Description

Technical Field

[0001] The invention relates to a double-sided wearing fabric and a manufacturing method thereof, and belongs to the field of textiles. Background Art

[0002] With the development of social economy and the improvement of people's living standards, people's pursuit of clothing is not limited to the design of styles, but more attention is paid to the comfort and functionality of clothing. For example, some clothing suitable for wearing in high temperatures is woven with yarns that have a cool feeling. The fabric provides a cool feeling when in contact with the skin, but it will feel damp under the action of sweat and easily breed bacteria, so it needs moisture absorption, quick drying and antibacterial functions; for clothing suitable for wearing in low temperatures, simply thickening will be bloated, which does not conform to the aesthetic views of modern people. For this reason, heat-storing and warm-keeping yarns are used for weaving, or the fabric is processed to form a certain amount of fluff to achieve warmth.

[0003] In the southern region, the temperature difference between day and night is large in spring and autumn, and functional fabrics that simply provide cooling or simply store heat are difficult to meet the demand. For example, if you wear clothing made of cool yarn at 30 degrees Celsius during the day, the temperature drops sharply after sunset, and it is not appropriate to continue to provide a cool feeling. Summary of the invention

[0004] In order to overcome the shortcomings of the prior art, the present invention provides a double-sided wearing fabric and a manufacturing method thereof, wherein one side provides a cool feeling when worn at a high temperature, and the other side maintains heat when worn at a low temperature.

[0005] The technical solution adopted by the present invention to solve its technical problem is:

[0006] In a first aspect, the present application provides a method for making a double-sided wearing fabric, which is applicable to a double-sided circular knitting machine, comprising the following steps:

[0007] Weaving: In the longitudinal weaving direction, the fabric is woven by a plurality of first tissues, each of which includes a first face yarn and two second face yarns looped by the lower needle cylinder, and a cool bottom yarn looped by the upper needle disc; the cool bottom yarn loops once every other needle, the cool bottom yarns in adjacent first tissues are not looped in the same row, and the cool bottom yarn is looped once every even-numbered needles by the lower needle cylinder; in the same first tissue, the weaving behaviors of the two second face yarns are completely consistent, and the first face yarn does not loop in the row where the second face yarn loops, and the second face yarn does not loop in the row where the first face yarn loops;

[0008] Coating: applying a heat-insulating coating to the side of the woven cloth showing the first yarn and the second yarn.

[0009] In the manufacturing method of the double-sided wearing fabric provided by the present application, the first veil and the second veil form the front side of the process, and the cool base yarn forms the back side of the process. The cool base yarn is looped once every other stitch, and the cool base yarns in adjacent first tissues are not looped in the same column. In addition, the looping positions of the first veil and the second veil are complementary, so that every four yarns form a row in the actual product, that is, each first tissue forms a row in the actual product, thereby providing a whole cool base yarn on the back side of the process to contact the human body, and the cool base yarn is looped once every even-numbered stitches, which does not conflict with its looping mode, and the looping is used to connect the front side of the process and the back side of the process; the two second veils in each first tissue are looped at the same time, and a bulge will be formed relative to the position where a single first yarn is looped, and the front side of the fabric process is covered with a heat-insulating coating. When the front side of the process is used to contact the skin, the side walls of the bulge and the flat part of the front side of the process form a basin-shaped space. After the top opening of the basin-shaped space is covered by the skin, the air in the basin-shaped space is difficult to flow, thereby achieving a warming effect.

[0010] Furthermore, the second veil is made of pure cotton yarn with a count of 15S-60S.

[0011] The thickness of the coating is 0.1μm-50μm, and the touch provided by this thickness is negligible. When the temperature is low and the garment is worn with the reverse side facing outward, the protrusions formed by the second veil are equivalent to direct contact with the skin. The pure cotton fiber has good skin-friendliness, feels comfortable, and has good moisture absorption, making it more comfortable when worn with the reverse side facing outward.

