Polyester fiber is a modification of polyester theory, which improves the disadvantages of polyester such as low water content, poor breathability, poor dyeing, easy pilling and staining. It is a fiber-forming polymer, polyethylene terephthalate (PET), made from purified terephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (EG) through esterification or ester exchange and condensation reactions, which is made by spinning and post-treatment.
Advantages: bright luster, with a glittering effect, feel smooth, flat, good elasticity; wrinkle-free, good light resistance; hand pinch silk surface after release without obvious creases.
Disadvantages: luster is not soft enough, poor breathability, dyeing difficulties, poor fusibility, easy to form holes when encountering soot, sparks, etc.
Polyester is the simplest process among the three major synthetic fibers and is relatively inexpensive, making it a chemical fiber clothing fabric used very much in daily life. Its biggest advantage is that it has good wrinkle resistance and conformability, therefore, it is suitable for making jacket clothing, all kinds of luggage and tents and other outdoor products.
Advantages: high strength, super elasticity close to wool; good heat resistance, light resistance, wear resistance and good chemical resistance.
Disadvantages: poor dyeing, poor fusibility, poor moisture absorption and easy to pilling, easy to stain.
It is the fabric produced by using cotton as raw material. Generally speaking, cotton fabric has better moisture absorption and heat resistance, and it is comfortable to wear. Some work clothes of industries with high requirements of moisture absorption can choose cotton fabric for processing. For example, school uniforms in summer, etc.
Advantages: cotton fiber has better moisture absorption, higher elasticity, heat and alkali resistance, hygiene and health.
Disadvantages: easy to wrinkle, easy to shrink, easy to deform, easy to stick to the hair especially afraid of acid, when the concentrated sulfuric acid stains the cotton fabric, the cotton fabric is burned into a hole.
Nylon is a synthetic fiber, also known as "nylon", "nylon", the scientific name is polyamide fibre, that is, polyamide fiber. Since Jinzhou Chemical Fiber Factory is the first factory in China to synthesize polyamide fibre, it is named as "Nylon". It is the earliest synthetic fiber in the world, and has been widely used due to its excellent performance and abundant raw material resources.
Advantages: good strength and abrasion resistance, the top of all fibers; nylon fabric elasticity and elastic recovery is excellent.
Disadvantages: easy to deformation under small external force, so its fabric in the process of wearing easy to become wrinkled; poor ventilation and air permeability, easy to generate static electricity.
Spandex is a polyurethane-based fiber, also known as elastane because of its excellent elasticity, and is used in a large number of applications in apparel fabrics with high elasticity. Its main use lies in the manufacture of tight-fitting clothing, sportswear, body belts and shoe soles. Its varieties according to the needs of use, can be divided into warp stretch fabrics, weft stretch fabrics and warp and weft two-way stretch fabrics.
Advantages: large elongation, good conformability, and no wrinkling; the best elasticity, good light resistance, acid resistance, alkali resistance, abrasion resistance; good dyeing, and should not fade.
Disadvantages: the worst strength, poor moisture absorption; spandex is usually not used alone, but blended with other fabrics; poor heat resistance.
