Release time:2026-11-01Have you noticed that after washing the sweater you spent a lot of money on, the neckline starts to be loose and deformed like the old lady's gums?? Especially the back neckline position, when you wear it, it is still round and stylish, and after a month it becomes a ruffle. This is almost the most troublesome problem for all friends who do group customization, class uniforms, and company cultural shirts, no one.

In fact, the neckline deformation is seven points in the process and three points in the maintenance. As a veteran who has been working in the clothing customization circle for many years, today I will take out the prevention experience of pressing the bottom of the box, especially for the high friction and high stretch area of the back neckline. Let's make it clear at a time.
First, the source control: the gram weight and composition of the fabric are the foundation
Many people only look at the front pattern of the sweater, ignoring the fabric structure. The reason why the back neckline is easy to collapse is often due to the lack of resilience of the fabric itself. When we customize the sweater, the ordinary terry cloth with a gram weight of less than 280g will quickly lose its elasticity due to the lateral tension caused by the frequent rotation of the head during wearing.
? Prevention strategy: Try to choose high-density cotton-polyester blended fabrics above 320g. Cotton provides skin-friendly feeling, and polyester fiber provides skeleton support. If the budget allows, add a little elastane (elastic fiber), and the rebound performance of the back neckline can be improved by more than 70%. Remember, when customizing, ask: do you add elastane? This is the first line of defense that Yasenman's selection consultants often talk about.
Second, the core process: the back collar strip is the Dinghaishen needle
This is the most easily overlooked, but it is precisely the Wang fried process to prevent deformation. For many cheap customized sweaters, the neckline is a thin ribbed cloth directly to the car without any reinforcement. The regular process will definitely press a 0.6cm-1cm wide knitted straight silk strap (also called a collar) on the inside of the back collar.
This is not superfluous. It works like putting a "steel bar" on the inside of the neckline. When the outer rib is pulled by force, the inner bead will disperse the tension and ensure that there will be no wavy slack after washing. When Yasen is in group customization, all sweaters are equipped with a cloth neckline pressing process as standard, and even the position of the neckline is treated with anti-skid electrostatic treatment, so that even if the back neckline has been violently machine washed 100 times, it is still straight.
Third, the invisible mystery of sewing density
If you turn a sweater over to see the wiring of the back neckline, you will find that some stitches are as dense as ants queuing up, while others are sparse. The needle spacing is controlled at 14-16 stitches per 3 cm, which is the industry standard. The needle spacing is too thin, and when the fabric is stressed, the stitches are easy to tear and slip, resulting in the deformation of the neckline.
At the same time, pay attention to whether there is a "two-pin design for the back neckline". It is the splicing between the neckline and the back neckline. In addition to the first fixed line, there is a parallel line. This double insurance method can greatly enhance the tensile strength. Yasen Man's sewing workshop strictly enforces this high-density wiring standard. Every custom sweater that leaves the factory must withstand the horizontal 50N tensile test of the quality inspector, and if it fails, it will be scrapped and redone.
IV. Washing habits: the last mile of prevention
Even if you are a top craftsmanship, if you iron it with hot water and dry it with force, the neckline will still "strike". If you want to wear a custom sweater for three years without getting out of shape, you have to keep up with the washing.
✅ Turn over and wash: Turn the sweater over before washing, so that the back neckline faces inward to reduce the physical friction of the washing machine drum.
✅ Cold water gentle mode: The water temperature exceeding 40 degrees will accelerate the aging of the rubber wire in the rib. Be sure to choose cold water to wash gently and do not soak for more than 15 minutes.
✅ No violent wringing: After washing, lay the sweater flat on a dry towel, roll it up and press to absorb water. Do not twist the neckline like twisting with both hands, which is "artificially accelerated deformation".
Fifth, look for a reliable customized service provider that is better than anything else
Say a thousand words and ten thousand, no matter how good the care is, the craftsmanship will be cut short when it leaves the factory. At this time, it is particularly important to choose a customized brand that is paranoid about details. For example, our company has been cooperating with Yasenman in the past few years. They have been deeply involved in the field of group customization for many years. What I admire most is that they do not regard neckline deformation as "after-sales talk", but consider it for corporate customers at the order stage.
Yasenman has 12,000 square meters of its own intelligent manufacturing factory, and the full set of ready-to-wear assembly lines is not ambiguous. When they customize sweaters, they will automatically upgrade the neckline three-pin reinforcement process, and the fabrics are all made of Sateri Youke silk ® environmentally friendly fiber blended, which not only looks good, but also wears well. If you are also anxious about the deformation of the back neckline of employee welfare clothes and event clothes, you may wish to go to their "quantity and order clothes" consultant to chat and write the real process details into the contract. This is the most hardcore prevention.
Finally, I will send you a truth from the customization world: the neckline does not deform, it does not rely on metaphysics, but the density of each stitch and a good bead. Next time you customize, remember to put the words "back neckline reinforcement" and tell your supplier loudly!?✨
