application of normal temperature and normal pressure ultra - fine dyeable polyester ecdp in household carpet
ecdp yarn as a new type of environmental protection, energy saving, high performance yarn, because of its normal temperature and atmospheric pressure dyeing and dyeing rate of high characteristics, with a variety of yarns in the blended or interwoven has a greater advantage.
ordinary pet yarn has the advantages of high breaking strength and high elastic modulus, moderate resilience, excellent heat setting performance and high heat resistance. because of its tight structure, the lack of molecules in the molecule adsorption of ionic dyes, it is more difficult to dye, need to add high temperature or carrier conditions with disperse dyes, and incomplete chromatography, color is not bright, environmental pollution
ecdp yarn is a new polyester product which can improve the dyeing performance. by adding the third component isophthalic acid-5-sulfonate (sipm) and the fourth component polyethylene glycol (peg) in the polymerization stage, the yarn can be dyed at 100 ° c under normal pressure with a fully chromatographic and bright cationic dye.
characteristics of ultra - fine dyeable polyester ecdp at room temperature and pressure
ecdp yarn is a new type of environmental protection, energy saving, high performance yarn, with cationic dye dyeing not only save a lot of dye, but also eliminates the residual waste treatment. atmospheric pressure dyeing saves high-pressure dyeing equipment investment, does not require high-pressure steam conditions, dyeing temperature from 130 ℃ to 100 ℃. it is estimated that the dyeing and post-treatment phase can save nearly 30% of the energy. in addition, compared with ordinary pet, ecdp yarn has the following advantages:
(1) bright color, high color absorption, deep dye is good.
(2) soft, not only has the ordinary polyester easy to wash, quick-drying, crisp and other advantages, but also to overcome the ordinary polyester easy to play the ball, moisture absorption and anti-static shortcomings.
(3) feel full, strong sense of wool-like.
(4) its blended fabric may have a two-color effect.
application of ultra - fine dyeable polyester ecdp at room temperature and pressure
ecdp yarn with imitation wool, imitation silk and other product performance, in the clothing, home carpets and car accessories, etc. have a good development prospects. because of its normal temperature and pressure can be dyed and high dyeing rate characteristics, with wool, silk, soybean yarn, acetate yarn and ordinary pet, such as intertwined or blended, unique fabric style, is the ideal high-end home carpet fabric.
our company has regular production:
carpet special yarn: 300d / 144f, 300d / 288f, 600d / 144f, 600d / 288f, 600d / 576f, 900d / 432f, 900d / 864f, 1200d / 576f, 1200d / 1152f, 2400d / 1144f, 2400d / 2304f
to sum up:
with the development of science and technology and the continuous improvement of living standards, people on the synthetic yarn variety and performance requirements are getting higher and higher. with the "green low-carbon, energy-saving emission reduction" concept of normal temperature and pressure can be dyed polyester ecdp yarn will continue to get people's favor, has a very good development prospects.
