specific Embodiment approach 1

[0016] Specific implementation mode one: combine figure 1 To illustrate this embodiment, the specific steps of the preparation method of a high-strength fine-diameter ultra-thin tubular fabric described in this embodiment are as follows:

[0017] Step 1. Select PBO fiber as the warp and weft of the tubular fabric, and the fiber linear density of the PBO fiber is 100-300D;

[0018] Step 2, twisting the PBO fiber filament yarn, as twisting is 230 twists / meter;

[0019] Step 3, the weft yarn is not twisted, and the weft yarn is wound into a yarn suitable for the size of the shuttle of the shuttle loom;

[0020] Step 4, adopting the weaving method of the fabric that is interwoven according to certain rules on the loom by mutually vertically arranged yarns that are horizontal and vertical two systems, that is, adopts plain weave structure;

[0021] Step 5. Start to weave the tubular fabric. The specific weaving steps are:

[0022] Step 5 (1), carry out winding, draw 50~200 bobbi...

specific Embodiment approach 2

[0029] Specific implementation mode two: combination figure 1 To illustrate this embodiment, in step 1 of the method for preparing a high-strength fine-diameter ultra-thin tubular fabric described in this embodiment, 75-200D aramid fibers can be used as the warp and weft of the tubular fabric. Other components and connections are the same as those in the first embodiment.

specific Embodiment approach 3

[0030] Specific implementation mode three: combination figure 1 To illustrate this embodiment, in the third step of the preparation method of a high-strength fine-diameter ultra-thin tubular fabric described in this embodiment, a rapier loom without a shuttle loom is used to weave the tubular fabric, and the yarn needs to be wound to prepare the weft yarn into the bobbin required by the shuttleless loom. In addition to the characteristics of high speed, high degree of automation, and high-efficiency production, the shuttleless loom selected in this embodiment also has a positive weft insertion method, that is, the weft yarn is transferred to the center of the weaving fell without any guiding device, and has strong variety adaptability. , Small footprint, uniform reed width control, there will be a needle hook edge. Other components and connections are the same as those in the first embodiment.

Abstract

The invention relates to a preparation mehtod of a tubular fabric, in particular to a preparation method of a high-strength fine-diameter ultra-thin tubular fabric. The preparation method solves the problem that the existing preparation method of the tubular fabric cannot achieve the tubular fabric with a small caliber and a thin wall and cannot meet requirements for light weight and super-strong tensile force resistance of the fabric in special application. The preparation method particularly comprises steps of: selecting poly-p-phenylenebenzobisthiazole (PBO) fibers with fiber density of 100-300D to serve as warp yarns and weft yarns; conducting twisting treatment on filament yarns of the PBO fibers with twisting of 230 twist / meter; enabling the weft yarns to be free from being twisted, and winding the weft yarns into a appropriate pirn with a shuttle size of a shuttle loom; and adopting yarns of a transverse system and a longitudinal system which are mutually and vertically arranged, interweaving on a weaving machine according to certain rules to form the fabric, i.e. adopting a plain weave structure. The preparation method is used for preparing the fine-diameter ultra-thin tubular fabric.

Description

technical field [0001] The invention relates to a preparation method of a tubular fabric, in particular to a preparation method of a high-strength fine-diameter ultra-thin tubular fabric. Background technique [0002] Tubular structural parts are basic components widely used in engineering. The three-dimensional tubular fabric members made of high-strength fiber PBO fiber (single filament tensile strength 5.2GPa) and aramid fiber (single filament tensile strength 3.0GPa) have light weight Quality, high specific stiffness and specific strength, fatigue resistance, corrosion resistance and other advantages. At present, with the continuous development of fiber materials, composite material forming technology, textile engineering, advanced manufacturing engineering and other disciplines, the three-dimensional tubular fabric made of light-weight and high-strength fiber materials has become an important industrial textile as an emerging industrial textile. Structural materials ca...
