Description

TECHNICAL FIELD

[0001] The invention relates to the technical field of knitted dress fabric, and more particularly to a moisture-absorbing heat-generating quick-drying moisture-retaining thermal fabric and manufacturing method thereof.

BACKGROUND OF THE INVENTION

[0002] In recent years, the development trend of knitting industrial in our county focuses on an - application of new material fiber, a promotion of new spinning technology, an application of energy saving and environmental protection dyeing technology and an integration of industrial technology and information technology, etc.. As for the development trends, there are great development and progress from hardware to software for each knitting enterprise, such as new technology, new process, new device, new environmental protection dyeing accessories, new controlling means and the application of new quality standard.

[0003] With the gradually improvement on life standards, a high requirement on the comprehensive thermal-moisture conformability of knitted garment is put forward. Since a standard "moisture-absorbing thermal knitted underwear" issued by Ministry of Industry and Information Technology in December, 2010, most of knitted fabrics whose moisture-absorbing heat value meet the standard is knitted by blended yarn which mainly consisted of the moisture-absorbing thermal fiber EKS raw material produced by Japan Toyobo co., ltd. As most of the blended fibers are polyacrylonitrile raw materials, the pilling property is poor and the appearance of the garment fabric will be affected by long-time dressing. It is extremely urgent to develop a new moisture-absorbing thermal fabric with the existing natural raw material, regenerated cellulose fibers and mature new chemical fibers to break technical barriers of the Japan's raw material. At present, the knitted dress fabric mainly adopts the cellulose fibers, the protein fiber, the regenerated cellulose fiber and a mixture thereof, such as cotton, modal, rayon, wool cashmere, mulberry silk and linen. It has a function of natural moisture-absorbing, antibacterial, warm-keeping and skin protection. With the help of the introduction of spandex elastomeric yarns, the knitted dress has a better body fitting and a function of free stretching. However, these fabrics have the following defects. The wet permeability and moisture liberation are poor. After a long-time wearing, sweat will adsorbed on the fabrics and a lot of sweat can not be output timely. When the body motion is reduced or static, the sweat stick to the body will make the person feel clammy and the conformability is poor. Furthermore, evaporation rate and the amount of water vapor permeability are two characteristic indexes for the quick-drying performance of the fabric. They represent the evaporation rate and the amount of water vapor permeability of the whole fabric. The differences between the quick-drying performance of the inner layer of the fabric and that of the outer layer of the fabric can not be represented. In fact, a lot of moisture-absorbing quick-drying products have been developed by the developer for the knitted fabrics. The sweat permeates from the inner layer of the fabric to the outer layer of the fabric rapidly. As the sweat transfers from the inner layer to the outer layer rapidly with such method, the skin is dry and comfortable. However, since the development of these fabrics is limited by the development of sports knitted fabrics, the idea is rarely applied to the development of the knitted underwear fabric. In addition, in order to meet the requirement that the heat preservation rate of the thermal knitted fabric underwear is no less than 30%, most of the thermal knitted underwear is made by a weaving process which adopts air layer silk. Thus, the elasticity of the fabric is poor and the pilling of polyester fiber low stretch yarn will come out, so that the appearance and the performance of the underwear will be greatly affected. Except for the poor elasticity and the pilling, the moisture/gas permeability is very poor, and thus a strong muggy feeling and a clammy feeling will arise when dressing.

[0016] The moisture-absorbing thermal, moisture-absorbing quick-drying, moisture and thermal principles of the fabric are as follows.

