Description

Technical Field

[0001] The invention belongs to the technical field of fishing net line processing, and particularly relates to a method for preparing an anti-mildew fishing net line. Background Art

[0002] Fishing net line is made of high-quality natural fiber or chemical fiber through spinning. The raw materials for preparing fishing net line are high-quality natural fiber or chemical fiber, especially natural fiber is a biological material, rich in cellulose, which is a complex polysaccharide, providing nutrients for wood decay fungi and mold under a certain temperature and humidity environment, and is easily attacked by fungi and insects, thereby changing the appearance and reducing the quality. The current research on fishing net line mainly focuses on the exploration and utilization of new material resources, which greatly improves the utilization rate of resources. However, there is little research on improving the antibacterial and mildew-proof properties of fishing net line made of the most original natural fiber spinning. In addition, the current treatment methods are mostly to add mildew-proof and antibacterial ingredients in the processing of fishing net line, or to soak and sterilize the finished product, but the improvement effect is not good, and the effect of direct addition is short-lived, and it will still mold after long-term use. Summary of the invention

[0003] The purpose of the invention is to provide a method for preparing a mildew-proof fishing net line in view of the existing problems.

[0004] The present invention is achieved through the following technical solutions:

[0005] A method for preparing a mildew-proof fishing net line comprises the following steps:

[0006] (1) Calcination treatment:

[0007] The expanded perlite is placed in a muffle furnace for calcination, and after calcination, the expanded perlite is taken out for later use;

[0008] (2) Electron beam irradiation assisted bead milling:

[0009] The expanded perlite and sepiolite calcined in step (1) are placed in a bead mill at a weight ratio of 1:1 to 3 for grinding, and electron beam irradiation is performed at the same time. After the grinding, a mixed powder A is taken out for standby use;

[0010] (3) Cryogenic crushing treatment:

[0011] The mixed powder A obtained in step (2) is placed in a cryogenic pulverizer precooled with liquid nitrogen, and then the pulverizer is started to perform pulverization, and after completion, a mixed powder B is obtained for standby use;

[0012] (4) Soaking treatment:

[0013] The mixed powder B obtained in step (3) is immersed in the treatment liquid, and after completion, it is filtered out and dried to obtain the mixed powder C for later use;

[0014] (5) Melt spinning:

[0015] Weigh 75-85 parts of natural plant fiber of corresponding weight parts, 9-11 parts of the mixed powder C obtained after the soaking treatment in step (4), 12-16 parts of soybean lecithin, and 40-50 parts of deionized water, and place them together in a spinning tank for spinning treatment to obtain a monofilament for use;

[0016] (6) Fumigation treatment:

[0017] The monofilament obtained in step (5) is fumigated with steam generated by the fumigation liquid, and after fumigation, the monofilament is taken out for later use;

[0018] (7) Finished product preparation:

[0019] The monofilament after fumigation treatment in step (6) is sequentially cured, steam stretched and dried.

[0020] Furthermore, the calcination treatment in step (1) is carried out at a temperature of 1200 to 1300° C. and for a time of 4 to 6 minutes.

[0021] By adopting the above technical means, the expanded perlite is calcined to make the expanded perlite expand, reduce its water absorption, and improve its filling effect.

[0022] Furthermore, the energy of the electron beam irradiation treatment in step (2) is 4 to 6 MeV, and the dosage is 1 to 5 kGy.

[0023] By adopting the above technical scheme, the expanded perlite and sepiolite are placed in a bead mill in a suitable proportion for grinding. Kinetic energy is generated during grinding and absorbed by the mixture. At the same time, when the mixture is irradiated by a high-energy electron beam, the energy of the incident electron beam radiation is lost and released to the atoms in the impacted molecules. The atoms are excited and a certain amount of active free radicals are formed on the molecular chain skeleton, which improves the surface activity and promotes uniform crushing.

[0024] Furthermore, during the pulverizing process in step (3), the temperature inside the pulverizer is controlled to be -150 to -130°C.

[0025] By adopting the above technical scheme, the obtained mixed powder is placed in a cryogenic pulverizer pre-cooled with liquid nitrogen for pulverization. The mixed powder structure is homogenized and refined to improve the wear resistance, toughness and other properties of the processed raw materials. At the same time, pulverization under cryogenic conditions can prevent the occurrence of agglomeration of the two raw materials.

[0026] Furthermore, the components and corresponding weight percentages in the treatment solution described in step (4) are: 1-1.4% coumarin, 2-3% quercetin, 0.9-1.5% sodium artesunate, 0.7-0.9% germacrene, 1-1.8% α-bisabolol, 3-5% tartaric acid, and the balance is pure water. The soaking treatment time is 1-2 hours.

[0027] By adopting the above technical solution, the mixed powder obtained after deep freezing treatment is immersed in the treatment liquid for soaking. The mixed powder will quickly absorb the treatment liquid, and the effective ingredients in the treatment liquid will quickly enter the mixed powder along with the water. During drying, the water will evaporate, and the effective ingredients will remain in the mixed powder, giving the mixed powder anti-mildew and antibacterial properties.

[0028] Furthermore, the components and corresponding weight percentages of the fumigation liquid in step (6) are: 5-6% of Artemisia annua ethanol extract, 6-9% of chamomile ethanol extract, 3-5% of dandelion ethanol extract, and the balance is anhydrous ethanol. The fumigation treatment time is 2-4 hours.

[0029] By adopting the above technical scheme, the obtained mixed powder is placed together with natural plant fiber, soybean lecithin and deionized water in a spinning tank for spinning treatment, and then the obtained monofilament is fumigated. The volatile components in the fumigation liquid will act on the monofilament as the fumigation liquid evaporates, further improving the mildew and antibacterial properties of the monofilament. In addition, during the fumigation process, due to the presence of the special mixed powder, the monofilament will be promoted to absorb the volatile components, enhance the fumigation effect of the fumigation liquid, and will not affect the mechanical strength of the finished product.

[0030] Compared with the prior art, the present invention has the following advantages:

[0031] The present application provides a method for preparing a mildew-proof fishing net line. By adding a special mixed powder component during the spinning process, the mildew-proof and antibacterial properties of the fishing net line can be significantly improved, and the physical and chemical properties of the monofilament of the fishing net line can be improved, and its wear resistance and toughness can be improved. Therefore, it can be ensured that the monofilament is further fumigated without damaging the mechanical properties of the monofilament to improve the mildew-proof and antibacterial properties of the fishing net line. In addition, since the mixed powder in the present application has undergone an immersion improvement treatment, when it is used in the processing of the fishing net line, the fishing net line can have a long-lasting and effective mildew-proof and antibacterial property.
