Description

Technical Field

[0001] The invention relates to the technical field of clothing manufacturing, in particular to a wrinkle-effect, non-ironing clothing and a manufacturing method thereof. Background Art

[0002] The advantages of cotton fabrics are that they are soft, hygroscopic and breathable, so they are very suitable for wearing in summer. The advantages of linen fabrics are that they have good hygroscopicity and fast moisture conduction. The clothes made of linen fabrics are not easy to be stuffy after wearing, and they have antibacterial and cool characteristics. At the same time, their rough fiber characteristics make them more wear-resistant and pollution-resistant. In clothing production, pleats are a fabric processing technique often used by designers in clothing design. Generally, the fabrics are kneaded, superimposed or piled in an orderly or random and natural manner, which not only expresses the beauty of clothing and the human body, plays a decorative role, but also reflects the functionality of clothing to the human body. The use of pleats usually makes the fabric more three-dimensional and more varied.

[0003] There are many methods for wrinkle treatment, such as patent documents CN116427118A, CN114197140A, CN118639413A, CN116971178A, etc., which control the temperature, pressure, time, etc. in the production process by hand or press equipment to achieve the wrinkle effect. Specifically, patent document CN116971178A discloses a method for washing pure cotton fabrics with permanent wrinkle effects in multiple styles, including the following steps: liquid treatment: using resin finishing liquid to treat the pure cotton fabric, the resin finishing liquid includes resin, catalyst and fiber protective agent; pre-baking treatment: The pure cotton fabric after the liquid treatment is pre-baked, and the liquid carrying rate of the pure cotton fabric after the pre-baking treatment is controlled to be between 10% and 30%; manual wrinkling treatment: the pure cotton fabric after the pre-baking treatment is manually wrinkled according to the required wrinkling effect; pressing and shaping treatment: the pure cotton fabric after the manual wrinkling treatment is pressed and shaped; high-temperature drying treatment: the pure cotton fabric after the pressing and shaping treatment is subjected to high-temperature drying; washing treatment: the pure cotton fabric after the high-temperature drying treatment is washed; and secondary drying treatment: the pure cotton fabric after the washing treatment is subjected to secondary drying.

[0004] In the wrinkle-free and wrinkle treatment, different process parameters will have a great influence on the wrinkle-free and wrinkle effects. The curing effect after using the above-mentioned wrinkle treatment method is not ideal, and the wrinkles are not easy to shape. In particular, linen fabrics have the characteristics of dryness and rigidity. The wrinkles produced after using linen fabrics to make clothes will return to their original state due to repeated washing, and the molding effect is poor. Summary of the invention

[0044] Example 1

[0045] This embodiment provides a wrinkle-free garment, which is made of machine-washable and wrinkle-free pure cotton fabric through wrinkle-free treatment and wrinkle treatment. The raw material of the pure cotton fabric is 100% cotton, the shrinkage of the pure cotton fabric is within 2.5% in warp and weft, the tear strength is above 20N, and the degree of tearing is controlled within 0.4cm. The pure cotton fabric obtained by the existing method meets the above parameter requirements. The specific production method of the garment is as follows:

[0046] S1. Cut the machine-washable and iron-free pure cotton fabric according to the clothing pattern, and sew it together to obtain a semi-finished garment; the shirt made in this embodiment uses iron-free sewing, and the shrinkage of the sewing is limited to 1%-3%, the breaking strength of the single line is not less than 720cn / 50cm, and the single line skeleton strength is 30-50CN / cm. The seam treatment is recommended to be iron-free sewing, so that there is no exposed seam, which is more neat. The collar / lining is used for the collar part (lapel / stand-up collar), the English position, and the door tube. There is nothing special about cutting. The requirements for the knife edge, upper collar, upper sleeve, and sewing foot depend on the customer's requirements.

