Fibers for hair use in which the drawback of curling property is imparted without imparting features of human hair, such as flame resistance, heat resistance, touch feeling, and which are reduced in quality unevenness. The fibers are a bundle of fibers for hair use which comprises a mixture of 10 to 90 parts by weight of human hair (A) and 90 to 10 parts by weight of polyester fibers (B) having an LOI-value of at least 25, a thermal shrinkage ratio at 180° C. of at most 5%, and a single fiber fineness of 20 to 100 dtex, wherein the component (B) is polyester fibers formed from a composition obtained by melt-kneading a polyalkylene-ethylene terephthalate and a copolymer comprising polyalkylene-ethylene terephthalate as the main component (C) together with a phosphorus compound flame retardant (D) and/or a bromine compound flame retardant (E).
摘要:
In a pillow comprising at least three substantially flat bags successively layered, each of intermediate layer bags other than top and bottom layer bags is provided with closure means and provided substantially at the middle of each intermediate layer bag with a pocket having also its own closure means through which cedar chips are enclosed in this pocket. Chips of synthetic resin are enclosed in one of the outermost layer bags and a fibrous member containing aromatic essence of Japanese cypress is enclosed in the other outermost layer bag. No content is enclosed in the bags other than the intermediate layer bags in their regions over- and underlying the pockets so that a recess having no significant thickness is formed in those regions over- and underlying the pockets. The regions of the intermediate layer bag(s) extending adjacent the periphery of the pillow may be loaded with cedar chip bags so as to adjust a thickness of the pillow in its peripheral region. In this manner, the novel pillow supports the user's head and neck with comfortable stability and contributes to elimination of minute forms of life such as ticks as well as to a desired aroma-therapeutic effect.

A monomer mixture (B) containing a vinyl monomer having a functional silyl group of the general formula (ii) is subjected to emulsion polymerization in an aqueous solution of a water-soluble resin (A) having a functional silyl group of the general formula (i) the water-soluble resin [A] is synthesized using, as a polymerization solvent, a water-soluble organic solvent containing a (poly)ethylene glycol monoalkyl ether of the general formula HO--(CH.sub.2 CH.sub.2 O).sub.n --R.sup.3 or a (poly)propylene glycol monoalkyl ether of the general formula HO--(C.sub.3 H.sub.6 O).sub.n --R.sup.4 ; ##STR1## wherein R.sup.1 and R.sup.2 each independently is a monovalent group selected from the class consisting of alkyl groups containing 1 to 10 carbon atoms, aryl groups and aralkyl groups, X is a group selected from the class consisting of halogen atoms, alkoxy groups, a hydroxy group, acyloxy groups, an aminoxy group, a phenoxy group, thioalkoxy groups and an amino group, a and b each independently is an integer of 0 to 2, R.sup.3 and R.sup.4 each is an alkyl group containing 1 to 10 carbon atoms and n is an integer of 1 to 10 and wherein, when two or more R.sup.1 and/or R.sup.2 or X groups are bound to Si, they respectively may be the same or different.
摘要:
A remote supervisory and controlling system for remotely supervising and controlling loads in time-divisional multiplex transmission of control units and monitor data between a central control and terminal units each connected to the central control unit through a two-wire line. Supervision and control of the overall system can be carried out from a plurality of locations so that failure of a central or host computer will not render the overall system inoperative.

摘要:
An information recording medium has such a structure that a disc-shaped substrate is provided with a hole at its central part, an inner-side non-recording zone is provided around the periphery of said hole, an outer-side non-recording zone is provided inside the outer periphery of the substrate, a recording zone is provided between both non-recording zones on the substrate, and a flexible disc-shaped resin film having a hole at its central part is joined to each of the non-recording zones on the substrate in such a state that the resin film is substantially not in contact with the recording zone on the substrate to form a gas layer over the recording zone. A process for producing the recording the medium is also disclosed.

A magnetic recording medium having a thin magnetic recording metal film formed on one surface of a non-magnetic base is disclosed. A thin cured epoxy resin film comprising an epoxy resin having an epoxy equivalent of from 400 to 3,000 and a curing agent made of an aliphatic amine having two or more amino groups and three or more amino active hydrogen atoms in the molecular chain is formed on either the thin magnetic metal film or the surface of the non-magnetic base opposite the thin magnetic metal film or both. A process for producing such magnetic recording medium is also disclosed.
摘要:
A flame retardant polyester fiber for artificial hair, which is obtained by melt spinning a composition as a mixture of 100 parts by weight of (A) a polyester made of one or more of polyalkylene terephthalate and a copolymer polyester comprising polyalkylene terephthalate as a main component with 5 to 30 parts by weight of (B) a brominated epoxy flame retardant. The present invention also relates to the polyester fiber for artificial hair which has at least one modified cross-section, is a mixture with a fiber having a modified cross-section, and has a mixing ratio of the fiber having a round cross-section to the fiber having a modified cross-section is 8:2 to 1:9, and to the flame retardant polyester fiber for artificial hair which further comprises a hydrophilic fiber treating agent attached thereto, and thus has excellent smooth feeling, combing properties, and flame retardance.
