Precautions for Operating Automatic Fabric Shrinkage Tester
-
Please strictly adhere to the following scopes when setting parameters on this machine. Exceeding the scopes will invalidate the settings. When setting the water level, the user can only enter (10 or 13) cm, otherwise, it is invalid. Set the water temperature to the normal range, from the operating temperature to 99°C. If not, it’s invalid. When setting the washing, rinsing, and cooling times, the setting time can be 0 to 99 minutes.
-
Make sure the fabric shrinkage machine is on a smooth, solid surface. This will prevent tilting and ensure it operates properly.
-
The inlet pipe must be secured. This prevents water from seeping into the electrical parts. The water could leak and damage them.
-
You need to remove fabric fibers from the filter often. This keeps the drainage pipe clear.
-
Do not open the front glass door when the machine is running. Also, do not open it when the barrel has water. This is to avoid leaks and burns.
The test procedure for dimensional stability of textiles
A complete test procedure consists of a washing process and a drying process. So according to the purpose of fiber and fabric, washing can be divided into two parts: household washing and commercial washing. In general, clothes are generally washed using the home washing procedure. The main test procedures are as follows.
1 Make a specimen according to the standard and also mark it in the direction of length and width.
2 Prepare the automatic shrinkage washer or the fabric shrinkage test machine and drying equipment, then select the appropriate Fabric Shrinkage Test Methods such as AATCC 135, ISO 5077, and ISO 6330.
3 Pre-conditioning the specimen, then starting the test, and finally calculating the dimensional change.
Influencing factors for washing dimensional stability tests
You may be familiar with the clothes shrinking in the washing machine. The main influencing factors are the water temperature, the degree of agitation during washing, the washing time, and the drying method. The main manifestations are as follows.
Firstly, the higher the water temperature, the greater the shrinkage of the fabric.
Secondly, the longer the washing time, the greater the shrinkage of the fabric.
Thirdly, the greater the rotating speed of the automatic shrinkage washer, the greater the shrinkage of the fabric.
In addition, among the drying methods, the shrinkage of the fabric is most significant when tumbling drying, while the shrinkage of the fabric is most minor when flat pressing.

Automatic Shrinkage Test Method
Test apparatus:
- Automatic shrinkage washer
- ECE non-phosphate detergent
- ICE non-phosphate detergent
- Drying oven
- Scale
- Sewing thread
- Needle
- Pen
- Fabric
Test piece preparation:
Choosing the smooth test piece, the size of it should be greater than 500mm*500mm. Or we can choose the length of the full width at least 500mm if the breath is less than 500mm. Three pairs of tags are marked along the warp and weft of the test piece, the distance between two tags should greater than 350mm, and the distance between the tag and the edge should greater than 50mm. On occasion, we can choose the test piece with 250mm*250mm, three pairs of tags are also marked along the warp and weft of the test piece, the distance between two tags is 200mm.
Test procedure:
- Pouring the detergent into the shrinkage washer, ECE non-phosphate detergent (without fluorescent brightener) and ICE nonphosphate detergent (with fluorescent brightener) are suitable for both type A and type B shrinkage washer.
- Putting the prepared test piece and dummy into the shrinkage washer, and selecting temperature, water-level and time and putting the prepared test piece and dummy into the shrinkage washer.
- After that, we can make the test piece dry in one of the following manners.
- Hang dry. We spread and hang the test piece on the laundry rack to dry it at room temperature.
- Drip dry. We spread and hang the test piece on the laundry rack to dry it at room temperature without spin.
- Lay flat. We flatten the test piece on the horizontal plate smoothly by hand (without any force of spread and twist).
- Flat pressing. We flatten the test piece on the press plate, set the suitable temperature and time, and record the temperature and press.
- Tumble dry. We can dry the test piece by cylinder dryer, and choose the low temperature for heat-sensitive fiber.
- Oven drying. We flatten the test piece on the screen mesh of the drying oven, and set the temperature of 60±5℃ (without any force of spread and twist).
Test measurement:
- The test piece is put on the table without any force of spread, and the shrinkage rate will be got by the ratio scale directly.
