With the development of the times and the continuous improvement of people's living standards, the requirements for clothing have also been continuously improved. It is not limited to warmth, durability, and new requirements have been put forward for comfort, aesthetics, and functionality. The fabric is prone to fluffing and pilling during wearing. This phenomenon not only deteriorates the appearance and feel of the fabric, but also wears the fabric and reduces the performance of the fabric. Fabric pilling process Factors Affecting Pilling Factors affecting fabric pilling are mainly the effects of fiber properties, yarn, fabric structure, dyeing and finishing process, etc. 1. Fiber properties Fiber strength Fibers with high strength, large elongation, high resistance to repeated bending, and strong wear resistance are not easy to be broken or shed when rubbed, but will further entangle with the surrounding hair clumps and hair balls to form larger balls. However, the fiber strength is low, and the formed hair balls are easy to fall off from the surface of the fabric after friction. Therefore, the fiber strength is high and easy to pill. Fiber length Short fibers are easier to pill than long fibers, and long fibers are less prone to pilling than short fibers. The frictional resistance of long fibers in the yarn is greater than that of short fibers, and it is not easy to be drawn out from the yarn. In the same number of fiber cross-sections, the end of the long fiber exposed to the surface of the yarn is less than that of the short fiber, and the chance of being rubbed by external force is small. Polyester filaments have high strength and are not easy to wear and break when subjected to mechanical external force, and polyester filament fabrics are not easy to pilling. Fiber fineness For the same raw materials, thin fibers are easier to pill than thick fibers. The thicker the fibers, the greater the bending stiffness. Friction between fibers The friction between the fibers is large, the fibers are not easy to slide, and it is not easy to pilling. Fiber blends are prone to pilling Especially the blended fabrics of chemical fibers and wool, cotton, and regenerated cellulose fibers are prone to pilling, because the chemical fiber fibers are relatively strong ball fibers and are not easy to fall off. Fiber cross-sectional shape The fiber with special-shaped cross-section has high bending rigidity, is not easy to bend and entangle, and has a low probability of relative contact and friction, is not easy to pull out and entangle, and is not easy to produce pilling. Fiber crimp The more crimped the fiber is, the less likely the fiber is to stretch when twisting, and the fiber is easy to loosen and slip during the friction process, forming plush on the surface of the yarn. Therefore, the better the curl of the fiber, the easier it is to pilling. 2. Yarn The main factors that affect the pilling of fabrics are yarn hairiness and wear resistance, which involve ...

In the daily process of dressing, the most troublesome thing is picking up the clothes when I am anxious to go out in the morning. I often have this trouble. I don't know if you will. Ironing is time-consuming when it is too late. Wrinkle of clothing fabric directly affects its beauty and wearing effect. So, why do clothes wrinkle, and how should we deal with wrinkle prevention in daily life? So what exactly causes the fabric to wrinkle? Wrinkling: The phenomenon of creases or wrinkles caused by external forces such as rubbing, squeezing, twisting, and twisting of fabrics in the process of wearing and washing care is called wrinkling. 1. Micro perspective Under the action of external force, the fibers constituting the fabric are deformed. After the external force is removed, the deformation cannot disappear, cannot be restored to its original state, or can only be partially restored. 2. Macro perspective Wrinkle formation can be divided into two stages: crease generation and crease recovery after external force removal. 1) Crease generation: Under the action of external force, the fabric is bent and deformed. Since the external force is far greater than the resistance of the fabric due to bending, the fabric is forced to bend and deform, that is, beyond the bending elastic deformation range of the fabric, yielding deformation. 2) Crease recovery After the external force is removed, the crease bending of the fabric begins to recover under the elastic recovery force generated by the internal stress, that is, the angle of crease recovery starts to increase. With the extension of time, the crease recovery angle increases, and its change is similar to the material creep law. In this process, in addition to the elastic recovery force of the fabric, it is also affected by the friction resistance, which is generated by the relative slippage between the yarns and between the fibers of the yarn, and its direction is opposite to the elastic recovery force. When the elastic recovery force and friction resistance of the fabric are balanced, the fabric reaches the maximum recovery effect. At this time, the fabric folding angle is the crease recovery angle of the fabric. Crease resistance of fabrics: The ability of fabric to resist wrinkling and deformation is called wrinkle resistance, that is, the fabric can be folded and pressurized under specified conditions. After the load is removed, the crease of the fabric can return to the original state to a certain extent, which is also called the crease recovery of the fabric. It can be seen from the causes of fabric wrinkling that to overcome the shortcomings of fabric wrinkling, it is necessary to reduce the opportunity for fiber to generate relative displacement between macromolecules under external force, or prevent the formation of hydrogen bonds at new positions when macromolecules have relative displacement, so that macromolecules can quickly return to their original positions after the removal of external fo...

