The difference between polyvinyl alcohol fiber and polyester fiber

There are differences between polyvinyl alcohol(PVA) fiber and polyester fiber in chemical structure, physical properties and application fields.
First, the chemical structure of polyvinyl alcohol fiber and polyester fiber is different
PVA fiber contains a large number of hydroxyl (-OH) functional groups in its molecular structure, so it has good hydrophilicity and solubility. In the molecular structure of polyester fiber, it mainly contains ester group (-COO-) function group, so it has good water resistance and durability.
Second, the physical properties of PVA fiber and polyester fiber are different
The tensile strength and modulus of polyvinyl alcohol fiber are low, but it has better softness and bending property. Polyester fibers have higher strength and modulus, but are relatively hard and easy to break. In terms of heat resistance, polyester fiber shows good performance and can withstand high temperature processing; The polyvinyl alcohol fiber is easy to melt and decompose at high temperatures.
Third, the application fields of polyvinyl alcohol fiber and polyester fiber are different

Due to the different characteristics of polyvinyl alcohol fiber and polyester fiber, they have their own application advantages in different fields. Polyvinyl alcohol fiber is often used in textile, paper processing, plastic film and other fields, and can also be made into waterproof, moisture-proof, anti-static and other functional fibers. The polyester fiber is often used in the production of clothing, fabrics, ropes and other products with high strength and wear resistance, and is also often used in the production of various plastic products.
In short, there are significant differences between polyvinyl alcohol fiber and polyester fiber in their respective chemical structures, physical properties and application fields. Therefore, in actual production and application, product designers and producers need to choose suitable materials according to different needs.

ElephChem Holding Limited, professional market expert in Polyvinyl Alcohol(PVA) and Vinyl Acetate'ethylene Copolymer Emulsion(VAE) with strong recognition and excellent plant facilities of international standards.
PVA Fibers (polyvinyl alcohol) are high-performance reinforcement fibers for concrete and mortar. PVA fibers are well-suited for a wide variety of applications because of their superior crack-fighting properties, high modulus of elasticity, excellent tensile and molecular bond strength, and high resistance to alkali, UV, chemicals, fatigue and abrasion. PVA fibers are unique in their ability to create a molecular bond with mortar and concrete that is 300% greater than other fibers.
These are monofilament fibers that are available in 3 different lengths and filament diameters.
- PVA RECS 7 - 6 mm - 24 microns
- PVA RECS15 - 8 mm - 38 microns
- PVA RECS 100 - 13 mm- 100 microns
Due to the fine nature of these fibers, and the fact that they disperse into monofilament fibers, they are less likely to be visible in finished surfaces. How visible they are in relation to each other is in direct proportion to their various diameters (7 is least visible, 100 is most visible). Equally true, the smaller the fiber, the more fibers there are for any given unit of measure, the more likely they are to choke mixes at higher dosage rates. Therefore, the PVA100 are dosed at higher rates in the more flowable mixes than are the PVA15.
PVA 100's are favored for their ease of workability compared to the 7's and 15's. These are the most visible of the PVA fibers in finished surfaces due to their length. Ideal for use in flowable (SCC) ECC concrete mixes. PVA fibers can be used as a primary or secondary means of reinforcing artisan concrete objects, including concrete countertops, architectural concrete elements, concrete furniture, and many other applications.
