preparation example Construction

[0022] A preparation method of Sphingomonas fermentation extract, comprising the following steps:

[0023] (1) Add 15-20% water by weight of the fermentation liquid and 3-5% diatomite by weight of the fermentation liquid to the Sphingomonas fermentation liquid, and stir for 20-30 minutes at a speed of 250-350 rpm , followed by plate and frame filtration, discarding the filter cake, and collecting the filtrate;

[0024] (2) The collected filtrate is ultrafiltered by a hollow fiber ultrafiltration membrane. The molecular weight cut-off of the hollow fiber ultrafiltration membrane used is 15~25KDa. Wash and filter with deionized water until the final concentrated solution is 6-8% of the volume of the feed liquid;

[0025] (3) Adjust the pH of the obtained final concentrated solution to 2.0 to 4.0 with a sulfuric acid solution with a concentration of 2.0 to 3.0 mol / L, and then use a cation exchange resin to adsorb the final concentrated solution with an ion column diameter-to-hei...

Embodiment 1

[0038] Prepare the Sphingomonas fermentation extract of the present invention according to the following steps:

[0039] (1) Add 15% water of fermented liquid weight and 3% diatomite of fermented liquid weight in Sphingomonas fermented liquid, stir 20 minutes according to the speed of 250 revs / min, carry out plate frame filtration subsequently, discard Remove the filter cake and collect the filtrate;

[0040] (2) The collected filtrate is carried out ultrafiltration by hollow fiber ultrafiltration membrane. The molecular weight cut-off of the hollow fiber ultrafiltration membrane used is 15KDa. At 8 o'clock, add deionized water equal to the volume of the concentrated solution to wash and filter until the final concentrated solution is 6% of the volume of the feed liquid;

[0041] (3) The obtained final concentrate is adjusted to pH 2.0 with a sulfuric acid solution of 2.0 mol / L in concentration, and the final concentrate is adsorbed with D001 cation exchange resin, and the di...

Abstract

The invention discloses preparation of a sphingomonas fermentation extract and application to a printing and dyeing refining agent. The preparation method of the extract comprises the following steps:adding water and kieselguhr into sphingomonas fermentation broth, stirring and performing frame filtering; discarding the filter cake; collecting the filtrate and performing ultrafiltration with a hollow fiber ultrafiltration membrane; washing with deionized water; adjusting the pH of the final concentrated solution, and adsorbing with cation exchange resin; then eluting by adopting a NaCl solution as eluant; collecting the eluant; performing rotary evaporation concentration and vacuum drying to obtain a sphingomonas fermentation broth extract. The prepared sphingomonas fermentation broth extract is applied to the printing and dyeing refining agent and can effectively remove impurities such as grease and wax in the raw material fiber; moreover, the use of harmful substances is avoided, and the usability and environmental protection property of the printing and dyeing refining agent are improved.

Description

technical field [0001] The invention relates to the technical field of printing and dyeing, in particular to a preparation method of a sphingomonas fermented extract and its application in a printing and dyeing refining agent. Background technique [0002] In the textile industry, desizing, scouring, bleaching and mercerizing of fabrics are all important processes before fabric printing and dyeing, which are collectively called scouring. During the refining process, scouring agents and other printing and dyeing auxiliaries with various functions are required. . Refining agent is a commonly used auxiliary agent for printing and dyeing of cloth. Initially, cotton fiber contains pectin, wax, protein and pigment, etc., which will affect the properties of the fabric and the printing and dyeing process, which is not conducive to processing and use. People often carry out pre-refining treatment on fabrics by scouring and bleaching pectin, cotton fat, cotton wax and other impuritie...
