Description

Quick-drying deodorizing antibacterial antistatic polyester fiber and preparation method thereof Technical Field The application relates to the technical field of polyester fiber processing, in particular to a quick-drying deodorizing antibacterial antistatic polyester fiber and a preparation method thereof. Background Polyester knitted fabrics are widely used in the clothing field due to their excellent mechanical properties, good dimensional stability, easy care and other characteristics. However, as hydrophobic synthetic fibers, terylene has compact molecular structure and high crystallinity, which has a plurality of inherent defects of poor hygroscopicity, moisture regain of only about 0.4%, difficult rapid conduction and evaporation of sweat during wearing, easy generation of stuffy and sticky feel, smooth and hydrophobic surface of terylene fiber, providing a proper living environment for microorganisms, easy bacteria breeding and peculiar smell generation, particularly more outstanding problems in sports or high-temperature environments, and poor antistatic performance. In order to solve the problems of poor hygroscopicity, bad smell due to bacteria easily growing and poor antistatic performance of terylene, the terylene knitted fabric is mainly subjected to functional modification in a finishing mode, such as padding moisture-absorbing and sweat-releasing finishing agent to improve hydrophilicity, or applying antibacterial finishing agent to inhibit bacteria growing, or adding antistatic agent to solve the antistatic problem. However, the after-finishing mode has obvious limitations that the functional auxiliary agent is only adhered to the surface of the fiber through physical adsorption or weakening of chemical bond combination, has weak bonding force with a fiber matrix, is easy to fall off after being washed for many times, and has obvious attenuation of functions and poor durability, and in addition, when multiple functions are needed to be realized simultaneously, the multiple functional auxiliary agents are easy to interfere with each other when being used in the same bath, such as charge neutralization among ionic auxiliary agents, competitive adsorption of different auxiliary agents on the surface of the fiber and the like, so that the stable integration of multiple functions is difficult to realize, and only a certain function is focused. With consumer upgrades and advances in textile technology, single function fabrics have been difficult to meet the diverse needs of modern consumers for textile comfort, functionality, and health. High-performance fabric integrating multiple functions of quick drying, deodorization, antibiosis and the like becomes a hot spot direction of market development. However, how to realize efficient and environment-friendly production and processing on the premise of ensuring balanced and durable effects of various functions is still a technical problem to be broken through in the current textile dyeing and finishing industry. Disclosure of Invention The application provides a quick-drying deodorizing antibacterial antistatic polyester fiber and a preparation method thereof, which aim to solve the problem that the existing polyester fiber can not realize multiple functions of quick-drying, deodorizing, antibacterial, antistatic and the like. In a first aspect, the application provides a quick-drying deodorizing antibacterial antistatic polyester fiber, which adopts the following technical scheme: The quick-drying deodorizing antibacterial antistatic polyester fiber is prepared from the following raw materials in parts by weight: 100 parts of PET polyester chip 4-8 Parts of functional master batch Epoxy functional styrene-acrylate oligomer 5-8 parts Silane coupling agent modified montmorillonite 10-20 parts 5-8 Parts of porous silicon dioxide microsphere loaded with hydroxypropyl-beta-cyclodextrin 1-2 Parts of sulfoisophthalic acid metal salt 2-4 Parts of dispersing agent The multifunctional master batch is prepared from the following raw materials in parts by weight: 65-75 parts of PET (polyethylene terephthalate) polyester chips 8-12 Parts of epoxy-terminated hyperbranched polyester 3-5 Parts of sulfonate antistatic agent 2-4 Parts of antibacterial agent. By adopting the technical scheme, the balanced integration of moisture absorption, quick drying, lasting deodorization, efficient antibacterial and antistatic functions is realized, the function retention rate is improved after repeated washing, the defects of single function and poor durability of a post-finishing mode are overcome, and the development requirements of multi-functionalization and high quality of modern textiles are met. The epoxy functional styrene-acrylic ester oligomer is used as a crosslinking bridge, an epoxy group of the epoxy functional styrene-acrylic ester oligomer reacts with a PET end group and a silane coupling agent modified montmorillonite surface functional group to construct a thr
