Ql-7378 pet down silicon is more elastic, more slippery and more environmentally friendly
When we rethink the design of silicone oil for polyester staple fiber, we hope to focus on the smoothness, elasticity and environmental protection of the production process expected by customers. Finally, we optimized the special molecular structure and emulsification formula of silicone oil, making the silicone oil and superfine polyester staple fiber have better adsorption, the production process is more environmentally friendly, and the down like polyester treated by silicone oil is more elastic and slippery.

Recommended formula for down like products:
Ql-7108 pet down cotton front spinning oil is recommended for front spinning; ql-7378 pet down silicon and ql-1838 high temperature resistant cationic antistatic agent are recommended for rear spinning oil tank; ql-7378 pet down silicon is added with 1% ~ 2% ql-9018 silicone oil crosslinking agent for spraying.
usage method:
1. Oiling in post spinning drawing oil tank: ql-7378 pet down silicon and ql-1838 high temperature resistant cationic antistatic agent are recommended. Ql-7378 pet down silicon concentration should be controlled at about 2%; ql-1838 high temperature resistant cationic antistatic agent is recommended to use 0.5 kg per ton of fiber and spray 2-3 kg out of the oven; the specific concentration is calculated according to the production capacity of the production line.
2. Spray oiling after spinning: spray oiling before or after crimping machine, dilute the measured ql-9018 silicone oil crosslinking agent with 10 times water, add it to ql-7378 pet down silicon, stir for 30 minutes, control the silicone oil concentration at about 3% ～ 5%; adjust according to the production line capacity and final effect.
1) Water quality requirements: conductivity below 10us / cm, hardness below 3mg / L (with CaCO3), pH 6.0-8.0.
2) This silicone oil is used for spinning down fiber. Please test its suitability before using it for other purposes.
3) All chemicals may have adverse effects on the environment and human body. Therefore, all units producing and using chemical substances, including our company, should take preventive measures to prevent environmental pollution and occupational health hazards according to the requirements of environmental protection and occupational health. Pay attention to site ventilation, wearing protective equipment, waste water and waste treatment, etc. refer to the SDS of the product for details.
4) The oil agent will freeze when it is below - 5 ℃. Before use, it will be heated to 20 ~ 30 ℃ and completely dissolved before use, which will not affect the quality.
5) Attention should be paid to the moisture discharge of the oven. If the moisture discharge is not good, it will lead to the decrease of the silicon fastness of the fiber, or even the problem of silicon dropping. In case of the above problems, please improve the moisture discharge amount and discharge more moisture out of the workshop as much as possible.
6) The shelf life of this product is 6 months, avoid direct sunlight, indoor (10 ~ 40 ℃) sealed storage.
