Washing hair: raw hair → graded → scouring → opening → soaking → drying → removing loess. 2. (2) Put the warp thread on the scorpion-like tool (the Tibetan language is called "the sac day") and fix it; (3) The warp thread is worn back and forth in the shape of the rafter. Tools (called "Renzhi" in Tibetan). According to the width of the crucible and the number of bamboo strips on the "up", the width is generally 28 cm. (4) According to the length of the crepe, the warp thread is wound on the "Renzhi". Finally, fix the "Bag Day" and "Ren Weaving" at both ends of the machine and set up four foot pedals. 3.

(2) Combing with an iron brush, and after combing, the hair is softer, similar to cotton, and made into a roll. (3) 捻 line, use the "side" (ie: a two-headed conical wood) to roll the rolled wool into a weft. When the weft is rotated, the direction of rotation must be clockwise. When making the weft, it can be selected according to the order of 氆氇 to form a thin line or a thick line, and the fine line level is better than the thick line. 4.

(2) When weaving weirs, the hand is operated, and the shuttle is shuttled back and forth through the intersecting warp. Each time the shuttle passes through the warp, it is necessary to use the “up to hit” the weft thread three times, and the bottom of the loom has four pedals. The weavers use the stitches in order. The pedals are pedaled, and the hands and feet are operated together to make the latitude and downward change. By hand, the warp, that is, the "snake" is shuttled back and forth, interlaced with the weft, and the foot is fastened, and the above action is repeated to woven the plaque. 5. Finishing (requirements for semi-finished products): (1) 氆氇 Specifications: 0.28m × 20m, thickness is determined according to 氆氇 grade or order.
