    摘要: A nonwoven fabric having no pattern and composed of 100% synthetic fibers, wherein individual fibers are held together by three-dimensional entanglement into a stabilized sheet form without being subjected to any bonding treatment, which nonwoven fabric has a structure characterized by a specific volume of the nonwoven fabric of 3.5 cm.sup.3 /g or less, a bending index (in terms of R) of individual fibers of 4.0 or more, and a strength efficiency (in terms of S) of the nonwoven fabric of 90% or more. Such a nonwoven fabric has excellent properties which are comparable to conventional woven fabrics in not only hand but also practical performance characteristics. This nonwoven fabric is manufactured by a method which comprises placing on a substantially smooth supporting member a web, 35 to 170 gm/m.sup.2 in basis weight, composed of highly shrinkable synthetic fibers having a potential heat shrinkage of 50% or more, exposing said web to the impact of fine jet streams of water discharged under a pressure of 10 to 35 kg/cm.sup.2, whereby allowing individual fibers to entangle one another, thereafter subjecting the web to wet heat treatment at free length conditions to allow the web to shrink by 50% or more in area, drying the shrunk web at a temperature at which no change takes place in the shape and internal structure of individual fibers, and then subjecting the dried web to heat setting under an applied pressure of 200 g/cm.sup.2 or more.

    摘要: A method capable of bonding lengthy horizontal plate materials and lengthy vertical plate materials to each other without skill of a worker and with uniform and beautiful finish, and a press-bonding jig used for the method. The press-bonding jig is set at a workbench, which has a vertical wall section for positioning lengthy horizontal plate materials and lengthy vertical plate materials, or at a member disposed around the workbench to press and fix the respective plate materials to each other along edges thereof, comprising a frame having a sufficient length to support the plate materials and holding air cylinders for actuating rubber pads in a pressing direction, and means for starting and stopping the air cylinders. The press-bonding jig is used to made complicated manual fixing operation needless and enables bonding in a short time with a beautiful finish.

    摘要: Surface-modified cellulose acetate filaments having a microporous structure located in the peripheral surface layer thereof are prepared by bringing non-modified cellulose acetate filaments which have an average degree of acetylation of 50 to 62% into contact with an organic solvent which is capable of dissolving or swelling the non-modified filaments and by rapidly evaporating the solvent from the filaments. The microporous structure causes the surface-modified filaments to exhibit a desirable silklike touch and an increased intensity in dye exhaustion of from 1.1 to 2.0 times that of the non-modified filaments.
