Embodiment 1
[0014] The present embodiment——the preparation process of dazzling and charming visual effect coated fabric, comprises the following steps:
[0015] The polyester fabric with a fabric density of 190T is selected, and the pretreatment process is as follows: one (caustic soda 2g / L, temperature 80°C), two (209 detergent 4g / L, temperature 80°C), three (penetrant JFC 2g / L, temperature 95°C), four steps (penetrating agent JFC 2g / L, caustic soda 2g / L, temperature 95°C), five steps (deoiling spirit 0.5g / L, temperature 55°C), and then hot water and cold water washing together.
[0016] The dyeing process adopts the high-temperature and high-pressure jigger dyeing process, which can be kept at 125°C for 3 times, and after dyeing, reduction cleaning is carried out to remove the dyestuffs accumulated on the fiber surface; pre-setting is carried out after dyeing, and the pre-setting process is as follows: The temperature is 185°C, and the vehicle speed is 85m / min; or add a small amount o...
Embodiment 2
[0024] The fabric used in this embodiment is still a polyester fabric with a density of 190T, and its pretreatment, dyeing and printing, and presetting processes are the same as those in Example 1;
[0025] a. Coating the above-mentioned printed polyester pre-shaped fabric, the coating process is divided into two parts:
[0026] (1). Primer: PA transparent glue is used for dry coating of the primer; the formula is: 120kg of PA (2820C) glue, 1.8kg of bridging agent L-75, 0.4kg of anti-sticking agent KC-6500, 20kg of toluene; The coating process is: the amount of primer is 20g / m 2 , the drying temperature increases sequentially with the number of oven sections, that is, the drying temperature increases from 120°C, 130°C, 135°C to 140°C with the oven section by section, and the speed is 60m / min;
[0027] (2). Top coating: use PA (35C) glue mixed with colored pearl powder for dry coating, the top coating glue formula is: PA (35C) glue 42kg, bridging agent L-75 2kg, anti-sticking ...
Embodiment 3
[0030] In this embodiment, the selected fabric is still a polyester fabric with a density of 190T, and its pretreatment, dyeing, and presetting processes are the same as in Example 1.
[0031] a. The above-mentioned dyed polyester pre-shaped fabric is coated, and the coating process is divided into two parts:
[0032] (2). Primer: PA transparent glue is used for dry coating of the primer; the formula is: PA (16+20C) 120kg, bridging agent L-751.8kg, anti-sticking agent KC-6500.4kg, toluene 20kg; The coating process is: the amount of primer is 20g / m 2 , the drying temperature increases sequentially with the number of oven sections, that is, the drying temperature increases from 120°C, 130°C, 135°C to 140°C with the oven section by section, and the speed is 60m / min;
[0033] (2). Top coating: use PA (20C) glue mixed with colored pearl powder for dry coating. The top coating formula is: PA (20C) glue 42kg, bridging agent L-75 1.8kg, anti-adhesive agent KC-650 1kg, toluene 8kg, m...
