Abstract: There is described a foam article comprising: a base foam having a textured surface; a trim cover covering at least a portion of the textured surface, the trim cover comprising: (i) a fmished outer layer comprising an occupant-contact outer portion and inner portion; (ii) a compressible buffer layer secured with respect to the inner portion of the finished outer layer; and (iii) a contact layer secured with respect to the compressible layer and configured to be in contact with the textured surface of the base foam, the contact layer having a secant modulus at 5% strain of at least about 7 when measured according to modified ASTM D3574-11, Test E, Tensile Test. There is also described a foam article comprising: a base foam having a textured surface; a trim cover comprising a finished outer layer; and optionally, a contact layer interposed between the foam element and the trim cover, the contact layer in contact with at least a portion of the textured surface of the base foam and comprising a contact material; the foam article having a read through score of at least 20 when measured pursuant to modified ASTM D3575-11 12 (Procedure B). The present inventors have discovered that the occurrence of “read through” may be obviated or mitigated if the contact layer having a secant modulus at 5% strain of at least about 7 when measured according to modified ASTM D3574-11, Test E, Tensile Test is used.

Abstract translation: 描述了泡沫制品，其包括：具有纹理表面的基底泡沫; 装饰盖覆盖纹理表面的至少一部分，装饰罩包括：（i）包含乘员接触外部和内部的外壳; （ii）相对于完成的外层的内部固定的可压缩缓冲层; 和（iii）相对于可压缩层固定并且构造成与基底泡沫的纹理化表面接触的接触层，接触层根据经修改的测量值在5％应变下具有至少约7％的割线模量 ASTM D3574-11，试验E，拉伸试验。 还描述了泡沫制品，其包括：具有纹理表面的基底泡沫; 装饰罩，其包括完成的外层; 并且可选地，介于泡沫元件和装饰罩之间的接触层，接触层与基底泡沫的纹理化表面的至少一部分接触并且包括接触材料; 当根据改进的ASTM D3575-1112（方法B）测量时，泡沫制品具有至少20的读数评分。 本发明人已经发现，如果根据改进的ASTM D3574-11，试验E，拉伸试验测量的接触层在5％应变下具有至少约7的正割模量的接触层可以消除或减轻“读通”的发生 用来。
