The specific embodiment

A kind of embodiment based on the symmetric 3 D weaving process of space group

; In Fig. 1～3, this method comprises the steps:

A) as shown in Figure 1, lay last one group of knitting yarn 103 earlier, an end of each knitting yarn 103 is fixed; The other end is free; The free end correspondence of knitting yarn 103 is on one group of orthohexagonal summit, and these orthohexagonal length of sides all equate, and these orthohexagonal corresponding sides are all parallel; All orthohexagonal inscribed circle centers of circle all are on the parallel lines of one group of equidistance, adjacent each regular hexagon of each regular hexagon periphery respectively with the shared summit of this regular hexagon.That is to say, be in a regular hexagon periphery and the regular hexagon adjacent with this regular hexagon all with the shared summit of this regular hexagon.This organizes the orthohexagonal inscribed circle center of circle and also all is in being provided with on the regular hexagon 108 of one group of inscribed circle center of circle coincidence; An orthohexagonal number that is provided with on the regular hexagon is Duoed 6 than with this orthohexagonal number that adjacent inboard of regular hexagon is provided with on the regular hexagon being set; We can know by Fig. 1; Be in the most inboard being provided with and have 12 regular hexagons on the regular hexagon 108, with the most inboard orthohexagonal number that is provided with on the regular hexagon that the adjacent outside of regular hexagon 108 is set be 18, if the most inboard regular hexagon that is provided with is that ground floor is provided with regular hexagon; Corresponding integer 1; And with the most inboard regular hexagon that is provided with that the adjacent outside of regular hexagon 1 is set be that the second layer is provided with regular hexagon, corresponding integer 2, and the like; The orthohexagonal number that the K layer is provided with in positive six distortion just is: 2 (K+2)+2 (K+1)+2K also can draw the orthohexagonal number that adjacent ectonexine is provided with on the regular hexagon thus and differ 6.This digital rule is a kind of objective reality; Satisfy on the parallel lines that the inscribed circle center of circle all is in one group of equidistance at each regular hexagon; Adjacent each regular hexagon of each regular hexagon periphery respectively with the shared summit of this regular hexagon; And this organizes that the orthohexagonal inscribed circle center of circle is in all also that one group of inscribed circle center of circle overlaps when being provided with on the regular hexagon, and this digital rule just exists.Be in the most inboard being provided with in the present embodiment and have 12 regular hexagons on the regular hexagon 108; In other embodiments; Being in the most inboard orthohexagonal number that is provided with on the regular hexagon also can be 18,24 or 30, and this depends on the cavity size that required fabric is inboard.

Being a limit with each orthohexagonal each limit then all can be provided with an equilateral triangle outside correspondence orthohexagonal; All knitting yarns all are on the summit of these equilateral triangles in above-mentioned this group knitting yarn; Some is in the inboard in these equilateral triangles; Three summits that are in inboard equilateral triangle have a knitting yarn respectively, and some equilateral triangle is in the outside, and the equilateral triangle that is in the outside has only on two summits and has knitting yarn; The 3rd summit do not have knitting yarn; That is to say that the equilateral triangle that three summits all are orthohexagonal summits is to be in inboard equilateral triangle, the equilateral triangle that to have only two summits are orthohexagonal summits is the equilateral triangle that is in the outside.On the 3rd summit of the equilateral triangle outside these are in a knitting yarn is set all also.

Above said equilateral triangle can overlap, that is to say, when outwards equilateral triangle being set, having some equilateral triangles and coincide together with different orthohexagonal limits, in fact, be in inboard equilateral triangle and all overlap.

As shown in Figure 2; Axle yarn 104 on all laying in each regular hexagon in diagram; The two ends of each root axle yarn 104 are all fixing, and an end of axle yarn is fixed together with the stiff end of knitting yarn, and the other end of axle yarn is fixed on the plane that the free end of each root knitting yarn belongs to.

B) as shown in Figure 3; Every knitting yarn all is on the summit of above-mentioned equilateral triangle; Three summits crossing these equilateral triangles 105 all can be provided with a circumscribed circle 106; The center of circle of these circumscribed circles 106 all is positioned on one group of parallel lines that are parallel to each other 107, and these parallel lines 107 all are parallel to above-mentioned orthohexagonal corresponding edge.When braiding; Be in three knitting yarns on the same circumscribed circle 120 degree that move in the same way in a circumferential direction; That is to say that one in three knitting yarns moves to an adjacent knitting yarn place in a circumferential direction, this adjacent with it root knitting yarn then moves on to the position at the 3rd knitting yarn place along the direction identical with it; The 3rd knitting yarn is then along moving to the original position that belongs to of first knitting yarn with preceding two identical directions of knitting yarn; When these three knitting yarn motions, the three can move simultaneously, also can move during difference.Motion in the same way on the circumscribed circle is intermittently carried out always, that is to say, has carried out once can stopping a period of time after the motion in the same way on the circumscribed circle and has moved next time again, and in whole braiding process, the homodromous direction on circumscribed circle is constant always.The center of circle is positioned on the circumscribed circle on two adjacent parallel lines that motion hockets and the direction of motion is opposite; That is to say; Motion on circumscribed circle can stop a period of time after finishing; Stop during this period of time in, the motion that is on the circumscribed circle on the parallel lines adjacent with the parallel lines at place, the center of circle of this circumscribed circle begins to carry out, and after all knitting yarns all move once, promptly weaves one deck fabric.Since each root axle yarn in motion process, all have belong on two circumscribed circles that are on two adjacent parallel lines simultaneously in, therefore knitting yarn can move on different circumscribed circles in the braiding process.

Axle yarn in the present embodiment is in described orthohexagonal center, and here, the position of axle yarn not only is confined to orthohexagonal center, as long as the axle yarn is arranged in the regular hexagon.

Certainly, in other embodiments, also a yarn can be set, have some holes in the braided fabric that at this moment weaves.
