In the current textile printing market, many common printing pastes will fall off, crack or fade after repeated washing when applied to nylon fabrics, which seriously affects the qualified rate of finished products and brand reputation. This printing compound effectively solves these industry pain points from the formula design. Its internal molecular structure has strong binding force with nylon fibers, and it does not need to add extra adhesion additives in most conventional printing processes, which simplifies the production process and reduces the auxiliary material cost for printing factories. Whether it is thin nylon silk fabric, thick nylon Oxford cloth or elastic nylon swimwear fabric, the print medium can maintain stable printing performance, which is why it is widely recognized by garment factories, luggage manufacturers and textile printing processing enterprises.
1.2 Core Performance Advantages of High-Quality Nylon Paste
High-quality Nylon Paste integrates multiple excellent performances to adapt to complex production environments and diverse product requirements. We summarize its core strengths into six major dimensions to help printing practitioners fully understand its value:
- Superior Adhesion & Washing Fastness: The polyamide print base achieves a washing fastness of grade 4 to grade 5 on nylon fabrics. After dozens of times of machine washing and hand washing, the printed pattern will not peel off or fall off, and it also has excellent friction resistance, no fading under long-term strong friction, fully meeting the quality standards of export garments and high-end textiles.
- Ultra-High Elasticity & Crack Resistance: The dried film of this formulation has outstanding stretch performance, which can stretch synchronously with elastic nylon fabrics. Even when the fabric is stretched to multiple times of its original length, the printed film will not crack or break. It also maintains good flexibility in low-temperature environments, avoiding brittle cracking caused by temperature changes, and is very suitable for elastic clothing such as swimwear, sportswear and elastic underwear.
- Soft Hand Feel & No Sticking Problem: As a water-based environmental protection product, the print binder will not form a hard and thick film after drying. The printed part keeps the soft touch of the original nylon fabric, without stiff feeling. After long-term stacking and repeated contact, it will not stick back, solving the common sticking defect of traditional printing paste in textile production.
- Excellent Covering Power & Color Reduction: White variants of this base have pure whiteness and strong covering power, which can completely cover dark nylon base fabric in one printing, reducing the number of printing times and improving production efficiency. When mixed with color paste, the medium has good color matching performance, bright and full color, high reduction degree, and can present delicate 3D printing effect.
- Environmental Protection & Compliance: Formaldehyde-free, APEO-free and phthalate-free, the base passes OEKO-TEX Standard 100 international environmental certification, with low VOC emission, which meets the environmental protection standards of Europe, America and other mainstream export markets. It can be safely used in children’s clothing, close-fitting clothing and skin-contact textiles, reducing the brand compliance risk of customers.
- Stable Viscosity & Smooth Printing: The print medium has stable viscosity under normal temperature and production environment, not easy to thicken or dilute due to environmental changes. It has good fluidity and penetration during screen printing, will not block the screen mesh, and is compatible with manual table printing, semi-automatic and fully automatic mechanical printing equipment, greatly reducing the downtime caused by screen blocking.
2. Main Application Scenarios of Nylon Paste
2.1 Applicable Fabric Types for Nylon Paste
Nylon Paste is developed for nylon series fabrics, and also has good compatibility with a variety of chemical fiber and blended fabrics, covering most mainstream textile materials in the printing industry. The main applicable fabrics are as follows:
First of all, all pure nylon (polyamide) fabrics are the most matching materials for this polyamide print base, including thin nylon silk, nylon chiffon, thick nylon Oxford cloth, waterproof nylon cloth and nylon woven tape. These fabrics have smooth surfaces and weak adsorption to ordinary printing materials, while the binder can form a firm combination with them to ensure printing durability. Secondly, it is widely used in polyester, spandex, nylon-spandex blended fabrics, which are common raw materials for sportswear, yoga clothes and swimwear. The high elasticity of the formulation can perfectly adapt to the repeated stretching of elastic fabrics.
