The result is a 250G Over Lock Textured Thread that feels gentle against the skin, drapes naturally, and offers superior stretch recovery. Whether you are manufacturing high-fashion apparel, heavy-duty bags, upholstery, or industrial textiles, this thread delivers consistent stitch formation and long-term durability.
The thread runs perfectly on high-speed overlocking (serger) and cover seaming machines, including brands like Juki, Brother, Pegasus, and Yamato.
All the tests in this round were completed under the factory's mass production conditions, benchmarking against the real production and post-use scenarios of large-scale clothing, luggage, and home textile factories. The data were obtained through multiple batch sampling and actual measurement, and possess commercial reference value.
Adapted to mainstream Japanese and Taiwanese high-speed sewing and tensioning equipment, conducting an 8-hour uninterrupted continuous sewing test. The overall thread path is smooth, without heat accumulation, no stalling, and no continuous breakage issues. It is suitable for high-density lock stitching and multi-layer overlapping sewing processes. Compared to ordinary expanded thread, 250G Over Lock Textured Thread has higher thread path stability, effectively reducing the frequency of production stoppage and debugging, and suitable for the high-intensity operation rhythm of clothing factories' assembly lines.
Carried out actual tests on lock stitching for various types of fabrics such as knitted elastic fabric, woven workwear fabric, luggage Oxford fabric, and home textile fabric. The unique air-expanded fiber structure can naturally fill the sewing pinholes, with a dense and tight lock stitching pattern, no holes, no sparse stitches, and neat and uniform finished thread paths, eliminating common process flaws such as skipping stitches, missing seams, and white needle positions, significantly improving the appearance qualification rate of finished products.
Simulated daily stretching, bending, and close-pressing dynamic scenarios of clothing, conducting 5000 times of repeated stretching cycle tests. The thread response to stretching is uniform, the rebound and reset speed is stable, and there are no issues such as loose thread paths, local wrinkling, or bulging at the sewing position. It perfectly meets the sewing requirements of high-stretch sports clothing, elastic waistbands, and close-fitting underwear with frequent deformation.
Carried out reciprocating friction tests using a standard fabric wear tester, while simulating the daily washing and friction wear scenarios of finished clothing. The expanded surface fiber structure is stable, not prone to shedding, scattering, or delamination, and the lock stitching position remains firm even after long-term use, without local broken or detached stitches, meeting the long-term durability standards for clothing and luggage.
Sampled and compared multiple batches of the same color thread materials, calibrated color differences using professional spectrophotometric color measurement equipment. The color difference in batch production is controlled within the industry's advanced standards. After finished sewing, the same type of clothing and luggage have no color discontinuity, and large-scale orders can achieve zero color difference implementation, meeting the standardized mass production requirements of brands.
After being stored in a dry environment at room temperature for 36 months and sampled for testing, the thread showed no brittleness, hardening, or moisture-induced lumping. The thread path, elasticity, and tensile strength performance were consistent with the new thread. The inventory tolerance rate was high, suitable for factory batch inventory.
The thick-and-thin sections create micro-air pockets along the thread surface. This not only reduces friction against needles and fabric but also gives the finished seam a plush, non-scratchy feel—ideal for children's clothing, underwear, and sportswear.
Textured polyester inherently offers better stretch than flat filament threads. JOHNSON® threads recover quickly after being stretched, preventing loose or puckered seams in knit fabrics. This makes them perfect for activewear, leggings, and elasticated waistbands.
The textured structure provides a "bulky" appearance, which fills needle holes and seam grooves more effectively than conventional threads. This results in cleaner, more professional overlock seams with fewer skipped stitches.
Every batch is produced under strict spectrophotometric control in our in-house dyeing facility.
JOHNSON® is not a trading company. We operate a vertically integrated production facility in China, covering everything from polymer extrusion to texturing, twisting, dyeing, and winding. By eliminating intermediaries, we offer factory-direct pricing, faster lead times, and full traceability.
Most competitors use simple false-twist texturing, which produces a harsh, wiry feel. JOHNSON® employs dual-nozzle air texturing systems, creating random loops and slubs that mimic the hand of cotton but with polyester's strength. This technology is protected by our in-house engineering team.
Because we control every step, we can tailor:
As a manufacturer with our own 25,000 m² facility, we welcome customers to audit our production lines. Our operations include:
A: It is fully compatible. The thread has high loft and strong bearing capacity. When multiple layers of materials are stacked and locked, it is less likely to break or jump, and it is suitable for mass production sewing of workwear, bags, thick home textiles, etc. The finished product has tight and solid lock edges.
A: No need to modify the equipment or replace special accessories. Just appropriately lower the basic pressing tension of the equipment, and you can take advantage of the fluffy lock edges of the thread material, avoiding tight and wrinkled sewing positions. Novice operators can also quickly get started.
A: It eliminates the hard texture of traditional hard thread materials, while maintaining high strength and high softness. The lock edges of the finished product do not irritate the skin and do not wrinkle, and at the same time, the production stability is stronger, the breakage rate is lower, and it can effectively reduce the factory's defective rate and production costs.
A: It supports full-dimensional factory customization. You can adjust the thread thickness, twist, lubrication formula, and tube size according to production needs. At the same time, it can precisely match various exclusive color numbers and be compatible with brand-specific production standards.
A: It adopts high-temperature and high-pressure closed-loop dyeing technology, with color fastness meeting standards. Regular washing and machine washing are not likely to cause color loss or color mixing; the elastic structure of the thread material is stable, and the thread stitches do not loosen or deform after washing, and the product appearance is stable and long-lasting.
A: The entire process uses environmentally friendly and gentle additives, without irritating residues. The thread stitches are soft and do not irritate the skin. It has passed textile skin contact safety testing and can be safely used in infant clothing, close-fitting underwear, sports tight-fitting clothes and other high-end categories.
