Triple combing spunlace nonwovens: How to achieve a perfect balance between tightness and softness?

The production of triple combing spunlace nonwovens begins with the careful preparation of fiber raw materials. Unlike traditional textile processes, the production of nonwovens does not require spinning and weaving processes, but directly forms a fabric with a certain strength and structure by directly combing, laying, and reinforcing the fiber raw materials. And triple combing is a crucial part of this process.

The so-called triple combing refers to the three-time fine combing of the fiber raw materials through three sets of combing equipment with different functions after the initial opening. This process not only removes impurities and short fibers in the fiber, but also makes the long fibers fully parallel and oriented. More importantly, triple combing ensures the uniform distribution of fibers in subsequent processes, laying a solid foundation for the tight winding of the fiber web and the uniformity of the fabric.

If triple combing is the cornerstone of nonwoven production, then the spunlace process is the key to achieving a balance between tightness and softness. Spunlace, as the name suggests, is a process method that uses high-pressure water flow to impact and reinforce the fiber web. In this process, high-pressure water flows through a precisely designed nozzle and sprays onto the fiber web at a very high speed. The impact force of the water flow causes intense friction and entanglement between the fibers, thereby achieving close bonding of the fibers.

The uniqueness of the spunlace process does not lie in its simple physical effect, but in its ability to maintain the original softness and comfort of the fibers while achieving close bonding of the fibers. This is because during the entire spunlace process, the role of the water flow is mainly to interweave and lock the fibers at the microscopic level, rather than to achieve reinforcement through physical compaction or chemical adhesives. Therefore, even if the fiber web is reinforced with high-intensity spunlace, the final fabric can still maintain a soft and comfortable feel.

This feature is achieved thanks to the minimization of fiber damage by the spunlace process. Under the impact of high-pressure water flow, although there is intense friction and entanglement between the fibers, the fibers themselves are not excessively damaged or hardened. On the contrary, the impact and friction of the water flow help to micronize the fiber surface, increase the contact area between the fibers, and thus improve the bonding force between the fibers and the strength of the fabric.

The key to the balance between tightness and softness of triple-combed spunlace nonwovens lies in their unique production process and fiber structure. Through triple combing, the fibers are fully arranged and oriented in parallel to form a uniform and dense fiber web. The spunlace process uses the impact force of high-pressure water flow to tightly interweave and lock the fibers, thereby strengthening the fiber web and improving the strength of the fabric.

However, unlike general reinforcement processes, the spunlace process does not sacrifice the softness and comfort of the fabric. On the contrary, due to the micro-refining of the fiber surface by the impact force and friction of the water flow, and the tight interweaving structure between the fibers, the triple-combed spunlace nonwoven fabric can maintain a soft and comfortable feel while maintaining high strength. This feature makes triple-combed spunlace nonwovens show a wide range of application prospects in many fields.

The balance between tightness and softness of triple-combed spunlace nonwovens provides unlimited possibilities for its application in many fields. In the field of medical and health care, it is widely used as a raw material for medical dressings, surgical gowns, masks and other products. These products not only need to have certain strength and durability, but also need to have good breathability and comfort. Triple carded spunlace nonwovens just meet these requirements. Its tight structure can effectively block the invasion of bacteria and viruses, and its soft touch can reduce irritation and discomfort to the skin.

In the field of personal care, triple carded spunlace nonwovens also show great application potential. It is used as raw materials for products such as wet wipes, cotton pads, and baby diapers. These products need to have soft, absorbent, and breathable properties. The tight structure of triple carded spunlace nonwovens makes it have good water absorption, and its soft touch can provide users with a more comfortable use experience.

Triple carded spunlace nonwovens are also widely used in household goods, automotive interiors, packaging materials and other fields. Its tight structure and soft touch make these products not only have good appearance and texture, but also have certain durability and environmental protection.

With the advancement of science and technology and the expansion of the market, the application field of triple carded spunlace nonwovens will be more extensive. However, in the face of increasingly fierce market competition and environmental pressure, how to achieve green and sustainable production processes while maintaining product performance has become an important challenge facing the triple-combed spunlace nonwoven industry.

On the one hand, it is necessary to continuously innovate production processes and raw materials to improve product performance and added value. For example, by developing new fiber materials and optimizing combing and spunlace process parameters, the strength, air permeability and softness of triple-combed spunlace nonwovens can be further improved. At the same time, it is also possible to explore combining triple-combed spunlace nonwovens with other functional materials to develop new products with special properties and application areas.

On the other hand, it is necessary to focus on the environmental protection and sustainability of the production process. By adopting environmentally friendly raw materials, optimizing production processes, reducing energy consumption and waste emissions, the environmental burden in the production process can be reduced. At the same time, it is also possible to explore the recycling and reuse of waste triple-combed spunlace nonwovens to achieve resource recycling and sustainable development of the industry.
