Description

Technical Field

[0001] The invention belongs to the technical field of textile weaving technology, and in particular relates to a leno double-layer home wear jacquard fabric and a preparation method thereof. Background Art

[0002] In the field of modern textile technology, double-layer fabrics are widely used in many fields such as baby clothing and household products due to their unique breathability, excellent soft touch and good fluffy effect, and are deeply loved by consumers. Most of the traditional double-layer gauze structures are designed and transformed based on the basic jacquard technology. Although these designs meet the basic needs of the market to a certain extent, their innovation and practicality are relatively limited in today's market environment that pursues higher quality and more unique appearance.

[0003] In order to break through this limitation, the textile industry began to explore the application of more diversified organizational structures and technologies in the production of double-layer gauze fabrics. Among them, leno, as a long-standing twisted yarn organizational structure, has become a highly promising innovation direction with its unique three-dimensional effect and rich texture changes. The special feature of leno organization is that it achieves the interlacing and interweaving of yarns through complex threading and twisting processes and double weaving shaft weaving methods, thus forming a unique three-dimensional beauty.

[0004] However, combining the leno structure with the gauze jacquard to create a more three-dimensional and novel double-layer gauze fabric faces many technical challenges. First of all, the special threading and twisting process of leno poses a great challenge to the normal weaving of the double-layer structure. Since the leno structure requires complex yarn interweaving, the stability and controllability of the weaving process are greatly reduced when the leno structure is introduced into the double-layer fabric. Secondly, the position and treatment of the junction point also need to be reconsidered. In a double-layer fabric, the junction point is the key part connecting the two layers of yarn, and its position and shape directly affect the overall appearance and feel of the fabric. How to retain the three-dimensional appearance of the leno while combining well with another layer of tissue and making the junction point more concealed and regular has become a technical problem that needs to be solved urgently. Summary of the invention

[0005] In view of the deficiencies in the prior art, the object of the present invention is to provide a gauze double-layer home wear jacquard fabric with good air permeability, high softness and a texture appearance suitable for home use.

[0006] The present invention also provides a preparation method thereof, which solves the problem that when the ground warp and the twisted warp of the upper layer leno itself are twisted with each other, the plain warp yarn of the lower layer is twisted together with the upper layer twisted warp and the ground warp in each cycle, so that weaving cannot proceed smoothly. At the same time, the leno is perfectly connected with the plain weave of the lower layer, so that the connection point is not visible, thereby realizing an integrated tissue structure.

[0007] The difficulties solved by the present invention are two points. The first point is that when the ground warp and the twisted warp of the upper layer of leno itself are twisted with each other, the plain warp yarn of the lower layer must be linked with the upper layer of twisted warp and ground warp in each cycle at the same time. On the same reed tooth, it is easy to cause the lower warp yarn and the upper layer of ground warp to be twisted together with the twisted warp at the same time, so that weaving cannot proceed smoothly. To solve the problem that the lower layer of warp yarn is not affected by the upper layer of twisted warp, it is necessary to adjust the weft drawing method and the organization structure. The second point is how to perfectly connect the leno with the plain weave of the lower layer so that the connection point is not visible and the integrated organization structure is perfectly realized.

[0008] The gauze double-layer home wear jacquard fabric of the present invention has a fabric structure of one side full of gauze and one side full of plain weave, which are combined and matched through joint points.

[0009] The method for preparing the leno double-layer jacquard fabric for home clothes of the present invention comprises the following steps:

[0010] Weave design → warp drawing → weaving;

[0011] The organization is a double layer of leno 5 and plain weave:

[0012] The upper weave is leno 5:

[0013] 2 twisted warps + 3 ground warps + empty reed is the minimum circulation unit;

[0014] The lower weave is 1 / 1 plain weave;

[0015] The organization diagram of the gauze double-layer home wear jacquard fabric is as follows Figure 1 As shown, the organizational breakdown diagram is as follows Figure 2 As shown, Figure 2 The upper left in the middle is the connection point location diagram, the upper right is the leno weave diagram, and the lower left is the plain weave diagram.

