Description

Technical Field

[0001] This invention relates to the field of textile fabric weaving, and in particular to a method for weaving textile fabrics with reflective warning function. Background Technology

[0002] Currently, due to the accelerated pace of technological modernization, the frequency of outdoor nighttime operations is increasing. Existing reflective textile materials require post-processing to laminate another reflective material onto the fabric to achieve reflectivity. For example, Chinese patent application number CN202222201716.0, publication number CN217917147U, entitled "A Reflective Fabric," discloses a reflective fabric comprising a skin-friendly layer, a carbon fiber layer, an elastic layer, a hot melt adhesive layer, a support layer, and a protective layer. Grooves are formed on the upper surface of the hot melt adhesive layer, and glass microspheres are placed inside these grooves. While the interaction between the glass microspheres and the grooves enables the fabric to reflect light, the reflective layer of this composite fabric exhibits unsatisfactory washability and abrasion resistance, and the additives used in the reflective material also have environmental performance defects. Therefore, developing a textile fabric with nighttime reflective effects and safety warning functions is particularly important. Summary of the Invention

[0003] The purpose of this invention is to provide a weaving method for textile fabrics with reflective warning function, which can solve the problems of reflective textile fabrics being not washable, not wear-resistant, and causing a lot of pollution.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a method for weaving a textile fabric with reflective warning function, comprising the following steps:

[0005] Step S1: Jacquard functional layer through cross-shifting and pressing of yarn using a comb: The raw material is reflective yarn, which is woven into various patterns and textures using a comb-and-jacquard method;

[0006] Step S2: Using double Jacquard combing to form a jacquard functional layer on the base fabric: Patterns that are not restricted by the track are woven in the form of Jacquard combing. The raw materials are polyester filament or irregular yarn. The three-dimensional, planar and mesh structures are formed by the combination of thick structure, thin structure and mesh structure. Different patterns are woven by combining and changing several structures such as satin, velvet, flat and perforated.

[0007] Step S3: Forming loop functional layers through double ground comb bars: The raw materials used are polyester filament or elastic yarn, and the double ground comb bars are woven with straight chain, variable chain, warp flat, double warp, and warp segment double ground comb structures respectively;

[0008] Step S4: Reinforce and stretch functional layer through ground comb weft insertion: The ground comb guides the yarn to act as needle back padding yarn, which is reinforced with filament or elastic yarn, or stretched with spandex.

[0009] Furthermore, step S1 further comprises: each weaving trajectory of the jacquard comb is woven in the warp direction, and each weft column is moved laterally by a small distance, with a single lateral movement distance between 0 and 2 cm, and the total cumulative lateral movement within the cycle not exceeding 20 cm.

[0010] Furthermore, in step S1, the yarn feeding method of the patterned yarn comb is to fully thread the patterned needles, with a warp feed rate of 2500mm / rack.

[0011] Furthermore, in step S2, the Jacquard comb is threaded in a full-length manner, using polyester filament or profiled yarn between 40D and 150D, with a warp feed rate of 1000-3000mm / rack, and the base padding yarn numbers are 0-1 / 2-1 / / , 1-0 / 1-2 / / or 0-1 / 3-2 / / , 1-0 / 2-3 / / .

[0012] Furthermore, in step S3, the yarn feeding method of the double-ground comb is full feeding, the raw material is polyester filament or elastic yarn between 40D and 150D, the warp feed is 300-2000mm / rack, and the basic padding yarn number is 1-0 / 0-1 / / .

[0013] Furthermore, step S4 further includes: when the ground comb guide yarn is used as needle back padding yarn, it is combined with the looped ground comb layer in the warp direction to create a regular mesh structure with a one-through-one-open or one-through-three-open yarn threading method; or when the ground comb guide yarn is used as needle back padding yarn, the yarn threading method is full threading, and the basic padding yarn code follows 1-1 / 0-0 / / or 0-0 / 1-1 / / , combined with filament or elastic yarn for longitudinal reinforcement; or when the ground comb guide yarn is used as needle back padding yarn, it is combined with spandex for longitudinal elasticity; or when the ground comb guide yarn is used as needle back padding yarn, the basic padding yarn code follows 3-3 / 0-0 / / or 0-0 / 3-3 / / , combined with raw materials of 100D or above for thickening and light blocking; or when the ground comb guide yarn is used as needle back padding yarn, it is combined with spandex for weft elasticity.

[0014] Furthermore, in step S4, the yarn feeding method of the ground comb is full feeding, and the warp feed is 300-2000mm / rack.

[0015] The beneficial effects of this invention are as follows: Compared with the prior art, this invention provides a method for weaving an environmentally friendly textile fabric with reflective warning function in one piece. This method enables the fabric to simultaneously possess excellent wash fastness, rubbing fastness, and other excellent properties such as easy degradation, environmental friendliness, and recyclability. It enables the textile material with warning function to be woven into one piece, resulting in a stable and robust structure. It exhibits excellent physical properties such as wash fastness, rubbing fastness, tear resistance, and burst resistance. The patterns with warning function are diverse and widely applicable to clothing, footwear, furniture, fire warnings, advertising packaging, and other fields. Attached Figure Description

[0022] The invention will now be further described with reference to the accompanying drawings.

