Dyeing Acid

With over ten years of experience in the R&D and manufacturing of textile printing and dyeing auxiliaries, Dyeing Acid serves as a basic functional raw material for adjusting bath pH value and promoting dyeing and color fixing in dyeing and printing processes. Ordinary Dyeing Acid on the market generally suffers from problems including weak pH buffering capacity, large bath fluctuation, fabric shade deviation and high wastewater treatment costs. Based on multiple rounds of formula optimization supported by factory emulsification production lines and R&D laboratories, we have developed a high-buffer composite dyeing acid to stabilize bath environment and reduce customers' production losses.

Workshop actual application data shows that the buffering range of this product is stable, and no large fluctuation of bath pH occurs after addition, which can effectively reduce fabric color spots and color differences, and the uniformity of finished fabric shade is improved by over 95%. The low-irritation formula reduces the difficulty of neutralizing dyeing wastewater, complying with domestic environmental discharge requirements. It remains free of crystallization and delamination when hermetically stored at room temperature for 12 months, compatible with all categories of printing and dyeing equipment including jigger dyeing machines, jet dyeing machines and flat screen printing machines. The annual shipment volume of Dyeing Acid exceeds 240 tons, covering major dyeing industrial clusters in Jiangsu, Zhejiang, Shandong and Guangdong in China, with long-term stable exports to textile countries including Vietnam, Bangladesh and Pakistan, and printing and dyeing factories at home and abroad conduct continuous replenishment all year round.

Most manufacturers' Dyeing Acid has single buffering performance only fit reactive dye dyeing, while this dyeing acid is compatible with all categories of dyes including reactive, disperse, acid and reducing dyes, applicable to pH adjustment procedures of dyeing and printing of various fabrics such as cotton, viscose, polyester and nylon. The workshop is equipped with a stable production team of 16-20 people, paired with a full-time R&D engineer team, which can adjust buffering strength according to customers' dye vat capacity, fabric weight and dye system, undertaking OEM private label customization. The minimum order quantity is 1000kg, free samples are delivered, with international logistics fees borne by purchasers, and the debugging cycle for customized formulas is 15-30 days.

We are a source manufacturer with a 10,000 square meters self-owned workshop without markup by intermediate traders, achieving full independent control from raw material compounding to finished product filling. Every batch of Dyeing Acid undergoes triple testing of pH buffering performance, stability and fabric sampling, and third-party on-site inspection is open. Stable supply capacity meets the long-term bulk purchasing demands of overseas purchasers.

PH adjustment for jigger and jet dyeing of reactive dyes on pure cotton and viscose fabrics; dye promotion for disperse/acid dye dyeing of polyester and nylon; pH regulation of printing paste; pH control of cheese dyeing of knitted and woven fabrics.

The factory is located in Tudian Industrial Park, Tongxiang, Jiaxing, Zhejiang Province, with a standardized production workshop of 10,000 square meters, equipped with 9 sets of silicone synthesis equipment and 6 sets of special emulsification, stirring and dispersion production lines, achieving a stable monthly comprehensive production capacity of 1000 tons to accept large overseas orders of Dyeing Acid. The workshop has fixed production staff of 16 to 20 people, with flexible supplementary production teams available during peak order seasons. All types of basic chemical raw materials are stocked in large quantities all year round. The delivery cycle of standard dyeing acid is only 3-5 days, while customized buffering modified products take 3-7 days. All repeat customer orders are prioritized for production scheduling to greatly shorten delivery waiting time for overseas customers.

 

An independent R&D laboratory and fabric application testing laboratory are matched on the factory premises, staffed by many senior chemical engineers dedicated to formula debugging and fabric sampling testing. We have focused on the printing and dyeing auxiliary track for ten years, with all products independently developed and produced, eliminating markup by multi-layer middlemen to provide more competitive purchasing prices and uninterrupted stable supply guarantee for agents at home and abroad.

An independent rapid response technical after-sales team has been set up to provide full-process technical matching services before, during and after order placement for Dyeing Acid. In the pre-sales stage, engineers issue accurate additive proportion plans for pH adjustment combined with customers' dye vat models, main fabrics and dye categories, and provide free samples for sampling comparison testing. Real-time progress of processing, filling and packaging is synchronized during order production, and workshop production photos and videos can be sent on demand to follow up and ensure on-time delivery throughout the process. When customers encounter color spots, color differences and pH fluctuation during dyeing production, technical staff remotely adjust adding processes online in real time, and issue special improvement plans in emergency working conditions.

All products come with a unified quality guarantee period of 6 months to 1 year. If fabric dyeing color difference and color spot losses are caused by inherent product quality defects, brand-new Dyeing Acid will be delivered free of charge with full-process free online technical debugging simultaneously to eliminate production and use concerns of overseas customers.

Clear and flexible payment cooperation rules are formulated for purchasers at home and abroad, adapting to different order types and purchasing volumes. Standard Dyeing Acid orders implement 30% advance payment to arrange production, with delivery after full settlement of balance; customized modified formulas and exclusive private label packaging orders require 50% advance payment to commence formula debugging and production, and the remaining balance shall be settled before delivery.

Two mainstream settlement currencies of US Dollar and RMB are supported for cooperation. Tiered discount offers can be negotiated for annual framework bulk purchase orders. Flexible settlement cycles can be communicated for long-term cooperative high-quality agents. Trade delivery modes support two mainstream foreign trade clauses of EXW factory pickup and FOB port delivery, matching the trade and settlement habits of overseas purchasers in different regions.
