of fabric, cut them into 20 by 20 cm squares and label them. We had to buy some dye in order to find out how each fabric reacted to it. We used three squares of each of out five fabrics, our fabrics were cotton, linen, poly cotton, polyester, and nylon. Then you had to wash them in the washing machine for approximately thirty- eight minutes, with one fourth cup of Tide Simply fresh and Clean detergent, Then the materials dried over night, for the best results. The next day we put them in a sixteen
While performing the slime lab, we were trying to find the effect of borax on glue and water. We mixed glue and water together and added small amounts of borax water to it. We wanted to find the difference in stretchiness with different amounts of borax. After adding the borax, we measured how far the slime could stretch. We hypothesized that the slime would stretch farther when more borax was added. Slime was developed in the beginning of the twentieth century during the time while synthetic
Nylon 66 is a type of polyamide or nylon. It is most commonly found in fishing nets, ropes, cords and fishing line making it the camping and leisure material of the century. It is made up of two monomers which each containing 6 carbon atoms, hexamethylenediamne and adipic acid (figure 1.), which give nylon 66 its name. This specific type of nylon was invented by Wallace Carothers at DuPont’s research facility on the 28th of February, 1935. Properties of this polymer that make it the best
This single strand of nylon was to be analysed at Georgia State Crime Laboratory by Larry Peterson a microanalyst. He found that this nylon strand was very similar to those of the earlier nylons found on the clothing of his victims. They found it was yellow-green in colour but what was more important for the analysists was that the cross-section of the fibres all had the characteristic of being a fibre used in furnishing or carpet. This helped to narrow down the origin of the fibre and with the suspicious
E. Discussion: In order to synthesize the polymer, Nylon 6,10, we had to complete a few steps to create the chemical reaction that combined sebacoyl chloride and hexamethylenediamine. First we measured the mass of the two graduated cylinders when they were empty, and measured it again after they were filled with sebacoyl chloride and hexamethylenediamine. We did this in order to find the measurements of the reactants. When we measured the graduated cylinder when they were emptied, one weighed at
The presence of a suture in a surgical wound has been found to increase the tissue's susceptibility to infection.(10) (3) Occurrence of bacteria inside a wound does not always implicate an infection. Altemir and Culbert(29) have suggested that the infection risk depends upon the host resistance, bacterial contamination and virulence of the organism. In human volunteers, Elek and Conen(3) have noted that an injection of 106 Staphylococcus pyogenes was required to elicit a pus-forming clinical infection
with Locator abutment. Six blocks for each group were used as prosthetic blocks, which included the overdenture attachment to be studied. Prosthetic blocks for Group A contained nylon cap - clear attachments, Group B contained nylon cap - pink attachments, Group C

synthesis of Nylon-6,6 Oxidation of cyclohexanol: Adipic acid Student’s Name: Nico John McQuiston Lab partner’s name: Christine Sullivan Instructor’s & TA’s name: Dr. Behnoush Memari Date Of Experiment: 9/18/2014 Abstract The purpose of this experiment was to prepare nylon-6,6 utilizing step-growth polymerization. It was hypothesized that the combination of Thionyl chloride, adipic acid and cyclohexanone would yield a chemical reaction which would produce of nylon-6,6. Nitric
As shown in Table 1, Glyptal was a brittle product with some viscous liquid. In the second part of the experiment, the polyamide Nylon-6,6 was produced. There are two processes used to create high molecular weight polymers, step-growth and chain-growth. These two categories of polymerization can be used to produce nylons. Step-growth and chain-growth both begin with monomers which combine to form oligomers and then polymers. Unlike step-growth, the monomers in chain-growth
Hair and fiber analysis was still an unfamiliar idea at this time, and it was not well received in trials. Additionally, identifying the potential source of these nylon fibers in a yellowish-green color was the main issue. In the Atlanta metropolitan area, corpses found in waterways were either nude or just wearing underwear. After the fibers were discovered, in Atlanta, under and at both ends of the James Jackson
Introduction Chevron Phillips Chemical Company is the major producer of Cyclohexane. This successful company hoses the three largest cyclohexane plants in the world. Many are puzzled by how the production of cyclohexane seems to have become stagnant. Perhaps this is due to the cost of benzene increasing or the demand increasing. Through thorough investigation, the answer to this question and many more can be answered. There are two methods of obtaining cyclohexane. These two methods are fractional
DYEING Dyes are coloring materials used in dyeing textiles. Other hand it can be defined as a substance which may be natural or synthetic use to change or add color to the textile materials. They are incorporated into the fiber by chemical reaction, absorption, or dispersion. Dyes differ in their resistance to sunlight, perspiration, washing, gas, alkalizes, and other agents; their affinity for different fibers; their reaction to cleaning agents and methods; and their solubility and method of application
on its face, I think the idea would work in tying it in with finals- something like “Facing Finals.” She could highlight the best products for trouble spots and also the best concealers.

Starlet Styling: Movie Look of the Week Most of the beauty tutorials I’ve seen are based on popular celebrity red carpet looks, but I think it would be ideal if we pushed Mariale to do a Throwback Thursday movie makeup tutorial. She could
The Swimmer Nature. “The phenomena of the physical world collectively, including plants, animals, the landscape, and other features and products of the earth, as opposed to humans or human creations.” That defi-nition sets up two contrasts that are central in The Swimmer by S.J. Butler: man vs. nature. In order to explain how the two perform side by side in this short story, I will analyze setting and the devel-opment in the protagonist of the story as well as symbolism of a few somethings. The
pumps were paired with a skirts where a perfect outfit for the 1930s. And under the shoes most women wore nylon; they where very popular at this time. Nylons where the staple to many women’s wardrobe in the 1930s. nylons provided a lot purpose for women. They added a pop of color to an outfit, allowed women to wear shorter skirts or dresses and provided an extra amount of warmth. Alongside the nylons, gloves where also an important accessory to an outfit. They where very popular for evening dresses and
tissue (Lewis, 2013). The various utilization of this 3D bone printing technology portrays the impact that it will have on advancing medical treatment options. One of the current 3D printers is able to print at high speeds using a specific type of nylon, which has been found to be well tolerated by the human body and stronger and more durable than bone (Staff, 2013). The surgeon can take this new 3D printed bone, that is specific to the patient, and replace it within a few hours (Staff, 2013). This
This quote in the Pigman is referring Nortons eyes to a mean mouse, so the character Loraine thinks Norton’s eyes looks like a mean mouse, meaning that he is probably really mean. “. . . and her nylons do make this scraaaaaaatchy sound. . .” This quote explains how Miss Reillens Nylons sound. Her nylons
up? That is an example of static electricity. Static electricity has different strengths at different distances from the different objects you are testing. The strengths depending on what surface you use to rub against the balloon if its either nylon, fleece, or rayon. Static electricity is a neat phenomenon, because it could evolve into a way to harness this energy, it could lead to much more energy to power a Static
Very coordinated and accent outfits were a feature of 1920 's women’s fashion. This fashion included: Shoes, stockings, handbags, dresses, and hats. they all came together to make a perfect elegant style.(1920-30.com, 2012). The most popular shoes for women that were used during the 1920s were: T-strap(T-bar), Mary Jane, Oxford, and Pumps. T-Straps also known as ‘’t-bar’’, and ‘’school sandal.’’ T-strap is a shoe with two or more straps forming into one or more T-straps (Rose Clare, 1989). They
