Description

Technical Field

[0001] The present invention relates to the field of textiles, and in particular to a finishing and dyeing method for unidirectional moisture-conducting knitted fabrics. Background Art

[0002] One-way moisture-conducting knitted fabric is a high-value functional fabric that can conduct moisture in one direction and is waterproof, and is usually used in the production of sports shoes. One-way moisture-conducting knitted fabric has a sandwich structure, including a waterproof surface layer, a connecting layer and a water-absorbent bottom layer; the surface layer of this structure is generally woven with moisture-absorbing and perspiration-wicking yarn, and the bottom layer is woven with load-effect yarn. Due to the different properties of the surface and bottom yarns that constitute the fabric, the waterproofness of the surface layer or the moisture conductivity of the bottom layer will decrease during the simultaneous finishing or dyeing process, which is lower than that of fabrics woven with a single yarn. Summary of the invention

[0003] In view of the above problems, the present application provides a finishing and dyeing method suitable for unidirectional moisture-conducting knitted fabrics, which can improve the waterproofness and / or moisture conductivity of the fabric and improve the economic value of the fabric.

[0004] The first aspect of the present invention provides a finishing method for a unidirectional moisture-conducting knitted fabric, comprising the following steps: pre-treatment, pre-treatment, post-treatment, first setting and second setting; in the first setting step, the setting temperature is controlled at 150-170°C; in the second setting step, the setting temperature is controlled at 120-150°C, and 0.5-1.0% moisture-absorbing quick-drying auxiliary agent is added; the unidirectional moisture-conducting knitted fabric is a sandwich structure, comprising a surface layer, a connecting layer and a bottom layer, the surface layer is woven with moisture-absorbing and perspiration-wicking yarn, the bottom layer is woven with a polytetrafluoroethylene-containing load-effect yarn, and the connecting layer is a chemical fiber monofilament that connects the surface layer and the bottom layer.

[0005] The study found that during the finishing or dyeing process, the waterproofness of the surface layer or the moisture conductivity of the bottom layer will decrease, lower than that of fabrics woven from a single yarn. This is mainly because the addition of moisture-absorbing and quick-drying additives in the finishing process will interfere with and affect the waterproof structure formed by the load-effect yarn.

[0010] Furthermore, the one-way moisture-conducting knitted fabric is a sandwich structure, including a surface layer, a connecting layer and a bottom layer. The surface layer is woven with moisture-absorbing and perspiration-releasing yarn, the bottom layer is woven with a charge-effective yarn containing tetrafluoroethylene, and the connecting layer is a chemical fiber monofilament that connects the surface layer and the bottom layer.

[0011] The second aspect of the present invention provides a dyeing and finishing method for a unidirectional moisture-conducting knitted fabric, comprising the following steps: pre-setting, pre-treatment, dyeing, post-treatment, first setting and second setting; in the first setting step, the setting temperature is controlled at 150-170°C; in the second setting step, the setting temperature is controlled at 120-150°C, and 0.5-1.0% moisture-absorbing quick-drying auxiliary agent is added; the unidirectional moisture-conducting knitted fabric is a sandwich structure, comprising a surface layer, a connecting layer and a bottom layer, the surface layer is woven with moisture-absorbing and perspiration-releasing yarn, the bottom layer is woven with a polytetrafluoroethylene-containing charge-effect yarn, and the connecting layer is a chemical fiber monofilament that connects the surface layer and the bottom layer.

[0013] Furthermore, the dyeing process lasts for 30-50 minutes at a temperature of 110-130°C.

[0014] Furthermore, the predetermined process has a temperature of 170°C-190°C and a vehicle speed of 20-30M / min; the pre-treatment process includes adding 1.0-3.0g / L of refining agent, 0.5-1.5g / L of flake caustic soda and 1-1.5g / L of cylinder cleaning agent, with a bath ratio of 1:15-20, and continuing at 80-90°C for 30-40 minutes.

[0015] Furthermore, the post-treatment process includes a reduction washing step and a soap washing step; in the reduction washing step, 1-1.5 g / L of caustic soda flakes and 2-4 g / L of hydrosulfur powder are added, the bath ratio is 1:10-15, and the temperature is 80-90°C; in the soap washing step, 0.5-1.5 g / L of caustic soda flakes and 0.5-1.5 g / L of cylinder cleaning agent are added, the bath ratio is 1:10-15, and the temperature is 65-75°C.

The embodiments described herein are only used to more clearly illustrate the technical solutions of the present application, and are therefore only used as examples, and cannot be used to limit the scope of protection of the present application.

[0020] Reference to "embodiment" herein means that the specific features, structures or characteristics described in conjunction with the embodiment may be included in at least one embodiment of the present application. The term "embodiment" appearing in various places in the specification does not necessarily refer to the same embodiment, nor does it particularly limit its independence or association with other embodiments. In principle, in the present application, as long as there is no technical contradiction or conflict, the various technical features mentioned in the embodiments can be combined in any way to form a corresponding implementable technical solution.

