Abstract

The invention discloses a production process of sponge-structured high-elasticity non-woven three-dimensional cotton, which comprises the following steps of: blending high-elasticity and low-melting-point modified polyester short fibers, thermoshrinking modified polyester short fibers and other fibers according to a ratio and processing the mixed fibers by using an opener; delivering the processed materials into a cotton feeding machine through a cotton conveying fan; combining by a feeding combing machine of the cotton feeding machine to form a fiber web with a continuous structure; feeding the fiber web into a vertical web-laying molding machine for vertical molding treatment; conveying the obtained product into an oven for thermal molding by an oven conveying belt; cooling, setting, molding and winding strips to obtain the sponge-structured high-elasticity non-woven three-dimensional cotton. The longitudinal and transverse tension and the density uniformity of the three-dimensional cotton produced by the production process are both similar to those of sponge, and the three-dimensional cotton is suitable for shaped shearing processing such as splitting and chipping, has a structure similar to that of the sponge, has high rebound resilience, compression resistance and air permeability, can replace a foaming polyurethane material and can be applied in many fields in which the foaming polyurethane material cannot be applied.

Description

technical field

[0001] The invention belongs to the field of non-woven technology, and in particular relates to a production process of sponge-like structure and high elasticity non-woven three-dimensional three-dimensional cotton. Background technique

[0002] Foamed polyurethane materials such as sponges and foams are widely used in the world today. Items made of foamed polyurethane materials involve all aspects of our lives. Foamed polyurethane material has excellent performance in many aspects, but as we all know, polyurethane material is not an environmentally friendly material. Polyurethane material is easy to decompose. The best foamed polyurethane material will start to decompose after six months. After decomposition, it will form gases and substances that are toxic to the environment and human body.

[0003] In addition, foamed polyurethane materials are extremely flammable. Since polyurethane materials are widely used in home materials, such as sofas, Simmons, and...
