Description

Technical Field

[0001] This invention relates to the field of fiber processing technology, and in particular to a method for producing multi-chamber flash temperature absorption and controllable tension acetate and triacetate fiber fabrics. Background Technology

[0002] Acetate and triacetate fibers are man-made fibers produced by the esterification reaction of cellulose and acetic anhydride. They possess a silky luster and soft hand feel while maintaining good strength and elasticity. Acetate and triacetate fibers have superior moisture absorption compared to many other man-made fibers, making them very popular in clothing and home textiles. Furthermore, their good light and heat resistance makes them widely used in decorative items such as curtains and tablecloths.

[0003] The production process of acetate and triacetate fibers is relatively environmentally friendly because it uses renewable cellulose as raw material, and byproducts from the production process can be recycled. These fibers can be enhanced through dyeing and printing processes, creating a variety of visually appealing effects. However, acetate and triacetate fibers also have some limitations; for example, they are not as easily biodegradable as natural fibers, which may have some environmental impact.

[0004] In general, acetate and triacetate fibers are multifunctional man-made fibers that occupy an important position in the textile industry due to their unique physical and chemical properties. With technological advancements and increased environmental awareness, the production and application of acetate fibers are constantly developing and improving.

[0005] Currently, the market offers a wide variety of mature acetate and triacetate fibers, including both staple and filament varieties. These fibers come in various finenesses, such as 35D / 9F, 55D / 15F, 75D / 20F, 100D / 26F, and 200D / 34F. They are available in both bright and dull finishes, twisted and untwisted varieties, and can be combined with PE in various ways, including ply-twisted, ply-twisted, and organically wrapped composites. Furthermore, multi-strand twisting of acetate and triacetate fibers with other yarns creates a slub-like texture.

[0006] To achieve a richer texture on the fabric, the reciprocating twisting of acetate and triacetate fibers is a common method. However, due to the poor strength, low production efficiency, high waste, and high cost of acetate and triacetate fibers, it is necessary to implement controllable deformation technology on the fibers to achieve a richer fabric texture. This will improve efficiency, reduce costs and quality risks, increase the richer fiber texture, and further enhance the texture of the fabric.

[0007] Acetate and triacetate fiber fabrics with a slub-like texture are primarily made using techniques that utilize the different fineness and twist of acetate and triacetate fibers compared to PE fibers. These techniques involve repeated twisting, and the composite technology of acetate and triacetate fibers with ordinary PE, shaped cross-section PE, or cationic PE. Due to their low breaking strength and inherent softness, acetate and triacetate fibers are prone to snagging and quality issues during processing, leading to breakage, losses, and high costs. The multiple processing steps further increase the processing risks of acetate and triacetate fiber fabrics. Given the sensitivity of acetate and triacetate fibers, shorter processing steps are preferable; therefore, multiple manufacturing processes should be avoided as much as possible to reduce the complexity of the composite process.

[0008] Therefore, a production method for multi-compartment flash temperature absorption color controllable tension acetate and triacetate fiber fabrics is proposed to solve or alleviate the above problems. Summary of the Invention

[0009] The purpose of this invention is to address the shortcomings of existing technologies by proposing a method for producing multi-compartment flash temperature absorption and controllable tension acetate and triacetate fiber fabrics.

[0011] A method for producing a multi-compartment, temperature-sensitive, color-absorbing, controllable tension acetate and triacetate fiber fabric includes the following steps.

[0012] For material preparation, the raw materials for acetate and triacetate fibers should have a coarse single fiber fineness (D) and a high fiber number (F).

[0013] The filaments are sequentially spun into the tubular channels through which acetate and triacetate fibers run via multi-chamber hot air jet nozzles.

[0014] Actively clamping tension-controllable rubber rollers stretch the tubular channel before and after, and generate traction differential speed to obtain multi-chamber flash temperature absorption color controllable tension acetate and triacetate fibers.

[0015] Multi-compartment flash temperature absorption controllable tension acetate and triacetate fibers are cut and processed according to cotton-type length, medium-length length, and wool-type length and blended with other materials. By utilizing the difference between coarse and fine denier, irregularly shaped yarns with axial changes due to differences in inertia are formed.

[0016] Different shaped yarns are woven to form multi-compartment flash temperature absorption color controllable tension acetate and triacetate fiber fabrics.

[0017] The finished product is produced by dyeing multi-chamber flash temperature absorption controllable tension acetate and triacetate fiber fabrics.

[0018] Preferably, the tubular channel has openings on both sides and is arranged at equal intervals along its long axis to form a semi-closed structure.

