[0014] As a kind of technical scheme of improvement, the corresponding proportions of each layer of warp 1, warp 2 and warp 3 of the warp yarns are 5:2:5, and the corresponding proportions of each layer of weft 1, weft 2 and weft 3 of the weft yarns are 3:1:3.

[0015] As a kind of technical scheme of improvement, the warp 1, weft 1, warp 3 and weft 3 are pure cotton yarns.

[0016] As a kind of technical scheme of improvement, the speed of the loom during raising is 8-15 m / min, the P value is 0.1-1, and the CP value is 0.1-1. The P value refers to the speed of cloth feeding, and the CP value refers to the size of the napping force. The two parameters cooperate with each other to achieve the ideal napping effect.

[0022] Due to the adoption of the above technical solutions, the application has the following beneficial effects:

[0023] The organization of the stereoscopic relief multi-layer fabric of the application comprises jacquard multi-layer organization and base organization; the weaving process comprises the following steps: dividing ground warp into three layers: warp 1, warp 2 and warp 3; dividing weft into corresponding three layers: weft 1, weft 2 and weft 3; wherein, the intermediate layer warp 2 and weft 2 are both shrinkable yarn; warp 1 and weft 1, warp 2 and weft 2, warp 3 and weft 3 are respectively interwoven into the upper, middle and lower three layers of the jacquard multi-layer organization; warp 1 and warp 3 are respectively interwoven with weft 1 and weft 3 to form the base organization, warp 2 falls when meeting weft 1 and rises when meeting weft 3, so as to fix warp 2 and weft 2 in the interlayer of the base organization; the woven grey cloth is first napped on both sides, then is treated by overflow machine high temperature finishing, and is loose dried after free shrinkage, so as to obtain the stereoscopic relief multi-layer fabric. The multi-layer fabric of the application adopts unconventional dyeing and finishing process, and the dyeing and finishing is first napping on the grey cloth. Since the intermediate layer is shrinkable yarn, the intermediate layer of the multi-layer organization can freely shrink in the process of overflow machine high temperature finishing, and the shrinkage rate is large, so as to pull the upper and lower two layers of organization into a stereoscopic wrinkle shape. The wrinkle can be designed in size according to needs, and the pattern and the base organization are reasonably matched, so as to form a cloud shape, a pattern shape, a checkered shape, a heart shape or other stereoscopic shapes required. Since the base single layer is weft, the shrinkable yarn fixed in the interlayer of the base organization is not easy to shrink due to the tight organization, and the shrinkage rate is small. This kind of organization structure makes the base napping deeper than the jacquard part, and the napping feeling is strong, so as to make the pattern effect more prominent. Finally, the cloud relief fabric is realized, and the pattern boundary is stereoscopic and prominent. Moreover, the fabric is given a fluffy and soft hand feeling, and is comfortable and beautiful. The fabric does not need to be divided into front and back sides, and the effects on both sides are consistent after napping, so the fabric can be used on both sides. The fabric is suitable for a blanket, and can be used in many places such as home and office. It meets the current consumer's pursuit of individualization and meets the differentiated market demand, so the market prospect is broad.

[0024] The base organization of the application is interwoven with warp 1, warp 3 and weft 1 to form 1 / 3 weft broken twill, and is interwoven with warp 1, warp 3 and weft 3 to form 3 / 1 warp broken twill, and the interweaving rule of weft 2 is the same as that of weft 3; warp 2 is below weft 1 and above weft 3, and warp 2 is hidden in the interlayer of the base organization, so that weft 2 is hidden in the B side, the B side is faintly visible, the A side cannot be seen, and is completely hidden after napping, without affecting the napping effect, and the effects on both sides are consistent, so the fabric can be used on both sides.

[0025] The warp 1, warp 3 of the application are 40S / 2C yarns; the warp 2 and weft 2 are 450D polyester shrink yarns; the weft 1, weft 3 are 20S / 2C yarns, and the corresponding proportions of each layer of the warp yarns warp 1, warp 2 and warp 3 are 5:2:5, and the corresponding proportions of each layer of the weft yarns weft 1, weft 2 and weft 3 are 3:1:3; such yarn selection and yarn proportion ensure that the surface layer of the fabric has large density, and the ply yarn can better cover the polyester shrink yarn, avoiding that the upper and lower layers have small proportion and small density, and the polyester shrink yarn is easily exposed to affect the appearance effect and wearing comfort.

[0026] The temperature of the high-temperature finishing of the overflow machine after weaving of the application is 105-120 DEG C, which is 20 DEG C higher than the conventional finishing temperature, and is more beneficial to the shrinkage of the intermediate shrinkage layer at high temperature, and improves the three-dimensional effect.

DETAILED DESCRIPTION

[0033] The application will be further described below in combination with the drawings and examples. It should be understood that these examples are only used for illustrating the application and are not used for limiting the scope of the application. In addition, it should be understood that after reading the content taught by the application, those skilled in the art can make various modifications or changes to the application, and these equivalent forms also fall within the scope defined by the appended claims of the application.

