To answer your question, wool and silk will dissolve in chlorine bleach.

An example of a medicine that is commonly used to cause color loss is benzoperoxide.

The most important components of tufted carpets are the ANSWER face yarn, the primary and secondary backing, and the latex.

How is the vacuum monitored effectively throughout the process of hot water extraction? ANSWER recovery, inches per lift, and cubic feet per minute

The major role of fluorochemicals is to resist soil, oils, and water-based substances. Fluorochemicals increase what that substance is.

Tannin is the term that is used to describe stains caused by coffee or tea.

The size of a micron is what? "Millionth of a meter" is equivalent to "ten-thousandths of an inch."

What is the process of making fusion-bonded carpets? The answer is that fuzed face yarn is fuzed into the backing.

Lower pH and faster drying are the answers to the question of how to reduce wicking in the carpet.

For the celery burn test, the answer is nylon

The charred test: acrylic is the answer to the burnt meat

what percentage of dry soil is included within the carpet? - The answer is 79

respond to the following: chemical, heat, agitation, and time

what causes spots to develop again and again? ANSWER residues that are left behind

the changes that occur when indicator dyes are present - the answer is ph

In the fifth generation of nylon, what prevents the dye blockers from working? The answer is catanionic detergents that are positive.

In what ways can heat affect cleaning? - ANSWER increases the rate of energy

solution dying is the way of dyeing that is considered to be the most persistent.

whether the drying process is aided or hindered by the following factors: temperature, humidity, air flow

The answer to the question "which fiber absorbs the least amount of moisture" is: "olefin"

To answer your question, polyester is the fabric that emits an orange flame, sputters, and stinks.

synthetics and plastics are the kind of fibers that exhibit melting rather than burning.

The answer to the question of what causes browning is a lengthy drying time.

When it comes to drying, what exactly is wicking? ANSWER: the upward flow of moisture

faulty formulation of latex is the most common cause of delamination, according to the answer.

The answer to the question "what man-made fiber floats on water and why" is olefan.

acrylic is the best example of a man-made fiber that is similar to wool.

ph that is advised for wool - this is not one of them

the answer is jute Up until 1985, weft threads were used in the manufacture of axminister carpets and other woven items.

Natural fibers have something in common with one another (protein and cellulose), and when they are burned, they produce a crumbly ash.

Raw materials that are based on coal or petroleum are the most frequent raw sources for synthetic fibers. comparable to plastic

nylon is the most often answer answer. it is possible for acid dye stains to discolor when exposed to oxidizers and dissolve in formic acid.

The first generation of nylon; ANSWER circular clear fiber

ANSWER produced in varied forms such as square or trilobal, with improved soil and abrasion hiding capabilities, is the second generation of nylon.

ANSWER introduced an anti-static core to the fiber of the third generation of nylon in order to assist in the reduction of static electricity.

Answer: the use of fluorochemicals to four-generation nylon helps to increase the material's resistance to soiling

The fifth generation of acide dye resisters that are less than 10 ph

acrylic - the ANSWER mixed with wool, produced at a high cost, took on the appearance of wool after being crimped

polyester is a fiber that resembles nylon but is less expensive. It can be used as either continuous or staple filament.

The answer is that polypropylene and olefin are impermeable to water; greasy stains are drawn to it; it is susceptible to friction burns; and it is susceptible to crushing matting.

ph - ANSWER 0-14, 7 is neutral, 8 is ten times more intense than 7, etc.

oxidizers - the correction There is some potential for sodium perborate and hydrogen peroxide to be utilized as gentle bleaching agents. adding oxygen
