The terrain of Luodian is high in the north, followed by the Mengjiang River in the middle, and low in the Hongshui River Valley in the south. For thousands of years, the Buyi people here have lived a simple life of men farming and women weaving. The production of homespun cloth and tie-dyeing techniques by the Buyi people in Luodian are mainly distributed in Bamo and Luoxun in the south of the county, Chengguan and Moyang in the middle, Bangeng, Bianyang, Jiaoyan in the north, Fengting, Naping, Muyin in the west, etc. Since ancient times, the Buyi people have grown cotton, spun, woven, dyed, cut, and sewed their own clothes. Every household has a spinning wheel, a loom, a dye vat, and dyes (indigo). Girls start learning the skills of spinning, weaving, and tie-dyeing from an early age. Smart girls can master this skill proficiently at the age of thirteen or fourteen. The skills of homespun cloth making and tie-dyeing are passed down orally, from mother to daughter, and from master to apprentice, and have been passed down to this day. The Yi people make homespun and tie-dyeing techniques. First, they process the cotton into cat-tail-shaped strips, spin the strips into cotton threads with a spinning wheel, and roll the threads into rolls with a winding frame. Then, a Chinese herbal medicine called Bletilla striata is used to make Bletilla striata paste, add an appropriate amount of water to boil, put the rolled cotton threads in, and boil for a period of time to enhance the toughness of the cotton threads. The cotton yarn after washing and drying is white. To weave cloth with different colors, the cotton yarn must be placed in a dyeing vat and dyed into corresponding colors so that the cotton threads of different colors can be distributed according to the required patterns. After the cotton threads are dyed, the dyed cotton threads of various colors are classified and wound into cone-shaped thread cones for use with a winch. When the threads need to be woven into cloth, the thread cones of various colors are placed on the wiring device, and the wiring device is carried by hand around the pillars and other supports to place the threads according to the weaving format and texture requirements. Then, the distributed cotton threads are threaded one by one into two different thread distributors on the front and back, so that the numerous cotton threads will not appear "a mess" during operation. After the wiring is done and fixed, the thread is connected to the live wheel of the loom through a comb, and then the live wheel is fixed at the tail end of the loom. The thread ends are pulled to another live wheel at the front end of the loom as the warp of the cloth. Finally, small colored threads are put into the shuttle according to the needs, and the thread ends are placed crosswise with the warp as the weft of the cloth. Then the movable pendulum is used to hit it, and the upper and lower rows of warp threads are exchanged by the up and down movement of the foot pedal. Repeatedly, various cloths are woven. The woven cloths include white earth cloth, blue earth cloth, large and small checkered earth cloth, folded earth cloth, reverse yarn earth cloth, etc., which are generally 1.5 feet wide and 4 feet long. It usually takes about 15 days from spinning to weaving cloth. After the cloth is woven, it is made into clothing, bed sheets, waistcoats, etc. Blue cloth, checkered cloth, folded earth cloth, reverse sand cloth, etc. can be directly cut and modified into the required clothing and other bedding. The patterns include mandarin ducks playing in the water, dragons and phoenixes, and rural scenery, which fully express the Buyi people's yearning for beautiful love and a happy life. After the patterns are drawn, they are tied up by hand and put into the dye vat for bleaching and dyeing to the required color depth, then washed and dried, and the cotton thread for tying is removed, and finally inlaid with colorful lace woven with cotton thread. The cloth made by the Buyi people is relatively tough, water-resistant, and resistant to exposure. The quality of cloth woven with small flowers and large flowers is very different. The cloth woven with yarn spun from small flowers is of better quality than the cloth spun from yarn and woven from large flowers, and is bright and bright. Quilts, sheets, clothes, etc. made of cloth for marriage and daughters are all made of cloth woven with small flowers. And large-flowered cloth is used for funerals. Tie-dyeing mainly uses self-grown indigo as a dye, and the dyed cloth is obviously different from modern cloth. In the process of tie-dyeing, the dye used by Luodian Buyi women is mainly indigo. Indigo is a subtropical annual herb. The dyes made from it are fragrant, bright, delicate, and non-fading. They are also sun-proof, warm, and skin-friendly. The indigo has a simple color, beautiful and unique patterns, and is thick and wear-resistant. It is warm in winter and cool in summer, and is breathable and sweat-absorbent. It is a good fabric for Buyi people to make clothes, quilts, and sheets. In the 1970s and 1980s, it was in short supply. Today, tie-dyed sheets sell for 300,400 yuan each, and are also a great gift for guests and friends at weddings. The production and tie-dyeing techniques of indigo have been passed down to this day, and the products are becoming more and more exquisite. The indigo with many colors and the sheets with flowers, trees, birds, and animals embody the wisdom of Buyi people from ancient times to the present. The 1960s and 1970s were the heyday of indigo weaving. However, with the deepening of reform and opening up, due to factors such as production costs and market demand, fewer and fewer women of the younger generation understand textile and tie-dyeing techniques, and a large number of equipment have been destroyed. Only a small number of producers for commercial purposes are still weaving a small amount to sell on the market.
