Lyocell fiber and pulp flushable fabric: Green innovation of wet-laid web technology

In today's world where textile technology is changing with each passing day, lyocell fiber and pulp flushable fabric have become the shining stars in the textile industry with their unique environmental characteristics and excellent performance. These two materials not only represent the latest progress in textile technology, but also reflect the in-depth practice of the concept of sustainable development. Among them, wet-laid web technology, as a key link in their production process, shows the harmonious coexistence of technology and nature.

On the production line of lyocell fiber, a green transformation from nature to technology is quietly taking place. First, the selected wood or bamboo cellulose raw materials are converted into high-concentration cellulose spinning solution through a series of complex chemical and physical treatments. This process not only retains the natural advantages of cellulose, but also removes impurities through dissolution treatment, thereby improving the purity of the fiber.

The high-concentration cellulose spinning solution after dissolution treatment is fed into precision spinning equipment. These equipment use advanced spinning technology to accurately control the flow and speed of the spinning solution, ensuring that the spinning solution is evenly and stably sprayed onto the wet mesh belt. The wet mesh belt provides an ideal environment for the coagulation of the spinning solution, so that the fine cellulose filaments coagulate rapidly at the moment of contact with the mesh belt, forming a continuous and uniform fiber mesh layer.

As the mesh belt continues to move, this layer of fiber mesh is sent to the subsequent stretching, washing, drying and finishing processes. In these processes, the fiber mesh undergoes a series of physical and chemical changes and gradually solidifies into a lyocell fiber fabric with excellent performance. The stretching process enhances the strength and toughness of the fiber, the washing process removes the residual solvent and impurities, the drying process enables the fabric to reach the ideal moisture content, and the finishing process further improves the appearance and feel of the fabric.

Lyocell fiber fabrics, which have undergone strict quality control and testing, have won wide recognition in the market for their unique environmental protection, comfort and functionality. It not only has excellent moisture absorption, breathability and softness, but also has good wrinkle resistance and easy care, making it an ideal choice for high-end clothing, home textile products and other fields.

Similar to lyocell fiber, pulp washable fabrics also use wet-laid web technology as the core link of its production. However, there are certain differences between the two in terms of raw material selection and subsequent processing. Pulp flushable fabrics use natural pulp fibers as raw materials, and the fibers are evenly distributed on the mesh belt through wet-laid web technology to form a continuous fiber mesh layer.

The production process of pulp flushable fabrics also involves processes such as stretching and consolidation, but more attention is paid to the environmental protection and degradability of the fabrics. To achieve this goal, pulp flushable fabrics usually use environmentally friendly consolidation methods such as spunlace or hot pressing to avoid the use of harmful chemicals. At the same time, water consumption and energy consumption are strictly controlled during the production process to reduce the impact on the environment.

Pulp flushable fabrics have great application potential in the fields of medical care, health, catering, etc. with their environmentally friendly and degradable characteristics and disposable and convenient use. It can not only meet people's needs for convenient life, but also reduce environmental pollution and resource waste generated in the processing of traditional textiles.

As green new stars in the textile industry, Lyocell fibers and pulp flushable fabrics have achieved a green transformation from natural raw materials to high-performance fabrics through the exquisite application of wet-laid web technology. They not only demonstrate the latest achievements in textile technology, but also provide us with a more environmentally friendly, comfortable and convenient lifestyle choice. With the continuous improvement of environmental awareness and the continuous advancement of technology, we have reason to believe that these two materials will occupy a more important position in the future market and contribute more to the sustainable development of the textile industry.
