摘要:
A variety of agricultural spacer fabrics/textiles are provided that protect plants from insect penetration while allowing for light and air penetration, and methods of use. The textiles can be used alone or in conjunction with agents such as insecticides, insect repellants, and fungicides. The agricultural textile can have an outermost fabric layer, an innermost fabric layer, and a plurality of filaments connecting the outermost fabric layer and the innermost fabric layer.

A sponge-like polymeric adsorption material prepare by a process including: preparing a linear polymer yarn from a linear polymer via melt-blow spinning, treating the linear polymer yarn with a crosslinking agent and a porogen agent; heating the treated linear polymer yarn at 130 to 150° C. for 25 to 35 seconds to obtain a fibrous polymeric adsorption material; and weaving the fibrous polymeric adsorption material to obtain the sponge-like polymeric adsorption material. The linear polymer has a molecular weight of 15,000 to 20,000 g/mol. The fibrous polymeric adsorption material includes fibers with a diameter of 4 to 6 microns. The crosslinking agent is in an amount of 1 to 3 weight % of the linear polymer. The crosslinking agent is a diacrylate ester compound having Formula J1, J2 or J3. The porogen agent is in an amount of about 1 weight % of the linear polymer. The sponge-like polymeric adsorption material has a thickness of 15-20 mm and a density of 600-720 g/L. The linear polymer has a molecular weight of 15,000 to 20,000 g/mol.

摘要:
Lubrication of wool fibers for combed wool sliver production, via contacting of the wool fibers with a lubrication composition including a mixture of C6-22 fatty acid methyl esters based on fatty acids selected from the group consisting of coconut fatty acids, palm kernel fatty acids, palm oil fatty acids, and mixtures thereof, is disclosed.
摘要:
The present invention is a method for producing carbon fiber, characterized by using a carbon-fiber precursor produced from a polymer having a narrow molecular weight distribution and by applying only a small amount of a smoothing agent, composed of a specific component, to the carbon fiber surface immediately before winding of carbon fiber. According to the present invention, it is possible to stably produce carbon fiber, which has excellent dispersibility and do not deteriorate in quality and quality even when a sizing agent is not attached to the carbon fiber surface. In addition, the produced carbon fiber is suitable for use in a composite material which is produced by high-temperature processing using a thermoplastic resin.

A synthetic fiber finish includes a lubricant (A), a polyhydric alcohol fatty acid ester having at least one hydroxyl group per molecule (B), and an organic sulfonic acid compound (C). The lubricant (A) includes a sulfur-containing ester (A3). The amount of the lubricant (A) ranges from 50 to 90 wt %, the amount of the ester (B) ranges from 1 to 20 wt % and the amount of the sulfur-containing ester (A3) ranges from 5 to 20 wt %, to a nonvolatile component of the finish.
摘要:
A process for imparting flame resistance and the flame resistant fabrics produced by such process are provided. The process for imparting flame resistant properties involves treating a target fabric with one or more flame retardant chemicals (and, preferably, a softening agent) and then curing the treated fabric to durably affix the flame retardant to the fabric. In many cases, it may be desirable to subject the treated fabric to mechanical face finishing to increase softness. Optionally, stain release agents, soil repellent agents, permanent press resins, and the like may be added to the bath of flame retardant chemicals, eliminating the need for one or more additional manufacturing processes. Alternately, soil repellent agents may be applied to only one side of the treated fabric after the application of the flame retardant chemicals. The present fabrics exhibit improved performance and tear strength, even after repeated launderings, as compared to conventionally treated fabrics.
摘要:
The invention relates to a mixture, comprising (A) 10 to 90 wt. % of at least one C6 to C18 alkyl ester, or C5 to C8 cycloalkyl ester of 2-cyano-3,3-diphenylacrylic acid and (B) 90 to 10 wt. % of at least one further compound, with at least one UV absorption maximum in the range 280 to 450 nm and structurally different from compound (A). Said mixture is suitable for the protection of human skin from damaging UV radiation and for the protection of coloured textile materials from colour fading.
