[0002] Currently, conventional fabrics have room for further improvement in terms of comfort, safety, and functionality. Specifically, this is reflected in the following aspects;

[0003] Sweat backflow and stuffiness: After traditional fabrics become saturated with sweat, they only absorb and do not expel, causing sweat to accumulate in the skin contact layer, resulting in stuffiness and coldness.

[0004] Poor fabric safety: Some fabrics have problems such as unqualified pH value, which can easily cause skin allergies or irritation; some products have even been found to contain harmful substances such as decomposable carcinogenic aromatic amine dyes; chemical auxiliaries added to give the fabric antibacterial and other functions may themselves pose a risk of sensitization.

[0005] In summary, existing knitted fabrics have problems such as sweat backflow and stuffiness, and poor fabric safety.

[0006] In view of this, the present invention is proposed. Summary of the Invention

[0007] The purpose of the present invention is to propose a multifunctional modal polylactic acid knitted fabric and its preparation method to solve the problems of sweat backflow and stuffiness, and poor fabric safety of existing knitted fabrics.

[0013] The eighth, tenth, and twelfth rows are characterized by a loop, a floating stitch, a floating stitch, and a gathered loop.

[0014] The yarn in the first, third, fifth, seventh, ninth, and eleventh rows is polylactic acid filament, and the yarn in the second, fourth, sixth, eighth, tenth, and twelfth rows is modal yarn.

[0015] Further, the modal yarn has a thickness of 40~60S, and the polylactic acid filament has a thickness of 70~80D.

[0016] Further, the modal yarn has a yarn length of 255~295mm / 100 stitches, and the polylactic acid filament has a yarn length of 220~260mm / 100 stitches.

[0017] In a second aspect, the present invention provides a method for preparing a modal polylactic acid multifunctional knitted fabric, the method comprising any one of the modal polylactic acid multifunctional knitted fabrics described in any one of the inventions, the method comprising the following steps:

Through the capillary action between fibers, moisture is quickly transported from the high humidity area (modal layer) to the low humidity area (outer layer of fabric); through the fabric weaving pattern, the surface of the knitted fabric forms a raised dot pattern, which is essentially a three-dimensional water transport channel. The raised dot pattern not only increases the surface area to facilitate evaporation, but also forms a directional moisture conduction path from the inside to the outside of the fabric. In summary, modal yarn absorbs moisture, polylactic acid filaments wick away moisture, and the fabric weave pattern creates a textured, dotted pattern that wicks away moisture. This combination achieves a highly efficient cycle of "moisture absorption-moisture wicking-quick drying," fundamentally preventing sweat from remaining on the skin and backflow, completely solving the problems of stuffiness and coldness after exercise, and achieving true moisture absorption and quick drying.

[0035] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0036] Embodiment 1

[0037] Existing knitted fabrics have problems such as sweat backflow and stuffiness, and poor fabric safety.

[0038] To solve the above technical problems, this embodiment proposes a multifunctional modal polylactic acid knitted fabric, as shown in Figures 1 and 2. The knitted fabric has a double-sided four-needle knitting structure.

[0039] The fabric knitting pattern is a twelve-way cycle. The fabric knitting pattern is as follows:

[0040] The first, third, fifth, seventh, ninth, and eleventh rows are: purl needle with floating yarn, knit needle with loop, knit needle with loop, knit needle with loop;

[0041] The second, fourth, and sixth rows are: purl needle with loop, knit needle with floating yarn, knit needle with loop, knit needle with floating yarn;

[0042] The eighth, tenth, and twelfth rows are: purl needle with loop, knit needle with floating yarn, knit needle with floating yarn, knit needle with loop.

[0043] The yarn in the first, third, fifth, seventh, ninth, and eleventh rows is polylactic acid filament, and the yarn in the second, fourth, sixth, eighth, tenth, and twelfth rows is modal yarn.

