The difference between high-end T-shirt customization and regular T-shirt customization

-
When you hear the word "high-end" when customizing a high-end T-shirt, it feels obvious that the price is relatively expensive. Of course, there must be a difference in customization prices between high-end T-shirts and regular T-shirts, but quality cannot be judged by price, otherwise you will fall into the trap of "high-end".   Only by knowing the difference between high-end T-shirt customization and regular T-shirt customization can one avoid being trapped by "high-end" traps. The so-called "high-end" always refers to quality, not appearance. Nowadays, some so-called high-end T-shirts are customized with fashionable styles and high-end visual effects, especially with superb photography and photo editing techniques. Coupled with the term "high-end T-shirt customization", many enterprises are trapped, but when they actually get them, the difference is far. How to avoid falling into the trap of "high-end T-shirt customization"...

The difference between TPU and PU

-

Polyurethane thermoplastic elastomers can be classified into two types: polyester and polyether, with white irregular spherical or columnar particles and a relative density of 1.10-1.25. The polyether type has a lower relative density than the polyester type. The glass transition temperature of polyether type is 100.6-106.1 ℃, and that of polyester type is 108.9-122.8 ℃. The brittleness temperature of polyether type and polyester type is lower than -62 ℃, while the low temperature resistance of hard ether type is better than that of polyester type.


The outstanding characteristics of polyurethane thermoplastic elastomer are excellent wear resistance, excellent ozone resistance, high hardness, high strength, good elasticity, low temperature resistance, good oil resistance, chemical resistance and environmental resistance. Polyether can be used in humid environments. The hydrolytic stability of type ester is much higher than that of polyester type.


TPU (thermoplastic polyurethane elastomer) is an emerging plastic variety. Because TPU has good processability, weather resistance, and environmental protection, it is widely used in shoe materials, pipes, films, rollers, cables and wires and other related industries. Polyurethane thermoplastic elastomer, also known as thermoplastic polyurethane rubber, referred to as TPU, is an (AB) n-type block linear polymer. A is a polyester or polyether with a high molecular weight (1000-6000), and B is a linear polymer containing 2-12 For diols with chain carbon atoms, the chemical structure between AB chain segments is connected by diisocyanate, usually MDI. The general structural formula is shown in the figure. Thermoplastic polyurethane rubber is cross-linked by hydrogen bonds between molecules or light cross-linking between macromolecular chains. As the temperature increases or decreases, these two cross-linked structures are reversible. In the molten state or solution state, the intermolecular forces weaken, but after cooling or the solvent evaporates, strong intermolecular forces connect them together, restoring the original solid properties.


Polyurethane thermoplastic elastomer is non-toxic, odorless, soluble in solvents such as cyclohexanone, tetrahydrofuran, dioxane, and dimethylformamide. It can also be dissolved in toluene, ethyl acetate, methyl ethyl ketone, and acetone in appropriate amounts. In the mixed solvent composed of the proportion, it appears colorless and transparent, and has good storage stability.


PU polyurethane is a general name for polymer compounds generated by the reaction of diisocyanate or polyisocyanate with compounds with more than two hydroxyl groups. Its main chain contains many repeating NHCOO groups. Commonly used diisocyanates include toluene diisocyanate (TDI), diphenylmethane diisocyanate (MDI), hexamethylene diisocyanate (HDI), isophorone diisocyanate (IPDI), dicyclohexylmethane diisocyanate (HMDI), and polyethylene diisocyanate. Methyl polyphenyl polyisocyanate (PAPI), xylylene diisocyanate (XDI), etc. According to the different hydroxyl components used, it can be divided into two types: polyester type and polyether type. It can be used to manufacture plastic products, wear-resistant synthetic rubber products, synthetic fibers, hard and soft foam plastic products, adhesives and coatings, etc.


The properties of rubber materials made from different formulas are also different. These properties refer to mechanical properties and physical properties.


TPU and PU are essentially made of the same material. But when making these two kinds of rubber materials. The formulas they use are not the same. These two types of rubber materials are divided into many types of properties.

Buying a T -shirt, choosing fabrics is the key

-
 It is indispensable for the comfort and fit of the T -shirt. Especially in summer, whether it is going to work or working, smart men will take it as the first choice. And men's T -shirts are both comfortable and can be truly ironed, which means that they have the appearance of chemical fiber and the feel of cotton. Therefore, silk and glue fibers in domestic markets are the most common. How to choose your favorite T -shirt according to different fabrics, how to clean and maintain T -shirts.   1. Ordinary cotton fabric      Casual T -shirts mostly use ordinary cotton fabrics. The T -shirt of this fabric is comfortable, but it is slightly worse.   2. Silk cotton fabric      Silk cotton fabrics use cotton as raw materials, make high weaving gauze by refined texture, and then make special processing processes such as fur and silk light to make a polished, soft and anti -wrinkle high -quality silk gauze. The high -quality knitted fabric made of t...

What are the details to pay attention to when customizing a team uniform t-shirt? Some individual users choose customization for their personal needs, and many companies also customize group uniforms to increase employee identification and sense of belonging. Customization has become an increasingly popular choice for both businesses and individuals. There are many aspects to pay attention to when customizing T-shirts, and there are many factors that can affect the quality of team uniform T-shirt customization. Next, let's take a look at the precautions for customizing team uniform T-shirts. Firstly, do a good job in positioning The purpose of a team uniform t-shirt has a significant impact on its customization, such as whether it is for casual wear or work activities, and what special features are required for t-shirt customization. Different styles have different uses, round necked T-shirts are generally used for events, and they are also given as gifts to customers during produc...

What are the characteristics of T -shirt fabrics?

 1. Ordinary cotton fabric Casual T -shirts mostly use ordinary cotton fabrics. The T -shirt of this fabric is comfortable, but it is slightly worse. It's easy to wrinkle, and it is easy to deform after launching. 2. Cotton fabric The feel is better, comfortable and environmentally friendly. The heavy weight is generally between 160 and 300 grams. It is too thin and very transparent. The branch refers to the average length of the cotton fiber, the higher the softened, and the veil is divided into general gauze, semi -essence and fine gauze, and the surface of the veil fabric will be relatively rough, especially the dark fabric will have white gauze with white gauze. point. The surface of the fabric of the fine yarn is relatively neat and soft. 3. Silk cotton fabric Silk cotton fabrics use cotton as raw materials, make high weaving gauze by refined texture, and then make special processing processes such as fur and silk light to make a polished, soft and anti -wrinkle high -quality ...
