Each cup support comprises a convex member. Each cup support may include a plurality of apertures formed through the convex member. Each cup may further include a plurality of protrusions to space the cups of the garment away from the convex member. The apparatus includes a water permeable bag extending around the flexible panel. In this case, the flexible panel may be attached to the water permeable bag.
摘要:
A method and apparatus are described for controlling a coating head, which exerts a nip pressure to a fibrous web to be coated while the fibrous web is supported by a backing roll. An output signal of a sensor integrated within the backing roll is read, thus producing a measured indication of the nip pressure. A number of actuator control values are derived at least partly from said measured indication of the nip pressure. Said actuator control values are delivered as commands to a number of respective actuators that contribute to creating the nip pressure, to control an amount of a coating substance on the fibrous web in the coating head.

摘要:
The purpose of the present invention is to provide a fabric for an air bag that, during high-pressure deployment at high speed, maintains low air permeability as an air bag and is capable of maintaining the low air permeability even after exposure to heat. This fabric for an air bag comprises a synthetic fiber and is characterized by the contact angle of a circumscribed circle at intersecting sections in which the warp thread and the weft thread come in contact in the cross section of the fabric is at least 80° in both the warp thread direction and the weft thread direction.
摘要:
A glazing method for improving abrasion resistance using a heated smooth roll to melt the lower-melting-point portion of bicomponent fibers as the spunbond web passes over the heated smooth roll. Because there is no external pressure exerted in a nip by an opposing second roller, as in calendering, the outer surface of the web which does not contact the heated smooth roll remains essentially unchanged and the nonwoven fabric exhibits no compression as a result of the glazing process. The roll temperature and dwell time (roll diameter, wrap angle and line speed) are controlled for the purpose of surface treating only one side of the nonwoven fabric to improve abrasion resistance while allowing the air permeability and web thickness to remain essentially unchanged.
摘要:
The present invention relates to a light-emitting fabric, in which acrylic optical fibers and general fibers are woven together, and light is emitted to the surface of the fabric through the optical fibers floating on the surface of the union fabric. According to the present invention, part of the clad portion of the optical fibers is removed by melting so as to prevent the total reflection of the clad portion and to emit high-brightness patterns or characters having a higher brightness than those emitted by optical fibers having a conventional clad portion. Also, a semi-circular core portion is flattened so as to prevent the light from being refracted unnecessarily, and thus the high-brightness light-emitting fabric which can express complex patterns or characters at a higher resolution without emitting environmental pollutants can be provided.
