Based on the wicking dynamics model of fiber assembly and the melt spinning dynamic model of hollow fiber, the high moisture permeability fiber and blended yarn were optimized, and the hydrophilic hollow microporous modified polyester fiber was developed with hydrophilic polyether as copolymerization modification component. In view of the low strength of hydrophilic hollow microporous modified polyester fiber, easy to break in carding process, short fiber and affect yarn strength, a flexible carding technology was developed.
The large-scale preparation of moisture absorption and heating (winter), moisture permeability and quick drying (spring and summer), moisture permeability and warm (autumn and winter) series of all climate heat moisture comfortable yarn and fabric products blended with microporous modified polyester fiber and cotton, viscose and Lyocell fiber were studied. The design principle of yarn contact comfort was studied, and the high-quality spinning technology of new solvent method cellulose fiber with high efficiency and low consumption was developed, and a series of functionalization was realized The industrialization of cellulose fiber blended yarn with new solvent method has created a new mode of functional yarn design and development.
The project has core intellectual property rights, has formed 80000 compact Siro spinning full climate thermal and wet comfort spinning production line, and completed the technical transformation of 36000 spindle functional yarn intelligent production line.
