摘要： PURPOSE:To obtain the subject mixed nonwoven fabric more easily and stably (including product performance), at lower cost, in larger quantities, while making the best use of the characteristics of cottonlike chitin fibers and silk fibers. CONSTITUTION:Subordinate silk yarns (waste silk yarns from cocoons sorted off, rubbish produced in silk yarn manufacturing process, rubbish produced in silk yarn weaving process) are scoured to a half to 70% degree into floss silk, which is cut into short or medium fibers (or, various kinds of floss silk may be cut into such fibers). The fibers are subjected to alkali scouring or high-pressure scouring process followed by post-treatment such as neutralization and/or washing, and the resultant fibers are opened into finished silk fibers. A highly transparent chitin solution prepared by purification of chitin extracted from a crustacean is subjected to wet spinning followed by cutting into short or medium fibers (cottonlike chitin fibers). Next, the finished silk fibers and cottonlike chitin fibers are mutually homogeneously blended at the weight ratio of (10:90) to (90:10) to form a web as the objective mixed nonwoven fabric.

摘要： PURPOSE:To provide a throw-away diaper which is bulky and soft. CONSTITUTION:A top sheet 2 of the absorber part of this throw-away diaper 1 is formed of a liquid permeable non-woven fabric and an inside layer 3 is formed by sandwiching a polymer absorbent 5 with fluff pulp, sheets 4. Fine pieces 6 of selvage parts which are the loss fabrics of the span bonded non- woven fabrics are compounded in these fluff pulp sheets 4 in a uniformly dispersed state of 30 to 60wt.% of the fluff pulp sheets 4.

摘要： PURPOSE:To provide a waste paper-regenerated heat-insulating material (Ecowool), and provide a blowing or blasting heat insulation-applying method using the waste paper-regenerated heat-insulating material (Ecowool). CONSTITUTION:Waste paper is fed from hydraulic waste paper-distributing tables 1 to a belt conveyer 2, and carried into a roughly grinding machine 3. The roughly ground waste paper pieces are fed into a cyclone separator 5 through a carrier 8 equipped with a variator with the air pressure of a blower 4 for carriage. Dusty ground waste paper pieces having under sizes are collected into a duct collector 6, and the ground waste paper pieces having upper sizes are collected into an intermediate storage tank 7 equipped with a mixer. The ground waste paper pieces stored in the intermediate storage tank 7 are fed into a grinder 10 with the air pressure of a blower 9 for carriage. The grinder 10 is assembled with the first cyclone separator 12. The waste paper pieces are fed into the another cyclone separator 12 with the air pressure of a blower 11 for carriage. Also in the case, the dusty waste paper pieces having the under sizes are collected into a dust collector 13, and the dusty waste paper pieces are stored into a bagging and storing tank equipped with a mixer.

摘要： PURPOSE: To transfer fibers in a uniform distribution state onto a collecting surface by stripping the fibers on a cylinder by a supply air stream between a card cylinder and a worker. CONSTITUTION: In the production of a nonwoven fabric, stock fibers are supplied to the card cylinder 1 and are uniformly opened via the worker 5. The fibers are stripped from the cylinder 1 by the supply air stream 6 passing a supply air passage 12 formed in the narrowest spacing between the cylinder 1 and the worker 5 and are sent to a suction passage 3. The supply air stream 6 comprising partial steams 10 and 11 and the supply air stream 7 passing the supply air passage 6 between the cylinder 1 and a cylinder cover 9 on the retreat side thereof act on the suction passage 3. The fibers entrained to the worker 5 by the supply air stream 18 passing the supply air passage 16 between the worker 5 and the worker cover 17 are returned to the suction passage 3. Further, the fibers passing the suction passage 3 are uniformly transferred onto the collecting surface 2 by the negative pressure of a suction box 4 divided to plural suction areas 4a.

摘要： PURPOSE: To effectively and softly open a woven or nonwoven fabric made of conjugated fibers comprising polyamide and polyester as a base material by treating it with a specific treating liquid so that the physical properties are not deteriorated and the yellowing is not generated. CONSTITUTION: The woven or nonwoven fabric made of conjugated fibers (formed in a separated or sea-island type, for example) comprising polyamide and polyester as a base material is subjected to the opening treatment at 25-60 deg.C using an acidic treating liquid having 10-75 wt.% concentration of the following materials for opening the fabric and dissolving and removing the polyamide. The treating liquid comprises preferably an organic acid represented by formula I wherein R is Cn H2n+1 .OH or OH [(n) is 1-4]; X is OH or Cn H2n [(n) is 0-4]; (m) is 1-2} and/or an inorganic acid represented by formula II (wherein R1 is H; X is Cl , SO3 , SO4 or PO3 ) and a surfactant represented by formula III [wherein R2 is Cn H2n+1 [(n) is 8-18]; R3 and R4 are each CH3 , Cn H2n [(n) is 1-3] or H; X is COO , SO3 or PO3 ]. After the opening treatment, the remaining polyester fibers have 0.02-0.80 denier fineness to enhance the softness of the fabric.
