...STITCHING MACHINES A sewing machine is a mechanical device equipped with a needle (or needles) threaded at the point-end, which puncture the fabric periodically as it moves under the needle; each stitch is created as the thread loops onto itself (chain stitch) or locks around a second strand of thread (lockstitch), sewing the materials together. Sewing machines are used in both the home and industry, but are designed differently for each setting. Those for the home tend to be more versatile in terms of the number and kinds of stitches they can perform, but they operate more slowly than industrial machines, and have a shorter life span. Industrial machines are heavier, have a much longer life span, are capable of thousands of stitches per inch, and may be designed for very specialized tasks. Sewing machine is invented by Elias Howe in 1846 and successfully manufactured by Howe and Isaac Merritt Singer. Types of sewing machine systems -There are three types of sewing machine systems * Mechanical sewing machines * electronic sewing machines, and * computerized sewing machines Mechanical sewing machines are controlled by a rotary wheel. They have handles and disk to make changes in the tension or the length or width of the stitch. Electronic sewing machine has more features than the mechanical sewing machine. Instead of turning handles or disk, electronic sewing machines use buttons to adjust length or width of the stitch. Electronic sewing machines have motors;...

...• HOMEPAGE RINGS And TRAVELLERS In most cases, the limit to productivity of the ring spinning machine is defined by the traveller in interdependence with the ring, and yarn. It is very important for the technologist to understand this and act on them to optimize the yarn production. • The following factors should be considered o materials of the ring traveller o surface charecteristics o the forms of both elements( ring and traveller) o wear resistance o smoothness of running o running-in conditions o fibre lubrication o TRAVELLER: Traveller imparts twist to the yarn. Traveller and spindle together help to wind the yarn on the bobbin. Length wound up on the bobbin corresponds to the difference in peripheral speeds of the spindle and traveller. The difference in speed should correspond to length delivered at the front rollers. Since traveller does not have a drive on its own but is dragged along behind by the spindle. High contact pressure (upto 35 N/square mm)is generated between the ring and the traveller during winding, mainly due to centrifugal force. This pressure leads to generation of heat. Low mass of the traveller does not permit dissipation of the generated heat in the short time available. As a result the operating speed of the traveller is limited. Heat produced when by the ringtraveller is around 300 degree celcius. This has to be dissipated in milliseconds by traveller...

...GROUP- II CHAPTER II (Review of Related Literature) Hans Christian Orsted while preparing for an evening lecture on 21 April 1820, he made surprise observation. As he was setting up the materials, he noticed a compass needle deflected from magnetic north when the electric current from the battery he was using switched on and off. This deflection convinced him that magnetic fields radiate from all sides of wire carrying an electric current, just as light and heat do, and that it confirmed a direct relationship between electricity and magnetism. He published his findings, proving that an electric current produces a magnetic field as it flows through a wire. The CGS unit of magnetic induction is named in honor of his contributions to the field of electromagnetism. The magnetic field encircles this straight piece of current- carrying wire, the magnetic flux lines having no definite “north” or “south” poles. While the magnetic field surrounding a current- carrying wire is indeed interesting, it is quiet weak for common amounts of current, able to deflect a compass needle and not much more. To create a stronger magnetic field force (and consequently, more field flux) with the same amount of electric current, we can wrap the wire into a coil shape, where the circling magnetic fields around the wire will join to create a larger field with a definitemagnetic (north and south) polarity; the amount of magnetic field force generated by a coiled wire is proportional to the current...

...Florence Kelley was an American social worker who fought to improve working conditions for women and to better child labor laws. In her speech, delivered the night before the National American Woman Suffrage Association Convention, she spoke of the terrible hours working children are subjected to.To convey her message and persuade the audience to bring change she appeals to the logic and emotions of the reader, and closes with a call to action. To begin the speech, she states a fact; “We have,in this country, two million children under the age of sixteen years who are earning their bread.” Right there at the beginning she established ethos and shows she knows her topic. Another fact she uses shows just how overworked the children are; “In Georgia...

