Embodiment 1
[0042] The sizing elongation of a pure cotton fabric with 14.6tex warp and 4800 total threads is tested:
[0043] Proceed as follows:
[0044] (1) Intercept unsized warp yarns with a yarn fixed-length intercepting device, the total number of intercepted warp yarns is 4800, and the length of each warp yarn is 200mm. Put all the intercepted warp yarns in a hot-air oven, bake them at 105°C to constant weight, take them out, put them in a glass drier to cool for 15 minutes, and weigh them. The dry mass of the sample warp yarns is W0=12.81g;
[0045] (2) Sizing the warp yarn, intercepting the sizing after the sizing with a yarn fixed-length intercepting device, the total number of sizing yarns is 4800, and the length of each sizing yarn is 200mm, put it in a hot-air oven, at 105 ° C Take it out after down-baking to constant weight, put it into a glass desiccator to cool for 15 minutes and weigh the mass. After weighing, the dry mass of the sample sizing is W1=14.21g;
