An article of thermal protective clothing suitable for use in arc protection comprising a woven fabric comprising yarns comprising modacrylic fiber and aramid fiber, wherein 25 to 100 parts of the aramid fiber contain 0.5 to 20 weight percent discrete homogeneously dispersed carbon particles and 0 to 75 parts of the aramid fiber are free of discrete carbon particles; the fabric having an ATPV of 10 cal/cm.sup.2 or greater at a basis weight of 6 ounces per square yard (203 grams per square meter) or less, and a total content of 0.1 to 3 weight percent discrete carbon particles.

A polymer composition having antimicrobial properties, the composition comprising from 50 wt % to 99.99 wt % of a polymer, from 10 wppm to 900 wppm of zinc, less than 1000 wppm of phosphorus, and less than 10 wppm coupling agent and/or surfactant, wherein zinc is dispersed within the polymer; and wherein fibers formed from the polymer composition demonstrate a Klebsiella pneumonia log reduction greater than 0.90, as determined via ISO20743:2013 and/or an Escherichia coli log reduction greater than 1.5, as determined via ASTM E3160 (2018).

The present invention relates to a yarn and a yarn forming process, further relates to a protective textile produced by using the yarn and a knitting method therefor, and additionally relates to textile equipment for knitting the protective textile. The present invention discloses a yarn, wherein a core filament of the yarn uses a tungsten wire, which is covered at the center of an outer-layer yarn. A protective textile knitted by using the foregoing tungsten-wire yarn may be obtained by using single-yarn knitting, or by using double-yarn knitting by mixing another yarn. A single shuttle or two-shuttle knitting of the textile equipment may be used in the knitting method. Technical effects of the protective textile are that the protective textile knitted by using the tungsten wire as a core filament has a higher protection level, is lighter and thinner, better fit hand skin, and is operated more flexibly.

A hybrid tire cord has more uniform physical properties, and improved strength and fatigue resistance. The hybrid tire cord can easily be manufactured. The hybrid tire cord includes a nylon primarily twisted yarn and an aramid primarily twisted yarn, wherein the nylon primarily twisted yarn and the aramid primarily twisted yarn are secondarily twisted together, and after untwisting of the secondary twisting of the hybrid tire cord having a predetermined length, a length of the aramid primarily twisted yarn is 1.005 to 1.025 times a length of the nylon primarily twisted yarn.

A fabric for arc-protective garments includes first yarns and second yarns different from the first yarns. The first yarns include first modacrylic fibers, and the first modacrylic fibers contain an infrared absorber in an amount of 2.5 wt % or more with respect to a total weight of the first modacrylic fibers. The weight of the infrared absorber per unit area in the fabric for arc-protective garments is 0.05 oz/yd.sup.2 or more. An arc-protective garment includes the fabric for arc-protective garments.

The invention addresses the problem of providing a cloth and a protective product that have lightweight properties, wearing comfort, and further protection performance against electric arcs. A means for resolution is a cloth including a spun yarn containing a meta-type wholly aromatic polyamide fiber, wherein the cloth has a lightness index L-value of 25 or less.

The invention relates to a duplex cord for use as strength member in a belt bandage of a pneumatic vehicle tire, consisting of exactly two yarns that are twisted together at the ends, wherein the first yarn has a Z value of 600 mN/tex or more, and wherein the second yarn has a Z value of 75 mN/tex or less and a Y value of 150 mN/tex or less, where Z is the force normalized to the linear yarn density at which an elongation of 1% is obtained in the force-elongation diagram, where Y is the force normalized to the linear yarn density at which an elongation of 4% is obtained in the force-elongation diagram, and where the quotient X of the linear density of the first yarn divided by the linear density of the second yarn is in the range from 1.0 to 1.3.

The present disclosure relates to a method for manufacturing a hybrid tire cord that utilizes a difference in fineness using a general-purpose industrial filament such as nylon and polyester having high fineness of 200 denier or more relative to a fineness of an aramid filament.

A polymer-sheathed multi-filamentary strand for use in braided covers for wiring harnesses intended for use in challenging embodiments comprises a core of glass filaments wrapped in an aramid yarn, and sheathed in a siloxane-modified polyetherimide polymer. Shielding against electromagnetic interference may also be provided.

A pneumatic radial tire of the present technology has a belt reinforcing layer and a tread rubber. The belt reinforcing layer comprises a composite fiber cord having one aromatic polyamide fiber cord and one aliphatic polyamide fiber cord twisted therein. A total fineness of the composite fiber cords is from 1800 to 3200 dtex and an elongation under a load of 2.0 cN/dtex is from 3.0 to 4.0%. A rubber composition constituting the tread rubber is formed by compounding from 10 to 110 parts by weight of a silica having a nitrogen adsorption specific surface area of not less than 100 m.sup.2/g with 100 parts by weight of a diene rubber. A loss compliance of the rubber composition at 60 C. is not greater than 45 Pa.sup.1.
