fourthly, inspecting and gluing the woven grey cloth;
fifthly, dissolving the auxiliary warp water-soluble vinylon yarn in water according to the process requirement
After water is dissolved, the middle auxiliary warp yarn disappears, at the moment, all the fixed consolidation points of the drawn yarns for consolidation weaving at the auxiliary warp yarns fail, so that the cylindrical base cloth formed by interweaving the base cloth weft yarns with the upper base cloth warp yarns and the lower base cloth warp yarns is slightly pulled, and the elliptical hollow wiredrawing cloth can be formed, wherein the wiredrawing from the consolidation point (A ') to the consolidation point (F') and the wiredrawing from the consolidation point (A ") to the consolidation point (F") are wiredrawing passing through the symmetric center origin of the intersection of the long axis and the short axis of the ellipse, the wiredrawing section (BG) and the wiredrawing section (EJ) are wiredrawing passing through the symmetric center origin of the intersection of the long axis and the short axis of the ellipse at the ellipse, and the wiredrawing section (CH) and the wiredrawing section (DI) are wiredrawing passing through the symmetric center origin of the intersection of the long axis and the short axis of the ellipse at the ellipse;
so far, the production of the oval hollow wiredrawing cloth is finished.
And the elliptical cylindrical wiredrawing cloth can be of various varieties. Under the condition that the ratio of the long axis to the short axis of the elliptic cylindrical wiredrawing cloth is fixed, the length of the wiredrawing cloth passing through the origin of the symmetrical center of the intersection of the long axis and the short axis of the elliptic cylindrical wiredrawing cloth can be calculated, the wiredrawing length passing through the center of a circle is known, the length spanned by the wiredrawing in the auxiliary warp yarns can be known, and the force is assisted by the consolidation of the auxiliary warp yarns after the wiredrawing cloth is consolidated with the base cloth. And the back-and-forth distance is the whole drawn length, and then the base cloth point corresponding to the other base cloth point of the base cloth starts consolidation weaving. Finally, dissolving the water soluble vinylon, removing the fixing points of the drawn wires and the auxiliary warps, pulling the woven cylindrical fabric to two sides to form the elliptical cylindrical fabric, wherein the drawn wires all pass through the symmetrical center origin point of the intersection of the major axis and the minor axis of the ellipse.
The major Axis (AF) of the elliptical tube cloth is close to, because the weaving shrinkage and the tubular cloth are pulled to become the elliptical tube cloth, the line segment (AF) is certainly longer than the length of the major axis of the elliptical tube cloth, only the fixed point (A ') and the fixed point (A ') which are close to the fixed point (A) and the fixed point (B '), which are close to the fixed point (B) can be selected as the longest wiredrawing which can pass through the original point, and the wiredrawing length is not required to be increased by the auxiliary warp, therefore, the wiredrawing segment (A ' F ') and the wiredrawing segment (A ' F ') can be directly woven, which is particularly noticed during weaving, and the minor axis (PO) of the elliptical tube cloth is difficult to weave like the 180-degree curved dead point during the 0-360-degree curved axis motion, and the turning is avoided as much as possible, so that the wiredrawing segment (PO) is not arranged in the weaving.
Furthermore, the third shuttle, the fourth shuttle and the fifth shuttle of drawn weft yarns and the cylindrical base fabric are fixedly woven to a fixing point (B). Then, the auxiliary warp yarn fixing nodes (M) and the auxiliary warp yarn fixing nodes (N) are fixedly connected with the fixing nodes (G) of the cylindrical base fabric after going back and forth through three warps and one weft, and the cylindrical base fabric is fixedly woven. After water dissolution, the consolidation point (M), the consolidation point (N), the drawn weft yarn and the auxiliary warp yarn are not consolidated any more. When the lower base cloth of the upper base cloth is staggered outwards to form the elliptic cylindrical cloth, the drawn wire pulls the lower base cloth of the upper base cloth from the fixed point (B) to the fixed point (G) and passes through the original point.
The circulation is continued in turn, and the whole elliptic cylinder has countless drawn wires which pass through the symmetrical center origin point of the intersection of the long axis and the short axis of the ellipse at different positions and different lengths.
Specifically, the drawing weft yarns are dissolved in water and lose efficacy from the fixing point (A) to the fixing point (B), then to the fixing point (M), then to the fixing point (N), then to the fixing point (G) and then to the fixing point (F) in the third shuttle to the fifth shuttle, and finally, the drawing weft yarns are fixed with the cylinder from the drawing section (AB) and then to the drawing section (GF) and are fixed with the cylinder base cloth, and the drawing section (BG) passing through the origin of the ellipse becomes drawing.
