Technical Field

The invention relates to a warp knitting process of fabric, in particular to a warp knitting blind curtain.

Background

Generally, a light-transmitting curtain and a light-shielding curtain are required to be installed on the curtain to achieve the functions of light shielding and light transmission, and the raw material cost and the installation cost are high. And the width of the curtain cloth is fixed, so that the width of the curtain can not be flexibly adjusted according to the width of the door and window.

In order to solve the above problems, the light transmitting state or the light blocking state is controlled by adjusting the rotation angle of the blind after the louver is installed, but when the louver is in the light transmitting state, the space between the louvers is not blocked at all, and when the louver is in the light transmitting state, the image cannot be blocked. Besides, the material of the louver is different from that of the textile cloth, so that the exquisite effect of the textile cloth cannot be achieved.

Disclosure of Invention

In view of the above problems, the invention discloses a warp-knitted venetian blind, which is formed by integrally knitting a chain knitting line, a weft lining line and a jacquard thread into a blind body, wherein the blind body comprises a plurality of venetian blind tissues and a selvage-pulling tissue for connecting two adjacent venetian blind tissues. The louver tissue consists of 2 thick blades and 1 thin blade in the middle, the first connecting part and the second connecting part in the edge-pulling tissue are formed by weaving jacquard threads, the edge-pulling tissue can be conveniently torn off to obtain louver tissues separated from each other, then 3 blades in each group of louver tissue are bent into a U shape and are arranged in order in front of doors and windows to form a warp-knitted louver curtain, two different using states of shading and light transmitting are realized by rotating the shading blades in the louver tissue, and the light transmitting state can also be used for shading images. When not in use, the blind is pulled to one side of the door and window, and the occupied space is small.

The process scheme of the invention is as follows:

a warp knitting blind curtain is knitted into a curtain body by integrally forming a chain knitting line, a weft lining line and a jacquard thread, and the curtain body comprises: the single louver tissue comprises a transparent blade and two shading blades arranged on two sides of the transparent blade; the edge-pulling tissues are used for connecting two adjacent shutter tissues, and each edge-pulling tissue comprises a first connecting part, a second connecting part and an intermediate connecting part arranged between the first connecting part and the second connecting part; the first connecting part and the second connecting part are respectively formed by weft knitting of a lifting thread or a weft insertion thread, one end of the lifting thread or the weft insertion thread is fixed on the shading blades of the louver tissue, and the other end of the lifting thread or the weft insertion thread is fixed on the middle connecting part.

Furthermore, the jacquard threads or the interlining threads of the first connecting part and the second connecting part are fixedly connected with the chain knitting threads on the shading blades by one needle, and the chain knitting threads on the middle connecting part are connected by two or more needles.

Furthermore, the weaving density of the lining weft threads and the lifting threads of the light-transmitting blades is smaller than that of the shading blades, so that the thickness of the light-transmitting blades is smaller than that of the shading blades.

Furthermore, the intermediate connecting part is formed by weaving chain knitting threads, lifting threads and weft insertion threads, and the width of the intermediate connecting part is 3 needle positions or more of weft movement of the lifting threads.

Further, the width of the single sheet of the light-transmitting blade and the width of the single sheet of the light-shielding blade are equal or different.

Furthermore, the jacquard threads or the lining wefts of the first connecting part and the second connecting part are torn, and the torn threads are completely fixed on the middle connecting part, so that a plurality of louver tissues separated from each other are obtained.

Furthermore, 3 blades in the louver tissues are bent into a U shape, a plurality of louver tissues are continuously arranged in front of the door and window, and the tops of 2 adjacent shading blades are clamped by a fixing component to form the louver curtain.

Furthermore, when the blades of the shutter tissues are U-shaped, the shutter curtain is in a light-transmitting state; and rotating the shading blades by 90 degrees to enable the shading blades to be partially overlapped, so that the shutter curtain is in a shading state.

Furthermore, the louver tissues can be combined by any number to form the louver curtain suitable for the width of doors and windows.

Furthermore, the shutter curtain is formed by arranging a plurality of shutter tissues with different patterns.

The invention has the beneficial effects that:

(1) the blind curtain is integrally woven into the curtain body by the warp knitting process, and then the edge pulling tissues are directly separated from the curtain body to form the mutually independent blind blades, so that the procedures of cutting and re-sewing the blind blades are omitted, the textile fabric is highly utilized, the raw materials are saved, the labor and the re-ironing cost are reduced, and the processing steps are simplified.

