Introduction

LJ Special Products are developed by shaping shatteres cotton by the wet vacuum suction filter method. Afterdrying and calcination, the compressed cotton is then made into various fiber products of different densities,specifications, models and properties, according to customer's requirements. With our sophisticated productionequipments and steady raw material supply, we provide special products catering for the complex thermalengineering requirements of different customers. In addition, all products are so elaborately made that each can beconsidered as a fine and marvelous piece of artwork.
