Abstract

The invention discloses a super-soft and super-fluffy spun-bonded non-woven fabric and a preparation method thereof. The super-soft and super-fluffy spun-bonded non-woven fabric is prepared from the following raw materials in parts by weight: 55-65 parts of polyethylene glycol terephthalate, 25-32 parts of polyurethane elastomers, 7-10 parts of polyethyleneglycol adipate, 5-7 parts of linear low-density polyethylene, 9-12 parts of metallocene linear low-density polyethylene and 4-6 parts of oxidized polyethylene. According to the super-soft and super-fluffy spun-bonded non-woven fabric, on thepremise that the mechanical property and durability are guaranteed, the softness of the super-soft and super-fluffy spun-bonded non-woven fabric is far superior to that of common PET non-woven fabric, the fluffy comfort degree of the super-soft and super-fluffy spun-bonded non-woven fabric is far superior to that of the common PET non-woven fabric, the air permeability is high and good, the disability is high, and the elasticity is good; the good waterproof performance is achieved; and the comprehensive performance index is excellent, the comprehensive use performance is good, and the marketapplication prospect is wide.

Description

technical field [0001] The invention relates to the technical field of nonwoven fabrics, in particular to a super soft and super fluffy spunbonded nonwoven fabric and a preparation method thereof. Background technique [0002] Non-woven fabrics, also known as non-woven fabrics, are composed of oriented or random fibers. It is called cloth because of its appearance and certain properties. Non-woven fabrics have no warp and weft threads, are very convenient for cutting and sewing, and are light in weight and easy to shape, so they are deeply loved by handicraft lovers. Because it is a fabric that does not need spinning and weaving, it is just oriented or random arrangement of short textile fibers or filaments to form a web structure, and then reinforced by mechanical, thermal bonding or chemical methods. [0003] Non-woven fabric is a kind of non-woven fabric. It directly uses polymer chips, short fibers or filaments to form fibers through airflow or machinery, and then unde...
