Description

Technical Field

[0001] The invention relates to the technical field of textiles, and in particular to a wool and functional fabric composite technology. Background Art

[0002] Wool is a natural protein fiber with good curl and elasticity. The curled wool contains a lot of air, so wool fiber can prevent the entry and dissipation of external cold air to a large extent, and has a good thermal insulation effect. Functional fabrics are one of the most used and manufactured materials for outdoor sports. This type of fabric is mainly used in mountaineering wear, ski wear, and assault jackets. It has a rough style and a stiff feel. It has very high requirements for product performance and is suitable for use in expeditions and harsh environments. It plays a protective role for people. The other is outdoor leisure. By mixing with other materials, it has a soft feel and is comfortable to wear, and is suitable for travel and outdoor activities.

[0003] In the field of textiles, as consumers pay more and more attention to the comfort, functionality and environmental protection of clothing, traditional wool fabrics are favored for their excellent warmth retention, breathability and comfort, but they have limitations in wear resistance, wrinkle resistance and waterproofness. At the same time, although functional fabrics perform well in physical properties, they often lack the natural comfort and environmental protection characteristics of wool.

[0004] Currently, wool fabrics are popular in the market for their excellent warmth retention and comfort, but they are deficient in terms of wear resistance, wrinkle resistance and water resistance. Functional fabrics such as polyester and nylon have good physical properties but often lack the natural comfort of wool. Existing composite technologies often have problems such as complex processes, high costs or burdens on the environment. Therefore, technicians in this field provide a composite technology of wool and functional fabrics to solve the problems raised in the above background technology. Summary of the invention
