摘要:
In one aspect, a composition for treating fibers comprises an acidic aqueous or aqueous-based continuous phase and a liquid repellent phase comprising a dendrimer component and/or non-dendrimer alkyl urethane. The treatment composition, for example, can have pH of 2.5 to 6.5. In some embodiments, carboxylic acid is employed in the treatment composition for providing the acidic character of the aqueous or aqueous-based continuous phase. Moreover, the treatment composition can further comprise at least one of an acid stain resist component and soil release component. In some embodiments, fibers treated with compositions described herein exhibit ionic character.

Carbon fibers having a high tensile strength satisfy the relationship represented by formula (1) and one of the relationships represented by formulas (2) to (5): La≧1 (1), La≦−0.5+0.01×TM when 170≦TM≦230 (2), La≦−37.3+0.17×TM when 230
摘要:
A sliding member having more improved wear resistance is provided at a low cost. A sliding member is provided with: a substrate which is made of a nonwoven fabric; and a base resin which includes a phenol resin and which is impregnated into the substrate. The nonwoven fabric is preferably a bonded nonwoven fabric which is produced by a thermal bonding method, a binder method or the like and which has a strength that can tolerate the tension applied to the substrate in the step for producing the sliding member. It is preferable that the nonwoven fabric is made of a polyethylene terephthalate (PET) fiber which exhibits a high affinity for the phenol resin. Further, it is preferable that the phenol resin contains a chelating agent which can increase sites of crosslink with hydroxyl groups of the phenol resin.

Fiber for reinforcing rubber products, which comprises fiber coated with a coating film formed by a treating agent, wherein the treating agent comprises a rubber latex containing at least a vinylpyridine/styrene/butadiene terpolymer, a latex of an acrylonitrile/butadiene/styrene terpolymer, and a water-soluble condensate of resorcinol and formaldehyde.
摘要:
A filter element for use in a smoking article and providing filtration of particulate material and gaseous components of mainstream smoke is provided. The filter element includes a segment of fibrous tow comprising a plurality of individual filaments, wherein each individual filament includes a plurality of adsorbent material particles at least partially encapsulated with a removable encapsulant imbedded therein. The individual filaments may further include an outer coating that provides a plurality of reactive groups adapted for reaction with one or more components of mainstream smoke. Alternatively, the multifunctional filter element combines different fibrous filter materials, such as cellulose acetate or polyolefin filaments combined with activated carbon filaments and at least one of ion exchange filaments and catalytic filaments. A method of providing a cellulose acetate fibrous tow containing an imbedded adsorbent material is provided, wherein a plurality of encapsulated adsorbent particles are mixed with a cellulose acetate dope.

摘要:
This invention relates to tacky finishes and to the textile materials and articles treated with the tacky finishes. The tacky finishes provide improved processing features for end-use articles that contain such finishes. The tacky finish may be combined with other adhesion promotion finishes in the treatment of textile materials. The textile materials and articles may be used as rubber reinforcing materials, such as automotive tire cap ply, single end tire cord, carcass reinforcement and side wall reinforcement. End-use articles that contain the treated textile materials include rubber-containing materials such as automobile tires, belts, and hoses. This invention also relates to the methods for manufacturing the treated textile materials and articles.
摘要:
A milled carbon fiber is made of a carbon fiber, which is coated with a sizing at an amount X between 0.05 and 0.30 weight %. The sizing is formed of a heat resistant polymer or a precursor of the heat resistant polymer. The amount X of the sizing is expressed with a following formula: X = w o - w 1 w o × 100 where W0 is the weight of the carbon fiber with the sizing, and W1 is the weight of the carbon fiber without the sizing.