The autumn wind is coming, and summer is slipping away. Summer is a season easy to sweat. After a good sweat, it can make us feel happy, but at the same time, many people are worried. After sweating, clothes are easy to fade. In fact, this is likely to be caused by the unqualified color fastness of your clothes to perspiration. Colour fastness to perspiration There are millions of effective sweat glands on human skin, and the forehead, armpits, chest, back and palms sweat more; therefore, clothes often worn in summer, such as shirts, T-shirts and other clothes, will fade seriously in these parts. As we all know, the composition of human sweat is complex, the main component of which is salt, which varies from person to person. Sweat is acidic and alkaline. The short-term contact of textiles with sweat may have little effect on its color fastness, but long-term contact with the skin and sweat will have a greater impact on some dyes. Clothing with unqualified dye fastness is easy to transfer dyes from textiles to human skin through sweat, etc. The molecules of dyes and heavy metal ions may be absorbed by the human body through the skin and endanger health. The color fastness to perspiration reflects the discoloration of the textile itself and the staining of the lining fabric under the combined action of pressure and temperature in different test solutions containing histidine. How to improve the color fastness to perspiration Improve the color fastness of the fabric to perspiration: 1. The most important way is to choose dyes reasonably, especially dyes with high fixation rate and good stability should be used. 2. Reasonably formulate and control the dyeing process, strengthen the fixing conditions, and form a covalent bond with high stability, so that the dye can be fully fixed. For example, when dyeing dyes with poor reactivity, a catalyst can be used, or an appropriate fixing agent can be used, or the color can be fixed at a relatively high temperature.

Clothes stained during washing or soaking? I believe that everyone is familiar with this situation, and many people should have encountered such embarrassing things. This is due to the mixed washing of dark and light-colored clothes, the fading of dark-colored clothes and dyeing on light-colored clothes, resulting in staining of light-colored clothes, or the mutual staining of dark and light colors on a piece of clothing after washing. In response to this phenomenon, there is a professional name in textiles: splicing and mutual dyeing. Test methods for testing the interdyeing of textiles by splicing, namely the washing method and the soaking method. The washing method The sample is placed in the specified washing solution, mechanically stirred according to the specified bath ratio, time and temperature, then washed and dried, and the staining of the light-colored sample is evaluated with a staining gray card or an instrument. The soaking method The sample is placed in the specified washing solution, and after treatment, it is placed between two flat plates with a specified pressure in the test device. After cleaning and drying, the staining of the light-colored sample is evaluated with Gray scale for color staining or an instrument. Sample preparation: 1. The sample is a ready-made garment. Cut a piece of dark and light-colored fabrics, 4×10cm, and sew them along the short side to form a combined sample. 2. Weigh the sample to the nearest 0.01g. 3. Add detergent according to the sample weight. The sampling and soap solution configuration of the two methods are the same, the only difference is the test equipment and operating procedures. Test Instruments The washing method: Wash Colour Fastness Tester The soaking method: Precision Drying Oven Operating procedure The washing method 1. Put the sample and test solution into the container 2. Put the container into the machine, set the temperature to 40 degrees, and test it for 30 minutes. 3. Take out the sample and rinse it with running water until it is clean. The soaking method 1. Put the sample and test solution into the container, press and move from time to time to completely soak the sample, take out the sample and place it on the Perspiration Tester, and apply a pressure of 5000g. 2. Put the loaded sample into the Precision Drying Oven, the temperature is 37 degrees, for 4 hours, take out the combined sample, and rinse it with running water until it is clean. The test temperature of the washing method is 3°C higher than that of the soaking method. In terms of test time, the washing method requires 30 minutes and the soaking method is 4H. After the test is completed, after rinsing the test, it is necessary to absorb excess water with filter paper and hang it to dry. The samples tested by the two methods are evaluated by Gray scale for color staining. From the test results, the stain level of the soaking method is much more serious than that of the washing method. Color Fastness Test Machines abo...

