Description

Technical Field

[0001] This utility model relates to the field of warp knitting plush technology, and in particular to a simulated warm rabbit fur fabric and its production system. Background Technology

[0002] Before the advent of synthetic fibers, the artificial fur industry was highly developed. People used animal hair such as wool, mohair, or alpaca to weave fashionable artificial fur fabrics, and through various finishing processes, they were given a certain luster and other properties. However, due to the high cost of animal hair raw materials, only expensive garments could be produced, and the ironing and calendering processes often used formaldehyde solvents harmful to human health, making washing difficult. With the development of the fiber industry, animal hair in artificial fur raw materials was gradually replaced by synthetic fibers. Furthermore, with advancements in textile technology, the simulation of animal fur fabrics has become increasingly sophisticated. Different colors and patterns can be created through dyeing, embossing, and shearing processes. Garments made from these animal fur fabrics are less bulky than real fur, are lighter, offer more diverse styles, are fashionable and modern, and are more affordable than real fur, making them popular with ordinary consumers. Moreover, with various animal protection activities initiated by animal protection organizations, more young people are choosing clothing made from simulated animal fur instead of real fur to avoid harming animals.

[0003] In recent years, existing rabbit fur has been found to have poor warmth retention. Although it may look similar to rabbit fur, its warmth retention is difficult to guarantee. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, this application provides a simulated warm rabbit fur fabric and production system to solve the problem that existing rabbit fur has poor warmth retention. Although it can resemble rabbit fur in appearance, its warmth retention is difficult to guarantee.

[0005] To address the aforementioned technical problems, this application provides the following technical solutions.

[0006] In a first aspect, this application provides a simulated thermal rabbit fur fabric, the simulated thermal rabbit fur fabric comprising: A close-fitting layer, wherein the close-fitting layer is woven from a fine denier nylon or polyester filament woven fabric; A thermal insulation layer is provided on the body-hugging layer, and the thermal insulation layer has multiple air rings or arched structures inside; A fleece layer, wherein the fleece layer is located on the side of the insulating layer away from the inner layer, and the fleece layer is made of imitation rabbit fur; The air ring or arched structure is used to slow down the airflow speed from the inner layer to the fleece layer, so as to reduce heat loss.

[0007] Furthermore, the insulating layer comprises warp yarns and weft yarns, which are cross-woven to form the arched structure.

[0008] Furthermore, the pile layer has short pile and long guard hairs, with the short pile and long guard hairs interlaced and clustered on the base fabric of the pile layer, and the density of the short pile is greater than the density of the long guard hairs.

[0009] Furthermore, the short down is made of fine denier polyester or acrylic short fiber yarn as terry yarn, to simulate the hair follicle density per unit area of ​​rabbit fur.

[0010] This application also proposes a production system for producing the aforementioned simulated warm rabbit fur fabric, comprising: frame; Central control module, the central control module being mounted on the rack; A feeding module is located at the end of the frame; A multi-sensor detection module is mounted on the frame and is used to receive the fabric transmitted by the feeding module and detect the surface contour, pile height, density, wrinkles or unevenness of the fabric. A laser cutting module is mounted on the frame, and a multi-sensor detection module is located between the feeding module and the laser cutting module. The feeding module, the multi-sensor detection module, the laser cutting module, and the central control module are electrically connected. The multi-sensor detection module detects substandard fabric and sends a first alarm signal to the central control module. Based on the first alarm signal, the central control module controls the laser cutting module to cut the substandard fabric area.

[0011] Furthermore, the multi-sensor detection module includes: A 3D line scan laser profilometer is mounted on a frame. A platform is located on the frame and directly below the 3D line scan laser profilometer. The recognition area of ​​the 3D line scan laser profilometer covers the platform. The fabric is transferred to the placement platform via the feeding module. The 3D line-scanning laser profiler scans the surface profile, pile height, density, wrinkles, or unevenness of the fabric in real time and sends corresponding signals to the central control module.

[0012] Furthermore, the multi-sensor detection module also includes: A multispectral vision unit is mounted on the frame and located between the laser cutting module and the 3D line scan laser profilometer. The multispectral vision unit is used to detect the heat distribution of the fabric and send corresponding signals to the central control module.

[0013] Furthermore, the laser cutting module includes: The track unit, wherein the transmission direction of the track unit is from the feeding module to the multi-sensor detection module; A cutting unit, which is located on the track unit and close to the multi-sensor detection module; A protective cover unit is disposed on the frame, and the cutting unit is located inside the protective cover unit.

