Acidic cellulase complex and preparation method thereof

Abstract

The invention relates to a novel acidic cellulase complex and a preparation method thereof, and belongs to the technical field of cellulase complexes. The acidic cellulase complex comprises the following raw materials in percentage by weight: 5%-30% of acidic cellulase; 5%-25% of a resist agent; 0.5%-5% of a re-deposition resistant agent; 1-7% of sodium dihydrogen phosphate; 0.5 to 1.5% of disodium hydrogen phosphate; 0.5%-5% of an anti-wrinkling agent; 0.5 to 5% of urea; 0.5%-5% of sodium nitrilotriacetate; 10%-60% of sodium sulfate; 1%-5% of a swelling agent; and 0.5%-2% of a preservative. According to the acidic cellulase complex, a co-solvent is added on the basis of ensuring the washing activity of cellulase, so that the solubility, especially the low-temperature solubility, of a resist agent in water is improved, and the washed garment fabric has a relatively good dye-resistant effect; meanwhile, the anti-wrinkling agent is added, so that the anti-wrinkling effect of the garmentfabric in the washing process is enhanced, the anti-wrinkling grade reaches 3.5 or above, and the visual aesthetic feeling of the fabric is improved while the texture of the fabric is protected.

Description

technical field [0001] The invention belongs to the technical field of cellulase complexes, and in particular relates to a novel acidic cellulase complex and a preparation method thereof. Background technique [0002] With the development of the textile and garment industry, high-efficiency and low-pollution technologies are increasingly recognized; cellulase is a biological enzyme, which has high efficiency and low environmental pollution, and at the same time, cellulase can effectively improve the quality of fibers. performance; therefore, cellulase has been widely used in the textile and garment industry. However, pure cellulase is easily disturbed by external conditions during use, and the use effect is not ideal. In order to obtain an ideal cellulase preparation, the compound usually contains buffers, anti-dyeing agents, desiccants, and preservatives. , and substances that increase cellulase activity. [0003] In the cellulase compound composition, the anti-dyeing age...

Problems solved by technology

However, pure cellulase is easily disturbed by external conditions during use, and the use effect is not ideal. In order to obtain an ideal cellulase preparation, the compound usually contains buffers, anti-dyeing agents, desiccants, and preservatives. , and substances that increase cellulase activity, etc.

[0003] In the cellulase compound composition, the anti-dyeing agent is usually a non-ionic surfactant, which has little solubility in water at room temperature, and the washing process is usually carried out at a relatively high temperature (45°C and above), but high-temperature washing Not only lead to higher energy consumption but also reduce the activity of cellulase

At the same time, the currently produced cellulase preparations usually pursue economic indicators such as cellulase washing activity and washing efficiency in the washing process of clothing fabrics. However, with the improvement of living standards and the abundance of materials, people There are also new requirements for wearing comfort and aesthetics. For example, the wrinkling of clothing fabrics during washing will affect the overall comfort and aesthetics of clothing fabrics.
