It is an object of the present disclosure to provide a continuous fiber reinforced resin composite material having good acoustic emission signals, high strength, elastic modulus, and water absorption characteristics, and a method of producing the same. The continuous fiber reinforced resin composite material contains continuous reinforcing fibers and thermoplastic resin, wherein an acoustic emission (AE) count A determined by the following formula is 0.30 or less: (AE count A)=(number of AE signals having amplitude of 40 dB or more and duration of 3500 seconds or shorter)/(total number of AE signals).

A fabric treatment composition is provided that includes at least one zeta potential modifier, a fluoropolymer and a hydrophobic agent with a melting point or glass transition temperature below 100 C., for imparting fabric protection benefits to a fabric, such as improved stain and soil resistance, oil repellency, water repellency, softness, wrinkle and damage resistance, and better hand feel. Fabric treatment compositions can be used as a pretreatment prior to washing, through soaking, or added to the treatment liquor, that is either the wash or rinse cycle of an automatic washing machine, to first provide and then maintain and refresh the fabric protection benefits imparted to the fabric. Following use of a first treatment composition, protective benefits are maintained and refreshed by means of a second treatment operation employing a second treatment composition. The second treatment composition may have lower active levels of the protective agents to provide for economical and periodic maintenance of the imparted fabric protection benefits.

Functionalized fibers adapted to remove contaminants from water and soil are produced in accordance with a single-step process that involves treating an acrylic fiber with an amination reagent to form a functionalized acrylic amino fiber. By way of another single-step process, functionalized acrylic amino fibers are treated with an alkylating reagent to form functionalized acrylic quaternary amino fibers.
