摘要： Disclosed herein are nonwoven fabric composites comprising layers of spunbond and meltblown nonwoven webs. Such composites are prepared by forming or assembling the layers of the composite such that there is at least one outer layer of spunbond fibers disposed on at least one inner meltblown layer. The at least one outer layer comprises substantially parallel stripes of spunbond, continuous filament fibers with at least two different types of stripes being used. The stripes of fibers within the spunbond layer(s) are also predominately oriented in the machine direction of the nonwoven fabric composite. All layers of the fabric composites herein are bonded together via thermal, adhesive, ultra-sonic or mechanical bonding means. Such composites can be fashioned to vary the ratio of cross direction stretch to machine direction stretch.

摘要： The invention relates to the field of production of lactams from aminonitriles, and in particular to the production of ε-caprolactam by the vapor phase hydrolytic cyclization of 6-aminocapronitrile. A crude liquid caprolactam comprising ε-caprolactarn (CL), 6-aminocapronitrile (ACN) and water obtained from a vapor phase cyclization reaction of ACN is contacted with hydrogen in the presence of a hydrogenation catalyst to convert the ACN in the crude liquid caprolactam to a product comprising hexamethylenediamine (HMD) and hexamethyleneimine (HMI). Tetrahydroazepine (THA) in the crude liquid caprolactam is converted to HMI during this hydrogenation. The HMD and HMI have lower boiling points compared to ACN and thus they are more easily separated from CL in the subsequent distillation operations. Thus a process to make CL from ACN with fewer distillation stages, and with lower pressure drop and lower base temperature, is accomplished.
摘要翻译：本发明涉及由氨基腈生产内酰胺的领域，特别涉及通过6-氨基己腈的气相水解环化生产ε-己内酰胺。包含ε-己内酯（CL），6-氨基己腈（ACN）和由ACN的气相环化反应获得的水的粗液体己内酰胺在氢化催化剂存在下与氢气接触，将粗液体己内酰胺中的ACN转化为包含六亚甲基二胺（HMD）和六亚甲基亚胺（HMI）的产品。粗制液体己内酰胺中的四氢吖庚因（THA）在该氢化期间转化为HMI。与ACN相比，HMD和HMI具有较低的沸点，因此在随后的蒸馏操作中它们更容易与CL分离。因此，实现了具有较少蒸馏阶段以及较低压降和较低基础温度的来自ACN的CL的方法。

摘要： The invention relates to the field of separation by distillation of 6-aminocapronitrile (ACN) and hexamethylenediamine (HMD) from a mixture comprising ACN, HMD, tetrahydroazepine (THA), adiponitrile (ADN) and low boilers (LB). Also disclosed is a method for producing a distillate stream comprising HMD; a side draw stream comprising ACN, THA and low levels of dimers of ACN and HMD; and a tails stream comprising ACN, THA and substantially higher levels of dimers of ACN and HMD than found in the side draw stream. The side draw stream is particularly suitable for use in the production of caprolactam since the low levels of dimers of ACN and HMD do not greatly affect the catalyst life in the caprolactam production process. The tails stream can be further distilled to produce a tails distillate stream comprising ACN and THA, which can be recycled back to the first distillation column, further increasing recovery of ACN from the feed stream. Process conditions of the method of the invention disfavor the production of 2-cyanocyclopentylideneimine (CPI).
摘要翻译：本发明涉及从包含ACN，HMD，四氮氮平（THA），己二腈（ADN）和低锅炉（LB））的混合物中蒸馏出6-氨基己腈（ACN）和六亚甲基二胺（HMD）的分离领域。还公开了一种生产包含HMD的馏出液流的方法; 包含ACN，THA和ACN和HMD的低水平二聚体的侧引流; 以及包含ACN，THA和比侧馏分流中发现的ACN和HMD的显着更高水平的二聚体的尾料流。由于ACN和HMD的低水平二聚体不会极大地影响己内酰胺生产过程中的催化剂寿命，所以侧引流特别适用于生产己内酰胺。可以进一步蒸馏尾巴料流以产生包含ACN和THA的尾馏馏料流，其可再循环回第一蒸馏塔，进一步增加ACN从进料流中的回收。本发明方法的工艺条件不利于2-氰基环戊烯亚胺（CPI）的生产。
