Effect of Testing Conditions on Fibre-Bundle Tensile Properties Part Ⅱ: the Gauge Length and Elongation Speed in Wool Fibre Bundle Measurement

The testing conditions of a fibre bundle tensile tester (TENSOR) are elongation speed (ES), gauge length (GL), pretension, jaw pressure, environmental temperature and relative humidity, instrument linearity and sensitivity. The effects on fibre-bundle tensile properties at different GL and ES have been discussed in detail and compared with Peirce's theories on the weaklinks and the breaking time effect. The experimental results indicate that the tensile properties of fibre bundles are strongly affected by GL and vary with different GL. The reasonable GL should be 5-15mm rather than 3.2mm for wool bundle measurements. The ES ranging from 20mm/min to 40mm/min is beneficial for obtaining comparatively stable and accurate tensile values, whereas 20 mm/min used in current testing for wool fibre bundles is at the lower limit of the suggested range. For bundle modulus measurement, the sampling interval must be selected appropriately. The new calculation of the sampling interval has been established.     

Synthesis and Characterization of Naphthalenesulfonic Formaldehyde Condensates for Improving the Solubility of C.I.Reactive Blue 19 in Alkali Liquor

The solubility of C.I. reactive blue 19 in aqueous alkali is poor, so it isn＇t used to dye cellulosic fiber in cold pad-batch dyeing. In order to improve the solubility of this dyestuff in alkali liquor, the right dispersants will be needed. A series of condensates are synthesized by changing the synthesis conditions such as the ratio of naphthalenesulfonic （N） to formaldehyde （F）, acidity, and their compositions are confirmed by MS spectrum. It is found that in acidity scope of 20%-24% and the ratio of N to F 1∶0.33, the synthesized condensates can efficiently improve the solubility of C.I. reactive blue 19 in alkali liquor. In addition, the influences of the condensates on the exhaust dyeing and the cold pad-batch dyeing are tested.
