Method for removing stains from textiles
View Patent ↗A stain removing composition having a mixture of N-methyl pyrrolidinone and at least one solvent from the group consisting of 3 -pentanol, dipropylene glycol monomethyl ether, propylene glycol n-propyl ether, and diethylene glycol monobutyl ether. Preferably the stain removing composition comprises, in percent by weight about 70 - 90 %, N-methyl pyrrolidinone and about 10 - 30 %, in percent by weight, at least one of the solvents from the group described above. In another embodiment, a method of removing a stain from a textile includes the steps of applying the stain removing composition to an area of application. After the composition has been applied to the area of application it is removed with a suction device or other type of absorption device. Water may be applied to the area of application after the composition has been applied to dilute the composition and help in the removal process.
1. A method of removing a stain from a textile comprising the steps of:
applying to an area of application of the textile a composition being prepared by admixing:
about 70-90%, in percent by weight, N-methyl pyrrolidinone; and
about 10-30%, in percent by weight, at least one solvent selected from the group consisting of 3-pentanol, dipropylene glycol monomethyl ether, propylene glycol n-propyl ether, and diethylene glycol monobutyl ether.
2. The method according to claim 1 , further comprising the step of removing the composition from the surface of the textile.
3. The method according to claim 2 , wherein the composition are removed with a suction device.
4. The method according to claim 3 , wherein the suction device is a vacuum.
5. The method according to claim 2 , wherein the composition is removed with an absorption device.
6. The method according to claim 1 , further comprising the steps of:
applying water to the area of application to dilute the composition; and
removing the water and the stain from the area of application.
7. The method according to claim 6 , wherein the water and the composition are removed with a suction device.
8. The method according to claim 6 , wherein the water and the composition are removed with an absorption device.
9. A method of removing a stain from a textile comprising the steps of:
applying to an area of application of the textile a composition being prepared by admixing:
about 70-90%, in percent by weight, N-methyl pyrrolidinone; and
about 10-30%, in percent by weight, at least one solvent selected from the group consisting of dipropylene glycol monomethyl ether, propylene glycol n-propyl ether, and diethylene glycol monobutyl ether.
10. The method according to claim 9 , farther comprising the step of removing the composition from the surface of the textile.
11. The method according to claim 10 , wherein the composition are removed with a suction device.
12. The method according to claim 11 , wherein the suction device is a vacuum.
13. The method according to claim 10 , wherein the composition is removed with an absorption device.
14. The method according to claim 9 , further comprising the steps of:
applying water to the area of application to dilute the composition; and
removing the water and the stain from the area of application.
15. The method according to claim 14 , wherein the water and the composition are removed with a suction device.
16. The method according to claim 14 , wherein the water and the composition are removed with an absorption device.