[0016] The joining point method is point-to-point joining. The upper and lower joining points are selected when the warps are twisted and joined with the lower plain warp points in a "bottom-to-top" manner. The diamond-shaped joining arrangement is used and the position is hidden under the twisted warps of the gauze. This joining method can better conceal the joining points and make the fabric surface look smoother.

[0017] In the organization design process, the warp pattern is arranged as follows: the yarns of two warp shafts, a ground shaft A and an upper shaft B, are woven together; the arrangement of the ground shaft A is 2 lower plain weaves, 3 upper leno parts of the ground warp A + 2 upper twisted warps of the upper shaft B, which are circulated twice to form the left and right half twisted lenos of the leno respectively; in the middle space part of the left and right half twisted lenos, the corresponding lower layer position has two warp yarns on the ground shaft A to form a group of plain weaves, which are woven together with the upper space part.

[0018] The drawing-in process uses 15 heald frames, the number of dropper rows×the number of pieces: 8×1229, the drawing-in method of the dropper: 1, 2, 3, 4, 5, 6 sequential drawing; the upper layer tissue adopts leno 5, the lower layer tissue adopts 1 / 1, and the upper layer density is twice the lower layer density.

[0019] The number of reed teeth and the drawing-in method in the warp drawing process are as follows: the number of reed teeth is 7: 2 reed teeth of the lower layer are 1 / 1, and are drawn into the 7th and 8th heald frames. At this time, the special heald frames of leno are not drawn (the special heald frames of leno are 1 to 4, which are not displayed in the normal drawing-in process); 3 ground warps of the upper layer leno are drawn into the 11th, 12th and 13th heald frames, and 2 twisted warps of the upper layer leno are drawn into the 9th and 10th heald frames. At this time, the special heald frames 1 and 2 of leno are drawn in on the left, and the drawing-in method is as shown in the diagram. The half-twisted leno on the left is parallel to the plain weave of the lower layer with the fabric; at this time, there are 2 empty reed teeth on the upper layer leno, and 2 warp yarns of the lower layer 1 / 1 organization are drawn into the 7th and 8th heald frames. At this time, the special leno heald frame is not worn, and the lower plain weave at the empty reed of the upper leno is completely connected to the left and right plain weaves; the other number of insertions is 7: 2 1 / 1 of the lower layer are worn in the 7th and 8th heald frames, and the special leno heald frames 1 to 4 are not worn at this time; 3 ground warps of the upper leno are worn in the 11th, 12th and 13th heald frames, and 2 twisted warps of the upper leno are worn in the 9th and 10th heald frames. At this time, the special leno heald frames 3 and 4 are worn on the right, and the weaving method is according to the diagram. The half-twisted leno on the right side is parallel to the lower plain weave and the fabric. The above is a complete weaving method. In the ordinary heald frame weaving, pages 5 and 6 are the edge weaving healds, which are not in the above arrangement.

[0020] Schematic diagram of drawing in the heald and reed Figure 3 As shown, the red frame is the schematic diagram of drawing in the heddle, and the blue frame is the schematic diagram of drawing in the reed.

[0021] Drawing in: The heald frame of the leno weave is quite special. When drawing in, the ground warp and the twisted warp are respectively inserted into two rows of ordinary healds. The one inserted into the ground warp is called the ground heald, and the one inserted into the twisted warp is called the back heald. Because of the double-layer weave, the upper and lower layers of weave are respectively inserted into different heald frames, and the tension of the yarns of each weave must be controlled separately. The tension of the heald frame of the upper twisted warp and the ground warp must also be controlled separately to ensure that the yarn has enough tension to twist left and right with the twisted warp when the twisted warp and the ground warp are twisted with each other. After the upper ground warp and the lower warp are respectively inserted into the ordinary healds, the twisted warp and the ground warp are led forward together to pass through the twisted heald, and the lower warp is on the outside of the twisted heald, and then the three are inserted into the same reed tooth together.

[0022] Empty reed: has only two threads and one reed tooth.

