Description
Technical Field
The invention relates to the technical field of washing, in particular to a washing bag mesh bag capable of preventing discoloration and a washing bag.
Background
For white or light-colored clothes, people often have the trouble that the color changes after one time of washing, or after the clothes are washed and worn for many times, the whiteness of the white clothes gradually decreases until the white clothes are obviously grayed or are obviously stained, or for dark-colored clothes, the phenomenon of obvious hair sticking appears after washing. In response to the commonly encountered problem, the inventor has conducted a research on actual household washing tests of consumers and scientifically and statistically analyzed a large number of research results to find out that the phenomenon is caused by a large number of factors, wherein the shuffling of clothes with different colors is the most important influencing factor.
Modern life is vivid and fast, and in order to save washing time and water and electricity, most consumers are used to put clothes with different colors into the washing machine for washing at the same time. When the clothes are shuffled, the washed clothes generally have dye shedding and fiber shedding at the same time, especially cotton clothes, and the shed dye and fiber can stain other clothes to change the color of the clothes. The washed clothes have different materials and colors, and the staining degree caused by the dropping of dyes and fibers is different. If the color fastness of the clothes is good and no obvious dye falling condition exists, the fallen colored fibers have dominant influence on the contamination of white or light-colored clothes; if the clothes are white and light, the fallen fibers will stain the clothes with dark colors, which greatly affects the appearance of the clothes.
The problem of staining caused by dye shedding can be improved by adding an anti-cross-color additive into a detergent, or using a laundry piece or a laundry block with anti-cross-color, or using a laundry bag with a color absorbing function. In the prior art, for example, CN106350288A and CN108559659A are methods for improving dye cross dyeing in a washing process by adding an anti-cross dyeing auxiliary agent into a component of a laundry detergent; for example, CN107629895A and CN107268177A are prepared into laundry tablets by blending cation modified fibers and other fibers, so that the laundry tablets have the function of absorbing dye, thereby achieving the effect of preventing cross dyeing; for example, CN107699399A can reduce the dye contamination in the washing and rinsing stages by fixing the anti-cross color block which can slowly release the anti-cross color auxiliary agent in the washing machine; for example, CN107476034A and CN107476035A both absorb the dye in the washing solution by disposing an absorption layer in the conventional laundry bag, thereby preventing the color cross-linking problem when washing the clothes, but the laundry bag needs to be discarded after one washing and cannot be reused.
The existing methods only aim at the problem of dye shedding contamination, and cannot solve the problem of color change caused by shedding and contamination of colored/white fibers. Meanwhile, tests show that white or light-colored clothes are put into the washing bag, so that the color of the clothes in the bag is not protected, and the contamination of the clothes in the bag by colored fibers can be increased, so that the color change degree of the clothes is increased, and a new solution is required to be found to solve the problem of the contamination of the clothes during the shuffling process.

Detailed Description
The present invention will be described in further detail with reference to specific examples. The starting materials, reagents or apparatus used in the examples and comparative examples were obtained from conventional commercial sources or by known existing methods, unless otherwise specified. Unless otherwise indicated, the testing or testing methods are conventional in the art.
The test methods for the pore size distribution and the average pore size of the mesh bag of the laundry bag are as follows: the determination is carried out according to GB/T32361-2015 separation membrane pore size test method bubble point and average flow method. Wherein the pore distribution is the percentage of gas flow through a specified pore size range over the total pore flow. The pore diameter at average flow, i.e. the average pore diameter, is calculated from the pressure at which the measured wet membrane gas flow corresponds to half the dry membrane gas flow. The specific test method is as follows: the pore size of the fabric was measured using a capillary flow microfiltration membrane pore size analyzer and the sample was placed in a sample chamber and wetted with deionized water having a surface tension of 72.8dynes/cm or GQ16 wetting agent having a surface tension of 16.0 dynes/cm. The diameter of a bottom clamp of the sample is 30mm, and an O-shaped ring, a supporting net, the sample and the O-shaped ring are sequentially placed in the sample pool. The samples were actually tested as circular areas of 10mm diameter. The wet curve is tested in the testing process, and the dry curve is automatically tested after the holes are completely opened. The pore size, pore size distribution, and average pore size can then be calculated. For example, the average pore diameter can be calculated by substituting the pressure at the intersection of the semi-dry curve and the wet curve into a formula.
Regarding the total coverage tightness of the fabric, the calculation is made with reference to "fabric organization and structure" (consider flat, fabric organization and structure, tokyo university press, 2010), as shown in formula (1):
Ef＝Ej+Ew-EjEw (1)
in the formula (1), Ef: total cover tautness,%; ej: warp direction cover tightness,%; ew: degree of coverage,%, of the weft cover.
The degree of warp cover tightness can be calculated by equation (2):
in the formula (2), Ej: warp direction cover tightness,%; y: the yarn diameter coefficient; pj: warp density, root/cm; t istj: warp linear density, tex.
The fill cover tightness can be calculated by equation (3):
in the formula (3), Ew: cover tightness,%, in the weft direction; y: the yarn diameter coefficient; pw: weft density, root/cm; t istw: weft linear density, tex.
Wherein, the yarn diameter coefficients of different fibers take the values as follows: 0.0035 terylene, 0.00415 polyamide and 0.00357 cotton.