[0014] Furthermore, the track unit passes through the protective cover unit and is partially exposed outside the protective cover unit.

[0015] Furthermore, the protective cover unit is a transparent glass cover.

[0016] Compared with the prior art, the beneficial effects of this application are as follows: This application uses a close-fitting layer as the base layer. To improve warmth, the close-fitting layer can be made of high-density ultra-fine denier nylon or polyester filament woven fabric, ensuring high strength and good windproof performance. Alternatively, it can use blended yarns of high-count combed cotton, modal, or moisture-wicking and heat-generating fibers (such as EKS fibers). It is woven with a tight structure such as plain knit or fine rib to ensure the close-fitting layer is skin-friendly, comfortable, and moisture-wicking. To mimic the density and shape of rabbit fur, the outermost layer is a fleece layer, which is made to resemble rabbit fur. To mimic the warmth of rabbit fur, this application includes a warming layer in the close-fitting layer. The fleece layer is located on the side of the warming layer away from the close-fitting layer. The weaving structure of this warming layer has multiple air loops or arched structures, with slow-moving air within these air loops or arched structures. Specifically, during the weaving process of the warming layer, the yarn connecting the close-fitting layer and the fleece layer forms numerous three-dimensional air loops or arched structures. The air ring or arched structure is filled with slowly flowing air, effectively preventing heat loss. This application creates a simulated warm rabbit fur fabric by setting up a three-layer fabric structure with different functions: a close-fitting layer, a warming layer, and a fleece layer, effectively solving the problem of poor warmth retention in existing rabbit fur fabrics.

[0023] Before the advent of synthetic fibers, the artificial fur industry was highly developed. People used animal hair such as wool, mohair, or alpaca to weave fashionable artificial fur fabrics, and through various finishing processes, they were given a certain luster and other properties. However, due to the high cost of animal hair raw materials, only expensive garments could be produced, and the ironing and calendering processes often used formaldehyde solvents harmful to human health, making washing difficult. With the development of the fiber industry, animal hair in artificial fur raw materials was gradually replaced by synthetic fibers. Furthermore, with advancements in textile technology, the simulation of animal fur fabrics has become increasingly sophisticated. Different colors and patterns can be created through dyeing, embossing, and shearing processes. Garments made from these animal fur fabrics are less bulky than real fur, are lighter, offer more diverse styles, are fashionable and modern, and are more affordable than real fur, making them popular with ordinary consumers. Moreover, with various animal protection activities initiated by animal protection organizations, more young people are choosing clothing made from simulated animal fur instead of real fur to avoid harming animals.

[0024] However, in recent years, existing rabbit fur has been found to have poor warmth retention. Although it may look similar to rabbit fur, its warmth retention is difficult to guarantee.

[0025] like Figures 1-2 As shown, in view of the above, this application proposes a simulated warm rabbit fur fabric and production system, the simulated warm rabbit fur fabric comprising: a body-fitting layer 1, the body-fitting layer 1 being woven from fine denier nylon or polyester filament woven fabric; a warming layer 2, disposed on the body-fitting layer 1, the warming layer 2 having multiple air rings or arched structures 201 inside; and a fleece layer 3, the fleece layer 3 being disposed on the side of the warming layer 2 away from the body-fitting layer 1, the fleece layer 3 being simulated rabbit fur; wherein, the air rings or arched structures 201 are used to slow down the airflow speed from the body-fitting layer 1 to the fleece layer 3, so as to reduce heat loss.

[0026] In this embodiment, the inner layer 1 is used as the base layer. To improve the warmth retention, the inner layer 1 can be made of high-density ultra-fine denier nylon or polyester filament woven fabric, ensuring high strength and good windproof properties. Alternatively, it can be made of high-count combed cotton, modal, or moisture-wicking and heat-generating fibers (such as EKS fibers) blended yarn. It is woven with a tight structure such as plain knit or fine rib to ensure that the inner layer 1 is skin-friendly, comfortable, and moisture-wicking. To mimic the density and shape of rabbit fur, the outermost layer is a fleece layer 3, which is made of imitation rabbit fur. To mimic the warmth of rabbit fur, this application incorporates a thermal insulation layer 2 within the inner layer 1, and a fleece layer 3 on the side of the thermal insulation layer 2 away from the inner layer 1. The thermal insulation layer 2 features a weave structure with multiple air loops or arched structures 201 containing slowly flowing air. Specifically, during the weaving process of the thermal insulation layer 2, the yarns connecting the inner layer 1 and the fleece layer 3 are used to form numerous three-dimensional air loops or arched structures 201. These air loops or arched structures 201 are filled with slowly flowing air, effectively preventing heat loss. This application, by establishing a three-layer fabric structure with different functions—the inner layer 1, the thermal insulation layer 2, and the fleece layer 3—creates a simulated warm rabbit fur fabric, effectively solving the problem of poor warmth retention found in existing rabbit fur products.