[0023] Twisted warp and ground warp: Leno 5 consists of two independent yarns. Two twisted warps and three ground warps are inserted into the first two rows of heald frames of the base heald, and then passed through the base heald together into a reed tooth. The empty reed is usually in the middle of two groups of twisted warps. The "empty reed" problem caused by the twisted warp sheet will cause gaps between the yarns of the lower plain weave due to the existence of the twisted warp sheet. However, the lower plain weave of the double-layer fabric exists as a separate organization, and the plain weave cannot have empty reeds. If there is an empty reed in the plain weave, there will be a large gap, which is inconsistent with the density of other lower plain weaves, affecting the overall appearance and poor thermal insulation performance.

[0024] The only way to solve this problem is to adjust the floating length of the weave. In the weave diagram at the upper empty reed, the upper warp yarn is set to 0 (empty reed), and the lower warp yarn is covered with the floating length to make the lower warp yarn single layer show a plain weave. Figure 4 As shown in the figure, the blue frame is the twisted warp, the red frame is the ground warp, and the red frame is the position of the upper leno reed.

[0025] The warp yarn and the weft yarn have the same fineness, the warp yarn uses a plied yarn, and the weft yarn uses a single yarn.

[0026] The warp yarn is a combed ring-spun 80 / 2 yarn, and the weft yarn is a combed ring-spun 40 Ne yarn.

[0027] The warp and weft yarns use yarns with the same fineness but different strengths. The warp plied yarns have high strength, which ensures that the yarns provide sufficient strength when twisting each other, avoiding the stoppage or fabric defects caused by the breakage of the yarns when twisting. The warp and weft use the same yarn fineness to ensure the overall feel is consistent, and the feel will not become stiff due to the influence of the twisted warp, and the softness of the fabric will not deviate from the warp and weft due to the difference in yarns.

[0028] In the weaving process, the tension of the upper shaft B is controlled at 350-400N, the tension of the ground shaft A is controlled at 2500-3000N, and the weaving process is reverse weaving.

[0029] Preferably, the tension of the earth axis A is 2800N.

[0030] The average speed of the weaving process is 350 rpm.

[0031] The shrinkage of the lower plain weave cannot be consistent with that of the upper ground warp. Considering the cost, we choose two-axis weaving. After multiple adjustments, considering the difference in shrinkage of the two tissues, the tension of the lower axis is controlled below 3000N, with 2800N being the best. The average speed is 350 rpm, and the efficiency is above 80%. In order to ensure that the pattern of the leno is not destroyed, the weaving is reversed and reversed during dyeing and finishing.

[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] (1) The present invention combines the special twisted yarn structure of the leno weave with the gauze jacquard technology, and has a novel appearance and texture with a three-dimensional visual sense. By redesigning the weave diagram, optimizing the drawing and twisting processes, and adjusting the weaving parameters, the overall performance and aesthetics of the double-layer fabric are improved while retaining the three-dimensional beauty of the leno.

[0034] (2) Compared with conventional double-layer fabrics, the gauze double-layer home wear jacquard fabric of the present invention has a good appearance texture, better air permeability and softness, and its texture appearance is suitable for home use.

[0035] (3) The present invention solves the problem that when the ground warp and twisted warp of the upper layer of leno are twisted with each other, the plain warp yarn of the lower layer is twisted together with the upper layer of twisted warp and ground warp in each cycle, so that weaving cannot proceed smoothly. At the same time, the leno is perfectly connected with the plain weave of the lower layer, and the connection point is not visible, making the fabric surface more regular and realizing an integrated tissue structure. Compared with conventional double-layer fabrics, it has a good appearance texture and better softness. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] The present invention will be further described below with reference to the embodiments.

[0044] Unless otherwise specified, all raw materials used in the examples are commercially available.

[0045] Example 1

[0046] The preparation method comprises the following steps:

[0047] Weave design → warp drawing → weaving;

[0048] The organization is a double layer of leno 5 and plain weave:

[0049] The upper weave is leno 5:

[0050] 2 twisted warps + 3 ground warps + empty reed is the minimum circulation unit;

[0051] The lower weave is 1 / 1 plain weave;

[0052] The organization diagram of the gauze double-layer home wear jacquard fabric is as follows Figure 1 As shown, the organizational breakdown diagram is as follows Figure 2 As shown, Figure 2 The upper left in the middle is the connection point location diagram, the upper right is the leno weave diagram, and the lower left is the plain weave diagram.

