Abstract

The invention discloses a cotton fabric hydrophobic finishing method based on an acrylics-modified silicon ball-electron beam technology, and belongs to the field of functional textiles. The method disclosed by the invention adopts an electron beam radiation technology, the method can react under room temperature, the energy consumption is low, an initiator does not need to be added, the reaction time is short, and the production cost can be obviously reduced; long-chain acrylic acid can be selected and used as monomers, so that the free energy of fabric surface can be obviously reduced, and meanwhile the environment-friendly problem easily generated by a fluorine-containing reagent is avoided; the roughness of the fabric surface can be improved through the addition of modified silicon dioxide, and meanwhile the problem, such as low adhesion caused by pure physical absorption, of silicon dioxide silicon balls is avoided. According to the method in which the lower surface energy is combined and the fabric surface roughness is improved, textiles with high hydrophobic performance are obtained through an electron beam one-step radiation graft polymerization technology.

Description

technical field [0001] The invention relates to a method for hydrophobic finishing of cotton fabric based on acrylate-modified silicon ball-electron beam technology, which belongs to the field of functional textiles. Background technique [0002] In recent years, with the improvement of people's level, textiles have gradually transformed from simple warmth retention to comfort and functionality, expanding the application value of textiles. Hydrophobic fabrics have a broad application market, such as outdoor sportswear, protective clothing, etc. It is of inestimable economic significance to develop a simple method for fabric hydrophobic preparation. [0003] Cotton fabrics are favored by people for their comfort and breathability. However, due to the numerous hydroxyl groups in the molecular structure of cotton fiber, it is highly hydrophilic and easily polluted by water stains. Hydrophobic finishing of cotton fabrics can effectively avoid the above problems. Reducing the ...
