Fusible felt is usually thinner than most interlining materials. When you iron the outside fabric on the fusible felt it literally fuses together. Do NOT iron the fusible felt directly, it will melt. Interlining is usually loose between stitching whereas if you iron both the top and bottom outer linings with the fusible felt in the inside both outer linings will become attached.
Side note: I am no expert I may be mistaken with the information I've provided. Mostly, I answered the question on intuition. I myself just heard of fusible felt yesterday. :D

Difference between astm d-226 and d-4869?
Different types of asphalt felt have different weights. Here are some data on the weight of felt types per 100 square feet: Weight per 100 square feet: Unrated (non-ASTM) #15 felt: 7.6 to 8.8 lbs. ASTM D 4869 #15 felt: 8.0 to 9.7 lbs. ASTM D 226 #15 (Type 1): 11.5 to 12. 5 lbs. Unrated (non-ASTM) #30 felt: 15.7 to 19.9 lbs. ASTM D 226 #30 (Type 2) felt: 26.4 to 27.3 lbs. Other relevant information from the article: "Asphalt felt, which has been around for over a hundred years, was originally a true cloth felt. "A long time ago, they used rag felt, which was cotton," says Dodie Webster, technical services manager at Tamko Roofing in Joplin, Mo., a manufacturer of asphalt felt. "But we can't get cotton rags any more." Since present-day asphalt felt is a paper product, the term "felt" is somewhat of a misnomer. "Unsaturated felt is basically composed of recycled corrugated papers mixed with sawdust," Webster says. Over the years, asphalt felt has also gotten lighter. "In the old days, it used to weigh 15 pounds per 100 square feet, but not anymore," says Allen Snyder, product engineer at CertainTeed, a manufacturer of asphalt felt. The main reason manufacturers make light-weight felts is because they're cheaper. "The whole issue comes down to price," says Ed Todd, technical manager at Atlas Roofing, an asphalt felt manufacturer in Atlanta. "This is a price-sensitive product," Todd says. Manufacturers now call their product "number 15" felt instead of 15-pound felt, and it weighs anywhere from 7 to 14 pounds per square. "ASTM has established two standards for asphalt felt. The less stringent standard is ASTM D 4869, which requires Type 1 (#15) felt to weigh at least 8 pounds per 100 square feet. The more rigorous standard, ASTM D 226, requires a minimum weight of 11.5 pounds per square. Most lumberyards stock only light-weight asphalt felt with no ASTM rating. "We sell a lot of the lightweight felts, the non-ASTM #15," says Webster. "It is probably our biggest seller." This type of #15 felt sometimes weighs only 7.6 pounds per square. There are a few regions where ASTM-rated felt is widely available, however, because of code requirements. "The most stringent felt market in the U.S. is Florida," says Ed Todd, of Atlas Roofing. "In Florida, at a minimum you must have 'ASTM D 4869' on the wrappers." "Asphalt felt is also available in a heavier version, commonly called 30-pound felt. This #30 felt is available in both the unrated grades and the ASTM-rated felts. ASTM standards refer to #30 felt as Type 2. The lightest unrated #30 asphalt felt is still heavier than the heaviest ASTM-rated #15 felt, making it a logical choice for concerned builders. "Asphalt felt has a permeance of only 5 perms when dry, but a much higher rating of 60 perms when wet. Fans of felt note one of its advantages over housewrap: If water gets behind felt - either due to a flashing leak or condensation from solar-driven moisture - the felt can soak up the liquid water and gradually dry to the exterior."
Is laminate flooring better with or with out backing?
It really makes no difference, except that some form of underlayment or backing is necessary to a successful installation. The existence of a backing already applied to the laminate makes no difference as to the quality of the flooring. But floors installed with no backing or foam or felt underlayment are prone to cracking and splitting, and are very noisy underfoot.

A pulse deficit is the difference between an actual heart beat and the pulse felt in the wrist or neck. Normal pulse deficits can be felt in someone with a pacemaker.
Why is the difference between the durations of day and night hardly felt at kanniyakumari but not so in kasmir?
The mainland of India extends between latitudes 8*4'(Kanyakumari)and36*6'N(Kashmir).The latitudinal extend influences the duration of day and night as one moves from south to North.Hence the difference between the duration of day and night hardly felt in Kanyakumari but not so in Kashmir.

Why is the difference between day and night hardly felt in kanyakumari and not in kashmir?
Kanyakumari is just 8 degrees away from the equator. As equator receives the direct Sun rays, there won't be hardly any difference between the day & night. Where as, Kashmir is 37 degrees away from the equator. So there can be about 5 hrs difference between day & night.
Why is the difference between durations of day and night hardly felt at kanyakumari but not so in kashmir?
The latitudinal extent influences the duration of the day and night, as one moves from South to North. As Kanyakumari lies close to the equator, the sun rays are felt more whereas Kashmir lies above the tropic of cancer, therefore sun rays are felt slanting towards the north of equator so the difference is felt more in kanyakumari than kashmir.
