1. Pure cotton
Pure cotton fabric is a fabric produced by textile technology with cotton as raw material. It has the characteristics of moisture absorption, warmth, heat resistance, alkali resistance and hygiene. Generally speaking, pure cotton fabric has better moisture absorption and heat resistance, and it is comfortable to wear.
Hygroscopicity
Cotton fiber has good hygroscopicity. Under normal circumstances, the fiber can absorb moisture from the surrounding atmosphere, and its moisture content is 8-10%, so it touches human skin and makes people feel soft and not stiff. If the humidity of the cotton cloth increases and the surrounding temperature is higher, all the moisture contained in the fiber will evaporate, so that the fabric can maintain a water balance and make people feel comfortable.
Warmth retention
Because cotton fiber is a poor conductor of heat and electricity, the thermal conductivity is extremely low, and because cotton fiber itself has the advantages of porosity and high elasticity, a large amount of air can accumulate between the fibers, and air is a poor conductor of heat and electricity, so pure Cotton fiber textiles have good warmth retention. Wearing pure cotton clothing makes people feel warm.
Heat resistance
Pure cotton fabric has good heat resistance. When the temperature is below 110°C, it will only cause the moisture on the fabric to evaporate and will not damage the fiber. Improved washability and wearability of pure cotton fabrics.
Alkali resistance
Cotton fiber has greater resistance to alkali. The cotton fiber will not be damaged in the alkali solution. This performance is conducive to the washing of pollution after consumption, disinfection and removal of impurities, and it can also dye, print and print pure cotton textiles. Various processes are used to produce more new varieties of cotton weaving.
Hygiene
Cotton fiber is a natural fiber, its main component is cellulose, there are a small amount of waxy substances, nitrogenous substances and pectin. The pure cotton fabric has been tested and practiced in many ways, and the fabric has no irritation or negative effect in contact with the skin. It is beneficial and harmless to the human body when worn for a long time, and has good hygienic properties.
2. Polyester-cotton blended fabric
Polyester-cotton blending is actually a fabric made of a blend of polyester and cotton. It is a variety of fabrics woven from polyester staple fiber and cotton fiber blended yarn. This fabric is usually made of 60% Five to sixty-seven percent polyester is mixed with 33 to 35 percent cotton.
The elasticity and wear resistance of the fabric are very good, the size of the fabric is stable, and the shrinkage rate is very small. The fabric made from it is generally tall and straight, not easy to wrinkle, easy to clean, and easy to dry. The smoothness and tearing strength are relatively good, not easy to wrinkle, but easy to fluff and pilling, easy to generate static electricity.
3. Viscose fiber
Cellulose fiber obtained by extracting and reshaping fiber molecules from natural wood cellulose.
The basic composition of viscose fiber is cellulose (C6H10O5). The cross-section of ordinary viscose fiber has a zigzag-shaped skin-core structure, and the longitudinal direction is straight and there are grooves. The fiber-rich structure without skin core has a circular cross-section.
Viscose fiber has good moisture absorption. Under normal atmospheric conditions, the moisture regain rate is about 13%. After absorbing moisture, it expands significantly, and the diameter increases by up to 50%, so the fabric feels hard and has a large shrinkage rate after being put into the water.
The chemical composition of viscose fiber is similar to cotton, so it is more resistant to alkali but not acid, but it is inferior to cotton in alkali and acid resistance. Rich fiber has good alkali resistance and acid resistance. Similarly, the dyeability of viscose fiber is similar to cotton, the dyeing chromatogram is complete, and the dyeing performance is good. In addition, the thermal properties of viscose fiber are similar to cotton, and the density is close to that of cotton, which is 1.50~1.52g/cm3.
The hydroxyl groups of the cellulose macromolecules are prone to various chemical reactions. Therefore, the viscose fiber can be modified by grafting and other methods to improve the performance of the viscose fiber and produce various special-purpose fibers.
Ordinary viscose fiber has good hygroscopicity, is easy to dye, is not easy to generate static electricity, and has good spinnability. Short fibers can be spun purely or blended with other textile fibers. The fabric is soft, smooth, good in air permeability, comfortable to wear, bright in color after dyeing, and good in color fastness. It is suitable for making underwear, outerwear and various decorative articles. Filament fabrics are light and thin, and can be used for weaving quilts and decorative fabrics in addition to being suitable for clothing. The disadvantages of this type of viscose fiber are poor fastness, low wet modulus, high shrinkage rate and easy deformation, poor elasticity and wear resistance.
4. Polyester
Polyester is a fiber-forming polymer made from polyterephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (MEG) through esterification or transesterification and polycondensation reactions-- Polyethylene terephthalate (PET), a fiber made by spinning and post-processing.
(1) Polyester fabric has high strength and elastic recovery ability, so it is durable, wrinkle-resistant and non-ironing.
(2) Polyester fabric has poor hygroscopicity, and it feels stuffy in summer. At the same time, it is easy to be charged with static electricity in winter, which affects comfort. However, it is very easy to dry after washing, and the wet strength hardly drops, does not deform, and has good wash and wear properties.
(3) Polyester is the best heat-resistant fabric among synthetic fabrics. It is thermoplastic and can be made into pleated skirts with long-lasting pleated skirts.
(4) The light fastness of polyester fabric is better, except that it is worse than acrylic fiber, its light fastness is better than natural fiber fabric. Especially the light fastness behind the glass is very good, almost on par with acrylic fiber.
Polyester fabric has good resistance to various chemicals. Acids and alkalis do not damage them much, and they are not afraid of molds and insects.
5. Polyester fiber
Polyester fiber fabric is a synthetic fiber obtained by spinning polyester formed by polycondensation of organic dibasic acid and dihydric alcohol.
(1) Heat insulation. Polyester fiber sunshine fabric has good heat insulation performance that other fabrics do not have, which greatly reduces the utilization rate of indoor air conditioning.
(2) UV protection. Polyester sun fabric can withstand up to 95% of ultraviolet rays.
(3) Moisture-proof. Bacteria cannot multiply, and the fabric will not be mildewed.
(4) Easy to clean. Can be placed in clean water for scrubbing.
(5) Tear resistance. No need for reinforcement, natural tear resistance, significant wind resistance and withstand frequent use.