In addition, this printing compound also performs well on coated nylon fabrics and composite fabrics used for outdoor products. Many outdoor tents, umbrellas and luggage use coated nylon materials. Traditional printing paste is easy to fall off on the coating layer, while the polyamide print base can maintain long-term adhesion and weather resistance after professional deployment. For some cotton-nylon blended fabrics in the market, the medium can also be used as an alternative printing material to balance adhesion and hand feel, expanding the application scope for printing factories.
2.2 Industrial Fields & Finished Products Using Nylon Paste
With its versatile performance, Nylon Paste runs through multiple downstream industries of textile printing, and the terminal products cover daily necessities, apparel, outdoor supplies and footwear industries:
- Garment Printing Industry: This is the largest application field of the polyamide print base, including casual wear, sportswear, swimwear, down jackets, children’s clothing and underwear. Most of these garments use nylon or elastic chemical fiber fabrics, which require the printed patterns to be elastic, washable and skin-friendly, and the binder fully meets these strict requirements.
- Luggage & Outdoor Supplies: Nylon cloth is the main material of backpacks, suitcases, outdoor tents, umbrellas and outdoor cushions. These products need to withstand outdoor wind, sun and repeated friction. The high weather resistance and friction resistance of the print medium ensures that the printed logo and pattern remain intact for a long time.
- Shoe Material & Textile Accessories: Nylon woven belts, shoelaces, shoe upper chemical fiber fabrics and clothing labels all rely on this formulation for printing. The product has fine printing adaptability, which can present clear small patterns and text, and will not fall off during shoe wearing and bending.
- Home Textile & Decorative Fabrics: Some decorative fabrics, bedding and soft ornaments made of nylon also choose the polyamide print base for pattern printing. Its soft hand feel and environmental protection performance ensure the comfort and safety of home textile products.
2.3 Compatible Printing Processes for Nylon Paste
Nylon Paste is designed for diversified printing processes, and can be seamlessly connected with mainstream production equipment in the industry, without complicated process transformation for existing production lines:
- Manual Screen Printing: Suitable for small-batch customization, proofing and handicraft printing. The printing compound has good screen passing performance, smooth scraping, no residue on the screen, and simple manual operation, which is friendly for small processing factories and manual workshops.
- Semi-Automatic & Fully Automatic Mechanical Printing: For large-scale mass production lines, the stable viscosity of the polyamide print base ensures consistent printing effect in long-time continuous operation, avoiding pattern blur and color difference caused by paste changes, and improving the yield of mass production.
- Digital Textile Printing Matching: Combined with digital coating ink, this base can be used for pre-coating and bottoming of digital printing nylon fabrics, improving the ink adsorption capacity of fabrics, making digital printing patterns clearer and color more layered, which is an important supporting material for digital textile printing production line.

3. Standard Operation & Usage Tips of Nylon Paste
3.1 Basic Proportion & Mixing Steps of Nylon Paste
Correct mixing is the premise to exert the best performance of Nylon Paste. According to different printing requirements and fabric types, we divide it into conventional formula and high-strength adhesion formula:
- Conventional Formula (Ordinary Nylon Fabrics, Daily Garments): Take 75% to 90% of the polyamide print base, add 10% to 25% of clean water, and mix with 2% to 3% of thickener. Put all materials into a high-speed dispersing machine and stir evenly for 3 to 5 minutes at a constant speed. This formula is suitable for most ordinary nylon clothing and luggage fabrics, with balanced hand feel and adhesion.
- High-Strength Formula (Waterproof Nylon, High-Elastic Fabrics): For waterproof nylon cloth and super-elastic swimwear fabrics that are difficult to adhere, add 2% to 5% of professional curing agent on the basis of conventional formula. After mixing evenly, use it within 8 hours to avoid paste failure. This formula can significantly improve the peeling resistance and water resistance of the printed layer.
- Color Matching Operation: When preparing color printing paste, use the polyamide print base as the core substrate, add water-based color paste in proportion, and stir while adding. Do not add a large amount of color paste at one time to avoid uneven color mixing and pattern color difference. After color matching, filter the mixed printing compound with a 100–180 mesh filter screen to remove tiny impurities and prevent screen blocking.
