08 Mar, 2025 2:29pm
Most of the products in the market belong to acrylate type products. There are two types of cover printing paste: cover printing paste and transparent paste. Cover printing paste is divided into white cover printing paste and color cover printing paste. There are three types of cover printing paste: high elastic strength, medium and low elastic strength. They are composed of adhesive, thickener and titanium white powder. Transparent paste adhesive is the same as white glue. MILANDO printing material manufacturers share the composition and production technology of printing glue for you.
It can be used in the printing of cotton, hemp, viscose, cotton fiber, polypropylene fiber, chlorine fiber and various fiber blended fabrics, as well as leather, artificial leather and other materials. The biggest advantage of colloidal printing process is its wide application, beautiful color and high reduction degree, but its printing process is more complex than water slurry printing process.
(1) The composition of the adhesive can be divided into two categories: one is acrylate copolymer, the other is polyurethane.
Acrylate adhesive has strong adhesion, good fastness and wide application; polyurethane adhesive has good elasticity and excellent hand feel. According to the actual use requirements, the two kinds of adhesives can be mixed to achieve a balance between hand feel, elasticity and firmness. Generally speaking, white glue paste and color printing paste are used for dyed fabrics, and transparent paste is used for white fabrics.
(2) mucilage Technology: the glue is applied to a high degree of seamless mixing of the chemical gel and the dye, and the dye is firmly adhered to the fabric fabric through the gel medium, forming a film with scalability and covering.
(3) Characteristics of the glue product: the glue is in the form of paste or paste under normal temperature, the appearance is milky white, the viscosity is 10000-150000cps, which is non-ionic, pH value is 6-7, solid content is 45% ~ 55%, and the storage period is one year.