[0047] S2, spray the non-ironing finishing liquid and pre-dry. After the clothes are sprayed with the non-ironing finishing liquid, the durable anti-wrinkle performance of the fabric is improved. After washing in the subsequent production process, the friction coefficient between the fabric fibers is reduced, which significantly improves the softness and smoothness of the clothes, making the non-ironing clothes have good anti-wrinkle performance and comfort. The weight ratio of the non-ironing finishing liquid to the clothes is 2:4~1:1.5; the non-ironing finishing liquid is composed of the following components by weight: 170~200 parts of non-ironing resin; 30~40 parts of catalyst; 40~50 parts of fiber protective agent; 40~45 parts of softener; 5~50 parts of water; the pH value of the non-ironing finishing liquid is 4.5~5.5. Specifically, in this embodiment, the ratio of the non-ironing finishing liquid is adjusted according to the weight of the shirts, 40-60 shirts are put into the non-ironing finishing cabinet, and washed in the bidirectional rotating non-ironing finishing cabinet, the rotation speed is 5-30 rpm, and the pressurized atomized finishing liquid is sprayed on the tumbling shirts, the pressure is 0.5-1MPa, so that the shirt liquid rate reaches 65-75%, and the finishing time is 25min; the pre-drying temperature is controlled at 50℃, the time is 16min, and the water content is controlled at 15-20%. If the drying dryness is lower than 80%, that is, the water content is higher than 20%, the liquid will penetrate into the press mold, and the liquid cannot dry quickly, so when the next piece of clothing passes through the press, the drug stains will stick to the clothes, affecting the production process of the clothing.

[0048] S3, performing pleating treatment on the pre-dried clothing according to the required pleating effect.

[0049] The wrinkle treatment is to fix the garment according to the wrinkle effect, and then achieve the predetermined shape after the subsequent pressing and ironing. The wrinkle treatment method is: start from the collar of the shirt, twist it into strips in one direction (clockwise or counterclockwise), and then adjust it to the desired wrinkle effect according to the desired effect, fix it with a cloth strip to maintain the stability of the shirt wrinkles. The cloth strip size: 2cm-3cm width, length: 30cm-40cm, the cloth strip is tied from the time it is tied until the end of the pressing process, 15min-30min.

[0050] S4, press and pre-shape; Pressing is to fix the two ends of the twisted shirt on the press plate. The press uses a non-ironing press without a cover cloth. Both flat and curved ones are possible. The temperature of the ironing table is 100-150℃, the pressure is 0.5-1MPa, and the time is 5-12 seconds. After using the press for multiple presses, the clockwise operation can be completed. The above is a clockwise operation. After the fixed press, turn the shirt counterclockwise and operate it once to complete. During the clockwise and counterclockwise pressing process, the number of presses is determined according to the different styles and wrinkle requirements of the clothing. Generally, it can be completed after 4-8 presses. After the pressing is completed, untie the clothes on the press and release them immediately. There is no need to cool them down. Put them on the hanger and shape them at high temperature.

[0051] S5. Perform high-temperature three-dimensional shaping at 120-150℃ for 5-10 minutes to make the clothes 90% to completely dry. Place the shirts and clothes in a staggered manner in the high-temperature shaping cabinet at 120-150℃, and do not place them close together or stick together.

[0052] S6. Perform iron-free quick freezing cold air finishing. In the iron-free quick freezing cold air finishing equipment, place the clothes in a staggered manner, avoid close contact or sticking, place in a -5-0℃ freezer with extremely fast cooling and gentle wind patting for 6-12 minutes to improve the iron-free feel.

[0053] S7, after washing and finishing, drying, add softener during washing and finishing, wash for 8-10 minutes to improve the feel, wash away the thread ends on the shirt, wash away the unreacted additives, free formaldehyde, etc.; then dry the finished product, low-temperature drying temperature controlled at 80-100℃, time 20-30min, dry until completely dry, and obtain a wrinkle effect and iron-free shirt.

[0054] The inspection of the wrinkle effect of the garment after forming is done by visual assessment and image analysis, using the sample garment as a model, e.g. Figure 1 As shown in (A), the shirt made by the above method is as follows Figure 1 As shown in (B), visual evaluation is performed by experienced staff who visually compare the shirts made by the above method with the samples. Image analysis is to take photos of the wrinkles of the clothing under natural light and at a specific angle, and compare the images. The combination of visual evaluation and image analysis can determine whether the wrinkle effect of the clothing is qualified. If the wrinkles are uniform and have a high degree of similarity, it is qualified. If the similarity is low and the wrinkles are uneven, it is unqualified. If the wrinkles on the upper body are not clear and there are wrinkles on the lower body, it is also unqualified. After comparison with the sample, it is found that the wrinkle effect of the shirt made by the above method is qualified, the tear strength of the clothing fabric is more than 10N, and the degree of tearing is controlled within 0.6cm. The qualified shirts are sent for inspection, and the results are as follows: Figure 2 As shown, from the results it can be seen that the shirt meets the appearance standards after washing.

