Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of fabrics, specifically it is a kind of intelligent quick-drying fabric with good wet-state dimensional stability, and air permeability changes with the moisture content of fabric. BACKGROUND

[0002] With the improvement of living standards, consumers have higher and higher requirements for the comfort of clothing. Traditional yarns and fabrics often do not meet the requirements in terms of moisture absorption and sweat-wicking performance. Although the cross-section of the yarn can be changed, the number of yarn fibers can be increased, or moisture absorption and sweat-wicking aids can be added to achieve traditional moisture absorption and sweat-wicking, the fabric can quickly absorb the sweat on the surface of the human body, but it will not be saturated with the absorption of sweat, and the air permeability and moisture permeability of the fabric will not increase. It is easy for the wearer to feel hot and uncomfortable in the movement or hot environment.

[0003] Patent CN 118345551 A discloses a moisture-absorbing quick-drying fabric, which includes a face yarn and a first ground yarn. The face yarn and the first ground yarn are woven to form a plaited plain weave. The face yarn is a blended yarn made of cotton fibers and hollow polyester fibers. The first ground yarn is an elastic filament. The fabric obtained by weaving the first ground yarn with the face yarn has good elasticity. The first cotton fiber blended yarn is woven with the hollow polyester fiber and the first pure cotton fiber. The first pure cotton fiber has strong moisture absorption. It is a porous material with irregular molecular arrangement and contains a large number of hydrophilic structures. The hollow polyester fiber is a new type of hollow structure with a complex and continuous pore structure and a groove channel. The hollow structure enhances the capillary effect of the fabric when it absorbs water. The patent uses cotton and porous polyester fibers with high moisture absorption to absorb sweat on the surface of the fabric. However, the air permeability and moisture permeability of the fabric do not increase during the absorption of sweat. When the sweat output of the human body increases further, the excess sweat cannot be quickly discharged, resulting in a feeling of stuffiness and discomfort.

[0004] In recent years, material science has made great progress, providing technical support for the development of intelligent quick-drying fabric with good wet-state dimensional stability and air permeability that changes with the moisture content of the fabric. This fabric can better absorb the sweat excreted by the human body. As the sweat is absorbed, the length of the moisture-absorbing deformation yarn in the fabric gradually increases, the partial voids of the fabric open, the air permeability and moisture permeability of the fabric increase, and the water can be quickly discharged from the skin surface, greatly improving the comfort of wearing.

[0026] As shown in Figure 1 and 2 , an intelligent quick-drying fabric comprises a fabric body, the fabric body is woven by at least two different performance yarns including yarn A and yarn B, the yarn A is a moisture absorption deformation characteristic yarn, and the yarn B is a yarn that does not deform after moisture absorption. The yarn B plays a role in stabilizing the size of the fabric after moisture absorption, and the yarn A is elongated after moisture absorption to make the gap larger, increase the air permeability, accelerate the evaporation effect of moisture, and achieve the purpose of quick drying.

[0027] The fabric body comprises a plurality of basic cycle unit structures, and is composed of a plurality of basic cycle unit structures. In a basic cycle unit structure, the yarn A is woven to form a complete A loop course 5, the A loop course 5 comprises A loops, the yarn B is interwoven around the yarn A m and the yarn B m+n , the yarn B m is woven to form a B m loop course 4, the B m loop course 4 comprises B m loops, and the yarn Bm+n woven yarn B m+n stitch row 6, yarn B m+n stitch row 6 contains yarn B m+n stitch, B m stitch row and B m+n stitch row, B, is separated by n-1 stitch rows m stitch row 4 and B m+n stitch row 6 is interlaced into loops on at least one stitch column, and m and n are both natural numbers greater than 0. Yarn A cannot be woven into a stitch row alone, such as a basic loop unit structure having 3 stitches in a stitch row, yarn A only forms 2 stitches or 1 stitch when woven, without completing 3 stitches. Yarn B is completely woven into a stitch row.

[0028] the B m stitch row and B m+n stitch row is interlaced into loops on at least two stitch columns, and the distance between two adjacent interlaced stitch columns is k stitch columns, so that yarn B m and yarn B m+n forms a rectangular frame structure, wherein the width of the rectangular frame structure is 0 Figure 1 and 2 as shown, 4 stitch columns and 3 stitch rows, yarn B m and yarn B m+n are interlaced into loops on the first left and last right stitch columns, thereby forming an approximate rectangular frame structure up, down, left and right. Yarn A is interlaced into loops with the middle two stitch columns.

[0029] the moisture absorption of yarn A is 1%-20% in the length direction, and almost no elongation in the diameter direction, and returns to the original length after drying.

[0030] the proportion of the amount of yarn A to the total amount of main yarn of the fabric is less than or equal to 40%, and the proportion of the amount of yarn B to the total amount of main yarn of the fabric is greater than or equal to 60%, to ensure the stability of the fabric.

[0031] the yarn B is any one or a combination of more than one of polyester fiber, polyamide 66 fiber, polyamide 6 fiber, modified polyester fiber, polypropylene fiber, cotton, lyocell and modal.

[0032] by adjusting the amount of yarn A and yarn B, the dimensional change rate of the main fabric after moisture absorption is less than 8%, that is, even in the case of the maximum water content, the dimensional change rate of the main fabric will not exceed 8%, to ensure that the fabric will not be difficult to restore to the initial state due to excessive change.

