Technical Field
The invention relates to the field of high-grade swimming pool water filtering materials, in particular to a terylene spunbonded non-woven fabric for water filtering of a high-grade swimming pool.
Background
Energy conservation and environmental protection are one of important guiding ideas in social development. The water in the high-grade swimming pool is basically used in a circulating filtration mode, and various new materials are continuously tried, developed and introduced in the field so as to improve the recycling of the water. Because the water of the swimming pool is in direct contact with the human body, the water filtering material of the swimming pool needs reliable antibacterial performance besides the impurity filtering performance and the mechanical performance of the filtering material. Thus, filtration, antimicrobial, stiffness, etc. are all desirable properties for a swimming pool water filtration material.
Nonwovens often possess one or more of the desirable characteristics of water filtration materials, for example, the properties of conventional polypropylene nonwovens allow them to be used in a variety of water filtration configurations, and their flexibility provides a number of benefits to water filtration. However, most common non-woven fabrics have low antibacterial performance level, poor filtering effect, low stiffness and trouble for water filtration operation. The high-grade swimming pool water filtration industry needs more new materials with excellent physical and mechanical properties such as antibiosis, excellent filterability and stiffness. Therefore, the invention provides the spun-bonded non-woven fabric for the water filtration of the high-grade swimming pool to solve the problems.