...Child labor was and is still an existing practice in the world today. Manuel, a five-year old worked at a seafood cannery in Biloxi, Mississippi, with a shrimp pail in each hand and a mountain of oyster shells behind his back. He is typical for thousands of working children in the years before the civil war, especially the turn of the century. America's army of child laborers had been growing steadily for the past century. The nation's economy was expanding. Factories, minds and mills needed plenty of cheap labor. Around 1911, more than two million American children under the age of 16 years of age were a regular part of the work force. Many of them worked twelve hours or more a day, six days a week, for pathetic wages under unhealthy and hazardous conditions. Thousands of young boys descended into dark and dangerous coal mines every day, or worked aboveground in the dust of coal breakers, picking slate from coal with torn and bleeding fingers. Small girls tended noisy machines in the spinning rooms of cotton mills, where the humid, lint-filled air made breathing difficult. They were actually kept awake by cold water being thrown in their faces. Three-year-olds could be found in the cotton fields, and twelve-year-olds on factor night shifts. Across the country, children who should have been in school or at play had to work for a living. By the early 1900's, many Americans were calling child labor "child slavery" and were demanding an end to it...

...statistics build Kelley’s logical credibility because they give a numerical indication to the amount of working children in America. Kelley goes on to discuss the wide range of ages at which these children are working “from six and seven years,” to “eight, nine and ten years,” “to fourteen, fifteen and sixteen years.” This adds strength to her argument by emphasizing how widespread the pandemic of laboring children was. Kelley is speaking at a Women’s Suffrage convention, and thusly appeals to the more maternal emotions of her audience by primarily focusing her speech on the struggles of working “little girls.” Kelley evokes a mixture of frustration and pity from her audience by painting a picture of young girls “just tall enough to reach the bobbins,” working all night instead of going to school all day. This statement is doubly effective as it builds both her ethical and emotional appeal. The former demonstrates Kelley’s knowledge of who would be in her audience, and the latter her use of imagery to paint a picture of “little white girls ... working” to appeal to the maternal instincts of her audience and produce a desired reaction....

...In my life generally music plays very significant role - makes it colorful. I have always enjoyed listening to sounds which calm me down and maintain positive emotions. Although jazz music has never been my biggest interest, after I started learning about it in class I began to wonder about phenomena of Jazz. Surprisingly I found out it made me bobbin my head and feel warm inside. The performance I attended was at B.B King Blues Club and Grill located on near Times Square. This neighborhood means you will be battling with pretty big crowd but the place was generally pleasant and accommodating. The band played in a style of Ornette Coleman, known as one of the major innovators of the free jazz movement of the 1960’s. The band consisted four saxophones (2 altos, 1 tenor, 1 baritone) two trombones, three trumpets and instruments for setting rhythm. It was beautiful to see it life, all together, performing so professionally. The pieces were easy to listen to which was unexpected to me. The two songs that caught my attention were “Lonely woman” from 1959 and “Dancing in your head” from 1988. In the song “Lonely woman” I noticed many improvisations and solos. The beginning of the song reminded me of Brass Band’s funeral march from New Olean’s style. On the other hand, in the song “Dancing in your head” I noticed that instruments were not playing together, but they were improvising. I believe this style might be called ‘cool jazz’, which we were introduce to on our last class...

...ITC2004T Textile Studies II Assignment 2 Topic: The history of weaving Background Weaving is not only one of the oldest craft in the world but also one of the significant production methods that sill in use in textile industry. After a thousands year of development, it also becomes the history of human being. In the following, brief information and the history of weaving, including time of Upper Paleolithic Age, Neolithic time, the Middle Ages, the industrial revolution and today, will be discussed. Weaving is the interlacing of two lines of thread, which is known as warp and weft, on a loom at right angles to each other. The warp is the set of vertical thread while the weft means the set of horizontal threads. One warp thread is known as an end. One weft thread is known as a pick. Weaving can be done by hands or machines, which is called as looms. Looms were made by wooden frame and is now made by electronic weaving machine. Although there were different electronic weaving machine, hand weaving is still in practice at the moment. Upper Paleolithic age In the Upper Paleolithic age, the first string was developed by the early man. Handfuls of plant fibers were twisted together. It developed to produce a fine string or thread. This finding leads to the first woven textiles, which varieties sizes of threads and strings knotted and laced together to produce useful items, and opens the era of weaving, spinning and sewing. It was first used to produce interlace...
