Problems solved by technology

Because the particles of general water-absorbing polymers are relatively large and repel other fibers, it is easy to fall off when dry
Moreover, due to the mixing of water-absorbing polymer fibers, the strength of the non-woven fabric is reduced, which affects the performance of the non-woven fabric.

Abstract

The invention relates to a non-woven fabric and a production method thereof, in particular to a powderless, water-swelling and non-woven fabric and a production method thereof. The powderless, water-swelling and non-woven fabric is applicable to cables and optical fibers or can be also processed into household articles, medical and health material, and the like. The powderless, water-swelling and non-woven fabric is formed by adopting a self-made solution with macromolecular hydroscopicity by high-temperature curing and crosslinking in a fiber saturating and gumming link for producing the non-woven fabric. The invention adopts the self-made solution comprising compounds capable of forming the macromolecular hydroscopicity by the high-temperature curing and crosslinking in the fiber saturating and gumming link in the production technology to form the non-woven fabric with water-swelling function. The non-woven fabric can be directly applied to cables, optical fibers or other civil fields. The invention has simple technology, stable technical performance and excellent waterproof effect.

Description

technical field [0001] The invention relates to a nonwoven fabric and a production method thereof, in particular to a powder-free water-absorbing swelling nonwoven fabric and a production method thereof. Background technique [0002] The requirements for environmental protection in modern production and life are increasingly strengthened. For the treatment of daily oil pollution and wastewater, high-grade cotton-containing paper or non-woven fabrics containing pulp are often used. Due to the large amount of pulp content, these products are often used in the While protecting the environment, it also increases the demand for trees, thus causing indirect damage to the overall natural environment. [0003] For example, cotton rags with good water absorption performance are often used in daily household to clean objects in contact with food and human body. When such rags are reused, a large number of bacteria will be produced, which will cause great harm to the human body. The c...
