Characteristics of modal fiber
(1) Modal has the characteristics of uniform high-strength fiber, the wet strength is about 50% of the dry strength, which is better than viscose fiber and has good spinnability and weaving. See the table for the comparison of dry and wet strength of viscose, modal and cotton:
Viscose modal cotton
Dry strength (cN/tex) 26 34 25
Wet strength (cN/tex) 15 19 29
(2) Modal fiber has a high wet modulus, and the shrinkage of its yarn is only about 65438 0%, while the boiling water shrinkage of viscose fiber yarn is as high as 6.5%.
(3) The high strength of modal fiber makes it suitable for producing superfine fiber. When spinning on ring spindle, rotor and rotor spinning machine, fine count yarn with almost no defects can be obtained, which is suitable for weaving light and thin fabrics (such as 80g/m2 ultra-thin fabrics) and heavy fabrics. The ultra-thin fabric produced has good strength, appearance, hand feeling, drape and processability, and the heavy fabric produced is heavy and not bloated.
(4) Modal fiber spinning can produce uniform evenness and can be blended with other fibers in different proportions, such as wool, cotton, hemp, silk and polyester. In order to obtain high quality yarn.
(5) Modal fiber can be processed by traditional pretreatment, bleaching and dyeing processes of cellulose fiber. Traditional dyes used for dyeing cellulose fibers, such as direct dyes, reactive dyes, vat dyes, sulfur dyes, azo dyes, etc., can all be used for dyeing modal fabrics. Under the same dye uptake, modal fabrics are better in color, bright and bright, and can be mercerized when blended with cotton, with uniform and dense dyeing and lasting color.
(6) The good appearance of modal fiber makes its fabric have silky luster, which makes it look noble and elegant, greatly improving the grade of clothing; Good hand feeling and drape make clothes more elegant and portable; The extremely soft touch gives the fabric the reputation of the second skin.
