摘要:
The invention relates to a fibrous material for heat-sealable medical packaging comprising a nonwoven fibrous single-layer substrate or a paper impregnated to the core by at least one polyurethane, at least one tackifier and optionally at least one functional additive. It also relates to the process for manufacturing this fibrous material, to the sizing composition used in the manufacturing process and to the medical packaging comprising such a fibrous packaging material.

An adhesive tape having a carrier and an adhesive layer applied to at least one side of the carrier, wherein the carrier is a thread-stitched web nonwoven carrier produced from a preconsolidated base web of staple fibers. Mutually parallel threads are stitched into the base web to form the final thread-stitched web nonwoven carrier, wherein the ultimate tensile strength of the preconsolidated but not as yet overstitched base web is less than 2 N/cm. In embodiments, the ultimate tensile strength of the preconsolidated but not as yet overstitched base web is below 1 N/cm or below 0.5 N/cm.

A blanket in the form of a patchwork quilt and a method of creation is provided. The quilt comprises a plurality of patchwork squares that are cut from a variety of cloth pieces. A plurality of fabric strips is cut to form the border of the patchwork square, whereby each strip comprises a heat-activated, dual-sided adhesive. The outer edges of the plurality of fabric strips are then sewn around the perimeter of the patchwork square, while the inner edge remains unsecured to the square. A keepsake may be inserted within the inner perimeter of the border, thereafter a user may secure the keepsake within the border by applying a heat source to the border.

Temperature switchable adhesives formed by combining a pressure sensitive adhesive, which does not exhibit temperature switchable properties, with a crystallizable oil are described. These temperature switchable adhesives exhibit a sharp reduction in peel strength when the temperature is raised above the switching temperature. The adhesive properties of these adhesives may be readily tuned by adjusting the ratio of the elastomer, tackifier, and the crystallizable oil, and by choosing different crystallizable oils. The temperature switchable adhesives have use in medical, consumer, and industrial applications.

A flame retardant patch for repairing a tear or hole in clothing or gear includes a flame resistant fabric and a pressure sensitive adhesive bonded to the fabric by hot melt lamination. The pressure sensitive adhesive contains halogenated flame retardant compounds. A release paper covers the pressure sensitive adhesive and is removed to allow application of the flame retardant patch to the clothing or other item being repaired. The patch is attached by applying pressure to the top fabric surface of the patch for approximately 45 seconds using the convex surface of a spoon-like object.
摘要:
The present invention is generally directed to adhesive compositions comprising selected ratios of crystalline and amorphous polymers. In some versions of the invention, polymers capable of existing in different configurations (e.g., a polymer such as polypropylene which can exist in an atactic, syndiotactic. or isotactic configuration) is used to prepare adhesives of the present invention. As an example, a selected amount of isotactic polypropylene is blended with a selected amount of atactic polypropylene to prepare an adhesive composition having one or more performance properties (e.g., bond strength) that are superior to the performance properties of a conventional hot-melt adhesive.
摘要:
An emblem having a design for securing to an article by the application of at least one of heat and pressure comprises a base having a front surface and a rear surface, the base being comprised of a woven fabric. The emblem design is comprised of two portions, a first portion of the emblem design being woven into the fabric base when the fabric base is made and a second portion of the emblem design being embroidered into the fabric base. A layer of thermoplastic adhesive material is bonded to the rear surface of the fabric base for securing the emblem to the article.

摘要:
A vapor permeable, water impermeable film is coating partially with an adhesive surface coating. The partial adhesive coating is deposited on both surfaces of the film and coated areas on one surface of the film are at least partially in line with the coated areas of the second surface. A three ply laminate sheet is manufactured having a middle layer consisting of a vapor permeable water impermeable films having partial surface coating with an adhesive material on both surfaces.
