MODAL

Modal was developed by the Austrian Lenzing company as early as the 1980s and is a new type of regenerated cellulose fiber developed earlier. Due to the high price of the fiber and the insufficient performance of the fiber at that time, mass production has not been formed.

Until the end of the last century, with the improvement of people's living standards, the requirements for wearing comfort also gradually increased, and underwear woven from modal fibers entered the family. Just like the Lycra label in the past, the Modal label has become the new darling of this era and is welcomed by consumers.

Modal is a new high wet modulus viscose fiber, a new generation of regenerated cellulose fiber. The raw materials of this product are all natural materials, and European beech wood is used. The silk process is processed into fibers. Since more than 99% of the solvents used in the spinning process can be recycled, there is basically no pollution in the entire production process, which is harmless to the human body, and can be decomposed naturally, and is harmless to the environment. It is called green Environmentally friendly fiber.

1.  Physical properties

Modal fiber has a longer length, so that the modal fiber has good yarn strength and evenness uniformity, and has less hairiness and a smooth surface. Compared with ordinary viscose fiber, Modal fiber has better fineness and can spin finer yarn. The density of modal fiber is greater than that of ordinary viscose fiber, and its volume expansion rate when exposed to water is smaller than that of viscose fiber, indicating that the modal fiber is less affected by humidity than viscose fiber.

2. Mechanical properties

Compared with viscose fiber, the dry strength and wet strength, dry initial modulus and wet initial modulus of modal fiber are larger, while the dry elongation and wet elongation are smaller, and various properties are affected by humidity. The impact is less than that of viscose fiber.

Modal fiber has better dry and wet strength than viscose fiber, and its high strength makes it suitable for the production of ultrafine fibers. At the same time, the degree of fibrillation is small, which makes it have better spinnability and weaving properties.

3. Feel and shine

The good appearance of modal fiber makes the fabric have a silky luster, which greatly improves the quality of clothing; mixing modal fiber and cotton fiber will produce a luster similar to cotton mercerizing technology; modal fiber fabrics are bright and bright in color; A natural mercerized fabric.

Modal fiber is fully refined, and its longitudinal section is smooth, making it silky soft and smooth, and the fabric feels particularly smooth, and you can feel its softness and smoothness in contact with the skin. Good hand feel and drape make the clothes look more elegant, and the soft touch gives the fabric the reputation of second skin.

4. Dyeing performance

Dyeing mainly occurs in the amorphous area of the fiber molecular structure, which is related to the degree of crystallinity of the fiber molecule. Modal fiber has good dyeing performance, thorough color absorption, good color fastness, and bright and bright fabric color. As a cellulose fiber, the dyeing performance is similar to that of viscose fiber and cotton fiber. Traditional dyes for dyeing cellulose fibers, such as direct dyes, reactive dyes, vat dyes, sulfur dyes and azo dyes, can be used to dye modal fabrics, and with the same dye uptake rate, modal fabrics have better color, bright and bright . Modal and cotton blending can be mercerized, and the dyeing is even, rich and bright, and the color remains long-lasting.

5. Blending performance

Modal fiber spinning can produce a more uniform evenness, and can be blended with other fibers in different proportions, such as wool, cotton, linen, silk, polyester, etc., to obtain high-quality yarns. The dry strength of modal fiber is close to that of polyester, and the wet strength is much higher than that of ordinary viscose. Its gloss, softness, moisture absorption, dyeability and color fastness are better than pure cotton products; fabrics made with it, show A silk surface luster, pleasant soft touch and drape, and excellent durability. Modal fiber can be blended and interwoven with a variety of fibers, such as cotton, linen, silk, etc., to improve the quality of these fabrics. The fabric can remain soft and smooth, and give play to the characteristics of each fiber.

6. Stable performance

Modal fiber fabric has stable wearing performance, good clothing effect, strong shape stability, natural wrinkle resistance and non-ironing properties, making it more convenient and natural to wear. Tests and comparisons show that after 25 washings with cotton fabrics, cotton fabrics will feel harder and harder, while Modal fiber fabrics are just the opposite. The more washed, the softer they are, and the more they are washed, the brighter they are.

The development and utilization of modal fiber caters to people's desire to "return to nature" and use natural fiber. The dry strength of modal fiber is close to that of polyester, and the wet strength is much higher than that of ordinary viscose. Its gloss, softness, moisture absorption, dyeability, and color fastness are all better than pure cotton products; fabrics made with it, show A silky luster, pleasant soft touch and drape, as well as excellent durability.

Modal has increasingly become a material for outer garments and their decorative cloth. In order to improve the shortcomings of poor crispness of pure modal products, modal can be blended with other fibers and achieve good results. Modal can also reflect its weaveability in the weaving process, and can also be interwoven with other fiber yarns to woven into various fabrics.
