Description

Technical Field

[0001] The invention relates to the technical field of copolyamide extraction, and in particular to a low-melting-point copolyamide continuous extraction device and a use method thereof. Background Art

[0002] Copolyamide, a polyamide produced by copolymerization of multiple dibasic acids with one or more diamines, multiple diamines with one or more dibasic acids, lactam with amino acids, or a mixture of dibasic acids and diamines with lactam. Its repeating units contain multiple amide groups. Copolyamide fibers are soft, breathable, and moisture-absorbing and perspiration-wicking. They are often used in the manufacture of textiles such as clothing, socks, bedding, and ropes. In addition, high-performance fiber-grade copolyamide chips are also used in clothing fabrics, which can meet the needs of wear resistance, lightness, and improved breathability.

[0003] In the existing copolyamide extraction, the reagents are merely added and stirred. During the extraction process, it is impossible to quickly stir and mix and monitor the temperature changes in real time. The reagents used for extraction cannot be stored within a suitable temperature range to ensure that their performance is not affected. The value of the added reagents cannot be accurately controlled to ensure the correct mixing ratio. It is impossible to quickly detect whether the mixed reagent ratio is correct, and reducing the mixed reagent ratio cannot effectively extract. The liquid coming out after extraction cannot be quickly tested to determine whether re-extraction is needed, and the equipment cannot be quickly cleaned. Therefore, the present application provides a low-melting-point copolyamide continuous extraction device and a method for use to meet the needs. Summary of the invention
