Problems solved by technology

After the temperature rises to 60°C, if the holding time is long, it is easy to cause greater damage. If the holding time is short, the dye will be adsorbed unevenly. Adding alkali to fix the color will easily cause dyeing and flowering.

Embodiment 1

[0040] Embodiment 1 adopts the preparation of the Chaetomium thermophila cellulase expressed by Trichoderma reesei (seeing the patent application number is

[0041]

[0042]Example 1) of the specification of CN103343111A of the invention patent application publication of 201310280267.6.

Embodiment 2

[0043] Example 2 uses the preparation of Chaetomium thermophila cellulase expressed by Pichia pastoris (see Example 3 of the description of the invention patent application publication CN103343111A with the patent application number 201310280267.6).

Embodiment 3

[0044] Example 3 Qualitative test of the halophilic property of Chaetomium thermophila cellulase (influence of different sodium sulfate concentrations on the polishing effect of neutral cellulase)

[0045] 1. Under the condition of 60°C and the pH value of 7.0, the fabric was polished for 60 minutes with 1.0 g / L of the Chaetomium thermophila cellulase prepared in Example 1, and the weight loss rate under different sodium sulfate concentration conditions, see Table 1 and image 3 (The higher the weight loss rate, the better the polishing effect).

Abstract

The invention discloses an application of thermophilic Chaetomium cellulose to polishing, dyeing and one-bat technology. The thermophilic Chaetomium cellulose is expressed via Trichoderma reesei or pichia pastoris; the thermophilic Chaetomium cellulose is neutral cellulose having a halophilic function; salt with high concentration has obvious lifting action on activity of neutral cellulose; the optimal action temperature of the neutral cellulose is 57 to 63 DEG C, so polishing temperature and dyeing temperature are the same; during the polishing, even dyeing can be achieved and guaranteed.

Description

technical field [0001] The invention relates to the field of biological enzyme preparations, in particular to a new application of a chaetomyces thermophilic cellulase, in particular to an application of a chaetomyces thermophilic cellulase in a one-bath polishing and dyeing process. Background technique [0002] In the traditional polishing and dyeing process of cotton knitted fabrics, the polishing and dyeing processes are carried out separately. The general process is as follows: figure 1 As shown, in the above process, acid cellulase was used at the earliest, and the pH value was generally controlled at around 4.5-5.0. With the development of enzyme preparations, especially the progress of neutral cellulase technology, it can effectively remove hairiness on the surface of fabrics under neutral conditions, and the adsorption process in the early stage of dyeing is generally carried out under neutral conditions. [0003] In recent years, as people pay more and more attent...
