Abstract: Provided are a space debris removing device and a method which enable easy installation of a deceleration device to space debris undergoing a tumbling motion. The space debris removing device includes: a propulsion device (3) for performing approach and attitude control on target debris (1); a capture device (4) having a harpoon (41) which can be ejected toward the target debris (1); an observation device (5) for calculating a capture position (E) and a capture attitude at which the harpoon (41) can be driven into a tank (11) (hollow portion) of the target debris (1) by observing a motion of the target debris (1); a deceleration device (6) directly or indirectly connected to the harpoon (41), for decelerating the target debris (1); and a body part (21) on which the propulsion device (3), the capture device (4), the observation device (5), and the deceleration device (6) are mounted.

Abstract: The present invention provides a method of producing a softening agent in which a silicone resin containing particular functional groups, a particular emulsifier and a particular antistatic agent are dispersed stably in an aqueous medium in a particular ratio, and which can give durable slippery touch, softness and processability at the same time to fibers after treatment. The invention also provides an industrially advantageous method of producing acrylic fibers which have animal hair-like touch and processability by one-step treatment, by fixing said softening agent to the acrylic fibers.

Abstract: Process for imparting an animal hairlike hand to acrylic fibers by mixing a silicone resin and a polyoxyethylene alkylphenyl phosphate while adding water thereto to form an emulsion of weak acidity, applying the emulsion to swollen gelly acrylic fibers, drying the resultant fibers and applying a spinning oil to the dried fibers.

Abstract: Acrylic synthetic fibers having an interfiber entanglement coefficient of 10-40, an interfiber entangling force after hot-water treatment of not greater than 50 mg and a specific type of silicone resin deposited on the surfaces of the fibers.
