摘要： A specific class of water-borne, water redispersible laminating adhesives is disclosed which is desirable for bonding nonwoven substrates to themselves or to other substrates. The adhesives provide improved bond strength and improved water redispersibility when compared to laminating adhesives currently used for the same purpose. Furthermore, the novel adhesives are much less sensitive to the presence of significant levels of plasticizer than are laminating adhesives currently used, which exhibit reduced water redispersibility when such plasticizers are present in significant amounts. The novel laminating adhesives contain an aqueous styrene/acrylic polymer dispersion prepared by radical-initiated emulsion polymerization of unsaturated monomers in the presence of starch degradation products having a weight average molecular weight range of from about 2500 to 25000 and which are obtainable by hydrolysis in the aqueous phase. The adhesives may contain only the starch-modified, styrene/acrylic polymer dispersion, or may further include other components, such as plasticizers and/or rheology modifiers, when required. The novel adhesives are particularly useful in disposable articles wherein a nonwoven substrate is bonded to a second substrate via a water-borne, laminating adhesive. The disposable articles may include an absorbent core portion disposed between and proximate the nonwoven and second substrate.

摘要翻译：公开了一种特定类型的水性，水可再分散层压粘合剂，其将非织造基材粘合到其自身或其它基材上是理想的。与目前用于相同目的的层压粘合剂相比，粘合剂提供改善的粘结强度和改善的水再分散性。此外，与当前使用的层压粘合剂相比，新型粘合剂对于显着水平的增塑剂的存在不那么敏感，当这种增塑剂以显着量存在时，其表现出降低的水再分散性。新型层压粘合剂含有通过在具有约2500至25000的重均分子量范围的淀粉降解产物存在下由不饱和单体的自由基引发的乳液聚合制备的水性苯乙烯/丙烯酸聚合物分散体，其可通过在水相。当需要时，粘合剂可以仅含有淀粉改性的苯乙烯/丙烯酸聚合物分散体，或者可以进一步包括其它组分，例如增塑剂和/或流变改性剂。新型粘合剂在一次性制品中特别有用，其中非织造基底通过水性层压粘合剂结合到第二基底。一次性物品可以包括设置在非织造材料和第二基底之间和附近的吸收芯部分。

摘要： Thermally-inhibited starches and flours are used in conventional water-based adhesives such as corrugating, cigarette, remoistenable, kraft adhesives. The starches or flours are thermally-inhibited by dehydrating the starch to anhydrous or substantially anhydrous and then heat-treating the starch or flour for a time and at a temperature sufficient to inhibit the starch and improve its viscosity stability. The starch or flour may be thermally or non-thermally dehydrated (e.g., by alcohol extraction or freeze-drying). Preferably, the pH of the starch is adjusted to at least a neutral pH prior to the dehydration.

摘要： The present invention is directed to remoistenable and non-remoistenable adhesives which contain at least about 50 wt % of a maltodextrin syrup having a reducing sugar content of about 5-19 dextrose equivalent and solids content of about 60-80 % water, and an effective amount of other conventional adhesive additives. When the adhesive is a remoistenable adhesive, a chemically derivatized starch having an amylose content of 40 % or less and a D.S. of about 0.01 to less than about 0.50 is used. A preferred remoistenable adhesive also contains polyvinyl acetate and/or ethylene vinyl acetate in an amount from about 15-90 wt. % The maltodextrin syrup is prepared from a converted or a non-converted, chemically derivatized or underivatized granular starch, by a high solids, single phase enzyme conversion process. When derivatized, the maltodextrin has (i) substituents in an amount sufficient to provide a degree of substitution between greater than about 0.01 and less than about 0.50. Some of the chemically-derivatized maltodextrins have a polymodal molecular weight distribution with one peak between about 630-1600 daltons and at least one other peak between about 1600-2,500,000 daltons.
