Abstract

The invention provides a high-barrier spun and melted novel breathable material. When the gram weight is 25 gsm, hydrostatic pressure resistance is 390-410 mmH2O, air permeability is 450-550 L / m<2> / S,MD strength is 65-75 N / 5 cm, CD strength is 28-35 N / 5 cm, MD elongation is 40%-80% and CD elongation is 40%-80%. The invention also provides a preparation method of the novel breathable material. Themethod comprises steps of material selection, melt extrusion, fiber drafting and hot rolling treatment. S-layer fine denier fiber with fineness of 1.5-1.8 denier is obtained through fiber drafting; M-layer fine denier fiber has fineness of 2-4 micrometers, and water repellency and filling power of fiber are kept. The invention also provides an application of the novel breathable material in diapers and the breathability of the diapers is substantially improved.

Description

technical field [0001] The invention belongs to the technical field of nonwoven fabrics, and relates to a new high-barrier spunmelt-mixed breathable material, in particular to a high-barrier spunmelt-mixed breathable new material, a preparation method and an application thereof. Background technique [0002] Highly breathable, high barrier non-woven fabric, which can be directly used as the bottom film material of diapers. At present, in order to reduce leakage, PE film composite non-woven materials are mostly used in the market as the bottom film of the absorbent core of disposable products. Due to the good water blocking performance of the PE film base film during use, it has poor air permeability and affects moisture drainage, which can easily cause redness of the baby's skin, cause diaper rash, and affect the health of the baby's skin. High-barrier non-woven fabric is used as the base film, which can eliminate the use of PE film, greatly improve the air permeability and...
