Abstract

The invention belongs to the technical field of dyeing and finishing, and especially relates to a CVC knitted fabric dyeing and finishing method. The CVC knitted fabric dyeing and finishing method comprises following steps: dyeing, washing 1, oxygen bleaching, washing 2, washing 3, and setting; wherein in the step of dyeing, bath ratio ranges from 1:8 to 1:10, 0.5 to 1g of a leveling agent is added into each 1L of water, and 0.3 to 0.5g of a pH conditioning agent is added in each 1L of water. In the step of dyeing, a quantified dye is added at a uniform speed, temperature increasing speed is controlled to be 1 DEG C/min, and full level dyeing of two fibers is realized; at different stages, water at different temperature is used for washing, full washing is performed, so that cloth coloring uniformity is ensured; and setting temperature is determined to be 140 DEG C, and setting speed is determined to be 30m/min via repeated experiments, so that the best dyeing effect is obtained.

Description

technical field [0001] The invention relates to a dyeing and finishing technology, in particular to a dyeing and finishing technology of CVC knitted fabric. Background technique [0002] When CVC knitted fabric is dyed polyester, in the prior art, disperse dyes tend to adhere to the cotton thread, resulting in uneven color adhesion and color difference. Not only the color of different batches of fabrics is different, but also different positions of the same batch will have color difference , which seriously affects the dyeing and finishing effect. In addition, when the CVC polyester-cotton cloth is set, the hot air of the setting machine can cause the disperse dye to sublimate in the oven and stick to the fabric again. Therefore, the temperature and speed of setting are also very important for the dyeing effect. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a dyeing and finishing technology for CVC knitted fabr...
