The physical properties of polyester low melting point staple fibers mainly include the following aspects:
I. Length and Length Distribution
- Length: The average length of polyester low melting point staple fibers is usually between 2.5 and 6 millimeters, but the length distribution range may be wider, generally between 2.0 and 25 millimeters. The shape of the length distribution can be adjusted according to specific processing requirements and the performance requirements of the final product.
- Length Distribution: The uniformity of length distribution has an important impact on the processing performance of the fibers and the quality of the final product. A uniform length distribution helps ensure the consistency and stability of the fibers during the processing.
II. Breaking Strength
- Breaking Strength: Breaking strength is a key indicator for measuring the tensile properties of polyester low melting point staple fibers. A higher breaking strength means that the fibers are less likely to break when subjected to external forces, thus ensuring the durability and stability of the product.
III. Elastic Modulus
- Elastic Modulus: The elastic modulus reflects the stiffness of polyester low melting point staple fibers within the elastic deformation range. A higher elastic modulus means that the fibers can recover to their original shape more quickly after being subjected to external forces, thus ensuring the wrinkle resistance and dimensional stability of the product.
IV. Density
- Density: The density of polyester low melting point staple fibers is usually between 1.38 and 1.40 g/cm³. The density is related to the strength and hardness of the fibers and also affects the dyeing performance of the fibers. Fibers with a lower density are easier to dye than those with a higher density.
V. Melting Point and Thermoplasticity
- Melting Point: The melting point of low melting point polyester staple fibers is usually low, which enables them to melt more easily and achieve bonding when heated. The specific melting point temperature depends on the preparation process and composition of the fibers.
- Thermoplasticity: Polyester low melting point staple fibers have good thermoplasticity and can be reshaped after being heated. This characteristic gives them greater flexibility and adaptability during the processing.
VI. Abrasion Resistance
- Abrasion Resistance: The abrasion resistance of polyester low melting point staple fibers is good, second only to nylon fibers with the best abrasion resistance. This characteristic ensures the durability and stability of the product during long-term use.
VII. Hygroscopicity and Moisture Regain
- Hygroscopicity: Polyester fibers have poor hygroscopicity, which means that their performance may be affected in a humid environment. However, in some specific applications, such as anti-static, filtration, and medical fields, low hygroscopicity may be advantageous.
- Moisture Regain: Moisture regain refers to the water content absorbed by the fibers under standard conditions. The moisture regain of polyester low melting point staple fibers is low, which affects the physical properties of the fibers, such as breaking strength, modulus, and other properties.
