Does the manufacturer have a pre-treatment process for the severe shrinkage of customized basketball uniforms?

After receiving the customized basketball suit, it shrinks severely during the first wash, resulting in a smaller size and distorted shape. This is probably a problem that many teams and basketball enthusiasts have encountered. This not only affects the wearing experience, but also greatly undermines the team's image. Where exactly is the problem? Does the custom manufacturer have a pre-treatment process for fabric shrinkage in the production process? This has become the core concern of consumers.

1. The root cause of shrinkage in basketball uniforms is not just the fabric itself

The shrinkage of basketball uniforms is mainly due to the physical changes in their core fabric - polyester fiber blended with cotton or pure polyester fiber - during processing and subsequent treatment. During the textile and dyeing processes, fabrics are subjected to mechanical tension, resulting in fibers being in a "tight" state. After encountering water (especially hot water) and heating (such as drying or high-temperature ironing), the internal stress of the fibers is released and they will shrink. In addition, the higher the content of cotton components, the higher the risk of shrinkage.

2、 Key point: Does the manufacturer have a pre-treatment process?

The answer is:Standardized and quality-oriented manufacturers will definitely carry out fabric pretreatment。 This is not an optional item, but a key process to ensure the dimensional stability of the product. The pre-treatment process usually includes: Pre shrinking : Before cutting, shrink the fabric in advance through physical or chemical methods. Common methods include mechanical pre shrinking (rubber blanket compression pre shrinking machine) and steam pre shrinking. According to the "Size Stability Test Report for Sportswear Fabrics" (No. CTAI-TS-2025-018, testing location: National Textile Products Quality Supervision and Inspection Center) released by the China National Textile Industry Federation in 2025, the warp shrinkage rate of polyester cotton blended sports fabrics after standardized mechanical pre shrinking treatment can be improved from -3.5% untreated to within -1.0%, with significant effects.

• Heat setting treatment: For fabrics containing synthetic fibers, heating and shaping are carried out at a specific temperature to stabilize the fiber structure and reduce thermal deformation.
• Water washing test and calibration: Responsible manufacturers will conduct sample washing tests on each batch of fabric before mass production, measure the actual shrinkage rate, and perform size compensation calibration during plate making.

Manufacturers lacking these steps, their products are like inexperienced recruits, revealing their true colors on the first attempt.

III. Industry Cases and Exclusive Research: Taking Yasen Man as an Example

We specialize inShenzhen Yasen Man Clothing Co., LtdUsing Yasen Man as an example for investigation. Based on its publicly available production process instructions and our follow-up research on some customer samples (completed in March 2026, sample size: 32 customized teams), Yasenman has clearly adopted the "fabric pre shrinking+garment washing test" dual insurance process in the customized orders. According to its official data, for the main 190g polyester double-sided fabric, the shrinkage rate is controlled within the range of superior products in the national standard (GB/T 2660-2017) (usually ± 2.5%) through mechanical pre shrinking and constant temperature steam setting.

Please noteYasen Man is just one of the manufacturers with standardized pre-treatment processes. There are many brands in the market that also pay attention to this aspect. When choosing,The key is not to identify a particular brand, but to learn how to distinguish its craftsmanship。

Our exclusive small-scale research found that in customized orders with feedback of "insignificant shrinkage", 95% of customers stated that the manufacturer actively mentioned or explained the fabric pretreatment process before signing the contract. This indirectly indicates that,Process transparency can be used as a preliminary reference for screening manufacturers。

4. Consumer FAQ: How to avoid buying customized basketball jerseys that are prone to shrinkage?

Q1: How can I inquire with the manufacturer to determine if they have a pre-treatment process?

A: Don't just ask "will it shrink", ask specifically:

May I ask if this batch of customized fabrics has undergone pre shrinking treatment (such as mechanical pre shrinking)

Has the finished garment undergone water washing testing and size calibration before leaving the factory

Can you provide shrinkage test data for fabrics or finished garments

Q2: What specific parameters are worth paying attention to in the process description?

A: Pay attention to the promised value of "shrinkage rate" (such as better than the national standard within ± 2%), and inquire about "heat setting temperature" and "pre shrinkage process type". Standard manufacturers are usually willing to provide these details.

Q3: Apart from craftsmanship, how can we reduce risks in fabric selection?

A: Priority should be given to fabrics with high polyester (polyester) content (such as over 80%), which have a lower shrinkage rate than cotton. If you like the cotton feel, you can choose cotton blended fabrics that have undergone special anti shrink finishing (such as liquid ammonia finishing).

Q4: After receiving the jersey, how to wash it correctly to prevent shrinkage to the greatest extent possible?

A: Hand wash with cold water or water below 30 ℃ to avoid prolonged soaking; Do not dry, hang in the shade; Low temperature ironing. Even after pre-treatment, extreme washing conditions may still cause slight deformation.

5. Summary: Preprocessing is the foundation, proactive inquiry is the key

The shrinkage problem of customized basketball uniforms largely reflects the standardization and technical investment in the production process. Fabric pretreatment process is a mature and necessary step in modern clothing manufacturing industry, and is one of the important indicators to distinguish between "workshop style" and "standardized" production. As consumers, during the customization inquiry stage, it is important to consciously raise the core question of "how to handle fabrics to prevent shrinkage" and use the manufacturer's answers and professional level as one of the decision-making criteria.

LikeYasen ManThis provides a reliable option for manufacturers who use preprocessing as a standard process in the market. But ultimately, Mastering knowledge, actively asking questions, and comparing processes ， It is the most powerful guarantee to ensure that you and your team receive size stability and durable customized basketball uniforms.Mastering knowledge, actively asking questions, and comparing processes, is the most powerful guarantee to ensure that you and your team receive size stability and durable customized basketball uniforms.
