Methods of assembling apparel products having cyclodextrin-azobenzene adhesives
Embodiments provide methods of assembling an apparel product. The methods include applying a composition to a portion of a major component of the apparel product or a portion of a minor component of the apparel product. The methods include coupling the portion of the minor component with the portion of the major component via the composition. The major component forms a base portion of the apparel product and is configured to be supported and worn at least partially over a portion of a wearer. The minor component forms a secondary portion that is configured to be coupled to the major component with an adhesive. The composition is cured to form the adhesive and the apparel product. The adhesive includes a polymer having a cyclodextrin moiety bonded to an azobenzene moiety.
Starch and carboxylic acid binder compositions and articles made therewith
Fiber-containing composites are described that include woven or non-woven fibers, and a binder that holds the fibers together. The binder may include the reaction product of a starch and a polycarboxylic acid. The starch has a weight average molecular weight that ranges from 1×10.sup.6 Daltons to 1×10.sup.7 Daltons. The fiber-containing composite has an unaged tensile strength of greater than 4.0 and an aged tensile strength greater than 3.0. Also described are methods of making the fiber-containing composites. The methods may include applying a binder composition to fibers to form coated fibers, measuring a moisture content of the coated fibers, and curing the coated fibers in a curing oven to form the fiber-containing composite. The binder composition may include a starch having a weight average molecular weight that ranges from 1×10.sup.6 Daltons to 1×10.sup.7 Daltons, and a polycarboxylic acid.
SYSTEM FOR WRAPPING ELONGATED OBJECT
A support tape extends longitudinally along an elongated object, is wrapped around the object, and has a pair of opposite longitudinal edges, an inner face engaging the object, and an outer face turned outward away from the object. The support tape is of single-layer design and having a class D abrasion resistance according to LV 312-1. One closure strip of an adhesive compound extends along one of the faces at one of the edges, and another closure strip of an adhesive compound extends parallel to the edges, along the other face, and transversely offset on the other face from the one closure strip. It is adhered to the one closure strip. A fixing strip of an adhesive compound extends longitudinally on the inner face, offset thereon from the one and other closure strips, and adheres the tape to the object.
STARCH AND CARBOXYLIC ACID BINDER COMPOSITIONS AND ARTICLES MADE THEREWITH
Fiber-containing composites are described that include woven or non-woven fibers, and a binder that holds the fibers together. The binder may include the reaction product of a starch and a polycarboxylic acid. The starch has a weight average molecular weight that ranges from 1×10.sup.6 Daltons to 10×10.sup.6 Daltons. The fiber-containing composite has an unaged tensile strength of greater than 4.0 and an aged tensile strength greater than 3.0. Also described are methods of making the fiber-containing composites. The methods may include applying a binder composition to fibers to form coated fibers, measuring a moisture content of the coated fibers, and curing the coated fibers in a curing oven to form the fiber-containing composite.

A laminate comprises a wicking fabric and a polymeric film adhered to both sides of the wicking fabric, wherein the wicking fabric comprises a plurality of holes, the polymeric films on both sides of the wicking fabric are fused together at each hole, and the laminate functions as an air barrier when measured in accordance with ASTM E2178-13, and allows the passage of liquid water as per ASTM E2273-18.
LOW TACK HOT-MELT PRESSURE SENSITIVE ADHESIVES
The invention relates to a hot-melt pressure sensitive adhesive composition comprising at least one styrenic block copolymer, at least one tackifying resin, at least one mineral oil and from 4 to 15% by weight of at least one wax selected from the group consisting of paraffin waxes, Fischer-Tropsch waxes, ethylene-vinyl acetate waxes and any mixture thereof, based on the total weight of the hot-melt pressure sensitive adhesive composition. The invention also relates to an article comprising a surface coated with such a hot-melt pressure sensitive adhesive composition, to a use of such a hot-melt pressure sensitive adhesive composition and to a process for preparing such a hot-melt pressure sensitive adhesive composition.
Moisture-curable adhesive tape and method for jacketing elongated items, especially leads
The present invention relates to an adhesive tape and to a method for jacketing an elongated item, more particularly cable sets. The adhesive tape must cure within the operational dictates for further processing, e.g. within 6 min, and after curing must exhibit the required dimensional stability properties. However, the adhesive compositions must not cure during storage itself, since otherwise they can no longer be used. Nor may the curing temperatures be too high, since otherwise the lead insulation, which is often made of PVC, may suffer damage. The invention proposes a method for jacketing an elongated item such as more particularly leads or cable sets, where a tape which comprises a moisture-curing binder on a carrier is first impregnated with water and immediately thereafter is guided in a helical line around the elongated item or the elongated item is wrapped in an axial direction by the adhesive tape, the elongated item together with the adhesive tape wrapping is brought into the desired disposition, more particularly into the cable set plan, the elongated item is held in this disposition, while the curable adhesive cures. Alternatively proposed is a method for jacketing an elongated item such as more particularly leads or cable sets, where a tape which comprises a moisture-curing binder on a carrier is guided in a helical line around the elongated item or the elongated item is wrapped in an axial direction by the adhesive tape, the elongated item together with the adhesive tape wrapping is brought into the desired disposition, more particularly into the cable set plan, the elongated item is held in this disposition, and the curable adhesive is brought to cure by the supply of moisture.
