Abstract:
The problems of the uneven strip shape and low efficiency of tea de-enzyming and carding machines in the working process were addressed by analyzing the trajectory of tea particles and establishing a force model diagram of tea particles in the pot slot. The three-dimensional geometric model of the tea de-enzyming and carding machine was drawn using UG software, and the simulation model of tea particles was established using EDEM software. The work efficiency of the tea de-enzyming and carding machine was improved, and the rate of broken tea was reduced using the EDEM software to simulate the movement of tea particles in the pot slot under different heights of the convex bar, pot slot angle of inclination, and number of slots. The average velocity and interaction force curve of tea particles were obtained. The influence of the number of slots, the inclination angle of the slot, and the height of the convex bar on the effect of tea into strips were verified using a scheme design based on the quadratic regression orthogonal combination rotation test, and experimental research based on three factors and three levels was carried out. Design-Expert 11 software (Stat-Ease, Minneapolis, MN, USA) was used to optimize the response surface and analyze the regression model of the relevant test data. The 6CSL-800 tea de-enzyming (Anji Yuanfeng Tea Machinery Co., Ltd., Huzhou, China) and carding machine (Anji Yuanfeng Tea Machinery Co., Ltd., Huzhou, China) was used as the verification test prototype, six sets of verification tests were carried out, and the test results showed that the maximum value of the strip rate index and the minimum value of the broken tea rate index were obtained. The order of the indicators affecting the bar-type rate and broken tea rate of the de-enzyming and carding machine from high to low is as follows: the height of the convex bar, the inclination angle of the slot body, and the number of slots bodies. When the height of the convex bar was 10 mm, the inclination angle of the slot was 90°, the number of slots was 12, the bar-type rate was 89.45%, and the broken tea rate was 1.63%. The prediction results of the regression model of the bar-type rate and broken tea rate of the tea de-enzyming and carding machine were verified by employing six sets of control tests with the 6CSL-800 tea de-enzyming and carding machine as the validation test prototype. The actual values of the bar-type rate obtained from the six sets of control tests were 88.19%, 90.37%, and 87.33% (1,2,3 group), and the actual values of the broken tea rate were 1.66%, 1.69%, and 1.61% (4,5,6 group), with average values of 88.63% and 1.65%. The control test was basically consistent with the results of parameter optimization. The processed finished tea has good quality, which can provide theoretical reference for the optimization and design of tea de-enzyming and carding machines and similar tea machines in the future.

Abstract:
The quality of the produced yarn mainly depends on the properties of the raw material, its preparation for spinning, the condition of the equipment, and the preservation of the natural quality of cotton fiber during processing. The question of the number of defects in cotton fiber and their total content is a very important issue for cotton spinning. The non-standardized number of defects in the raw material reduces the quality indicators and yarn yield, which requires additional technological processes; therefore, on the part of production, the requirements for reducing the share of cotton fiber defects are constantly increasing. During processing in blowing and cleaning units and on carding machines, the cotton fiber is mechanically damaged. To observation the damaged fibers, we used the Congo-Roth red paint according to the method of Ch. Dore. Despite the carding is considered the last stage in the process of cleaning the fibers from impurities and defects in the spinning system, 30% of impurities and fiber defects still remain on the card sliver. Besides, it should be noted the carding machine is also considered an additional occurrence of defects, in particular (neps), which reduce the quality indicators of the card sliver and the finished product.

Abstract:
Deflections of a thin cylindrical shell that is used in carding machines, either as a swift or a doffer, are analyzed in this paper. The shell may have supple supports at its edges and inner strengthening in the form of rings. The task of calculating the deflections has been solved by dividing the shell into longitudinal beam elements. The optimization procedure for criteria of mass minimum or deflection minimum is used. A numerical example to define selected construction data is presented along with the results.

Abstract:
The article analyses the straightening of fibres in the working areas of roller carding machines. The initial assumptions and parameters are given, which were used to develop a computer model for statistical simulation of the process, taking into account the elastic-viscous properties of fibres and their interaction with neighbouring fibres, based on the methods of statistical dynamics. The dynamics of changes in the straightening of the fibres depending on their initial straightening and the number of passes of the fibres through the working zones are studied. It is established that the partial restoration of the tortuosity of the fibres due to their elasticity does not allow for their complete straightening, regardless of the number of repeated passes of the working areas of the machine.

