modal

As early as the 1980s by the Austrian Lenzing (Lenzing) company development, is the early development of a new type of regenerated cellulose fiber. Due to the high price of the fiber at that time, the performance was not fully recognized and other reasons, has not formed mass production.

Until the end of the last century, with the improvement of people's living standards, the requirements of wearing comfort have gradually increased, and the close-fitting clothes woven by Model fiber have entered the family. Just like the past lycra label, modal label has become a new favorite of this era, is welcomed by consumers.

Modal is a kind of new, high wet modulus viscose fiber is a new generation of regenerated cellulose fiber, raw materials are all natural materials, the product USES is the European beech, first it is made from wood pulp, and then processed into fibers through the special spinning process, the spinning process used by more than 99% of the solvent can be recycled, in the whole process and basic no pollution, is harmless to human body, And can decompose naturally, harmless to the environment, is known as green environmental protection fiber.

Fiber properties

1 Physical Properties

Modal fiber has a long length, so that modal fiber has better yarn strength and uniformity, and less hairiness, smooth surface. Modal fiber has better thinness than ordinary viscose fiber and can be spun into finer yarns. Modal fiber density is greater than ordinary viscose fiber, water volume expansion rate is smaller than viscose fiber, modal fiber is less affected by humidity than viscose fiber.

2 Mechanical Properties

Compared with viscose fiber, modal fiber's dry strength and wet strength, dry initial modulus and wet initial modulus are larger, while the dry elongation and wet elongation are smaller, and all kinds of properties are less affected by humidity than viscose fiber.

Modal fiber has better dry and wet strength than rayon fiber, and its high strength makes it suitable for microfiber production. At the same time, the degree of fibrification is small, which makes it have good spinnability and weaving property.

3 Feel and luster

The good appearance of Modal fiber gives its fabric a silky luster, which greatly elevates the grade of clothing. Mixing modal fiber with cotton fiber will produce a luster similar to that of the cotton silk process; Modal fiber fabric color is bright and bright; It is a natural mercerized fabric.

Modal fiber is fully fine denier, its longitudinal section structure is smooth, so that it has a silk-like soft and lubrication, the feel of the fabric is particularly smooth, and you can feel its soft and smooth contact with the skin. Good hand feel and drape, make the clothing appear more elegant, soft tactility gives woven products a good name of second skin.

4 Dyeing properties

Dyeing mainly occurred in the amorphous region of fiber molecular structure, which was related to the degree of crystallinity of fiber molecular. Modal fiber has good dyeing properties, thorough color absorption, good color fastness, bright and bright fabric color, as a cellulose fiber, similar to viscose fiber, cotton fiber dyeing properties. Traditional dyes used for cellulose fiber dyeing, such as direct dyes, reactive dyes, VAT dyes, sulfide dyes and azo dyes can be used for modal fabric dyeing, and the same dyeing rate, modal fabric color is better, bright and bright. Modal and cotton blending can be mercerized, and dyeing uniform, rich and brilliant, color and luster maintain.

5 blending properties

Modal fiber spinning can produce a more uniform yarn, and other fibers can be mixed in different proportions, such as wool, cotton, hemp, silk, polyester, etc., can get high-quality yarn. Modal fiber dry strength is close to polyester, wet strength is much better than ordinary viscose, gloss, softness, hygroscopic, dyeing, dyeing fastness are better than pure cotton products; With it made of fabric, showed a silk gloss, has a pleasant soft touch feeling and drape and excellent wear resistance, Modal fiber can be mixed with a variety of fibers, interwoven, such as cotton, hemp, silk, to improve the quality of these fabrics, so that the fabric can keep soft, smooth, play their own characteristics of fiber.

6 Stable performance

Modal fiber fabrics take stable performance, clothing effect is good, shape stability is strong, with natural wrinkle resistance and permanent, make wearing more convenient and natural. After the test comparison, and cotton fabric after 25 times of washing, cotton fabric feel will be more and more hard, and Modal fiber fabric is on the contrary, the more soft, the more beautiful wash.

The development and utilization of modal fiber caters to people's desire to "return to nature" and use natural fiber. Modal fiber dry strength is close to polyester, wet strength is much better than ordinary viscose, gloss, softness, hygroscopic, dyeing, dyeing fastness are better than pure cotton products; The fabric made of it exhibits a silky sheen, pleasant soft touch and drape, and excellent wear resistance.

Modal is increasingly used as a material for outerwear and decorative fabrics. In order to improve the poor crisp of pure Modal products, Modal can be blended with other fibers, and can achieve good results. Modal can also be woven in the process of weaving, and can be interwoven with other fiber yarns, thus woven into a variety of fabrics.
