Knowledge of dyeing factory finalizing

One, nylon cloth

 

1. Setting temperature :160℃-180℃; speed: 20M-25M/ min.

 

2, finalize the design temperature discretion is very big to color change, especially purple, pink orchid, so want to pay attention to do after and before the same color.

 

3, polyamide fabric thickness shrinkage rate is different.

 

4, nylon fabric shape easily hook yarn, if the shape appears a head hook yarn, immediately stop, check the head end, bellow, roller, sand paper polishing, or mat. (e.g. Silk hosiery, mesh)

 

Two, polyester cloth stereotypes

 

1. Shaping temperature: 170℃-200℃, speed: 20M-28M/ min

 

2, polyester design temperature generally does not change, but the bright red dye sublimation fastness is not good, after finishing the case will leave dye, can not immediately do light color, can only do black, can also use waste cloth more than a few times, to do light color.

 

3, polyester frame fabric shrinkage rate is very large, such as the customer requirements of good elasticity, shrinkage rate is small, feel good, must be predestined to die, pay special attention to black and white. Red and white flowers, due to the dye sublimation fastness is not good, the product must be low temperature finalize the design, such as high temperature will be seriously sticky products.

 

4, polyester bo bi cloth shaping, to pay attention to the cloth in the edge thickness, temperature control, not too high, machine speed adjustment, two times pull. The width of the door is about 6-8 inches less than the finished product, and the weight of gram is about 100g. The second time is 5-10 degrees lower than the **** time temperature, door width, gram weight according to the requirements.

 

Three, cotton rayon

 

1. Shaping temperature: 160℃-190℃, speed: 20M-30M/ min

 

2, if the cotton cloth is dyed with direct material, the cool and hot color of the grey cloth changes greatly, the color must wait until the grey cloth completely cooled, the active material changes little.

 

3, human silk high temperature easy aging, burning the embryo cloth easy hook yarn, pull broken.

 

4, cotton shrinkage rate is very large, finalize the design, into the cloth tension to reduce, press the pressure of the car to increase, dry the cloth, hot air fan to ****, machine speed is slow, can reduce shrinkage rate, if the customer requirements are high, will shrink test.

 

5, if the customer requires the cloth not twisted pattern, must twill finalize the design.

 

Four, the silk finalize the design

 

1, the setting temperature 100℃-120℃, speed: 20M-30M/ min

 

2, silk finalize the design hot wind adjustment small, door amplitude shun - ding.

 

3, real silk is more delicate, finalize the design can not get water and sweat, labrador can not too hard.

 

Five. PU rubber.

 

1, imported pulp, high temperature does not change color, 140℃-180℃. Speed 25M-30M// min, large smoke.

 

2. Domestic pulp, easy to change color at high temperature, 140℃-180℃, speed 25M-30M/ min, large smoke.

 

6. Gram weight door frame

 

1, before the set must be measured gram weight and width, such as with the requirements are too far apart, to timely reflect documentary.

 

2, set to pay attention to the weight of the sides can not be too far apart, one cannot be too far from each other.

 

3, finalize the design to pay attention to a piece of cloth before, after whether the same.
