Embodiment 1

Embodiment 2

(3) the fabric in the step (2) is first calendered by oil surface calender, and the pressure is at 8 kilograms, and 200 ℃ of temperature are calendered.

The speed of the locomotive is 40 m / min, and the calendering is performed for 3 times continuously; then the calendering is carried out by a mirror calender, the pressure is controlled at 8.5 kg, and the temperature is 150

℃, the speed of the calender is 60 m / min, and the calender is continuously calendered twice to obtain a cotton fabric with durable luster.

After embodiment 1 and embodiment 2 are implemented, data index is as shown in table 1.

Abstract

The invention discloses a formaldehyde-free cotton fabric processing method with durable luster, comprising: (1) after the cotton gray cloth is singeed, desized, dyed (or printed), the mixture of acrylamide and methacrylamide is used to Cotton fabric is grafted, and after the grafting reaction is completed, it is washed with water; the fabric is soaked in water-based polyurethane finishing solution, and then dried after soaking in the finishing solution; the fabric is first calendered through an oil calender, and then passed through a mirror calender Calendering results in a cotton fabric with a durable luster. The fabric obtained by this method has no formaldehyde and has better durable luster. The process is convenient to operate, high in feasibility, and the raw materials used are simple and easy to obtain. The auxiliary agent adopted in the present invention has no formaldehyde or potential formaldehyde release problem in the whole process, and the technological process is simple and easy for industrial implementation.

Description

Formaldehyde-free and durable glossy cotton fabric processing method technical field The present invention relates to textile technical field, be specifically related to a kind of formaldehyde-free cotton fabric processing method with durable gloss. Law. Background technique After the cotton fabric is finished by calendering, the color of the fabric is more and more gorgeous, the pattern is pleasing to the eye, and presents a soft and beautiful appearance The luster is a popular fashion fabric in the market. In the early calendering finishing, starch or polyvinyl alcohol was used as calendering resin. By adjusting the amount of additives, calendering temperature, cloth surface humidity and other process factors, the calendered fabric shows a bright effect, but the use of this technology The luster of the calendered fabric has poor washing resistance, and the luster basically disappears after washing, so the early calendered fabric is mainly used for interior decorat...
