#8: Technical Nylon - Katie Rozeboom

Technical Nylon video #1

Nylon is a synthetic polymer fiber first produced by DuPont in 1935. It's made through a condensation polymerization process involving monomers like hexamethylenediamine and adipic acid for nylon. The polymerization occurs at high temperatures in batch reactors, followed by cooling and cutting the polymer into pellets for further use. 

In the melt-spinning process, these nylon pellets are melted, extruded through a spinneret to form filaments, cooled, and stretched to align the polymer molecules, increasing the fiber's strength and elasticity. The fibers are then wound and often heat-set for stability.

Nylon is known for its strength, elasticity, abrasion resistance, low moisture absorption, and chemical resistance. Its applications range from textiles (clothing, upholstery) to industrial uses (ropes, conveyor belts), automotive components, consumer goods, and sporting equipment due to its durability and flexibility.

The process of making nylon starts with polymerization, where monomers react to form long chains of nylon. The molten nylon is cooled, cut into pellets, and then melted again for melt spinning. The molten nylon is pushed through a spinneret to create fibers, which are cooled and stretched to increase strength and elasticity. Finally, the fibers are wound onto spools and often heat-set for stability before being used in various products.

#1- Katie Rozeboom

  Katie Rozeboom Introduction         Hello! My name is Katie Rozeboom, and I am from Schoolcraft, MI. I chose Interior Design as my major because I've always loved being creative, arranging things, and picking out colors that go together. I am interested specifically in Residential design. I have taken online courses before. I can be successful in this class if the assignments are clearly laid out and very specific about what is required. Current LEED Initiatives         The most current LEED version is LEED v5. According to the USGBC, this version's rating system and approach have significantly changed. This shift has been the largest structural reorganization of the system since v2009. Its main goal is to align the LEED rating system with current industry practices and to address today's climate crisis. The guiding principles of LEED v5 are as follows: Decarbonization: "Decarbonize the building industry swiftly to refle...

Week 14: Research Initiatives

Research Initiatives: Week 14 INT 323 Eva Serrato Carpet Tile Installation: For carpet tile installation you first have to make sure that the sub floor is in the correct condition and any sort of padding is installed beforehand. There are different patterns that need to be decided before installation starts. After this is decided then how the tiles will be planned when they intersect a doorway or a corner and this can be decided by a dry lay which is laying the carpets down before they are glued. Then the tiles need to acclimate to the humidity of the room. Then the adhesive is placed, either a peel and stick or a direct glue down. Usually starting in the middle of the room to the outside would be most efficient.  Carpet tiles can show more seams; however the installation can be easier as well as the repair can be cheaper that wall to wall because the individual tile can be removed. Wall to Wall Installation: For wall-to-wall carpet installation it is important that the subfloor is...

#1 Personal Blog/ Special Considerations- Eva Serrato

  Personal Blog/ Special Considerations INT 323   Eva Serrato   My name is Eva Serrato and I am Senior at Judson University. I am on the women's Cross county and Track team. My hometown is Gilberts IL, which is 15 minutes away from Judson. The reason why I picked interior design is because, growing up I always liked art and design because my mom was an art teacher, I was exposed to design and creating art at a young age. Over the years I wanted to pursue a career that would make me money, but also have a design aspect as well. I chose interior design because I love the design and problem-solving part of the job, I love the balance of creating and problem solving while also having fun designing and talking to clients.           My area of interest would be residential work, however, over the past couple years I have been leaning more towards commercial, specifically hospitality work. I feel that there are many interesting parts to designi...
