Fibrous product |
摘要 |
A resilient, thermally bonded, non-woven fibrous batt having a uniform compression modulus in one plane which is more than the compression modulus measured in a direction perpendicular to that plane, and a substantially uniform density across its thickness is obtained by preparing a batt comprising at least 20% by weight of crimped and/or crimpable conjugate fibres having or capable of developing a crimp frequency of less than 10 crimps per extended cm. and a decitex in the range of 5 to 30. The batt is thermally bonded by subjecting it to an upward flow of a fluid heated to a temperature sufficient to heat the batt to a temperature in excess of the softening temperature of the low softening component but below the softening temperature(s) of the other component(s) of the conjugate fibre to effect inter-fibre bonding. The thermally bonded batt is then cooled by an upward flow of cool air.
