Textile science Chapter 2 hw 1. State the fiber property that most affects the indicated condition:
a. Pilling propensity pilling = hydrophobic & strength & static electricity
b. Producing permanent pleats. pleats = resiliency & thermoplasticity
c. Improving insulation. Scientists model the manner in which a liquid wets fibers, gaining useful insights for improving glass wool properties. Sandcastles are a prime example of how adding a small amount of liquid to a granular material changes its characteristics
d. Resistance to wear from rubbing abrasion resistance
e. Static buildup. hydrophobic fibers
f. Determination of “hand.” Hand” is the way a Fiber feels. Some terms used to describe the …show more content…
On the other hand, polyester is a manmade Fiber so you have more creativity with it. ´hey can be engineered a certain way with a specific end use. Many chemicals are involved
5. What is crimp? How does it affect the properties of a textile? Crimp is the bends and twists along the length of a fiber.
It increases resiliency, bulk, warmth, elongation, absorbency, and skin comfort. Makes the hand harsher and luster is reduced as crimp increase. Allows the fiber to stand off the skin so fabric will not cling to the wearer 's skin. Also helps make the fiber able to withstand being bent back on itself many times without breaking.
6. How does fiber absorbency affect the properties of a textile? Absorbency affects: skin comfort, static build-up, dimensional stability in water, stain removal, water repellency, and wrinkle recovery.
7. What is pilling? Why is it more apparent on some fibers than on others? Pilling is the formation of groups of short or broken fibers on the surface of a fabric that are tangled together into tiny balls (pills).
More apparent on hydrophobic fibers because their fibers have greater electrical static attraction for each other ran do not fall off the fabric surface. Wool also pills because it has a scaly surface. 8. Which fiber would be more suitable for athletic wear—one that wicks or one that absorbs moisture? Why? Wicking fibers are more suitable for athletic wear because

In this lab, three different brands of paper towel were tested to see which brand could absorb the most water. The brands that were tested were Bounty, Sparkle, and the Dutch Fork High School paper towels. To understand which paper towel would be the most absorbent one must know what makes paper towels absorbent in the first place. Studies show that, “Paper towels are made up of cellulose fibers, which also make up cotton, wood, and most other plants. These cellulose fibers are actually giant molecules that consist of many small molecules linked together. The small molecules that combine to make up cellulose are sugar molecules; that’s the key to the absorbency of paper towels.” (Brown, 2013). Other key factors that play into the absorbency
The concentrations and absorbances of the red and blue dyes were used to find the concentration of the purple dyes. From the graph of the blue dye, the linear equation for absorbance was y = mx + b. From that formula came the equation y = 7.915 x 104 (x) + 0.02489, where y represents absorbance, m is slope, x is concentration/molarity, and b is the constant/y-intercept. The same set up was performed for the red dye, but the equation produced was y = 1.045 x 104 (x) +.001298. The equations found when graphing absorbance vs. concentration were used to find the concentration of the purple dyes. The absorbance for purple dye 3 on the red wavelength of 470 nm equaled 0.149 and 0.818 for the blue wavelength of 635 nm. For purple dye 1
The ending result of this experiment confirms that as five test tubes are lined up with the varying level of absorbance, different results in the level of absorbance will appear as well, this is visible in above table. Thus, this is due to the varying amount of water in the solution. The blank sample had a 0.30 in its level of absorbance.
After reviewing the data, it can be concluded that our hypothesis was, indeed, true. Though it is difficult to confirm whether the cuvettes that contained the highest concentration (15% and 10%) denatured, our team agreed that the higher concentration was less effective due to lower change in absorbance.
(Choose a garment, which can be used to discuss fashion from the point of view of the consumer. This garment must be able to demonstrate how the consumer individually constructs their identity and conveys that identity through the style and styling of clothing. You should treat this garment as an object as a form of evidence, which can help you to explain theories of fashion discussed in the sessions. The intention of your analysis is to examine the ways in which we can ‘read’ objects and images, understand their meanings and explain them in the context of broader theoretical and social concerns. You should aim to be as analytical as possible. You may want to use further
Function: The function of this product is to reduce underarm wetness and control body odor. The deodorant aspect of this product reduces body odor by killing the odor-causing bacteria. The antiperspirant aspect of this product mitigates wetness by inhibiting gland sweat.
Lululemon prides itself on using a high quality impact fabric known as the “all moisture wicking” which is said to pull away perspiration from the physique and disperse it across the material, thereby vaporising the wetness and drying it quickly. Their fabric is made for all kind of athletic activities in all weather, and ranges from light to thicker outwear. Other innovation made on their apparel products are the design functions which allow places for
The Hmong people are well known for their survival antics from their silent war with China and their migration from the Vietnam War. Hmong is a term many have never even heard of but their culture it is known as "free people." Hmong textiles has survived just like their whole culture. The attractive handcrafted designs have been in their history for over two centuries, and their embroideries are popular among the Asian countries as well as the United States. Hmong textiles includes a variety of embroideries on their Flower cloths, story cloths, and their New Year dress. All fabrics have powerful importance in their customs to bring prosperity and good fortunes. Needlework is a substantial skill in their community that can not be forgotten,
Staying strong and committed in family matters is a big deal, especially when there are children that are being cared for. As we are all affected by human nature, it is hard to do the right thing while trying to satisfy our desires. There is also the possibility of setting expectations way too high and then ending up being disappointed in the end. That is what happened to Mrs. Sommers in “A Pair of Silk Stockings.” Mrs. Sommers longs for a former life throughout the short story and ultimately shows how selfish desires can lead to guilt and dissatisfaction.
Sweaters also have simple sewing operations, so they can be produced in an individual cell. Also the Sweatshirt style which has sewing operations similar to sweaters can be produced in the same cell.
