Production process of polyester wadding or non-glue cotton

Abstract

The invention discloses a production process of polyester wadding or non-glue cotton, comprising the following steps of: opening, cotton feeding, carding, glue spraying, drying, cooling, high pressure cotton sucking and automatic cotton rolling, and finally the polyester wadding or non-glue cotton finished product is obtained; in the glue spraying process, a polyester wadding bonding agent and a functional finishing agent are applied onto the polyester wadding or non-glue cotton in a spraying manner, wherein the polyester wadding bonding agent is polyvinyl acetate or polyvinyl acetate bonding agent, and the functional finishing agent is one or more than one of antibacterial agent, mothproofing agent, anion agent and nutrient. The polyester wadding or non-glue cotton disclosed by the invention is formed by the steps of carding polyester wadding or non-glue cotton into nets, laying the nets, spraying the functional finishing agent in all directions and drying in a drying oven and has a technological function. The obtained product is fluffy, washable and has technological functions (antibiosis, mothproofing and nutrition enhancing functions and the like), and the process can be used together with a cotton polishing process.

Description

technical field

[0001] The invention relates to a production process of glued cotton or non-glued cotton, in particular to a production process of sprayed glued cotton or non-glued cotton with scientific and technological functions (antibacterial, anti-mite, nutrition addition, etc.). Background technique

[0002] Sprayed cotton, also known as sprayed cotton, is a kind of non-woven fabric. The principle of the formation of the sprayed cotton structure is to spray the adhesive on both sides of the fluffy fiber layer. Due to the certain pressure during spraying and the lower vacuum The suction force when absorbing liquid, so the adhesive can also penetrate into the inside of the fiber layer, and the fiber layer after spraying the adhesive is then dried and cured, so that the intersection points between the fibers are bonded, but not bonded to each other Fibers still have considerable degrees of freedom. At the same time, in the three-dimensional network structure, there a...
