Embodiment 1

[0031] The technical scheme adopted in the present invention is: a chitosan sericin protein complex finishing agent, and the preparation method of the complex finishing agent specifically comprises the following steps:

[0032]1). The dissolving of chitosan: join the chitosan of deacetylation degree 85% in the dilute acetic acid solution of 3% (v / v), make chitosan dissolve in the dilute acetic acid solution under stirring condition completely, obtain Mass concentration is 5% chitosan acetic acid solution, then joins in the above chitosan acetic acid solution with 0.5mol / L NaOH solution, stirs to neutrality and then filters, then washes and filters with deionized water several times, Get the chitosan solution of swelling state;

[0033] 2). Oxidation of chitosan: first configure 200mL of sodium carbonate-sodium bicarbonate buffer solution and control its pH value to 10, slowly add 0.20g of catalyst TEMPO and 1.8g of NaBr and make it completely dissolved in the buffer solution ...

Embodiment 2

[0064] The technical scheme adopted in the present invention is: a chitosan sericin protein complex finishing agent and its finishing method for cotton fabrics, and the preparation method of the finishing agent specifically comprises the following steps:

[0065] 1). The dissolving of chitosan: join the chitosan of deacetylation degree 75% in the dilute acetic acid solution of 4% (v / v), make chitosan dissolve in the dilute acetic acid solution under stirring condition completely, obtain Mass concentration is the chitosan acetic acid solution of 4%, then joins in the above chitosan acetic acid solution with the NaOH solution of 0.5mol / L and stirs to neutrality and then filters, then washes and filters with deionized water several times, Get the chitosan solution of swelling state;

[0066] 2). Oxidation of chitosan: first configure 200mL of sodium carbonate-sodium bicarbonate buffer solution and control its pH value to 10.5, slowly add 0.14g of catalyst TEMPO and 1.2g of NaBr a...

Abstract

The invention provides a chitosan sericin compound finishing agent and a finishing method for cotton fabrics. A preparation method for the compound finishing agent comprises the following steps that 1), chitosan is dissolved; 2), chitosan is oxidized; 3), the finishing agent is prepared; the finishing method for the cotton fabrics particularly comprises the following steps that 1), cotton fabricsare pre-treated; 2), the cotton fabrics are soaked; 3), the cotton fabrics are subjected to after-treatment; under the microwave radiation, after a TEMPO oxidation system is adopted for conducting C6modifying treatment on the chitosan, the chitosan and sericin are subjected to covalent cross-linking to obtain a novel ecological textile dyeing and finishing auxiliary agent, higher stability is achieved regarding the environmental condition, and the novel ecological textile dyeing and finishing auxiliary agent cannot be easily heated and influenced by environmental changes; when a cross-linkingagent is not added, the compound finishing agent directly treats cotton fiber products, the cotton fiber products have antibacterial and wrinkle proof functions and good function durability, and after the cotton products are washed, the sericin loss rate can be better controlled; by adopting the compound finishing agent, functional modification of the cotton products meets multiple requirements of ecology, multi-functionality and durability.

Description

technical field [0001] The invention relates to the technical field of functional finishing of cotton fabrics, in particular to a chitosan sericin complex finishing agent and a finishing method for cotton fabrics. Background technique [0002] Natural cotton fiber is an important textile raw material. It has many incomparable advantages, but it also has defects such as poor antibacterial performance, anti-wrinkle performance, single function, and low technical content. Faced with the continuous emergence of high-performance and multi-functional fiber varieties, people have put forward higher and higher requirements for the performance and functions of cotton fiber products. It has become an important task to develop multiple functional modification technologies for cotton fiber products and improve their added value and performance. research hotspots. In the traditional natural fiber modification in my country, while improving the fiber performance and endowing it with func...
