Abstract

The invention provides a manufacturing method of an environment-friendly sheath-core fibrilia with nice feeling. The sheath-core fibrilia comprises a core layer of fibrilia, wherein the fibrilia is treated with silane coupling agent and the external of fibrilia is covered with a layer of polylactic acid. The manufacturing method thereof comprises the steps of: A) cutting the polylactic acid into pieces and drying, dipping the fibrilia into silane coupling agent and then drying, B) conjugating spinning the polylactic acid pieces and the dried fibrilia from the step A) with a conjugating spinning machine to make into sheath-core conjugating spinning component, C) orderly winding, drawing and forming the sheath-core conjugating spinning component to make into sheath-core fibrilia, D) orderly winding and packaging the sheath-core fibrilia. The sheath-core fibrilia of the invention is environment-friendly and has a nice feeling, meeting the demand of people on fiber. The manufacturing method thereof is simple, useful and highly efficient.

Description

technical field

[0001] The invention belongs to the technical field of chemical fiber production, and in particular relates to a production method of hemp fiber. Background technique

[0002] Hemp fiber refers to the fiber obtained from the stems, leaves, and leaf sheaths of hemp plants that can be used for textiles. It has good moisture absorption and ventilation functions, fast heat transfer and heat conduction, cool and crisp, sweating is not close to the body, light in texture, Strong, insect-proof and mildew-proof, but due to its poor elasticity, poor wrinkle resistance and abrasion resistance, and itching, the development of hemp fiber varieties has been limited. At present, hemp fiber and non-environmentally friendly chemical fiber are blended into products. The produced hemp fiber is relatively rough and has a relatively low count. When in use, it needs to be treated with surface burrs, which increases the complexity of the process. Contents of the invention [00...
