The present invention relates to a water-absorbent quick-drying knitted fabric and application thereof, in particular to a water-absorbent quick-drying single-sided knitted fabric and application thereof.
In recent years, with the continuous improvement of living standards, the functional demands for sportswear worn with body contact, or for T-shirts and POLO shirts worn in spring and summer, and so on are also becoming increasingly higher and higher. This is because it is prone for people to sweat a lot, when they sport or when the outdoor temperature is relatively high in spring and summer. If the sweat cannot be timely absorbed, evaporated, or diffused by the fabric, the swollen fiber due to the moisture absorption may block the void positions of the fabric. It makes the skin in an anaerobic environment, and thus makes people feel very sultry and reduces the comfort feeling.
At present, there are a lot of water-absorbent quick-drying fabrics on the market. Most of them are double sided circular knitted fabrics. For example, Chinese patent application CN201210296683.0 discloses a double sided knitted fabric. Its surface layer is the fine denier polyester yarn, and its inner layer is the multi-leaf profile polyester yarn partially or wholly. By the multi-leaf profile polyester yarn of the inner layer, the reverse side provides water-absorbent effect, and then, the moisture absorbed by the inner layer is transferred to the surface through the fine denier polyester yarn in the surface layer. Thus the purpose of the sweat absorption and perspiration is achieved. But such fabric has a relatively flat inner layer so that the fabric is easy to adhere to the skin and to affect the dry and comfortable feeling of the skin after absorbing sweat. In addition, after the sweat absorption, the inner layer yarns cannot timely diffuse all of water content to the surface, resulting in swelling phenomena so that the holes of the fabric are blocked. Thus, it makes the skin in an anaerobic environment, and thus makes people feel very sultry, and reduces the comfort feeling.
For another example, China patent application CN201180049196.8 discloses a multilayer structure knitted grey fabric, wherein a certain amount of cellulose-type long fibers are provided near the inner surface (skin side) of the grey fabric. It solves the problem of sultry feeling due to insensible perspiration or a small amount of sweat, and the sticky, wet, cool feeling and other problems due to the profuse sweating caused by sports, etc. However, in fact, even if the skin contact surfaces are of the concave-convex structure, because the cellulose-type long fibers with excellent water-absorbent and moisture absorption performance are used, a part of the water will still remain in the skin contact surface, so that the wet feeling and other problems still cannot be completely solved. In addition, since a double jersey has smaller fiber gap compared with the single jersey, the time needed for water to be transferred to the surface is relatively longer, and the quick-drying property is poorer.
For another example, Japanese Laid Open Patent Application H10-131000 discloses a kind of water-absorbing and quick-drying knitted fabric, wherein a certain concave-convex height difference is provided on the reverse side of this fabric. By using fine denier viscose filament or viscose/polyester combined filament yarn in the concave part and using polyester filament in the convex part and the surface, the problems such as sultry feeling and skin touch feeling are solved. However, since non-elastic polyester filaments are used for the convex part of the reverse side, the yarn shrinkage is poor, so that the concave-convex height difference is not enough even in case that concave-convex structure is formed on the reverse side. In the case of a lot of sweat, the moisture is still difficult to be immediately diffused to the surface, which adversely affect the quick-drying property.
For another example, Japanese Laid Open Patent Application H2011-226026 discloses a kind of knitted fabric for clothing material, wherein two kinds of yarns are used in its reverse side, i.e., hydrophobic synthetic fiber with the water repellency for the convex part, and the hydrophobic synthetic fiber without the water repellency for other parts. Although such yarn combination, adopted on the reverse side of the fabric, improves the sticky feeling more or less in case of sweating a lot, the water-absorbent property of the reverse side is greatly reduced because the water repellency yarn is used in the convex part. Moreover, the function of moisture diffusion to the surface also declines accordingly, so that the overall quick-drying of the clothing material deteriorates, and that the sultry feeling when wearing is still existing.
Therefore, the quick drying property of water-absorbent quick-drying fabric in the prior art needs further improvement and perfection.
The purpose of the present invention is to provide a single-sided knitted fabric with excellent water-absorbent quick-drying property, which is suitable for making T-shirts or POLO shirts, etc.
