Which kind of polypropylene colored filament is your product suitable for? Select based on the corresponding scenarios. 

polypropylene colored filament (dyed polypropylene filament in liquid form) has its color directly integrated into the fiber, featuring high color fastness, excellent water resistance, and environmental friendliness. It is widely used in luggage straps, outdoor products, clothing and footwear fabrics, industrial fabrics, etc. Different end products have varying requirements for the color saturation, light resistance, and strength of the filament. Below, we will help you match them according to common application scenarios. 

Scene One: Bag Accessories and Ribbon Strips 

These products are required to have bright colors, smooth surfaces, good wear resistance, and also need a certain strength to bear weight. 

Recommendation focus: Select polypropylene FDY colored yarn or polypropylene strong-color yarn with medium denier (such as 300D - 1200D). The color should be uniform and rich, with controllable color difference between batches. When used for high-end luggage, fine denier colored yarn (such as 300D - 600D) can be selected to achieve a more delicate feel. 

Key indicators: Pay attention to the color fastness to friction and color fastness to light of the colored yarn. Avoid color fading during use due to friction or exposure to sunlight. 

Scene 2: Outdoor Supplies (Tents, Sunshades, Outdoor Furniture) 

For outdoor applications, the color fibers need to have high resistance to light and aging, and the color must remain stable under long-term exposure to sunlight. 

Recommendation focus: Use polypropylene anti-aging color yarn that has added UV stabilizers, or choose a pigment system with a higher light fastness level. Dark colors (such as black and navy blue) are more resistant to sun exposure than light colors. The choice can be made according to design requirements. 

Key indicator: During the procurement process, suppliers can be requested to provide data on lightfastness tests (such as xenon lamp aging tests) to assess the degree of color change over the expected usage period. 

Scene Three: Shoe and Clothing Fabrics and Accessories 

In the footwear and apparel industry, there are strict requirements for the softness of the color yarn, the naturalness of the color, and the safety of skin contact. 

Recommendation focus: Select fine-denier polypropylene colored yarn (such as 68D-300D). The fibers are relatively fine, resulting in a soft and breathable fabric. When used for underwear or close-fitting clothing, it is necessary to ensure that the pigments and additives used in the yarn comply with skin contact safety standards. 

Key indicators: Pay attention to the uniformity of color dyeing of the colored silk (no color spots, no color streaks) and the wash-fastness of color, ensuring that the color remains stable after multiple washes. 

Scene Four: Industrial Fabrics and Cables 

In industrial applications, the focus is more on the strength and chemical corrosion resistance of the colored fibers, while the color itself mainly serves as a means of identification. 

Recommendation focus: Select high-strength polypropylene colored yarn or polypropylene strong-color yarn. The denier number should be based on the load requirements (such as 500D - 3000D). Polypropylene is resistant to acids and alkalis and is suitable for use in corrosive environments such as chemical plants and electroplating workshops. 

Color selection: Industrial color threads usually use highly recognizable colors (such as fluorescent yellow, orange, and red) for safety warnings. Fluorescent threads or luminous threads can be chosen. 

Summary and Selection Suggestions 

When purchasing polypropylene colored yarn, it is recommended to follow the steps below for confirmation: 

Primary application and environment: bags and luggage, outdoor items, clothing and shoes, or industrial products? Different scenarios place different emphasis on light resistance, softness, strength and safety. 

Also provide color swatches and specifications: The physical color swatches are more accurate than Pantone numbers. Specify the target thread count (68D - 1800D) and the strength grade (medium strength/strong strength). 

Final sample verification: Conduct on-machine weaving or trial use, observe the color uniformity and weaving smoothness; for outdoor use, it is recommended to conduct a short-term exposure to sunlight test. 

Ningbo Dazhong Industrial Fibre Co., Ltd. was founded in 1984. It produces 15,000 tons of products annually, including polypropylene FDY yarn, polypropylene POY yarn, polypropylene stretch yarn, polypropylene colored yarn, and polypropylene strong yarn. The fineness of the products ranges from 68D to 1800D. The color can be customized. Please feel free to send samples for testing.