[0017] The moisture-absorbing and heat-generating principle is as follows. The components of the moisture-absorbing heat-generating fabric have a better hydrophily or a strong wicking and moisture transferring function. The materials of this invention mainly are the regenerated cellulose fiber enriched with a lot of hydrophilic groups and the cotton fiber, so that the fabric has a better moisture absorption performance. When the specific surface area and the specific surface energy of the modified polyester fiber yarn having a non-circular cross section, such as the cross-type cross section, the Y-type cross section or the ∞-type cross section, are larger than that of a common polyester fiber yarn having a circular cross section, it has a strong wicking and wet permeability function, so that the water absorption rate of the fabric meets the requirements of the national standards or exceeds it. However, if only the water absorption rate of the fabric meets the requirements, the fabric can not be called as the moisture-absorbing and thermal fabric. When weaving, the first yarn whose main component is the regenerated cellulose fiber is placed on the outer layer of the fabric and the third yarn whose main component is the cotton fiber is placed on the inner layer of the fabric, so that water molecules in the fabric will transfer from inside to outside due to the different hygroscopicities after the moisture absorption. The water molecules continuously transfer and acutely move in the fabric, and thus the integral heat and the differential heat will be produced and the kinetic energy will convert to heat energy, thereby generating heat. Finally, the fabric must have an enough height to prevent from the heat loss or have much hollowness and still air. In this invention, the outer layer of the fabric is formed by the first yarn and the fourth yarn via a full-needle single knitting method. The outer layer fabric is compact, so that it can effectively prevent from the heat loss. The main components of the inner layer of the fabric are formed by the single knitting in which half of stitches of the third yarn are used at regular intervals without the polyurethane fiber yarn of the fourth yarn, so that the fabric is sparse. In addition, a lot of micro gaps are caused by the raising and pilling in the following process and more still air exists in the fabric, so that the heat converted by the moisture-absorbing water molecular motion is not easy to be lost and the highest heating value and the average heating value of the moisture-absorbing can meet the requirements of the national standard.

[0018] The moisture-absorbing and quick-drying principle is as follows. The characteristics of the moisture-absorbing defined by the national standard are shown in the following three indexes, namely the water absorption rate, the dripping water diffusion time and the wicking height. The characteristics of the quick-drying are shown in the following two indexes, namely the evaporation rate and the mositure permeability. However, the above five indexes have a certain limitation on the quick-absorbing and quick-drying characteristic, so that they can only represent the moisture-absorbing and quick-drying performance of the whole fabric rather than the differences in the moisture-absorbing and quick-drying performance of the inner and outer layer of the fabric. The conventional moisture regains of the inner layer of the fabric is different from that of the outer layer of the fabric. The material of the inner layer is also hydrophilic and the weighted average conventional moisture regains is relatively low. The material of the outer layer is hydrophilic and the weighted average conventional moisture regains is far higher than that of the material of the inner layer. The quick-drying of the inner layer not only passes through the natural evaporation quick-drying channel of the surface layer, but also passes through the strong moisture absorption channel of the material of the outer layer, and thus the moisture absorbed by the inner layer is transferred to the outer layer quickly and diffuses rapidly via a middle wicking and moisture transferring layer, so that the quick-drying performance of the inner layer is superior to that of the outer layer.

[0019] Moisturizing principle is as follows. The middle layer of the fabric is weaved by the second yarn which is the modified polyester fiber yarn having a non-circular cross section and the fourth yarn which is polyurethane fiber yarn. As the modified polyester fiber yarn having the non-circular section has a larger specific surface area, it has a stronger wicking and moisture transferring function. The wicking and moisture transferring function is bidirectional, which not only can exhaust the moisture from the inner layer of the fabric to the outer layer thereof, but also can exhaust the moisture from the outer layer of the fabric to the inner layer thereof. The weighted average conventional moisture regains of the material of the outer layer of the fabric is large and the material contains a lot of hydrophilic groups, so that it has a strong function of capturing the water molecules in the air. When a certain amount of water molecules exist in the air, the outer layer of the fabric will adsorb a lot of water molecules and the water molecules can further be transferred to the inner layer via the middle layer of the fabric so as to keep a balance of the moisture absorption and get the goal of moisture-retaining and anti-aging. When perspiring, the sweat will transfer to the outer layer of the fabric rapidly. Due to the hydrophilic groups in the outer layer of the fabric, the evaporation rate of the moisture is relatively low and the sufficient moisture in the outer layer creates a condition for the moisturization of the inner layer. When the skin becomes dry, the outer layer will capture the moisture from the air or from non-evaporation and non-volatilization moisture before the moisture absorption and moisture storage, and the bidirectional moisture transferring function of the middle layer of the fabric will help to transfer the moisture to the inner layer of the fabric to keep a balance of the moisture absorption, thereby retaining moisture.

