polyester fiber

Part.2

1. Short fiber:

It can be spun purely, but is usually blended with cotton, wool, viscose and other fibers to improve its wearing properties.

(1) Cotton fiber

1.65~2.2dtex(1.5~2.0D)×35~40mm

Mainly polyester-cotton blends, with a blending ratio of 65% to 67% polyester and 35% to 33% cotton. It can also be blended in other proportions.

High strength and low elongation type:

High strength, small elongation, good spinnability of cotton, high quality index of spun yarn, crisp, smooth and good shape retention of the fabric. It is mainly used for blending with cotton. Depending on the specifications, it can be spun into various light and smooth clothing materials. , high-strength knitting yarn, sewing thread, etc.

Low strength and high stretch type:

The fabric has good dyeability, soft hand feel, abrasion resistance, impact resistance, not easy to pilling, good wearing performance, but low strength and many yarn breakages. It is mainly used for blending with wool and viscose.

(2) Medium and long type

2.2~3.3dtex(2~3D)×51~76mm

It is mainly used for blending with wool-type viscose fiber. The blending ratio is roughly the same as the cotton-polyester blending ratio. In order to reduce the price of finished products and fabrics, viscose fiber can be increased to 50%. Fabrics used for sewing outerwear, casual clothes, shirts, skirts, sportswear, etc.

(3) Hair type

2.75~4.4dtex(2.5~4D)×35~40mm

Mainly used for blending with wool. The blending ratio is: polyester 45%~55%, wool 55%~45%. The fabric is mainly used for sewing outerwear. In addition to the above uses, polyester short fiber can also be combined with other natural fibers and natural fibers. Blended with scraps and other fibers, it can also be blended with two other fibers to prepare a three-in-one fabric. With the development of new varieties, some of the shortcomings of polyester are being improved and its uses are broader.

2. Filament

Including pre-oriented yarn (POY) and drawn yarn (DTY), which are mainly used to process into low elasticity yarn for weaving, and can also be directly woven or knitted.

(1) Conventional silk

110~165dtex (100~150D) or above, suitable for making all kinds of wool-like fabrics and other medium-thick clothing materials

78.4~82.5dtex (68~75D) Suitable for general clothing materials

33~55dtex (30~50D) Suitable for making various thin imitation silk fabrics, underwear materials, quilt tops, decorative fabrics, etc.

(2) Special-shaped wire

The cross-section of the silk is different from the conventional circular cross-section. There is a triangular cross-section with sufficient mercerization, which is suitable for making various imitation silk fabrics; the multi-leaf cross-section has good covering properties, the fabric is soft, elastic, and has a strong sense of wool shape, so it is suitable for processing wool-like products; Hollow-shaped cross-section fibers are light, soft, have good thermal insulation properties and good resilience. They can be used to imitate down and be used as batting, batting, pillow cores, etc.

(3) Air textured yarn

The individual filaments are entangled with each other, forming a textured yarn with small loops of filaments on the surface of the yarn. This yarn not only retains the advantages of polyester such as high strength, good wear resistance, crisp fabric, easy washing and quick drying, but also overcomes the shortcomings of polyester low elasticity such as aurora, waxy feel and poor air permeability that cannot be overcome. It can be woven and knitted directly, eliminating the need for curling, cutting, packaging, and then sending to the textile factory for multiple processes such as blow cleaning, steel wire, drawing, roving, and spun yarn. The fabric produced can rival fine yarn in terms of comfort, silk-like appearance, bulkiness and covering performance. Fabrics made of imitation wool not only feel and look like pure wool fabrics, but are also of high quality and low price.

(4) Network silk (starch-free silk)

The cohesion between the monofilaments is high and the bundling properties are good. It can be directly woven or knitted, eliminating the need for twisting, sizing and other processes. Depending on the fabric, silk, Paris, gabardine, patterned tweed, etc. can be woven.

(5) Mixed fiber yarn (colorful yarn)

Utilizing the various characteristics of synthetic fibers, modified, textured, multifilament or chemical fibers with different components or different cross-sections, different shrinkage rates, and different glosses and colors are produced in the form of random, block, sheath-core, juxtaposition, etc. Mixed together or twisted togetherCharacteristics and applications

Part.8

Lyocell is a new, environmentally friendly fiber that is hailed as the “green fiber of the 21st century” by the international textile industry. Its excellent properties of natural fibers and synthetic fibers allow the product to combine the moisture absorption and breathability of cotton, the feel and luster of silk, the strength of chemical fibers, and the comfort of wool. Its great affinity with natural fibers enables the development of a variety of products. High value-added woven and knitted products have extremely broad market prospects.

Characteristics of Lyocell (Tencel short fiber, Newcell filament yarn) fiber and yarn:

1. It has excellent characteristics of cellulose fiber. Lyocell fiber fabric has a refreshing feel, good moisture absorption and breathability, and has the drape of silk. The touch can change from cotton to wool, silk, and various other feelings.

2. High strength. The dry strength of Lyocell fiber is close to that of polyester fiber, while the wet strength only decreases by 15%, which is far superior to viscose fiber.

3. Fibrillation. When Lyocell fiber is in a wet state, small fibrils are pulled out of the fiber surface under mechanical force, which can change the properties of the fabric surface. Through enzyme treatment, longer fibrils are removed and secondary fibrillation is performed to obtain a peach skin effect.

4. Good dimensional stability. Lyocell fiber fabric has low shrinkage and good washability.
