How Is Cotton Womern Into Cloth?


Cotton
The long cotton fibers are spun into strong treads which are then woven into cloth.

Many of the towels, sheets, shirts and clothing we enjoy using and wearing are made of cotton.  The cotton plant at harvest time looks like it has a cluster of flurry snowballs made of silky white cotton fibers.

After the cotton has been picked it is carried to a machine called a “gin” which separates the fibers from the seeds.

When the cotton arrives at the textile mill, spinning machines spin and twin the loose fibers into strong threads and wind them on bobbins for weaving.

After the thread has been spun, a machine called a “loom” automatically weaves hundreds of threads into cloth in much the same way we might weave a reed basket.

After the cloth has been woven it goes through many other steps in which it is bleached, dyed, and printed.

Chemicals are added to printed cloth to make sure that the colors remain bright. – Dick Rogers

What is pollen?


Pollen
The tiny yellow grains that are found in flowers are pollen.  The flowers use it in making the seeds that will grow into new plants.  

Plants make the pollen in the saclike anothers of their flowers.  Pollen grains are so small that they look like tiny specks.

If you look through a microscope, you can see that pollen has different shapes in different kinds of plants.  Some pollen grains are smooth and other kinds of pollen are covered with knobs and spines.  Before a seed can form, a flower must be pollinated.  This means that a pollen grain must fall on another part of the flower called stigma.

When a pollen grain of the same kind of flower catches on the sticky surface of the stigma, the pollen grains sends out a tiny threadlike tube.  The tube grows down to tiny egg cell inside the seed case.  Now the eggs are fertilized and will become a seed. – Dick Rogers
