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
The present invention relates to a kind of preparation method of tubing, be specifically related to the preparation method of the ultra-thin tubing in a kind of high-strength thin footpath.
Background technology
Tubular structural member is the basic building block be widely used in engineering, and the three-dimensional tubulose component of the fabric that adopts high-intensity fiber pbo fiber (monofilament tensile strength 5.2GPa), aramid fiber (monofilament tensile strength 3.0GPa) etc. to make has the advantages such as lightweight, high specific stiffness and specific strength, fatigue durability, corrosion resistance.At present; development along with subjects such as fibrous material, Composites Molding Techniques, Textile Engineering, advanced manufacturing engineerings; using the three-dimensional tubing of high-strength light fibrous material made as a kind of emerging fabrics for industrial use; become a kind of important structural material; can be used for making the products such as various structure repair, conveyance conduit, anti-vibration reinforced, building reinforce, case, thermostable instlated tubular, in a plurality of fields such as chemical, environmental protection, energy conveying, Aero-Space, biotechnology, medical science, application prospect is preferably arranged.But existing tubing ubiquity caliber size is large, thickness of pipe wall, can not bear super-tensile, easily breaks, non-refractory, the problem such as not wear-resisting, can not meet the application demand under some specific conditions.
Summary of the invention
The present invention is for the bore that the existing tubing preparation method of solution can not realize tubing is little, tube wall is thin, and can not meet under special applications the problem to the requirement of the required lightweight of fabric and anti-super-tensile, and then propose the preparation method of the ultra-thin tubing in a kind of high-strength thin footpath.

Step 2, the pbo fiber filament yarn is twisted to processing, as adding, be twisted as 230 sth. made by twisting/rice;
Step 3, weft yarn are not twisted, and weft yarn are wound into to the cop that is applicable to fly-shuttle loom shuttle size;
Step 4, adopt by mutually arranged vertically be the yarn of horizontal and vertical two systems, the woven method of the fabric be interwoven according to certain rule on loom, adopt plain weave construction;
Step 5, start to carry out the braiding of tubing, specifically weave step and be:
Step 5 (one), carry out winder, 50～200 bobbin yarns with certain-length are drawn from bobbin, adopt slitting method to be wound in parallel to each other on the coiled hair on warping machines, forming 50～200 length is the warp beam that 100m～1000m does not wait;
Step 5 (two), by adjusting, in transposing, conversion weft count and the weft width of the method change fabric of lower gear, the weft yarn that weft yarn is single latitude, the density of weft yarn is 10～36.7mm, weft width is at 10～55mm;
Step 5 (three), adjust opening, send latitude, tightening weft speed, keep warp tension not start and fluctuation up and down with beam of a loom and loom simultaneously;
Step 5 (four), woven after, take off fabric.
The invention has the beneficial effects as follows: the present invention adopts thin dawn pbo fiber or aramid fiber as warp thread and weft yarn, by certain weaving process, normalization, size stabilization, serialization, the adaptation of product that can realize the three-dimensional tubing in ultra-thin ultra-fine footpath is good, production efficiency is high, there is anti-strong pulling force, high temperature resistant, fire-retardant, resistance to chemical attack simultaneously, development prospect is preferably arranged.
The accompanying drawing explanation
Fig. 1 is the structural representation of ultra-thin thin diameter tube shape fabric, and Fig. 2 is the ultra-thin thin diameter tube shape of internal diameter 20mm fabric.
The specific embodiment
The specific embodiment one: in conjunction with Fig. 1, present embodiment is described, the preparation method's of the ultra-thin tubing in the described a kind of high-strength thin footpath of present embodiment concrete steps are as follows:
Step 1, select warp thread and the weft yarn of pbo fiber as tubing, the fiber linear density of pbo fiber is 100～300D;
Step 2, the pbo fiber filament yarn is twisted to processing, as adding, be twisted as 230 sth. made by twisting/rice;
Step 3, weft yarn are not twisted, and weft yarn are wound into to the cop that is applicable to fly-shuttle loom shuttle size;
Step 4, adopt by mutually arranged vertically be the yarn of horizontal and vertical two systems, the woven method of the fabric be interwoven according to certain rule on loom, adopt plain weave construction;
Step 5, start to carry out the braiding of tubing, specifically weave step and be:
Step 5 (one), carry out winder, 50～200 bobbin yarns with certain-length are drawn from bobbin, adopt slitting method to be wound in parallel to each other on the coiled hair on warping machines, forming 50～200 length is the warp beam that 100m～1000m does not wait;
Step 5 (two), by adjusting, in transposing, conversion weft count and the weft width of the method change fabric of lower gear, the weft yarn that weft yarn is single latitude, the density of weft yarn is 10～36.7mm, weft width is at 10～55mm;
