Description
The invention relates to a knitted fabric and application thereof, in particular to a knitted fabric with a temperature and humidity regulating function and application thereof.
With the increasing standard of living in today's society, consumer demands for wearing comfort and functionality of garments are increasing. In addition, people generally increase or decrease clothes according to the cold and hot degree of weather to achieve the aim of temperature and humidity adjustment, but the method is not only troublesome, but also sometimes difficult to achieve, and is particularly prominent in the leisure and sports fields.
For this reason, many studies have been conducted. For example, japanese patent application laid-open No. 2004-316005 discloses a fibrous structure having hygroscopic and exothermic properties, and specifically discloses that the fibrous structure is made of a material having hygroscopic and exothermic properties, and a temperature-sensitive irritant substance is adhered to the surface of the fiber to enhance blood circulation, so that the fibrous structure has more excellent heat-insulating properties and hygroscopic properties, and is mainly used for heat-insulating clothing in winter, but cannot achieve the purpose of temperature adjustment and humidity adjustment for winter and summer.
For another example, chinese patent CN103584385A discloses a garment for cooling and warming, and specifically discloses a garment formed by vertically connecting a cooling layer and a warming layer, wherein the cooling layer is made of ultra-fine imitation silk, the warming layer is made of ultra-smooth imitation wool, and the cooling layer and the warming layer are sewn together by cotton threads, so that the cooling and warming properties are obtained, but the cooling layer and the warming layer are connected by the cotton threads, so that the cotton threads are easy to break after washing for many times, and the durability is required to be further improved.
For another example, chinese patent CN204994641U discloses a moisture-absorbing and heat-generating antistatic sweater, and specifically discloses that the outer layer of the fabric is made of antistatic nylon fiber, the inner layer is made of moisture-absorbing and heat-generating acrylic fiber, the collar part is made of mosquito-repellent regenerated cellulose fiber, and the button is made of magnetotherapy stone, wherein, conductive substances such as carbon black are added into the antistatic nylon fiber, and because the raw materials of the fibers have strong heat absorption, the antistatic sweater is relatively suitable for autumn and winter, and the dual purpose of temperature adjustment, humidity adjustment, winter and summer cannot be realized.
The invention aims to provide a knitted fabric with temperature and humidity regulating function and excellent durability and application thereof.
In order to achieve the above object, the technical solution of the present invention is as follows:
The knitted fabric of the present invention is a double-sided structure including a face a and a face B, wherein a moisture absorption difference Δmr A of the face a and a moisture absorption difference Δmr B of the face B satisfy the following relational expression,
（ΔMR A+ΔMR B）/2≥0.5，
|ΔMR A-ΔMR B|≥0.1。
The knitted fabric has the advantages that the specific moisture absorption rate difference relation exists between the surface A and the surface B, so that the knitted fabric has excellent temperature and humidity regulating effects, can be worn in hot summer and cold winter, has excellent durability, and can be widely used for manufacturing underwear, T-shirts and the like.
Fig. 1 is a weave pattern of an air layer structure according to embodiment 1 of the present invention.
Fig. 2 is a weave pattern change according to embodiment 15 of the present invention.
Fig. 3 is a weave pattern of an air layer according to embodiment 20 of the present invention.
Fig. 4 is a weave pattern of an air layer structure according to embodiment 21 of the present invention.
The ability of fibrous materials to absorb moisture from a gaseous environment is known as hygroscopicity. Moisture absorption is a dynamic process in which the fibers continually absorb moisture and continually release moisture.
The knitted fabric of the invention has a double-sided structure and comprises a surface A and a surface B, wherein the moisture absorption difference delta MR A of the surface A and the moisture absorption difference delta MR B of the surface B meet the following relational expression,
（ΔMR A+ΔMR B）/2≥0.5，
|ΔMR A-ΔMR B|≥0.1
Wherein,
Δmr A = equilibrium moisture absorption at 30 ℃, 90% rh for plane a-equilibrium moisture absorption at 20 ℃, 65% rh,
Δmr B = equilibrium moisture absorption at 30 ℃, 90% rh for plane B-equilibrium moisture absorption at 20 ℃, 65% rh.
The equilibrium moisture absorption rate herein refers to the moisture regain when the moisture absorption and release effects of the fibrous material reach equilibrium stability under specific atmospheric conditions, also referred to as equilibrium moisture regain. The higher the Δmr of the fabric, the lower the water vapor pressure in the garment during medium-strength exercises (e.g., fast walking, dancing), the less the sultry, and the better the comfort.
The knitted fabric of the invention is of a double-sided construction, comprising a face a and a face B. The fabric is of a double-sided structure, and when the fabric is of a double-sided structure, different delta MR can be realized on two sides, and the fabric enters into another temperature and humidity environment from different temperature and humidity environments along with the change of indoor and outdoor temperature difference and air pressure difference, the climate microcirculation in the garment can be changed.