[0012] Furthermore, between the weaving and coating steps, there are singeing and impurity removal steps, and the impurity removal requirements are as follows: the desizing enzyme concentration is 6g / L-10g / L, the penetrant is 1g / L-2g / L, the treatment temperature is 60°C-70°C, and the treatment time is 2min-5min.

[0013] The hairiness and impurities on the surface of pure cotton fibers increase the surface area of ​​the yarn, which consumes more coating during coating, and part of the coating cannot be truly bonded to the yarn, reducing the effect of the coating. Pre-singing and using desizing enzymes to remove impurities before coating can remove most of the hairiness and impurities on the surface of the cloth, which is conducive to a better bonding effect between the coating and the yarn.

[0014] Furthermore, the singeing requirement is that only one side of the first veil and the second veil is presented by the singeing blank obtained by the knitting, the singeing temperature is 300° C.-500° C., and the machine speed is 75 m / min-85 m / min.

[0015] The cool base yarn can be made of one or more of Coolmax, jade fiber and mica fiber. These fibers can provide a cool touch feeling, but have poor fire resistance. The melting deformation after high temperature will affect the effect of these functional fibers. The singeing temperature is used in conjunction with the vehicle speed, and only the front side of the process is burned. The hairiness of the pure cotton fiber is burned as much as possible while ensuring that the function of the cool base yarn itself is not deteriorated.

[0016] Furthermore, between the impurity removal and coating steps, there is a wax removal step: the cloth blank after impurity removal is placed in a wax removal solution containing 4g / L-8g / ethanol and 1g / L-2g / L penetrant, and wax removal is performed with 800 Hz-1200 Hz ultrasonic wave.

[0017] There are some waxes in pure cotton fibers that are difficult to remove by desizing alone. Removing these waxes can improve the water absorption of pure cotton fibers on the one hand, and facilitate the close bonding of the cloth blank and the coating on the other hand. In the prior art, high-temperature scouring is generally used to remove waxes, and the processing temperature is generally 90°C-95°C, which consumes a lot of energy. In the present application, ethanol can dissolve waxes under the action of ultrasound, and the penetrant accelerates the dissolution of waxes, so that the waxes in pure cotton fibers can be removed in a low-energy manner.

[0018] Furthermore, between the dewaxing and coating steps, there is an oxidation step: the dewaxed cloth is placed in an oxidizing solution containing 2g / L-4g / L sodium hypochlorite and 1g / L-2g / L sodium hydroxide, and ozone is introduced into the oxidizing solution for 5min-8min.

[0019] Chlorine bleaching can destroy the structure of cotton fibers and make them soft. Ozone can further destroy the structure of cotton fibers and improve the wetting effect of cotton fibers, which is conducive to close bonding with the coating. However, excessive chlorine bleaching can damage the fabric, so the sodium hypochlorite concentration and treatment time need to be strictly controlled.

[0020] Furthermore, the cool base yarn is tucked once every six stitches, and the tucks in the six adjacent first stitches are not in the same row.

[0021] The denser the tucks, the stronger the bonding between the front and back sides of the process, but the fabric will be harder. In the present application, tucks are performed every six stitches, and the six adjacent tucks in the first tissue are not in the same row, which ensures that the front and back sides of the process can be well bonded, avoids the appearance of convex strips on the back side of the process, and makes the back side of the process smooth.

[0022] Furthermore, the coating comprises 10 wt%-35wt% of hollow glass microspheres, 2 wt%-10wt% of fumed silica, 10 wt%-15wt% of a binder, and the balance is polyester resin.

[0023] Furthermore, the second veil is looped according to a preset pattern, and the preset pattern includes a "cross" pattern and a "mouth" shaped pattern, the height of the "cross" pattern and the "mouth" shaped pattern is three to five of the first tissues, the width of the "cross" pattern and the "mouth" shaped pattern is three to five columns, the "cross" pattern and the "mouth" shaped pattern are not connected, the minimum height between the "cross" pattern and the "mouth" shaped pattern is less than three of the first tissues, and the minimum width difference between the "cross" pattern and the "mouth" shaped pattern is less than three columns.

