Rheological Examination of Textile Starch Pastes . In practical application it is known by experience that viscosity of starch pastes is increased by borax and lowered by carbamid. Reasons for these phenomena are not yet fully explained. It was attempted to throw light on the matter by means of appropriate laboratory tests. As chromatography proved, borax respectively carbamid are bound to potato starch during the process of pasting up by physical and not by chemical power, for both borax and carbamid are separated from the starch in the course of chromatography. For measuring the viscosity the rotation viscosimeter has shown many advantages over other viscosimeters. Results of chromatography have given some interesting clues as to the starch complexes, so that much more information may be obtained from further tests. As literature on the subject which is available at present does not prove infomative, it is desirable that the reported results will lead attention of both research workers and experts to this interesting and important matter.
