Description
Technical field
The present invention relates to fabrics printing and dyeing technical field more particularly to a kind of methods of Polyester Textiles rapid dyeing.
Background technique
Polyester fiber is due to intensity height, and resilience is good, and high abrasion resistance, good stability of the dimension, wrinkle resistance is excellent, and by
It is widely used in various textiles and garment material.But it is a kind of hard-packed hydrophobic fibre, molecules align is whole
Together, crystal region is more, and polarity is smaller, lacks hydrophily, and expanded level is low in water, and without specific dye radical, causes terylene fine
Dimension can cannot occur in water to be swollen and increase intermolecular gap as cotton fiber, or pass through active group unity with dyestuff
It closes, this brings certain difficulty to dyeing.Current main colouring method is high temperature and high pressure method (120~130 DEG C) and heats
Decoration method (180~220 DEG C), but both methods all has that energy consumption is high or excessively uses water.As people are to textile
The diversified pursuit of energy, blended fabric kind gradually increase, and when terylene and silk, wool, spandex etc. is blended, take high temperature height
Platen press or pad-dry-cure dyeing method, the fiber of the poor heat resistance of blending can then generate damage.For this purpose, many researchers begin one's study and change
The technical method of kind dyeing terylene.
China Patent Publication No. CN103243588B, publication date are on August 14th, 2013, denomination of invention are as follows: one kind is washed
The method of synthetic fibre textile high-temperature pressure dyeing, the invention are mixed using high proportion alcohol organic solvent and a small amount of water and disperse dyes
Dye liquor made of conjunction dyes Polyester Textiles under high-temperature and high-pressure conditions.Its advantage is that dispersion can either be improved preferably
The dispersion performance of dyestuff, and can reduce dyeing difficulty, improve dyeing effect, improves dyeing quality.But dyeing course is in high temperature
It is carried out under the steam of high pressure, damage will cause to the intensity of fiber, and generate non-reversible deformation, overflow dyeing machine bears high temperature for a long time
High pressure does not meet safe and environment-friendly, low-carbon development trend so that machine has certain risk.
China Patent Publication No. CN105672002B, publication date are on June 15th, 2016, denomination of invention are as follows: one kind is washed
The method of synthetic fibre continuous melt dyeing, which is that disperse dyes, performed polymer and auxiliary agent are mixed to composition staining solution, then to terylene
It padded, dried, being baked and washing process, to achieve the purpose that dyeing.Its advantage is that the uniformity of dyeing is good, dyestuff phase
