Problems solved by technology

Because traditional polyester does not have hygroscopicity and has poor air permeability, in the field of clothing, in order to improve the hygroscopicity of polyester fabrics, a double-layer structure with inner hydrophobic and outer hygroscopic is generally designed to achieve moisture absorption and quick drying of the fabric. However, the thickness of such polyester fabrics is often greater than that of single-layer polyester fabrics.
Or carry out hydrophobic finishing on the inner layer on the basis of polyester fabric, but the fabric with hydrophobic treatment will not have a long-lasting moisture absorption effect, and the moisture absorption performance will be greatly reduced after repeated friction and washing

Abstract

The invention discloses a manufacturing method of a quick-dry polyester fabric. The manufacturing method comprises the following steps of (1) mixing organic dibasic acid and dihydric alcohol, and then carrying out a condensation polymerization reaction; (2) adding nano-zinc oxide, titanium dioxide and 2-hydroxy-4-n-octyloxybenzophenone into a product obtained after condensation polymerization, performing mixing, and then carrying out the polymerization reaction again, so as to obtain a copolyester melt; (3) enabling the copolyester melt to be subjected to yarn separation, and then spinning profiled polyester yarns with the fineness of 0.8 dtex to 1 dtex through a profiled spinneret plate; and (4) weaving the prepared profiled polyester yarns and cotton fiber yarns to prepare the polyester fabric. The profiled spinneret plate in the step (3) comprises four spinneret orifices which are arranged in a central symmetry manner and are not communicated with one another, and the four spinneret orifices form a four-leaf shape. The moisture absorption performance and the moisture removal performance of the polyester fabric can be improved, so that the polyester fabric has the quick-drying performance.

Description

technical field [0001] The invention relates to the field of polyester production, in particular to a method for making a quick-drying polyester fabric. Background technique [0002] Polyester is the most widely used synthetic fiber variety. Polyester fabrics made of polyester are used in many fields, most commonly in the field of clothing. Because traditional polyester does not have hygroscopicity and has poor air permeability, in the field of clothing, in order to improve the hygroscopicity of polyester fabrics, a double-layer structure with inner hydrophobic and outer hygroscopic is generally designed to achieve moisture absorption and quick drying of the fabric. However, the thickness of such polyester fabrics is often greater than that of single-layer polyester fabrics. Or carry out hydrophobic finishing on the inner layer on the basis of polyester fabric, but the moisture absorption effect of the fabric with hydrophobic treatment is not long-lasting, and the moisture ...