[0033] The fabric body is a knitted fabric, satisfying the use requirement.

[0034] In addition, the fabric body further comprises elastic yarn C which is integrally knitted with the yarn A and the yarn B, so as to improve the elasticity of the fabric body.

[0035] When the fabric absorbs moisture, the loops knitted by the yarn A are deformed according to the change of the water content of the fabric, and the air permeability of the fabric is automatically adjusted through different elongations; the yarn B plays a role in stabilizing the size of the fabric in the wet state of the fabric. When the fabric changes from the "dry-wet-dry" state, the yarn A with the moisture absorption and deformation characteristics is lengthened with the increase of the water content of the fabric, and the diameter is almost unchanged. The organization formed by the yarn A has a larger non-fullness coefficient and a larger gap, the air permeability and moisture permeability are increased, the water vapor on the surface of the human skin is discharged more quickly, the water on the surface of the skin is discharged more quickly, and the comfort of wearing is greatly improved; with the decrease of the water content of the fabric, the length of the yarn A is shortened, the diameter is unchanged, the non-fullness coefficient of the organization formed by the yarn A is smaller, the gap is smaller, the air permeability is reduced, and the heat preservation effect is achieved.

[0036] The following is described by taking an example.

[0037] 1. Selection of yarns:

[0038] The A yarn is selected from the yarn PA6 30D / 12F / 1SD DTY with moisture absorption and deformation characteristics, the B yarn is selected from PA6 50D / 48F / 1FD DTY, and the C yarn is selected from Spandex 30D.

[0039] The A yarn plays a role in moisture absorption and elongation of the fabric, the B yarn plays a role in stabilizing the size of the fabric, and the C yarn increases the elasticity and comfort of the fabric.

[0040] 2. Machine type used:

[0041] The weft knitting single-jersey machine is a large circular machine with 44G and 34 inches.

[0042] 3. Weaving process

[0043]

[0044] 4. Dyeing and finishing treatment: washing, pre-setting, overflow dyeing, dehydration, and post-setting.

[0045] 5. Finished product parameters

[0046] Finished product specification: 152CM*150GSM.

[0047] The fabric obtained by the example is used as a sample cloth, and the performance of the fabric is tested.

[0048] I. The sample cloth is disassembled in the reverse weaving direction, and the moisture-absorbing and elongated yarn fibers are characterized in dry and wet states, the changes of fiber diameter and length are analyzed, and the reference Figure 3 and 4 As shown in the figure, by comparison, it is found that the fiber diameter of moisture-absorbing and elongated yarn A does not change before and after moisture absorption, and the length is elongated by about 10%. II.

[0050] Moisture absorption characterization and air permeability test are carried out, and the influence of yarn A on the air permeability of the sample cloth under different moisture absorption conditions and the change rule are analyzed through quantitative data.

[0051] Based on the weight of the fabric, according to the formula

[0052] W=n%×W0

[0053] In the test:

[0054] W is the water injection amount g,

[0055] n is the water content of the fabric %,

[0056] W0 is the weight of the fabric g,

[0057] After setting the relative humidity, the fabric W0=1.5g is set under the condition of relative humidity, and the following results are obtained Table 1:

[0058] Table 1

[0059]

[0060] After setting the relative humidity, the fabric is stored in a sealed condition under constant temperature and humidity for 24h, and the moisture in the fabric is uniformly diffused.

[0061] According to the national standard air permeability test of textiles, the fabric with humidity gradient set according to the standard GB / T 5453 Textile Fabric Air Permeability Test has been completed, and three groups of parallel data are obtained, and the results are as follows Table 2:

[0062] Table 2

[0063]

[0064] Referring to Figure 5 , it is an air permeability test diagram.

[0065] By implementing examples and experimental examples, referring to experimental results, the following conclusions are drawn: the design scheme of forming a stable rectangular structure by the hygroscopic and almost non-deformation yarn ensures that the hygroscopic and deformation yarn after deformation after hygroscopic minimizes the influence on the size stability of the fabric, the fabric has good size stability, the warp shrinkage rate of the fabric is-2% and the weft shrinkage rate is-2.5% measured by ISO 6330 Household Detergent and Drying Procedure for Textile Testing. With the gradual increase of the moisture content of the fabric, the yarn hygroscopic deformation elongation, the gap between the loops is expanded, the unfullness coefficient is increased, and the air permeability of the fabric is increased. However, due to the limited degree of yarn hygroscopic elongation, a peak value will be reached, at which time the air permeability of the fabric reaches a maximum value; with the increase of the hygroscopic amount, the gap between the loops is gradually filled with water molecules, and due to the pulling action of the surface tension of the water molecules, the connection between the loops is more closely, and the air permeability is greatly reduced. The data in the table show that when the hygroscopic amount of the fabric is 20%-40%, the air permeability will have a maximum value, and the peak will appear when the hygroscopic amount is about 30%. The moisture content continues to increase, and thereafter the air permeability of the fabric will continue to decrease, at which time the water molecules will play a role in hindering the flow of air. From the above test results, it can also be seen that for the hygroscopicity of the fabric, that is, the water content, it is not that the higher the water content, the greater the deformation of the yarn A and the better the air permeability, but there is a maximum value.

[0066] It should be noted that the above is only the preferred embodiment of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art can modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features, but any modification, equivalent substitution, improvement, etc. within the spirit and principles of the present application shall be included in the protection scope of the present application.
