Description
Technical Field
The invention relates to a method for enhancing the moisture absorption of sodium periodate-cotton oxide fabric, belonging to the technical field of textile printing and dyeing.
Background
The cotton fiber is a polysaccharide substance whose basic constituent substance is cellulose, and has the characteristics of moisture absorption, heat preservation, heat resistance, alkali resistance, sanitation and the like. Generally, cotton fibers have a strong absorption capacity for gaseous moisture, i.e., have a good moisture absorption. The hygroscopicity of the fibers depends mainly on the chemical structure of the fibers, i.e. the polarity and number of hydrophilic groups on the macromolecular chains of the fibers. Normally, cotton fibers absorb moisture from the surrounding atmosphere, making them soft and not stiff. If the humidity of the cotton cloth is increased and the ambient temperature is higher, the moisture content in the fiber can be evaporated and dispersed, so that the fabric keeps a water balance state and people feel comfortable.
After the cotton fabric absorbs moisture, the electrostatic property, the mechanical property, the friction property, the optical property and the like of the cotton fabric are changed, the relationship with the dyeing, finishing effect and the like of the textile is close, and the size stability of the textile is also influenced. Therefore, the moisture absorption of the fiber is an important characteristic of the fiber for clothing, and is very important in the production process. The moisture absorption of cotton fabrics is often expressed in terms of moisture regain and moisture content. The moisture regain is the percentage of the mass of water in the textile fibres relative to the mass of the absolutely dry fibres, and the moisture content is the percentage of the mass of water contained in the textile fibres relative to the mass of the fibres not dried.
In order to expand the application range of cellulose substances such as cotton and the like, periodate is often used in industry to carry out selective oxidation treatment on the cellulose substances, and the prepared product has the characteristics of good biocompatibility, degradability, environmental friendliness and the like, and can also be applied to the fields of fluorescence, energy storage, chelation, immobilized enzyme and the like, so that the research on the periodate is a hotspot in recent years. However, after periodate oxidation, glucose residual groups in the cotton fiber macromolecules are broken, and hydroxyl groups at the 2 and 3 positions are converted into aldehyde groups, so that the hygroscopicity of the cotton fiber macromolecules is remarkably reduced, and the comfort, the colorability and the like are adversely affected.
Disclosure of Invention
The method utilizes the synergistic use of the cellulase and the pectinase to modify the cotton fabric subjected to the sodium periodate oxidation treatment, and effectively solves the problem of reduced hygroscopicity caused by oxidation.
The invention adopts the following process:
(1) adding cellulase and pectinase in a mass ratio of 2:1 into water, and fully stirring for dissolving;
(2) soaking the cotton fabric treated by the sodium periodate in the solution, controlling the bath ratio to be 20:1, and the mass ratio of the cotton fabric to the cellulase and the pectinase to be 100:1:0.5, and then heating the solution to 50 ℃ for treatment for 1-3 h;
(3) taking the cotton fabric out of the solution, dewatering and airing.
Firstly, adding cellulase and pectinase with the mass ratio of 2:1 into water, and fully stirring and dissolving. Cellulase and pectinase are commercially available enzyme preparations for textile use. The cotton fabric treated with sodium periodate was put into the above solution. Sodium periodate is oxidized to selectively oxidize the macromolecules of the cotton fibers, and partial 2-and 3-site hydroxyl groups are converted into aldehyde groups, so that the moisture absorption is obviously reduced. Controlling the bath ratio to be 20:1, controlling the mass ratio of the cotton fabric to the added cellulase and pectinase to be 100:1:0.5, and then heating the solution to 50 ℃ for treatment for 1-3 h. In the process, the cellulase and the pectinase generate structure extension and association, and are transferred to and attached to the surface of the oxidized cotton fabric and generate binding reaction with the oxidized cotton fabric, so that the spatial structure, amino acid distribution, interaction and the like of the cellulase and the pectinase are further promoted to be adjusted, the polarity, the affinity and the hydrophobicity and the charge distribution characteristic of the surface of the fabric are synergistically changed, and finally, the hygroscopicity of the surface of the oxidized cotton fabric is improved. And finally, taking the cotton fabric out of the solution, dehydrating and airing.
Detailed Description
The invention is further illustrated by the following comparative examples and examples.
Example 1

(1) adding cellulase and pectinase in a mass ratio of 2:1 into water, and fully stirring for dissolving;
(2) adding a cotton fabric into the solution, controlling the bath ratio to be 20:1, and the mass ratio of the cotton fabric to the cellulase and the pectinase to be 100:1:0.5, and then heating the solution to 50 ℃ for treatment for 1 h;
(3) taking the cotton fabric out of the solution, dewatering and airing.

(1) adding the same cellulase as in example 1 into water, and fully stirring for dissolving;
(2) adding a cotton fabric into the solution, controlling the bath ratio to be 20:1 and the mass ratio of the cotton fabric to the cellulase to be 100:1, and then heating the solution to 50 ℃ for treatment for 1 h;
(3) taking the cotton fabric out of the solution, dewatering and airing.
