Filed: 1932-03-24
Abstract: Cellulose is acetylated in the presence of a non-solvent and sulphur dioxide, using perchloric acid as catalyst.  The temperature is kept below about 40 DEG  C.  Instead of perchloric acid itself there may be used its salts with weak bases, e.g. magnesium perchlorate, or zinc perchlorate, or its salts together with free acids.  In examples, cotton linters pretreated with glacial acetic acid are acetylated in a bath comprising (1) acetic anhydride, toluene, sulphur dioxide, and perchloric acid, (2) acetic anhydride, toluene, sulphur dioxide, and zinc perchlorate, and (3) acetic anhydride, benzene, sulphur dioxide, sodium perchlorate and phosphoric acid.  As catalyst there may also be used a mixture of lithium perchlorate and phosphoric acid.  The fibrous cellulose triacetates, if desired, after converting to an acetone soluble form, e.g. by the process of Specification 355,419, may be employed in the production of artificial silk, films, foils, insulating materials, plastic masses, lacquers, or the like.

Patent GB-449106-A (GB)
Title: Improvements in or relating to the treatment of textile fabrics containing organic derivatives of cellulose
IPC: D06M13/144
Filed: 1935-03-21
Abstract: A method of stiffening fabrics containing organic derivatives of cellulose comprises treating such a fabric with a diluted solvent for the organic derivative of cellulose and subjecting the fabric to uniform pressure while it contains the solvent, so that the filaments in the yarns of the fabric are tacked together but maintain substantially their original shape.  Heat and pressure may be applied to the fabric after the diluted solvent by lightly calendering it or by passing it through a Palmer finishing machine.  If low boiling solvents are employed they are completely volatilized from the fabric which is accordingly resistant to distortion after treatment while high boiling solvents are not completely removed and produce a fabric which may be distorted by local pressure.  The fabric may consist wholly of an organic derivative cellulose, or other materials may also be incorporated therein.  They may be formed by weaving, knitting, knotting or netting of yarns, and may contain pigments, filling materials, dyes, or lakes, fire retardants, plasticizers or lubricants.  The diluted solvent may be applied by spraying, by passing the fabric through a dilute solution or suspension of the solvent, or through solvent vapours.  Preferably, it is applied by padding with nip rollers, belts or other furnishing devices wetted with the solvent solution.  Examples of suitable solvents are acetone, acetone and ethyl or methyl alcohol, chloroform, ethylene dichloride, ethylene dichloride or methyl chloride mixed with ethyl or methyl alcohol, or diacetone alcohol, and of suitable diluents are water, carbon tetrachloride, or benzene.  In an example, a cellulose acetate voile fabric is padded direct with a solution containing 10 litres of diacetone alcohol dissolved in 90 litres of carbon tetrachloride.  The fabric is then treated in a Palmer finishing machine heated to 100-110 DEG  C.  An organdic is produced which retains its stiffness permanently and is only slightly inclined to stretch.  By using a slightly higher temperature or a lower boiling solvent, such as acetone in water, a fabric is obtained that is not subjected to distortions even with localized heavy stresses.  If desired, a volatile diluent, e.g. carbon tetrachloride may be removed in an aspirating hot-air chamber prior to calendering or treatment in the Palmer finishing machine. The diluent and solvent liquids may be recovered.  The fabric may be dyed prior to or after the stiffening.
