Abstract

The invention relates to a high-strength wicking-resistance polyester industrial yarn and preparation method thereof. The high-strength wicking-resistance polyester industrial yarn is prepared by taking modified polyester viscosity-increasing chips as the raw material, melting, spinning and performing post-treatment; the modified polyester is prepared from polyester and amino fatty acid glycol ester, the amino fatty acid glycol ester is dispersed among molecular chains of the polyester, and the molecular chains of the amino fatty acid glycol ester and the polyester have hydrogen-bonding interaction, so that the relative positions of the molecular chains of the amino fatty acid glycol ester and the polyester are fixed; a wicking-resistance agent comprises perfluoroalkyl methacrylate, non-ternaryfluoroalkyl methacrylate and ternary block copolymer containing ultraviolet resistance groups. The prepared high-strength wicking-resistance polyester industrial yarn has the characteristic of inherent high breaking strength of a high-strength polyester industrial yarn, also has excellent hydrophobic property and ultraviolet aging resistance, can be widely applied to outdoors, and has widely application prospect in the field of high-grade light box advertising cloth, waterproof cloth and fabrics for a swimming pool.

Description

technical field [0001] The invention belongs to the technical field of fiber modification, and relates to a high-strength anti-wicking polyester industrial yarn and a preparation method thereof. Background technique [0002] In recent years, with the development of high-grade light box advertising fabrics, swimming pool fabrics and sunshade fabrics, the market demand and application prospects of anti-wicking polyester industrial yarns have become increasingly broad. Anti-wicking polyester industrial yarn refers to the introduction of -CF on the surface of the fiber 2 The group reduces the surface tension of the fiber and makes the fiber surface difficult to infiltrate, thereby endowing polyester with superior water repellency and oil repellency, and making the fiber surface have good low moisture absorption performance. [0003] The active ingredients of anti-wicking agents are fluorocarbons. Fluorocarbons are surfactants with amphiphilic groups, respectively containing a ...
