摘要:
An artificial hair bundle (10) is made up by mixing a first artificial hair made of a polyester resin (1, 2) and a second artificial hair made of a polyamide resin (5, 6), and the first artificial hair (1, 2) is made of polyethylene terephthalate and polybutylene terephthalate, having a cross-sectional size and bending rigidity similar to those of natural hair, wherein the bending rigidity is in the range of about 6.5 to 7.8×10−3 gf·cm2/strand at humidity 40%, and the first artificial hair (1, 2) suppresses bundling of the second artificial hair (5, 6), and the first and the second artificial hairs (1, 2, 5, 6) behave similarly to natural hair.
摘要:
An artificial hair and a wig using the same are provided which have such feeling as appearance, tactile and texture and preferable physical properties similar to natural hair, wherein an artificial hair 1 has a sheath and core structure comprising a core portion 1B and a sheath portion 1A covering said core portion 1B, and by making the core portion 1B of a polyamide resin, especially a semi-aromatic polyamide resin, and the sheath portion 1A of a polyamide resin having a rigidity for bending lower than the core portion 1B, especially a linear saturated aliphatic polyamide resin, the rigidity for bending, for example, can be made to have a value close to that of natural hair, and further its variation behavior depending upon humidity can be controlled quite similar to natural hair, thereby the wig made of it as a material has natural feeling, so that the wig having an excellent appearance can be offered.
摘要:
An artificial hair and a wig using the same are provided which have the property of thermal deformation expanding upon heating by a hair drier or others used for hair styling.The artificial hair 1 is made by mixing at the pre-determined ratio a semi-aromatic polyamide having a glass transition temperature between 60-120° C. and a resin not expanding in said temperature range. The artificial hair may have a sheath/core structure comprising a core portion 5B and a sheath portion covering the core portion. As the resin not expanding in said temperature range, polyethylene terephthalate or others can be used, and as the sheath, nylon 6 or nylon 66 can be used. Said artificial hair 1 can maintain its shape at room temperature or after shampooing due to thermal deformation by heating in steam atmosphere at temperature of glass transition or higher or about 80-100° C.

摘要:
A synthetic fiber having an uneven surface structure consisting of wrinkles having ridges and recesses of the surface of the fiber and not presenting specular luster, which may be used, for example, as artificial hair for wigs, can be produced easily and stably by melt-spinning a starting synthetic resin such as nylon and passing the spun monofilament through a cooling bath at a temperature not lower than 30.degree. C. for a period of time sufficient for developing wrinkles in its surface. Inclusion of a pigment such as carbon black in an appropriate amount in the starting material is effective in providing dense distribution of wrinkles.

摘要:
A recycled plastic material is made from laser-engraved thermoplastic, metal-containing thermoplastic, thermoplastic used in an inkjet apparatus, or thermoplastic to which an ink or its composition have stuck. This recycled plastic material is manufactured by pulverizing any of these thermoplastics, cleaning the pulverized thermoplastic, removing a cleaning solution from the cleaned thermoplastic to dry it, and removing the dried thermoplastic solid matter other than the thermoplastic.
摘要:
The present invention relates to a discharge recovery processing of an ink jet recording apparatus which forms an image on the recording medium by discharging the ink. The invention aims to prevent the increase in the running costs and the shortened life of a waste ink tank by preventing the wasteful ink consumption which may be caused by the dual use of an automatic recovery processing and a manual recovery processing after the replacement of an ink tank.Also, the invention further aims to provide an ink jet recording apparatus with high safety and reliability as well as effecting an appropriate recovery by controlling the movement of head in involving the recovery.
摘要:
An apparatus for recording an image by discharging an ink droplet to a recording medium includes a timer for setting a predetermined time in accordance with the type of the recording medium so that the recording operation is interrupted or conveyance of the recording medium is interrupted during the predetermined time in order to prevent contact between a previously discharged recording medium and a recording medium which is being discharged so that generation of smear and adhesion between recorded recording mediums are prevented regardless of the type of the recording medium.
摘要:
A display unit is provided so as to be rotatable with respect to a main body of an electronic apparatus. An inlet for manually inserting a sheet is provided in the vicinity of the center of rotation of the display unit, and a sheet feeding device capable of continuously feeding sheets is provided so as to be detachable with respect to the inlet. It is thereby possible to supply a sheet from the front side of the electronic apparatus.