[0053] The joining point method is point-to-point joining. The upper and lower joining points are selected when the warps are twisted and joined with the lower plain warp points in a "bottom-to-top" manner. The diamond-shaped joining arrangement is used and the position is hidden under the twisted warps of the leno.

[0054] In the organization design process, the warp pattern is arranged as follows: the yarns of two warp shafts, a ground shaft A and an upper shaft B, are woven together; the arrangement of the ground shaft A is 2 lower plain weaves, 3 upper leno parts of the ground warp A + 2 upper twisted warps of the upper shaft B, which are circulated twice to form the left and right half twisted lenos of the leno respectively; in the middle space part of the left and right half twisted lenos, the corresponding lower layer position has two warp yarns on the ground shaft A to form a group of plain weaves, which are woven together with the upper space part.

[0055] The drawing-in process uses 15 heald frames, the number of dropper rows×the number of pieces: 8×1229, the drawing-in method of the dropper: 1, 2, 3, 4, 5, 6 sequential drawing; the upper layer tissue adopts leno 5, the lower layer tissue adopts 1 / 1, and the upper layer density is twice the lower layer density.

[0056] The number of reed teeth and the method of drawing in the warp drawing process are as follows: the number of reed teeth is 7: 2 reed teeth of the lower layer are 1 / 1, and are drawn in the 7th and 8th heald frames. At this time, the special heald frames of leno are not drawn in (the special heald frames of leno are 1 to 4, which are not displayed in the normal drawing in); 3 reed teeth of the upper layer leno are drawn in the 11th, 12th and 13th heald frames, and 2 reed warps of the upper layer leno are drawn in the 9th and 10th heald frames. At this time, the special heald frames 1 and 2 of leno are drawn in on the left, and the drawing in method is as shown in the diagram, and the half-reed leno on the left is parallel to the plain weave of the lower layer with the fabric; at this time, there are 2 empty reed teeth on the upper layer leno, and 2 reed teeth on the lower layer are drawn in. The warp yarn of 1 / 1 organization is passed through the 7th and 8th heald frames. At this time, the special heald frames of leno are not passed through. The lower plain weave at the empty reed of the upper leno is completely connected to the left and right plain weaves. The other number of insertions is 7: 2 1 / 1 of the lower layer are passed through the 7th and 8th heald frames. At this time, the special heald frames 1 to 4 of leno are not passed through; 3 ground warps of the upper leno are passed through the 11th, 12th and 13th heald frames, and 2 twisted warps of the upper leno are passed through the 9th and 10th heald frames. At this time, the special heald frames 3 and 4 of leno are passed through on the right. The weaving method is according to the diagram. The half-twisted leno on the right is parallel to the lower plain weave and the fabric. The above is a complete weaving method. In the ordinary heald frame weaving, pages 5 and 6 are the selvedge weaving healds, which are not included in the above arrangement. The specific details are shown in Table 1. The schematic diagram of weaving and reeding is as follows. Figure 3 As shown, the red frame is the schematic diagram of drawing in the heddle, and the blue frame is the schematic diagram of drawing in the reed.

[0057] Table 1 Number of reed teeth and threading method in the warp drawing process

[0058]

[0059] The upper empty reed has only two threads and one reed tooth.

[0060] By adjusting the floating length of the weave, the weave diagram uses the upper and lower layer design method at the upper empty reed. The upper warp yarn is set to 0 (empty reed), and the lower layer uses the floating length method to cover the upper empty warp, so that the lower warp yarn single layer shows a plain weave. Figure 4 As shown in the figure, the blue frame is the twisted warp, the red frame is the ground warp, and the red frame is the position of the upper leno reed.

[0061] The warp yarn is a combed ring-spun (CM) 80 / 2 yarn, and the weft yarn is a combed ring-spun (CPT) 40 Ne yarn.

[0062] In the weaving process, the tension of the upper shaft B is controlled at 380N, the tension of the ground shaft A is controlled at 2800N, the average speed is 350 rpm, and the weaving process is reverse weaving.

[0063] Example 2

[0064] Same as Example 1, except that: in the weaving process, the tension of the upper shaft B is controlled at 350N, and the tension of the ground shaft A is controlled at 2500N.

