Definitions
- a nonwoven fabric of the present invention is a spun-bonded nonwoven fabric including a monocomponent fiber including a copolymerized polyester based resin in which 5 weight % or higher and 40 weight % or lower of a polyethylene glycol is copolymerized with a polyester based resin.
- the spun-bonded nonwoven fabric is characterized in that a ⁇ MR of the spun-bonded nonwoven fabric is 0.5 % or higher and 15% or lower.
- the bending resistance in the present invention is calculated according to a "6.7.3 41.5° Cantilever Method" of "6.7 Bending Resistance” of "General Nonwoven Fabric Testing Method” of JIS L1913: 2010.
- a calculation method will be described. First, five test pieces each measuring 25 mm in width by 150 mm are sampled. Each test piece is placed on a horizontal table having a slope of 45° such that its short sides are aligned with a base line of a scale. Next, the test piece is manually slid along the slope. As soon as a center point of one end of the test piece touches the slope, the moving length of the position of the other end is read by the scale. Such moving lengths are measured as to the both sides of the five test pieces. An average value calculated from the moving lengths is used as the bending resistance in the present invention.
- Bending rigidity and bending return property were measured by use of "KES-FB2" made by Kato Tech Co., Ltd. as a bending tester.
- Copolymerized polyethylene terephthalate in which the number-average molecular weight and the copolymerization amount of contained polyethylene glycol were 5,500 and 12 weight % was melted by an extruder.
- the yarns were pulled and drawn by compressed air from a rectangular ejector having an ejector pressure of 0.30 MPa, and then collected on a moving net.
- a nonwoven fiber web composed of copolymerized polyester filament fibers was obtained.