When (DeltaMR A+ΔMR B）/2＜0.5、|ΔMR A-ΔMR B | < 0.1), the hygroscopicity of both sides of the fabric is poor and cannot bring about the effect of temperature and humidity adjustment, therefore, the invention requires (DeltaMR A+ΔMR B)/2 to be more than or equal to 0.5, preferably 1.0 to 8.0, more preferably 1.5 to 7.0, and requires that the absolute value of DeltaMR A-ΔMR B | be more than or equal to 0.1, preferably 0.5 to 9.0, more preferably 1.0 to 5.0.
In hot summer, the outdoor temperature is high and the humidity is high; and the indoor temperature is low and the humidity is low. When a person enters outdoors from indoors, namely from a low-temperature low-humidity environment to a high-temperature high-humidity environment, the sweat yield of the human body is increased, and at the moment, the proper moisture absorption rate difference (delta MR) can enable the fabric to absorb moisture in the air around the skin, so that the stuffiness and discomfort are reduced. In addition, the outside high temperature causes the water to evaporate, a part of vaporization heat is taken away, the temperature and humidity in the microclimate environment between the clothes and the human body can be kept in a lower range, and the human body feels cool.
In cold winter, the outdoor temperature is low, and the humidity is low; and the indoor temperature is high and the humidity is high. When a person enters outdoors from indoors, namely from a comfortable high-temperature high-humidity environment to a low-temperature low-humidity environment, moisture or sweat in the human body is less, fibers with proper moisture absorption rate difference (delta MR) absorb moisture in a microclimate environment, water molecules in motion are absorbed by fiber macromolecules, and the water molecules can convert kinetic energy into heat energy to release heat, so that the microcirculatory environment between clothes and the human body is maintained or regulated, the temperature is kept even higher, and the purposes of heat preservation or temperature rise are realized.
The double-sided structure of the present invention is not particularly limited, and may be a double-sided structure of a single-sided structure, such as a single-sided polyester cotton (or cotton) and cotton) and the like; the multi-layer structure of the single-sided stitch may be a full stitch plating, a partial stitch plating, or the like. Can be a double-layer structure of double-sided tissues, such as double-sided rib, double-sided cotton wool, double-sided variable tissues and the like; the structure can also be a multi-layer structure of double-sided tissue, such as double-sided air layer tissue (sandwich tissue or Wuming tissue), etc. In the case of a double-layer construction of a double-sided weave, the inner yarn is preferably connected in such a way that it does not appear in the surface weave, for example in the form of tuck loops.
The underfill coefficient characterizes the tightness of the fabric, and refers to the ratio between the length of the loops (mm) and the diameter of the yarn (mm). The longer the loop length, the finer the yarn, the greater the underfill coefficient value, and the more space in the facing that is not filled with yarn, the more open the facing. When the ratio a of the underfill coefficients is less than 0.5 or a is more than 2.0, the difference of tightness of the two sides of the fabric is large, namely, the difference of styles of the two sides is large, and the quality of the fabric tends to be reduced, so that the ratio a of the underfill coefficients of the surface A and the surface B in one complete organization and yarn using cycle preferably satisfies the following relation: 2.0 More than or equal to a is more than or equal to 0.5.
In the present invention, the filament number of the yarn forming the surface a and the surface B is not particularly limited, and the filament number of the yarn forming the surface B is preferably 2.2dtex or less. When face B is used as a muscle face (the face closer to the skin), a suitable denier per filament facilitates the face B to absorb more moisture; meanwhile, when the single filament number of the yarn is below 2.2dtex, the yarn is soft in hand feeling, the whole surface B is smoother, a larger contact area is easier to obtain, and heat release and instant conduction are more facilitated for hot summer.
In the present invention, when the fabric is formed of spun yarn and filament multifilament, the exposure rate of the spun yarn on the surface a and the surface B has a large influence on the heat insulation property and the contact cold feeling of the fabric. The staple yarns may be formed from wool, acrylic, cotton, modal, tencel, lyocell, viscose, and the like, and may be formed from far infrared yarns. Far infrared yarns are obtained by adding far infrared particles to the yarns or by means of coatings or the like, such as far infrared polyesters, far infrared acrylons and the like. Preferably, the exposure rate of the spun yarn on the surface A is more than 50%, and the fiber raw material is one or more of wool, acrylic fiber and viscose. Of these, wool is more preferably shrink-proof wool. The shrink-proof wool refers to wool subjected to shrink-proof treatment, namely, scales are removed by chemical, biological and other methods, or scales on the surface of wool fibers are removed by a resin filling and coating method and a combination method of the two methods. When the wool is shrink-proof wool, the gloss and the dimensional stability of the fabric are better. The acrylic fibers can be common acrylic fibers, ultrafine acrylic fibers, and more preferably ultrafine acrylic fibers. The ultra-fine acrylic fiber herein refers to an acrylic fiber having a single filament fineness of 1.1dtex or less. When the acrylic fibers are superfine acrylic fibers, the fabric is softer, has better quality and is more suitable for skin-adhering wearing. In the present invention, the exposure rate of the spun yarn on the surface A is more preferably 70 to 100%. When the exposure rate of the spun yarn on both surfaces exceeds 50%, the surface having a large exposure rate of the spun yarn is used as the surface a and the other surface is used as the surface B in consideration of the temperature and humidity adjustment property.
