Method for preventing deposit forming on guide rollers
The invention relates to a method for preventing or reducing deposit forming of superabsorbent material and/or oil onto guide rollers during the process of applying a superabsorbent water-in-oil emulsion onto a yarn wherein the oil is a mixture comprising saturated hydrocarbons, characterized in that the at least 70 wt % of the hydrocarbons have 20 to 32 carbon atoms.
1. A method for preventing or reducing deposit forming of superabsorbent material and/or oil onto guide rollers during the process of applying a superabsorbent water-in-oil emulsion onto a yarn, the oil being a mixture comprising saturated hydrocarbons, wherein at least 70 wt % of the saturated hydrocarbons have 20 to 32 carbon atoms.
2. The method according to claim 1 , wherein at least 75 wt % of the hydrocarbons have 20 to 32 carbon atoms.
3. The method according to claim 1 , wherein at least 79 wt % of the hydrocarbons have 20 to 32 carbon atoms.
4. The method according to claim 1 , wherein the method is further applied on-line to a yarn that is directly obtained from a spinning process.
5. The method according to claim 4 , wherein the yarn speed is at least 220 m/min.
6. The method according to claim 1 , wherein the yarn is an aramid yarn or a glass yarn.
7. The method according to claim 2 , wherein the method is further applied on-line to a yarn that is directly obtained from a spinning process.
8. The method according to claim 3 , wherein the method is further applied on-line to a yarn that is directly obtained from a spinning process.
9. The method according to claim 7 , wherein the yarn speed is at least 220 m/min.
10. The method according to claim 8 , wherein the yarn speed is at least 220 m/min.
11. The method according to claim 2 , wherein the yarn is an aramid yarn or a glass yarn.
12. The method according to claim 3 , wherein the yarn is an aramid yarn or a glass yarn.
13. The method according to claim 4 , wherein the yarn is an aramid yarn or a glass yarn.
14. The method according to claim 7 , wherein the yarn is an aramid yarn or a glass yarn.
15. The method according to claim 8 , wherein the yarn is an aramid yarn or a glass yarn.
16. The method according to claim 5 , wherein the yarn is an aramid yarn or a glass yarn.
17. The method according to claim 9 , wherein the yarn is an aramid yarn or a glass yarn.
18. The method according to claim 10 , wherein the yarn is an aramid yarn or a glass yarn.
