Abstract
A sewing thread comprising at least one precursor material of a product at its outer surface, which imparts a stitched connection produced with such a thread an increased adherence to the material to be sewn. Furthermore, the invention provides a sewing thread wherein the applied precursor material transforms to form a product which is capable of enlarging the outer diameter of the sewing thread, particularly in an aqueous environment. Furthermore, the invention provides a method for producing waterproof stitched connections.
Claims24
A sewing thread comprising:
- a thread, and
- a precursor material impregnated at least partway into said thread, said sewing thread capable of being sewn into a material, said precursor material capable of being activated and converting after its activation to a product which imparts an increased adherence between the sewing thread and the stitched material in the stitched connection produced with such a thread and which increases the outer diameter of the sewing thread by activating a property of the precursor material which increases the actual or apparent volume, said activation excluding a foaming process, and wherein said precursor material is selected from the group consisting of:
- polysaccharides,
- acrylamides, silicone resins, and starches,
- polytetrafluoroethylene mixed with an, an expandable material, and
- inorganic expandable materials, and mixtures thereof.

A sewing thread comprising:
- a thread, and
- a precursor material impregnated at least partway into said thread, said sewing thread capable of being sewn into a material, said precursor material capable of being activated and converting after its activation to a product which imparts an increased adherence between the sewing thread and the stitched material in the stitched connection produced with such a thread and which increases the outer diameter of the sewing thread by activating a property of the precursor material which increases the actual or apparent volume, said activation excluding a foaming process, and wherein said precursor material is formed of molecules capable of causing change of volume due to conformational changes and selected from the group consisting of natural hetropolymers, synthetic hetropolymers, natural homopolymers and synthetic homopolymers.
A sewing thread comprising:
- a thread, and
- a precursor material impregnated at least partway into said thread, said sewing thread capable of being sewn into a material, said precursor material capable of being activated and converting after its activation to a product which imparts an increased adherence between the sewing thread and the stitched material in the stitched connection produced with such a thread and the stitched material in the stitched connection produced with such a thread and which increases the outer diameter of the sewing thread by activating a property of the precursor material which increases the actual or apparent volume, said activation excluding a foaming process, wherein said precursor material is selected from the group consisting of:
- copolymers of vinyl chloride and vinyl acetate.
A sewing thread comprising:
- a thread, and
- an acrylamide precursor impregnated at least partway into said thread, said sewing thread capable of being sewn into a material, said precursor material capable of being activated and converting after its activation to a product which imparts an increased adherence between the sewing thread and the stitched material in the stitched connection produced with such a thread and excluding a foaming process, wherein said thread contains additives selected from the group consisting of methylene bisacrylamide, N,N,N',N'-tetramethyl ethylene diamine, and N,N,N',N'-tetramethyl ethylene diamine.
