| titleOfInvention | Triangular special-shaped polyester fiber HOY (high oriented yarn) and preparation method thereof |
| abstract | The invention relates to a triangular profiled polyester fiber HOY yarn and a preparation method thereof, wherein a spinning melt comprises saturated fatty acid metal salt and polyester, and the mass ratio of the saturated fatty acid metal salt to the polyester is 0.0005-0.002: 1; the filtered pressure during spinning is 85-125kg/cm 2 The extrusion swelling ratio of the spinning melt is 1.20-1.32; the saturated fatty acid metal salt is a metal salt having 12 to 22 carbon atoms, a melting point of 100-180 ℃ and a dynamic viscosity of 1Pa & s or less. According to the invention, the saturated fatty acid metal salt is added into the spinning melt, which is equivalent to adding the lubricant, so that the post-filtration pressure during spinning is effectively reduced, the outlet expansion is effectively reduced, and the product has a good shape-preserving effect; meanwhile, the metal salt of saturated fatty acid can also be used as a nucleating agent, so that the solidification speed of the fiber is increased, and the shape-keeping effect of the fiber is further improved. |
