The specific embodiment
We claim that the shell of fabric is a main body, and the cross section of inner chamber is a reinforcement.Some reinforcement main body of fabric is closo fabric not, and promptly main body has the cross section that (contains) more than not weave.C type and L type are meant the section shape of fabric body, and the fabric that the main body section is circular arc type or frame type belongs to the C type, and the fabric that the main body section is angle type belongs to the L type.
Be that the invention will be further described for example with braiding reinforcement three dimensional fabric as shown in Figure 7 below.
The braiding of fabric is begun to carry out the winding of weft yarn toward the D face by C face junction, and the main part of first braided fabric, main body adopt the L type to come and go latitude line weaving method successively, and its concrete operations are as follows:
(1) referring to Fig. 3, the fabric construction of three dimensional fabric is by the relative displacement of adjacent two row warp thread and wears latitude and realize interweaving.So we set adjacent two row warp thread is a pair of, the row at that stock-traders' know-how yarn place that can see fabric exterior are defined as high row, then classify low row as with its paired another.
(2) with internal layer ground floor opening, penetrate weft yarn by the C face of fabric body, wear to the D face later, with internal layer second layer opening, penetrate weft yarn by the second layer, wear face to C.Again later,, penetrate weft yarn by the 3rd layer, wear face to D with the 3rd layer of opening of internal layer by the C face.Below analogize, come and go successively from inside to outside and penetrate weft yarn to the surperficial second layer.
(3) then the height row are carried out relative displacement, shift length is the spacing of 4 spindles.Original height row move down after the displacement becomes low row, and originally low lists and move into is the height row.With outer second layer opening, penetrate weft yarn again, wear to the D face and turn one's head,, penetrate weft yarn, wear face to C by the second layer with outer second layer opening by fabric body C face.Again later,, penetrate weft yarn by the 3rd layer, wear face to D with the 3rd layer of opening of skin by the C face.Below analogize, come and go successively from inside to outside and penetrate weft yarn to the inner surface ground floor.
When braiding during to as shown in Figure 8 junction 2, carry out the braiding of reinforcement part, the warp thread of reinforcement part adopts longitude line weaving method to draw warp thread, and the concrete operation method that describes longitude line weaving method below in conjunction with Fig. 4 in detail is as follows:
(1) longitude line weaving method adopts paired tying-in method, draws two corresponding warp thread exactly on an original warp thread;
(2) longitude line weaving method is to add a warp thread as the warp thread that newly grows on each root warp thread of low row.The height that two of the warp thread that newly grows is respectively the warp thread of reinforcement surface of second order lists two corresponding positions, i.e. warp thread of growing in pairs.
(3) it should be noted that, the position mapping one by one of the warp thread that grows on former warp thread and the former warp thread, the position of former warp thread such as mapping be in n position of height row in other words, then the warp thread that grows on this warp thread also should mapping in Gao Lie and low n the position that is listed as.In Fig. 5, Fig. 6, the 1st position of low row, then two of the warp thread that grows of this warp thread should correspond respectively to the 1st position of introducing high row of warp thread and low row.The 3rd position of low row, then two of the warp thread that grows of this warp thread should correspond respectively to the 3rd position of high row of the warp thread that grows and low row.
Latitude line stretching method is adopted in the braiding of the reinforcement part (as two faces of the A among Fig. 8, B) of fabric ends.Describe the concrete operation method of latitude line stretching method in detail in conjunction with Fig. 5 to Fig. 7:
Referring to Fig. 7, we suppose that two faces that fabric body partly intersects are respectively C face, D face.With the warp thread of longitude line weaving method introducing reinforcement surface of second order, wherein the warp thread that bears of C face is as the warp thread of reinforcement surface of second order, and the warp thread that bears of D face must calculate tying-in quantity and tying-in distribution by the filling density of fabric.The warp thread that bears of D face is as weft yarn, weaves with the warp thread that bears of latitude line stretching method and C face, and concrete Weft insertion method is as follows:
With inner textile layer ground floor opening, the feeding weft yarn, weft direction is vertical with warp thread direction.With internal layer second layer opening, introduce weft yarn again.Below analogize, draw yarn from inside to outside successively to surperficial ground floor.Then height is misplaced,, introduce weft yarn inner textile layer ground floor opening.With internal layer second layer opening, introduce weft yarn again, the rest may be inferred, draws yarn from inside to outside successively to surperficial one deck.
After introducing second group of weft yarn, realized once interweaving.Utilize one group of back draw yarn can last group to draw yarn urgent, realize control to weft count.
Latitude line stretching method also can be used for the growth of warp thread, as " X " type fabric, this kind fabric can be regarded as by "＞" and "＜" two parts and form, and can set "＞" and be main body, and "＜" is reinforcement.Reinforcement adopts the wefting insertion rule to be easier to realize.
The braid method of C type reinforcement fabric has similarity in the braid method of L type reinforcement fabric.Simply introduce the integral weaving technology of C type reinforcement fabric below:
(1) braiding of main body: adopt the C type to come and go latitude line weaving method (see figure 2) successively along main direction, method of operating is with the L type.
(2) the reinforcement face preset warp thread: adopt longitude line weaving method, method of operating is with the L type.
(3) wefting insertion of thing two ends reinforcement face: the latitude line stretching method that is similar to the reinforcement face of L type fabric.Difference is with the warp thread of two parallel surfaces of main body as the weft yarn wefting insertion that interlocks.See Fig. 9.
(4) wefting insertion of reinforcement face in the middle of the fabric: adopt to come and go the latitude line weaving method wefting insertion, two that weft yarn comes and goes is enclosed within on the warp thread of internal layer correspondence position of main body (seeing 13 among Fig. 9).
