Abstract

The invention relates to a colored polyester (PET) industrial yarn of a safety belt and a preparation method thereof. The colored PET industrial yarn of the safety belt is prepared by the steps of: adding color master batches into high-viscosity PET chips which are used as raw materials, carrying out melt spinning, adding a proper amount of spinning oil, and then carry out stretching and winding, wherein for a formula, the colored PET industrial yarn of the safety belt comprises the following components in parts by weight: 100 parts of Hailide HLD301 high-viscosity PET, 1-3 parts of Dainippon Ink BK270 color master batch, and 0.2-0.8 part of Sanyo 951 spinning oil. The preparation method comprises the steps of solid-phase polymerization, drying, blending, melting, metering, cooling and forming, oiling, stretching and winding. The product of the colored PET industrial yarn of the safety belt has the breaking strength reaching more than 7.4CN / dtex, has the characteristics of good wear resistance, uniform color, fewer broken filaments and the like, can be applied to the field of safety belts, and has the advantages of greatly improving the manufacture rate of woven belts and improving the quality of the safety belts.

Description

technical field [0001] The invention belongs to the technical field of polymer fiber production, and in particular relates to a colored safety belt polyester industrial yarn and a preparation method thereof. Background technique [0002] With the continuous development of the automobile industry, polyester industrial yarn has been widely used in the automobile seat belt industry. However, due to the molecular structure of PET itself, it is not easy to be dyed, and it is easy to cause defects such as colored spots and color printing on the belt surface. In addition, the investment in dyeing equipment is large, and it will pollute the environment to a certain extent. Therefore, some high-end customers in the world hope to directly weave seat belts with colored silk without affecting the strength and surface wool, so as to greatly improve the quality of seat belts and save production costs. Contents of the invention [0003] In order to overcome the deficiencies in the prior...
