Problems solved by technology

At present, there are many technical difficulties in the development of nylon wool-like yarn. The patent CN108728973A discloses a production method of wool-like nylon fiber. Nylon 6 POY yarn is used as the raw silk, which is stretched and deformed, and is not stretched and heated. The nylon 66POY yarn is plied at the network nozzle to form a plied yarn until it is wound into shape
The nylon wool-like yarn processed by this method has poor wool-like effect, and does not have crystal fine luster, and cannot reflect the luster of natural fur

Embodiment 1

[0033] A preparation method of nylon wool-like yarn with fine crystal luster, comprising the following steps:

[0034] (1) Put the dried raw PA6 chips (moisture content ≤ 50ppm) into the silo under nitrogen protection, melt through the screw extruder and accurately metered by the metering pump, and then enter the spinning assembly to set The pressure is 11MPa, and the thin stream of melt is sprayed out through the straight spinneret hole of the spinneret, and the thin stream of melt is cooled by side blowing to form curled primary fibers.

[0035] The melting temperature of the melt is controlled between 252-257°C. The inline spinneret holes 2 are evenly distributed in a circular shape on the spinneret 1, the number of inline spinneret holes is 8, and the aspect ratio of the inline spinneret holes is 17:1 (see figure 1 ). The blowing direction is parallel to the length direction of the straight spinneret hole, the wind speed is 0.38m / s, the wind temperature is 15°C, and the ...

Abstract

The invention discloses a preparation method of a chinlon wool-like yarn with crystal fine glittering luster. The method comprises the following steps of (1) melting dried raw materials-PA6 chips by a screw extruder, performing accurate metering by a metering pump, entering a spinning assembly, spraying out melt trickles through linear spinneret orifices of a spinneret plate at a set pressure, and cooling the melt trickles by cross air blowing to form curled nascent fibers; (2) oiling the curled nascent fibers through an oil nozzle, enabling tows to sequentially pass through a pre-interlacing device, a first godet GR1, a second godet GR2, an interlacing nozzle of a main interlacing device and a third godet GR3, and finally performing winding and forming to obtain crimped chinlon FDY; and (3) processing the crimped chinlon FDY by a crochet machine to obtain the chinlon wool-like yarn with crystal fine glittering luster. The chinlon wool-like yarn provided by the invention has the luster, touch sense and thermal insulation performance of real wool and real fur, and maintains the wear resistance, weather resistance, easy care and other performances of chemical fibers at the same time.

Description

technical field [0001] The invention relates to the technical field of chemical fiber production, in particular to a method for preparing wool-like nylon yarn with fine crystal luster. Background technique [0002] With the recovery of the European economy, people began to pursue a luxurious life, and the demand for fur clothing was increasing day by day in terms of clothing. As a result, some wild animals were on the verge of extinction, and animal fur resources were becoming increasingly scarce. Some animal protection organizations and related people not only strongly oppose the killing of wild animals, but also oppose the wearing of artificially raised animal fur. Replacing real animal fur with synthetic bionic fur is the current development trend of eco-environmental protection. Imitating the structure and characteristics of natural fibers is also an important direction for chemical fiber product optimization and product development. [0003] In this context, the resea...
