Problems solved by technology

Leaf sheaths and leaves are good weaving materials after drying. At present, cattail leaf sheaths and leaves are mostly used for primary processing such as weaving cattail fans, cattail mats, and cattail bags, and the added value of the products is not high.

Embodiment 1

[0017] Embodiment 1: After preliminary water washing and mechanical separation of cattail leaves, a single factor experiment was used to carry out degumming treatment by a biochemical combined degumming method. The technological process is pickling-enzyme cooking-alkali cooking-bleaching-pickling-oiling.

[0018] In the process flow, under the condition that other conditions remain unchanged, the degumming treatment is carried out respectively at a biological enzyme concentration of 10-40g / L, a time of 60min-90min, and a temperature of 55-65°C.

Embodiment 2

[0019] Embodiment 2: After preliminary water washing and mechanical separation of cattail leaves, an orthogonal experiment was carried out to carry out degumming treatment by a biochemical combined degumming method. The technological process is pickling-enzyme cooking-alkali cooking-oiling.

[0020] In the orthogonal experiment, under the condition that other conditions remain unchanged, an orthogonal experiment table is designed with the concentration, time and temperature of biological enzymes as factors. The concentration range of the biological enzyme is 10-50g / L, the time is 50min-90min, and the temperature is 50-70°C.

Embodiment 3

[0021] Embodiment 3: After preliminary water washing and mechanical separation of the cattail leaves, the average level experiment was used to carry out the degumming treatment by the combined biochemical degumming method. The technological process is pickling-enzyme cooking-alkali cooking-oiling.

[0022] The average level experiment is designed according to the uniform data table constructed by the application principle of number theory in multidimensional numerical integration. Under the condition that other conditions remain unchanged, the concentration of biological enzyme is selected to be 10-50g / L, the time is 60min-90min, and the temperature is 50-65°C to carry out the degumming treatment respectively.

[0023] Cattail fiber performance test and results

[0024] Fiber length, fineness and strength tests were carried out for the prepared cattail fibers. The measured cattail fiber length is 110.0-220.0mm; fiber fineness is 35.0-86.0Nm; fiber strength is 37.0-55.0cN / tex...

Abstract

The invention discloses a cattail fiber and a preparation method thereof. The invention belongs to the field of materials, in particular to a natural plant fiber. The cattail fibers are selected from natural cattail leaves and subjected to preliminary water washing and mechanical separation, and are degummed by a combined biochemical method, and the degumming process is optimized by designing a single factor experiment, an orthogonal experiment and an average level experiment to obtain a cattail process fiber After oiling and combing, the fiber is tested for performance. Aiming at the problems of long process, high labor cost and serious pollution of traditional retting degumming and existing single chemical degumming method, the present invention adopts biochemical combined degumming technology to shorten the process flow and minimize the consumption of chemical reagents, thereby reducing pollution , to achieve degumming effect and ensure fiber quality. Cattail is rich in resources and has the functions of clearing heat and keeping warm. The developed cattail fiber can be used as a new spinning raw material, and cattail fabric can be further developed to enrich the types of textile products.

Description

technical field [0001] The invention belongs to the field of materials, in particular to a natural plant fiber. Background technique [0002] In recent years, with the increasing shortage of energy and resources in the world, the research and development of new materials has attracted people's attention and widespread attention. Among them, the development and research of new plant fibers has become a hot spot for scholars at home and abroad. A large number of existing cellulose fibers in nature have not been developed and utilized. The global natural cellulose output reaches 100 billion t / a, while the world's textile industry uses less than 22 million t / a of cellulose. my country is a large agricultural country, rich in natural cellulose raw materials, with an output of 1.145 billion t / a. Among the existing forestry by-products, there are a large amount of cellulose raw materials that can be processed with biomass products, providing a large amount of "green" cellulose raw...