[0024] When the temperature is low, the raised side walls and the flat front part of the craft form a basin-shaped space to trap air and achieve heat preservation. The smaller the size of a single basin-shaped space, the more difficult it is for the air to flow in it. At the same time, the easier it is for the skin to cover the top of the basin-shaped space, and the better the heat preservation effect. The setting method of the above preset pattern is conducive to making the basin-shaped space more densely distributed, which is conducive to improving the heat preservation effect.

[0025] In a second aspect, the present application provides a double-sided wearing fabric, which is made by the method described in the first aspect. Each four-way weaving process forms a row in the actual fabric, the back side of the process has a large flat cool base yarn in contact with the skin, and the front side of the process has a protrusion covered with a heat-insulating coating on the surface, which can retain air and achieve heat preservation after close contact with the skin. When the temperature is high, the back side of the process is worn inward, and when the temperature is low, the front side of the process is worn inward, which is conducive to obtaining a more comfortable effect at different temperatures.

[0026] The beneficial effects of the present invention are as follows: the fabric produced by the present invention provides a whole surface of cool bottom yarn on the back side of the process for contact with the human body, and a bulge is formed on the front side of the process by relying on the second yarn. The side wall of the bulge and the flat part of the front side of the process constitute a basin-shaped space. After the top opening of the basin-shaped space is covered by the skin, the air in the basin-shaped space is difficult to flow, thereby achieving a warming effect. When the temperature is high, the back of the process is worn inwards, and when the temperature is low, the front side of the process is worn inwards, which is conducive to obtaining a more comfortable effect at different temperatures. When the weather temperature difference changes greatly, the front and back sides can be reversed to adapt to changes in the external environment.

[0027] Other features and advantages of the present application will be described in the following description, and partly become apparent from the description, or understood by practicing the present application. The purpose and other advantages of the present application can be realized and obtained by the structures particularly pointed out in the written description and the drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Figure 1 It is a weaving design pattern provided in an embodiment of the present application.

[0029] Figure 2 is with Figure 1 The corresponding preset pattern. DETAILED DESCRIPTION

[0030] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0031] The disclosure below provides many different embodiments or examples to implement different structures of the present invention. In order to simplify the disclosure of the present invention, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present invention. In addition, the present invention can repeat reference numbers and / or reference letters in different examples, and this repetition is for the purpose of simplification and clarity, which itself does not indicate the relationship between the various embodiments and / or settings discussed.

[0032] It is generally believed that the normal temperature range of the human body in a static state is only 36-37℃. High or low temperature is not good for human health and affects the psychological state and labor productivity. Clothes are part of the process of regulating and controlling body temperature, but existing fabrics are difficult to provide coolness when the temperature is high and keep warm when the temperature is low. Some solutions use hollow porous fabrics to store air, but the ventilation capacity is too strong and the insulation effect is poor.

[0033] The present application provides a method for manufacturing a double-sided wearing fabric, which is applicable to a double-sided circular knitting machine, and includes the following steps:

[0034] Weaving: In the longitudinal weaving direction, the fabric is woven from multiple first tissues, each of which includes a first veil, two second veils and a cool base yarn. The cool base yarn is looped once every other needle, and the cool base yarns in adjacent first tissues are not looped in the same row. The cool base yarn is tucked once every even number of needles; in the same first tissue, the weaving behavior of the two second veils is completely consistent, and the first veil in the row where the second veil is looped does not loop, and the second veil in the row where the first veil is looped does not loop. Among them, the first veil and the second veil are looped using the lower needle cylinder of the double-sided circular knitting machine; the cool base yarn is looped using the upper needle disk of the double-sided circular knitting machine and tucked using the lower needle cylinder.

