Abstract
The invention relates to a three-dimensional weaved multi-layer tubular fabric and a production process thereof. The fabric comprises weaved yarns (1) and binding yarns (2), wherein multiple layers of weaved yarns (1) are annularly arranged and are mutually crossed to form openings; and the binding yarns (2) are formed by adopting a knitting technology so as to form coils, and the coils penetrate through the openings formed by the weaved yarns to bind the multiple layers of weaved yarns together, thus the three-dimensional weaved multi-layer tubular fabric is formed. The production process of the tubular fabric integrates a weaving technology and a knitting technology, the production process is novel, and the produced fabric is unique in structure.
Description
Affiliated technical field
The present invention relates to a kind of 3 D weaving multilayer tubular fabric and manufacturing approach thereof, belong to textile product designing technique and production field.This tubing has combined the technical advantage of 3 D weaving technology and knitting, forms integrally-built multilayer tubular fabric, and novel structure has promotion prospect preferably.
Background technology
Tubing is generally as the enhancing body of various pipelines, main at present woven, braiding and the non-woven mode of adopting.Because restriction woven and woven tubular fabric preparation method; The thinner thickness of the tubular material that makes; Require bigger pipeline to adopt tubular nonwoven compound material for pipe thickness, tubular nonwoven compound material adopts the method for stitching or heat pressure adhesive that the butt joint of sheet non-weaving cloth is formed a tubular structure more, and seam crossing is easy to generate bigger stress in use and concentrates; Cause cracking or be out of shape inhomogeneous, sealing that causes tubular nonwoven compound material and barrier performance decline.
Adopt the three-dimensional tubing of weaving production, solved the deficiency of woven tubular fabric and non-woven tubing, when having increased the tubing wall thickness, guaranteed the uniformity and the stability of fabric.But because weaving restriction; The 3 D weaving tubing can't large-scale application, and the mode that this patent adopts weaving and knitting to combine is produced three-dimensional tubing, in conjunction with the characteristics of weaving and knitting; Improve shaping efficiency, also do not had relevant report at present both at home and abroad.
Summary of the invention
The problem that the present invention mainly solves is the 3-dimensional multi-layered tubing of exploitation, and can adjust wall thickness and tube wall density as required, and the flexibility that the reinforcement tubular fabric construction changes, and exploitation relevant device realize producing in batches.
For overcoming the above problems, the present invention combines knitting to strengthen the interlayer performance of tube wall through the tubing of weaving production multilayer, makes tube wall become as a whole, and combines its manufacturing approach design equipment that forms a complete production network.Specific as follows:
1, the present invention moves at multi-layer braided yarn (1) to form on the basis of opening each other; Adopt binding yarn (2) to pass opening each layer knitting yarn is bundled into an integral body; Pipe thickness can be by the number of plies control of knitting yarn, and density can be controlled by the angle that knitting yarn intersects.
2, the present invention adopts braiding to combine knitting technology to accomplish, and eight layers of disk (4) are housed on circular knitting machine, installs 36 on each disk and carries spindle (9), and each disk can rotate on request, and per step anglec of rotation is adjustable, between ± 10-40 °.Knitting yarn (1) forms opening at syringe (6) from carrying after spindle (9) is gone up unwinding; Bundled yarn (2) gets into opening and bundlees effect under the effect of crochet hook (10) then; The final tubing that forms is drawn braiding apparatus with tubing at last under the effect of draw-gear (8).
3, the present invention is in the braiding process, and all knitting yarns have formed 36 openings according to the arrangement of carrying spindle (9), at opening part a syringe (6) have been installed; The all corresponding crochet hook (10) in the position of each opening, under the effect of crochet hook, bundled yarn passes from opening; Rotation through disk (4) then inweaves bundled yarn in the middle of the opening, and forms new opening; By that analogy, with the tubing that forms multilayer.
The difference of the tubing of the present invention and other types is to adopt weaving, and has combined knitting, the 3-dimensional multi-layered tubing novel structure of formation, and improved the production efficiency of weaving.
Description of drawings
Fig. 1 is the structural representation of 3 D weaving multilayer tubular fabric
Fig. 2 is the former sketch map of 3 D weaving multilayer tubular fabric
The specific embodiment
Describe below in conjunction with the specific embodiment of accompanying drawing 3 D weaving multilayer tubular fabric.
In conjunction with accompanying drawing 1,3 D weaving multilayer tubular fabric comprises knitting yarn (1), bundled yarn (2).Multi-layer braided yarn (1) circular array intersects to form opening each other, and bundled yarn (2) adopts knitting to form coil, in the opening of knitting yarn formation, passes, and multi-layer braided yarn is bundled, and forms 3 D weaving multilayer tubular fabric.
In conjunction with accompanying drawing 2, the former of 3 D weaving multilayer tubular fabric mainly comprises support (3), rotating disk (4), bundled yarn creel (5), syringe (6), opener (7) and draw-gear (8) composition.Braiding is equipped with 7 layers of rotating disk (9) on the chassis, and 36 knitting yarn spindles (9) are housed on every layer of rotating disk, and 36 crochet hooks (10) are evenly distributed on the circumference of syringe (6).
The present invention is in manufacture process, and knitting yarn (1) is gone up unwinding by spindle (9), gets into the inner shaping area of syringe (6), by draw-gear (8) clamping.The rotation of rotating disk (4) makes multi-layer braided yarn intersect at syringe (6) and locates to form opening that in order to make opening clear, opener (7) amplifies the opening that forms; Form stable opening, crochet hook (10) advances opening formation coil with bundled yarn (2) hook then, and then rotating disk (4) rotates; To bundle coil and inweave, and form new opening, draw-gear pulls out cloth fell with the tubing that forms; The rest may be inferred, just formed 3 D weaving multilayer tubular fabric.
The present invention compares with other correlation techniques, and its outstanding advantage is:
(1) the present invention will weave with knitting and combine, and production technology is novel, and structure is unique.
(2) the present invention forms the multilayer tubular fabric, in the thickness that has increased tubing, has strengthened the bonding strength between each layer, avoids splitting.
(3) tube wall layer number of the present invention can be regulated as requested, the knitting yarn adjustable angle that interweaves, and the tube wall controllable density, and motionless layer yarn can be set, form and axially strengthen yarn.
