Abstract

This invention relates to a polymer composition containing at least one polymer and at least one agent, formed bodies having such a polymer composition, the use of the formed bodies and polymer compositions, and corresponding threads, nonwoven materials, clothing articles, and medical aids.

First claim

The invention claimed is:

1. A thread or textile surface comprising fibers, wherein the fibers comprise a polymer composition, said polymer composition comprising a polymer; at least one agent selected from the group consisting of petrolatum, an oil or a fat, wherein the oil or the fat contains at least 25 wt % oleic acid, a non-saponifiable lipid from an oil, wherein the oil contains at least 25 wt % oleic acid, and mixtures thereof; and another agent selected from the group consisting of dicaprylyl carbonate, cetyl isononanoate, isopropyl isostearate, isostearyl isostearate, isopropyl palmitate, and mixtures thereof.

2. The thread or textile surface according to claim 1 , wherein the at least one agent selected is from the group consisting of petrolatum, the oil, the non-saponifiable lipid from an oil, and mixtures thereof.

3. The thread or textile surface according to claim 1 , wherein the polymer is a biopolymer.

4. The thread or textile surface according to claim 3 , wherein the polymer is selected from the group consisting of cellulose, modified cellulose, viscose, polylactides, modifications thereof, derivatives thereof, and mixtures thereof.

5. The thread or textile surface according to claim 1 , wherein the at least one agent is petrolatum.

6. The thread or textile surface according to claim 1 , wherein the polymer composition contains petrolatum and the oil that contains at least 25 wt % oleic acid.

7. The thread or textile surface according to claim 1 , wherein the oil contains at least 35 wt % oleic acid, at least 20 wt % palmitic acid, at least 3 wt % palmitoleic acid, at least 5 wt % linoleic acid, at least 5 wt % stearic acid and at least 0.5 wt % cis-9-octadecenoic acid.

8. The thread or textile surface according to claim 1 , wherein the oil is manila oil, olive oil, and/or rapeseed oil.

9. The thread or textile surface according to claim 8 , wherein the rapeseed oil is canola oil.

10. The thread or textile surface according to claim 1 , wherein the polymer composition contains the non-saponifiable lipid.

11. The thread or textile surface according to claim 1 , wherein the polymer composition contains shea butter.

12. The thread or textile surface according to claim 1 , wherein the polymer composition contains petrolatum and the fat that contains at least 25 wt % oleic acid.

13. The thread or textile surface according to claim 12 , wherein the polymer composition contains petrolatum and shea butter.

14. The thread or textile surface according to claim 1 , wherein the at least one agent serves as a skin penetration enhancer.

15. The thread or textile surface according to claim 1 , wherein the at least one agent is an occlusive agent.

16. The thread or textile surface according to claim 1 , wherein the fibers are staple fibers, monofilaments, multifilaments, or continuous multifilaments.

17. The textile surface according to claim 1 , wherein the fibers are present in the form of thread, or wherein the textile surface is a nonwoven material or a felt.

18. The textile surface according to claim 1 , wherein the textile surface is a knitted fabric, a mesh fabric, or a woven fabric.

19. A clothing article, sports aid, or medical aid containing the thread or textile surface according to claim 1 or containing fibers, wherein the fibers comprise a polymer composition comprising a polymer; at least one agent selected from the group consisting of petrolatum, an oil or a fat, wherein the oil or the fat contains at least 25 wt % oleic acid, a non-saponifiable lipid from an oil, wherein the oil contains at least 25 wt % oleic acid, and mixtures thereof; and another agent selected from the group consisting of dicaprylyl carbonate, cetyl isononanoate, isopropyl isostearate, isostearyl isostearate, isopropyl palmitate, and mixtures thereof.

20. The clothing article or sports aid according to claim 19 , wherein the clothing article or sports aid is a jersey, sports pants, underpants, an undershirt, or a stocking.

21. The medical aid according to claim 19 , wherein the medical aid is a bandage or a compression stocking.

22. The thread or textile surface of claim 1 , wherein the at least one agent and the another agent are present as micro-inclusions in the polymer composition.
