Description

Technical Field

[0001] This invention belongs to the field of spinning technology and relates to the improvement of multi-component blended spinning production technology, specifically a method for producing ultra-multi-component blended spinning. Background Technology

[0002] The combing and carding line is a pre-spinning equipment consisting of a cotton picker, axial flow cotton opener, multi-bin cotton blender, cotton cleaner, cotton conveying pipeline, and carding machine. It is usually also equipped with auxiliary equipment such as fans, spark detectors, and dust collectors. This line handles the entire production process from raw cotton to sliver. Traditional manual blending methods typically involve pre-mixing before placing the cotton into the combing and carding line for processing, thus achieving thorough mixing of various components.

[0003] As the market demands for diverse and differentiated fabrics, textile companies are increasingly requiring the blending of multiple raw materials. Traditional manual blending methods are no longer sufficient to meet these demands in terms of both blending precision and production efficiency. Although automated weighing and blending equipment in the carding and combing industry has seen some application in recent years, its limitations, such as variations in the number and proportion of components, prevent its direct application to the continuous and automated production of blends with multiple components (≥6 types). Traditional manual blending methods are still necessary in this context. Figure 2 As shown, manual cotton blending typically involves pre-blending, followed by placing the pre-blended cotton bales onto a normal carding and combing production line. The pre-blending process involves manually weighing the raw materials to be blended according to a specific ratio, laying them in layers in a pre-blending cotton grabber 10, and then mixing them in a multi-bin blender 2 before feeding them into a baler 3 for baling. The pre-blended cotton bales are then arranged in a specific pattern and fed into the cotton grabber 1 area of ​​the carding and combing production line. After passing through a heavy-duty separator 4, an axial-flow opener 5, a multi-bin blender 2, and a carding machine 6, they enter the carding machine 7. The heavy-duty separator 4 and the axial-flow opener 5 can be selected according to requirements.

[0004] However, this manual cotton blending production method has many drawbacks: 1. Low blending precision and poor mixing uniformity; 2. Cannot be produced continuously, resulting in low output; 3. High management requirements and high production risks; 4. Requires a large amount of manual labor for cotton blending, resulting in high labor intensity and high production costs; 5. Long production process, resulting in significant fiber damage and affecting yarn performance, etc.

[0005] How to design a blended spinning production method that integrates cleaning and carding of multiple components, mainly to solve the problems of continuous and automated production and long production processes in blended spinning of multiple components, is a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0006] To address the aforementioned problems in the prior art, this invention provides a method for producing multi-component blended yarns. This method solves the problems of poor mixing uniformity and low production efficiency in traditional manual cotton blending. It eliminates the need for manual pre-mixing or participation in cotton blending, enabling continuous and automated production of multi-component blended yarns. Furthermore, it features shorter production steps, higher production efficiency, stronger controllability of production risks, lower production costs, less risk of fiber damage, and superior yarn performance.

[0011] Step 3: The raw materials from Step 1 and Step 2 are weighed and mixed in proportion inside the single-fiber weighing and mixing cotton blending equipment;

[0012] Step 4: The fibers mixed by the single-fiber weighing and mixing cotton blending equipment are further mixed evenly through a multi-bin cotton blender, cotton cleaner and carder; the single-fiber weighing and mixing cotton blending equipment is then connected to the blending production line.

[0013] Improvements to the above technical solution: The raw materials are at least 6 kinds, and the single-fiber weighing and mixing cotton blending equipment is at least a 4-component weighing and mixing cotton blender; In step 1, at least 2 kinds of raw materials are first placed into the packing area of ​​three premixing cotton grabbers and grabbed separately, then weighed and mixed by the multi-fiber weighing and mixing cotton blending equipment, and then fed together with the raw materials in the mixing cotton grabber into the single-fiber weighing and mixing cotton blending equipment for weighing and mixing. The premixing cotton grabber is a disc cotton grabber or a reciprocating cotton grabber.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings.