[0023] Please see Figures 1 to 6 The present invention provides an embodiment: a method for weaving a textile fabric with reflective warning function, comprising the following steps:

[0024] Step S1: Using the lateral shifting and pressing of the yarn through the patterned yarn combing jacquard functional layer 1: using reflective yarn as the raw material, various patterns and textures are woven in the form of patterned yarn combing jacquard; through the lateral shifting and pressing jacquard functional layer 1, combined with reflective yarn material, various patterns and textures with a strong three-dimensional effect are formed on the top layer of the fabric by the weaving of reflective yarn, and the reflective function is provided by this weaving layer.

[0025] Step S2: Using double Jacquard combing of the base fabric to form a jacquard functional layer 2: Weave patterns that are not restricted by the track in the form of Jacquard combing. The raw materials are polyester filament or foreign yarn. Weave a three-dimensional, flat and mesh structure formed by the combination of thick structure, thin structure and mesh structure. Combined with Jacquard jacquard patterns that can be changed at will, the jacquard patterns can be varied. By combining and changing several structural changes such as satin, velvet, flat and perforated, different patterns such as numbers, letters and logos can be woven. The front and back Jacquard layers may also be combined with different colored yarn raw materials to form a special color and hand feel style.

[0026] Step S3: Using double-comb yarns to form loop functional layer 3: The raw material is polyester filament or elastic yarn. Each of the two combs weaves a straight chain, varied chain, warp plain, double warp, or warp segment double-comb structure. The two loop-forming combs can each weave a straight chain, varied chain, warp plain, double warp, or warp segment structure, or they can be used together to weave loop-forming, hexagonal mesh, and other double-comb structures. Combined with yarns of different thicknesses and shapes, the resulting base fabric is exceptionally strong, with superior physical properties such as abrasion resistance, folding resistance, tear resistance, and burst resistance. The two loop-forming combs can also be combined with different loop-forming structures, using unidirectional loop reinforcement and counter-directional loop complementation to improve different physical property requirements.

[0027] Step S4: Reinforce and stretch functional layer through ground comb weft insertion: The ground comb guides the yarn to act as needle back padding yarn, which is reinforced with filament or elastic yarn, or stretched with spandex.

[0028] The four functional layers—the jacquard layer 1 (combed yarn pressing), the jacquard layer 2 (double Jacquard comb forming loops), the jacquard layer 3 (double ground comb forming loops), and the ground comb reinforcement and elasticity layer 4—are sequentially woven into the knitting needles to complete one vertical and horizontal row of knitting. After all the horizontal row elements of a pattern cycle are woven, they are combined together to form a complete design pattern that repeats highly.

[0029] Please continue reading. Figures 1 to 6 As shown, in one embodiment of the present invention, step S1 further comprises: each patterned yarn of the jacquard comb is woven in the warp direction, and each weft row is moved laterally by a small distance, with a single lateral movement distance between 0-2cm, and the total cumulative lateral movement within the cycle not exceeding 20cm. Multiple patterned yarns can be formed independently or pieced together like a jigsaw puzzle to weave the pattern required according to the design drawing. Compared with the traditional weft-inserted jacquard comb, the advantage of the jacquard comb is that its yarns are woven into the base fabric at both ends, and the middle part is not held in the loop by the warp-knitted comb chain, so it can stand on the base fabric in a three-dimensional form. With the effect of reflective yarn, it can present a larger angle of reflection.

[0030] Please continue reading. Figures 1 to 6As shown, in one embodiment of the present invention, the yarn feeding method of the patterned yarn comb in step S1 is full threading of the patterned needle, and the yarn used is P-DTY300D / 36F YX1118 silver-gray reflective yarn with a feed rate of 2500mm / rack.

[0031] Please continue reading. Figures 2 to 3 As shown, in one embodiment of the present invention, the Jacquard comb in step S2 is threaded in a full-thread manner, using polyester filament or profiled yarn between 40D and 150D, with a warp feed of 1000-3000mm / rack and a base padding yarn number of 0-1 / 2-1 / / , 1-0 / 1-2 / / or 0-1 / 3-2 / / , 1-0 / 2-3 / / . Preferably, the yarn used is P-DTY150D / 36F BR low-elastic twisted yarn, with a warp feed of 2226mm / rack and a base padding yarn number of 0-1 / 2-1 / / .

