Dragon Dance

Dragon yarn that is (Dance Dragon Yarn. ) Textile fabric or finished dragon dance cloth whose nature is polyester yarn

1. Craftsmanship

The dragon dance yarn includes multiple yarns, each of which The threads all include: unstretched yarn UDY, pre-oriented yarn POY, highly oriented yarn HOY, fully drawn yarn FDY, and drawn deformed yarn DTY. The dragon dance yarn is twisted by an electromagnetic relay. The electromagnetic relay contains : The first iron piece, the second iron piece, the control circuit, the iron core, and the coil. The control circuit controls the power on and off of the coil, so that the iron core generates a magnetic field intermittently, and the first iron piece and the second iron piece intermittently generate After being attached and separated, the dragon dance yarn passes through the gap between the first iron piece and the second iron piece, and the frequency converter is connected to the control circuit to control the frequency at which the coil is energized and de-energized.

Deformation

The yarn of this kind of dragon dance yarn is made of a variety of specific polyester threads. The color gradient of the finished product is more natural and beautiful, and the performance of the fabric is better. The combination of electromagnetic relay and frequency converter can improve production efficiency. High, the twisting effect is better, and the twist degree of dragon dance yarn can be varied, making the dragon dance yarn more varieties.

Dragon cloth

Dragon cloth, full name: cation cationicdyedpolyester. Chemical name: polybutylene terephthalate (elastic polyester), abbreviation: PBT, which is a modified polyester.

Due to the introduction of dimethyl isophthalate with polar group SO3Na into the polyester chips, it can be dyed with cationic dyes at 110 degrees, which is greatly improved. Improve the fiber’s color absorption properties. Moreover, the crystallinity is reduced, making it easier for dye molecules to penetrate, making the fiber easier to dye and increasing the color absorption rate. Hygroscopicity is also improved.

This fiber not only ensures that cationic dyeing is easy, but also increases the micropores of the fiber, improves the dyeing rate, air permeability and moisture absorption of the fiber, thereby further adapting to the polyester fiber Silk-like.

By imitating silk, the fabric can be made soft, breathable, comfortable, antistatic, and dyeable at normal temperature and pressure. Through cationic modification of multi-functional imitation wool, the fabric can be made soft to the touch, antistatic, anti-pilling, and co-dyed with wool at normal temperatures and pressures.

Introduction to raw materials

poly Ester is a general term for polymers obtained by polycondensation of polyols and polybasic acids.

is a type of polymer containing ester functional groups on its main chain. Polyester can be divided into saturated polyester and unsaturated polyester.

Usually composed of one or more polybasic acids (anhydrides) and one or more Polyols are produced by polycondensation, mainly referring to polyethylene terephthalate (PET), but also customarily include linear thermoplastic resins such as polybutylene terephthalate (PBT) and polyarylate (see color diagram). .

Preparation method

ester exchange polycondensation method

Direct esterification polycondensation method

Ethylene oxide method

Performance and application

It is a type of engineering plastics with excellent performance and wide range of uses. It is widely used in fibers, films and plastic products.

PET plastic has a highly symmetric molecular structure and a certain crystal orientation ability, so it has high film-forming and fiber-forming properties. PET plastic has good optical properties and weather resistance, and amorphous PET plastic has good optical transparency. In addition, PET plastic has excellent wear resistance, dimensional stability and electrical insulation.

PBT and PET have similar molecular chain structures, and most of their properties are the same, except that the main chain of the molecule is composed of Two methylene groups have become four, so the molecules are more pliable and the processing performance is better. Polyester products can be used to form fibers and can be used as raw materials for weaving textiles.

The fabric is comparable to natural fabrics in terms of wearing comfort and dyeing brightness, and is lower in price than natural silk, and can generate high added value.

Cationic modified polyester filament is indistinguishable from polyester filament. If you want to distinguish, you can usually only use dyeing! Cationic raw materials are generally darker!
