[0002] As people pay more and more attention to environmental protection and sustainable development, natural fibers are increasingly used in the textile field. As a natural plant fiber, pineapple fiber has certain advantages, such as being biodegradable and abundant in sources. It is widely used in clothing, home decoration or industrial fields. At present, in the production process of traditional pineapple fiber blended fabrics, the material of the fabric is single, which will result in low strength, poor spinnability and rough feel of the fabric; the process of extracting pineapple fiber from pineapple leaves is relatively complicated, which requires a lot of manpower and time; multiple processes such as scraping and degumming are required in the extraction process, and the separation of fibers is difficult, and problems such as fiber breakage and inconsistent lengths are prone to occur; in this way, during production, it is easy to cause pilling of the fabric, and the traditional pineapple fiber blended fabric is prone to fading during use, which will cause the fabric to break and become brittle, causing the fabric to break; When traditional fabrics are blended, the bonding strength between fibers is not ideal, and stratification is prone to occur, affecting the overall quality of the fabric. In terms of performance optimization, some blended fabrics fail to give full play to the advantages of pineapple fibers. Characteristics such as moisture absorption and breathability are not well reflected in the blended fabrics. At the same time, some shortcomings of other fibers may also be introduced, such as the static electricity problem of synthetic fibers or the easy shrinkage problem of some natural fibers.