[0034] Example 1

[0035] Yarn preparation: the ground warp is divided into three layers: warp 1, warp 2 and warp 3, and the weft yarn is divided into three layers: weft 1, weft 2 and weft 3; wherein the warp 1, warp 3 are 40S / 2C pure cotton yarns; the warp 2 and weft 2 are 450D polyester shrink yarns; the weft 1, weft 3 are 20S / 2C pure cotton yarns;

[0036] Fabric weaving: as shown in Figure 1 and Figure 2 , the corresponding proportions of each layer of warp 1, warp 2 and warp 3 of the warp yarn are: 1, 3, 1, 3, 1, 2, 3, 1, 3, 1, 3, 2, and the corresponding proportions of each layer are: 5:2:5; the corresponding proportions of each layer of weft 1, weft 2 and weft 3 of the weft yarn are: 1, 3, 1, 3, 1, 3, 2, and the corresponding proportions of each layer are: 3:1:3; warp 1 and weft 1, warp 2 and weft 2, warp 3 and weft 3 are interwoven into the upper, middle and lower three layers of plain weave of the jacquard multi-layer weave respectively; warp 1 and warp 3 are interwoven with weft 1 to form 1 / 3 weft face broken twill, warp 1 and warp 3 are interwoven with weft 3 to form 3 / 1 warp face broken twill, and weft 2 is interwoven with weft 3, warp 2 falls when meeting weft 1 and rises when meeting weft 3, that is, the second layer of polyester shrink yarn warp is under the first layer of weft and above the third layer of weft, and warp 2 is not exposed in the middle, which is interwoven into the ground weave.

[0037] The fabric is woven on a single-warp beam loom with a stripe pulling shaft to prevent the warp from loosening. When weaving, the warp stopper is moved backward, the shedding is increased, the tension of the upper thread is increased, and an iron block is added to the middle position of the warp stopper to press the warp stopper and reduce the shaking. The height of the warp stopper is adjusted to 0 and the depth is -1.

[0038] Fabric post-processing: the woven fabric is first napped on both sides, and then subjected to high-temperature finishing on an overflow machine; the temperature of the high-temperature finishing is 110°C, the fabric is allowed to shrink freely, and then is dried in a loose manner to obtain the multi-layer fabric with the three-dimensional embossing effect.

[0039] Napping is carried out on a lafer napping machine composed of four large tin forests, each large tin forest has 12 pairs of napping rollers, and the following two napping processes can be used:

[0040] Napping process 1: speed 8 m / min, P value 0.2, CP value 0.3, three forward and one reverse threading mode, the nap of the front side is slightly better than that of the back side, and the contact area of the front and back sides with the skin is different.

[0041] Napping process 2: speed 10 m / min, P value 0.1, CP value -0.1, two forward and two reverse threading mode, the naps of the front and back sides are the same, and both sides can be used.

[0042] Comparative example 1

[0043] As shown in Figure 3 , Figure 4 , the difference between comparative example 1 and example 1 is that warp 2 and weft 2 are 300D polyester low-elasticity yarn, weft 1 and weft 3 are 8S / C pure cotton yarn, and the corresponding arrangement of the three layers of warp yarn is: 1, 3, 1, 2, 3, 1, 3, 2, and the corresponding proportions of each layer are: 3:2:3.

[0044] According to the yarn design and the arrangement and proportion of each layer, the surface of the woven product is sparse and has small density, and when the pile is grabbed, the polyester low-elasticity filament in the interlayer is easily grabbed to cause the entanglement of the fluff to form a cotton ball.

[0045] Double warp beam weaving is adopted, the ground warp is pure cotton yarn, and the pile warp is polyester low-elasticity filament. Since the polyester low-elasticity filament is distributed less on the single-axis pile warp beam, the slackening amount is fast, the breakage is prevented, and sizing is performed before weaving, but the high-temperature resilience of the subsequent low-elasticity filament is affected, resulting in that the relief effect of the fabric after the post-processing raising is not obvious.

[0046] The raising process is as follows: the speed is 15 m / min, the P value is 1.2, the CP value is 1.4, the three normal and one reverse weaving mode is adopted, the fluff on the fabric surface is electrostatically twisted after raising, and the pile grabbing is uneven, which affects the pile feeling of the fabric surface.

[0047] Comparative Example 2

[0048] The difference between Comparative Example 2 and Example 1 is that the warp 2 and weft 2 are 600D polyester low-elasticity filament.

[0049] According to the yarn design and the arrangement and proportion of each layer, the surface of the woven product is sparse and has small density, and when the pile is grabbed, the polyester low-elasticity filament in the interlayer is easily grabbed to cause the entanglement of the fluff to form a cotton ball.

[0050] Double warp beam weaving is adopted, the ground warp is pure cotton yarn, and the pile warp is polyester low-elasticity filament, and no sizing is performed. Since the polyester low-elasticity filament has a fast warp feeding amount, the yarn is not in a straight state, and even if the yarn is shrunk in a curved state, the surface shrinkage cannot be pulled, which affects the relief effect of the fabric after the post-processing raising, the pattern and the bottom are flat, and there is no concave-convex effect, and the aesthetic effect cannot be achieved.

[0051] The raising process is as follows: the speed is 15 m / min, the P value is 0.5, the CP value is 0.8, the three normal and one reverse weaving mode is adopted, the fluff on the fabric surface is electrostatically twisted after raising, and the pile grabbing is uneven.
