The present invention relates to a nonwoven composite and an apparatus for producing the same, which can improve the quality of the composite.

In general, non-woven fabric is a non-woven fabric made of a felt shape by arranging the fibers in parallel or in an opposite direction without bonding the woven process and bonding with a synthetic resin adhesive. Cotton, viscose rayon, synthetic fibers are used as raw materials for nonwoven fabrics.

Nonwoven fabrics are submerged and dry depending on the processing method. Immersion is also called papermaking (抄紙 式), and the fibers are put in a synthetic resin glue, wetted, dried and heat-treated, similar to paper. Drying is made of fibers made of thin cotton, spouted with synthetic resin and dried by heating.

Nonwoven fabric can replace natural pulp or cotton using synthetic fibers, and it is used as disposable absorbent products such as sanitary napkins, disposable diapers and adult incontinence products, various disposable cleaning cloths used for cleaning, medical sheets, and waterproof packaging materials. In order to improve the properties such as absorbency, waterproofness, strength improvement, etc., it is manufactured and used as a composite mixed with additional materials.
