Chapter 169 Loom (Please vote and subscribe)
After saying goodbye to Luo Chong, You Fu rode on a horned deer, followed by the ox cart, which was loaded with several pottery pots and some pottery bowls, two large wooden barrels, one full of white salt, and the other for water. All the children of the You tribe were sitting in the cart, and the adults were following around, like an escort agency about to go out to escort.
Well, it seems that there is no difference between mercenaries and ancient escort agencies, both of which take on some armed escort work.
By the morning, the scorching sun was shining on the earth. It was another sunny day. The water in the rice fields was evaporated quickly. The elders and rat witches who had been watching over the rice fields immediately called a few tribesmen to dig canals to release water to the rice fields.
After one and a half months, the rice has reached the tillering and jointing stage. The height of the rice seedlings is growing like crazy. Almost every day, they look new. Now they have grown from the original height of one foot to the height of Luo Chong's thigh. It is estimated that in two or three weeks, they will grow taller than people. After all, the original species of this wild rice is about two meters.
Xiaodie sat under the pavilion again and started a new day of spinning. In the morning, Luo Chong made another leather strip, put the transmission belt on the new spinning machine, and applied lubricating oil.
There were also a few more people in this work booth dedicated to spinning. Two pregnant women brought back from the Fire Tribe were taken in by Xiaodie and learned to spin with her. Three machines started working at the same time. The more than 30 alpacas in the animal pen turned into bald camels one by one, and were replaced by rolls of fine brown wool.
Luo Chong also sat under the pavilion, holding a piece of tender grass in his mouth and a branch in his hand to draw on the ground.
"Luo Chong, why don't you make a loom for me? Now we are spinning together. You have to make a loom quickly, otherwise we will soon finish spinning the wool."
Xiaodie looked at Luo Chong sitting on the ground without working, holding a piece of grass in his mouth, looking very comfortable, and couldn't help but urge Luo Chong.
"I'm just thinking about how to do it, don't urge me, wait until I figure it out, and then start to do it. Don't make trouble." Luo Chong waved his hand without looking back and continued to draw on the ground.
Xiaodie curled her lips, snorted and stopped talking, while Luo Chong was still trying to recall some information and principles of looms he had seen in his previous life.
There are many styles and structures of looms, but generally speaking, they are basically frame-type, which is similar in all countries in the world. It is impossible to verify where the loom started to spread, but the Han people have had looms since a long time ago.
From the early waist loom to the oblique warp frame loom of the Han Dynasty, they were all created by the ancestors of the Han nationality, which is the pride of the Han nationality.
Luo Chong had seen pictures of looms in books before, and knew its principle. He had also seen people operating real objects to work in museums, but those looms all had one thing in common without exception, that is, they were too big.
The first thing to know about research and development is the purpose, to meet market demand. The needs of the Han tribe are sufficient materials, to be able to mass produce, and to strive for every woman in the family to have a loom, or to lower the conditions further, and form a group of several families, with some spinning, some weaving, and some operating combing machines.
Combing machines and spinning machines are very small, and they don’t take up much space in the house, but the size of the loom is unquestionable. In the standard houses of the Han tribe, each room has an area of two meters by three meters except for the large kang, which is obviously unrealistic to place a large loom.
Therefore, the loom that the Han tribe is going to promote must occupy a small area. If the length is not enough, you can install more shafts on the facade and retrieve it from a high place. So there is this high-legged loom designed by Luo Chong.
The principle of the frame loom is very simple. A rectangular main support frame, a shaft for winding warp, and a shaft for winding finished fabrics. The warp is suspended in the air and stretched and tightened through these two shafts, and then two sets of vertical lifting devices are used to layer the warp. This principle is understood by everyone.
Weaving, which can also be called weaving, is actually a woven fabric composed of weft and warp threads alternately interlaced back and forth.
The grouping of warp threads is also very distinctive. If it is a plain weave, it is arranged from left to right in an ABABAB manner, that is, "A" is a group and "B" is a group. If it is divided by numbers, it is from left to right, and each warp thread is numbered, so all odd numbers are one group, and all even numbers are another group.
Two different groups of warp threads are pulled up and down by the lifting rod and neatly divided into two layers. Then a wooden shuttle shaped like a boat is used to install a roll of weft threads in the boat-shaped cabin, and then the shuttle is held to pass through the two layers of warp threads that are stretched up and down.
The weft thread and the warp thread are then tightened with a weft knife, and then the two groups of warp threads are changed up and down again, and the next shuttle is started to
pull the weft thread. The action is repeated in this way, and the cloth is gradually completed. The loom painted by Luo Chong looks strange. Its warp winding shaft is on the top of the frame, and the warp threads are hung vertically, and then pulled to the middle part of the machine through a horizontal shaft to tighten, so that the horizontal height of the warp threads can adapt to the working height when people sit, which is equivalent to turning the warp threads 90 degrees in disguise.
The cloth winding shaft of this loom is placed under the operating table, that is, when people sit in front of the machine to work, the position of the rolled finished cloth is in front of the knees.
In this way, the machine first goes down vertically from the top, then pulls horizontally to the middle, and finally rolls up from the bottom to the front warp laying track, which can effectively reduce the space occupied, and the horizontal length turns two bends to become a longitudinal extension.
The design width of the whole machine is 1.2 meters, 2.2 meters high, and only one meter thick. The maximum weaving width is one meter. If it is wider, it will not work, because the distance between the two hands of a person is limited. With a distance of one meter wide, it is very difficult to shuttle back and forth on both sides. It takes practice to improve speed and accuracy.
However, this machine is really good at saving floor space. The floor space of 1.2 meters long and one meter wide can save a lot of space in the bedroom.
The lifting rods of the two sets of warp threads are controlled by two foot pedals, and both hands and feet must be operated together when working. Therefore, weaving is a tiring and boring job.
Moreover, this first-generation loom has a major disadvantage, which is that it cannot weave very wide cloth. Generally, the width is only one meter at most. If you want to weave more than one meter, you can't use manual shuttle throwing. You can only use semi-automatic shuttle throwing devices, such as the shuttle on the flying shuttle loom. However, that part requires a spring, but the Han tribe does not have the materials that can be used to make springs.
