Textile raw materials are a relative concept.
For cotton mills, textile raw materials refer to everything used
spinning
Natural or
Chemical fibre
.
During the Spring and Autumn Period and the Warring States Period and the early Western Han Dynasty, textile technology had reached a very high level, and the main raw materials were hemp and silk. Silk cultivation is one of the world's recognized great inventions, as early as 2000 years ago was transmitted to Southeast Asia, 1800 years ago to Korea and Japan, 1600 years ago to Central Asia, 1400 years ago to Greece, 900 years ago to Italy, the Italians are inspired by the silk cultivation after the invention of chemical fiber production technology! From the Han Dynasty to the Tang Dynasty, a large number of exquisite silk fabrics were exported by land and by road, opening up the famous "Silk Road" in history, and China was thus praised as "the country of Silk" by Eurasian countries.
In the Song and Yuan Dynasties, with the extensive cultivation of cotton in the Central Plains and the Yangtze River Valley, the handmade cotton textile industry developed rapidly, and cotton gradually became the main textile raw material.
Because cotton is suitable for concentrated cultivation, high unit yield, good performance, coupled with the development of cotton textile processing technology, especially since the middle of the 18th century, the steam engine as the power, the cotton textile industry as the leading industry, the combination of the two took the lead in the United Kingdom to promote the world's first industrial revolution, from cotton production on the world's dominant position in textile fibers, Until the 1950s, cotton and cotton textile industry has been in the center of the world textile industry. Although silk and wool have a long history, due to various restrictions on breeding conditions and regional environment, the output has been in a weak position and can only be used as a precious textile raw material. Therefore, from the world's first industrial revolution to the middle of the 20th century, the cotton-based textile industry has dominated the world textile industry for 200 years.
World War II
After the end, to
Viscose fibre
Cellulose fiber as the main body and synthetic fiber with "nylon, polyester, acrylic fiber" as the three pillars began to enter the industrial mass production. The birth and development of chemical fiber is a great revolution in the history of the world textile industry, which is changing the whole face of the textile industry. In a short period of more than 30 years, on the one hand, it has quantitatively promoted the unitary attribute of textile industry which has been attached to agriculture for thousands of years to the dual structural system characterized by agriculture and industrial processing; On the other hand, it can rely on people's wisdom and strength to create fibers with unprecedented special functions from the use of performance, making it become the basic raw materials in industry, agriculture, transportation, medicine and health and many high-tech fields, and developing the textile industry from the original simple processing industry into a composite industry of raw material industry + processing industry.
People's quality of life is constantly improving, and they are increasingly pursuing comfortable and environmentally friendly clothing. Natural textile fibers are favored because of the advantages of comfortable wearing, good air permeability, health care, anti-static and antibacterial, while natural textile fibers are biodegradable and renewable, in line with the requirements of clean environmental protection and sustainable development. Fossil resources such as oil are continuously depleted, and it can be predicted that natural textile raw materials will become the leading raw materials of the textile industry. Natural textile fibers will maintain a strong market demand, and the application of clean natural raw material refining technology and the development of new natural fiber raw materials will make greater progress.

Sea island cotton
Produced from several islands of the Caribbean coast, because of the long sunshine time in the region, the sun is full, so its fiber is thin and long, shiny, strong toughness, good softness, water absorption, is the best fabric for summer clothing. But the output is very small, very precious, with island cotton clothing prices are generally around 2000.00, PC and AQ clothing have such products. ③ Various detergents can be used in washing, and can be washed by hand. White clothes can be washed at high temperature with strong alkaline detergent to play a bleaching role; Do not soak for a long time, underwear can not be soaked in hot water, so as to avoid yellow sweat spots, wash in time, deep and light color separate; It should be dry in the sun, avoid exposure to the sun, so as not to fade dark clothes, when drying in the sun, the inside will face out. Do not wring out.
The characteristics are basically similar to cotton, which is more absorbent and cooler to wear. Cons: Easy to wrinkle, rough fabric, no smooth feeling when wearing.
Mainly wool and cashmere, its advantages are warm, light, no wet feeling when wearing, soft and comfortable, rich color, water is not easy to fade. Disadvantages: washing water treatment is difficult, can not be washed by machine, need to be flat dry, easy to deform, strong shrinkage. PC wool clothing is selected from the wool of the best quality ----, that is, "fine sparse wool", not only feel good, fine texture, quality is more guaranteed. In addition to retaining the characteristics of wool: warm, gentle, breathable, but also with "washable", "shrinkable water" and other functional functions, suitable for general household washing methods, can save economy, achieve throttling effect to play the throttling effect. The mercerized wool garment can even be machine washed. When washing, dry cleaning is the best cleaning method. If it is indicated that water can be washed, hot water, alkaline or concentrated acid washing is prohibited. Dissolve in 30 degrees of neutral washing water, then put people to wash, gently scrub, can not be washed with a brush, after washing naturally flat dry, ironing, the temperature should be moderate (about l40 degrees), it is best to pad a cloth on the ironing.

21, what is the count? What are high, medium and low branches?
textile
Cotton yarn
There are thick, there are thin, and this degree of thickness is usually used
count
To represent. The count is also a sign used to compare the thickness of cotton yarn, represented by "S".
High-count yarn
: refers to more than 29 yarns;
Medium yarn: refers to 18-28 yarn;
Fiber type/longitudinal form/cross section form
Tencel fibre
/ Smooth/more regular round or oval, with skin core layer
Modal fibre
/ There are 1~2 grooves in the longitudinal direction/irregular waist circle, more smooth and leather core
Soy protein fibre
/ The surface has irregular grooves and island convex/flat dumbbell shape and round waist
Bamboo fiber
/ The surface is grooved/serrated, with skin core layer
Viscose based chitin fiber
/ The surface has obvious grooves/edge jagged, and the core layer has obvious small gaps
Definition: The fabric is burned on an open flame, and the deformation of the fiber after heat is observed, the flame condition, the difficulty and speed of combustion, the smell and color emitted, the shape of the ashes and leftovers after combustion, the hardness and other methods are identified.
Very simple method:
Cotton, burning in case of fire, fast, yellow flame, slightly gray smoke and burning paper smell, burnt embers soft, dark gray.
Hemp fiber: similar to cotton, but ash is grayish white.
Wool, does not burn, in case of first curl, after burning fiber foam, flame is orange, in the taste of burning protein, burning speed is faster than cotton, ash, is not formed black brown shape, crushed by hand, into loose powder.
silk
: Burning shape with
Wool fibre
Similar, first rolled into a ball, burn faster than wool, protein flavor, but less odor than wool. When burned, it turns into a brown ball.
Viscose fibre
: Similar to cotton, burns faster than cotton, yellow flame, burning paper odor, ash or light gray.
Tapefibre: Drops molten material when burning, and the flame is blue. There is black smoke on the top, slightly aromatic smell, and the ash is hard, and the finger is crushed.
Nylon: not easy to burn, see fire first curl, melt for transparent glue, while hot can pull out the silk, celery taste. Ashes do not break easily.