[0035] Coating: Apply a heat-insulating coating to the side of the woven cloth showing the first yarn and the second yarn.

[0036] In the manufacturing method of the double-sided wearing fabric provided by the present application, the first veil and the second veil form the front side of the process, the cool base yarn forms the back side of the process, the cool base yarn is looped once every other stitch, and the cool base yarns in adjacent first tissues are not looped in the same column, and the looping positions of the first veil and the second veil are complementary, so that every four yarns form a row in the actual product, that is, each first tissue forms a row in the actual product, thereby providing a whole surface of the cool base yarn on the back side of the process to contact the human body, the cool base yarn is looped once every even-numbered stitches, which does not conflict with its looping mode, and the loops are used to connect the front side of the process and the back side of the process; each first tissue The two second veils in the middle form a loop at the same time, and a bulge is formed relative to the position where the single first veil forms a loop. The front side of the fabric is covered with a heat-insulating coating. When the front side of the fabric is in contact with the skin, the side walls of the bulge and the flat part of the front side of the fabric form a basin-shaped space. After the top opening of the basin-shaped space is covered by the skin, the air in the basin-shaped space is difficult to flow, thereby achieving a warming effect. When the front side of the fabric faces outward, the basin-shaped space is not covered by the skin, and when the temperature is high, a coat will not be worn, and the basin-shaped space cannot be closed. The air can directly pass over the front side of the fabric. Therefore, when the front side of the fabric faces outward, the effect of trapped air and heat preservation will not be achieved.

[0037] The cool bottom yarn can be selected from one or more of Coolmax, jade fiber and mica fiber. Coolmax can achieve rapid moisture conduction by using its structure, and transport the water vapor generated by the human body outward for evaporation, thereby achieving a cool feeling. Both jade fiber and mica fiber are obtained by mixing the powder of the corresponding stone into the fiber, which produces a contact cool feeling when in contact with the skin. The weaving method in the embodiment of the present application can obtain a whole surface of cool fiber on the reverse side of the process, which can contact the skin over a large area. The second veil is made of pure cotton yarn with a count of 15S-60S. The thickness of the coating is 0.1μm-50μm, and the touch provided by this thickness is negligible. In the method of wearing the reverse side of the process outward at a lower temperature, the bulge formed by the second veil is equivalent to direct contact with the skin. The pure cotton fiber has good skin-friendliness, comfortable hand feel, and good hygroscopicity, making it more comfortable when wearing the reverse side of the process outward.

[0038] The hairiness and impurities on the surface of pure cotton fibers increase the surface area of ​​the yarn, which consumes more coating during coating, and part of the coating cannot be truly bonded to the yarn, reducing the effect of the coating. In some embodiments, the steps become: weaving-singeing-removing impurities-coating, wherein the requirements for removing impurities are that the concentration of desizing enzyme is 6g / L-10g / L, the penetrant is 1g / L-2g / L, the treatment temperature is 60℃-70℃, and the treatment time is 2min-5min. Singeing is performed in advance before coating and impurities are removed by using desizing enzyme, which can remove most of the hairiness and impurities on the surface of the cloth, which is conducive to a better effect of combining the coating with the yarn.

[0039] Since the cool base yarn is made of Coolmax, jade fiber, mica fiber and other fibers with polymer as the base material, the fire resistance is poor, and the melting deformation after high temperature will affect the effect of these functional fibers. Furthermore, the requirement for singeing is that only one side of the woven cloth showing the first veil and the second veil is burned, the singeing temperature is 300℃-500℃, and the speed is 75 m / min-85m / min. Use this singeing temperature with the speed, and only burn the front side of the process, and burn the hairiness of the pure cotton fiber as much as possible while ensuring that the function of the cool base yarn itself is not deteriorated.

