地毯制造不断采用先进技术和新工艺。一项重要的工艺是地毯产品的核心，即为现代地毯衍生的颜色和图案的美丽进行染色。地毯和纤维在不同的生产阶段通过各种不同的工艺从纤维、纱线或地毯进行染色，具体取决于产品用途、工艺经济性和市场对颜色的需求。地毯染色技术已发展到先进工艺，本文对此进行了讨论。纤维可以在挤出时进行染色，就像溶液染色一样；纱线可以进行绞纱染色或段染；或整块地毯可以按照贝克染色或连续染色的方式进行染色。本文首次对这五种地毯染色工艺进行了直接比较，旨在了解更先进制造的技术变革。使用生命周期方法，创建门到门（工厂内）库存，以评估与每个流程相关的资源和能源消耗。生命周期库存是根据产品制造的工艺流程模型创建的，以提供透明度。使用单色剂（β-铜酞菁）和单面纤维（尼龙 6）进行比较。较旧的批量工艺（例如绞纱）消耗最多的水和能源，而最新的先进原液染色工艺则使用最少的能源和水。
Carpet manufacturing continues to adopt advanced technologies and new processes. One important process is central to the carpet product, dyeing for the color and beauty of patterns derived for modern carpets. Carpets and fibers are dyed by a variety of different processes at different stages of production, from the fiber, the yarn, or the carpet, depending on the product use, economy of the process, and market demand for the color. Dyeing technology for carpets has evolved to advanced processes and is discussed in this paper. Fiber can be dyed as it is extruded, as in the case of solution dyeing; yarn can be dyed as in skein, or space dyeing; or whole carpet pieces can be dyed as in beck or continuous dyeing. This paper is the first direct comparison of these five carpet dyeing processes with the goal to understand the technology changes to more advanced manufacturing. Using a life cycle approach, gate‐to‐gate (within the factory) inventories are created to assess resource and energy consumption associated with each of the processes. The life cycle inventories are created based on process flow models of product manufacturing to provide transparency. A single color agent (beta‐copper phthalocyanine) and a single face fiber (nylon 6) are used for the comparison. The older batch processes, such as beck and skein, consume the most water and energy, while the most recent advanced process of solution dyeing uses the least amount of energy and water.
