Abstract

The invention discloses a sizing technology for dope dyed polyester low stretch yarn. The sizing technology includes four work processes including warping, sizing, waxing and warp beam combining. The waxing process is added on the basis of the sizing process, so that smoothness of warp is greatly improved, frictional coefficient of low stretch yarn is reduced, and opening is enabled to be clearer and smoother. During sizing, since the dope dyed polyester low stretch yarn is poor in tensile property, a negative stretching method is utilized to facilitate the improvement of the tensile property of the sized warp, sizing rate is increased at the same time, abrasive resistance of the warp is strengthened, and broken warp is reduced.

Description

【Technical field】 [0001] The invention relates to a sizing process for liquid-dyed polyester low-elastic yarns in the textile industry, in particular to a sizing process for fine-denier liquid-colored polyester low-elastic yarns suitable for water-jet weaving. 【Background technique】 [0002] According to incomplete statistics, the daily discharge of printing and dyeing wastewater in China is 3×10 6 to 4×l0 6 cubic meters, the printing and dyeing industry has become one of the key polluting industries in my country, and the textile printing and dyeing wastewater discharged occupies the sixth place in the national industrial sector's wastewater discharge and the fourth in the COD discharge, seriously affecting the natural ecological environment. The large and medium-sized enterprises in the textile industry will all implement clean production, which will be the only way to go. The dope dyed fiber is directly melt-spun by blending the colorant and the polymer. Since the color...
