 The Supima Story

  • Supima is a special and rare long staple cotton that is grown on family farms in California.
  • It is known as the world’s finest cotton.
  • It is strong a soft. The Cotton and its color last for a long time
  • It is the cotton of choice for the world’s leading designers and retailers.
  • On average it is 35% longer than regular cotton.  
  • Its length creates smother and cleaner yarns. The result of this is that the fabric is softer to the touch and more resistant to pilling.
  • Supima is 45% stronger than regular cotton.
  • This allows Designers to use fabrics that are lighter and drape beautifully.
  • Its fibers are finer than regular cotton. This means that dies soak through the fibers more which makes their color last longer.
  • Supima represents less than 1% of cotton worldwide.
  • Supima cotton was developed over 100 years ago in Arizona.
  • The name comes from Superior Puma recognizing the cotton's special qualities.

Making Rayon Fiber  

  • In This video they do an experiment where they make Rayon fibers
  • To do this they need a basic Copper Carbonate.
  • The substance forms by combining copper sulfate and backing soda.
  • Steps:

o   Take a beaker and pour about 4g of basic copper carbonate.

o   Next, they had a concentrated solution of ammonia. They use about 14ml 25% ammonia solution

o   Then you pour the ammonia solution into the copper carbonate. This forms a complex compound of copper which has a bright blue color.

o   Then pour the liquid into another beaker for the solution to become clear.

o   Now they have a copper compound complex, this solution can dissolve cotton and wool.

o   Then you slowly add wool to the copper complex solution. The wool is slightly soluble and forms a viscose.

o   This is a raw material needed for the production of artificial silk and it has become thicker.

o   Then you prepare 1 mol of sulphuric acid.

o   Then you put the copper compound in a syringe and slowly squeeze it into the Sulphuric acid and that creates the fiber. And let it sit and they will become colorless.

o   Then you can pull them out a feel them.

#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...