[0025] See Figure 1 This invention discloses an embodiment of a multi-component blended yarn production method, which employs a combing and cleaning system to produce blended yarn. The combing and cleaning system includes a multi-fiber weighing and mixing blending device 8, a single-fiber weighing and mixing blending device 9, a pre-mixing cotton grabber 10, a mixing cotton grabber 1, a multi-bin blending machine 2, a cotton cleaner 6, and a carding machine 7. The production method includes the following steps:

[0026] Step 1: Discharge at least two raw materials in smaller proportions into the premixing area of ​​the cotton grabber 10 corresponding to the multi-fiber weighing and mixing cotton blending equipment 8, and mix the raw materials in proportion;

[0027] Step 2: Discharge at least four types of raw materials into the cotton grabbing area of ​​the cotton grabbing machine 1 corresponding to the single fiber weighing and mixing cotton blending equipment 9;

[0028] Step 3: The raw materials from Step 1 and Step 2 are weighed and mixed in proportion inside the single-fiber weighing and mixing cotton blending equipment 9;

[0029] Step 4: The mixed fibers from the single-fiber weighing and mixing cotton blending equipment 9 are further mixed evenly through the multi-bin cotton blender 2, cotton cleaner 6, and carding machine 7; the single-fiber weighing and mixing cotton blending equipment 9 is then connected to the blending production line.

[0030] Furthermore, there are at least 6 kinds of raw materials, and the above-mentioned single fiber weighing and mixing type cotton blending equipment 9 is at least a 4-component weighing and mixing machine; in step 1, at least 2 kinds of raw materials are first placed into the packing area of ​​three premixing cotton grabbers 10 and grabbed separately, then weighed and mixed by the multi-fiber weighing and mixing type cotton blending equipment 8, and then fed together with the raw materials in the mixing cotton grabber 1 into the single fiber weighing and mixing type cotton blending equipment 9 for weighing and mixing. The above-mentioned premixing cotton grabber 10 is a disc cotton grabber or a reciprocating cotton grabber.

[0031] Furthermore, the aforementioned single-fiber weighing and mixing cotton blending equipment 9 is connected to two blending lines to achieve the function of simultaneously blending two varieties.

[0032] Furthermore, a cotton conveying fan and a metal spark detector are installed in the cotton conveying pipeline of the premixing cotton grabber 10 connected to the multi-fiber weighing and mixing cotton blending equipment 8; a cotton conveying fan and a metal spark detector are installed in the cotton conveying pipeline of the mixing cotton grabber 1 connected to the single-fiber weighing and mixing cotton blending equipment 9.

[0033] In specific implementation, a weight separator 4 and an axial flow cotton opener 5 can be sequentially connected in the cotton conveying pipeline of the pre-mixing cotton grabber 10 connected to the multi-fiber weighing and mixing cotton blending equipment 8. A weight separator 4 and an axial flow cotton opener 5 can also be sequentially connected in the cotton conveying pipeline of the mixing cotton grabber 1 connected to the single-fiber weighing and mixing cotton blending equipment 9. The blending line after the single-fiber weighing and mixing cotton blending equipment 9 includes a multi-bin cotton blender 2, a cotton cleaner 6, and a carding machine 7 connected in sequence.

[0034] In addition, a cotton conveying fan and a spark detector can be installed in the cotton conveying pipe connecting the cotton cleaner 6 and the carding machine 7.

[0035] Furthermore, the aforementioned cotton grabber 1 for mixing adopts a reciprocating cotton grabber or a disc cotton grabber.

[0036] In a specific implementation of this invention, the single-fiber weighing and mixing cotton blending device 9 can be expanded to a maximum of 6 weighing unit groups, i.e., as shown below. Figure 1 A, B, C, D, E, and F are shown. Because each weighing unit group is supplied with fibers of a single component by the blending cotton grabber 1, the blended yarn containing single-fiber weighing and blending type blending equipment 9 can blend a maximum of 6 components, and is affected by the proportion difference, production line output, etc.

[0037] By using a multi-fiber weighing and mixing type cotton blending equipment 8, the number of components in blended yarns and blended varieties can be greatly increased, such as... Figure 1 The dotted line section replaces the single blending cotton grabber 1. Since the multi-fiber weighing and blending cotton blending equipment 8 supports blending of up to 3 different component varieties, the weighing unit group A of the single-fiber weighing and blending cotton blending equipment 9 is expanded from blending 1 component to blending 3 different components. This allows for the production of 3 fibers with smaller proportions in this weighing unit. Similarly, the blending cotton grabber 1 before weighing units B to F can be replaced in the same way. This blending line can support blending of 18 different components.

[0038] If Figure 1 If two units of the multi-fiber weighing and mixing cotton blending equipment 8 within the dotted box are connected in parallel, the blending line can support blending of up to 36 components.

[0039] By controlling each weighing unit of the single-fiber weighing and mixing cotton blending equipment 9, the simultaneous production of two downstream blending lines can be achieved, that is, the two blending lines can blend different varieties.

[0040] Of course, the above description is not intended to limit the present invention, and the present invention is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present invention should also fall within the protection scope of the present invention.