[0055] The above-mentioned shirt was washed 5 times, each time for 55 minutes according to the standard washing method, and dried at 55-70℃. After 5 washes, the clear wrinkle effect was still retained. Figure 3 , Figure 4 .

[0056] Example 2

[0057] This embodiment provides a shirt with wrinkle effect and no ironing. The manufacturing method of the shirt is similar to that of the embodiment 1, except that the wrinkle processing method in step S3 is different. The wrinkle processing in this embodiment adopts a manual processing method, specifically: 0.4 The first person A grabs the left and right ends of the shirt collar with both hands, and the other person B grabs the left and right ends of the shirt hem with both hands, pinches the folds towards the middle, and pinches the shirt together at both ends of the hem, and then rotates clockwise (counterclockwise) until the desired wrinkle effect is adjusted. At the same time, A grabs the left and right ends of the shirt collar with both hands and twists the shirt with B, slowly moving the hands closer until the shirt collar is twisted together, and then fixes the two ends of the twisted shirt on the press plate for subsequent pressing and pre-forming.

[0058] After comparing with the sample, it is found that the wrinkle effect of the shirt made by the above method is qualified. Figure 5 shown.

[0059] Test Example 1

[0060] This test example provides a wrinkle-free shirt. The manufacturing method of the shirt is similar to that of Example 1. The shirt is made of pure cotton fabric through wrinkle-free treatment and wrinkle treatment. The difference is that the pure cotton fabric used in this example is not treated with liquid ammonia. The other manufacturing steps are the same as those of Example 1 to obtain a shirt.

[0061] Compare the shirt in this test example with the sample, such as Figure 6 The wrinkle effect is unqualified, the wrinkle shaping effect is weak, and the shirt surface will have bumpy bubbles after washing. This is because liquid ammonia treatment will make the fabric softer, cause less damage to the fiber, and the fabric will not become hard after multiple washings. The pure cotton fabric used in the shirt of this embodiment has not been treated with liquid ammonia, and the fabric is relatively hard. After the non-ironing treatment and wrinkle treatment using the above method, the surface wrinkles will not be formed and the stability is not good.

[0062] Test Example 2

[0063] In order to test the effect of the liquid carrying rate on the wrinkle effect of the garment after spraying the non-ironing finishing liquid in step S2, the fabric and production method of Example 1 were used, except that the liquid carrying rate after spraying the non-ironing finishing liquid was different. The conditions of different test examples were as follows:

[0064] Test Example 2-1: After spraying the permanent iron finishing liquid, the liquid carrying rate was 69%;

[0065] Test Example 2-2: After spraying the permanent iron finishing liquid, the liquid carrying rate was 79%;

[0066] Test Example 2-3: After spraying the permanent iron finishing liquid, the liquid carrying rate was 62%;

[0067] The shirt obtained in the above test example was tested. During the test, the test method for tear strength test was GB / T3917.2-2009 trouser shape method, and the test method for seam slippage degree test was GB / T 21294-2014, 9.2.1, load 100N. The fabric picture of the shirt in test example 2-1 is as follows: Figure 7 The test results are shown in Table 1, where the tear strength data is the average value of three sets of data.

[0068] Table 1 Effect of different liquid carrying rates on clothing performance

[0069]

[0070] In the clothing performance test, if the warp and weft strength of the clothing fabric is less than 10N or the seam tear test data is less than 0.6cm, it is considered that the data does not meet the standard, otherwise it is within the standard range. Generally speaking, the warp and weft tear of the fabric is greater than 10N to greater than 32N, and the fabric tear data is less than 0.2-1.6cm. From the data in the above table, it can be seen that when the liquid carrying rate of the clothing after spraying the non-ironing finishing liquid is 69%, the tear strength, seam tear degree and wrinkle effect of the clothing all meet the standard value requirements. When the liquid-carrying rate after spraying is high (greater than 75%), i.e. 79%, the tearing strength and the degree of cracking of the fabric are relatively weakened, which makes the fabric easy to tear after washing. During the production process, it is found that the liquid-carrying rate is too high and the clothes will become hard when dried to the normal dryness of 85%, which affects the touch of the clothes; when the liquid-carrying rate after spraying is low (less than 65%), i.e. 62%, the fabric forming effect is not good, the wrinkles are not clear, and the wrinkles are unqualified. Therefore, after spraying the non-ironing finishing liquid, the liquid-carrying rate of the clothes is 65-75%, which is the best choice.

