Abstract

The invention discloses a polyester filament yarn POY finish and a preparation method thereof, and relates to the field of polyester filament yarn finishes. The polyester filament yarn POY finish is prepared from the following components in percentage by weight: 7-12% of base oil, 62-75% of a smoothing agent, 7-12% of an emulsifier, 5-7% of an antistatic agent and the balance of an additive. According to the preparation method, through the specific selection of various functional components and strictly limiting the proportion of the components, the polyester filament yarn POY finish with goodsmoothness, bunching, antistatic performance, excellent heat resistance and fast wettability is prepared, the spinnability is good, the serious problem of coking in the subsequent stretching deformation process and the instability of viscosity temperature and viscosity concentration characteristics in application are effectively solved, the filament broken and end breakage rate is decreased, andunder the same spinning process conditions, the excellent product rate can be significantly improved.

Description

technical field [0001] The invention relates to the field of polyester spinning oil, in particular to a polyester filament POY oil and a preparation method thereof. Background technique [0002] Polyester high-speed spinning and high-speed drawing deformation are typical two-step filament production processes, namely pre-oriented yarn or partially oriented yarn (POY, Pre-Oriented Yarn or Partially Oriented Yarn) and stretched textured yarn (DTY, DrawTexturing Yarn) Divided into two-step combination, referred to as POY-DTY process. During the high-speed spinning process, the polyester filament POY oil is sprayed on the surface of the fiber to improve the textile processing performance of the fiber and avoid spinning abnormal phenomena such as wool, broken ends, white powder, tension fluctuation, and winding during the production process , is an essential additive to ensure smooth spinning. Due to the fast spinning speed, the polyester filament POY oil should not only have t...
