Problems solved by technology

However, in the traditional finishing process, most of the pulp will immediately penetrate into the non-woven fabric, and a small part will stand on the surface of the non-woven fabric.
During the drying process, due to poor thermal stability, the pulp will continue to penetrate into the non-woven fabric. After drying, there will still be fiber hairs on the surface of the non-woven fabric. Affect the quality of non-woven fabrics

Abstract

The invention discloses a spraying process of a multi-colored non-woven fabric. The spraying process specifically combines water-in-water multi-colored coating, a multi-colored coating spraying process and a non-woven fabric surface after-finishing process; the specific process flow comprises the steps of preparing a water-in-water multi-colored spraying paste, spraying the paste, and drying and shaping the non-woven fabric. The preparation of the water-in-water multi-colored spraying paste comprises the following four steps: preparing a basic paste, mixing color, granulating and finally adding emulsion and an auxiliary agent so as to prepare the water-in-water multi-colored spraying paste. The multi-colored non-woven fabric finished by the production process above has a flat surface and can form a film continuously, without exposing fiber yarn ends; no paste permeates into the non-woven fabric so that the non-woven fabric keeps a loose and empty state and has a very good hand feeling. The surface stain removing and stain preventing performances of the multi-colored non-woven fabric are greatly improved, and the firmness, abrasion resistance and the like of the multi-colored non-woven fabric are also greatly improved.

Description

Technical field: [0001] The invention relates to a production process of non-woven fabrics, in particular to a spraying process of colorful non-woven fabrics. Background technique: [0002] Non-woven fabrics have been widely used in many fields. There are also many types of non-woven fabrics, such as spunlace, acupuncture, heat-bonding and so on. Some non-woven fabrics can be used directly without post-finishing, and most non-woven fabrics can be used after post-finishing or functional finishing, such as leather, filter equipment, cleaning cloth, wallpaper, etc. There are many ways to finish non-woven fabrics, such as dipping, printing, coating, laminating, foam printing and coating foaming. There are also cooperating finishing, such as dipping and then printing, first coating and then printing, etc. In short, in the non-woven production practice, people have summarized and explored more and more non-woven finishing methods. [0003] Non-woven fabrics are relatively hair...