[0020] Thermal principle is as follows. The hollow design of the fabric is not obvious to the improvement on the warmth retention of the fabric having the polyurethane fiber. However, the fleece design of the inner layer of the fabric very notably improves the warmth retention. After the fleece, a lot of micro gaps will are brought in the inner layer of the fabric, a lot of still airs exist in the fabric and the polyurethane fiber yarn of the outer layer of the fabric is introduced, the outer layer is relatively compact, so that it can effectively prevent the air from flowing between the human body and the outer layer of the fabric, thereby greatly improving the warmth retention of the fabric via the possessing capacity of the still airs. In this invention, a lot of micro gaps are brought in the fabric after the fleece of the inner layer and a lot of still airs exist in the micro gaps. Moreover, the first yarn and the fourth yarn are weaved by a method of full-needle knitting. As the polyurethane fiber yarn of the fourth yarn has a good elasticity and shrinkage performance, the outer layer of the fabric is relatively compact due to the introduction of the full-needle and the fourth yarn and it can prevent the loss of the energy, the fabric can keep warm. In order to obtain the function of this invention, the design of the knitting process diagram is based on the following principles. Firstly, the moisture-absorbing and quick-drying performance of each component is made full use to the greatest extent, especially the performance of the moisture discharging from the inner layer to the outer layer. The polyurethane fiber yarn is not added to the third yarn of this invention. The single knitting in which half of the purl stitches or the knit stitches are used at regular intervals to make the structure of the fabric sparser after the fleece and facilitate the moisture-permeating and quick-drying of the inner layer. The outer layer of the fabric adopts the knitting in which all the knit stitches or the purl stitches of the first yarn and the fourth yarn are used, so that the fabric is compact, which facilitates the quick outside transferring and gathering of the moisture gas in the inner layer. Secondly, under the condition that without affecting the hydrophilic performance of each component, the ratio of each component are changed to optimize the textile process, reduce the weighted average moisture regain of the inner layer of the fabric to the greatest extent, increase the weighted average moisture regain of each component in the outer layer of the fabric. In this invention, half of the knit stitches and or the purl stitches of the second yarn and the fourth yarn are used at regular intervals to form the looping knitting. Half of the corresponding purl stitches or knit stitches are used at regular intervals to form the tucking knitting. The above knitting joins the design of the inner layer and the middle layer of the fabric rather than the design of the outer layer of the fabric, so that it can effectively reduce the weighted average official moisture regain of each component of the outer layer and is convenient to the moisture permeating, the moisture transporting and quick drying since the official moisture regain of the modified polyester fiber low stretch yarn is low. Thirdly, it must facilitate the fleece and napping of the inner layer and ensure that the root portion of the fleece will not fall off. This invention adjusts the design by each yarn feeding way and applies the coil index theory in the field of textile engineering, so that the napping and the loop forming coil of the third yarn becomes longer and longer and protrudes on the surface of the fabric, thereby facilitating the fleece and the napping and locking the napping. The second yarn and the fourth yarn loop forming coil of the third yarn coil root which joins the inner layer becomes smaller and caves in to avoid the linting. The third yarn can be fixed in the single knitting in which half of the needles are used and the single knitting in which half of two kinds of knitting needles are used at regular intervals. In each way, the first yarn and the fourth yarn form the single knitting in which all the needles are used and the third yarn forms the single knitting in which half of the needles are used. They correspond to the looping knitting in which half stitches of the second yarn and the fourth yarn are used at regular intervals and the tucking knitting of the double knitting in which the inner layer and the outer layer are connected. In the inner layer and the outer layer, half of the knitting needles of other disk are used at regular intervals to form the tucking knitting. The knitting needles of the double knitting which participates in the looping kintting are same with the knitting needle of the half needle single knitting of the third yarn, so that the coil formed by the looping knitting of the double knitting locks the root of the coil formed by the third yarn firmly, thereby creating a condition for the fleece of the subsequent process. Fourthly, the fabric is comfortable and has elasticity. To make the fabric has a comfortable elasticity, the design for the structure of the fabric must meets the following requirements. The polyurethane fiber yarn is not introduced into the yarn-feeding way of the third yarn except for the fleece and the napping. The polyurethane fiber yarn is introduced or guided to other yarn feeding way. The polyurethane fiber yarn has a good tensile performance and restorability. The polyurethane fiber yarn is not introduced in the yarn feeding way of the third yarn which has been conduct with the napping and the fleece to facilitate the napping in the subsequent process, so that it can ensure that the fabric has enough elasticity and the fleece and the napping of the inner layer will not be affected.

