Reeds and Density in Carpets: A Comprehensive Guide to Choosing the Right Machine-Made Carpet

Reeds and density are among the most crucial technical specifications of machine-made carpets, significantly influencing their purchase. These two factors play an essential role in the carpet’s appearance, softness, and durability. This article introduces the concept of reeds and density, their importance, and their impact on carpet quality. It also reviews various types of carpets, including 500 reeds, 700 reeds, 1000 reeds, 1200 reeds, 1500 reeds, and 1700 reeds carpets.

What Are Reeds (or transverse density) ?

Reeds refer to the number of knots across one meter of the carpet's width. This number typically represents the level of precision and detail in the carpet’s design. Higher reeds indicate more intricate and fine patterns :

• 500 reeds carpets : An economical and suitable option with simple designs and a high pile, perfect for those prioritizing softness.
• 700 reeds carpets : The most popular type of machine-made carpet, offering a balanced combination of beauty and softness.
• 1000 reeds carpets : Provides more detail compared to 700 reeds but slightly less softness.
• 1200 reeds carpets : Features extremely intricate designs with a handwoven-like appearance.
• 1500 and 1700 reeds carpets : Ideal for those seeking the most beautiful and detailed designs; however, they are less soft due to their lower pile.

What Is Density (or longitudinal density) ?

Density refers to the number of knots in one meter of the carpet’s length. However, this number does not necessarily indicate the exact number of knots. Figures like 2100, 3000, and 4500 labeled as "density" are agreements between machine-made carpet manufacturers and depend on the type of weaving machine used.

Examples of Density and Calculation :

• 500 reeds carpet with 1000 density : This means dividing 1000 by 2, resulting in 500 actual knots per meter in length.
• 700 reeds carpet with 2100 density : This figure is usually divided by 3, resulting in 700 actual knots per meter in length.
• 1000 reeds carpet with 3000 density : Similarly, dividing 3000 by 3 results in 1000 actual knots per meter in length.
• 1500 reeds carpet with 4500 density : This number is also divided by 3, giving 1500 knots per meter in length.
• Carpet with ... reeds and ... density : The actual density depends on the machine type and is divided by 1, 2, or 3.

Note : These divisions depend on the type and technology of the weaving machine used. A precise and universal standard cannot be established for all machine-made carpets. This contractual system allows manufacturers to present technical information in a standardized way to consumers. However, to understand the actual density better, knowing the type of weaving machine is essential.

Higher Reeds and Density Don’t Always Mean Better Quality

Many believe that higher reeds and density equate to better-quality carpets. However, this is a misconception. The quality of a carpet depends on your needs :

• If you value softness and comfort, carpets with lower reeds and density, such as 500, 700, or 1000 reeds, are the best choices.
• Carpets with higher reeds (1200 and above) are less soft due to reduced pile thickness but feature more intricate patterns.

Note : In general, higher reeds and density increase the carpet's weight. To avoid excessive weight, the pile thickness is reduced, resulting in less softness.

Limitations of Reeds and Density in Machine-Made Wool Carpets

In machine-made wool carpets made from 100% pure wool fibers, reeds and density cannot exceed a certain limit. Due to technical constraints in weaving, 100% pure wool carpets are typically produced with reeds equivalent to 35 to 40 rows in handwoven carpets. If reeds and density increase, a blend of wool and synthetic fibers is required.

Conclusion

Reeds and density are essential factors to consider when buying machine-made carpets, but they alone do not determine the carpet's quality. If you prefer softness and durability, 500, 700, or 1000 reeds carpets are better options. On the other hand, for intricate and detailed designs, higher-reeds carpets (1200, 1500, or 1700 reeds and above) are preferable. Pure wool carpets cannot be produced with very high reeds and density due to technical limitations. When selecting a carpet, consider your needs and space requirements to achieve the perfect balance of beauty and practicality.