[0065] Example 3

[0066] Same as Example 1, except that in the weaving process, the tension of the upper shaft B is controlled at 400N, and the tension of the ground shaft A is controlled at 3000N.

[0067] Example 4-1

[0068] Same as Example 1, except that: in the weaving process, the tension of the upper shaft B is controlled at 330N, and the tension of the ground shaft A is controlled at 2500N.

[0069] Example 4-2

[0070] Same as Example 1, except that: in the weaving process, the tension of the upper shaft B is controlled at 330N, and the tension of the ground shaft A is controlled at 2800N.

[0071] Example 4-3

[0072] Same as Example 1, except that: in the weaving process, the tension of the upper shaft B is controlled at 330N, and the tension of the ground shaft A is controlled at 3000N.

[0073] Example 4-4

[0074] Same as Example 1, except that: in the weaving process, the tension of the upper shaft B is controlled at 420N, and the tension of the ground shaft A is controlled at 2500N.

[0075] Embodiment 4-5

[0076] Same as Example 1, except that: in the weaving process, the tension of the upper shaft B is controlled at 420N, and the tension of the ground shaft A is controlled at 2800N.

[0077] Embodiment 4-6

[0078] Same as Example 1, except that: in the weaving process, the tension of the upper shaft B is controlled at 420N, and the tension of the ground shaft A is controlled at 3000N.

[0079] The tension values ​​of the above-mentioned embodiments 4-1 to 4-6 exceed the preferred range. The selection of tension has the greatest impact on the speed and efficiency, which makes it difficult for weaving to proceed smoothly.

[0080] See data table 2 for specific impacts:

[0081] Table 2 Tension influence data

[0082]

[0083] Example 5-1 and Example 5-2

[0084] The same as Example 1, except that the warp yarn and the weft yarn use yarns of different finenesses, and Example 5-1, Example 5-2 and Example 1 are tested, wherein:

[0085] The air permeability is tested according to GB / T5453-1997;

[0086] The Crowe value was tested using ASTM D1518-14, Option 2;

[0087] The sense of three-dimensionality and refinement are evaluated by naked eye observation, with three people observing and taking the average value. The more *, the better the sense of three-dimensionality and refinement.

[0088] The test results are shown in Table 3 below:

[0089] Table 3 Test results

[0090]

[0091] The above shows that when the warp yarn fineness is higher than the weft yarn, the fineness of the fabric will be improved, but the three-dimensional effect of the fabric will be greatly reduced. When the warp yarn fineness is lower than the weft yarn, the three-dimensional effect of the fabric will be better, but the fineness of the fabric will be poor. Therefore, when the warp yarn and weft yarn fineness are the same, the best effect can be achieved.

[0092] Example 6

[0093] Same as Example 1, except that the empty reed does not show the plain weave of the lower layer. Figure 5 As shown in the figure: On the basis of the original non-hollow reed, the circled tissue is removed to achieve the hollow reed effect. If the plain weave is also hollowed out, a gap is formed, the air permeability increases, resulting in a decrease in warmth retention.

[0094] The test results of Example 1 and Example 6 are shown in Table 4 below:

[0095] Table 4 Test results of Example 1 and Example 6

[0096]

[0097] Comparative Example 1

[0098] Same as Example 1, except that: the connection method is conventional, such as Figure 6 As shown, the circled part is the difference in the connection points:

[0099] The joining point method of Example 1 is point-to-point joining. The upper and lower layer joining points are selected to be joined with the lower layer plain warp points in a "bottom-to-top" manner when the twisted warps are twisted, and a diamond-shaped joining arrangement is adopted, and the position is hidden under the twisted warps of the gauze. This joining method can better conceal the joining points and make the cloth surface look smoother.

[0100] In the binding method of Example 1, the binding points are exposed, similar to the displacement of yarns, making the fabric surface look uneven and unrefined.

[0101] The left side is the concealed connection method of Example 1, and the right side is the exposed connection method of Example 1. The advantages of concealed connection are: the connection point is not visible on the surface, and it is reflected in the actual object that there will be obvious concave points at the connection position of the upper and lower layers.
