Description

Technical Field

[0001] The present invention relates to the field of knitted fabrics, in particular to a double-sided functional knitted fabric with a microbubble effect and a weaving process thereof. Background Art

[0002] Knitted fabrics are made by using knitting needles to bend yarn into loops and intertwine them. Knitted fabrics are widely used in clothing fabrics, linings, home textiles and other products, and are currently the mainstream fabric products.

[0003] Existing knitted fabrics mainly change their appearance through dyeing. However, with the development of society, people's pursuit of quality of life is increasing. Simply changing the appearance of fabrics by changing the color of fabrics is no longer able to meet the needs of consumers. It is necessary to increase the three-dimensional sense of fabrics to further improve the beauty of the fabric appearance. However, there is currently a lack of means to increase the three-dimensional sense of fabrics, which makes it difficult to meet the needs of consumers. Therefore, there is still room for improvement. Summary of the Invention

[0004] In order to improve the three-dimensional effect of the fabric, the present application provides a double-sided functional knitted fabric with a microbubble effect and a weaving process thereof.

[0005] In a first aspect, the present application provides a double-sided functional knitted fabric with a microbubble effect, which adopts the following technical solution:

[0006] A double-sided functional knitted fabric with a microbubble effect, comprising a surface fabric and an inner fabric, wherein the surface fabric and the inner fabric are fixedly connected by sewing, wherein the sewing portion between the surface fabric and the inner fabric is in a grid shape, the surface fabric is inelastic, and the inner fabric is elastic;

[0007] The surface fabric is woven from pretreated linen yarn, and the pretreatment method of the pretreated linen yarn is as follows:

[0008] Step 1) adding kelp extract, cumin extract, mulberry bark extract, and corn silk extract into water, mixing until dissolved, adding Shigella sonnei and Bacillus subtilis, and incubating for 3-4 days to obtain a pretreated solution;

[0009] Step 2) The pretreatment liquid is heated to boiling and then the linen yarn is added, and the boiling is maintained for 10-20 minutes. The linen yarn is filtered out and naturally air-dried to obtain the pretreated linen yarn.

[0010] By adopting the above technical solution, the surface fabric is made of inelastic fabric and the inner fabric is made of elastic fabric, and the seams between the surface fabric and the inner fabric are in a grid shape. After the surface fabric and the inner fabric are sewn together, the inner fabric elastically shrinks while the surface fabric does not shrink. As a result, the surface fabric will arch up due to the lack of sewing effect in the internal area of ​​the grid shape at the seam, forming a micro-bubble effect, thereby giving the fabric a better three-dimensional sense, greatly improving the aesthetics of the fabric appearance, and better meeting the needs of consumers.

[0011] However, due to the formation of microbubbles, the surface of the fabric is always uneven, making it easier for dust, bacteria, etc. to deposit on the surface of the fabric. As a result, fabrics with microbubble effects are more likely to breed bacteria than existing flat fabrics, thus threatening people's health.

[0012] Pretreated linen yarn is obtained by pretreating the linen yarn, so that the surface fabric woven from it has excellent antibacterial effect, which can effectively reduce the growth of bacteria and reduce the harm to people's health, making it healthier and of better quality.

[0013] A pretreatment liquid is prepared by specifically selecting kelp extract, cumin extract, mulberry bark extract, and corn silk extract and dissolving them in water. The active ingredients in the kelp extract, cumin extract, mulberry bark extract, and corn silk extract act synergistically with each other to achieve better antibacterial efficacy. By pretreating the linen yarn in a boiling state, the active ingredients can be more firmly adsorbed in the linen yarn, so that the linen yarn can still maintain good antibacterial efficacy for a long time after multiple washings.

[0014] By adding Shigella sonnei and Bacillus subtilis, some irritating substances in kelp extract, cumin extract, mulberry bark extract, and corn silk extract can be removed, thereby reducing the irritation of linen yarn to the skin, and the resulting fabric is more skin-friendly and of better quality. In addition, the combination of Shigella sonnei and Bacillus subtilis can have a certain decolorization effect, reducing the influence of kelp extract, cumin extract, mulberry bark extract, and corn silk extract on the color of linen yarn, and making the color fastness of subsequent dyeing higher and less prone to fading, so that the quality of the resulting fabric is better.

