Abstract

A process for manufacturing a web material is disclosed. The process generally provides the steps of: a. providing a pulp material comprising fibers and vessels; b. separating said vessels from said fibers in said pulp material to form a slurry having at least about 7 percent less vessels per meter than said pulp material; and c. processing said slurry to form said web material.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
       1. A process for manufacturing a web material, the process comprising the steps of:
 a) providing a pulp material comprising fibers and vessels; 
 b) separating said vessels from said fibers in said pulp material to form an accepts stream having at least about 7 percent less vessels per meter than said pulp material, and a rejects stream having about 15% more vessels per meter than said pulp material; 
 c) processing the accepts stream to form said web material. 
 
     
     
       2. The process of  claim 1  further comprising the step of separating said vessels from said fibers with a hydrocyclone. 
     
     
       3. The process of  Claim 1  further comprising the step of processing said rejects stream to create a second accepts stream and a second rejects stream, said second accepts stream having less vessels than said second rejects stream. 
     
     
       4. The process of  claim 3  further comprising the step of adding said second accepts stream to said accepts stream. 
     
     
       5. The process of  claim 1  wherein said step c) further comprises the step of depositing said accepts stream on a foraminous forming wire. 
     
     
       6. The process of  claim 5  further comprising the step of dewatering said accepts stream disposed upon said foraminous forming wire to a fiber consistency ranging from about 40 percent to about 80 percent. 
     
     
       7. The process of  claim 6  further comprising the step of transferring said dewatered accepts stream to a foraminous forming member. 
     
     
       8. The process of  claim 7  further comprising the step of dewatering said accepts stream disposed upon said foraminous forming member. 
     
     
       9. The process of  claim 8  further comprising the step of transferring said dewatered accepts stream from said foraminous forming member to a surface of a through air dryer. 
     
     
       10. The process of  claim 9  further comprising the step of creping said dewatered accepts stream from said surface of said through air dryer to form said web material. 
     
     
       11. The process of  claim 10  further comprising the step of winding said web material.