In the process of wearing and using fabrics, different degrees of pilling will occur. So how can we reduce the pilling of our fabrics? Spinning process During the spinning process, the fibers in the twisting triangle area undergo repeated internal and external transfer due to uneven force, causing the head end, tail end or middle part of most fibers to protrude from the yarn body, forming hairiness. In order to reduce the hairiness, the textile mill rationally mixes cotton, optimizes the process, adopts advanced textile technology according to its own conditions, and tries to control the occurrence of hairiness within the scope of its ability. Weaving process The organizational structure of knitted fabrics has a great influence on pilling, and the tight organization is less prone to pilling than the loose organization. Dyeing and finishing process Singeing: Singeing is a great way to reduce hairiness and reduce pilling. Adjustment of technical parameters: After the dyeing and finishing technology is determined, parameters such as bath ratio time can be adjusted appropriately, for example, the bath ratio can be appropriately increased or the technical curve can be improved to shorten the time. Use of auxiliaries: Anti-pilling agents can be added during the bleaching process. The softener is added during the dyeing process to reduce the mixed friction between the yarns and between the fabric and the dyeing machine, and at the same time, it can control the leakage of the fibers from the end of the yarn, thereby reducing the chance of pilling. Hairiness appressing method: The hairiness appressing method is to use mechanical and physical and chemical methods to make the hairiness tightly adhere to the surface of the fabric, so as to reduce feathers and reduce pilling. Specifically, the use of resin auxiliaries or chemical adhesives, through rolling, makes the hairiness lodged and fixed on the surface of the yarn. Through the above methods, the pilling can be improved to a certain extent. Reducing pilling is a systematic project, and it is recommended to take comprehensive measures in the production process of fiber production, spinning, weaving, dyeing and finishing.

Fabrics are products made of yarn (thread) or fiber, mainly including woven fabrics, knitted fabrics and nonwoven fabrics. Woven fabrics are products made of two groups of mutually perpendicular yarns (threads) interwoven on the loom, such as common plain cloth, gabardine, khaki, satin, etc. The yarn arranged along the length of the fabric is called warp, and the yarn arranged along the width of the fabric is called weft. By changing the raw materials, thickness and organizational structure of the yarn or using different colored yarns to cooperate with each other, different warp and weft yarns are interwoven with each other, and fabrics of different styles and uses can be woven. These fabrics can be divided into clothing fabrics, decorative fabrics and industrial fabrics. A. Classification of woven fabrics for clothing Woven fabrics for clothing are usually classified according to whether the raw material yarn is dyed or not, fabric pattern and width. 1. According to the type of raw materials (1) Pure textile fabrics: The warp and weft yarns are all fabrics made of the same fiber raw material, such as cotton fabrics, linen fabrics, wool fabrics, silk fabrics, etc. (2) Blended fabric: warp and weft yarns are fabrics made of yarns mixed with two or more fibers, such as polyester / cotton fabrics, wool / polyester fabrics, polyester / linen fabrics, wool / polyester / nitrile fabrics and medium length fabrics. (3) Interwoven fabrics: fabrics made of different raw material yarns for warp and weft, such as silk-wool interlacing, cotton and viscose filament interlacing, silk and viscose filament interlacing and other interwoven fabrics. (4) Interlaced fabric: The warp and weft yarns are woven from two or more different raw materials combined with synthetic strands. 2. Classification according to whether the yarn is dyed or not (1) Natural color fabric: the yarn is processed into fabric without bleaching and dyeing, which is directly sold or processed into finished products after dyeing and printing. (2) Yarn dyed fabric: a fabric made of bleached and dyed yarn. 3. Classification by fabric pattern (1) Plain fabrics: fabrics without patterns, such as various plain fabrics, twill fabrics, satin fabrics, etc. (2) Small patterned fabric: the pattern fabric with small area is formed on the fabric through the change of fabric structure, such as various tweeds. (3) Jacquard fabrics: fabrics with a wide range of patterns formed by controlling a single warp, such as floral satin. 4. According to the width of fabric, it can be divided into wide fabric, narrow fabric and belt fabric. B. Classification of decorative woven fabrics Decorative fabrics are available in a wide variety, usually divided by application. (1) Bedding: such as quilt cover, quilt cover, bed sheet, towel quilt, pillow towel, etc. (2) Furniture cloth: such as sofa cover, chair cover, etc. (3) Indoor articles: such as curtain cloth, wall covering, carpet, curtain fabric, etc. (4) Dining room and ...

