Problems solved by technology

[0002] After the cotton is harvested every year, a large amount of cotton stalks are discarded or directly burned, causing great environmental pollution. In the prior art, some willow weaving households use cotton stalks in the weaving process to weave various handicrafts, but Because the mechanical properties of cotton stalks are not ideal, it is very easy to break and crack the cotton stalks during the weaving process, and the color of the cotton stalks is single and dull, so that the cotton stalks cannot achieve a good performance in the field of weaving handicrafts. Utilization, although there is a dyeing technology for straws in the prior art, the current technology is used to dye cotton stalks, the coloring is extremely difficult, and the coloring will memory fade and change color; therefore, it is urgent to invent a kind of enhanced cotton The dyeing method of the mechanical properties of the stalks can not only solve the environmental pollution caused by burning cotton stalks, but also increase the economic income of cotton farmers and promote sustainable development

Abstract

The invention belongs to the technical field of biological treatment of cotton stems, and especially relates to a dyeing method for enhancing the mechanical performances of cotton stems. The method concretely comprises the following steps: (1) carrying out constant-temperature steam treatment on the cotton stems, taking out the cotton stems, carrying out constant-temperature freezing treatment, taking out the cotton stems, carrying out constant-temperature steam treatment, and taking out and cooling the cotton stems; (2) immersing the cotton stems in an aqueous solution of aluminum sulfate ata kept temperature, removing the obtained leachate, and carrying out hot pressing drying; and (3) immersing the cotton stems in a coloring agent, applying ultrasonic waves to carry out ultrasonic treatment, taking out the obtained leachate, and airing the cotton stems to reach a constant weight. The method has the advantages of high coloring fastness, no color fading, no color change, bright color, great improvement of the utilization values and the utilization effect of the cotton stems, effective improvement of the tensile strength and the elastic modulus of the cotton stems, enhancement ofthe mechanical performances of the cotton stems, improvement of the braiding performance in the braiding process, improvement of the use performances in the use process, and great prolongation of theservice life.
