Problems solved by technology

However, polypropylene fiber is not light-resistant, and the material can only be used at room temperature. The material cannot be sterilized by ultraviolet light or high temperature when used, and the product feels stiff and not comfortable.
These all seriously limit the application and development of traditional SMS nonwoven materials
[0004] Chinese patent CN103774342A discloses a soft nonwoven fabric and its manufacturing method. The material produced by this method is a single spunbonded material. The material has low strength when the grammage is low, and the material can only be used at room temperature and is not light-resistant. It cannot be used for ultraviolet disinfection and high temperature disinfection, and there are many restrictions on the application in the medical and health field

Abstract

The invention relates to a soft high-strength terylene SMS composite non-woven material. The soft high-strength terylene SMS composite non-woven material is in a three-layer structure. The structure comprises a modified terylene spun-bonded non-woven material on an upper layer and on a lower layer, and a modified terylene meltblown non-woven material on a middle layer. The surface density of the soft high-strength terylene SMS composite non-woven material is 20-100 g / m<2>, longitudinal strength is 40-200 N / 5cm, longitudinal bending rigidity is 0.1-1 cN.cm, horizontal strength is 60-300 N / 5cm, and horizontal bending rigidity is 0.2-1.5 cN.cm. The soft high-strength terylene SMS composite non-woven material has excellent mechanical property and relatively high hydrostatic pressure. In addition, the invention also provides a manufacturing method for the soft high-strength terylene SMS composite non-woven material.

Description

technical field [0001] The invention belongs to the field of nonwoven materials, and in particular relates to a soft and high-strength polyester SMS composite nonwoven material and a preparation method thereof. Background technique [0002] In recent years, the output of SMS non-woven materials has been increasing, and the sales market has become wider and wider. Among them, the growth of the share in the field of medical protection and the emergence of its importance are particularly eye-catching. With the outbreak of SARS in 2003 and the rampant epidemic of influenza A in 2009, people's awareness of prevention has been continuously strengthened. Now SMS nonwoven materials have been recognized and accepted by more and more people as materials for medical protection. [0003] At present, the raw materials of SMS composite nonwoven materials that can be seen in the market are basically polypropylene. The moisture regain of polypropylene is zero, and the crystallinity is high,...
