What is polyester fiber
Polyester fiber is a synthetic fiber widely used in textiles, clothing, home furnishing and other fields. In recent years, it has attracted much attention due to its excellent performance and environmental protection characteristics. The following is a detailed introduction to polyester fiber, including its definition, characteristics, applications and market data.
1. Definition of polyester fiber
Polyester fiber (Polyester Fiber) is a synthetic fiber made of polyethylene terephthalate (PET) through melt spinning. Its chemical structure is stable, and it has high strength, wear resistance, wrinkle resistance and other properties. It is currently the largest synthetic fiber in the world.
2. Characteristics of polyester fiber
| Features | Description |
|---|---|
| intensity | Higher than natural fibers, good wear resistance |
| Flexibility | Excellent resilience and not easily deformed |
| chemical resistance | Acid and alkali resistant, not easily corroded |
| Hygroscopicity | Poor hygroscopicity and easy to generate static electricity |
| Environmental protection | Recyclable, partly recycled fiber |
3. Application fields of polyester fiber
Due to its versatility, polyester fiber is widely used in the following areas:
| field | Specific applications |
|---|---|
| clothing | Sportswear, outerwear, underwear, etc. |
| Home | Curtains, sofa covers, bedding |
| Industry | Tire cord, conveyor belt |
| medical | Surgical sutures, protective clothing |
4. Market data of polyester fiber (hot topics in the past 10 days)
According to recent market research and industry reports, demand and production of polyester fibers continue to grow globally. Here is some data:
| indicator | data | Trend |
|---|---|---|
| global production | About 60 million tons/year | Annual growth rate 3%-5% |
| China's share | More than 70% | Ranked first in the world |
| Recycled polyester | Accounting for about 15% | Growth rate reaches 10% |
| price fluctuations | Affected by crude oil prices | Slight increase recently |
5. Environmental protection trends of polyester fiber
With the popularization of the concept of sustainable development, recycled polyester fiber (rPET) has become a hot spot in the industry. Here are its advantages:
| Advantages | Description |
|---|---|
| Resource saving | Made from recycled plastic bottles |
| reduce pollution | Reduce oil consumption and carbon emissions |
| policy support | Many countries have introduced subsidy policies |
6. The future development of polyester fiber
In the future, the polyester fiber industry will develop towards high performance, functionality and greenness. For example:
1.high performance fiber: Develop antibacterial, flame retardant and other special fibers.
2.Smart manufacturing: Improving production efficiency through digital technology.
3.circular economy: Promote the proportion of recycled fiber to more than 30%.
In summary, polyester fiber, as an important industrial material, has broad application prospects, and environmental protection upgrades will become the core development direction in the future.
