Definitions

  • the average diameter of the composite fiber may be 1 ⁇ 50 ⁇ m.
  • a nonwoven fabric laminate having at least two or more layers, of which at least one layer is a nonwoven fabric of the crimped composite fiber is provided.
  • the hydrophilic agent may be a nonionic hydrophilic agent.
  • the nonionic hydrophilic agent may include silicone compounds such as amino group-containing silicone and oxyalkylene group-containing silicone; Polyhydric alcohol mono fatty acid esters such as sorbitan fatty acid ester, diethylene glycol monostearate, diethylene glycol monooleate, glyceryl monostearate, glyceryl monooleate, and propylene glycol monostearate, N-(3-olee Yloxy-2-hydroxypropyl) diethanolamine, polyoxyethylene hydrogenated castor oil, polyoxyethylene sorbit beeswax, polyoxyethylene sorbitansquistearate, polyoxyethylene monooleate, polyoxyethylene sorbitanses
  • Nonionic properties such as quistearate, polyoxyethylene glyceryl monooleate, polyoxyethylene monostearate, polyoxyethylene monolaurate, polyoxyethylene monooleate, polyoxyethylene cetyl ether, polyoxyethylene lauryl ether, etc.
  • Surfactants Or a combination thereof
  • the nonwoven fabric laminate When the article is a diaper, the nonwoven fabric laminate has a hydrophilic agent impregnation amount (OPU: Oil Pick-UP) of 0.7% or less, and thus the durable absorption rate of water when applied to the top sheet layer of the diaper may be 10 sec or less.
  • OPU Oil Pick-UP
  • hydrophilic agent impregnation amount may be calculated according to Equation 1 below.
  • Tensile strength The maximum tensile load was obtained by performing a tensile test under the conditions of a width of 5 cm, an interval of 10 cm, and a tensile speed of 500 mm/min according to KSK 0520 method using a tensile strength elongation device (Instron) measuring equipment.
