Description
Technical Field
The invention belongs to the technical field of textile dyeing and finishing processes, and particularly relates to a temperature-control knitted underwear fabric and a manufacturing method thereof.
Background
The temperature control fabric is a novel fabric capable of reacting to environmental conditions, can effectively control the temperature of the fabric by absorbing or releasing heat, has a bidirectional temperature regulation effect, and provides a comfortable microclimate environment for a human body. In the current fabric market at home and abroad, the knitted high-grade temperature control fabric is very few, mainly adopts temperature control fiber as a raw material, is high in price and is almost not available at home. The knitted high-grade temperature control fabric is specially designed for clothing fabrics contacting with skin, and is mainly applied to close-fitting fabric clothing such as high-grade underwear, sportswear, vests and the like. The high-grade knitted temperature control fabric has the advantages of good thermal comfort, controllable dryness and cooling potential, thermal buffering performance, no toxicity, no harmful substances and the like. Therefore, the method has design and development performance and can fill the blank of domestic markets. In the market, the knitted underwear fabric is mainly made of cotton products, mainly because the cotton fibers have good hygroscopicity, under normal conditions, the pure cotton fibers can absorb moisture in the surrounding atmosphere, and the moisture content of the pure cotton fibers is 8-10%, so that people feel soft but not stiff when the pure cotton fibers contact the skin of people. The cotton fiber is poor conductor of heat and electricity, the heat conduction coefficient is extremely low, and because the cotton fiber has porosity, a large amount of air can be accumulated between the fibers, and the air is poor conductor of heat and electricity, the pure cotton fiber textile has good warmth retention property and wearing comfort. Because of good hygroscopicity and heat retention and moderate price, the cotton fiber is favored by consumers.
However, cotton fibers are poor in quick-drying property and slow in moisture release, and if the ambient humidity is high, the cotton fibers can easily absorb a large amount of moisture in air, so that people feel very moist and cool after wearing the cotton fabric for a long time. In summer with high temperature, the light and thin pure cotton fabric is easy to gather with sweat generated on the surface of skin, is not easy to volatilize, has a sticky body feeling and is poor in heat insulation. Nowadays, with the improvement of living standard and the enhancement of health consciousness and environmental consciousness of people, the requirements of people on underwear and clothes are continuously improved. The existing underwear has the characteristic of single comfort and can not meet the requirements of people. Besides the comfort of the underwear fabric, the functionality, the environmental protection and the health of the underwear fabric are more and more favored by people.
Therefore, in view of the disadvantages of cotton fibers, it is necessary to develop a controllable knitted underwear fabric that reacts to environmental conditions, and a relative dynamic thermal balance is established between human body and external environment, so as to achieve an active temperature regulation effect on human body, reduce the influence of external environment temperature on human body, prevent people from feeling cold or hot suddenly due to sudden changes in external weather, protect the health of people, and reduce the occurrence of common diseases.

Compared with the prior art, the invention has the following beneficial effects:
firstly, the method comprises the following steps: the invention adopts combed cotton 40S yarn and 20D spandex to weave full-lining stretch fabric as grey cloth, and then the temperature control knitted underwear fabric is prepared through the steps of preliminary setting → pretreatment → dyeing → soaping → drying → setting and the like, wherein the temperature control auxiliary agent AC-03 and silicone oil T718 are added in the setting process to process the fabric, so that the temperature control auxiliary agent forms a polymer film on the surface of the fabric yarn, and after moisture is contacted with the yarn, the moisture is diffused quickly and is evenly distributed to the surface of each fiber, and further, the moisture evaporation or cooling is promoted if necessary. When the external environment temperature rises, the temperature control film layer on the surface of the fiber can promote the water to be quickly evaporated, the water is converted into gas from liquid, and the heat is absorbed, so that the change of the external environment temperature to the environment temperature between the fabric and a human body is reduced. When the temperature of the external environment is reduced, the temperature control film layer on the surface of the fiber promotes the water to be converted from liquid to solid, the phase conversion process releases heat, a relative dynamic heat balance is established between a human body and the external environment, and the temperature regulation effect on the human body is achieved. The influence of the external environment temperature on the human body is reduced, so that the human body can not suddenly change in temperature or suddenly change in temperature due to the external weather, the human body can be protected, and the generation of common diseases is reduced;
