Advanced production process: Base fabric foundation + process empowerment

The outstanding quality of thermochromic spunlace nonwoven fabric stems from the company's dual control system of "precise base fabric production + customized processing". The production process starts with high-quality spunlace base fabric and is endowed with thermochromic characteristics through three exclusive post-treatment processes. The entire process follows the principle of "fine management and full-process quality control", with key steps as follows:

1. Core base fabric production process: Firstly, raw material pretreatment is carried out. According to customer requirements, base materials such as polyester, viscose, Tencel, silk, bamboo fiber, and pure cotton are selected and proportioned. After sorting, opening, and mixing, precise measurement is conducted to ensure uniform fiber distribution. Then comes the stage of web formation, where advanced carding machines and cross-laying technology are employed to card the fibers into a uniform single-fiber layer and cross-lay them, forming a structurally stable web. In the core spunlace reinforcement stage, multiple sets of high-pressure spunlace heads are used to impact the web with high-speed water jets, causing the fibers to entangle and bond, forming a dense three-dimensional web structure. The water pressure and nozzle arrangement are precisely controlled to ensure that the base fabric meets the standards for strength, hand feel, and flatness.

2. Process One: Drip Molding Empowerment: Customized thermochromic powder and special PVA slurry are mixed in precise proportions and stirred evenly to form a stable thermochromic slurry. An automated drip molding machine is used to precisely apply the slurry in a dot pattern according to the design on the spunlace base fabric. The fabric then undergoes a constant-temperature drying process to firmly bond the PVA slurry with the base fabric, ensuring stable dot-shaped thermochromic effects. The finished product changes color precisely in the dot areas when exposed to the set temperature, with a strong three-dimensional effect.

3. Process Two: Printing Empowerment: Special printing slurry and thermochromic powder are mixed in appropriate proportions to create a thermochromic printing slurry. A dedicated screen is made based on the customer's design pattern. A flat or rotary screen printing machine is used to precisely print the thermochromic slurry onto the base fabric according to the pattern. After low-temperature drying and color fixation treatment, the printed pattern adheres closely to the base fabric, ensuring clear patterns and sensitive thermochromic responses. When exposed to temperature, the pattern areas of the finished product change color as preset, demonstrating strong creativity.

4. Process Three: Coating Empowerment: Thermochromic powder and special bonding slurry are thoroughly mixed to form a uniform thermochromic coating slurry. The spunlace base fabric is fixed on a coating machine, and the slurry is evenly coated on the fabric surface through a precisely adjusted scraper, controlling the coating thickness for uniformity. After drying and curing, a complete thermochromic coating is formed. When exposed to temperature, the entire surface of the finished product changes color uniformly, with rich and consistent coloration.

5. Quality Inspection of Finished Products: All finished products must pass multiple tests including thermochromic performance (accuracy of temperature sensing, sensitivity and stability of color change), physical performance (strength, abrasion resistance), and environmental protection indicators (absence of harmful residues) to ensure that each batch meets the customer's customized requirements and industry standards.
