In addition, the present invention provides examples of various specific processes and materials, but one of ordinary skill in the art may recognize applications of other processes and/or uses of other materials.
The invention provides a multilayer woven fabric which is formed by interweaving warp yarns and weft yarns; the warp yarns comprise first warp yarns and second warp yarns, and the weft yarns comprise first weft yarns, third weft yarns and second weft yarns;
the multilayer woven fabric comprises a pattern tissue and a fixed tissue; the pattern structure is set to be more than 1; the fixed tissues are distributed along the edges of the pattern tissues to separate the pattern tissues;
the pattern structure is divided into three layers, first warp yarns and first weft yarns are interwoven into a surface layer, the first warp yarns and second warp yarns are not interwoven with third weft yarns to form a middle floating layer, and the second warp yarns and the second weft yarns are interwoven to form a bottom layer;
the fixed structure is a layer and is formed by interweaving a first warp yarn, a second warp yarn, a first weft yarn, a third weft yarn and a second weft yarn together.
Specifically, the decorative pattern plays a decorative pattern role, the fixing pattern plays a connecting and fixing role, and different decorative patterns are separated. The multilayer weaving fabric can be provided with more than 1 pattern structure; the patterns and the sizes of the pattern tissues can be produced by a jacquard according to requirements and are separated by a fixed tissue. The patterns of each pattern structure can be the same or different, and the sizes can be the same or different, so that the appearance of the cloth cover is more diversified. Each pattern can form independent complete patterns, for example, the patterns of the patterns are designed into star, flower, square or circular patterns; alternatively, a plurality of patterns may be combined to form a complete pattern, for example, by separating the fixed patterns, a first pattern forms the flower core pattern, and a second pattern forms the flower petal pattern, so that the first pattern and the second pattern can be combined to form a flower pattern, as shown in fig. 4. The surface layer of each pattern structure can adopt different interweaving structures, so that the patterns of the cloth surface are diversified, and different fabric styles can be shown even if the same pattern adopts different interweaving structures. The bottom layer of each pattern structure can also be designed with different interweaving structures, so that the reverse side of the multilayer woven fabric can have a design feeling. Likewise, the fixed tissue may be designed in different patterns and sizes as desired.
The decorative pattern is divided into a surface layer, a middle floating layer and a bottom layer, and the interweaving structures of the surface layer and the bottom layer are unlimited and can be adjusted according to needs. For example, the surface layer can adopt weave with the floating length of more than 1, such as 1/1 plain weave, 2/1 twill, 3/1 twill, 5 satin and the like; the bottom layer can adopt weave with the floating length of more than 1, such as 1/1 plain weave, 2/1 twill weave, 3/1 twill weave, 5 satin weave and the like; and the middle floating line layer is formed by combining full-latitude point tissues in proportion.
The surface layer and the bottom layer can be selected from different structures according to needs. The three layers of the surface layer, the middle floating layer and the bottom layer of the pattern structure are independent structures and are not completely closed to form a complete structure, so that the three layers of the structures need to be connected by fixing the structures to form the complete structure; and, through the distribution of fixed tissue along the edge of decorative pattern tissue, make the decorative pattern tissue enclose and close and form required pattern and size. The interweaving structure of the fixed tissue is not limited and can be adjusted according to the needs. The fixed weave may be 1/1 plain weave, 2/1 twill, 3/1 twill, satin weave, or other special weave. Preferably, the multilayer woven fabric is a denim fabric. The multilayer weaving fabric can be designed into different patterns to form fabrics of different styles, different styles can be achieved by changing the raw material selection of yarns, and a novel product with variable styles and strong stereoscopic impression is provided for the field of jean fabrics.
For example, in a preferred embodiment, the first weft yarn: a second weft yarn: first weft yarns: the third weft yarns can be woven in according to the ratio of 1:1:1:1, and the warp yarns are sequentially interwoven with the first weft yarns, the second weft yarns, the first weft yarns and the third weft yarns to form a surface layer, a bottom layer and a middle floating layer. In the pattern structure, the third weft yarns of the middle floating layer formed by the third weft yarns play a role of supporting the surface layer in the fabric, so that the surface layer can be raised to form a three-dimensional effect; moreover, the weaving amount of the first weft yarns is 2 times of that of the second weft yarns and the third weft yarns, and the weft density of the surface layer is higher than that of the middle layer and the bottom layer, so that the surface layer has a raised feeling and the three-dimensional effect is enhanced. Moreover, the warp and weft density of the surface layer is higher, and the wind-proof and warm-keeping performances can be improved. The yarns selected by the first warp yarns and the second warp yarns can be the same or different, when the first warp yarns and the second warp yarns are different, the proportion of the first warp yarns to the second warp yarns can be any, and different styles can be displayed on the cloth surface.
In the present invention, the raw material of the warp and weft is not particularly limited, and may be selected as needed. The warp and weft yarns can be pure cotton, cotton wool, cotton bale core or blended yarns. The warp and weft can be short fibers such as cotton, hemp, tencel, modal, viscose, wool, terylene, chinlon and the like, can also be long fibers (such as terylene and chinlon), can also be elastic core-spun yarns formed by taking elastic yarns as cores and short fibers or long fibers as outer wrapping fibers, and can also be core-spun yarns formed by taking long fibers as cores and short fibers as outer wrapping fibers.
