Wristbands and headbands

Abstract

A band includes a split compound yarn and a rubber yarn woven together with the split compound yarn. The band is made by means of a process including a step of making the compound yarn, a step of providing the rubber yarn, a step of weaving the compound yarn together with the rubber yarn so as to form the band, and a step of washing the band so as to split the compound yarn.

1 . A band including a split compound yarn and a rubber yarn woven together with the split compound yarn.  
   
   
       2 . The band according to  claim 1  wherein the band is made by means of a process including the steps of: 
 making the compound yarn;    providing the rubber yarn;    weaving the compound yarn together with the rubber yarn so as to form the band; and    washing the band so as to split the compound yarn.    
   
   
       3 . The band according to  claim 2  wherein the compound yarn is made of first material and second material.  
   
   
       4 . The band according to  claim 3  wherein the step of making the compound yarn includes the steps of: 
 melting and extruding the first material;    melting and extruding the second material;    pumping the molten first material and the molten second material at predetermined rates;    spinning filaments from the molten first material;    spinning filaments from the molten second material;    cooling the filaments;    extending the filaments so as to form the compound yarn;    heating and setting the compound yarn; and    reeling the compound yarn.    
   
   
       5 . The band according to  claim 4  wherein the step of making the compound yarn includes a step of facilitating the splitting of the compound yarn.  
   
   
       6 . The band according to  claim 5  wherein the step of facilitating the splitting of the compound yarn is a chemical step.  
   
   
       7 . The band according to  claim 6  wherein the chemical step is taken in the step of melting and extruding one of the first material and the second material.  
   
   
       8 . The band according to  claim 7  wherein the chemical step is a step of adding nucleated agent to one of the first material and the second material.  
   
   
       9 . The band according to  claim 8  wherein the nucleated agent is selected from a group of CaSiO 3 , SiO 2  and MoS 2 .  
   
   
       10 . The band according to  claim 7  wherein the chemical step is a step of adding splitting agent to one of the first material and the second material.  
   
   
       11 . The band according to  claim 10  wherein the splitting agent is superfine Teflon.  
   
   
       12 . The band according to  claim 7  wherein the chemical step is a step of making one of the first material and the second material via mixing 20-80% of amorphous polymer with 80-20% of crystal polymer.  
   
   
       13 . The band according to  claim 7  wherein the chemical step is a step of melting the first material and the second material at carefully calculated temperatures so that the stickiness of the first material to the second material is low.  
   
   
       14 . The band according to  claim 5  wherein the step of facilitating the splitting of the compound yarn is a mechanical step.  
   
   
       15 . The band according to  claim 14  wherein the mechanical step is taken in the step of spinning the compound yarn.  
   
   
       16 . The band according to  claim 15  wherein the mechanical step is reeling the compound yarn at a rate of 3000-8000 meter per minute so that the first material crystallizes at a rate adequately different from a rate at which the second material crystallizes.  
   
   
       17 . The band according to  claim 1  wherein the band is a wristband.  
   
   
       18 . The band according to  claim 1  wherein the band is a headband.  
   
   
       19 . The band according to  claim 3  wherein the first material is such as nylon.  
   
   
       20 . The band according to  claim 3  wherein the second material is polyester.
