Embodiments of the disclosure include elastomeric stretch fibers containing an anti-tack agent, methods of preparing the fiber, methods of using this fiber, articles including this fiber, and the like.

A water-absorbing resin composition including 100 parts by weight of water-absorbing resin particles and 0.01 to 1 part by weight of additive particles, wherein a percent by weight of the additive particles, (x [%]), based on 100% by weight of the water-absorbing resin particles in the composition, and weight ratio of free additive particles, (y), relative to the percent by weight, (x [%]), satisfy the following formula:
0.04(x).sup.0.1y0.2(x).sup.0.5.

A fixing tool is disclosed, which can help reduce a possibility that heat may be transferred to a user when a state is changed in a material of a member for fixing a predetermined site of a human body. The fixing tool has a deformation portion that is configured to be deformable, that at least partially covers an outer periphery of any site of a limb, a trunk, a neck, and a head, and that is deformed to align with the site through the deformation, and a heat insulating material that is disposed in a portion corresponding to at least the site on an outside surface of the deformation portion.

Cellulose cyanoacrylate is employed either to bond two surfaces or to duplicate the shape of a three-dimensional object. The method is carried out by applying a release material to the object to be duplicated, applying a sheet of cellulosic material formed of wood fibers onto the three dimensional object, then saturating the sheet of cellulosic material with a cyanoacrylate glue and permitting the saturated sheet to cure. The resulting product duplicates the shape of the object. Two surfaces may be bonded by placing a sheet of cellulosic material between the two surfaces and applying the cyanoacrylate glue to edges of the sheet until saturated and allowing it to cure. Paper toweling may favorably be employed as the cellulosic material. This material may also be employed in bone or tooth repair. A break or fracture in an article can be repaired by positioning a sheet of cellulosic material over the break, saturating it with cyanoacrylate glue, and holding the saturated sheet in place with a releasable film. Irritating fumes may be suppressed by covering the saturated cellulosic material with a release film.

A photocurable device injection system for creating in situ polymerization via light or free-radical to enable fractured bone fixation. The system comprises a photosensitive polymeric resin sensitive to light, temperature, oxygen, enzymes, or a combination thereof. The photosensitive polymeric resin may be configured to cure at room temperature or physiological temperature with a light source. The photosensitive polymeric resin may be configured to depolymerize with ultrasonication, sonication, or a combination thereof. The system further comprises an implantable 3-dimensional biocompatible pouch comprising an optical light guide. The system further comprises one or more micro-sized ultrasonication probes configured to contact a three-dimensional pouch by one or more openings. The one or more probes may be configured to enable polymer outflow.

The present technology relates to composites, apparatuses, systems, and methods that are based on a photocurable composite useful for stabilizing, supporting, or otherwise healing an injured limb. The photocurable composite includes a light-curable resin and a filler material, where the light-curable resin includes about 50 vol % to about 99 vol % (based on the volume of the light-curable resin) of an acrylate-functionalized oligomer, wherein the backbone of the oligomer comprises a polyurethane, a polyether, a polyester, or a combination of any two or more thereof; about 1 vol % to about 50 vol % of a radical-reactive diluent; about 0.001 vol % to about 2 vol % of a photoinitiator; and optionally about 0.05 to about 25 vol % of a surface cure protection agent.
