Different types of cotton fiber | carbohydrate cotton | AM cotton | PL cotton



AM Cotton:

When cotton is treated with 2-amino ethyl sulphuric acid in NaOH, AM cotton is produced without changing its structure. Dyed AM cotton has better resistance to light and washing.

Carboxymethylated (CM) cotton):

Cotton treated with manochloro acetic acid and then NaOH is converted into CM cotton. There are two types of CM cotton and can accept crease resisting treatments with greater effect. The second form of CM cotton can be produced easily in mercerizing equipment at very low cost. The product can be crease proofed with particularly good effect.


Cayanoethylated (CN) Cotton:

Treatment of cotton with acrylonitrile yields chemically modified cotton described as cayanoethylated (CN) cotton. Though this looks and feel like ordinary cotton and many of its properties are similar to that type of cotton, but CN cotton has extremely good resistance to rotting influences. it has better resistance to the effect of heat than ordinary cotton. CN cotton dyes more readily than ordinary cotton with certain types of dyes.


Pripiolactone (P.L) Cotton:

Treatments with propiolactions converts cotton into a modified cotton described as PL cotton. How is organic cotton grown? Farmers use natural compost or manure in the place of chemicals. Harmful pesticides are replaced with organic friendly ladybugs. Instead of spraying chemicals on the cotton during harvest the fields are flooded to defoliate the plants.
Any machinery used for harvesting cotton must be continually cleaned and sterilized. Any knitting machines. That producers use must also be separate from other machinery. This prevents any other fibers of non organic crops from being combined with the organic cotton.

Transition cotton:

Organic cotton must be grown in fields that have been free of synthetic pesticides and fertilizers for three years. As farmers switch over to and use organic farming methods the cotton grown during this three year period is called transition cotton.

Wall-mart has been purchasing millions of pounds of transition cotton. This has greatly help farmers to make the transition to organic farming methods.



Green cotton:

Green, or natural, cotton is not organic.
When you see cotton products labeled “natural” you are getting conventional cotton grown with large inputs of chemicals, pesticides, and herbicides to control weed growth. The only difference between green and conventional cottons, is in the processing final product is not supposed to be treated with formaldehyde or chlorine bleach. Currently there are no federal inspection guidelines to ensure procession of green, or natural cotton, is chemical-free. It is important to understand this distinction when shopping for cotton products. Remember “Natural” and “Organic” are not at all the same.      

Transgenic cotton
Transgenic cotton, genetically engineered cotton, carries its insecticide within the plant tissues.

Types of Yarn twist | different types of yarn twist | S twist | Z twist

Types of Yarn twist different types of yarn twist S twist Z twist“S” TWIST: A single yarn has “S” twist if when it is held in the vertical direction , the fibers inclined to the conform in direction of slope of the contact portion of the letter “S”. axis of the yarn “Z” TWIST. A single has “Z” twist if when it is held in the vertical direction, the fibers inclined to the yarn axis conform in the direction of the slope to the central portion of the letter “Z”. DIRECTION OF TWIST: In the designation of yarns, it is essential to specify the direction of twist. Besides its importance in simplifying the trade, it is of great technical importance in designing fabrics. For example, in a twill fabric, the direction of twist in the yarn is of particular importance in determining the predominance of twill effect. For a   right-handed twill, the best contrasting effect will be obtained when a yarn with Z twist is used; on the other-hand a left-handed twist will produce a fabric ha...

macro-structure of cotton fiber | Under a microscope cotton

Under a microscope a cotton fiber appears as a very fine, regular fiber, looking like a twisted ribbon or a collapsed and twisted tube. These twists are called convolutions there are about sixty convolutions per centimeter. The convolutions give cotton an uneven fiber surface, which increases inter-fiber friction and enables fine cotton, yearns of squatted strength to be spun. The appearance of the cotton fiber’s cross sections is referred as being kidney-shaped. The micro structure of cotton The cotton fiber is a single plant cell. Its cross-section is oval, compared with the normal hexagonal plant cell. Cotton has a district cuticle, well developed primary and secondary walls and a lumen. Layer 1 the cuticle is a waxy protective layer that provides water resistance to the fibers as they are growing. This lawyer is removed by scouring during processing before spinning.

Definition of yarn | different types of yarn | class of yarn

A.         CABLED YARN :- These type of yarn are made by twisting together two or more multi folded plied yarns. In general, it is constructed by twisting the plied yarns around each other successively in the opposite direction the preceding twist, i.e. S/Z/S or Z/S/Z. As a result, the opposite twist direction cause the plies to grip each other and maintain adherence. These yarns are hard, rough and strong Example CORDS.   B.         SINGLE YARN :- It is the simplest continuous strand of textile material composed of the following:- i)                     Continuous Filament:- These type of yarn are simplest in structures but they can be subjected to different modifying processes to change their extensibility and other properties. They are of the following types: 1) Mono filament which contains only ONE filamen...