secondly, the method comprises the following steps: the dyeing process is improved on the basis of the prior art, the dyeing process of the fabric is determined according to the relation between the dyeing temperature, the dyeing time, the heating rate and the K/S value, when the dyeing process adopts the heating rate of 1 ℃/min and is carried out for 40min at the temperature of 60 ℃, the uniformity of cloth cover dyeing can be ensured to the maximum extent, the dyeing process time is shortened, and the quality problems of dyeing defects, uneven coloring and the like are avoided;
thirdly, the method comprises the following steps: the internal qualities of the temperature control knitted underwear fabric meet the domestic textile detection requirements, and the temperature control effect of the temperature control knitted underwear fabric is obviously better than that of the temperature control materials of the same type by the detection of the temperature control technology of HeiQ company of Switzerland (namely the test on the temperature regulation performance in the specific implementation mode of the invention). In addition, the temperature control materials of the same type of temperature control fabrics in the existing market are high in price and poor in temperature control effect, are formed by blending multiple fibers, are not beneficial to dyeing and finishing post-processing, and are high in production risk and high in cost;
fourthly: the combed cotton 40S cotton yarn adopted by the invention has good hygroscopicity and softness, the 20D spandex is added, so that the fabric has elasticity and stretchability, and after the temperature control auxiliary agent is added for finishing, the defect of slow moisture release of the cotton fiber is overcome, the moisture absorption and quick drying performance of the cotton fiber is improved, and the wearing comfort and the temperature regulation function of the fabric are obviously improved. A relative dynamic balance is established between the human body and the external environment, and the positive temperature control and regulation effects are achieved on the human body. Therefore, the temperature-control knitted underwear fabric can be widely applied to next-to-skin underwear fabrics and sports garment fabrics, and has good application prospect and high cost performance;
fifth, the method comprises the following steps: the internal stress of the grey cloth can be eliminated through preliminary setting (presetting), the fabric width and the gram weight can reach the specified standards of customers, the fabric surface is smooth, the hand feeling is soft, and the defects of dyeing color splash, dead cross and the like are reduced. The technological requirements of selecting 20D spandex yarn for blank setting are strict, and the setting temperature, time (vehicle speed) and other technological parameters have great influence on the fabric surface effects of fabric such as width, gram weight, elasticity after dyeing, hand feeling, crease and the like. Therefore, the invention strictly sets the initial setting process, determines the initial setting parameter temperature of 198 ℃, the vehicle speed of 26m/min and the upper and lower overfeeding of 45%/6%, and lays a good foundation for the fabric quality; meanwhile, the pretreatment is the first process of the textile in dyeing and finishing processing. The pretreatment aims to remove natural impurities on the fiber and oil stains attached in the spinning and weaving process. The invention adopts the refining degreasing agent SF-2, caustic soda flakes, hydrogen peroxide, neutralization acid 6004 and deoxyenzyme DM-8618, and the cotton yarns are subjected to high-temperature oxygen bleaching in a Basoni low bath ratio dyeing machine, so that the cotton yarns have smooth surfaces, high whiteness, good capillary effect, soft hand feeling and better permeability, the excellent quality of the fibers is fully exerted, and qualified semi-finished products are provided for dyeing.

TABLE 1 application formula of temperature control auxiliary agent pad dyeing
TABLE 2 temperature control adjuvant dip-dyeing application formula
In order to achieve the best performance of the temperature control assistant, the following matters are taken:

Secondly, before adding the temperature control auxiliary agent, the unfixed dye and the residual chemical substances on the fabric are thoroughly removed through reduction cleaning or soaping.
③ citric acid or acetic acid is used for adjusting the pH value to make it weak acidic (pH value is 4.5-6).
In the pad dyeing application formula, the actual dosage of the temperature control auxiliary agent is 3 percent per mangle liquor ratio is optimal.
