At present, our acetate product specifications have reached more than 20 kinds. The number of monofilament deniers covers 2.5--4.0, and with the recent scheduled spinneret in place, it can soon cover 2.0--8.0.
Combined with the current demand of customers at home and abroad for acetate tow specifications, we will roughly divide acetate tow products into two categories: common tow series and special tow series.

♣ Commonly used tow series:

Serial No. Tow Specification Serial No. 30 Tow Specification
1 2.7Y/35000 5 3.3Y/35000
2 3.0Y/35000 6 3.3Y/39000
3 3.0Y/35000 Type II 7 3.5Y/35000
4 3.0Y/37000 8 4.8Y/35000

♣ Special tow series:

Serial No. Tow Specification Serial No. 30 Tow Specification
1 2.1Y/35000 10 3.0Y/39000
2 2.2Y/34000 11 3.3Y/30000
3 2.4Y/32000 12 3.3Y/37000
4 2.4Y/32000II type 13 3.9Y/31000
5 2.4Y/35000 14 4.1Y/35000
6 2.5Y/30000 15 5.0Y/35000
7 2.7Y/33000 16 5.4Y/33000
8 2.7Y/35000II type 17 5.4Y/35000
9 3.0Y/35000 18 6.0Y/35000

Tow Packing:
♦ The packaging indicates the date of manufacture, product name, product specifications, tow gross weight, tow net weight, tow bag number, moisture-proof and prohibited hook-and-hang and other special requirements for storage, transportation, loading and unloading.
♦ The tow bag is lined with moisture-proof film material that meets the requirements of food hygiene.
♦ The tow pack is packed in high-strength double-layer corrugated cardboard and tied with PET tape.
