The artificial insemination technology is adopted to improve more than 20 million low-quality down producing goats in the project area, and the down quality of down producing goats raised by vast herdsmen is obviously improved, so that higher economic benefit is obtained.
In 2017, 200kg of high-quality raw cashmere is produced through grading and finishing of the ultra-fine and ultra-long cashmere. The fineness is 13.38 mu m, the straightening length is 61.68mm and the velvet content is 68 percent according to the detection of textile institute of Tianjin university of Industrial science.
In 2017, inner Mongolia Menggong wool industry Limited liability company is put into operation in a technical demonstration park of Arashan-constructed cashmere industry, 0.2385 tons of high-end lint with the fineness of 14.32 microns are combed on the basis of high-quality raw wool production in 2018, the length of a hand row reaches 38.6mm, the length is increased by 20%, the fiber damage rate is reduced by 50%, the impurity content in coarse fibers is reduced by 40%, the short wool rate below 20mm is reduced by 40%, the production efficiency is improved by 40%, the production energy consumption is reduced by 30%, and the yield is improved by 5%. The technical breakthrough of the ultra-fine and ultra-long plush production from laboratory sample production to factory batch production is realized. In 28 days 8 months in 2018, on the second AlLashan high-quality cashmere auction, the group of plush is at the highest bargain price of 102 ten thousand yuan/ton, which creates the precedent of high-quality and high-price cashmere in China and has milestone significance.
The above description is only a preferred embodiment of the present invention, and for those skilled in the art, the present invention should not be limited by the description of the present invention, which should be interpreted as a limitation.
