The invention discloses a manufacturing method of high-elasticity cotton /
polyurethane knitted fabric. The manufacturing method includes the steps of
raw material preparation, wherein pima cotton and
polyurethane filaments are prepared; the weaving technology, wherein the pima cotton serves as face
yarn, the 40 D Lycra serves as bottom
yarn, and the face
yarn is always located on the front face of the fabric; the preshaping technology, wherein the manufactured fabric is preshaped, the temperature of a shaping
machine is set to be 190-200 DEG C, and the speed of the shaping
machine is 20-25 m / min; the
dyeing technology, wherein the
dyeing process includes pretreatment, cotton
dyeing and aftertreatment technical flow processes; the afterfinish technology, wherein vibrating
drying is carried out after dyeing is completed, the
drying temperature is 130 DEG C, a
softening agent is added after
drying for final shaping, the shaping temperature is 130 DEG C, and the speed is 15-20 m / min. The manufacturing method has the advantages that the manufactured fabric is soft and comfort in handfeel, high in hygroscopicity and gas permeability and ultrahigh in elasticity and resilience and is suitable for manufacturing high-grade knitted underwear and specially functional sports clothes such as a kneecap support, an
elbow support,
waist support and a leotard.