In order to achieve the above purposes, the present invention consists of the following:
The present invention is obtained by combining unique yarn structures with specific structures. The obtained fabric is light and thin, has excellent water-absorbing and quick-drying properties, enhanced wearing comfort, and it is suitable for use in manufacturing T-shirts, polo shirts, and the like.

Considering the lightness of wearing; single sided structure is applied for the water-absorbent quick-drying fabric of the present invention. Compared with the double sided knitted fabric formed by yarns with the same fineness, the single sided structure has lower gram weight, and is more favourable for sports. Moreover, to obtain more excellent water-absorbent quick-drying effect than double sided knitted fabric, a concave-convex structure is provided on the reverse side of the single-sided knitted fabric in the present invention. The fabric contacts with human body only in part (point contact), and the gap between fibers is large, which consequently increases the circulation space for evaporation of the sweat liquid (water vapor). Even though there is a large amount of sweat, the water content can be diffused to the fabric surface rapidly and timely, and the dry and clear feeling inside the clothes can be kept.
A concave convex structure with proper convex height can effectively prevent sweat (water vapor) from remaining on the reverse side of the fabric and thus, the convex height in the length direction of the reverse side of the fabric in the present invention is 40˜150 μm, preferably 40˜100 μm. If the convex height is less than 40 μm, after human body sweats a lot, the reverse side of the fabric is too smooth and prone to adhere to the skin, resulting in the discomfort. Meanwhile, the sweat (water vapor) absorbed by such side is difficult to be timely led to the surface. The water retaining amount is increased, and the yarns become swelling, and the original knitted holes in the fabric become smaller. It causes skin in the anaerobic environment during continuous sports, resulting in sultry feeling. The fabric in the present invention is of the single sided structure. Consequently, the higher the convex height is, the larger the gaps between fibers become. so that sweat will be quickly transferred to the fiber surface during continuous sport activity, and the dry and clear feeling of the skin-contacting surface is always maintained. On the other hand, the convex height cannot be too large. When it exceeds 150 μm, the convex parts may irritate skin during wearing, resulting in rough and the itch feeling, which is adverse to sports.
In the present invention, the fiber forming the convex parts of the reverse side of the fabric is very critical from two major points discussed below. Firstly, if non-polyester fibers such as cellulose fiber or nylon fiber are used, a large amount of water content can be absorbed on the reverse side of the fabric, because these fibers have relatively superior hygroscopicity. In such case, a part of the water content is difficult to be diffused to the surface timely, which results in the increase of the water retaining amount in the reverse side, causing the decrease of wearing comfort and the sultry feeling. On the other hand, if the non-elastic polyester fibers are used, the shrinkage degree of the yarn in the processing process after knitting is too small to form a convex with a height of 40˜150 μm and the quick-drying effect is not significant. Therefore, as the fiber at convex parts of the reverse side in the fabric of the present invention, polyester elastic fibers are used.
In addition, the distance between adjacent convex parts in the concave-convex structure is also very important. It largely affects the water absorption and rapid transmissibility in the reverse side of the fabric. Therefore, in the length direction of the reverse side of the fabric in the present invention, the distance between adjacent convex parts is preferably 50˜400 μm, more preferably 100˜300 μm. In case of the above ranges, the water-absorbent—rapid transmission—dry and clear effects of the fabric can become best. If the distance between adjacent convex parts is less than 50 μm, the moisture transmission from the reverse side to the surface might be prevented. It increases the wet feeling of the reverse side, and reduces the wearing comfort. If the distance between adjacent convex parts is more than 400 μm, although the moisture is easily diffused to the fabric surface, the probability of the convex parts in the reverse side contacting the skin will decrease simultaneously, so that the skin may directly contact with the fabric surface. Because the moisture and sweat are concentrated on the surface, people will feel sticky and sultry. Especially when sweating a lot during the sport activities, the sticky feeling, wet feeling, and cold feeling will become more serious.
