Abstract

The invention relates to a method for thin fabrics weaved with coarse yarn with non-twist or low twist. It is the harness wire combination made by each harness wire in the conventional loom machine and consisted of two shafts with certain length and small diameter or bearings which is set in harness eye of harness wire in the vertical with harness wire direction. Two shafts or bearings are assembled in parallel, between which there is a micro span. The span is formed to flat gap. When warp yarn passes through the gap in loom machine running, warp yarn with original bunchiness structure is pressed to lamellar structure by two shafts or bearings, and the warp yarn with lamellar structure is transmitted to cloth fell continuously; each harness wire combination is hanged on the harness frame and moves up and down with harness frame under the effect of lifting mechanism as the method of conventional loom machine so that each harness wire accomplishes respective open motion demanded by fabric organizing law, which passes through the gap between two shafts or bearings in harness wire combination.

Description

A kind of method that low twist low count yarn is made into the Boping fabric
Affiliated technical field
The present invention relates to a kind of woven weaving method, especially can use non-twist or low twist low count yarn to be made into the method for Boping fabric.
Background technology
The heald of existing loom has produced bigger fretting wear to warp thread.
Heald is the important parts of the harness motion during guiding warp thread and tractive warp thread are weaved, and has constituted the principal element to the warp yarn friction wearing and tearing.Existing heald duty, no matter be the steel disc heald, or steel wire heald, or plastic heddle, this friction is a sliding property, coefficient of friction is bigger, and more disadvantageously, exist with respect to warp thread and to weave motion under the unfavorable conditions than hightension, this produces bigger wearing and tearing when just making warp thread through heald inevitably, especially when weaving glass fiber, carbon fiber etc.
Existing weaving technology is difficult to be made into the comparatively fabric of Boping with rove.Because the harness eye form of existing heald determines it not possess the function with the warp thread flattening.
The price of fine yarn is generally than costliness, the especially high-performance fiber of rove.Carbon fiber for example, thickness no matter, though the mechanical index of unit line density is very nearly the same, under same Unit Weight, the price of 3K just is more than the several times of 12K.
Usually, after loom was weaved, it is big that the thickness of fabric and the size of weight per unit area correspondingly become with the increase of the thickness of yarn.For example in same factory, when the carbon fiber that with specification is the 3K of T300 is made into plain fabric, its thickness and Gram Mass are respectively 0.33 millimeter and 240 grams, and be the carbon fiber of the 12K of T700 when being made into plain fabric with specification, its thickness and Gram Mass increase to 0.66 millimeter and 650 grams respectively.As seen, the advantage that descends of the cost that adopts coarse yarn to bring will be offset along with the increase of the thickness of fabric and weight per unit area or be not obvious.
So, for reducing cost, use the more honest and cleaner rove of price, be made into and adopt spun yarn to compare the final fabric of similar thickness or unit are grammes per square metre is arranged, and do not wear and tear as much as possible or the less wear warp thread just becomes a kind of selection of worth pursuit.
Summary of the invention
Be difficult to be made into the Boping fabric in order to overcome above-mentioned rove, and the bigger deficiency of warp thread wearing and tearing, the invention provides a kind of on loom, the use and compare the more honest and cleaner rove of price with adopting spun yarn, be made into the method that the final fabric of similar thickness or unit are grammes per square metre is arranged with spun yarn, this method has not only reduced production cost, and has improved product performance index.
The technical solution adopted for the present invention to solve the technical problems is: every heald of traditional loom is designed to a heald assembly, by have axles certain-length, two minor diameters or bearing perpendicular to the heald direction be installed in the harness eye of heald and form; Two axles or bearing are mounted to abreast a small spacing distance each other, and this has just formed flat slit; During the loom operation, when warp thread passed through from the slit, the warp thread that is the pencil form was originally just flattened the slabbing form by two axles or bearing, and then, the warp thread that is pressed into sheet continues forward movement and enters fell; In woven process, each root heald assembly is as the mode in the common loom, be mounted on the heald frame, moved up and down by the effect of shedding mechanism with heald frame, each the root warp thread that passes in the slit that two axles from the heald assembly or bearing are constituted is finished the desired harness motion separately of fabric tissue rule respectively.So, reached the purpose that non-twist or low twist low count yarn is made into the Boping fabric.
The invention has the beneficial effects as follows, can be with thicker non-twist yarn, be directed to the one-tenth cloth zone of loom in the mode that is rolled into flat form, so not only knit and weave into the Boping fabric, also help to reduce production costs, improve the quality of products.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the schematic diagram of the embodiment of the invention.
1. upper bearing (metal)s among the figure, 2. lower bearing, 3. heald, 4. warp thread.
The specific embodiment
In the embodiment shown in fig. 1, every heald of traditional loom is designed to a heald assembly, its structure is shown in the left figure of Fig. 1, upper bearing (metal) 1 and lower bearing 2 are installed in the harness eye of heald 3, be miniature bearing, and axial length is bigger, so that form the flat slit between the metal (upper 1,2; When warp thread 4 passes through from the slit, the metal (upper 1,2 that the warp thread 4 of script pencil form is just rolled is rolled into lamellar morphology, the right figure that its mechanism schematically illustrates at Fig. 1, the rotation direction of bearing 1,2 is respectively shown in arrow b, c, the warp thread 4 that is rolled into sheet moves along the direction of arrow d, enters fell; In woven process, each root heald assembly is as the mode in the common loom, be mounted on the heald frame, moved up and down by the effect of shedding mechanism with heald frame, shown in arrow a, each the root warp thread 4 that passes in the slit that the metal (upper from the heald assembly is constituted is finished the desired harness motion separately of fabric tissue rule respectively.So weave.
Heald 3 is the steel disc shape, and upper bearing (metal) 1 and lower bearing 2 can be as the mounting means of the needle latch of latch needles in knitting, to write off or the mode of bolt shaft is fixed in the heald 3.
