Which type of polypropylene FDY filament is suitable for your product? A scenario comparison table
Polypropylene FDY yarn (fully stretched yarn) is widely used in various industries due to its uniform strength, smooth surface and good dyeability. Different end products have different requirements for FDY yarn. Below, we will help you match them according to common application scenarios.
I. Bag Laces and Backpack Accessories
These products require the surface of the yarn to be smooth, durable, with good color fastness, and at the same time, they need to have a certain degree of softness for easy weaving.
Recommendation focus: Choose Polypropylene FDY yarn or polypropylene colored yarn. The denier should be moderate (such as 600D - 1200D). The surface of the webbing should be smooth and the feel should be smooth.
Color matching: Using color threads directly eliminates the post-dyeing process, and the stability of color batches becomes even more crucial.
II. Industrial Fabrics and Filter Materials
Industrial fabrics have higher requirements for strength uniformity and aging resistance. Filter materials, on the other hand, need uniform yarn thickness and less lint.
Recommendation focus: Polypropylene stretch yarn or high-strength FDY yarn, emphasizing the stability of the CV value (coefficient of strength variation).
Process matching: The requirements for yarn twist and surface smoothness vary for plain or twill fabrics. It is recommended to communicate the weaving process in advance.
III. Fabrics for Inner Linings and Home Textile Accessories
In these fields, more emphasis is placed on soft texture, light weight, good color uniformity, and a high demand for fine-diameter silk.
Recommendation focus: Fine-diameter polypropylene FDY yarn (such as 75D-300D), aiming for softness and smoothness of the fabric surface.
Color selection: For the light color series, the consistency of color among batches of the same yarn is quite demanding. It is recommended to take samples for comparison.
IV. Rope Nets and Binding Materials
Ropes, binding straps, etc. require yarn to withstand certain pulling forces while also ensuring good wear resistance.
Recommendation focus: Polypropylene strong filament or medium-thick FDY filament. They have moderate strength and offer better cost-effectiveness. There is no need to pursue the highest strength; meeting the required tensile strength is sufficient.
Summary and Selection Suggestions
When purchasing polypropylene FDY yarn and related products, it is recommended to confirm as follows:
Designated purpose: Luggage straps, industrial fabric, clothing lining, or ropes? Different scenarios place different emphases on strength, softness, and surface smoothness.
Additional specification: Based on the required thickness and hand feel of the finished product, determine the yarn count range and whether to use colored yarn.
Finally, a sample trial production was carried out: a small-scale trial run on the machine was conducted to observe the breakage rate and the fabric appearance, and then an order of a larger scale would be placed.
Ningbo Dazhong Industrial Fibers Co., Ltd. specializes in the production of polypropylene FDY yarn, polypropylene POY yarn, polypropylene stretch yarn, polypropylene colored yarn, and polypropylene strong yarn. Please feel free to send samples for testing and discuss application scenarios.
