    Abstract: The invention relates to a system for fastening refastenable garment such as diaper or incontinent garment in which a tape and polymer backing material for the garment are provided such that tape may be removed after refastening to the diaper without tearing of the polymer material. The system of the invention utilizes a polypropylene tape material that is embossed on the outer surface and smooth on the adhesive-carrying surface. The adhesive on the tape is a semihard adhesive that provides high adhesion values to the polymer that nevertheless may be peeled free for removal of the tape and subsequent refastening. The polymer forming the outer backing if the diaper is a relatively thick, embossed polymer sheet. In the refastenable system of the invention the strength and adherence of the tape to the strong, embossed polymer backing sheet is controlled so as to achieve secure fastening with release of the adhesive from the embossed sheet without tearing.

    Abstract translation: 本发明涉及一种用于紧固可重复扣紧的衣服的系统，例如尿布或失禁服装，其中提供用于衣服的带和聚合物背衬材料，使得可以在对尿布进行再补充之后去除带而不撕裂聚合物材料。 本发明的系统利用在外表面上压花并在粘合剂承载表面上光滑的聚丙烯带材料。 胶带上的粘合剂是半硬化粘合剂，其为聚合物提供高粘合力值，然而可以将其剥离以除去胶带并随后进行再吸塑。 如果尿布是相对厚的压花聚合物片，则形成外衬垫的聚合物。 在本发明的可重新扣紧系统中，控制带到强压花聚合物背衬片的强度和粘附性，以便在没有撕裂的情况下从压花片释放粘合剂来实现牢固的紧固。

    Abstract: In the commercial production of tissue paper and the like a web, formed from a slurry of water and fiber, is creped while essentially (98%) dry, from a rotating cylindrical dryer. Adhesives are frequently employed to hold the web to the dryer surface and polyvinyl acetate-ethylene copolymer emulsions serve this function. Such adhesives are relatively soft, tend to adhere to the fabrics which carry the paper web to the dryer surface and tend to make cleaning of the carrying fabric difficult. Additionally, these adhesives tend to cause blocking of the tissue paper when in roll form and adjacent plies of the paper tend to be torn upon separation. However, it has been found that by providing an adhesive creping composition to have between about 10% to 33% by weight of a water soluble polyvinyl alcohol, based on polyvinyl acetate-ethylene copolymer solids present in the composition, the cleanability of the carrying fabric is improved, roll blocking is minimized and the consistency of the adhesion of the drying web to the dryer is improved. Additionally, the tendency of the polyvinyl alcohol which itself has adhesive properties, to foul the dryer with a hard uneven film of alcohol is overcome.