[0032] Please continue reading. Figures 1 to 6 As shown, in one embodiment of the present invention, the yarn feeding method of the double-bottom comb in step S3 is full feeding, using polyester filament or elastic yarn between 40D and 150D, with a warp feed rate of 300-2000mm / rack and a base padding yarn number of 1-0 / 0-1 / / . Preferably, the raw material used is P-FDY100D / 36F BR high-strength yarn, with a warp feed rate of 1420mm / rack and a base padding yarn number of 1-0 / 0-1 / / .

[0033] Please continue reading. Figures 1 to 6 As shown, in one embodiment of the present invention, step S4 is further described as follows: when the ground comb guide yarn is used as needle back padding yarn, it is combined with the looped ground comb layer woven in the warp direction to create a regular mesh structure with a one-through-one-open or one-through-three-open yarn threading method; or when the ground comb guide yarn is used as needle back padding yarn, the yarn threading method is full threading, and the basic padding yarn code follows 1-1 / 0-0 / / or 0-0 / 1-1 / / , combined with filament or elastic yarn for longitudinal reinforcement; or when the ground comb guide yarn is used as needle back padding yarn, it is combined with spandex for longitudinal elasticity; or when the ground comb guide yarn is used as needle back padding yarn, the basic padding yarn code follows 3-3 / 0-0 / / or 0-0 / 3-3 / / , combined with raw materials of 100D or above for thickening and light blocking; or when the ground comb guide yarn is used as needle back padding yarn, it is combined with spandex for weft elasticity.

[0034] Please continue reading. Figure 5 As shown, in one embodiment of the present invention, the yarn feeding method of the ground comb bar in step S4 is full feeding, and the warp feed is 300-2000mm / rack. Alternatively, the additional elasticity function can be omitted as needed. Specific Implementation Example 1:

[0036] 1. Figure 4The layer shown is the reflective yarn pattern comb transverse pressing jacquard functional layer 1.

[0037] Compared to traditional weft-inserted combs, this functional layer has the advantage that its yarns are woven into the base fabric at both ends, and the middle part is not held in the loop by the warp-knitted comb chain. Therefore, it can stand on the base fabric in a three-dimensional form. With the effect of reflective yarn, it can present a wider angle of reflection.

[0038] Each thread in the jacquard weave is woven in the warp direction, but it can make small lateral movements in each weft direction, with a single lateral movement distance between 0-2cm and a total cumulative lateral movement of no more than 20cm within the cycle. Multiple threads can be woven independently or pieced together like a jigsaw puzzle to create the pattern required by the design.

[0039] The reflective yarn material is P-DTY300D / 36F YX1118 silver-gray reflective yarn. One roll of fabric requires 21 yarns to be hung on the yarn rack. Yarn threading is done with the needle fully threaded. The basic yarn padding number is 0-1 / 1-0 / / before the needle. The changes accumulate in each horizontal row, with a single horizontal movement distance between 0-2cm, and the total cumulative horizontal movement within the cycle not exceeding 20cm. The yarn padding number is a comb chain block file exported from WKCAD, which is converted into jacquard horizontal movement information through the textile machinery system.

[0040] 2. Figure 4 The layer shown is the double Jacquard comb-shaped jacquard functional layer 2.

[0041] This functional layer can be woven in a jacquard pattern without being restricted by the track. The raw material is P-DTY150D / 36F BR low-elastic twisted yarn. Each low-elastic yarn is passively fed through the yarn frame, which can eliminate the tension limitation required for tension balance in segmented active warping. Through the combination and variation of several structural variations such as satin, velvet, plain, and perforated, patterns such as numbers, letters, and logos can be woven together.

[0042] Jacquard raw material is P-DTY 150D / 36F BR low elastic twist, warp feed: 2226mm / rack, yarn threading method: full threading, warp feed method: passive warp feed on yarn frame, padding number: 0-1 / 2-1 / / .

[0043] 3. Figure 6 The blue yarn shown represents the double-layered looped functional layer 3. The double-layered looped yarn is used in conjunction to weave a double-braided chain bottom mesh.

[0044] The yarn material is P-FDY100D / 36F BR high-strength yarn, with a warp feed rate of 1420mm / rack, a full-length threading method, a segmented warp beam active warp feed method, and a padding number of 1-0 / 0-1 / / .

[0045] 4. Weft-insulated and reinforced functional layer. This product does not require reinforcement and is not equipped with additional reinforcement.

[0046] Under electrical control, the machine's needle bed, driven by cams, sequentially weaves four functional layers—the patterned yarn guide bar horizontal movement for jacquard weaving, the base fabric double Jacquard guide bar loop weaving, the double ground guide bar loop weaving, and the ground guide bar weft insertion reinforcement and elasticization—into the needles, completing one longitudinal and transverse weaving process. After all the transverse movement elements in a pattern cycle are woven, they are combined together to form a complete, highly repeating design pattern.

[0047] The above description is only a preferred embodiment of the present invention and should not be construed as a limitation of this application. All equivalent changes and modifications made in accordance with the scope of the patent application of the present invention should be covered by the present invention.
