The quality of workout clothes can be further divided into two aspects: internal quality and external quality. It is necessary to be familiar with some typical quality problems and understand the causes of those problems.

Today let's discuss the inherent quality.

The intrinsic quality of work out clothing refers to the quality of clothing that cannot be directly observed with the eye. It is largely related to the quality of the fabric, so if the quality of the fabric is strictly controlled, the expectation of good internal quality of clothing should be reasonable. For clothing suppliers, this may require a certain amount of fabric inspection and testing of fabrics according to explicitly or implicitly agreed standards.

The following common questions are typical of the inherent quality of clothing:

1. Color fastness. Color fastness is a sensitive issue for customers. No one likes his or her windbreaker to fade when exposed to sunlight for a long time, and no one is willing to tolerate beautiful seat covers stained with the Athletic sets of the person they are sitting on. There are several types of color fastness, such as light fastness and wet rubbing fastness, which are defined by grade. The tests implemented depend on the quality terms of the contract. The higher the number of levels, the better the color fastness. In many situations, natural fiber fabrics with dark colors (such as black or red) tend to have poor color fastness. The types of dyes, textile materials involved, dyeing operations, and different settings of dyeing parameters can affect the final color fastness.

1. Shrinkage is another sensitive issue. The shrinkage caused by steam pressing can be detected during sample clothing production and should be prevented by carefully setting pressing or other parameters. For example, if it is found during the production of a sample garment that the lining is bonded to the front hanging surface of the garment, it may cause a 2% shrinkage of the hanging surface garment in the length direction. If the bonding lining conditions remain unchanged, the relevant paper pattern may need to be increased by 2% in length to compensate for this. Customers are unlikely to know the potential shrinkage rate when purchasing athleisure wear. Although the pre shrinkage process may still be inevitable, large shrinkage of clothing or different shrinkage between the fabric and lining will undoubtedly lead to customer complaints. Controlling fabric shrinkage, using appropriate processes, and providing appropriate instructions on washing and maintenance labels are all actions that clothing suppliers should take to minimize potential shrinkage issues.

1. C) Safety. The safety issue of clothing is whether the clothing being worn will affect the health or life of the wearer. It should be noted that many countries have already enacted strict regulations on clothing safety, so understanding these regulations is important for clothing suppliers.
2.  

Some safety issues may only be important for certain populations. For example, poor color fastness may affect a baby's health as they are more likely to lick their clothes. If clothing encounters Mars with poor flame retardancy, it may easily put the weak at risk. Safety issues are important for all wearers. These problems are mainly caused by the residual harmful pollutants in clothing. The residual pesticides forma ldehyde and heavy metals in the fabric, if above the acceptable limit, will undoubtedly affect the health of the wearer. These issues also exist for so-called sustainable activewear.

In addition to fabric factors, poor design of clothing or poor management during the garment process can also pose a threat to the wearer, with broken needles left in the garment being a good example.

There are also other factors that can lead to unsafe clothing. Small accessories or accessories on children's clothing may pose a risk of suffocation. Therefore, it is best to design children's clothing without small components and ensure that the accessories can only be pulled down under a reasonable amount of force (such as 90 Newton specified by some buyers). In addition, non durable wooden, cork, leather, shell or glass buttons should not be used on children's clothing.

1. d) Mechanical properties.One of the important mechanical properties of clothing is the strength of fabrics and seams. If the fabric or sewing thread is selected appropriately,If appropriate technical processes are adopted, there is almost no need to pay attention to mechanical strength for athleisure wear women.

    

   However, special attention must be paid to special clothing. For certain jeans, it may be necessary to test the knee burst strength. For certain work clothes, it may be necessary to test the tear strength. Therefore, whether mechanical strength should be controlled and which type of strength test needs to be carried out will depend on the contract terms and the intended use of the clothing.
