Alkali deweighting finishing process of moisture-absorption and quick-drying fabric based on regenerated polyester fibers

Abstract

The invention discloses an alkali deweighting finishing process of a moisture-absorption and quick-drying fabric based on regenerated polyester fibers. The alkali deweighting finishing process comprises the following steps: firstly, adopting a blended fabric prepared from the following raw materials in percentage by weight: 85% of the regenerated polyester fibers and 15% of natural silk; preparing a NaOH solution with the concentration of 15g/L and adding 0.4g/L-0.6g/L dodecyl dimethyl benzyl ammonium chloride cationic surfactant into the NaOH solution; then adopting an electro-thermal constant-temperature water bath kettle and setting the temprature of the water bath kettle to 100 DEG C; then adding the container with the prepared NaOH solution into the water bath kettle; and putting the blended fabric prepared from the raw materials in percentage by weight into the container and carrying out alkali deweighting treatment for 30min. The fabric treated by the alkali deweighting finishing process has minimum strength loss; the surface loss of the fibers in the fabric is less and the strength drop of the fabric is less; and the technical index requirements on moisture-absorption and quick-drying products meeting Chinese standard requirements can be met.

Description

technical field [0001] The invention relates to an alkali weight reduction finishing process of a moisture-absorbing and quick-drying fabric based on regenerated polyester fibers. Background technique [0002] With the continuous consumption of social resources and the aggravation of environmental pollution, more and more people pay attention to the environmental protection society, develop a low-carbon economy, and start to advocate the recycling of waste resources, which can not only protect the environment, but also solve the problem of the shortage of social resources today. status quo. Regenerated polyester fiber is a kind of fiber with recycled PET polyester as the main raw material. The raw material source is mainly waste polyester bottle flakes. Therefore, the fabric developed using recycled polyester fiber as raw material is not only environmentally friendly but also meets the requirements of sustainable development. With the continuous improvement of my country's w...

Problems solved by technology

[0003] Firstly, SEM cross-section observation was carried out on the regenerated polyester fiber, and then the basic properties of the fiber were tested. The experimental results show that the regenerated polyester fiber and ordinary polyester fiber have similar transverse cross-section characteristics, both are solid regular circular cross-section, and the longitudinal direction is a smooth cylinder shape, the moisture regain of the fiber is very low, so the moisture absorption and quick drying of the fiber is poor

The fiber strength is higher but the elongation at break is small, and the initial modulus is high, indicating that the fiber is more rigid and less elastic