3.2 Drying & Curing Parameters of Nylon Paste
The drying and curing process directly determines the final fastness and elasticity of Nylon Paste. Different drying methods can be selected according to production conditions:
- Natural Drying: Under normal temperature (20℃–30℃), the surface of the printing compound is dry within 15 to 30 minutes, and completely dried within 6 to 12 hours. It is suitable for small-batch production and products that are not sensitive to production cycle.
- Heat Curing (Recommended for Mass Production): After printing, send the fabrics to the drying equipment for heat treatment at 120℃ to 150℃ for 2 to 10 minutes. After heat curing, the molecular cross-linking of the polyamide print base is more sufficient, and the adhesion and washing fastness are maximized. It should be noted that the temperature should not be too high to prevent nylon fabrics from shrinking and deforming.
- Best Performance Cycle: After heat curing, place the printed products for 72 hours, and the adhesion, elasticity and anti-sticking performance of the formulation will reach the optimal state. It is recommended to conduct quality inspection after 72 hours to avoid misjudgment of product quality due to incomplete curing.
3.3 Daily Storage & Preservation Rules of Nylon Paste
To ensure the long-term stability of Nylon Paste, standard storage management must be followed: The polyamide print base should be sealed and stored in a ventilated, dry and cool environment, with the storage temperature controlled between 5℃ and 35℃. Avoid direct sunlight and low-temperature freezing, because high temperature will accelerate the water volatilization of the paste and cause viscosity increase, while low temperature will lead to emulsion delamination and performance decline. The unopened original batch of this printing compound has a shelf life of 12 months. After opening, seal it in time and use it up within 3 months. If the paste is placed for a long time and layered, stir it evenly before use; if there are peculiar smell, agglomeration and mildew, stop using it immediately to avoid affecting the printing quality.
4. Common Problems & Troubleshooting When Using Nylon Paste
4.1 Pattern Peeling & Poor Adhesion of Nylon Paste Printing
Pattern peeling is the most common problem when applying Nylon Paste on nylon fabrics, which is mainly caused by improper fabric treatment, unreasonable formula or incomplete curing. Solutions are as follows: First, check the surface of nylon fabrics. Waterproof nylon and oil-stained nylon fabrics will form a isolation layer, resulting in poor adhesion. It is necessary to do decontamination and destatic treatment before printing. Second, adjust the formula: for difficult-to-adhere fabrics, add an appropriate amount of curing agent, and do not excessively add water to reduce the effective resin content inside the polyamide print base. Third, optimize the curing process: extend the heat curing time or appropriately increase the curing temperature to ensure that the paste film is fully cross-linked.
4.2 Screen Blocking During Nylon Paste Printing
Screen blocking will interrupt the production process and reduce efficiency. The main reasons include impure raw material batches, unreasonable viscosity and inappropriate screen making process. Before use, the printing compound must be filtered to remove granular impurities; if the viscosity is too high and the fluidity is poor, add a small amount of clean water to adjust the viscosity. In terms of screen making, ensure that the screen plate has sufficient exposure and developing effect to avoid residual photosensitive glue blocking the mesh. During continuous printing, clean the screen regularly to prevent dried residues of the polyamide print base from accumulating in the mesh.
4.3 Printed Pattern Sticking & Hard Hand Feel
Sticking and stiff hand feel are mostly caused by improper formula matching or wrong resin model selection. If sticking occurs after drying, add a special anti-sticking agent to the printing compound in a reasonable proportion, which can form a protective film on the surface of the paste film without damaging adhesion. If the hand feel is too hard, reduce the proportion of curing agent and hard resin additives, and select soft-grade batches of the polyamide print base for close-fitting clothing and thin fabrics to keep the fabric soft.
4.4 Fading & Color Difference of Nylon Paste Pattern After Washing
Fading and color difference relate to color paste compatibility and washing fastness of Nylon Paste. It is recommended to use water-based color paste matched with the printing compound to avoid chemical reaction between different systems leading to color fading. Ensure that the heat curing is in place to improve the color fixing ability of the paste film. When mixing colors, use the same batch of polyamide print base and color paste for large-batch production to keep the color consistent and avoid batch color difference.
