摘要： High loft, low density nonwoven webs are produced by forming substantially continuous, spunbond, crimped, bicomponent fibers of A/B bilateral morphology in an unheated fiber draw unit. The fibers are then heated and cooled in the absence of impeding forces to achieve maximum crimp in the z-direction and produce a web of lofted material. The resultant material is particularly suitable for use as an insulator. Particulates may be added to the webs if desired.

摘要： High loft, low density nonwoven webs suitable for use in a variety of applications requiring strong fabric layers are produced by forming substantially continuous, spunbond, crimped, bicomponent fibers of crimpable, e.g., side by side or eccentric sheath/core (A/B) configuration which are unheated prior to collection. The fibers are then heated and cooled in the absence of impeding forces to achieve maximum crimp in the Z-direction and produce a web of lofted material of greater uniformity than attained with comparable material whose fibers are drawn by a heated process. The resultant nonwoven material can then be pattern bonded or laminated for additional strength without interfering with the desired loft of the low density nonwoven. The additionally strengthened nonwoven may then be further processed such as by lamination or the like to further increase its utility.
摘要翻译：通过形成可卷曲的例如并排或偏心的护套/芯（A / B）的基本上连续的，纺粘的，卷边的双组分纤维来生产适合用于需要强织物层的各种应用的高蓬松低密度非织造织物，在收集之前未加热的配置。然后在不存在阻力的情况下将纤维加热和冷却，以获得Z方向上的最大卷曲，并且产生比通过加热方法拉伸其纤维的类似材料获得更高均匀性的蓬松材料的网。然后可以将所得非织造材料图案粘合或层压以获得额外的强度，而不会干扰所需的低密度非织造布。然后可以进一步加工另外加强的非织造材料，例如通过层压等来进一步提高其效用。

摘要： A method and apparatus for improved quenching of nonwoven filaments utilizing a turbulence inducing bar arrangement disposed in a stream of quenching gas between the quenching gas supply apparatus and the group of filaments being extruded. The bar arrangement increases the turbulence of the quenching gas so that the gas applied to the filament group has a turbulence intensity of at least about 5%. The turbulent quenching gas penetrates the interior of the filament bundle to provide more efficient removal of heat.
