Abstract
Abstract A synthetic phosphorescent fiber having a sectional dimension of less than approximately 0.015 in. and a method of manufacturing the fiber. The fiber comprises a body portion made of a flexible and durable polymeric material which is at least partially translucent and a plurality of phosphorescent particles in the body portion. The particles have a miximum particle size which is less than one half of the sectional dimension of the fibers and between approximately 0.0075 in. and 0.0005 in. and they have a mean particle size which is greater than approximately 0.0025 in. The fibers are manufactured in accordance with the method by mixing appropriately sized phosphorescent particles with a coupling agent, mixing the particles and the coupling agent with a suitable polymer and extruding the resultant mixture to form fibers. The fibers can be effectively utilized for artificial hair for toy dolls as well as for various other applications.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
108 words
In a doll construction of a type including a doll body having a head and a plurality of flexible stranded artificial hair fibers on said head, the improvement comprising at least a portion of said hair fibers being phosphorescent and being extruded from a material comprising a flexible polymeric material which is at least partially translucent and a plurality of phosphorescent particles in said polymeric material, said translucent hair fibers having cross sectional dimensions of less than approximately 0.015 in., said phosphorescent particles having a maximum particle size which is between 0.0075 in. and 0.0005 in. and which is less than one half of said cross sectional dimension.
Claim 2
Dependent Claim
108 words
In a doll construction of a type including a doll body having a head and a plurality of flexible stranded artificial hair fibers on said head, the improvement comprising at least a portion of said hair fibers being phosphorescent and being extruded from a material comprising a flexible polymeric material which is at least partially translucent and a plurality of phosphorescent particles in said polymeric material, said translucent hair fibers having cross sectional dimensions of less than approximately 0.015 in., said phosphorescent particles having a maximum particle size which is between 0.0075 in. and 0.0005 in. and which is less than one half of said cross sectional dimension.
Claim 3
Dependent Claim
21 words
In the doll construction of claim 1, said phosphorescent particles having a mean particle size of greater than approximately 0.00025 in.
Claim 4
Dependent Claim
21 words
In the doll construction of claim 2, said translucent hair fibers having sectional dimensions of between 0.002 in. and 0.004 in.
Claim 5
Dependent Claim
26 words
In the doll construction of claim 2, said polymeric material comprising a material selected from the group consisting of polyamides, polyesters, polyolefins, polyacrylonitriles and polyvinyl chlorides.
Claim 6
Dependent Claim
26 words
In the doll construction of claim 2, said phosphorescent particles comprising a material selected from the group consisting of zinc sulfide, cadmium sulfide and calcium sulfide.
Claim 7
Dependent Claim
96 words
In the doll construction of claim 2, said material from which said fibers are extruded further comprising a coupling agent, said coupling agent being mixed with said phosphorescent particles before said phosphorescent particles are mixed with said polymeric material and being of a type which is suitable for coating said phosphorescent particles, said phosphorescent particles and said coupling agent being mixed together with said polymeric material to achieve a substantially uniform distribution of said phosphorescent particles therein, said coupling agent operating to enhance the uniformity of the distribution of said phosphorescent particles in said polymeric material.
