Polypropylene multifilament yarn (PP Yarn) 900D, 1200D

Polypropylene multifilament yarn is appreciated for its high mechanical strength, rigidity, inflexibility compared to PE, and is not stretched, so it is made into yarn. PP yarn has transparent color and high surface gloss, so the printing ability is high and clear. It is resistant to temperatures up to over 100 degrees Celsius and is impervious to oxygen, water vapor, grease and many other gases.
Nam Phat Plastic is the company that produces 900d and 1200d PP yarns used in many applications such as sewing packaging  Besides, it is also used to make window brushes, packaging sewing threads, nets, safety belts. whole....

3. Production method of  polypropylene multifilament yarn PP (yarn 900 D and 1200 D)

In fact, to be able to produce PP yarn is not an easy thing and any unit can do it. Because the production needs to have many unique characteristics by durability, dyeing, lubricating process, suitable for many thread sizes from rudimentary to smooth.
And to be able to create PP yarn, it requires researchers to invest a lot in order to have a simple but highly effective production method. Currently, in the world, the most commonly used industrial sewing method is applied:
- Method 1: To produce PP yarn, the first thing to do is to spin yarn from polyester yarn by rudimentary yarn tubes. Next, it will wrap around polyester filaments to help form corespun yarn. This process also requires the incorporation of short fibers. After spinning, this PP yarn will be wet treated, dyed to create a complete PP yarn.
- The second method: It is a method using cotton spinning technology. From the cotton bales containing many mixed impurities, we need to clean away the impurities and make the cotton become slivers. Then, from these sliver yarns, they need to be treated roughly, combing the cotton fibers to pull them into cotton fibers.
Then they will be sewn together to form perfect industrial sewing threads. But note that all these stages require going through with the help of machines because it is quite complicated.
Besides the two methods mentioned above, at present, the production of PP yarn is still many other methods applied by many manufacturers. However, the two methods mentioned above are the most commonly used in production facilities.
At the same time, the production process of PP 900D and 1200D PP yarn:
● Step 1: Raw materials.
● Step 2: Rotate.
● Step 3: Silverization.
● Step 4: Spin the yarn.
● Step 5: Single coil.
● Step 6: Perform duplication.
● Step 7: Twist the wire.
● Step 8: Form a double coil.
● Step 9: Set heat or add in silicone oil.
● Step 10: Form a slow coil.
● Step 11: Finish, check and pack the finished product.
