The raw materials of paper are mainly plant fibers at the present stage. Raw materials for cloth range from natural to chemically synthesized.
Although they are literally fibers, there are differences.
The plant fiber used to make paper is the cell wall of the plant. Microfibrils composed of cellulose, reconstituted fibers. It can be rice straw, bamboo, reed, and various kinds of wood. Due to the different processing methods, there will be a small amount of hemicellulose and lignin in it. They are all natural materials, limited by the shape of the organism itself, and the fiber length and width are all within a certain range. When used to make paper, the cost is lower, and compared with the application scene of cloth, the strength is low. Paper is made of short fibers interwoven with each other, and the hydrogen bonds between the fiber interweaving points bring strength to the fibers. Since paper is a network structure formed by fibers, it absorbs water and swells to destroy the hydrogen bonds between fibers and lose its strength. In order to increase the strength of fiber interweaving points, it is necessary to require fibers to have a certain width, which can be divided into filaments and brooms during processing, that is, to roughen a "bare stick" fiber into a "broom shape" with burrs. This increases the bonding points between the fibers. increase the strength of the network structure.
Textile fibers are defined as natural or synthetic filamentous substances. It is mainly defined in terms of form, emphasizing thinness and silk, that is, it must be long and thin.
Cloth is a textile, and the strength of the textile comes from the strength of the fiber itself and the friction between the fiber structures. It is the strength of physical construction. Cotton, wool, silk, plant and animal natural fibers, and various chemically synthesized nylon, polyester, acrylic, and spandex filaments. Threads are composed of filaments, which are woven into cloth.
To weave cloth with papermaking raw materials, if it is possible, then it is cotton and linen. Ancient Chinese papermaking raw materials, broken fishing nets, and old cotton and linen clothes are processed into papermaking raw materials through pulping technology, and ancient Chinese paper is produced.
Most modern papermaking uses bamboo and wood. To make cloth from these raw materials requires chemical modification of the fibers. After the natural plant fiber is hydrolyzed, the spinneret is re-synthesized. Generate silk that meets the textile requirements and then use it in textiles. Bamboo charcoal and bamboo fiber clothes, which are often heard in life, all use this method. But the non-woven fabrics that are often heard: non-woven fabrics are made of paper-making fibers and non-woven fabrics. But can not satisfy the use of high-end clothing.
If chemical fibers are used to make paper, the hydrogen bonds that form a network structure cannot be formed, and paper can be made. But it's just a structure of interwoven and stacked fibers, without the strength of paper. In short, the fibers are distributed according to the process of paper, but the individual fibers are still a loose group. The application scenarios of paper cannot be satisfied.
