Enhancing Every Garment
Quality Driven, Progress Focused
Start with the proposed interlining model, the actual shell fabric and the production-representative fusing machine. A fabric and interlining combination is not confirmed by a generic product description alone.
Use the applicable product reference as a starting point, then document the measured temperature, dwell time and pressure. After cooling, inspect adhesion, appearance, hand feel, shrinkage, adhesive strike-through and the relevant wash or dry-cleaning performance. Confirm the final condition only after the buyer’s own production-representative evaluation.
Share the shell-fabric composition and weight, finish or stretch, garment area, target hand feel, care process, required width and estimated quantity. Contact UBL with the test information for a fabric-matching discussion.
Bubbling can result from material compatibility, fusing conditions or handling after bonding. Start with the actual shell fabric, interlining model and production settings rather than assuming one universal cause.
If the issue remains, send UBL the fabric details, interlining model, fusing-machine readings, photos and intended care process for technical follow-up. The published H7 table provides a model-specific reference for H7190 only; it is not a universal condition for all fabrics or presses.
See the PA double-dot H7 product page or contact UBL for a sample-matching discussion.
PA and PES describe adhesive systems, not a universal performance ranking. Consider the shell fabric, fusing window, garment end use and intended care process before selecting an adhesive system.
Review the selected model’s published technical data, then run a fusing trial with the actual fabric and intended equipment. Do not assume a wash or dry-cleaning outcome from the adhesive name alone. Confirm the final condition only after the buyer’s own production-representative evaluation.
For model-specific information or a sample-matching discussion, contact UBL with the shell-fabric and garment requirements.
Record the shell-fabric composition, weight, stretch, finish, drape and intended care process. For each garment area, define the structure and hand feel required. Woven fusible interlining and hair canvas may serve different construction approaches; the product family alone does not prove compatibility.
Bond a representative sample using the intended press, allow it to cool flat, then inspect appearance, hand feel, adhesion, shape retention and relevant care performance. Confirm the final combination only after a production-representative evaluation with the actual suit fabric and equipment.

UBL is the name used on the official website of Jiaxing Rainbow (UBL) Interlining Co., Ltd., known in Chinese as 嘉兴瑞柏纺织衬布有限公司. The company manufactures garment interlinings in China, with production locations in Jiashan, Zhejiang, and Wannian, Jiangxi. Its company profile and history describe its development since 1995.
Specify the shell fabric composition, weight, stretch, finish and care process, together with the garment area and required hand feel. Compare the relevant product specifications and test the proposed interlining with the actual fabric. The product family alone does not establish compatibility. For tailored garments, see UBL suit interlining solutions and overcoat interlining solutions.
Individual product pages provide model codes and specification tables. For example, Series 7 twill woven fusible interlining uses PA double-dot coating and lists a recommended fusing temperature of 120–140°C, time of 12–15 seconds and pressure of 1.5–2.5 kg/cm². These are Series 7 conditions; use the relevant product data for other ranges and validate settings on the production machine.
Send the preferred model code or a description of the application, shell fabric details, target weight and width, color, order quantity, delivery destination and washing or dry-cleaning requirements. Include a fabric specification or sample when requesting matching advice. Confirm sample availability, minimum order quantity, customization options and lead time with the sales team for the specific item.
Evaluate the bonded sample for peel strength, shrinkage, hand feel, appearance and adhesive strike-through, then repeat the relevant checks after the intended care process. Request current supporting documents for any product certification or performance requirement that matters to your order, including the applicable product scope.

High moisture content in the fabric or interlining; moisture in damp fabric vaporizes at high temperatures, forming steam bubbles (especially during sealed pressing). It is recommended to ensure the fabric’s moisture regain is ≤ 6% before pressing;
The interlining is not laid flat, resulting in wrinkles or overlaps;
Moving the fabric during pressing causes misalignment of the adhesive layer;
Using a dirty pressing table (residual adhesive residue and dust affect adhesion);
Performing wet-heat treatments such as washing, steaming, or setting after bonding; if the bond strength is insufficient, bubbling is likely to recur;
Fabric is too thick or too dense (e.g., high-count, high-density poplin, coated fabrics), making it difficult for hot-melt adhesive to penetrate;
The fabric contains elastic fibers (e.g., spandex), resulting in a significant difference in heat shrinkage rates between the fabric and the interlining; stress release upon cooling causes bubbling;
The fabric surface has water-repellent finishes, coatings, or oil treatments, which affect the adhesive’s wetting and adhesion;
The hot-melt adhesive granules are too fine, or the melting point is incompatible with the process;
Special post-treatment processes are incompatible with the hot-melt adhesive granules;
Temperature too high: The hot-melt adhesive melts excessively, decomposes, or carbonizes, producing gas that forms bubbles;
Temperature too low: The adhesive does not melt sufficiently, preventing it from penetrating the fabric fibers; the bond is weak, and the material shrinks and bubbles after cooling.
Insufficient pressure → Poor contact between the adhesive and the fabric;
Uneven pressure (e.g., uneven ironing table, deformed pressure plate) → Localized areas fail to bond, creating voids.
Time too short → The adhesive has not fully melted and penetrated;
Time too long → The fabric is overheated, causing moisture to evaporate and form steam bubbles, or the adhesive to age and become brittle.
Moving or folding the fabric before it has cooled sufficiently after bonding → The adhesive layer has not cured; external forces cause micro-bubbles or delamination.
Lightweight nonwoven fusible interlining: Less than 20 g/m²
Medium-weight nonwoven fusible interlining: 20–30 g/m²
Heavy-weight nonwoven interlinings: 30 g/m² and above
Nonwoven interlinings used in apparel are primarily light-weight and medium-weight. For lightweight fabrics (such as silk), light-weight and ultra-light-weight nonwoven interlinings weighing 20 g/m² or less are commonly used.
Based on performance characteristics, they can be classified into non-adhesive, partially adhesive, and fully adhesive types.
Straight interlining—strips cut into bands of varying widths along the warp and weft directions depending on the application.
Bias interlining—including regular bias, narrow bias, and wide bias.
Common specifications include 60°, 45°, 30°, and 12°, with widths similar to those of straight interlining.
A strip-shaped adhesive interlining used to reinforce specific areas of garments. It is used to reinforce and strengthen areas such as the armhole, neckline, hem gusset, sleeve gusset, pocket opening, pocket bottom, and hem edge.
Using a special process, this interfacing is made entirely of hot-melt adhesive in a spider-web-like pattern, resulting in a thin, soft texture. It is sandwiched between two layers of fabric and bonds to both sides when heated, hence the name “double-sided adhesive interfacing” (commonly known as double-sided tape). It is frequently used in piping to provide reinforcement.
