Abstract:
A method for manufacturing an implantable film and a prosthesis comprising such a film The present invention relates to a method for manufacturing a non porous film intended to be implanted in the human body, said method comprising the following steps: preparation of a first film, called intermediate film, via gelling of a starting solution comprising at least one polymer selected in the group consisting of collagen, glycosaminoglycans, and mixtures thereof, immersion of said intermediate film in an alkaline composition comprising at least one C1-C4 alcohol, drying of the film obtained at the end of the immersing step. The invention also relates to a method for manufacturing a prosthesis comprising a textile support and such a film.

Abstract:
In one aspect, parachute buffer materials are described herein. In some embodiments, parachute buffer materials described herein comprise a fabric formed from a plurality of fibers and a coating disposed on at least one outer surface of the fabric. The fibers have an inner component formed from a thermoplastic material and an outer component formed from a non-thermoplastic material. In some cases, the fabric is a woven fabric. Additionally, the coating can comprise or contain a silicone along with, or without, other functional components. Moreover, materials described herein can be used to form various structures for parachute buffering applications, and the coatings of materials described herein can enhance the materials' buffering performance.
Abstract:
A stretchable coated fabric is treated for water repellency with a fluorinated water repellent that comprises a copolymer containing a perfluoroalkyl group with six or less carbon atoms (C6 fluorinated water repellent). The use of no C8 fluorinated water repellents that contain perfluorooctanoic acid, perfluorooctane sulfonate, and the like makes the fabric exerts no influence on the environment. And the fluorinated water repellent has a toluene repellency of 100 seconds or longer; a synthetic resin solution applied to at least one side of the stretchable fiber fabric has a thixotropic index at 23° C. in a range from 1.4 to 2.0; and the synthetic resin has a 100% modulus of 5 kgf/cm2 or greater. This prevents the synthetic resin from leaking to the back side and allows formation of a resin coating film that has good film forming properties.

Abstract:
A lightweight carpet product includes a greige carpet having a primary backing and tufted fibers, a secondary backing including a nonwoven textile of synthetic fibers, and a thermoplastic adhesive composition adhered to the greige carpet and the secondary backing. The thermoplastic adhesive composition includes a modified polyethylene terephthalate (PET) having a crystallinity less than unmodified PET and a melting point from about 90° C. to about 150° C., and a particulate filler. Methods of manufacture include using a thermoplastic adhesive composition to adhere a greige carpet to a secondary backing to form a lightweight carpet product.
Abstract:
Embodiments of the present invention relate to a tufted carpet. The carpet may include a pile layer having a bulked continuous filament (BCF) yarn. The BCF yarn may include a polypropylene (PP) yarn with a tenacity between about 2.6 cN/dtex and about 3.2 cN/dtex at an elongation of about 50% to about 70%. Alternatively, the BCF yarn may include a polyethylene terephthalate (PET) with a tenacity between about 2.6 cN/dtex to about 3.4 cN/dtex at an elongation of about 20% to about 40%.
Abstract:
Substantially flame retardant-free carpets comprising poly(trimethylene terephthalate) yarn having minimal carrier and, optionally, minimal antistatic agent, are disclosed, as are methods for making such carpets.
Abstract:
The invention is intended to provide a simple and economical method for producing a ductile tufted product, particularly a tufted upper carpet layer that is particularly ductile, in particular for the automotive interior area. For this purpose, a melt-blown non-woven fabric is placed on a ductile polyester tufted backing and the melt-blown non-woven fabric and the polyester tufted backing are tufted together.
Abstract:
Reactive geocomposite mats, and their method of manufacture, for treating contaminants in soil or water that allow the passage of essentially non-contaminated water therethrough. The geocomposite mat includes a pre-formed woven or non-woven geotextile, having a thickness of about 6 mm to about 200 mm, and having, a porosity sufficient to receive a powdered or granular contaminant-reactive material, contaminant-sorptive material, or a contaminant-neutralizing material (hereinafter collectively referred to as “contaminant-reactant material” or “contaminant-reactive material”) throughout its thickness, or in any portion of the thickness across its entire major surface(s). The powdered or granular contaminant-reactive material is disposed within the pores of the previously formed, high loft geotextile mat to surround the fibers, e.g., by vacuum or vibrating the high loft mat while in contact with the contaminant-reactive material to allow the powdered or granular contaminant-reactive material to flow by gravity into the pores of the previously formed geotextile and vibrational forces. Liquid-permeable cover sheets are adhered to the upper and lower major surfaces of the filled geotextile to prevent the powdered or granular material from escaping from the geotextile during transportation and installation.
Abstract:
To improve the liquid barrier properties of a carpet, a repellency compound, such as a fluorochemical, is applied to the backstitch side or underside of the primary backing layer of a carpet.