Abstract:
Fibers are the main raw materials in the textile industry. Now-a-days various types of fibers are available around the world, but all fibers are not textile fibers. Because for being textile fibers, the fibers must have some particular physical and chemical properties. The length of natural fiber plays an important role both in the spinning process and product quality. In this work, it is highlighted about a long staple natural fiber which is called jute fiber. In the 19th century, jute fiber was called the *Golden Fiber* of Bangladesh. After that this fiber lost its name and fame for the cause of our negligence and lack of knowledge. It is very difficult to know about jute because a few people were working on it. Though it’s a long fiber but there are some problems with its fixed length because this fiber consists of a large number of ultimate cells whose length is 1.5 to 4 millimeters, and these cells are attached by lignin which is known as natural cement. A long fiber which is 5 to 10 feet forms after attaching these ultimate cells. During the retting period some of the lignin layers break down and long fiber length of fibers becomes shorter. Another important thing is these fibers have a mesh structure for this reason it’s difficult to identify the actual length of the fibers. That’s why fibers obtained after retting are passed through jute carding machines. The main function of the jute carding machine is to split up and break down the mesh structure. After carding, it’s quite easy to measure the length of splitted jute fibers. There are not any suit-able machines for measuring the length of jute fibers. Previously people use the scale for measuring the jute fibers' length manually, through this it is so difficult to measure the length of the long fibers accurately. Here an instrument has been designed with Arduino UNO, Ultrasonic distance sensor, Image-j software, C-programming and fabricated for measuring the fibers' length easily and accurately as well as this instrument can measure the number of fibers in that particular length. By using this instrument anyone can easily measure the length of the fibers and the number of fibers within a short possible time efficiently.

Abstract:
The properties of fibres make them easily manipulated by aerodynamic forces. The carding machine, used in cotton and wool processing, is an example of equipment that creates aerodynamic forces due to fast rotating cylinders with rough surfaces. These forces are generally seen as an undesirable side effect in fibre processing machinery, exacerbated with modern equipment using faster rotating components. This work attempts to quantify these aerodynamic forces on carding machines used in the wool industry. A combination of boundary layer theory, experiments using hot wire anemometry and flow visualisation, and Computational Fluid Dynamics (CFD) software (Fluent) was used to build up an understanding of aerodynamics in the example of wool carding machines. The theoretical and experimental work progressed along the following topics to determine each effect on carding machine aerodynamics: rough surfaces, centrifugal forces, three-dimensional edge effects, and interactions between rotating cylinders. Examples from each section were modelled using CFD, which was found to accurately simulate theoretical and experimental results in most cases. It could also accurately predict the complex two-dimensional airflow patterns occurring in carding machines. The CFD simulations underestimated the degree of turbulence generated by interactions between rotating cylinders. Three-dimensional effects were overestimated, due in part to attempting to apply the results of an oversimplified model to a full-scale carding machine. In undertaking this work, it was found the universal velocity distribution equations describing flow over flat plates (for both smooth and rough surfaces) could also be used for flow induced by rotating cylinders by compensating for curvature effects.

Abstract:
The new world of New England was one of factories and factory towns, as well as farms and forests. It was a world where farmers, looking to those factory towns for markets, plowed their fields deep and intensively managed their land. It was a world where lumbermen stripped mountainsides of their forest cover to meet the cities’ growing appetite for lumber. It was a world of managed and controlled nature. It was also a world of rapid change, and increasingly after 1800, the force behind that change was the coming of the manufacturing mills. Levi Shepard’s 1788 duck-cloth factory was of a different type than the traditional mills of New England. Although mills that spun or fulled cloth had long been part of rural New England, Levi Shepard had a different market in mind when he encouraged local farmers to bring him their flax. Shepard wanted to take material from the countryside and, with the help of “workers employed,” “manufacture” it into a commodity for sale. Shepard’s decision to focus on manufacturing for distant markets represented a new world. Manufacturing in rural New England began small. And although it made a huge impact on travelers such as Timothy Dwight, it grew out of, while at the same time it transformed, traditional rural society. The processing of goods of the countryside was an integral part of traditional New England life, whether in 1650 or 1800. In 1790, the Hampshire Gazette commented that although “a large quantity of woollen cloth are made in private families and brought to market in our trading towns, a great part of [the woollen cloth] is not calculated for market.” The shift from milling produce for local use to manufacturing occurred initially for most of rural New England with the shift of small traders, merchants, and millers from processing for local farmers to processing for external markets. Edmund Taylor of Williamsburg on the Mill River, for example, at the turn of the century added carding and picking machines to his gristmill. As he did for grain, Taylor processed the material from the countryside, keeping a portion of it as his pay.
