Problems solved by technology

At the same time, when the accumulated static electricity is higher than 50 V, it will cause sparks due to discharge and cause a fire. Especially for medical and nursing places, due to the presence of a large number of flammable and explosive substances such as ether and cyclopropane, the generation of static electricity will not only cause explosions and fire, but also have adverse effects on precision electronic equipment

Abstract

The invention provides an antistatic finishing process of a chemical fiber fabric. The antistatic finishing process comprises the following steps of pretreatment, preforming, dyeing, drying, padding, drying, baking, forming, calendering and winding. According to the antistatic finishing process, the chemical fiber fabric is firstly refined and then subjected to alkali weight reduction treatment during the pretreatment, so that the comfortable property of the chemical fiber fabric is enhanced, the integral property of the chemical fiber fabric is enhanced and the stability of the chemical fiber fabric is enhanced under the condition that the chemical fiber fabric is not damaged, and the stability of subsequent steps, namely the dyeing, the padding, the forming and the calendaring is guaranteed; an antistatic agent is added to the padding procedure, so that the antistatic property of the chemical fiber fabric is effectively improved, and the waterproof property and softening property of the chemical fiber fabric are both greatly enhanced through added waterproof agent and softener, the chitosan is also added to the padding procedure, the chitosan is a high-molecular substance with natural antibacterial and deodorant property, is safe and environmentally friendly, can also be used as the antistatic agent, and the antistatic property and antibacterial and deodorant property of the chemical fiber fabric are all greatly enhanced after the chitosan is added.

Description

technical field [0001] The invention relates to the chemical fiber field, in particular to an antistatic finishing process for chemical fiber fabrics. Background technique [0002] Chemical fiber fabrics have the advantages of high elasticity, crispness, and quick drying, but they are prone to static electricity. During the fabric processing, they are easy to attract each other, entangle, fluff, and become dirty after absorbing dust. They are easy to absorb dust and pollen and cause allergies; Tends to cling to metal bodies causing fabric to wrap around the drum. According to the health organization, static electricity will affect the metabolism of the human body, causing dizziness, irritability, and the loss of vitamin C, making people nervous and depressed. At the same time, when the accumulated static electricity is higher than 50 V, it will cause sparks due to discharge and cause a fire. Especially for medical and nursing places, due to the presence of a large number of...
