Problems solved by technology

[0011] The core of this three-dimensional crimped hollow fiber preparation process is the use of an asymmetric cooling method, which produces an uneven cooling effect on the fiber. This solution saves equipment investment and the process is relatively simple, but the density of the tow from the spinneret Not one, after the asymmetric cooling process, the coiling performance will be affected, and the final coiling performance and fluffy performance of the fiber will be different

Embodiment 1

[0058] A production line for producing three-dimensional crimped hollow polyester staple fibers, including a pre-spinning production line.

[0059] The pre-spinning production line includes slicer → screening → metal detector → drying → silo → screw extruder → filter → spinning box → metering pump → spinning assembly → spinneret → ring blowing → Preliminary oiling → tunnel → winding oiling machine → tractor → feeding wheel → reciprocating system of silk barrel.

Embodiment 2

[0061] A process for producing three-dimensional crimped hollow polyester staple fiber is as follows: it includes a pre-spinning process.

[0062] The pre-spinning process is as follows:

[0063] 1. For slicing, take two kinds of raw materials that belong to the polyester series, and take the packaged two kinds of raw materials for slicing. The particle size of the slicing needs to be process-required, and it must be uniform so that it meets the processing requirements;

[0064] 2. Screening to remove super-long slices and other impurities that have not been cleaned; to remove super-long slices and other impurities that have not been cleaned, raw materials are cleaned, packaged and sliced ​​by mechanical operations, and there may be uneven slices or other types of plastic that are not cleaned. In the case of cleaning, if the slice is too long, it may be incompletely melted and gelled during the heating and softening process, while the melting point of other types of plastics i...

Abstract

The invention discloses a production line and technology for producing three-dimensional crimp hollow polyester staple fiber. The production line and technology are characterized in that two components are subjected to slicing, screening, metal detecting, drying, feeding, extruding, filtering, spinning, metering and spinning pack applying processes, and the two components are mixed in a spinning pack and then subjected to extrusion, circular blowing, initial oiling, channel passing, oiling, pulling, feeder applying and silk containing barrel reciprocating system applying processes. In this way, raw materials of the different components are treated through the production line by means of different front sections, the two components are mixed in the spinning pack, due to the fact that each monofilament is composed of the different components A and B, and the heat shrinkable properties of the two components are different, the fiber crimp properties are different. The inherent crimp property of the fiber can become more obvious and stable after relaxation heat setting is conducted.

Description

technical field [0001] The invention relates to the field of polyester staple fiber preparation, in particular to a production line for producing three-dimensional crimped hollow polyester staple fibers and a production process thereof. Background technique [0002] Three-dimensional crimped hollow fibers are widely used in the fields of quilts, toys, and non-woven fabrics due to their light weight, good bulkiness, and good warmth retention. [0003] At present, the Chinese patent that publication number is CN101328636A discloses a kind of production technology of three-dimensional crimped hollow fiber, and it comprises: [0004] Spinning process: [0005] Spinning box→metering pump→spinning assembly→semi-open outer ring blown tow cooling→spinning tunnel→oiling→winding machine→traction device→feeding device→since barrel reciprocating device→spun barrel conveying . [0006] Post-processing process: [0007] Stretching barrel→concentrating rack→upper guide frame→bottom gui...
