Abstract

The invention provides a novel high barrier spunbond ventilating material. When the gram weight of the material is 15 gsm, the anti-hydrostatic pressure is 100-105 mmH2O, the air permeability is 3810-3820 L/m<2>, the MD strength is 30-35 N/5 cm, the CD strength is 15-17 N/5 cm, the MD elongation is 48-58% and the CD elongation is 65-75%. The invention further provides a preparation method of the novel ventilating material. The preparation method comprises material selection, fiber traction and hot rolling treatment. In the fiber traction step, the traction air pressure is 3000-4000 pa, the process air temperature is 16-30 DEG C, the slit width is 20-24 mm and the fineness of the obtained fine denier fibers is 1.5-1.8 denier. The invention further provides application of the novel high barrier spunbond ventilating material in paper diapers. The dehumidifying property is improved and the problems of reddening of skin of babies and induction of diaper rash when the paper diapers are usedare solved while the ventilating property is improved.

Description

technical field [0001] The invention belongs to the technical field of non-woven fabrics, and relates to a high-barrier spun-bonded breathable new material, in particular to a high-barrier spun-bonded breathable new material, a preparation method and an application thereof. Background technique [0002] At present, spunmelt materials (SSMMS / SMS / SMMMS) are mostly used in the market as leak-proof partitions for diapers, pull-up pants, and sanitary napkins. The spunmelt partition has good water-blocking performance, but poor air permeability, which affects the moisture-wicking performance, which can easily lead to redness of the baby's skin, diaper rash, and affect the health of the baby. [0003] The Chinese patent with publication number CN107447372A provides a manufacturing method of SMS-type non-woven fabric, SMS-type non-woven fabric and its application. The addition amount of fluorine-containing masterbatch in the product is 13.5-43.5%, and the addition amount is high. Th...
