A method of electroplating an object to be plated attached to a lower portion of a plating bath constituted by draining used plating solution and supplying new plating solution at every plating procedure. The method has a step of supplying additional current so that the object to be plated always has cathode potential, while the object to be plated is being dipped in the plating bath and electroplating is not carried out.

Disclosed is an elastic absorbent which comprises a substantially homogeneous mixture of pulverized cellulose pulp and staple fibers of a split yarn obtained by splitting a tape-form oriented laminate comprising at least one layer of a synthetic resin having a high melting point and at least one layer of a synthetic resin having a low melting point, in which the layer of the synthetic resin having a low melting point is at least partially exposed to the surface. Another elastic absorbent comprises an intermediate layer of a powdery polymeric water-absorbing agent, which is interposed between upper and lower layers, each of the upper and lower layers comprising a substantially homogeneous mixture of pulverized cellulose pulp and staple fibers of the same split yarn as mentioned above. At the crossing points of the staple fibers, of the split yarn, the synthetic resin having a low melting point is at least partially fusion-bonded and the staple fibers of the split yarn are connected to one another in the state where the cellulose pulp is partially enclosed therein.

A monofilament of a thermoplastic resin having a high tenacity is produced by a process in which a monofilament is melt spun at a temperature of 220.degree. C. to 310.degree. C. from a thermoplastic resin through a nozzle having a cross-sectional area S (mm.sup.2) satisfying the following equations: ##EQU1## wherein I is a maximum cross-sectional secondary moment max (Ix, Iy) (i.e., the maximum secondary moment in the cross-sectional secondary moments with respect to the main x axis and y axis passing through the center of the gravity of the cross-section); and, then, is subjected to a multi-stage stretching under the conditions satisfying the following equations: ##EQU2## wherein i is a number of stretching stages, e is a base of natural logarithm (i.e., 2.71828), V.sub.1 is the first take-off linear velocity (m/min), V.sub.i+1 is the final take-off linear velocity (m/min) at the i-stretching stage, DR.sub.Ti is the total stretching ratio at the i-stretching stage, DR.sub.Tiw is the DR.sub.Ti from which the monofilament begins to become whitened at the i-stretching stage, T.sub.m is the melting point of the thermoplastic resin and .theta..sub.i is the temperature of the filament at the i-stretching stage.

An electrode assembly including a first cathode member provided with a hole enclosed by a frame portion. The frame portion surrounding the hole has a contact surface that comes into contact with an object to be plated at one of its surfaces, and an insulating member is provided with holes and enclosed by a frame portion, with one surface of the frame portion placed on top of another surface of the frame portion of the first cathode member. A second cathode member also provided with a hole enclosed by a frame portion, with one surface of the frame portion placed on top of one surface of the other frame portion of the insulating member. The smallest bore diameter at the hole of the second cathode member is larger than the smallest bore diameter at the holes and of the insulating member.
摘要:
An apparatus for the preparation of an elastic absorbent composed of a mixed web. Elements of the apparatus can include two supply hoppers for separately supplying pulverized pulp and staple fibers of a synthetic fiber split yarn at a constant mixing ratio with each hopper having a pair of confronting moving belts, two guide mechanisms located below the hoppers, a pair of nip rollers located below the guide mechanisms, a garnet roll located below the pair of nip rollers, a vacuum device located below the garnet roll, and a mesh belt located between the vacuum device and the garnet roll. Each guide mechanism in the apparatus may include at least two gear guides arranged in series. The apparatus operates by feeding the pulverized pulp and the staple fibers of the split yarn from the hoppers to the nip rolls via the guide mechanisms. The nip rolls compress the material, which is then disintegrated and mixed by the garnet roll. The mixture is pulled onto the mesh belt by the vacuum device.
