Medical device and method for the production thereof
A medical device in the form of a nonwoven wound dressing includes rotospun fibers including at least one synthetic and bioabsorbable polymer and at least one hydrophilic and/or tissue-adhesive polymer, and a method of producing the medical device including using rotospinning to produce fibers from a fiber raw material including at least one synthetic and bioabsorbable polymer and at least one hydrophilic and/or tissue-adhesive polymer.
Absorbent materials
The present invention provides dry-creped absorbent material comprised of gelling fibres intended for use particularly, but not necessarily exclusively, as wound dressings or as a component (absorbent substrate) of a wound dressing, as well as wound dressings comprising the absorbent material.
ONE-STEP FORMED GEL FIBER COMPOSITE SCAFFOLD MATERIAL AND PREPARATION METHOD AND USE THEREOF
A one-step formed gel fiber composite scaffold material can be prepared by preparing an electrospun film through a high-voltage electrostatic method and soaking the electrospun film into a phase separation solution to obtain the gel fiber composite scaffold material. The obtained composite scaffold material is an extracellular matrix simulated composite material and can be modified by adding multiple natural biomaterials, so that the composite material is closer to an extracellular matrix in terms of components
Meltblown nonwoven fabrics, and composites thereof
A meltblown nonwoven formed from a bicomponent fiber, wherein: the bicomponent fiber has a first region and a second region, the first region is formed from a first composition comprising at least 75 wt. % of a polypropylene; the second region is formed from a second composition comprising at least 75 wt. % of an ethylene/alpha-olefin interpolymer.
Absorbent layer for an absorbent article
A fluid management layer having an integrated, carded, nonwoven is described. The fluid management layer has a basis weight of between about 115 grams per square meter (gsm) and about 200 gsm; a plurality of absorbent fibers; a plurality of stiffening fibers; and a plurality of resilient fibers. The absorbent fibers make up from about 20 percent to about 60 percent by weight of the fluid management layer. The stiffening fibers have a dtex of between 4 and 10, and the resilient fibers have a dtex of between 3 and 12.
Loop element of hook/loop fastener and method of making same
A hook-and-loop fastener has a hook element comprising a substrate having a face from which projects a multiplicity of hooks and a loop element formed by of a fiber web. The fiber web is formed by a homogenous mixture of first multicomponent filaments each formed by a high-melting-point polymer and a low-melting-point polyolefinic polymer and second polyolefinic monocomponent filaments. The first filaments constitute between 20% and 80% by weight of the mixture. The fiber web has a face formed with a patterned array of dense bonded regions of a predetermined small thickness interspersed with less dense open regions of a predetermined big thickness substantially greater than the small thickness of the small thickness interspersed with less dense open regions of a predetermined big thickness substantially greater than the small thickness of the bonded regions so that the filaments of the open regions form loops.
MULTILAYERED NONWOVEN FABRICS AND METHOD OF MAKING THE SAME
A nonwoven composite fabric including a first nonwoven layer composed substantially of meltblown fibers, the fibers within the first nonwoven layer having diameters that vary in accordance with a first distribution, a second nonwoven layer composed substantially of meltblown fibers, the fibers within the second nonwoven layer having diameters that vary in accordance with a second distribution, and a third nonwoven layer composed substantially of meltblown fibers, the third nonwoven layer disposed between the first and second nonwoven layers, the fibers within the third nonwoven layer having diameters that vary in accordance with a third distribution that is greater than the first and second distributions.
DURABLE PILLING RESISTANT NONWOVEN INSULATION
Provided is batting that includes a bonded nonwoven web made from a fiber mixture containing: (a) 20 to 55 wt % of siliconized fibers having a denier of 1.5 to 10.0 and a length of 51 mm to 84 mm; (b) 10 to 45 wt % of hollow conjugate fibers having a spiral crimp, and having a denier of 1.5 to 10.0 and a length of 51 to 84 mm; (c) 10 to 45 wt % of a first population of binder fibers which are elastomeric co-polyester binder fibers having a denier of 1.5 to 8.0, a length of 51 mm to 84 mm, and a bonding temperature of 110? C. to 180? C.; and (d) 1 to 20 wt % of a second population of binder fibers, which have a denier of 1.5 to 6.0, a length of 51 mm to 84 mm, and a bonding temperature of 80? C. to 135? C.
COMPOSITE NONWOVEN SHEET MATERIAL
A composite nonwoven sheet material includes pulp fibers, a reinforcement material and microfibers. The sheet material has one pulp-enriched first outer layer and one microfiber-enriched second outer layer, the reinforcement material is thereby interposed between the pulp-enriched first outer layer and the microfiber-enriched second outer layer and the pulp fibers and the microfibers penetrate the reinforcement material. Also disclosed is a process of producing such composite nonwoven sheet material and the use of such composite nonwoven sheet material.
ABSORBENT LAYER FOR AN ABSORBENT ARTICLE
