The pretreatment liquid of the present invention is applicable for a fabric to be used for inkjet textile printing, and the pretreatment liquid contains a block copolymer including a hydrophobic block derived from a hydrophobic resin having an SP value of less than 11 and a hydrophilic block derived from a hydrophilic resin having an SP value of 11 or more, with the difference between the SP values of the hydrophobic resin and the hydrophilic resin of 1.0 or more; and water.

The present invention relates to a method of manufacturing a high tenacity yarn and a high tenacity yarn manufactured thereby. More particularly, the present invention relates to: a method of manufacturing a high tenacity yarn, the method including coating a yarn made of at least one of nylon and polyester to obtain a coated yarn, wherein the coating material contains 3 to 35 parts by weight of a reinforcing agent composed of a mineral material per 100 parts by weight of a coating liquid containing polyurethane; and a high tenacity yarn manufactured thereby. Therefore, it is possible to manufacture a yarn having high tenacity and improved processability by processing a nylon or polyester yarn having a relatively low tenacity as compared with a high modulus polyethylene (HMPE) yarn by use of a yarn coating technique, and further to reduce production cost.

A fabric comprising a cut-resistant polymeric coating including by weight 1 to 10 percent para-aramid particles, the particles having an average particle size of 20 to 500 microns.

Embodiments of the present disclosure generally relate to coated substrates having, e.g., anti-viral properties, to articles including the coated substrates, and to processes for making such coated substrates and articles. In an embodiment, a mask for preventing infection by a virus is provided. The mask includes a coated substrate having a breathing resistance (95 L/min, EN 149:2001) of about 6 mbar or less and a water droplet absorption time of less than about 5 seconds. The coated substrate includes a non-woven fabric having a weight of about 120 g/m.sup.2 or less according to ASTM D3776, and mineral oxide particles, iron oxide particles, or both, coupled to at least a portion of the non-woven fabric.

Nonwovens having low-density and resilience have a chemical formulation applied on one surface (e.g., a top surface) by any of various application methods. Then, the chemical formulation is forced to move toward the opposite surface of the nonwoven (e.g., move downward through the nonwoven from top to bottom). The chemical-treated nonwoven is dried to fix the chemical on the nonwovens. Movement through the nonwoven is performed in a controlled fashion so that after drying the distribution of a chemical formulation throughout the nonwoven (e.g., from the top surface to the bottom surface of a nonwoven) is controlled.

A water-repellent structure includes: a base material; and a water-repellent layer located on a surface of the base material. The water-repellent layer contains water-repellent particles and filler particles having an average particle size that is 20 times or more as large as an average particle size of the water-repellent particles.

A functional fabric is formed by bonding a polyester synthetic resin film mixed with carbon black fine particles to a fabric, in which the synthetic resin film is non-porous and has a thickness of 10 μm to 20 μm. The functional fabric is produced by producing a polyester synthetic resin film mixed with carbon black fine particles and bonding the synthetic resin film to a fabric, and the produced functional fabric is entirely or partially bonded to an inner wear or an intermediate clothes to produce clothing.

Embodiments of the present disclosure generally relate to coated substrates having, e.g., anti-viral properties, to articles including the coated substrates, and to processes for making such coated substrates and articles. In an embodiment, a coated substrate is provided. The coated substrate includes a substrate having a weight of about 120 g/m.sup.2 or less according to ASTM D3776, mineral oxide particles, iron oxide particles, or both, coupled to at least a portion of the substrate wherein the coated substrate has a breathing resistance (95 L/min, EN 149:2001) of about 6 mbar or less.

A fiber cord for reinforcement has an adhesive treatment agent attached to a surface thereof and includes, in an inner layer part thereof, two kinds of compounds each having a molecular weight of less than 1,000. The main compound is an aromatic compound or contains an -dicarboxylic acid component, and the other compound is an aliphatic compound or an alicyclic compound. It is preferable that the adhesive treatment agent is a resorcin-formalin-latex-based adhesive, that the fiber cord includes a twisted synthetic fiber, that the aromatic compound is a heterocyclic compound, that the main compound is located only in the inner layer part of the fiber cord, that a compound having a hexamethylene diisocyanate trimer structure is present, and that no latex is present in the inner layer part of the fiber cord. This fiber cord is produced through a two-stage treatment with a pre-treatment liquid and adhesive treatment liquid.

The method of the present invention for making a BNNT fabric comprises dispersing Boron-Nitride nanotubes at loading greater than 5 weight % in an electrospinning delivery solution; electrospinning the delivery solution onto a collector thereby forming a mat comprised of BNNT-PAN nano fibers; and, finally removing any electrospinning delivery solution from the mat leaving a fabric of intertwined Boron-Nitride nanotubes.
