Abstract:To solve the problem that the traditional sizing process using polyvinyl alcohol(PVA) slurry pollutes the environment，takes a long time and consumes large energy，the size mixing protocol of “high-performance modified starch+native starch+additive”，namely the partial gelatinization sizing technology，is researched，the production of cotton fine high-density fabric using the partial gelatinization sizing technology is discussed from slurry formulation，cost and sizing process parameters and operating specifications，and quality indicators，sizing cost and weaving effect of traditional and the partial gelatinization sizing technology are contrasted and analyzed.The practice shows that the partial gelatinization sizing technology has simple mixing formula，no need of high pressure size mixer cooking，and the temperature of size mixer and gelatinizer can be automatically controlled to make the operation of mixing slurry simple.Slurry tank without steam supply reduces energy consumption；using corn starch instead of PVA can reduce the cost obviously，and it is convenient desizing，low carbon and environmental protection，and the weaving efficiency is increased from 89.7% to 91.4%.