The polyester elastic fiber used in the present invention is preferably the elastic fiber with a contract recovery rate (CR value) of 30˜70%. The polyester elastic fiber with a CR value within the range, has good crimp contraction property, and the fabric formed by such fiber has convex with appropriate height in the reverse side. Even sweating a lot, no sultry feeling occurs, and the dry and clear feeling when contacting with the skin is more superior. The CR value is more preferably 40˜60%.
There is no special restriction for the polyester elastic fiber types used in the present invention. It can be the single-component elastic fiber, the two-component juxtaposed elastic fiber, or the high elastic false twist processing yarn, and the like. It is preferably PBT, PTT, PBT/PET, PTT/PET, high viscosity PET/low viscosity PET. There is no special restriction for its form. It can be fully drawn yarn (FDY) or false twist yarn DTY.
The fineness of polyester elastic fiber used in the present invention is preferably 30˜150 danier (D), more preferably 40˜100D, so as to guarantee the gram weight and the soft hand feeling of the fabric.
The fabric in the present invention is of the single sided structure. The yarns cross knitted with polyester elastic fiber appear on the fabric surface and the concave parts of the reverse side. Although there is no special restriction on the fiber types of the cross knitted yarns, if only cotton, viscose, nylon, and other high moisture-absorbing fibers are used, it may be difficult to guarantee that the sweat (water vapor) can be led to the surface maximally and timely, and consequently guarantee the maintenance of the superior dry and clear feeling of the skin-contacting surface. Therefore, the cross knitted yarns preferably at least include ordinary PET (non-modified PET) fiber. Its cross section can be round or profiled. In case of profiled cross section, it can be cross, triangle, star, cross/round, and so on. In addition to the above ordinary PET fiber, the cross knitted yarns can also contain spandex (PU), cotton, viscose, nylon, etc, for not only ensuring the superior water-absorbent quick-drying property, but also imparting more functions to the fabric.
The cross knitted yarns in the present invention preferably are 100% ordinary PET (non-modified PET) fibers. Namely, the fabric in the present invention is preferably made of 100% polyester fiber. This can ensure that the fabric has a superior ratio of outer/inner water retention rate.
When the above yarns cross knitted with the polyester elastic fiber are short fibers, the yarn fineness thereof is not particularly limited. The commercially available yarns can be used. However, when short fiber is used, due to the hairiness of staple yarn surface formed by short fiber, water vapor may be absorbed, and the diffusion of moisture on the surface may be hindered. Long fiber is preferred since the diffusion of moisture will not be hindered due to smooth surfaces possessed by long fiber. In order to guarantee the soft hand feeling, excellent water-absorbent quick-drying property, and snaging property, the monofilament fineness of the long fiber used is preferably 0.3˜2.5D, more preferably 0.4˜2.0D.
The structure used in the present invention is preferably changing pique, changing pique stripes, changing pique stripes with interlaced thickness, etc. The changing pique structure is produced by the composite of the looping, tucking, and floating wire. Convex parts with suitable height are obtained based on the traditional pique structure in combination with suitable tuck stitch. The changing pique stripes and the stripes with interlaced thickness can be obtained on the basis of the changing pique in combination with different kinds of yarns (i.e., yarns different in raw materials, gloss, or cross section). However, the structure is not limited to the above, any single sided structure which can form the concave-convex structure in the reverse side of a knitted grey fabric can be used.
The production method of the water-absorbent quick-drying knitted fabric in the present invention is as below. In the 24 G˜36 G single-sided round knitting machine, at least polyester elastic fiber and other fibers are subjected to cross knitting, to provide the knitted grey fabric. Afterwards, the obtained knitted grey fabric is subjected to pretreatment, dyeing, and post-treatment processing, resulting in a product wherein its reverse side has a concave-convex structure, the height of the convex parts of the concave-convex structure is 40-150 μm, and the fiber forming the convex parts is a polyester elastic fiber. For the conditions for the pretreatment, dyeing, and post-treatment processing, conventional conditions are applied. The pretreatment and dyeing can be performed in the same bath or separately. In addition, suitable chemicals can be added to each process as required. For example, refining agents, bleaching agents, and so on can be added during pretreatment. Hydrophilic agents, anti-static agents, neutralization acids, and so on can be added in the post-treatment processing. Preferably, hydrophilic agents are added in the dyeing or post-treatment processing, so as to achieve more excellent water-absorbent quick-drying property. The refining agents, hydrophilic agents, and so on used in the present invention can be the commercially available products. The amount of each chemical is preferably 0.1˜20 g/L.