(2) The louver tissue is separated from the edge-pulling tissue, the edge-pulling tissue is abandoned after separation, and as the torn lifting threads or the broken weft insertion threads are completely connected to one side of the edge-pulling tissue, the edges of the louver tissue are smooth and flat, and can be designed into uniform sawtooth shapes or small crescent waves, so that the edges of the louver are attractive and elegant, and curling and ironing are not needed any more. Saves raw materials, reduces the labor and ironing cost, greatly improves the economic benefit and simplifies the processing steps.

(3) Because the jacquard thread or the weft-lined thread is fixed on the middle connecting part by 2 needles or more, 1 needle is fixed on the louver structure, the tension of the jacquard thread or the weft-lined thread on the louver structure is less than that of the selvage-pulling structure, and after the fabric is shaped, the first connecting part and the second connecting part are torn off, the torn-off threads are all connected to one side of the selvage-pulling structure.

(4) The blind window curtain realizes two different use states of shading and transmitting light by rotating the shading blades in the blind tissues, and the transmitting state can also shade images.

(5) The blind curtain can be conveniently installed according to different widths of doors and windows, and only the blind tissues are combined in any number according to the required width.

(6) The venetian blind is woven by a warp knitting process, and is fixed by the jacquard threads and the weft insertion threads in the warp direction and the chain knitting threads in the weft direction. In the height direction of the curtain, the curtain can be directly cut by hot melting according to the required length without sewing the bottom edge.

(7) The shutter tissues of the shutter curtain can be woven into different patterns or colors, and can be combined randomly, so that the attractiveness is improved.

Detailed Description

Example 1

The present invention will be described in further detail with reference to the accompanying drawings and examples. The specific embodiments described herein are merely illustrative of the invention and are not to be construed as limiting the invention. In addition, it should be noted that, for convenience of description, only a part of structures related to the present invention, not all of the structures, are shown in the drawings.

Referring to fig. 1-7, the warp-knitted venetian blind of the present invention is formed by integrally knitting a chain knitting line, a weft lining line and a jacquard thread into a blind body, wherein the weft lining line is knitted on the bottom surface of the blind to form a weft lining and padding yarn of the blind; the jacquard threads are woven on the upper surface of the curtain to form jacquard of the fabric; the chaining thread is woven in the warp direction of the curtain to form a chaining of the fabric, and is used for fixedly connecting the lining weft thread and the jacquard thread arranged in the weft direction. The curtain body includes that a plurality of tripes organize 1, single tripe organizes 1 has 3 blades to constitute, including a slice printing opacity blade 11 and two shading blade 12 of setting in printing opacity blade 11 both sides, shading blade 12 and printing opacity blade 11 are according to the line of lining weft and the different formation of carrying the line knitting density, the lining latitude pad yarn of printing opacity blade 11 is very thin, can cancel even, only have to compile the chain line and carry the line and weave into the gauze that has the mesh form, the lining latitude pad yarn of shading blade 12 is thicker, the shading blade 12 of weaving does not have the mesh, compact structure, almost opaque. So that the thickness of the light transmitting blade 11 is smaller than that of the light shielding blade 12.

Furthermore, the device also comprises a flange tissue 2 used for connecting two adjacent shutter tissues 1. The selvage forming portion 2 includes a first connecting portion 21, a second connecting portion 22, and an intermediate connecting portion 23 disposed between the first connecting portion 21 and the second connecting portion 22. The first connecting portion 21 and the second connecting portion 22 are composed of a jacquard thread or a weft insertion thread, when the first connecting portion and the second connecting portion are woven by the jacquard thread, the shading blades 12 and the middle connecting portion 23 are connected in the warp direction by the jacquard thread, weft insertion padding thread is eliminated, the jacquard thread can move 1 needle empty and 2 needles empty or move 2 needles empty and the like in any combination to form meshes of different shapes, when the first connecting portion and the second connecting portion are woven by the weft insertion thread, the shading blades 12 and the middle connecting portion 23 are connected in the warp direction by the weft insertion thread, the jacquard thread of the first connecting portion and the second connecting portion is eliminated, the weft insertion thread is connected with the shading blades 12 in the weft direction from the middle connecting portion 23, and then the middle connecting portion 23 is connected with the shading blades 12 in the weft direction, and the first connecting portion and the second connecting.