In the present invention, the total fineness of the yarn on the face a is not particularly limited, and is preferably 30 to 80 denier. When the total fineness of the yarn is lower than 30 inches, the yarn is thicker, the style of the fabric is rough, and the fine sense tends to be reduced; when the total fineness of the yarn is higher than 80 inches, the yarn is thin, the yarn strength is low, and yarn breakage is likely to occur, and in addition, the yarn count is increased, and the cost tends to be increased.
Examples of the fiber raw material of the multifilament yarn on the surface B include polyamide, polyester, viscose, tencel, modal, lyocell, cuprammonium fiber, silk and the like. Preferably, the exposure rate of the filament multifilament yarn on the face B in the present invention is more than 50%, and the fiber raw material thereof is one or more of polyamide, polyester and viscose. The polyester fiber can be common polyester fiber (PET), cationic dye dyeable polyester fiber (CDP), polytrimethylene terephthalate fiber (PTT) and the like. The cross-sectional shape of the fiber raw material is not particularly limited, and may be a circular cross-section, or may be a special cross-section such as a triangle, a cross-shape, or a multi-leaf shape, and the form of the filament is not particularly limited, and may be FDY, DTY, or the like, and preferably FDY. Of these fiber raw materials, fibers having a high thermal conductivity such as polyamide fibers are more preferable. When the exposure rate of the filament multifilament on the surface B is more than 50%, a good cool touch can be imparted to the surface B. In the present invention, the exposure rate of the filament multifilament yarn on the surface B is more preferably 70 to 100%. When the exposure rate of the filament multifilament on both surfaces exceeds 50%, the surface having a large exposure rate of the filament multifilament is used as the surface B and the other surface is used as the surface a in view of temperature and humidity adjustment.
In the present invention, the total fineness of the yarn on the surface B is not particularly limited, and is preferably 33 to 165dtex, more preferably 55 to 84dtex. When the total fineness of the yarn exceeds 165dtex, the yarn is thicker, the fabric style is rough and thick, evaporation of water is possibly affected, and the temperature and humidity regulating effect tends to be reduced; when the total fineness of the yarn is lower than 33dtex, the yarn is thinner, the strength is lower, the phenomenon of yarn breakage possibly occurs during weaving, and meanwhile, the thinner the yarn is, the thinner the fabric is, and the temperature and humidity regulating effect tends to be reduced.
The temperature and humidity regulating effect of the invention refers to the capability of generating a temperature difference value with the surrounding environment after a fabric enters one fixed temperature and humidity condition from another temperature and humidity condition. The simulation conditions during the specific test are as follows: when the environment changes from indoor to outdoor in winter, the indoor temperature and humidity are 20 ℃ multiplied by 65%RH, and the outdoor temperature and humidity are 10 ℃ multiplied by 30%RH; when the environment changes from indoor to outdoor in summer, the indoor temperature and humidity are 20 ℃ multiplied by 65%RH, and the outdoor temperature and humidity are 30 ℃ multiplied by 90%RH.
In the present invention, it is more preferable that the ratio of exposure of the spun yarn on the surface a is more than 50%, the ratio of exposure of the filament multifilament is less than 50%, and the ratio of exposure of the spun yarn on the surface B is less than 50%, so that the difference in performance between the surfaces can be ensured to the maximum extent, that is, the surface a has excellent heat insulating property, the surface B has excellent contact cold feeling, and the difference is remarkable.
In the present invention, the clo value of the surface A is preferably 0.65 or more, and the qmax value of the surface B is preferably 0.12 or more.
In the process of manufacturing the fabric of the present invention, water absorbing agent, softening agent, antistatic agent, etc. may be selected for processing at the time of finishing as needed. The water absorbing agent may be a polyester resin, an acrylic resin, or the like. The softening agent may be silicone resin or the like. The antistatic agent may be cationic, anionic, nonionic, compound, etc., such as alkyl sulfonate type anionic antistatic agent, quaternary ammonium salt type cationic antistatic agent, etc.
The clothing made of the knitted fabric is not limited in wearing scene, can be worn on one side all the year round, and can be worn on two sides alternately according to seasonal changes.