The following examples and comparative examples respectively use various different fiber materials to prepare the mesh bag of the laundry bag. The preparation method comprises the steps of aligning double-layer fiber materials (the thickness range of each layer is 0.05 mm-0.33 mm), then carrying out overlocking and sewing, then adopting cloth strips with a certain width and the same material to carry out overlock treatment on the overlock positions, manufacturing a washing bag mesh bag after overlock sewing, and then sewing a zipper seal at the mesh bag opening to manufacture the washing bag. During sewing, the shortest stitch length (1mm) of a sewing machine is adopted for sewing, and the manufactured washing bags have the same specification, the length of 50cm and the width of 40 cm. The zipper is a waterproof opening zipper with a full-reflection film.

In addition, the mesh bags of the washing bags of the embodiments 1 to 11 have at least 90% of holes with the aperture less than or equal to 70 μm.
The test methods are illustrated below:
1. pretreatment of test white cloth
The used test white cloth is common fabrics purchased in the fabric market and used for consumer clothes, pretreatment is needed before the test, the test white cloth is put into a common washing bag sold in the market, common detergent is adopted to wash for 3 times in a common drum washing machine, the common impeller washing machine rinses for 3 times, and the white cloth is taken out after rinsing is finished and is naturally dried or dried by a vertical dryer.
2. Washing step
Putting the pretreated test white cloth into a washing bag, putting the test color cloth outside the washing bag, putting the test white cloth into a common roller washing machine together, wherein the weight of the white cloth is 2 times of that of the color cloth, and the washing bags used in the test examples are the same in size (the length is 50cm, and the width is 40 cm); the conditions of the amount of the colored cloth and the amount of the white cloth used in each test example are the same. The test without the laundry bag was also performed under the same conditions. The above washing tests all select default programs, add common detergents, take out after washing, and dry naturally or dry by a vertical dryer.
3. Evaluation method of discoloration prevention effect
Adopting a colorimeter to clean white cloth before washing and clean the white cloth after washingTesting white cloth under the condition of CIE L*a*b*D65 illuminant/10 ° viewing angle, UV 100%, large area of macropore, and calculating the color difference value of the white cloth washed under the condition according to the following formula (4):
in the formula (4), L, a and b are color parameters, wherein L is lightness, a is red-green coordinate, and b is yellow-blue coordinate; l is0、a0、b0: respectively the color parameters of the white cloth before washing; l is1、a1、b1: respectively the color parameters of the washed white cloth.
By calculating the color difference value Delta E of the white cloth without the washing bag0And the color difference value Delta E of the white cloth in the condition bag of the washing bagnJudging whether the laundry bag has the anti-discoloration effect or not. According to "color measurement and computer color matching" (Dong Shao Li et al, China textile Press, 2007), when the color difference value is not more than 0.5, the color difference is hardly recognized by the naked eye, and therefore the discoloration prevention effect is judged by the following method:
1) if Δ E0-△EnIf the color of the laundry bag is less than or equal to 0.50, the laundry bag has no discoloration prevention effect;
2) if Δ E0-△EnIf the color difference is greater than 0.50, the laundry bag has the color change prevention effect, and the larger the difference is, the better the color change prevention effect is.
The laundry bag samples prepared in examples 1 to 11 and comparative examples 1 to 5 were subjected to an anti-tarnishing test under the conditions of two white fabrics, i.e., T-shirt fabric and sweater fabric (the main material is cotton), respectively, and the anti-tarnishing effect was evaluated. The test results are shown in tables 17 and 18, respectively.
Table 17 results of T-shirt testing
Table 18 results of the sweater cloth test
From the test results in tables 17 and 18, it can be seen that the laundry bag mesh bags with the average pore size of less than or equal to 117 μm in examples 1 to 11 have the discoloration prevention effect in different degrees, and can be selected as discoloration prevention laundry bags according to requirements, while the laundry bag mesh bags with the average pore size of more than 117 μm in comparative examples 1 to 5 do not have the discoloration prevention effect.
The washed white cloths in the no wash bag, the example 4 wash bag and the comparative example 2 wash bag were observed after magnification. FIG. 1 is an enlarged view of T-shirt fabric after a washing bag discoloration prevention test, and FIG. 2 is an enlarged view of toilet cloth after a washing bag discoloration prevention test. By observing FIGS. 1-2, the results were found to be as follows: for the test group of the embodiment, the fiber contamination degree is obviously smaller than that of the non-washing bag, and the color difference change of the white cloth in the bag is smaller than that of the non-washing bag, which indicates that the washing bag of the embodiment has a certain anti-discoloration effect. For the test group of the comparative example, the fiber contamination degree of the laundry bag is not obviously different from that of the laundry bag, and meanwhile, the color difference change of the white cloth in the laundry bag is not obviously different from that of the laundry bag, which indicates that the laundry bag of the comparative example does not have the anti-discoloration effect.
From the test results, the laundry bag for preventing discoloration provided by the invention has the discoloration prevention effect, can improve the contamination of shedding fibers and dyes to other clothes during the clothes shuffling, thereby improving the color change condition of clothes with different colors after the clothes are mixed, and can be repeatedly used.
