Description
Technical Field
The invention relates to the technical field of polyformaldehyde textiles, and particularly relates to a polyformaldehyde fiber finishing liquid, a finishing method and a polyformaldehyde blended fabric.
Background
Polyoxymethylene Fiber (Polyoxymethylene Fiber) is a synthetic Fiber prepared by spinning Polyoxymethylene (POM). Polyoxymethylene is a polymer containing-CH in the molecule2The linear high-density crystalline high polymer of the O-chain link has excellent physical and mechanical properties, excellent alkali resistance, chemical corrosion resistance, thermal stability and other properties, and wide application prospect. At present, the most common preparation method of polyoxymethylene fibers at home and abroad is a melt spinning method, and the polyoxymethylene fibers prepared by the method have the advantages of good size stability, wear resistance, solvent resistance and seawater invasion resistance, and also have excellent quick-drying and cool feeling properties.
However, because the polyformaldehyde fibers have low softness, poor air permeability and poor thermal comfort, the application of the polyformaldehyde fibers in the textile field is greatly limited. The comfort of the garment includes: heat and moisture comfort, contact comfort and visual comfort. The heat and moisture comfort is mainly used for adjusting the heat and moisture transfer performance between a human body and the environment and creating a good and comfortable environment for the human body; the contact comfort refers to the comfort when the clothing is in contact with the human body; the visual comfort mainly aims at meeting the requirements of consumers according to the style, the color and the like of the fabric. The thermal-wet comfort and contact comfort of the garment are key factors determining the comfort of the textile. Therefore, how to improve the softness and wearing comfort of the polyoxymethylene fiber is a research focus in the textile field at present. The fabric can be finished to a certain extent to improve various performances of hydrophobicity, handfeel, antistatic property and the like of the fabric, but because the polyformaldehyde fiber has a regular molecular structure, higher cohesive energy density, higher crystallinity up to more than 70%, a lower amorphous area proportion, an unbranched chain structure and a lack of active groups on the surface, the polyformaldehyde fiber has lower chemical reactivity and the finishing agent is not easy to finish on the polyformaldehyde fiber. Therefore, there are few reports on how to improve the comfort of polyoxymethylene fibers.
