In addition to being hit daily by electrostatic piapia, it can be said that the velvet coats are the king's equipment for the southern autumn and winter season, looking warm and touching warm and dressed. But when you look at the material, eh? Polyester fibres, isn't this a scrubber, or is it true what the old man said? Not natural materials or cotton products, but fibres。
Fibres, or chemical fibres, including regenerative fibres and synthetic fibres, used to be endlessly desired by older chinese people, but now demonized. Infinite thirst is due to the fact that well-made shirts and shrubs are too cold, and are much more of a quality and permeable than pure cotton; demonization, like food safety problems now, is the mouth of a fiber that is not natural and does not have pure cotton。
But i personally prefer fibre-optic material to pure cotton, and my own clothing choices favour cheaper but more comfortable fibre-optics, such as scrubbing and ammonia. Today's pleasure coincides with the common fibre-optic species used in garments and their products, many of which are already used on a daily basis, but you see it as a fibre-optic product for cotton-specific manufactures。
1. Chemical fibre base classification and manufacturing principles
Chemical fibres are chemically and mechanically manufactured fibres, which are divided into two broad categories according to source of raw materials and method of manufacture:
Regenerated fibres (regenerate fibers): based on natural high molecular compounds (e. G. Cellulose, protein) which are dissolved or chemically modified and then made through silk. Synthetic fibres (synthetic fibers): based on oil, coal, natural gas, etc., chemically synthesized high-molecular compounds, which are made of silk. 1. 1 core manufacturing process: threading principle
Both regenerative and synthetic fibres ultimately require liquid high-molecule polymers to be converted into solid fibres through a silking process. There are three main methods of silking:
Advantages of applying fibre core principles to silking methods
Melting silk
Cleaning up, making up, making up
The polymer is heated and melted into a melt, squeezed out through a blowtorch and cooled into the air and condensed into silk。
Short, fast, low-cost, environmentally friendly processes。
Dry silk
Pyramid, ethylene fibre
Melting polymers into volatile solvents forms silk fluids, which then flow into thermal air and the solvent evaporates into silk。
For polymers with poor heat stability。
Wet silk
Glucose fibres, mussels, ammonia
The polymer is dissolved in the solvent, squeezed out into the condensed bath (chemical solution) and filamented through chemical reactions。
For non-melt, insoluble polymers。
2. Synthetic fibers
Synthetic fibres are the main force of fibres used in clothing and are dominated by their superior strength, durability and functionality。

2. 1. 3 varieties and modification techniques
The extensive application of scrubbers has benefited from their diverse adaptation technologies:
Mid-air scrubber: fibre cross-section with medium-empty structure。
High condensation: high contraction rate after heat treatment。
Wet-swept-swept (an alien cross-section): fibrous cross-sections are multi-leaf (e. G., three, five leaves)。

5. Summary: unlimited possibilities of fibres
Chemical fibre has completely changed the textile industry with its plasticity, functionality and cost-effectiveness. From daily wrinkle-resistant shirts to extreme bulletproof vests and wet-proof assault suits, fibres are used everywhere. By controlling molecular structures and cross-section shapes, fibres can imitate or exceed the performance of natural fibres and achieve special functions that cannot be performed by natural fibres。
The key to the design and construction of modern costumes is mixing and functional superimpose:
Chemical fibres continue to develop, focusing on bio-based, degradable (e. G. Pla) and intelligent functions (e. G. Ppm, conductive fibres) to meet growing environmental needs and high performance requirements。