[0015] Preferably, in step 1), 1-3 g of kelp extract, 3-5 g of cumin extract, 2-4 g of mulberry bark extract, and 8-10 g of corn silk extract are added to every 1 kg of water.

[0016] By adopting the above technical solution and specifically selecting the input amounts of kelp extract, cumin extract, mulberry bark extract, and corn silk extract, the linen yarn can have better antibacterial effect and at the same time reduce material waste, thereby having higher economic value.

[0017] Preferably, in step 1), the mass ratio of kelp extract, cumin extract, mulberry bark extract and corn silk extract added into water is 2:4:3:9.

[0018] By adopting the above technical solution and specifically selecting the mass ratio of kelp extract, fennel extract, mulberry bark extract and corn silk extract, the kelp extract, fennel extract, mulberry bark extract and corn silk extract can cooperate with each other better, have a better antibacterial effect, and more effectively reduce the growth of bacteria on the surface of the fabric, thereby threatening human health.

[0019] Preferably, in step 1), 0.1-0.3 g of Shigella sonnei and 1-3 g of Bacillus subtilis are added to every 1 kg of water.

[0020] By adopting the above technical solution and specifically selecting the input amounts of Shigella sonnei and Bacillus subtilis, it is possible to effectively reduce the irritation of pretreated flax yarn and reduce the waste of raw materials, thereby having higher economic value.

[0021] Preferably, the mass ratio of the Shigella sonnei and the Bacillus subtilis added into water is 1:10.

[0022] By adopting the above technical solution and specifically selecting the mass ratio of Shigella sonnei and Bacillus subtilis, the synergistic symbiosis effect of Shigella sonnei and Bacillus subtilis is better, the activity of Shigella sonnei and Bacillus subtilis is higher, and the effect of reducing the irritation of pretreated linen yarn is better.

[0023] Preferably, the inner layer fabric is woven from bamboo-cotton blended yarn.

[0024] By adopting the above technical solution, the inner layer fabric is made from bamboo-cotton blended yarn, so that the inner layer fabric has better elasticity, and after washing, the cotton material has a certain shrinkage effect, which can further increase the shrinkage of the inner layer fabric, thereby making the micro-bubble effect on the surface of the fabric more significant and the three-dimensional sense stronger, making the fabric more beautiful and better meeting the needs of consumers.

[0025] In a second aspect, the present application provides a method for preparing a double-sided functional knitted fabric with a microbubble effect, which adopts the following technical solution:

[0026] A weaving process for the above-mentioned double-sided functional knitted fabric with microbubble effect comprises the following steps:

[0027] Step 1), using pretreated linen yarn to weave a surface fabric through a knitting process;

[0028] Step 2), using bamboo-cotton blended yarn to weave an inner layer fabric through a knitting process;

[0029] Step 3) Cut the surface fabric and the inner fabric into the same shape, with the ratio of the side length of the inner fabric to the side length of the surface fabric being 0.95-0.98:1;

[0030] Step 4) Fixing the surface fabric and the inner fabric with a clamp so that the inner fabric is in a stretched state and the sides of the inner fabric and the surface fabric are completely overlapped;

[0031] Step 5) The inner layer fabric and the surface layer fabric are sewn together by yarn, and the yarn sewing path forms a grid shape, thereby obtaining a double-sided functional knitted fabric with a microbubble effect.

[0032] By adopting the above technical solution and specifically selecting the ratio of the side length of the inner layer fabric to the side length of the surface fabric, the microbubbles formed on the surface fabric after the inner layer fabric shrinks naturally are better, which will not cause serious wrinkles on the surface fabric, and the three-dimensional effect of the fabric is better.

[0033] Preferably, the grid formed by the yarn sewing paths is a square grid, and the side length of the square grid is 10-15 mm.

