    Abstract: Process for the production of a nonwoven fleece from continuous filaments of a spun and stretched polymer yarn, especially a yarn composed of continuous hollow tubular polyethylene terephthalate filaments, wherein the yarn having permanently crimped filaments with an individual denier of about 0.5 to 20 denier is subjected to a temporary elongation within the range or region of the stress-strain curve which produces an elastic strain but under a load of at least 0.1 grams/denier, the permanent extension or set of the filaments being less than 4 percent, and then releasing the tension on the yarn whereby the crimped structure of the filaments is reformed and the yarn spreads out laterally. The resulting product is useful as a filler material in pillows, quilts, jackets and the like.

    Abstract translation: 一种由纺丝拉伸的合成纤维形成聚合物的连续管状细丝组成的无纺布毛条制品，特别是由连续的中空管状聚对苯二甲酸乙二醇酯长丝组成的纱线，其中单独的永久卷曲的长丝具有约0.5至20旦尼尔的纱线尺寸， 压接弧数为50至120弧/ 10厘米。 其管状结构的中空体积为10〜30％。 最终期望的制品是在纱线已经在产生弹性应变的应力 - 应变曲线的范围或区域内经受暂时伸长之后通过卷绕或分层基本上由这些长丝组成的纱线而形成羊毛的制品 但是在至少0.1克/旦的负载下，长丝的永久延伸或组合小于4％，然后释放纱线上的张力，由此将长丝的卷曲结构重新形成并且纱线横向扩展。 所得到的卷绕或分层纱线产品可用作枕头，被子，夹克等中的羊毛状填充材料。

    Abstract: A vertical drainage system for a basement or other below grade foundation wall having a sealer coat on its outer surface, a filamentary web or sheet composed of a fiber-forming synthetic thermoplastic polymer, preferably in the form of rows of looped amorphous melt-spun and bonded filaments, being laid along the wall between its outer sealer coat and the adjacent earth, and pipe means or the like near the bottom or footing of the wall to drain off water percolating downwardly through the filamentary filter layer.

    Abstract: Elastic sheet for use as covering fabric consists of a plurality of interesting amorphorus threads produced from a molton mass of a synthetic polymer, the threads having a diameter of 0.1-1.5mm, and being placed in layers, and bonded together at the points of intersection. Specifically the sheet has a uniform structure and density, and all the surfaces are formed by projecting loops. The loops are disposed horizontally, or nearly horizontally on the lower face of the sheet to form a solid structure, while the density of the loop layers diminishes towards the upper face, the loops on the upper force of the sheet, may also be horizontal or nearly horizontal. The elastic sheet is produced by (a) extruding a molton mass of polyamide through orifices disposed at similar distances from each other, to form at least three staggered rows of the ends in the form of a hank, onto a coaling liquid, pref. water, the distance between the spinning die and the upper surface of the bath being 2-30cm. pref. 4-20cm. and (b) continuously withdrawing the formed sheet through the bath.
