Technical Field

the invention relates to the technical field of polyester modification, in particular to a single-sided hydrophilic modified polyester fabric and a preparation method thereof.

background

Polyethylene terephthalate, commonly known as polyester, is widely used in textile materials due to its excellent physical and chemical properties.

for example: the terylene fabric has higher strength and elastic recovery capability, so the terylene fabric is firm and durable, and is crease-resistant and non-ironing. The terylene is the fabric with the best heat resistance in the synthetic fiber fabric, has thermoplasticity, can be made into a pleated skirt, and has lasting pleating. The light resistance of the polyester fabric is better, and the sun-proof capability of the polyester fabric is better than that of a natural fiber fabric except that the polyester fabric is poorer than that of acrylic fiber. Especially, the sun-proof capability behind the glass is very good and almost comparable with that of acrylic fiber. The polyester fabric has good resistance to various chemicals. The damage degree of acid and alkali is not large, and the product is not afraid of mould and worm damage. After washing, the fabric is extremely easy to dry, the wet strength is hardly reduced, the fabric does not deform, and the fabric has good washing and wearing performance.

However, the polyester fabric has poor hygroscopicity due to poor hydrophilic performance, and is not applicable to sports clothes, bed sheets and the like because of stuffy feeling of wearing in summer.