[0019] Preferably, the nozzles are connected in series inside the tubular channel, the nozzles are made of metal, and the lower part of the series nozzles is welded to the inner diameter of the tubular channel. The spacing of the nozzles is arranged in an arithmetic sequence of 1:3:5:7.

[0020] Preferably, the temperature of the nozzle is 165℃-185℃.

[0021] Preferably, the speed ratio of the actively clamping tension controllable rubber rollers located before and after the tubular channel is 0.1-0.5.

[0022] Preferably, the coarse D is 3-6D, and the multiple F is 9-34F.

[0023] Preferably, the multi-compartment flash temperature absorption color controllable tension acetate and triacetate fiber fabric is a woven fabric.

[0024] Preferably, the multi-compartment flash temperature absorption color controllable tension acetate and triacetate fiber fabric is a knitted fabric, and the knitted fabric uses multi-compartment flash temperature absorption color controllable tension acetate and triacetate fiber yarn covered with high shrinkage PE composite yarn.

[0025] The present invention has the following beneficial effects:

[0026] This invention solves the problems of difficult processing, low efficiency, high loss and high cost of acetate and triacetate fiber fabrics with slub style, while increasing the variability and possibilities of acetate and triacetate fiber fabrics. Attached Figure Description

[0027] Figure 1 This is a flowchart of the present invention. Detailed Implementation

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0029] A method for producing multi-compartment flash-temperature-absorbing, color-controllable tension acetate and triacetate fiber fabrics, such as Figure 1 As shown, it includes the following steps:

[0030] For raw material preparation, the single fiber fineness of acetate and triacetate fibers should be coarse (D) and have a high fiber number (F), with a coarse D of 3-6D and a high fiber number of 9-52F.

[0031] Air is injected sequentially through a multi-chamber hot air jet nozzle into a tubular channel in which acetate and triacetate fiber filaments run. The tubular channel has openings on both sides and is arranged in a semi-closed manner with equal spacing along its long diameter. The nozzles are connected in series inside the tubular channel and are made of metal. The nozzles are welded to the inner diameter of the tubular channel below. The spacing between the nozzles is arranged in an arithmetic sequence of 1:3:5:7. The temperature of the nozzles is 165℃-185℃.

[0032] Actively clamping tension controllable rubber rollers stretch the tubular channel before and after, generating a traction differential. The speed ratio of the actively clamping tension controllable rubber rollers before and after the tubular channel is 0.1-0.5, resulting in multi-compartment flash temperature absorption color controllable tension acetate and triacetate fibers. The multi-compartment flash temperature absorption color controllable tension acetate and triacetate fiber yarn can be either filament or staple fiber yarn. The filament is formed in one step, while the staple fiber yarn can be cut.

[0033] Multi-compartment flash temperature absorption color controllable tension acetate and triacetate fibers are cut and processed according to cotton-type length, medium-length length, and wool-type length and blended with other materials, such as natural cotton, linen, wool, silk, etc., and ring spun. By utilizing the difference between coarse D and fine D, irregular yarns with axial changes due to inertia differences are formed.

[0034] Different shaped yarns are woven to form multi-compartment temperature-sensitive color-controlled tension acetate and triacetate fiber fabric. The multi-compartment temperature-sensitive color-controlled tension acetate and triacetate fiber fabric is a woven fabric. The woven fabric has a double weave structure with satin and other plain or horizontal textures. The satin surface uses multi-compartment temperature-sensitive color-controlled tension acetate and triacetate fiber yarn, while the plain or horizontal textures use yarns with higher shrinkage characteristics than multi-compartment temperature-sensitive color-controlled tension acetate and triacetate fiber yarn, which further highlights the texture style.

[0035] The multi-compartment flash temperature absorption color controllable tension acetate and triacetate fiber fabric is a knitted fabric. The knitted fabric has a weft-knitted plain weave structure. The knitted fabric uses multi-compartment flash temperature absorption color controllable tension acetate and triacetate fiber yarn covered with high-shrinkage PE composite yarn, and uses the principle of differential shrinkage to highlight the texture of acetate.

[0036] The finished product is produced by dyeing multi-chamber flash temperature absorption controllable tension acetate and triacetate fiber fabrics.

[0037] This invention utilizes a multi-chamber flash temperature absorption controllable tension acetate and triacetate fiber yarn and production method to achieve fiber deformation, forming discontinuous color absorption differences and a slub-like style. It forms the fiber fabric characteristics of slub-like texture of acetate and triacetate fibers in a one-step process, improving production efficiency, reducing waste, and forming rich fabric features. It solves the problems of difficult processing, low efficiency, high waste, and high cost of slub-like fabrics made of acetate and triacetate fibers, while increasing the variability and possibilities of acetate and triacetate fiber fabrics.

[0038] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