When the ordinary fabric and the fabric of the temperature-controlled knitted underwear obtained in example 3 of the present invention are respectively contacted with moisture, the dynamic schematic diagrams of the fabric fibers contacting with moisture are shown in fig. 6 and 7, and can be known from the moisture dynamic schematic diagrams of fig. 6 and 7: after the yarns of the common fabric are contacted with water, the yarns are partially wetted and have low flowing speed; according to the fabric yarn subjected to temperature control treatment, the temperature control auxiliary agent forms a polymer film on the surface of the yarn, and when moisture is contacted with the yarn, the moisture is diffused quickly and is evenly distributed to the surface of each fiber, so that the moisture is promoted to evaporate (cool) if necessary.
Example 4
The cotton fibers were dyed according to the dyeing method described in step three of example 3, and the resulting cotton fibers were tested.
Example 5
This example differs from example 4 in that the dyeing temperature was 40 ℃ and the cotton fiber obtained was tested.
Example 6
This example differs from example 4 in that the dyeing temperature was 50 ℃ and the cotton fiber obtained was tested.
Example 7
This example differs from example 4 in that the dyeing temperature was 70 ℃ and the cotton fiber obtained was tested.
Example 8
This example differs from example 4 in that the dyeing temperature was 80 ℃ and the cotton fiber obtained was tested.
The cotton fibers obtained in examples 4 to 8 were subjected to leveling property and K/S test to obtain the effects of different dyeing temperatures on the color depth and leveling property of the cotton fibers, and the test methods are as follows:
K/S value test: accurately weighing 0.2g of dyed cotton fiber, smoothing with a brush, measuring the K/S value at the maximum absorption wavelength by using a Datacolor SF 600X color measurement formula instrument with an ultra-micro aperture, performing color calculation by using a CIE standard illuminant D65 and a 10-degree visual angle standard observer, measuring at different positions for 3 times, and taking an average value.
Leveling property: evaluation was by visual inspection under standard lighting box simulated daylight conditions.
The test results are shown in table 3 and fig. 4, respectively.
TABLE 3 Effect of dyeing temperature on leveling Properties of cotton fibers
| Dyeing temperature/. |
40 | 50 | 60 | 70 | 80 |
| Levelling property | In general | In general | Is preferably used | Is preferably used | Is preferably used |
As can be seen from FIG. 4 and Table 3, the K/S values of the dyed cotton fibers showed a tendency to increase and decrease with increasing dyeing temperature. When the dyeing temperature is lower, the motion capability of the dye is lower, the dye is not easy to permeate into the fiber during dyeing and is gathered on the surface of the cotton fiber, and the dye is easy to wash and fall off in the later soaping process, so that the K/S value after dyeing is lower, when the dyeing temperature is increased to 60 ℃, the motion capability of the dye is enhanced, the K/S value of the cotton fiber after soaping is high, and the level-dyeing property is better. If the temperature is continuously increased, the K/S value and the level-dyeing property of the cotton fiber are not improved, but the color light of the dyed cotton fiber is changed. In general, the dyeing temperature is preferably 60 ℃.
Example 9
This example differs from example 4 in that the dyeing time was 20min and the cotton fibers obtained were tested.
Example 10
This example differs from example 4 in that the dyeing time was 30min and the cotton fibers obtained were tested.
Example 11
This example differs from example 4 in that the dyeing time was 50min and the cotton fibers obtained were tested.
Example 12
This example differs from example 4 in that the dyeing time was 60min and the cotton fibers obtained were tested.
The cotton fibers obtained in examples 4, 9 to 12 were subjected to leveling property and K/S test, and the effects of different dyeing times on the color depth and leveling property exhibited by the cotton fibers were obtained, and the results are shown in fig. 5 and table 4.
TABLE 4 Effect of dyeing time on levelness of dyed cotton/viscose/hemp fibers
| Dyeing time/ |
20 | 30 | 40 | 50 | 60 |
| Levelling property | Difference (D) | In general | Is preferably used | Is preferably used | Is preferably used |
As can be seen from FIG. 5 and Table 4, the change in the K/S value of the dyed cotton fiber did not tend much as the dyeing time increased, and tended to be stable after 40 min. But has a great influence on the level-dyeing property of dyed cotton fibers. In the initial dyeing stage, the dye is rapidly adsorbed on the surface of the dyed cotton fiber and rapidly diffused on the surface of the cotton fiber to form accumulation, so that the color yield of the cotton fiber is high at the beginning, and the K/S value is high. With the increase of dyeing time, the dyes accumulated on the surface of the cotton fiber start to hydrolyze, and redundant dyes are diffused and permeated to the cotton fiber with less dyes, so that the leveling property of the cotton fiber is improved. Therefore, when the dyeing time is 40min, the K/S value and the level-dyeing property of the cotton fiber are good. In general, the dyeing time is preferably 40 min.