[0027] like Figure 2 As shown, specifically, the insulating layer 2 includes warp yarns 202 and weft yarns 203, which are interwoven to form the arched structure 201. In this embodiment, to improve the warmth retention of the fabric, the insulating layer 2 of this application has warp yarns 202 and weft yarns 203 connecting the inner layer 1 and the fleece layer 3, and the warp yarns 202 and weft yarns 203 of the insulating layer 2 are interwoven to form the arched structure 201. During use, the arched structure 201 is filled with slowly flowing air, effectively preventing heat loss.

[0028] Specifically, the pile layer 3 has short pile 301 and long guard hairs 302. The short pile 301 and the long guard hairs 302 are interlaced and clustered on the base fabric of the pile layer 3, and the density of the short pile 301 is greater than the density of the long guard hairs 302. In this embodiment, the main purpose of the pile layer 3 is to imitate rabbit fur. Therefore, the pile layer 3 is clustered with short pile 301 and long guard hairs 302, wherein the short pile 301 is dense and the long guard hairs 302 have a lower density. The dense short pile 301 and the relatively small number of long guard hairs 302 form a double-layer structure. The process can be that the fabric of the pile layer 3 is woven by machine in one go to form a tightly connected "two-story" structure, thereby imitating rabbit fur.

[0029] Specifically, the short down 301 uses fine denier polyester or acrylic staple fiber yarn as the terry yarn to mimic the hair follicle density per unit area of ​​Rex rabbit fur. In this embodiment, in the specific process, ultra-fine denier polyester or acrylic staple fiber yarn imitating Rex rabbit fur can be used as the terry yarn. Through high-density brushing, brushing, and shearing processes, the down layer 3 forms a highly dense, neat, and soft layer of short down 301, simulating the appearance and feel of Rex rabbit fur.

[0030] like Figures 3-6 As shown, this utility model also proposes a production system 4 for producing and processing the aforementioned simulated warm rabbit fur fabric, comprising: a frame 41; a central control module 45 disposed on the frame 41; a feeding module 42 disposed at the end of the frame 41; and a multi-sensor detection module 43 disposed on the frame 41 for receiving the fabric transmitted by the feeding module 42 and detecting the surface contour, pile height, density, and wrinkles or unevenness of the fabric. A laser cutting module 44 is mounted on the frame 41, and a multi-sensor detection module 43 is located between the feeding module 42 and the laser cutting module 44. The feeding module 42, the multi-sensor detection module 43, and the laser cutting module 44 are electrically connected to the central control module 45. Based on the detection of substandard fabric by the multi-sensor detection module 43, a first alarm signal is sent to the central control module 45. The central control module 45 then controls the laser cutting module 44 to cut the substandard fabric area based on the first alarm signal. The specific structure of this simulated warm rabbit fur fabric is as described in the above embodiments. Since the production system 4 is applied to the production and processing of all the technical solutions of the above embodiments, it possesses at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated upon here.

[0031] Because the production process of simulated warm rabbit fur fabric is relatively complex, it is difficult to achieve a 100% pass rate for finished products. In the specific fabric cutting process, the simulated warm rabbit fur fabric needs to be cut, but identifying areas of substandard fabric is a significant industry challenge. For example, when cutting the simulated warm rabbit fur fabric according to a preset area or length, defects may exist, such as irregular surface contours, low pile height, low density, or wrinkles or unevenness. These substandard areas need to be cut off to ensure a 100% pass rate for subsequent batches of fabric pieces and reduce the defect rate of finished products. Therefore, the production system 4 proposed in this application includes a central control module 45, a feeding module 42, a multi-sensor detection module 43, and a laser cutting module 44. The central control module 45 is the control assembly of the production system 4. The feeding module 42 is used to place the rolled fabric, which is then conveyed to the laser cutting module 44. A multi-sensor detection module 43 is positioned between the feeding module 42 and the laser cutting module 44 to receive the fabric from the feeding module 42 and detect its surface contour, nap height, density, and any wrinkles or unevenness. Initially, if the fabric is deemed acceptable after detection by the multi-sensor detection module 43, the module sends a pass signal to the central control module 45. The central control module 45 pre-sets the cutting length of the fabric under the pass signal. Therefore, after the multi-sensor detection module 43 detects the fabric, it sends a pass signal to the central control module 45 and controls the laser cutting module 44 to cut the fabric to a predetermined length according to preset parameters. If the multi-sensor detection module 43 detects that the surface contour, pile height, density, wrinkles or unevenness of the fabric are unqualified, it sends a first alarm signal to the central control module 45, and the central control module 45 controls the laser cutting module 44 to cut the unqualified fabric area.