Nov 18, 2024Clothes may be damaged to varying degrees during the washing process, such as the following situations. These situations can remind everyone to control the production process to avoid similar situations. 1. Changes in printed clothes after washing: Color bleeding, Fading, Loss of print integrity, Rubber deformation & aging 2. Fabric color transfer after washing During the washing process, fabrics of different colors penetrate each other, causing color confusion and color blending. This usually happens more often with clothes with sharp color contrasts. For example, the following situations all show obvious color blending after washing. 3. Clothes with accessories are also prone to varying degrees of damage after washing: 1) Accessory damage • Deformation • Fading • Surface wear 2) Problems with the connection between accessories and clothing • Looseness • Falling off 3) Problems with the garment itself • Deformation • Stain transfer or stain transfer These situations are the nodes that fabric and clothing manufacturers need to focus on during the production process.

Jun 27, 2024The lasting vividness of clothing colors makes textiles visually attractive and expressive, so maintaining the color fastness of clothing is of vital importance. Color fastness refers to the ability of textile materials to maintain their original color under various conditions, including washing, friction, light, sweat, etc. Color fastness testing can help manufacturers screen and evaluate the quality and life of products. Good color fastness means that textiles are not easy to fade during post-processing or use; poor color fastness means that the color will fade, slightly discolor, or stain, causing a lot of trouble. Several common color fastness of textiles: 1. Light Fastness Sunlight fastness refers to the discoloration of colored fabrics under the influence of sunlight. It is mainly measured by simulating the fading degree of the sample after exposure to sunlight, and then comparing and rating it with the standard color sample to evaluate the quality of the fabric according to different grades. Fabrics with poor sunlight fastness should not be exposed to the sun for a long time. It is recommended to dry them in a ventilated place. 2. Sublimation fastness Sublimation fastness refers to the degree of sublimation that occurs when dyed fabrics are stored. Sublimation fastness uses a gray grading scale to assess the discoloration, fading, and staining of white cloth after dry heat pressing. There are 5 levels, with 1 being the worst and 5 being the best. Generally, 3-4 levels are required to meet the needs of wearing. 3. Rubbing Fastness Rubbing Fastness refers to the degree of color fading of dyed fabrics after rubbing, which can be divided into dry friction and wet friction. The degree of color fastness to friction is evaluated based on the degree of staining of white cloth. There are 5 levels in total. The larger the value, the better the rubbing fastness. 4. Perspiration fastness Perspiration fastness refers to the degree of color fading of dyed fabrics after being soaked in sweat. Since the composition of artificially prepared sweat is different, perspiration fastness is generally tested separately and combined with other color fastness. 5. Washing fastness Washing color fastness refers to the degree of color change of dyed fabrics after washing with detergent. Usually, a gray grading sample card is used as the evaluation standard, that is, the color difference between the original sample and the sample after fading is used for evaluation. Fabrics with poor washing fastness should be dry washed. If wet washing is performed, attention should be paid to the washing conditions, such as the washing temperature should not be too high and the washing time should not be too long.
