase that catalyzes the decomposition of hydrogen peroxide into water and oxygen. It is mainly used to remove residual hydrogen peroxide after bleaching processes, improve subsequent dyeing performance and quality, and there is no excessive danger. Catalase can also be used for oxygen bleaching biological purification treatment in yarn dyeing machines, overflow jet dyeing machines, winch dyeing machines, and roll dyeing machines.
amylase
Amylase is a general term for enzymes that hydrolyze starch and glycogen. It is usually used to catalyze the hydrolysis of starch slurry on fabrics. Due to the high efficiency and specificity of amylase, the enzyme has a high desizing rate, fast desizing, less pollution, and the product is softer than acid and subtraction methods without damaging fibers. There are many types of amylase, and according to different fabrics and equipment combinations, the process flow is also different. The desizing methods used include impregnation, stacking, roll dyeing, continuous washing, etc. Due to the small mechanical action of amylase desizing and the small amount of water used, it can achieve desizing effect at low temperature conditions, with distinct environmental characteristics.