[0032] like Figure 3 As shown, specifically, the multi-sensor detection module 43 includes: A 3D line scan laser profilometer 431 is mounted on a frame 41. A platform 433 is located on the frame 41 and directly below the 3D line scan laser profilometer 431. The recognition area of ​​the 3D line scan laser profilometer 431 covers the platform 433. The fabric is transmitted to the placement platform 433 via the feeding module 42. The 3D line scanning laser profiler 431 scans the surface profile, pile height, density, wrinkles or unevenness of the fabric in real time and sends corresponding signals to the central control module 45.

[0033] In this embodiment, in front of the laser cutting module 44, a 3D line-scanning laser profilometer 431 scans the surface profile of the fabric on the placement platform 433 in real time, accurately measuring the pile height, density, and identifying wrinkles or unevenness caused by winding. After the 3D line-scanning laser profilometer 431 detects the fabric, it sends a pass signal to the central control module 45 and controls the laser cutting module 44 to cut the fabric to a predetermined length according to preset parameters. If the 3D line-scanning laser profilometer 431 detects that the surface profile, pile height, density, wrinkles, or unevenness of the fabric are unqualified, it sends a first alarm signal to the central control module 45, and the central control module 45 controls the laser cutting module 44 to cut the unqualified fabric area.

[0034] Specifically, the multi-sensor detection module 43 further includes: A multispectral vision unit 432 is disposed on the frame 41 and located between the laser cutting module 44 and the 3D line scan laser profilometer 431. The multispectral vision unit 432 is used to detect the heat distribution of the fabric and send corresponding signals to the central control module 45.

[0035] In this embodiment, because the simulated warm rabbit fur fabric has dense fluff, a multispectral vision unit 432 is added to accurately detect surface defects (such as color difference, stains) and material texture, as well as the fabric's heat distribution. The multispectral vision unit 432 has a high-resolution color camera and an infrared camera. The color camera is used to identify surface defects (such as color difference, stains) and material texture, while the infrared camera can detect the fabric's heat distribution, quickly detecting overheated areas (potential scorching risk) after cutting. Specifically, when the multispectral vision unit 432 detects that the fabric's heat distribution is unqualified, it sends a corresponding signal, such as a second alarm signal, to the central control module 45. The central control module 45 then controls the laser cutting module 44 to cut the unqualified fabric area.

[0036] Specifically, the laser cutting module 44 includes: Track unit 441, the transmission direction of track unit 441 is from the feeding module 42 to the multi-sensor detection module 43; Cutting unit 442, the cutting unit is located on the track unit 441 and close to the multi-sensor detection module 43; A protective cover unit 443 is disposed on the frame 41, and the cutting unit 442 is located inside the protective cover unit 443.

[0037] In this embodiment, the conveyor unit 441 is used to transport the fabric, the cutting unit 442 is a laser cutting blade used to cut the fabric, and the protective cover unit 443 covers the cutting unit 442 to protect the surrounding personnel. It can be understood that a two-dimensional moving platform can be set on the frame 41, and the cutting unit 442 can be placed on the two-dimensional moving platform. Based on the scanning data from the 3D line-scan laser profilometer 431, the cutting unit 442 dynamically adjusts its Z-axis focal length to ensure that the laser focus always falls on the position of the fabric to be cut, rather than the tip or middle of the pile, thereby obtaining a clear, unburnt cut edge.

[0038] Specifically, the track unit 441 passes through the protective cover unit 443 and is partially exposed outside the protective cover unit 443. In this embodiment, the protective cover unit 443 does not completely cover the track unit 441; the track unit 441 is partially exposed outside the protective cover unit 443, so that the fabric can be laid flat on the track unit 441 so that workers can check whether the cutting is accurate.

[0039] Specifically, the protective cover unit 443 is a transparent glass cover.

[0040] In this embodiment, in order to facilitate the observation of the operation of the laser cutting unit 442 by the staff, the protective cover unit 443 is preferably set as a transparent glass cover.

[0041] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