Although the warp and the weft do not have special limitation on the raw materials of the yarns, different yarns also have different influences on the effect of the fabric, so that different cloth styles are brought. For example, when the weft yarn is non-elastic yarn, the fabric has more stereoscopic impression than the common fabric due to the special structure of the multilayer woven fabric. When the first weft yarns are elastic yarns, the multilayer woven fabric has a wrinkle feeling due to yarn shrinkage, and the three-dimensional effect is more obvious as shown in fig. 6, but the bottom layer has no wrinkle as shown in fig. 7, so that the fabric surface is flat and skin-friendly; preferably, the elasticity of the first weft yarns is larger than that of the third weft yarns, so that the contractibility of the fabric surface layer is larger than that of the bottom layer, the cloth surface is firmer due to contraction, the bottom layer is less contracted, the warp yarns and the weft yarns are not tightly interwoven, and the bottom layer is in contact with the skin of a human body, so that the human body feels soft, comfortable and skin-friendly when the fabric is worn. Therefore, other weft yarns can also be elastic yarns, so that the fabric has better elasticity and is more comfortable to wear.
The warp yarns are divided into a first warp yarn and a second warp yarn, and can be inelastic yarns or elastic yarns. The elasticity of the first warp yarn and the second warp yarn may be the same or different with respect to whether the yarns are elastic or not. When one weft yarn is elastic yarn, the first warp yarn or the second warp yarn can be elastic yarn, so that the fabric has a four-side elastic effect.
In the scheme of the invention, the yarn count range of the warp and the weft is not particularly required, when the warp is made of short fibers, the yarn count range of the warp can be 6-70S, and when the warp is made of filaments, the yarn count range of the warp can be 40D-600D; when the weft yarn is made of short fibers, the yarn count range of the weft yarn can be 6-70S, and when the weft yarn is made of filaments, the yarn count range of the weft yarn can be 40D-600D.
Although there is no special requirement for the yarn count of the warp and the weft, different weft yarn count combinations can also have different effects on the effect of the fabric. For example, when the yarn count of the third weft yarn is larger than that of the second weft yarn and the yarn count of the second weft yarn is larger than that of the first weft yarn, the first weft yarn has a small yarn count, the cloth pattern is fine and beautiful, and the windproof and warm-keeping effects are good, as shown in fig. 4-5 and fig. 10-11; the third weft yarn in the middle is thick, so that the effect of supporting the surface layer can be better achieved, the surface layer can be raised, and the three-dimensional effect is better; the second weft yarns are thick, and the bottom layer is low in warp and weft density, so that the bottom layer is fluffy and soft, and the hand feeling is comfortable.
When the yarn count of the first weft yarn is larger than that of the second weft yarn and the third weft yarn and the second weft yarn and the third weft yarn adopt elastic yarns, the shrinkage rate of the second weft yarn and the third weft yarn is larger than that of the first weft yarn, so that the surface layer of the fabric is convex, the wrinkle feeling is stronger, and the three-dimensional effect is better.
The density of the warp and weft yarns directly affects the tightness of the weave, and the warp density of woven fabrics can be 30-300/inch in general and the weft density can be 20-200/inch in general. The weft density of the surface layer is preferably 55-80/inch, and the warp density is preferably 90-120/inch; the weft density of the bottom layer is preferably 35-50/inch, the warp density of the bottom layer is preferably 60-90/inch, the larger the warp and weft yarn densities of the surface layer and the bottom layer are, the more compact the fabric interweaving is, the more air can be stored in the middle floating layer, the better the heat preservation performance of the fabric is, and meanwhile, the warp and weft yarn densities in the range can make the fabric grains clearer.
The invention also provides a weaving method of the multilayer woven fabric, which comprises the following steps:
1. the warp yarns of a plurality of systems and the weft yarns of a plurality of systems are adopted for configuration, a cloth cover pattern is designed, and a pattern structure chart of a decorative pattern and a fixed structure is designed according to the cloth cover pattern.
2. Selecting the specification of the yarn and determining the color matching circulation of the warp and weft yarns.
3. The drafting sequence of the warp yarns and the number of insertions per dent are designed.
4. Weaving with a jacquard machine:
weaving on a loom: the fabric is woven by a jacquard machine, and the speed of the weaving machine is 380-400 r/min.
Opening time: the shedding time is early, the wrap angle of the warp yarns to the weft yarns is large during beating-up, and the weft yarns are easy to tighten. The weft density of the fabric is high, the fabric needs to be opened early, and the opening time is determined to be 318-322 degrees.
The time of entering the sword: the rapier feeding time of the weft feeding rapier is 60-65 degrees, and the rapier feeding time of the weft splicing rapier is 65-70 degrees. The rapier feeding time of the rapier loom has great influence on the production of woven fabrics, the rapier feeding time is early, as the effective height of a shed is small, warp yarns are easily broken by a rapier head or star jump defects are formed, the rapier feeding time is late, the running speed of the rapier head and a rapier belt can be increased under the condition of the same rotating speed of the loom, the loss of machine materials can be increased, and the production cost is increased. The fabric has better shed definition due to the use of a medium back beam height and high tension process, and can select earlier sword entering time.
And (3) quitting the sword time: the time for quitting the sword is 315-325 degrees. The time for the weft receiving sword to exit the shed is the same as the opening time, namely the weft yarn is released by the weft receiving sword and clamped by the warp yarn at the same time, so that the weft weaving shrinkage is prevented.
The number of the waste edge yarns is 12 on each side, and the release length of the weft yarn is the sum of the right waste edge yarn and 2-3 cm.
Height of the back beam: the back beam height is zero scale, and the back beam with medium height is selected. The weft density is small, the weft is easy to tighten, and a high back beam process is not needed. One advantage of using a medium height back beam is: the difference of the warp tension of the upper layer and the lower layer is small, and the height of the middle back beam is clear and beneficial to the shed on the premise of meeting the requirement of beating-up.
And (3) loading tension: the warp is single yarn, the machine tension can be controlled greatly, the machine tension is large, and the shed is clear and beneficial. The upper machine tension is controlled at 260-290 kg.
The present invention is further illustrated by the following specific examples.