[0071] Test Example 3

[0072] In order to test the effect of the finishing time of the non-ironing finishing liquid sprayed on the clothing in step S2 on the wrinkle effect, the fabric and production method of Example 1 are used, and the clothing liquid carrying rate is 69%. The difference is that the finishing time is different, and the finishing time is 20min and 30min respectively. The clothing is observed after finishing to check the penetration of the non-ironing finishing liquid. When the clothing liquid carrying rate is 69% after spraying the non-ironing finishing liquid, if the finishing time is 30min, the penetration of the non-ironing finishing liquid is uniform; if the finishing time is 20min, the clothing has uneven penetration of the non-ironing finishing liquid, and some parts are prone to more liquid, which will lead to a reduction in the strength and degree of cracking of the fabric, affect the three-dimensional degree of the wrinkles, unclear wrinkles, unqualified wrinkles, and cause obvious wrinkles in some parts. It is easy to break. When spraying the non-ironing finishing liquid, the finishing time should be reasonably selected within the range of 20-40min according to the clothing liquid carrying rate.

[0073] Test Example 4

[0074] In order to test the effect of each pressing time on the wrinkle effect during the pressing process in step S4, the fabric and production method of Example 1 were used, the temperature of the ironing table was 120°C, and the pressure was 0.5-1MPa. The difference was that the pressing time was different each time. The conditions of different test examples were as follows:

[0075] Test Example 4-1: Each pressing time is 12 seconds, and pressing is performed 3 times in clockwise and counterclockwise directions respectively;

[0076] Test Example 4-2: Each pressing time is 14 seconds, and pressing is performed 3 times in clockwise and counterclockwise directions respectively;

[0077] Test Example 4-3: Each pressing time is 16 seconds, and pressing is performed 3 times in clockwise and counterclockwise directions respectively;

[0078] Test Example 4-4: Each pressing time is 4 seconds, and pressing is performed 5 times in clockwise and counterclockwise directions respectively;

[0079] The tear strength of the shirt obtained in the above test example was tested. The test results are shown in Table 2 below. The tear strength data under different conditions are the average values ​​of three groups of data.

[0080] Table 2 Effect of different liquid carrying rates on clothing performance

[0081]

[0082] From the data in the above table, we can see that when the pressing time is 12s each time, the tear strength of the clothing meets the standard value requirements. When the pressing time is greater than 12s each time, the tear strength of the clothing fabric is weakened, and the fabric that has been in contact with the pressing machine for a long time will become brittle and easily form yellow patches; when the pressing time is less than 5s each time, the wrinkle shaping effect is unstable, the fabric will have a certain elasticity, and the wrinkles will disappear easily. At the same time, the pressing time was tested to be 12s each time, and the clockwise and counterclockwise pressing methods were pressed 2 times, 3 times, and 5 times respectively. If the pressing times are too few, the pressing effect will be unclear, and if the pressing times are too many, the pressing will be too dense and broken, the wrinkle lines will be messy, and the wrinkles will be unqualified. After many adjustments, it was finally found that the pressing temperature of 110 degrees to 130 degrees, the pressing time of 5-12 seconds each time, and the total pressing times of 4-8 times in the pressing process are the best choices, which can ensure the appearance of the wrinkles and the quality of the clothing.

[0083] Test Example 5

[0084] In order to test the influence of the high temperature setting condition on the wrinkle effect in step S5, the fabric and the manufacturing method of Example 1 were used, the difference being the temperature and time of the high temperature setting. The conditions of different test examples were as follows:

[0085] Test Example 5-1: Setting temperature 110°C, time 10 minutes;

[0086] Test Example 5-2: Setting temperature 120°C, time 10 minutes;

[0087] Test Example 5-3: Setting temperature 130°C, time 5 minutes;

[0088] Test Example 5-4: Setting temperature 130°C, time 15 minutes;

[0089] Test Example 5-5: Setting temperature 140 or 150°C, time 10 minutes;

[0090] The shirt obtained in the above test example was tested.

[0092]

[0093] From the data in the above table, we can see that if the setting temperature exceeds 130℃ and the time exceeds 10 minutes, the clothes will become brittle, and the strength and cracking degree will deteriorate. On the contrary, if the setting temperature is 110℃ and the time is less than 5 minutes, the setting effect of the wrinkles on the finished clothes will become weaker, and the wrinkles cannot be clear and three-dimensional after washing. When the setting temperature is as high as 140℃, the clothes will become brittle, and the strength and cracking degree will deteriorate. The final data obtained is that 110-130℃ is the most appropriate.
