Problems solved by technology

However, the wool-like polyester produced by these methods has a poor wool-like effect, and there is still a certain gap between wool fabrics and wool fabrics in terms of soft touch.

Embodiment 1

[0009] A method for preparing wool-like polyester yarn of the present invention, which comprises: polyester sea-island yarn POY as the first raw material yarn A, a conventional polyester POY as the second raw material yarn B, two bundles of yarns A and B Lead out from the original wire rack, pass through the first double cutter 1, the first micro-moving wire guide 2, the first wire feeding roller 3, and enter the first hot box 4, where the wires in the first hot box 4 The strip undergoes stretching, twisting and deformation in a heated state to form a textured yarn, and then guides through the skid guides 5 and 6. After the cooling plate 7 is cooled, it enters the false twister 8 for false twisting, and forms a boiling water shrinkage of less than 6. % foreign fiber or foreign fiber profiled or foreign fiber heterodyed or foreign fiber profiled dyed mixed fiber plied yarn. The two bundles of A and B can be merged at the first micro-moving yarn guide 2, and then enter the first...

Abstract

The invention provides a preparation method of a wool-like polyester thread; ultra-fine denier polyester sea-island POY (pre-oriented yarn) as a raw material yarn and conventional polyester POY are subjected to drafting and false-twisting deformation compounding to form a mixed fiber plied yarn containing foreign fibers having denier per fiber (pdf) less than 0.1 D and boiling water shrinkage lessthan 6%, special-shaped foreign fibers, or special-shaped special-dyed foreign fibers. The mixed fiber plied yarn is then converged with another high-shrinkage polyester FDY with the boiling water shrinkage rate of more than 20%, and the yarns are compounded together through air spray twisting at an interlacing nozzle to form the wool-like polyester yarn containing the ultra-fine denier fibers with differential shrinkage foreign fibers, profiled differential shrinkage foreign fibers, special-dyed differential shrinkage foreign fibers, or profiled special-dyed differential shrinkage foreign fibers. After weaving, alkali decrement fiber opening and after-finishing of the thread, the ultra-fine denier yarns and the low shrinkage yarns float on the surface of tows in fine natural curling state, so that a prepared fabric is very soft and fine to touch, is full and stiff, and has good resilience. The fabric is lightly sanded, so that a good wool-like effect is achieved.

Description

technical field [0001] The invention relates to the textile field, in particular to a wool-like polyester thread and a preparation method thereof. Background technique [0002] Wool-like polyester filament products are now common in the market. The conventional preparation method is to combine polyester filaments with different properties (cationic dyeability, color, special-shaped cross-section, different shrinkage, different single-filament deniers but the smallest) according to the requirements of the fabric. The fineness of the single filament is greater than 0.3D, etc.), through the jointing of the network machine or through the deformation treatment of the false twister or the air texturing machine, to prepare the blended yarn to obtain the style of the woolen fabric, and also to combine FDY and POY in the spinning process Or compound FDY with different properties to produce three different polyester wool-like filaments with different shapes and different shrinkages in...
