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

Embodiment 1

[0010] The thermal transfer printing process of a moisture-absorbing and quick-drying fabric based on recycled polyester fiber in this embodiment includes the following steps: first, a blended fabric with the following raw materials in weight percentage is adopted: 85% recycled polyester fiber, 15% Tencel; After alkali reduction process, it can make it have dilution and quick-drying performance, and then use digital inkjet cutting machine and manual flat heat transfer machine for fabric heat transfer printing operation. First, connect the digital inkjet cutting machine to the computer and pass The RIP software opens the pattern to be printed, uses the solvent ink in the printer function of the digital inkjet cutting machine to print the pattern onto the special metal foil paper, and uses the cutting function of the digital inkjet cutting machine to cut the printed pattern paper Then, when the temperature of the flat heat transfer machine reaches 200°C, put the pattern paper on t...

Abstract

The invention discloses a thermal transfer printing process for moisture-absorbing and quick-drying fabrics based on regenerated polyester fibers, which comprises the following steps: firstly, a blended fabric of raw materials in the following weight percentages is used: 85% regenerated polyester fibers, 15% tencel; After the alkali reduction process, it has dilution and quick-drying properties, and then uses a digital inkjet cutting machine and a manual flat heat transfer machine for fabric heat transfer printing. The thermal transfer printing fabric of the present invention has the characteristics of fastness to light and washing, strong color fastness, and rich and bright colors, and because the pattern is printed on the paper in advance, it eliminates the shortcomings of inaccurate alignment and defects, so the thermal transfer There are basically no defective products in printing.

Description

Technical field [0001] The invention relates to a heat transfer printing process for moisture-absorbing and quick-drying fabrics based on regenerated polyester fibers. Background technique [0002] With the continuous consumption of social resources and the increasing environmental pollution, more and more people pay attention to the environmental protection society, develop a low-carbon economy, and begin to advocate the recycling of waste resources, which can not only protect the environment, but also solve the current shortage of social resources. status quo. Recycled polyester fiber is a fiber that uses 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 in line with the requirements of sustainable development. With the continuous improvement of my country's waste PET recycling technology, t...