One end of the jacquard thread or the interlining thread of the first connecting part 21 and the second connecting part 22 is fixedly connected with the chaining thread of the intermediate connecting part 23 by two needles or more, namely, the jacquard thread or the interlining thread is firstly fixedly connected on the chaining thread at the most edge on the intermediate connecting part 23, and then continuously moves to the other chaining thread on the intermediate connecting part 23 in the weft direction and is fixed. At this time, one end of the lift thread or the weft interlining thread is fixed to the knitted chain line of the intermediate connecting portion 23 by two needles. The warp yarns or weft interlining yarns in the same weft direction are simultaneously fixed to the three knitting yarns of the intermediate connecting portion 23, and are referred to as knitting yarns that fixedly connect the intermediate connecting portion 23 with three stitches. Similarly, the other ends of the weft threads or the weft interlining threads of the first connecting portion 21 and the second connecting portion 22 are fixed to the knitting threads on the shade blade with one needle. When the threads of the first connecting portion 21 and the second connecting portion 22 are torn, since the tension of the blind tissues 1 is smaller than that of the selvage tissues, the torn threads are completely fixed to the intermediate connecting portion 23, and a plurality of blind tissues 1 separated from each other are obtained. The picture of the edge-pulled tissue and the connected two shading leaves is shown in figure 4; FIG. 5 is a pictorial view of a tissue tear at the selvedge to break the first and second connecting portions.

In order to make the intermediate connecting portion 23 have two or more positions for fixing the jacquard thread or the interlining thread, the width of the intermediate connecting portion 23 is a certain width for shifting the jacquard thread weft by 3 needle positions or more, and the intermediate connecting portion 23 has a certain thickness without canceling the interlining yarn, thereby facilitating the tearing of the jacquard thread or the interlining thread of the first connecting portion 21 and the second connecting portion 22 by force. Because the selvage forming fabric 2 is abandoned at last, in order to save cost, the middle connecting part 23 does not need to be too wide, and the middle connecting part can be used for 3-5 weft needle positions generally. FIG. 6 is a warp knitting layout diagram of the middle connecting portion with a width of 5 needle positions; FIG. 7 is a warp knit layout with a 3 stitch spacing for the width of the intermediate link.

Because the weaving mode can be conveniently set in the warp knitting process, the widths of the light-transmitting blades 11 and the light-shading blades 12 can be equal or unequal.

Furthermore, 3 blades in the louver tissues 1 are bent into a U shape, a plurality of louver tissues 1 are continuously arranged in front of the door and window, and the tops of the adjacent 2 shading blades 12 are clamped by a fixing component to form the louver curtain. When the blades of the shutter organization 1 are U-shaped, namely the shading blades 12 are approximately vertical to the door and the window, the light-transmitting blades 11 are approximately parallel to the door and the window, and the shutter curtain is in a light-transmitting state; the blind blades 12 are rotated by 90 degrees so that the blind blades 12 are partially overlapped with each other, the blind blades 12 are approximately parallel to the door, and the window blind is in a blind state. If the U-shaped state is adopted, when the rotation angle of the shading blade is larger than zero and smaller than 90 degrees, the shading blade and the door and window have a certain inclination angle, so that the curtain is in a half shading state. The transparent blade 11 has a certain image shading function because the transparent blade can be woven into different thicknesses according to the weft insertion yarns.

Because the tops of the adjacent 2 shading blades are clamped by the fixing component, the blind window curtain is formed. Thus, the number of blind groupings can be any combination to form a blind that fits the width of a window or door. For example, 5 groups of shutter tissues can be combined together, or 15 groups of shutter tissues can be combined together conveniently to form the curtain. Meanwhile, the patterns of each group of louver tissues can be the same or different according to requirements.

When the shutter curtain is used, three blades of each group of shutter tissues are bent into a U shape, two adjacent shutter blades are overlapped and clamped at the top by a commercially available curtain pulling piece, then the clamping piece is arranged on the curtain rod, and the curtain can move to one side of a door and a window after being opened along with the movement of the clamping piece. When the blind is opened, the other pull rope controls the clamping piece to rotate, and when the clamping piece is vertical to the door and window, the blind is opened and appears in a U shape in front of the door and window or is folded and positioned at one side of the door and window. When the window curtain clamping piece is rotated and the window curtain clamping piece is parallel to the door and window, the shading blades are directly overlapped by the door and the window curtain is in a shading state.