- The shrinkage rate can also be calculated from the length of three pairs warp and weft (accurate to 1mm) by the graduated scale, and put the average into the formula.
Test formula:
DC=（B-A）/A*100%
In the equation:
DC - The rate of dimensional change
A - The size before washing
B - The size after washing
Yes, Fully Automatic Shrinkage Tester TF176 belongs to this type.
What is fabric shrinkage?
A: The shrinkage rate of textiles refers to the percentage of fabric shrinkage after washing or soaking.
The smallest shrinkage rate is synthetic fibres and mixed textiles, followed by woollen fabrics, linen fabrics, cotton fabrics in the middle, silk fabrics shrinkage is larger, while the largest is viscose fibres, man-made cotton, man-made wool type fabrics.
What is pre-shrinkage?
Fabric pre-shrinkage is a finish that prevents fabric from shrinking. Shrinkage is the actual reduction in fabric size. The key difference is that pre-shrinking stops shrinkage from happening, while shrinkage measures the actual loss of size.
What do the values '4N' stand for in the test?
The number "4" indicates the temperature, which corresponds to 40℃. The letter "N" signifies the washing action; for instance, "N" stands for normal agitation, "M" represents gentle agitation, "G" also denotes gentle agitation, and "H" indicates imitation hand wash.
What are the shrinkage rates for different fabrics?
Typical shrinkage rates for fabrics are:
- Cotton: 4%–10%
- Synthetic Fabrics: 4%–8%
- Cotton-Polyester Blends: 3.5%–5.5%
- Unbleached White Cloth: 3%
- Woolen Blue Cloth: 3%–4%
- Poplin: 3%–4.5%
- Patterned Fabrics: 3%–3.5%
- Twill Fabric: 4%
- Workwear Fabric: 10%
- Rayon (Artificial Cotton): 10%
Which Instrument can be used to calculate fabric’s shrinkage rate?
The SmartShrink Fabric Shrinkage Rate Tester determines many fabric shrinkage test results in just 5 seconds.
What are the factors affecting shrinkage rates?
Raw Materials: The shrinkage rate varies with the type of raw materials used in the fabric. Generally, fibers with high moisture absorption will expand when soaked in water, increasing their diameter and shortening their length, leading to greater shrinkage. For example, viscose fibers can absorb up to 13% moisture, while synthetic fibers, which have poor moisture absorption, exhibit lower shrinkage rates.
Fabric Density: The density of the fabric affects its shrinkage rate. If the density in the warp and weft directions is similar, the shrinkage rates in these directions will also be similar. Fabrics with high warp density will shrink more in the warp direction, while fabrics with higher weft density will shrink more in the weft direction.
Yarn Thickness: The thickness of the yarn affects shrinkage rates. Fabrics made with thicker yarns generally exhibit greater shrinkage, while fabrics with finer yarns have lower shrinkage rates.
Production Process: Different fabric production processes result in different shrinkage rates. Fabrics that are stretched multiple times during weaving and finishing, and those subjected to higher tension, tend to have greater shrinkage, while those processed with less tension show lower shrinkage.
Fiber Composition: Natural plant fibers (such as cotton and linen) and regenerated plant fibers (such as viscose) absorb moisture and expand more easily compared to synthetic fibers (such as polyester and acrylic), leading to higher shrinkage rates.
Fabric Structure: Generally, woven fabrics have better dimensional stability than knitted fabrics. High-density fabrics are more stable than low-density ones. Among woven fabrics, plain weave typically has lower shrinkage than flannel, while in knitted fabrics, plain knit has lower shrinkage compared to ribbed knit.
Production and Processing: During dyeing, printing, and finishing processes, fabrics are inevitably stretched by machines, introducing tension into the fabric. When the fabric encounters water, this tension is often released, leading to noticeable shrinkage after washing.
Washing and Care: Washing, drying, and ironing all impact fabric shrinkage. For instance, hand-washed samples generally maintain their dimensions better than machine-washed samples. Washing temperature also affects dimensional stability; higher temperatures usually result in greater shrinkage. Additionally, the drying method can significantly influence the fabric's shrinkage rate.
