Binding materials include bookbinding materials, bonding materials and binding materials. There are many types of modern binding materials, dozens of kinds of knowledge, and a wide range of knowledge, including animals, plants, chemical fibers, synthetic resins, minerals and so on. Here are some simple introductions to some of the new materials that have been used in recent years.
1. Cover material
The value and grade of books are directly related to the selection of cover materials. Among them, the pros and cons of cover materials are dominant. The requirements for cover materials in the processing of modern books are different from those in the past. Most of the original hardcover covers are only coated with paper and lacquer. Now there are many additions, such as PVC coatings, resin impregnated papers, impregnations. There are more than ten kinds of resin paper composite materials, leather and textiles coated with pattern paper, fabric and paper.
The variety of cover materials has increased, which has opened up the horizons of the designer of the post, which has increased the choice of the book's decorative materials, opening up new paths for new books and good books, and promoting the improvement of post-press binding technology. .
2, ring material
The lining materials used in hardcover books in the past few decades are offset paper and partial coated paper. These papers are used for strong hygroscopicity of the lining, and the lining of the backing and the book core are easy to wrinkle. Most hardcover books now use resin-impregnated paper as a ring liner. The paper is subjected to resin soaking, the strength of the paper, the fastness is increased, the hygroscopicity is lowered, and there are hundreds of varieties, patterns, and colors, which can be arbitrarily selected, and is the best modern ring lining variety.
3, bonding materials
With the change of the packaging materials, the original vegetable flour paste and the animal bone glue are far from being able to adapt to the bonding of a new generation of decorative materials. In recent years, with the development of the chemical industry and the need to increase the number of materials, the bonding materials are converted into artificial synthetic resins by animals and plants. Such as paper, cardboard and other polyvinyl acetate latex (PVAC), polyvinyl alcohol (PVA), 107 glue, etc., paper-type composite of PVAC and paper vinyl acetate-vinyl emulsion (VAE), adhesive film paper Adhesives (acrylic and styrene copolymers), high-temperature melting hot melt adhesives (EVA), etc., provide a wide range of choices for the bonding of modern decorative materials, and will not be sticky due to book binding processing. The binding quality is not suitable and various binding quality problems occur.
There are many types of post-press binding materials, there are hundreds of them, and there are only six types of bonding materials in more than 20 types. This article only describes some of the more varied types in recent years.
Post-press binding technology is actually the packaging technology of books and periodicals. The quality is ultimately determined by the packaging effect, which is the overall concept of a book or the importance of the finished process. This is a new concept of contemporary post-press finishing technology and a new topic for the binding industry. Post-press binding is no longer a book-binding book, but a technical and artistic process. The knowledge involved is quite extensive. If you don't carefully understand its current status, don't know its characteristics. Can not adapt to modern needs.
