How is nylon yarn made? Let's have a look at Salud Yarn factory.

Nylon is the first synthetic fiber to appear in the world. Its appearance has brought a new look to textiles. Its synthesis is a major breakthrough in the synthetic fiber industry and a very important milestone in polymer chemistry.

To know about the nylon yarn manufacturing process, watch this video. This happened in Salud Yarn Manufacturer.

#1 Twisting Process

Twisting is a process of winding raw silk into a thread of yarn manufacture process. For example, a thread is composed of 24 threads. The 24 threads must be twisted together to make the thread stronger and more delicate. The tighter the thread is wound, the higher the twist. The woven cloth is relatively compact, has a good drape and good fastness. Without twisting, there is no threading, no entanglement between the silk and the silk, the cloth surface is loose, the drape is poor, and the fastness is poor.

#2 Hanking Process

Hank dyeing is the latest yarn dyeing technology that plays an important role in deciding color contrast in knitted fabrics. Hank dyeing is preferred to package dyeing because of the bulkier appearance and handle of hank dyed yarn and is used to dye the most delicate yarns. Hank dyeing has a lower liquor ratio, which enables high-temperature dyeing of yarns.

#3 Dyeing Process

After the hanking process, the DTY becomes loose enough to get dyed, which means every single yarn can be easily dyed. The hanked yarn would be taken into the dyeing tank. Then at a specific temperature, the dye will penetrate into the yarn. Smaller tanks can dye 3 kg. Larger tanks can dye more than 1 ton of yarn at a time.

#4 Winding Process

After the testing process, we have confirmed that the yarn color fastness is of great level. So, we are moving to the next process - winding can be simply understood as making the hanked, dyed yarn the final product - a polyester yarn. As you can see, the loose yarn is winding into a tight one.
