Benefits of technology

This patented technology uses an ultraviolet (UV) light source for treatments on cotton fibers without damaging them or causing harmful chemical agents like phosgene gas. It also improves whiterness by removing unwanted substances from it before dying out. Additionally, this new technique does away with traditional methods involving harsh acid baths while maintaining good quality control over the fabric' s appearance. Overall, these technical improvements improve the efficiency and effectiveness of producing colored fabrics through UV ray irradiation techniques.

Problems solved by technology

This patented technical solution involves combining different types of fibers together into one single structure called an integrated fabric made up from these materials. These fabrics are stronger at certain levels compared to traditional manmade products like cotton or rayon because their main components (wools) contain amino acid residues - which make them harden over time when exposed to water). To prevent negative effects such as stain caused by cations between adjacent hydrophobic areas, dyestuffs may also be added onto some parts of the garment being treated. By mixing specific chemical compounds along with each type of material separately, the resulting mixed fabric becomes less likely to get damaged due to its own weight and abrasion resistance properties.

Abstract

The invention discloses a dyeing technology for wool/acrylic blended fabric. The dyeing technology for the wool/acrylic blended fabric is implemented by steps of pretreatment, dyeing and color fixation and has the advantages as follows: ultrasonic waves are adopted during pretreatment, compared with conventional pretreatment, the pretreatment is low in treatment temperature, short in time and high in impurity removal rate, whiteness is improved, damage to wool is small due to no addition of a strong alkali agent, and the pretreatment has little environmental pollution and is more environment-friendly with adoption of a non-phosphorus cleaning agent; with the adoption of a one-step one-bath method for dyeing, the heating speed is strictly controlled, the wool is dyed firstly, staining of a cationic dye for the wool is reduced, the dyeing is uniform, and the dye uptake is high; colophony powder as an environment-friendly natural color fixing agent is adopted in the color fixing process, so that environmental pollution is avoided.
