摘要:
Disclosed are multicomponent fibers derived from a blend of a sulfopolyester with a water non-dispersible polymer wherein the as-spun denier is less than about 6 and wherein the water dispersible sulfopolyester exhibits a melt viscosity of less than 12,000 poise measured at 240° C. at a strain rate of 1 rad/sec, and wherein the sulfopolyester comprising less than about 25 mole % of residues of at least one sulfomonomer, based on the total moles of diacid or diol residues. The multicomponent fiber is capable of being drawn at a relatively high fiber speed, particularly at least about 2000 m/min, and may be used to produce microdenier fibers. Fibrous articles may be produced from the multicomponent fibers and microdenier fibers. Also disclosed is a process for multicomponent fibers, nonwoven fabrics, and microdenier webs.

A fabric, in particular for a paper making machine, includes a plurality of helically wound coil members arranged side by side with respect to each other in an intermeshing manner, such that connecting channels are formed by adjacent intermeshing coil members, a hinge member being introduced into and extending along each connecting channel for interconnecting adjacent coil members, a stuffer channel being formed within each coil member extending along and between two connecting channels associated to a respective coil member, at least a part of the stuffer channels being filled with stuffer members extending longitudinally within the stuffer channels, a stuffer material being provided at least in regions of the fabric for filling spaces formed within the fabric between the coil members, the hinge members and the stuffer members.
摘要:
A biocompatible material may be configured into any number of implantable medical devices including a vascular closure device. The vascular closure device includes a fibrous structure formed from at least one randomly oriented fiber, the randomly oriented fiber comprising at least one polymer, and at least one agent, in therapeutic dosage, incorporated into at least one of the fibrous structure and the at least one randomly oriented fiber.
摘要:
An electrically conductive elastic composite yarn comprises an elastic member that is surrounded by at least one conductive covering filament(s). The elastic member has a predetermined relaxed unit length L and a predetermined drafted length of (N×L), where N is a number preferably in the range from about 1.0 to about 8.0. The conductive covering filament has a length that is greater than the drafted length of the elastic member such that substantially all of an elongating stress imposed on the composite yarn is carried by the elastic member. The elastic composite yarn may further include an optional stress-bearing member surrounding the elastic member and the conductive covering filament. The length of the stress-bearing member is less than the length of the conductive covering filament and greater than, or equal to, the drafted length (N×L) of the elastic member, such that a portion of the elongating stress imposed on the composite yarn is carried by the stress-bearing member.
摘要:
A polyester combined-filament yarn having an excellent stretch property and a bathochromic effect, as well as uniformity of apparent dyed color density, comprises two different multifilament components (A) and (B), wherein the multifilament component (A) comprises polyester filaments composed of polyethylene terephthalate (PET) polymer, a metal-containing phosphorus compound (a) and an alkaline earth metal compound (b), and a conjugate multifilament component (B) comprises side-by-side or eccentric core-sheath conjugate polyester filaments composed of two mutually different polyester resins (at least one of which is polytrimethylene terephthalate resin), the mass ratio (A)/(B) of components (A) and (B) is in the range of 80/20 to 50/50. Woven or knitted fabrics comprising the combined-filament yarn are useful for women's and men's fashion apparel and black formals.
摘要:
A woven panel is formed from a plurality of elongated yarn with an essential core and a superficial core. The essential core yarns provide mechanical strength for the woven material in supporting the superficial core yarns when used in load bearing articles such as the seat or back portions of an article of furniture.