[0040] The coating comprises 10 wt%-35wt% of hollow glass microspheres, 2 wt%-10wt% of fumed silica, 10wt%-15wt% of a binder, and the balance is polyester resin, which is a slurry-type polyester resin for textiles. The coating is prepared by mixing the raw materials according to the above mass ratio, stirring at a speed of 1000 rpm-1300 rpm for 30-40 minutes.

[0041] There are still some waxes in the pure cotton fiber that are difficult to remove by desizing operation alone. Removing these waxes can improve the water absorption of the pure cotton fiber on the one hand, and on the other hand, it is conducive to the close combination of the cloth blank and the polyester-based coating. In some embodiments, the steps become: weaving-singeing-removing impurities-removing wax-coating, and the cloth blank after impurities removal is placed in a wax removal solution containing 4g / L-8g / ethanol and 1g / L-2g / L penetrant, and dewaxed with 800 Hz-1200Hz ultrasound. In the prior art, high-temperature scouring is generally used to remove wax, and the treatment temperature is generally 90℃-95℃, which consumes a lot of energy. In the present application, ethanol can dissolve wax under the action of ultrasound, and the penetrant accelerates the dissolution of wax, so that the wax in the pure cotton fiber can be removed in a low-energy way.

[0042] Furthermore, the steps become: weaving-singeing-removing impurities-removing wax-oxidation-coating, the dewaxed cloth is placed in an oxidation solution containing 2g / L-4g / L sodium hypochlorite and 1g / L-2g / L sodium hydroxide, ozone is introduced into the oxidation solution, and the treatment is carried out for 5min-8min. Chlorine bleaching can destroy the structure of cotton fibers and make them soft. Ozone can further destroy the structure of cotton fibers, improve the wetting effect of cotton fibers, and facilitate close bonding with the coating. However, excessive chlorine bleaching can damage the fabric, so it is necessary to strictly control the concentration of sodium hypochlorite and the treatment time.

[0043] In some embodiments, the steps are changed to: weaving - singeing - impurity removal - wax removal - oxidation - shaping - coating. The fabric is shaped in a shaping machine with a speed of 20 m / min -30 m / min and a treatment temperature of 150°C -180°C, which can effectively improve the shape retention of the fabric and prevent the knitted fabric from becoming loose after long-term use.

In fact, the 13th route is connected to the top of the 12th route) and Figure 2 The embodiments shown, Figure 2 A preset pattern representing the minimum repetitive weave of a fabric.

[0051] The 1st, 2nd and 3rd needles of the 7th and 8th needle cylinders form a circle, while the other needles do not form a circle, and the upper needle disc does not form a circle;

[0052] The 1st, 3rd, 4th, 5th and 6th needles of the 9th needle cylinder form a circle, while the other needles do not form a circle, and the upper needle plate does not form a circle;

[0053] The 4th needle of the 10th needle cylinder is tucked, and the other needles are not looped. All the high heel needles of the upper needle plate are looped, that is, the 1st, 3rd, and 5th needles are looped;

[0054] The second needle of the lower needle cylinder of the 11th and 12th routes forms a circle, while the other needles do not form a circle, and the upper needle disc does not form a circle;

[0055] The 13th needle cylinder has the 1st, 2nd and 3rd needles in a circle, but the rest of the needles do not form a circle, and the upper needle plate does not form a circle;

[0056] In the 14th route, the 5th needle of the lower needle cylinder is tucked, and the other needles are not looped. All the low heel needles of the upper needle plate are looped, that is, the 2nd, 4th, and 6th needles are looped;

[0057] The 4th and 6th needles of the lower needle cylinder of the 15th and 16th routes form a circle, while the rest of the needles do not form a circle, and the upper needle disc does not form a circle;

[0058] The 17th needle cylinder has the 1st, 2nd, 3rd and 5th needles in a circle, but the rest of the needles do not form a circle, and the upper needle plate does not form a circle;

[0059] The 6th needle of the 18th needle cylinder is tucked, and the other needles are not looped. All the high heel needles of the upper needle plate are looped, that is, the 1st, 3rd, and 5th needles are looped;