Example 13
This example is different from example 4 in that the temperature rising rate at the time of dyeing was 0.5 ℃/min, and the obtained cotton fiber was subjected to a test.
Example 14
This example is different from example 4 in that the temperature rising rate at the time of dyeing was 1.5 ℃/min, and the resulting cotton fiber was subjected to a test.
Example 15
This example is different from example 4 in that the temperature rising rate at the time of dyeing was 2 ℃/min, and the obtained cotton fiber was subjected to a test.
The cotton fibers obtained in examples 4, 13 to 15 were subjected to leveling property test, and the effects of different dyeing temperature-raising rates on the leveling property of the cotton fibers were obtained, and the results are shown in Table 5.
TABLE 5 Effect of temperature Rate of heating on leveling Properties of Cotton fiber fabrics
| Heating rate/min | 0.5 | 1 | 1.5 | 2 |
| Levelling property | Good taste | Good taste | In general | Difference (D) |
As can be seen from Table 5, when the dyeing temperature is 60 ℃ and the temperature is kept for 40min, and the temperature rise rate is controlled to be 0.5-1 ℃/min, the level dyeing effect of the cotton fiber is good, and the temperature rise rate is controlled to be 1 ℃/min on the premise of improving the production efficiency and ensuring the product quality.
The basic performance of the temperature control knitted underwear fabric obtained in the embodiment 3 is detected, and the fabric obtained is subjected to various evaluations such as intrinsic quality index of knitted finished fabric and the like by adopting an enterprise standard of Q/FZFZ015-2013 novel temperature control fabric knitwear and combining national standards of GB 18401 national safety technical Specification for textile products and GB/T22848 knitted finished fabric and the like. The results are shown in Table 6.
Table 6 basic performance test results of the temperature-controlled knitted underwear fabric obtained in example 3 of the present invention
As can be seen from the table above, all physical indexes of the temperature control knitted underwear fabric prepared by the invention all meet the standard requirements of Q/FZFZ015-2013 Enterprise Standard of novel temperature control fabric knitwear, GB 18401 basic safety technical Specification of national textile products, GB/T22848 knitted finished cloth and the like.
The dynamic evaporation rate performance of the temperature control knitted underwear fabric obtained in the example 3 is tested, the temperature regulation performance does not have a unified test method and standard at present, the test is usually carried out by a thermal analysis method, a temperature change method, a heat preservation instrument method, a microclimate instrument method and the like, and the temperature regulation performance of the temperature control fabric is discussed by the dynamic evaporation rate.
The dynamic moisture test results are shown in table 7 below:
table 7 dynamic moisture test results
Dynamic moisture control environment reference is made to table 8 below:
TABLE 8 dynamic moisture test Environment reference method
As can be seen from tables 7 and 8, the evaporation rate of the temperature-controlled knitted underwear fabric prepared by the invention after washing is far higher than that in a reference environment, and the temperature regulation and control capability is strong. Namely, the higher the evaporation rate, the slower the temperature change of the fabric, and the stronger the temperature control and regulation capacity. The temperature control auxiliary agent is a water functional polymer, and can absorb or release heat on the surface of the fiber to effectively control the temperature of the fabric. When the external environment temperature rises, the fiber surface temperature control film layer promotes the moisture to evaporate rapidly, the moisture is converted into gas from liquid, and the heat is absorbed, thereby reducing the change of the external environment temperature to the environment temperature between the fabric and the human body. When the temperature of the external environment is reduced, the temperature control film layer on the surface of the fiber promotes the water to be converted from liquid to solid, and the phase conversion process can release heat, so that a relative dynamic heat balance is established between a human body and the external environment, and a positive temperature regulation effect is achieved on the human body.
The drip diffusion time test and the fabric capillary test were performed on the temperature-controlled knitted underwear fabric obtained in example 3, and the results are shown in tables 9 and 10 below, respectively:
TABLE 9 drip diffusion time test results
