Title: High temp.-resistant, inert textile sheet for gas filter - made from temp.-resistant filament, esp. glass fibre, by converting into thread, dip-coating with temp. resistant plastic e.g. PTFE and weaving
Inventor: SCHWAN RUEDIGER DR
IPC: D04H1/42
Filed: 1991-11-15
Abstract: High temp.-resistant inert textile sheets (I) are claimed, based on multifilament textile threads which are resistant to temps. above 300 deg.C., combined into yarn(s) which are then twisted together. The surface of the thread has a plastic coating (A) with temp. resistance above 250 deg.C.. Alternatively, the surface of the yarn, and opt. the thread is coated with (A). Also claimed is a process for producing (I), involving (a) prepn. of multifilament thread from filaments with temp. resistance above 300 deg.C., (b) dip-coating with (A) and (c) converting into (I), pref. by weaving. Pref. filaments consist of glass and/or quartz fibre, and (A) is a fluoroplastic film, esp. PTFE or a TFE copolymer, pref. contg. additives such as active carbon, zeolites, noble metals and/or catalysts. The surface of textile (I) itself is also coated with a further layer of plastic with temp. resistance above 250 deg.C., pref. PTFE etc. as above. (I) is cross-woven fabric. USE/ADVANTAGE - (I) are useful as woven filter sheets for use with hot gas (claimed). Coating the individual threads with PTFE etc. prevents corrosion at the unprotected points of contact between threads (contrast prior-art coated textiles) and gives high-temp. textiles with improved chemical resistance. Applications include filters for removing particles from flue gases and for use in carbon black prodn., etc.

In an example, racemic lactide and epsilon-caprolactone were mixed in a molar ratio of 85:15 and slowly heated to 150 deg. C. Polymerisation was started by the addn. of 0.04 ml tin II-diethyl hexanoate. After heating in an oil bath (20h, 150 deg. C) and cooling, acetic ester was added to 1l and the mass was shaken for 20h. The resulting soln. can be used as a wound spray either with or without antibiotics.