[0060] The 4th, 5th and 6th needles of the lower needle cylinder of the 19th and 20th needles form a circle, while the rest of the needles do not form a circle, and the upper needle disc does not form a circle;

[0061] The 1st, 2nd and 3rd needles of the 21st needle cylinder form a circle, while the other needles do not form a circle, and the upper needle plate does not form a circle;

[0062] In the 22nd route, the first needle of the lower needle cylinder is tucked, and the other needles are not looped. All the low heel needles of the upper needle plate are looped, that is, the 2nd, 4th, and 6th needles are looped;

[0063] The 4th, 5th and 6th needles of the lower needle cylinder in the 23rd and 24th routes form a circle, while the rest of the needles do not form a circle, and the upper needle disc does not form a circle either.

[0064] Thus, the first veil and the second veil are presented on the front side of the process, such as Figure 2 At a in the middle, a cool bottom yarn is shown on the reverse side of the process (due to the shrinkage of the knitted fabric, the cool bottom yarn blocks the first veil and the second veil. The first veil and the second veil can still be seen by stretching the fabric). Figure 2 The first veil forms the flat part of the front side of the craft, the second veil forms the convex part of the front side of the craft, and the back side of the craft has a whole cool bottom veil in contact with the skin.

[0065] The denser the tucks, the stronger the bonding between the front and back surfaces, but the harder the fabric will be. In this embodiment, the cool base yarn is tucked every six stitches, and the tucks in the adjacent six first tissues are not in the same row. This ensures that the front and back surfaces can be well bonded, and avoids the appearance of convex strips on the back surface, making the back surface smooth and the fabric softer.

[0066] And if Figure 2As shown, the preset pattern in this embodiment includes a "cross" pattern and a "mouth" pattern, the height of the "cross" pattern and the "mouth" pattern (the number of rows in the actual fabric) is three first tissues, the width of the "cross" pattern and the "mouth" pattern is three columns, the "cross" pattern and the "mouth" pattern are not connected, the minimum height between the "cross" pattern and the "mouth" pattern is less than three first tissues, and the minimum width difference between the "cross" pattern and the "mouth" pattern is less than three columns. The setting method of the preset pattern is conducive to making the basin-shaped space more densely distributed, which is conducive to improving the thermal insulation effect.

[0067] Experimental group Figure 1 The fabric was woven with the weaving design of the experimental group, in which the cool yarn was CoolMax, the first veil was 32S pure cotton yarn, and the second veil was 32S pure cotton yarn; the thickness of the thermal insulation coating obtained by coating the front side of the process was about 10μm, and the weight of the fabric was measured to be 452g / ㎡; the fabric was cut and sewn into a bag (the diameter of the bag when opened was about 15cm), with the front side facing inward. The control group wove the fabric with ordinary double rib weave, in which all yarns were 16S pure cotton, and coated with a thermal insulation coating of the same thickness as the experimental group, and the weight of the fabric was measured to be 453.6g / ㎡; the fabric was cut and sewn into bags of the same specifications as the experimental group, with the side with the thermal insulation coating facing inward. Take three balloons #1, #2, and #3, and fill each with 2 liters of 48°C water. Insert a thermometer into the mouth of the balloon and seal it tightly. Put the #1 balloon into the bag of the experimental group, put the #2 balloon into the bag of the comparison group, and leave the #3 balloon unwrapped. The three balloons filled with 48°C water are placed in a room at 26°C. The indoor wind speed is 0.3m / s-0.6m / s. Measure the time required for the thermometer in each balloon to drop from 48°C to 28°C. In the end, the #1 balloon took 51 minutes, the #2 balloon took 44 minutes, and the #3 balloon took 27 minutes. This shows that the fabric of the embodiment of the present application has a better warming effect when the gram weight is equivalent to that of ordinary fabrics.
