Textile Terms - Plant Fiber

Plant fibers are thick-walled tissues widely distributed in seed plants. Its cells are slender, with sharp ends, thicker secondary walls, and often a single pit on the wall. There are generally no live protoplasts when mature. Plant fibers mainly play a mechanical support role in the plant body.

China's use of plant fibres, especially ramie and ramie, dates back very early and there were linen imprints on Neolithic earthenware. In the Book of Songs, there is already a record of the 沤纻 苎 (苎 苎 苎 麻 麻 ) 麻): "The land of the East Gate, you can 沤纻" ("Chen Feng"). The relationship between plant fibers and human life is very close. In addition to the textile products necessary for daily life, ropes, packaging, weaving, paper, plastics, and plastics are also required as raw materials.

Plant fibers - plant fibers present in plant stems, such as herbaceous stems of ramie, linseed, flax, and jute, with a particularly developed bundle of bast fibers that can be used to make a variety of textiles. These fibers are not or rarely lignified and are called soft fibers. In some woody stems of some plants, tenacity fibers are also very developed. They are excellent raw materials for making special papers such as mulberry, mulberry, and cinquefoil.

The leaf fibers are mainly present in the veins of monocotyledonous plants, with a high degree of lignification of the cell wall and a hard texture called hard fibers. This type of fiber has large tensile strength and strong resistance to decay. It is mainly used for making ropes or for the use of wool spinning, such as sisal and abaca.

The root fiber is generally less, but some plant root fibers can also be used, such as the horse. In addition, some plant fruits contain fibers, such as coconuts, or grow special-purpose fiber hairs such as gibber. The prominent examples of surface growth of seed coats are cotton fibers. Other seed surfaces such as kapok and willow also have fibers. Some of the industrial plant fiber length and width comparison table.

Plant fiber-type plant fibers can be roughly divided into two major categories: xylem outer fiber and xylem fiber, depending on the location of the plant fiber.

The wood fiber type structure comprises xylem fibers, including bast fibers, cortical fibers, and fibers surrounding the vascular bundles. Such fibers are generally long spindles with sharp ends and some ends become blunt to form bifurcations. The cell wall is thick and relatively small relative to the cell cavity. The cell walls have different degrees of lignification or no lignification, and primary fibers are usually longer than secondary fibers.

Xylem fibers, also known as wood fibers, have mostly lignified secondary walls. The cell shape is usually sharp at both ends, but there are variations in shapes and pits. This kind of fiber is one of the important constituent molecules of wood.

Wood fibers can be further divided into two types: 1 Fibrous tracheid cells, which evolved gradually from tracheids (see xylem), with distinct bordered pits on the cell wall. 2 Tough fibers, as a result of the further evolution of fibrous tracheids, the cell wall is thickened and the pits in the wall are degenerated into single-stranded holes, also known as wood fibers. In the wood of some angiosperms (such as eucalyptus), a series of transition types between fibers and tracheids can be seen, ie, the thickness of the cell wall is gradually increased, the length is shortened, and the bordered pits on the wall are gradually reduced to single. Pit holes and so on.

Fibrous tracheids and fibril fibers may have lateral partitions, which are known as separate fibers. Many plants have this structure, such as the genus Vitis and Hypericum. These separated fibers can retain protoplasts for a long period of time and have the effect of storing starch, oils, and resins.

Plant Fibers - Developmental cotton fibers are the parts of the epidermal cells that grow on cotton ovules. Plant fibers develop from different meristems. The xylem and phloem fibers originate from the original formation or formation. Some fibers may occur from the basic meristem. This type of cell that later develops into fiber stops transversal ** very early and only longitudinally. Some of the fibers in the vascular sheath can occur from the original formation and the other from the basic meristem.

The primary fibers have occurred before the organs have been extended, and they can continue to extend to a considerable length while the surrounding cells are still buzzing. For example, the bast fiber of ramie can continue to elongate for several months. The final increase length is 450,000 times and the longest is 55 cm. This cell elongation, in addition to the growth (co-growth) together with the surrounding cells; there is also growth (invasive growth) of the cell tip that can extend into the surrounding cells. After the fiber of castor has stopped stretching, the secondary wall may have a thick secondary wall at the time of secondary wall deposition. However, there is still living content and a thin cell wall on the top, so the cell's tip can continue to elongate.

Cotton fiber is an elongated part of epidermal cells on cotton ovules. Its development process is as follows: When the cotton ovules are fertilized, the hair cells producing fibers on the ovule epidermis rapidly elongate. After that, the cell wall gradually thickens, that is, the cellulose-containing secondary wall is continuously deposited inside the primary wall. As the seed matures, the original tubular fiber cells become flat and distorted, and the remaining protoplasts in the cell wall also dry out. After the boll has cracked, the fibrocytes die and become silvery white cotton fibers.

Plant Fiber - Differentiating Plant Fiber Books Plant fibers are substances that cannot be digested and include cellulose, hemicellulose, lignin, pectin, gums, and some non-cellulosic sugars.

Dietary fiber is a human edible plant fiber. The basic material constituting the plant fibers is cellulose, which is a polymer in which 7,000 to 10,000 glucose molecules are arranged in a bundle and arranged in parallel and connected via glycoside chains.

Plant fiber is a filamentous or flocculent formed by the combination of cellulose and various nutrients. It supports, connects, wraps, and fills plants. Due to the different nutrients, linkages, and attachment sites associated with cellulose, plant fibers can have a variety of different characteristics, and their morphology and tissue structure change significantly as the plant grows and matures. By the time the plants matured, the plant fibers had been gelatinized, keratinized, and lignified. At this point, plant fibers are insoluble in water and cannot be decomposed by human digestive enzymes and are called crude fibers. For example, the buds in the bud and the loofah in the flowering stage are rich in digestible fiber and are delicious foods favored by people. The fiber of the beech wood is mature and aging, so it is inedible and can only be used for papermaking; Can not eat, loofah is used as a dishwashing tool.

It should be pointed out that whether it is digestible fiber or indigestible crude fiber, its lipid-lowering function is unique, and it is an important and irreplaceable food for human beings. [1]

Plant Fiber - Function Plant Fiber Pots Degradable Plant Fiber Pots Plant fibers are used as the main raw material, and its permeability is very good, which is conducive to the growth of flowers. Fiber pots have a very strong ability to absorb solar infrared rays during the day. This is not possible with other kinds of flower pots. The ability to absorb infrared rays is strong, and the temperature of pots will increase. In cold winters, the use of such pots is more beneficial. Plants grow and can protect plants safely for the winter.

The plant fiber itself has some nutrients needed for flower growth. In the process of plant growth, the contained nutrients can be slowly released into the puddle to supply the plant growth. The fiber pots are made from plant fiber and do not harm the body. And the broken flower pots can be degraded and will not pollute the environment. At present, the types of flower pots on the flower market can be described as everything from wooden flower pots, clay pottery, ceramics and plastic flower pots. Wooden flower pots are light, but no colorful colors; clay flower pots have good air permeability, but they are unsightly and heavy. The ceramic pots are beautiful and gorgeous, but they are fragile, high in price, and the plastic flower pots are light and beautiful in color but breathable. Not good, plants are apt to rot, and plastics cannot be disposed of after disposal. Plant fiber pots are the best choice.
