The invention discloses a bio-based all-cotton
fluoride-free waterproof fabric for a high-performance sports cap and a preparation method of the bio-based all-cotton
fluoride-free waterproof fabric, and relates to the field of biochemical treatment and preparation of
textile fabrics. The garment body is made of fabric, the fabric comprises a bio-based all-cotton base material, a compound
enzyme treatment layer, a bio-based modified layer and a
fluoride-free waterproof layer, compound
enzyme is composed of
cellulase,
pectinase and
lipase, the
raw material of the bio-based modified layer is bio-based
polyol, and the
raw material of the fluoride-free waterproof layer is a
polycaprolactone fluoride-free waterproof agent. The preparation method comprises the following steps: firstly cleaning and
drying the base material, then carrying out compound
enzyme biochemical treatment and bio-based
polyol grafting reaction, and finally padding and curing through a fluoride-free waterproof agent. The fabric and the method meet the fluoride-free and environment-friendly requirements and meet the use requirements of high-performance sports caps, and the comprehensive performance of the fabric is improved by means of a biochemical treatment process.