[0044] The modal polylactic acid multifunctional knitted fabric described in this embodiment has the following beneficial effects:

[0045] First, the modal polylactic acid multifunctional knitted fabric described in this embodiment uses modal yarn as a regenerated cellulose fiber, which has excellent hydrophilicity and instant moisture absorption capacity; the modal yarn close to the skin layer can quickly capture sweat on the skin surface and keep the contact layer dry; polylactic acid is a bio-based biodegradable fiber with good hydrophobicity and wicking effect. Through the capillary action between fibers, moisture is quickly transported from the high humidity area (modal yarn layer) to the low humidity area (outer layer of fabric); through the fabric weaving pattern, the surface of the knitted fabric forms a raised dot pattern, which is essentially a three-dimensional water transport channel. The raised dot pattern not only increases the surface area to facilitate evaporation, but also forms a directional moisture conduction path from the inside to the outside of the fabric. In summary, modal yarn absorbs moisture, polylactic acid filaments wick away moisture, and the fabric weave pattern creates a textured, dotted pattern that wicks away moisture. This combination achieves a highly efficient cycle of "moisture absorption-moisture wicking-quick drying," fundamentally preventing sweat from remaining on the skin and backflow, completely solving the problems of stuffiness and coldness after exercise, and achieving true moisture absorption and quick drying.

[0046] II. The modal polylactic acid multifunctional knitted fabric described in this embodiment uses polylactic acid filaments as bio-based biodegradable fibers and modal yarns as regenerated cellulose fibers. Both polylactic acid filaments and modal yarns are environmentally friendly and renewable fibers, resulting in high fabric safety.

[0047] III. The modal polylactic acid multifunctional knitted fabric described in this embodiment not only has natural antibacterial and anti-mite properties, eliminating the need for highly polluting chemical post-treatment processes such as antibacterial finishing and anti-mite finishing, but also has natural UV resistance.

[0048] IV. The modal polylactic acid multifunctional knitted fabric described in this embodiment uses polylactic acid filaments that are weakly acidic, which matches the pH of healthy human skin. Therefore, it can greatly reduce skin irritation and truly achieve suitability for sensitive skin.

[0049] V. The Modal polylactic acid multifunctional knitted fabric described in this embodiment is characterized by its silky smoothness, softness, and drape, providing unparalleled comfort against the skin; the polylactic acid filament also has a good hand feel and a certain degree of elasticity; the combination of Modal yarn and polylactic acid filament results in a fabric that is skin-friendly, soft, and textured.

[0050] VI. The Modal polylactic acid multifunctional knitted fabric described in this embodiment has a cooling effect.

[0051] Specifically, the Modal yarn has a thickness of 50S, and the polylactic acid filament has a thickness of 75D.

[0052] Specifically, the Modal yarn has a thickness of 50S, and the polylactic acid filament has a specification of DTY75D / 72F. This setting results in a final fabric with a soft, smooth, elastic, and breathable feel.

[0053] More specifically, DTY stands for Draw Textured Yarn, which is a type of processed chemical fiber filament. It uses stretching and deformation processes to give the fiber fluffiness and elasticity, and is often used in textile fabrics to enhance softness and comfort. 72F indicates the number of monofilaments, meaning that the polylactic acid filament is composed of 72 monofilaments. The more monofilaments, the finer the fiber structure, the softer and smoother the fabric feels, the less prone to pilling, and the better the drape of the fabric.

[0054] Furthermore, the modal yarn has a yarn length of 275mm / 100 stitches, and the polylactic acid filament has a yarn length of 240mm / 100 stitches.

[0055] In a second aspect of this embodiment, a method for preparing a multifunctional modal polylactic acid knitted fabric is provided. The method includes any one of the modal polylactic acid multifunctional knitted fabrics described in the previous embodiment, and includes the following steps:

[0056] S1, weaving;

[0057] S2, dyeing;

[0058] S3, setting with a setting machine.

[0059] Further, in step S3, the setting temperature is 130°C, and the setting machine speed is 40 m / min.

[0060] Furthermore, in step S3, a softener is added during the setting process.

[0061] Since softeners are existing technology, they will not be described in detail here.

[0062] In this embodiment, the softener is a hand-feeling oil.

[0063] Furthermore, in step S2, reactive dyes are used to dye the modal yarn.

[0064] Since dyeing modal yarn with reactive dyes is existing technology, it will not be described in detail here.

[0065] Furthermore, in step S1, a 24G34'' (total 2544G) circular knitting machine is used for weaving. This equipment can ensure the efficiency and stability of weaving and is suitable for large-scale production.

