Description

A functional multi-color coated trademark tape based on thermally expanded microspheres and its preparation process

Technical field

The present invention relates to the technical field of layered trademark tapes, and in particular to a functional multi-color coated trademark tape based on thermally expanded microspheres and its preparation process.

Background technique

Trademark tape refers to a small piece of fabric used as a symbol of textile products. Each piece of fabric has brand name, manufacturer, country name, specifications and other marks on it. The size depends on the needs. There are two types of trademark tapes: printing and jacquard. Printed trademark tapes are usually made of cotton yarn, high-count cotton yarn, polyester yarn, nylon yarn or rayon as the warp and weft lines of woven fabric, hand-torn fabric, or non-woven fabric as the base material. After subsequent calendering or coating finishing, it is cut into small-sized finished products and then printed by a tape label printing machine. Most of the existing trademark tapes are black and white. With the diversification of textile products and the upgrading of equipment, the market's demand for the color of coated trademark tapes has begun to highlight, and higher softness and washability of trademark tapes have also been proposed. Require.

By evenly coating one or more layers of resin slurry on the base fabric to fill the pores of the base fabric and giving the trademark tape good flatness and printability, it is called a coated trademark tape. The coating surface is usually divided into wet coating and solvent-based dry coating. This patent describes a solvent-based dry coating. Dry coating is divided into water-based resin slurry coating and oil-based resin slurry coating. Water-based resin slurry uses water as the solvent and is environmentally friendly, but the coating has poor washing fastness; oil-based resin slurry coating has excellent effect. It is resistant to water washing, but because the resin contains organic solvents such as DMF and toluene, it is harmful to the environment and is being gradually replaced.

Existing dry coating products cannot satisfy high softness and high wash resistance at the same time. In addition, the development of multi-color trademark tapes cannot meet market demand.

Thermal expansion microspheres are thermoplastic hollow polymer microspheres, consisting of a thermoplastic polymer shell and enclosed liquid alkane gas, with an average diameter ranging from 10 to 50 μm. When heated, the gas pressure within the shell increases and the thermoplastic shell softens, resulting in a significant increase in the volume of the expanded microspheres. When cooled, the expanded microsphere shell hardens again and has a fixed volume. It has stable expansion properties and high resilience, and has been used in many fields such as papermaking, tapes, automotive coatings, and printing inks.

Currently, there are no patents or literature reports on the application of thermally expanded microspheres to coated trademark tapes.
