How to distinguish between Rayon and Cotton?

What is Rayon?

           

                     

Rayon is the common name of viscose fiber. Viscose fiber is the alpha-cellulose extracted from wood and plant ligustrum and other cellulosic raw materials, or cotton staple as raw material, processed into spinning stock, and then made by wet spinning man-made fibers.

                               

                              

Rayon Characteristics

                                   

                             

Rayon is characterized by good dyeability, brightness and fastness, comfortable to wear, resistance to dilute alkali, moisture absorption and cotton close. The disadvantage is that it is not acid-resistant, poor resilience and fatigue resistance, and low wet mechanical strength. It can be purely spun or blended with polyester and other chemical fibers.

                                                       

                                                           

                                       

                   

What is 100% Cotton?

                     

                               

Cotton fabric is cotton as raw material, through the loom, by the warp and weft yarn longitudinal and horizontal sinking interwoven textiles. At present, according to the actual processing of cotton sources and distinguished as primary cotton fabrics and recycled cotton fabrics.

                                        

                              

                             

                                   

100% Cotton Characteristics

                     

           

(1) Cotton fiber residence has good moisture absorption: in general, cotton fibers can absorb moisture from the surrounding atmosphere, its moisture content in 8% --- 10%, so when the human skin contact, feel soft and comfortable. If the humidity of the cotton fiber increases, and the surrounding temperature is high, all the moisture of the cotton fiber will evaporate. So that the cotton fabric to maintain a horizontal state, the same make people feel comfortable.

(2) Cotton fabric heat resistance is good: at the same time, at 110 Celsius a little, will only cause the evaporation of moisture on the fabric, will not damage the fiber, so cotton fiber at room temperature using room temperature, washing, etc. on the fabric will not have an impact. In this regard, its heat resistance also improves the durability and washability of cotton fabrics.

(3) Cotton fiber resistance to alkali is strong: in the alkali solution, cotton fibers will not damage the phenomenon, in response to the cotton fiber alkali resistance. Therefore it is conducive to the use of pollution after the washing as well as disinfection of impurities.

                          

                    

Difference: Rayon and 100% Cotton method

                 

                   

The appearance of man-made cotton cloth is extremely similar to cotton, and its method of differentiation is mainly from the following points:

           

           

Smoothness: man-made cotton, smooth surface, very few yarn defects, no impurities, fine and smooth; while the surface of cotton can see cotton shells, impurities, etc., the smoothness is not as good as man-made cotton;

         

           

Yarn uniformity: man-made cotton fabric yarn count stem uniform, few defects; while cotton fabric yarn count stem less uniform than man-made cotton, especially in the thick cloth more obvious;

                       

                 

Feel: rayon, regardless of the thickness of the fabric, feel mostly soft, while cotton is slightly coarse and hard feeling;

                 

               

Color: rayon luster and color are good, compared with cotton, rayon is more vivid and beautiful;

                               

               

Creasing: rayon is easy to crease, when the hand clutch a handful of cloth, spread, there are many creases, but also not easy to recover in time, cotton, although there are creases, but lighter than rayon;

                           

                     

Drape: man-made cotton drape is better, cotton drape is not as good as man-made cotton;

                         

                   

Strength: man-made cotton fabric strength is low, not as strong as cotton, especially in a humid environment, man-made cotton fastness is poor, when compared with the draw from the side of the cloth, stretching, man-made cotton than cotton silk easy to break, therefore, most of the man-made cotton texture is thicker, no cotton linen yarn as thin and light.
