Title: Improvements in filters for cigarettes
IPC: A24D3/08
Filed: 1961-03-29
Abstract: In the production of fibres for cigarette filters (see Group VI), polyvinyl alcohol fibres are acetalized in an aqueous formaldehyde solution containing sulphuric acid and sodium sulphate.  Vinyl copolymer fibres containing vinyl alcohol groups may also be used.ALSO:Fibres for cigarette filters are made of polyvinyl alcohol or a vinyl copolymer containing at least 50% vinyl alcohol units, the alcohol groups being at least partly acetalized.  The polyvinyl alcohol fibres are generally obtained as a tow, e.g. of 60,000 deniers or more, by wet spinning, but dry or "semi-melt" processes may be used.  After spinning the fibres are acetalized and may also be subjected to stretching, crimping and cutting. Additives, e.g. perfumes, plasticizers, dyestuffs or pigments, may be incorporated, preferably before spinning.  In one example, a 17% aqueous solution of polyvinyl alcohol is spun into an acid aqueous sodium sulphate solution maintained at 97 DEG  C. to produce filaments of denier 1.5, the filaments grouped to form a tow of 75,000 denier and this tow acetalized in an acidified aqueous formaldehyde solution, rinsed, washed and dried.  A tow may be made up of a mixture of acetalized and non-acetalized fibres.