And the drawing weft yarns are dissolved in water and lose efficacy from the fixed point (F) to the fixed point (E), then to the fixed point (N) and the fixed point (M), then to the fixed point (J) and then to the fixed point (A) from the eighth shuttle to the tenth shuttle, and finally, the drawing weft yarns are solidified with the cylindrical base fabric from the drawing section (FE) and then to the drawing section (JA) and then are solidified with the cylindrical base fabric to form drawing sections (EJ) passing through the origin of the ellipse.
And from the thirteenth shuttle to the fifteenth shuttle, drawing weft yarns are dissolved in water and lose efficacy from the consolidation point (A) to the consolidation point (C) to the consolidation point (U) to the consolidation point (V) and then to the consolidation point (H) to the consolidation point (F), and finally the drawing weft yarns are consolidated with the cylinder from the drawing section (AC) to the drawing section (HF) and then consolidated with the cylinder base fabric to form drawing yarns of the drawing section (CH) passing through the origin of the ellipse.
And from the eighteenth shuttle to the twentieth shuttle, the wiredrawing weft yarns are from the fixed point (F) to the fixed point (D), then to the fixed point (V) and the fixed point (U), then to the fixed point (I), then to the fixed point (A), and finally the fixed point (V) and the fixed point (U) are dissolved in water and lose efficacy, and the wiredrawing weft yarns are fixed with the cylindrical base fabric from the wiredrawing section (FD) and then to the wiredrawing section (IA) and then fixed with the cylindrical base fabric to form wiredrawing section (DI) wiredrawing passing through the origin of the ellipse.
From the twenty-third to twenty-sixth shuttles, the drawn weft yarn is drawn from the point of consolidation (A) to the points of consolidation (A ') to (F) and then to (F') as a drawn section (A 'F') passing through the origin of the ellipse, and from the point of consolidation (A ") to (F") as a drawn section (A "F" drawing) passing through the origin of the ellipse
Further, the cylindrical fabric cannot be an elliptical cylindrical fabric without calculating the drawn length of the wire with different lengths passing through the origin of the symmetric center where the major axis and the minor axis of the ellipse intersect.
Further, without the auxiliary warp yarns, all the draw and draw lengths are also unlikely to pass through the origin of the symmetry of the intersection of the major and minor axes of the ellipse.
The drawing length of the elliptic cylindrical cloth is calculated by calculus.
For the purpose of simple explanation, a popular field engineering simple method is used, a rope with a fixed length, preferably a rope with small elasticity, such as a thin steel wire rope, is fixed on a nail at two ends, and the rope is straightened by a pen, so that an ellipse is drawn by a circle.
The distance of the two nails and the length of the cord need to be determined.
The length of the ellipse to be drawn is set to be 2a, the width is set to be 2b, the distance between the two nails is set to be 2c, and the length of the rope is set to be L.
Then:
i.e. c is equal to the square root of the difference of the square of a minus the square of b.
Then:
i.e. L is equal to the length of the ellipse.
This method is based on the ratio of the major axis of the ellipse to the minor axis of the ellipse provided by the client, and will not be described herein.
Then the lengths of the drawn wires passing through the symmetrical center origin point of the cross of the long axis and the short axis of the ellipse at different positions can be actually measured, then the consolidation points temporarily borrowed by the auxiliary warp yarns, such as a consolidation point (M), a consolidation point (N), a consolidation point (U) and a consolidation point (V), are correspondingly found, and then the production weaving shrinkage is combined for production.
Compared with the prior art, the invention has the following advantages and effects:
the elliptical hollow wiredrawing cloth can be woven only by a double-faced double-shuttle box shuttle loom, and is not like flat hollow wiredrawing cloth, but also can be woven in a three-dimensional manner by means of a height-fixing piece, and is not like cylindrical hollow wiredrawing cloth, and is more complicated and fussy because the double-faced double-shuttle oblique warp shuttle loom is used for weaving. The elliptical hollow drawn fabric can be successfully woven on a double-faced double-shuttle box shuttle loom by using the weaving method of the invention only by using water-soluble vinylon yarn as auxiliary warp yarn and carefully calculating the elliptical cylinder and the drawn yarn, and is easier to compare. Therefore, the market prospect is very good.
