Technical Field

The invention belongs to the technical field of functional fibers, and particularly relates to a manufacturing process of school uniform based on special-shaped polyester functional cool fibers.

Background

Along with the improvement of the life quality of people, the requirement on the comfort of clothes is higher and higher, and the fabric of the clothes is expected to have light weight and good moisture absorption, sweat releasing and quick drying performances. Especially for summer fabricsThe heat-moisture comfort performance of cool moisture absorption, moisture absorption and ventilation, moisture conduction and quick drying and the like is obtained. Generally speaking, the light and thin fabric is suitable for being worn in summer, but because the light and thin single-sided weft-knitted fabric has certain curling property and the size stability of the fabric is inferior to that of the double-sided weft-knitted fabric, the weight average of the conventional double-sided weft-knitted fabric is generally 150g/m²Above, the mass is heavy. The existing garment fabric is usually woven by pure cotton fabric or common polyester fiber, although the sweat absorption and ventilation effects of the pure cotton fabric are good, the wet fabric can be attached to the surface layer of the skin to give people a sticky feeling, the wearing comfort level is not high, and the pure cotton fabric can not discharge sweat to the outer layer of the fabric in time after absorbing the sweat, so that the fabric can be quickly dried by the flowing air outside.

The general realization methods of the contact cool feeling terylene fabrics in the market at present are as follows:

firstly, mixing a substance with a cooling effect with a polyester slice, spinning to form a filament with a cooling effect, such as jade fiber, and further preparing the fabric; secondly, adding a cool feeling auxiliary agent such as xylitol cool feeling auxiliary agent in the fabric after-finishing processing to obtain a cool feeling effect; thirdly, the yarn hairiness is reduced by adopting a compact spinning mode, so that the warm-keeping effect is reduced and the cool feeling effect is obtained.

The knitted fabric obtained by adding the cool auxiliary agent in the fabric after-finishing processing has poor washing fastness, the cool effect of the fabric after being washed for many times is weakened, and in addition, the cool auxiliary agent can interact with other auxiliary agents in the after-finishing processing process to cause unobvious effect or weakened effect.

Meanwhile, fibers with cool feeling effects such as jade fibers and the like are added in a large amount in order to achieve sufficient cool feeling, so that the fiber strength is poor, the comfort is insufficient, and the problems of powder falling, peculiar smell and the like exist; and the cooling effect is insufficient when the addition amount is reduced.