The gram weight of the knitted fabric in the present invention is preferably 50˜250 g/m2, depending on different seasons and different usage. More preferably, it is 100˜200 g/m2. The light design is especially suitable for sportswear.
For the knitted fabric in the present invention, the water retention rate of its reverse side (inside) is preferably 10% or less, more preferably 5% or less. Its ratio of outer/inner water retention rate is preferably 5.0 or more, and more preferably 5.0-30.0. Its water-absorbent property is preferably 5 seconds or less, and more preferably 2 seconds or less. The greater the ratio of outer/inner water retention rate (ratio value) is, the smaller the inner water retention rate is, and the better the quick drying property of the fabric is. Even in the case of profuse sweating, sweat can also be absorbed rapidly and transferred timely to the surface. The skin-contacting surface is always kept dry and clear, and the comfort and the sport effects of continuous wearing will not be affected.
The knitted fabric of the present invention can be used to produce T-shirt, POLO shirts, and the like for the sport or everyday wearing. It has no special restriction on style. Either long-sleeve style or short-sleeve style is possible.
The present invention is further described with the examples and comparative examples as follows. In the examples, the properties are measured according to the following methods.
Outer water retention rate (%)=(w2−w1)/(W2−W1)×100
Inner water retention rate (%)=(w4−w3)/(W2−W1)×100
Ratio of outer/inner water retention rate=Outer water retention rate (%)/Inner water retention rate (%)

T-shirts or POLO shirts are made by using the water-absorbent quick-drying knitted fabric described in Examples 1-19.
Based on Example 1 and Example 10, it can be seen by comparing a fabric made of cross knitted long-fiber yarns with a fabric made of cross knitted short-fiber yarns that the larger the convex height in the reverse side is, the smaller the distance between adjacent convex parts is, the better the quick drying property is (a larger ratio of outer/inner water retention rate, and a smaller inner water retention rate).
Based on Example 2, Example 3, and Example 17, it can be seen that the higher the CR value of the polyester elastic fiber (as the convex fiber) is, the larger the convex height in the reverse side is, and the smaller the distance between adjacent convex parts is, the better the quick drying property is (a larger ratio of outer/inner water retention rate, and a smaller inner water retention rate).
Based on Example 14 and Example 7, and Example 15 and Example 9, it can be seen that when the cross knitted yarns contain no hydroscopic fibers such as viscose or nylon, the quick drying property is relatively better (a larger ratio of outer/inner water retention rate, and a smaller inner water retention rate).
Based on Example 11 and Example 15, it can be seen that the smaller the monofilament fineness of the long fiber forming the cross knitted yarns is, the better the quick drying property of the obtained fabric is (a larger ratio of outer/inner water retention rate, and a smaller inner water retention rate).
Based on Comparative Example 1 and Example 16, Comparative Example 2 and Example 17, it can be seen that when the reverse side of the fabric has no concave-convex structure, or when the convex height of the concave-convex structure is less than 40 μm, the quick drying property is poorer (a smaller ratio of outer/inner water retention rate, and a larger inner water retention rate).
It can be seen from Table 2 that a double sided knitted fabric obtained by using the same yarns has poorer quick-drying property than the single-sided knitted fabric of the present invention (a smaller ratio of outer/inner water retention rate, and a larger inner water retention rate), and has larger gram weight.
It can be seen from Table 3 that in comparative examples 4, 5, 6, and 7, although the reverse side is the concave-convex structure, because the fiber forming the convex parts is PET FDY (non-elastic PET), PET DTY (non-elastic PET), nylon, or cotton, the convex height in the reverse side cannot reach 40 μm, the quick drying property of the obtained fabric is not ideal (a smaller ratio of outer/inner water retention rate, and a larger inner water retention rate).
