Polyester yarn reflective cloth bonding technology

Polyester reflective fabric is a kind of functional fabric with good reflective effect. It is widely used in traffic safety, outdoor sports equipment and night workplaces. In order to improve the quality and performance of polyester reflective cloth, it is necessary to glue it. This paper introduces the bonding process of polyester reflective fabric.

The bonding process of polyester reflective fabric is mainly divided into four steps: pretreatment, adhesive coating, drying and curing.

The first is the pre-processing phase. Polyester reflective fabrics need to be purified before bonding to remove surface impurities and contaminants. This can be done by washing, bleaching, dyeing, etc. Washing can remove dirt and oil, bleaching can remove color, dyeing can stain polyester reflective cloth, so that it has a better appearance.

Next comes the adhesive coating phase. The surface of polyester reflective cloth is coated with a layer of adhesive, commonly used adhesives are polyurethane, copper oxide and so on. The selection of adhesive should be based on the thickness, softness and bonding strength of polyester reflective cloth requirements to choose. When coating, it is necessary to ensure that the adhesive is evenly coated on the surface of the polyester reflective fabric and does not fall off.

And then the drying phase. After coating, polyester reflective cloth needs to be dried. The purpose of drying is to make the adhesive form a uniform film on the surface of the polyester reflective cloth, and obtain a good bonding effect. There are many drying methods, commonly used are natural drying and drying. Natural drying takes longer, while drying can be done quickly. In the drying process, it is necessary to pay attention to the control of temperature and humidity to avoid excessive or insufficient drying on the quality of polyester reflective cloth.

The end is the curing stage. Curing is a very important step in the bonding process of polyester reflective fabric. The purpose of curing is to enable the adhesive to form a strong connection on the surface of the polyester reflective fabric. There are two common curing methods: hot curing and cold curing. Hot curing is to cure the adhesive quickly by high temperature, while cold curing is to cure the adhesive slowly at low temperature by adding curing agent.

In short, the bonding process of polyester reflective cloth is a complex and critical process, which requires multiple steps such as pretreatment, adhesive coating, drying and curing. Through proper operation and strict quality control, high quality polyester reflective fabrics can be obtained.