[0034] By adopting the above technical solution and specifically selecting the side length of the square grid, the microbubbles formed are of more appropriate specifications, less prone to wrinkles, and can reflect a more obvious three-dimensional effect of microbubbles, making the fabric more beautiful and better meeting the needs of consumers.

[0035] In summary, this application has the following beneficial effects:

[0036] 1. Since the surface fabric of the present application is an inelastic fabric and the inner fabric is an elastic fabric, and the seams between the surface fabric and the inner fabric are in a grid shape, after the surface fabric and the inner fabric are sewn together, the inner fabric elastically shrinks while the surface fabric does not shrink. As a result, the inner area of ​​the grid at the seam has no sewing effect, so the surface fabric will arch up, forming a micro-bubble effect, which makes the fabric have a better three-dimensional sense, greatly improves the appearance of the fabric, and can better meet the needs of consumers.

[0037] 2. In the present application, it is preferred to prepare a pretreatment liquid by specifically selecting kelp extract, cumin extract, mulberry bark extract, and corn silk extract and dissolving them in water, and utilizing the synergistic effect of the active ingredients in kelp extract, cumin extract, mulberry bark extract, and corn silk extract to achieve better antibacterial efficacy. By pretreating the linen yarn under boiling conditions, the active ingredients can be more firmly adsorbed in the linen yarn, so that the linen yarn can maintain good antibacterial efficacy for a long time after multiple washings.

[0038] 3. In this application, it is preferred that by adding Shigella sonnei and Bacillus subtilis, some irritating substances in kelp extract, cumin extract, mulberry bark extract, and corn silk extract can be removed, thereby reducing the irritation of linen yarn to the skin, and the resulting fabric is more skin-friendly and of better quality. In addition, the combination of Shigella sonnei and Bacillus subtilis can have a certain decolorization effect, reducing the influence of kelp extract, cumin extract, mulberry bark extract, and corn silk extract on the color of linen yarn, and making the subsequent dyeing color fastness higher and not easy to fade, and the quality of the resulting fabric is better.

[0119] Experiment 1

[0120] According to GB / T20944.1-2007 "Evaluation of antibacterial properties of textiles Part 1: Agar plate diffusion method", the antibacterial properties of the double-sided functional knitted fabrics with microbubble effect prepared in each embodiment and comparative example were tested.

[0121] The double-sided functional knitted fabric with microbubble effect was washed 100 times and then tested for its antibacterial performance again. During washing, the double-sided functional knitted fabric with microbubble effect was placed in a stirring kettle, clean water was injected into the stirring kettle, the speed was 10r / min, and stirring was carried out for 30 minutes.

[0122] Experiment 2

[0123] Chicken embryo test: The irritation score IS of the pretreatment solution prepared in step 1 of the pretreatment method for pretreating linen yarn in each embodiment and comparative example was tested according to SNT 2329-2009 "Chicken embryo chorioallantoic membrane test for eye irritation / corrosion of cosmetics".

[0130]

[0131] According to the data comparison in Table 1, each embodiment has a better antibacterial effect due to the use of a compound of kelp extract, cumin extract, mulberry bark extract, and corn silk extract. The initial antibacterial band width is significantly higher than that of comparative examples 1-4. As the number of washes increases, the width of the antibacterial band gradually decreases. Since the initial antibacterial effect of each embodiment is better, each embodiment has better antibacterial efficacy under the same number of washes, so that the fabrics of each embodiment can maintain the antibacterial effect after more washes, while the comparative examples are more likely to lose the antibacterial effect.

[0132] In addition, since each embodiment uses a combination of Shigella sonnei and Bacillus subtilis, the irritation of the pretreatment liquid is lower, and the resulting fabric is less likely to irritate the skin and is more beneficial to human health. Although the antibacterial effects of the fabrics obtained in Comparative Examples 5 and 6 are similar to those of the embodiments, the irritation of the pretreatment liquid is higher, and the applicability of the resulting fabric for people with sensitive skin is reduced.
