[0016] Will figure 1 The fabric shown in the sequence undergoes blank inspection, unwinding, desizing, pre-setting, dyeing, dehydration, opening, setting, and finished product inspection. in:
[0017] The desizing process is to wet the fabric in hot water at 98°C, and then desizing in the desizing solution with additives. At this time, the temperature is still kept at 98°C. After the temperature drops to 90°C Carry out soaping, wash with hot water when the temperature continues to drop to 70°C, and finally wash with cold water at 40°C. Before the desizing step, add the prepared additives into the chemical tank, stir well and pour into refining In the machine auxiliary tank, the additive process formula is: desizing agent M-1011K (concentration: 10g / L), penetrating agent M-7705, one of M-1038C (concentration: 1g / L) and soda ash ( The concentration is 1g / L); the process conditions are pH=11, and the speed of the refiner is 50m / min.

Abstract
The invention relates to a dyeing and finishing process for fine-denier weft-elastic fabrics. The process comprises the following procedures: inspection of grey fabrics; unrolling; desizing; pre-setting; dyeing; dehydration; scutching; setting; and inspection of finished products. The procedure of dyeing employs a gradual heating mode, and the pH value of dye liquor is 4.5 to 5.5; and in the procedure of setting, the fabrics are placed in a setting agent with a temperature of 170 to 180 DEG C and are set at a speed of 40 to 50 m / min. Through optimization of the dyeing and finishing process for the fabrics, colored spots and color difference of the fabrics hardly occur during dyeing.
Description
technical field [0001] The invention relates to a dyeing and finishing process of fine denier weft elastic fabric (elastic poplin fabric CNT137004), which belongs to the textile field. Background technique [0002] The fine denier weft elastic fabric involved in the present invention is a light, slightly wrinkled elastic spandex fabric with excellent recovery rate. This fabric uses elastic covered yarn containing 20D spandex in the weft direction, and nylon semi-gloss filament in the warp direction, which can eliminate the sense of urgency and cramped feeling of fabrics woven only with spandex. However, due to the difference in structure and performance of nylon and spandex fibers, as well as the fact that the fabric is prone to color patterns and color differences during dyeing, it is necessary to formulate a reasonable and feasible dyeing and finishing process. Contents of the invention [0003] The invention discloses a dyeing and finishing process for fine denier weft...
