It is mainly manufactured by the shuttle looms. Abstract— In India the textile industry is growing very fast. Conventional shuttle looms are mainly used during the Most of the earlier established textile industries are using weaving process in the industry. All these shuttle looms are conventional shuttle looms for the production of the cloth. But the too old. In these present conventional shuttle looms, it is advancement in the technology made the textile industry more competitive. The effective usage of the new methods of the necessary to pass a shuttle weighing around half a kilogram weaving technology, which is more energy efficient, makes the through the warp shed to insert a length of weft yarn which production more economical. It is found out that the usage of the weighs only few grams. The shuttle has to be accelerated conventional looms badly affects the cloth production. This study rapidly at the starting of picking cycle and also to be focuses on identifying the problems associated with the low decelerated, stopped abruptly at the opposite end. This production by the shuttle loom and suggesting suitable methods process creates heavy noise and shock and consumes by which these problems can be reduced. considerable energy.

In addition to the need for reduction in lead time, there is an increase in levels of quality expectations, resulting in higher cost of manufacture. Hence, in the present scenario, for high fashion garments, there is a need for technology which can minimize lead time and fabric losses, in addition to the production of garments as per the requirement of the customers in a short span of time. A DPOL (Direct Pattern on Loom) method for weaving fabric in the shape of garment panels (pieces) finished at the edges that could considerably reduce fabric loss and lead time is developed by using the electronic jacquard weaving machine. The main aim of the project is to study the feasibility of the production of Direct pattern on Loom especially on jacquard and to check the lead time required with conventional and this modern method.

  • Make Your Own Cardboard Loom
    Make Your Own Cardboard Loom Overview Though hand weaving was not as prevalent in the 1830s as it had been in the late 18th century, there were still people in rural communities who practiced the art of weaving on a loom. Participants in this activity will make their own simple loom from cardboard and try out a weaving project! Background Wool comes from sheep. Sheep were sheared by hand with a pair of shears (they look like big scissors). Sturbridge farmers clipped between 7000 and 9000 pounds of wool in 1835! The wool was then picked and cleaned, carded, spun, and woven into cloth. OSV’s sheep are bred to resemble the types of sheep you might have seen in New England during the time period. Before the Industrial Revolution, all cloth was woven on a loom, operated by a person. At OSV, you can see costumed historians making fabric on a loom at the Fenno House. Supplies ● Piece of cardboard--it doesn’t matter how big your cardboard is. It can be a square or a rectangle, long or wide. ● Scissors ● Ruler ● Pencil ● Yarn for weaving ● String for warping ● Fork (optional) ● Blunt sewing needle OR popsicle stick/small piece of cardboard to act as a shuttle Directions 1. Lay your ruler along the top of the cardboard. Use your pencil to make marks every ¼”. You will also want your notches to be about ¼” deep, so you can draw a full line if it will help you make the cuts all the same length. 2. Repeat step 1 along the bottom of your cardboard.