[0021] At the same time, in the preparation method, after the dyeing liquor containing the disperse dye and the auxiliary agent are used to dye the modified polyester fiber, the reductive cleaning process is conducted after the middle and dark color are dyed. The main object is removing the dye floating color adhere to the modified polyester fiber after the high-temperature sublimation and the floating color of other disperse dye adhere to other materials, so that it can improve the colorfastness of the whole fabric. After the reductive cleaning, the thermal washing and the cool washing are conducted to prepare for the dyeing of the regenerated cellulose fibre, the cotton fiber and other fibers. The reactive dye or other dye and the auxiliary agent are adopted to dye the regenerated cellulose fiber, the cotton fiber and other fiber according to the components of the fabric blanks which have not been dyed and the dye process curve. After the dyeing, the cool washing and the acid washing are conducted. The cool water is added slowly to the vat to reduce the temperature. At the same time, the water is released. After the releasing of the water, the acid washing is conducted under the normal temperature according to the water level required by the liquor ratio. The object is mainly neutralizing the residual alkali on the cloth. After the acid washing, the soaping agent is used to soap to remove all the dye floating color to the greatest extent until the dye floating color are cleaned. Then, the cool water is added slowly. After the water is released completely, a cylinder of water is added for cool washing. After the cool washing, a cylinder of water is added according to the required liquor ratio. The hydrophilic softener and the hydrophilic soft olein are added to the cleaned fabric semi-finished products by soaping and cool washing the floating color. The cleaned fabric semi-finished products are kept in the vat. The hydrophilic softener and the hydrophilic soft olein are added to the vat. The fabric semi-finished products are soaked circularly under the normal temperature. Before adding the hydrophilic softener and the hydrophilic soft olein, the weak acid is used to acid wash the fabric semi-finished products for 10~20min. As the hydrophilic softener and the hydrophilic soft olein will have a better effect under the weak acidity, the PH value of the dye liquor is adjusted to 4.5~6 and the dye liquor exhibits the weak acidity. The adding of the hydrophilic softener aims at the hydrophilic soft finishing of the modified polyester yarn having a non-circular section or the polyester staple fiber. The adding of the hydrophilic soft olein aims at the hydrophilic soft finishing of the cotton fiber in the third yarn and the first yarn or the linen, the wool or the cashmere and the regenerated cellulose fiber. The surface of the cloth being treated with the hydrophilic soften has a soft feel, a good hydrophilic effect and the fluffy cotton fiber to facilitate the napping and the fleece of the subsequent process. A tensile shrinkage drying machine is used to dry the fabric semi-finished products which have been conducted with hydrophilic treatment. The raising machine is used to nap the dried fabric semi-finished product. After the napping, the fabric has a uniform delicate touch. The napping process directly relates to the quality of the fabric and the achievement of the heat preservation rate of the fabric. Finally, the repeated setting is conduct to the fabric semi-finished product which has been napped. The temperature of the repeated setting is no more than 160° C to avoid forming the floating color caused by the sublimation and dissociation of the disperse dye molecules on the polyester fiber which will reduce the dye colorfastness of the fabric.
