Dyed Spunlace Nonwoven Fabric

What is the traditional dyeing process of spunlace non-woven fabrics and what problems are prone to occur?

At present, there is a certain demand for high color fastness dyed spunlace nonwovens in the international market. The main purpose of this type of product is to make food service wipes, or high-end packaging materials-golf club covers, Christmas gift boxes, environmental protection bags, etc. Someone has tried to use adhesive coloring methods to make this type of product. As a result, It's not ideal. The principle of adhesive coloring is to use the function of the adhesive (mainly acrylic rubber) to uniformly coat the paint (pigment) on the surface of the spunlace cloth to achieve the purpose of coloring. The advantages of this coloring method are still there: ①the processing equipment is very simple, only a set of padding tanks with upper and lower rolls and a set of baking equipment are enough; ②the processing technology is also very simple, spunlace cloth the entire coloring process can be completed by gluing through the padding tank, and then baking and drying in an oven. The production speed is fast. Because of the simple process, the production speed is faster, reaching nearly 20 meters per minute, and the daily output can reach nearly 3 Ton. But the biggest disadvantage of the adhesive coloring is that the color fastness is not good, it is easy to fade, and it is easy to cause the spunlace cloth to feel hard, destroying the spunlace cloth's soft feel, moisture absorption and drape and many other advantages, which cannot be fully utilized. Advantages of spunlace cloth.

Dyed spunlace nonwovens by Weston:

Weston improved the dyeing process of traditional spunlace non-woven fabrics, and developed a high color fastness dyed spunlace fabric with the advantages of high color fastness and soft hand feeling. It provides a high color fastness dyed spunlace nonwoven fabric and Its production process.

Weston's main technical solution: a high color fastness dyeing spunlace nonwoven fabric manufacturing process, the specific process flow is:

①The spunlace cloth is rolled; ②the jig dyeing machine is dyed; ③the dryer is drying; ④the stenter setting machine heat setting; ⑤the spunlace cloth after the stenter setting is rewinded;

Among them, the step of dyeing by jigger dyeing machine adopts high temperature and high pressure dyeing method, and the specific process is: cold water enters the vat, washing (2 passes, 60-70°C)-dyeing (2 passes, 50-70°C)-dyeing ( Channel I, 90-110...)—Dyeing (120-140°C, 6~8 channels), soaping (above 90°C, 2 channels), washing (2 channels, 60-80°C)—washing ( Channel I, room temperature) One out of the vat;

④The heat setting of the stenter setting machine adopts multi-stage stenter setting, and the specific process is: feed the dyed and dried spunlace cloth into the stenter setting machine, and the stenter setting machine stenters the spunlace cloth. The stretch rate of grade tentering does not exceed 25%.

[0007] A high color fastness dyeing spunlace nonwoven fabric, the spunlace nonwoven fabric is produced by the following processes: ① the spunlace fabric is thrown into rolls; ② the jig dyeing machine is dyed; ③ the dryer is drying; ④Heat setting by the stenter setting machine; ⑤Rewind the spunlace after stenter setting;

Among them, the step of dyeing by jigger dyeing machine adopts high temperature and high pressure dyeing method, and the specific process is: cold water enters the vat, washing (2 passes, 60-70°C)-dyeing (2 passes, 50-70°C)-dyeing ( Channel I, 90-110...)—Dyeing (120-140°C, 6~8 channels), soaping (above 90°C, 2 channels), washing (2 channels, 60-80°C)—washing ( Channel I, room temperature) One out of the vat;

④The heat setting of the stenter setting machine adopts multi-stage stenter setting. The specific process is: feed the dyed and dried spunlace cloth into the stenter setting machine, and the stenter setting machine stenters the spunlace cloth. The stretch rate of grade tentering does not exceed 25%.

A high color fastness dyeing spunlace nonwoven fabric manufacturing process, the specific process flow is: ①the spunlace fabric is rolled;

②Jig dyeing machine for dyeing; ③dryer drying; ④Stenter setting machine heat setting will rewind the spunlace fabric after stenter setting;

Among them, the step of dyeing by jigger dyeing machine adopts high temperature and high pressure dyeing method, and the specific process is: cold water enters the vat, washing (2 passes, 60-70°C)-dyeing (2 passes, 50-70°C)-dyeing ( I channel, 90-110...)—dyeing (120-140°C, 6~8 channels), one water washing (2 channels, 60-80°C)—water washing (I channel, room temperature), and one out of the vat;

④The heat setting of the stenter setting machine adopts multi-stage stenter setting. The specific process is: feed the dyed and dried spunlace cloth into the stenter setting machine, and the stenter setting machine stenters the spunlace cloth. The stretch rate of grade tentering does not exceed 25%.

A high color fastness dyeing spunlace nonwoven fabric, which is produced by the following processes: ①the spunlace fabric is rolled; ②Jig dyeing machine is dyed; ③Dryer drying; ④Stentering Heat setting by the setting machine; ⑤ Rewind the spunlace cloth after stenter setting;

Among them ②The step of dyeing by jigger dyeing machine adopts high temperature and high pressure dyeing method, and the specific process is: cold water enters the vat, washing (2 passes, 60-70°C)-dyeing (2 passes, 50-70°C)-dyeing ( I channel, 90-110...)—dyeing (120-140°C, 6~8 channels), one water washing (2 channels, 60-80°C)—water washing (I channel, room temperature), and one out of the vat;
