#9 Eliana Johnson- Cotton Yarn

How to Make Cotton Yarn

 The process of turning plant or animal fibers into yarn has ancient origins, starting with primitive spindles around 500 BC in India, leading to the development of spinning wheels. Today, factories use automated machines for production.

The process begins with raw cotton, which may contain leaves and stems. A first machine removes a layer of cotton, sending it to a blending and cleaning machine that processes 500 kg of cotton per hour. After cleaning, the cotton is combed and aligned in parallel rows by a carding machine, which also discards short fibers.

Next, the cotton is formed into loose first-stage yarn called sliver. This sliver undergoes several stages: it's drawn out, stretched, and then further processed by a roving frame, resulting in a thinner, stronger third-stage yarn called roving. This yarn is stretched to be even thinner before being transferred from small spools to large cones using a winding machine, which knots and discards empty spools automatically.

An alternative method, air jet spinning, uses suction tubes to connect spools and minimize manual labor. The finished yarn is significantly lighter than the original sliver, and the entire process takes about 48 hours.

Turning Fleece to Yarn

emphasizing their services and facilities. Visitors can observe operations through windows in their retail store in Phillipsburg, Kansas. The process begins with shearing, where alpaca owners collect and skirt the fleece to remove debris.

After receiving the fibers, they are sorted by type and color, weighed, and graded based on fineness. The fibers are then washed using a specialized machine that avoids agitation to prevent felting, taking up to 1.5 hours for alpaca and up to 5 hours for sheep’s wool. Post-wash, the fibers are dried using air circulation.

Next, the fibers are fluffed using a picker to separate matting and are conditioned to reduce static. The dehairer removes coarse guard hair and contaminants. The carder aligns the fibers into a continuous web, which can be made into bats for quilts or rovings for yarn.

The draw frame further aligns and stretches the fibers for consistency. The spinner then processes the rovings into various yarn sizes, maintaining softness and loft. The yarn is twisted into plied forms and set under steam to finalize the texture.

Finally, the skein winder packages the yarn, and a computerized loom allows for weaving services for retail products like scarves and blankets. The entire fiber processing journey showcases a blend of manual and automated techniques to create high-quality yarn and textiles.

#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...