[0066] Example 2

[0067] In this example, unlike Example 1, the modal yarn has a thickness of 40S, and the polylactic acid filament has a thickness of 70D.

[0068] Further, the modal yarn has a yarn length of 255 mm / 100 needles, and the polylactic acid filament has a yarn length of 2200 mm / 100 needles.

[0069] Example 3

[0070] In this example, unlike Example 1, the modal yarn has a thickness of 60S, and the polylactic acid filament has a thickness of 80D.

[0071] Further, the modal yarn has a yarn length of 295 mm / 100 needles, and the polylactic acid filament has a yarn length of 260 mm / 100 needles.

[0072] Performance Testing

[0073] The pH, antibacterial properties, cooling properties, and anti-mite properties of the modal polylactic acid multifunctional knitted fabrics described in Examples 1-3 were tested, and the results are shown in Table 1; the moisture absorption and quick-drying properties of the modal polylactic acid multifunctional knitted fabrics described in Examples 1-3 were tested, and the results are shown in Table 2; the moisture absorption and perspiration properties of the modal polylactic acid multifunctional knitted fabrics described in Examples 1-3 were tested, and the results are shown in Table 3; the skin adverse reaction evaluation of the modal polylactic acid multifunctional knitted fabrics described in Examples 1-3 was conducted, and the results are shown in Table 4.

[0074] Table 1 pH, antibacterial, cooling, and anti-mite performance tests of knitted fabrics

[0075]

[0076] As shown in Table 1, the pH value of the modal polylactic acid multifunctional knitted fabrics described in Examples 1-3 is 4.6, which is stably within the weakly acidic range of healthy skin and matches the pH of healthy human skin. Therefore, it can greatly reduce skin irritation and is suitable for sensitive skin.

[0077] As shown in Table 1, the antibacterial rate of the modal polylactic acid multifunctional knitted fabrics described in Examples 1-3 against Staphylococcus aureus, Escherichia coli, and three common bacteria is >82.0%, and this is the result after 50 washes. This strongly proves the natural and durable antibacterial function of polylactic acid filament fibers, without the need for finishing chemical auxiliaries, avoiding the contradiction of sensitization for antibacterial purposes.

[0078] As shown in Table 1, the mite-repellent rate of the modal polylactic acid multifunctional knitted fabric described in Examples 1-3 is >61.1%, proving that the knitted fabric has anti-mite properties. This is due to the natural anti-mite properties of polylactic acid filaments, which provides additional health protection.

[0079] As shown in Table 1, the contact cooling coefficient of the modal polylactic acid multifunctional knitted fabric described in Examples 1-3 is better than the national standard, proving that the knitted fabric has cooling properties. Combined with its rapid sweat evaporation capacity, it provides a continuous active cooling sensation for wearing during sports or in hot environments.

[0081]

[0082] Table 3 Instructions for testing the moisture absorption and perspiration wicking properties of knitted fabrics, page 6 / 8, CN 121428725 A

[0083]

[0084] As can be seen from Tables 2 and 3, the modal polylactic acid multifunctional knitted fabrics described in Examples 1-3 have excellent moisture absorption and quick-drying properties and moisture absorption and perspiration wicking properties. On the one hand, regardless of whether it is before or after washing, the soaking time is ≤2.9 seconds (reaching the highest standard of level 5), and the water absorption rate and diffusion speed also far exceed the standard requirements. This proves that the moisture is transferred instantly and cannot accumulate in the skin layer. On the other hand, the unidirectional transfer index does not decrease but increases after washing, from level 3 to level 5. This is a key highlight, indicating that the moisture-wicking structure of the fabric is more optimized or fluffy after washing, and the performance is durable, completely eliminating sweat backflow.

[0085] Table 4 Skin Adverse Reaction Evaluation Instructions for Knitted Fabrics 7 / 8 Page 9 CN 121428725 A

[0086]

[0087] As can be seen from Table 4, the Modal-polylactic acid multifunctional knitted fabrics described in Examples 1-3 are not prone to adverse skin reactions, proving that the fabric is extremely gentle on the skin and fully achieves the unity of safety and functionality.

[0088] Although the present invention is disclosed above, the present invention is not limited thereto. Any person skilled in the art can make various modifications and alterations without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope defined in the claims.
