摘要： A method for preparing stretchable bonded nonwoven fabrics which involves forming a substantially nonbonded nonwoven web of multiple-component continuous filaments or staple fibers which are capable of developing three-dimensional spiral crimp, activating the spiral crimp by heating substantially nonbonded web under free shrinkage conditions during which the nonwoven remains substantially nonbonded, followed by bonding the crimped nonwoven web using an array of discrete mechanical, chemical, or thermal bonds. Nonwoven fabrics prepared according to the method of the current invention have an improved combination of stretch-recovery properties, textile hand and drape compared to multiple-component nonwoven fabrics known in the art.
摘要翻译：一种制备可拉伸粘合非织造织物的方法，其包括形成能够显影三维螺旋卷曲的多组分连续长丝或短纤维的基本上非粘合的非织造纤维网，通过在自由收缩条件下加热基本上未粘合的纸幅来活化螺旋卷曲其中非织造材料基本上未粘合，然后使用离散的机械，化学或热粘合的阵列粘合卷曲的非织造纤维网。与本领域已知的多组分非织造织物相比，根据本发明的方法制备的非织造织物具有改进的拉伸恢复性能，纺织品手感和悬垂性的组合。

摘要： A spun yarn of cotton (35 wt %-80 wt %) and a bicomponent staple fiber (20wt%-65wt%) of poly(ethylene terephthalate) and poly(trimethylene terephthalate) based on total weight of the spun yarn. The spun yarn has a total boil-off shrinkage of about 22%. The bicomponent staple fiber component has a tow crimp development value of about 35%-70%; a tow crimp index value of about 14%-45%; a length of about 1.3-5.5 cm; and a linear density of about 0.7-3.0 decitex per fiber. The difference between the crimp index and the crimp development values is about 24%-35% absolute.

摘要： Included are bonded laminate constructions that have a modulus which approaches the sum of the modulus of the individual components of the laminate. By reducing variation in the modulus, the stretch or elasticity of the bonded or laminated fabric or garment is maximized. The bonded laminates include a bonding component that may be an elastomeric film, an adhesive, or a combination of a film with adhesive.

摘要： Upholstery stretch slipcovers are constructed from fabric having sufficient elastic recovery force so that the covers require no additional fabric to hold the slipcovers in place or to maintain a substantial absence of wrinkles in the slipcovers. The stretch slipcovers are particularly useful for chairs having separate back and seat cushions.
