Horseshoe-type bulk plastic composite non-woven cloth and manufacturing method and application thereof

Abstract

The invention provides horseshoe-type bulk plastic composite non-woven cloth and a manufacturing method and application thereof. The composite non-woven cloth comprises a hot-air non-woven cloth layer or a melt-blown non-woven cloth layer, and a spun-bonded non-woven cloth layer arranged on the upper surface of the hot-air non-woven cloth layer or the melt-blown non-woven cloth layer in a laminated mode; the spun-bonded non-woven cloth layer is a polypropylene fiber layer, multiple blocky bulk protrusions which are the same in size and are arrayed at equal intervals are arranged on the surface of the spun-bonded non-woven cloth layer in a protruding mode, correspondingly, and grooves corresponding to the blocky bulk protrusions are formed in the surface of the hot-air non-woven cloth layer or the melt-blown non-woven cloth layer; the composite non-woven cloth is in a horseshoe shape, and the side where the spun-bonded non-woven cloth layer is located faces inwards. The composite non-woven cloth is used for manufacturing a surface layer of an infant paper diaper, is good in elasticity and handfeel, soft, comfortable, environmentally friendly and nontoxic and does not stimulate the skin.

Description

technical field [0001] The invention belongs to the field of health care and medical equipment, and is used to manufacture the surface layer of baby diapers. Specifically, it relates to a composite nonwoven material, especially a horseshoe-shaped expanded plastic composite nonwoven fabric, its manufacturing method and application. Background technique [0002] Non-woven materials (Nonwovens), also known as non-woven fabrics, non-woven fabrics, non-woven fabrics, non-woven fabrics or non-woven fabrics. Non-woven technology is becoming an indispensable and important means of providing new fibrous materials. It is an emerging branch of the material industry. No matter in many fields such as aerospace technology, environmental protection, agricultural technology, medical health care or people's daily life, Non-woven new materials have become an increasingly important product. The nonwoven industry is known as the "sunrise industry" in the textile industry. [0003] In recent y...

Problems solved by technology

However, the fiber fineness of the upper and lower layers of the nonwoven fabric obtained by this method is too high, resulting in excessive density after compounding, which still affects the air permeability of the entire double-layer nonwoven fabric.
