Problems solved by technology

[0004] For example, recycled polyester staple fiber uses polyester fabric, waste polyester bottle flakes, spinning waste, foam material, and pulp as raw materials. After processing, polyester staple fibers of different lengths are formed, which belongs to the full utilization of renewable resources. Because of the cost Low and has a broad market, but the strength of recycled polyester is weaker than that of polyester, which leads to restrictions in marketing, making it difficult for renewable resources to meet the market's demand for raw material strength. Therefore, there is still room for improvement

Abstract

The invention relates to the field of textiles, and particularly discloses a production process of antibacterial regenerated polyester staple fibers. The production process of the antibacterial regenerated polyester staple fibers comprises the following steps: 1, drying is conducted, specifically, polyester bottle flakes are dried; 2, spinning is conducted, specifically, the dried polyester bottleflakes are heated into a melt, the melt is subjected to spinning and cooling to obtain tows; 3, oiling is conducted, specifically, an oiling agent is added into the tows, and balancing is conducted to obtain nascent fibers; 4, post-spinning is conducted, specifically, the nascent fibers are stretched to obtain a primary finished product; 5, shaping is conducted, specifically, the primary finishedproduct is died and shaped to obtain the antibacterial regenerated polyester staple fibers; and the oiling agent in the step 3 is prepared from the components: 400-530 parts of water, 8-13 parts of polyoxyethylene fatty alcohol ether, 1.5-2 parts of potassium hexadecyl phosphate and 2-3 parts of hexadecyl benzyl dimethyl ammonium chloride. The production process of the antibacterial regenerated polyester staple fibers has the advantages that the antibacterial property and the flame retardance are maintained, and meanwhile, the breaking strength is excellent.

Description

technical field [0001] The application relates to the textile field, more specifically, it relates to a production process of antibacterial regenerated polyester staple fiber and the production process thereof. Background technique [0002] In recent years, the annual consumption of textile raw materials in my country has reached more than 40 million tons, and it is predicted that if no new oil fields are found, the oil resources as the main raw material for synthetic fibers will be exhausted around 2050, and my country's dependence on crude oil imports is high. , how to reduce the dependence on fossil resources has become a very prominent practical problem, and with the serious problem of grain and cotton in our country, natural fiber resources are limited, and the expansion of population has increased the demand for fiber, and the shortage of textile raw materials has become more prominent . [0003] At present, the annual stock of discarded polyester bottles in my country ...