[0021] Unless otherwise defined, the technical terms used in this document have the same meanings as those generally understood by those skilled in the art to which this application belongs; the use of relevant terms in this document is only for describing specific embodiments and is not intended to limit this application.

[0022] In the description of this application, the term "and / or" is an expression used to describe the logical relationship between objects, indicating that three relationships may exist, for example, A and / or B, which means: A exists, B exists, and A and B exist at the same time. In addition, the character " / " in this article generally indicates that the objects before and after are in an "or" logical relationship.

[0023] In the present application, terms such as “first” and “second” are merely used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship of quantity, priority or sequence between these entities or operations.

[0024] Without further limitations, in this application, the words "include", "comprises", "has" or other similar expressions used in the sentences are intended to cover non-exclusive inclusion. These expressions do not exclude the presence of additional elements in the process, method or product including the elements, so that the process, method or product including a series of elements may include not only those limited elements, but also other elements not explicitly listed, or also include elements inherent to such process, method or product.

[0025] Similar to the understanding in the Examination Guidelines, in this application, expressions such as "greater than", "less than", "exceed" and the like are understood to exclude the number itself; expressions such as "above", "below", "within" and the like are understood to include the number itself. In addition, in the description of the embodiments of this application, "multiple" means more than two (including two), and similar expressions related to "multiple" are also understood in this way, such as "multiple groups", "multiple times", etc., unless otherwise clearly and specifically limited.

[0026] The first aspect of the present invention provides a finishing method for a unidirectional moisture-conducting knitted fabric, comprising the following steps: pre-treatment, pre-treatment, post-treatment, first setting and second setting; in the first setting step, the setting temperature is controlled at 150-170°C; in the second setting step, the setting temperature is controlled at 120-150°C, and 0.5-1.0% moisture-absorbing quick-drying auxiliary agent is added; the unidirectional moisture-conducting knitted fabric is a sandwich structure, comprising a surface layer, a connecting layer and a bottom layer, the surface layer is woven with moisture-absorbing and perspiration-releasing yarn, the bottom layer is woven with a polytetrafluoroethylene-containing load-effect yarn, and the connecting layer is a chemical fiber monofilament that connects the surface layer and the bottom layer.

[0027] The study found that during the finishing or dyeing process, the waterproofness of the surface layer or the moisture conductivity of the bottom layer will decrease, lower than the fabric woven with a single yarn. This is mainly because the addition of moisture-absorbing and quick-drying additives in the finishing process will interfere with and affect the waterproof structure formed by the load-effect yarn. Moisture-absorbing and perspiration-wicking yarn is a special-section yarn. Through the moisture-wicking structure of the grooves of the special-section, it absorbs moisture and evaporates it into the air to achieve a certain absorption and drainage effect, while the moisture-absorbing and quick-drying additive plays an auxiliary role. The moisture-absorbing and perspiration-wicking agent contains small molecular polymers with polar groups to form a hydrophilic film, and the polar groups will interact with functional groups such as hydroxyl or amino groups in the fiber, so that the film can absorb and conduct moisture in the fiber.

[0028] Different from the prior art, the finishing method of the unidirectional moisture-conducting knitted fabric provided by the present technical scheme adopts two setting processes; in the first setting process, the setting temperature is controlled at 150-170°C, so that the tetrafluoroethylene on the surface of the lotus-effect yarn forms a lotus needle-like fluff to achieve the waterproofness of the base layer; in the second setting process, the moisture-absorbing and quick-drying auxiliary agent is added to enhance the moisture absorption and discharge function of the moisture-absorbing and sweat-wicking yarn without affecting the waterproofness of the base layer.

[0029] Furthermore, the predetermined process has a temperature of 170° C.-190° C. and a machine speed of 20-30 M / min. The predetermined process improves the flatness of the fabric.

[0030] Furthermore, in the pre-treatment process, 1.0-3.0 g / L of scouring agent, 0.5-1.5 g / L of caustic soda flakes and 1-1.5 g / L of cleaning agent are added, with a bath ratio of 1:15-20, and the temperature is 80-90°C for 30-40 minutes. If the temperature of this process is less than 80°C, the oil removal will not be clean, and if the temperature is greater than 90°C, the waterproof performance of the fabric will be reduced.

[0031] Furthermore, the post-treatment process includes a reduction washing step and a soap washing step; in the reduction washing step, 1-1.5 g / L of caustic soda flakes and 2-4 g / L of hydrosulfur powder are added, the bath ratio is 1:10-15, and the temperature is 80-90°C; in the soap washing step, 0.5-1.5 g / L of caustic soda flakes and 0.5-1.5 g / L of cylinder cleaning agent are added, the bath ratio is 1:10-15, and the temperature is 65-75°C.

[0032] This step removes excess PTFE from the fabric. During weaving and the previous steps, the PTFE on the wicking yarn will fall off and migrate to the moisture wicking yarn, affecting its water absorption.

[0033] The second aspect of the present invention provides a dyeing and finishing method for a unidirectional moisture-conducting knitted fabric, comprising the following steps: pre-setting, pre-treatment, dyeing, post-treatment, first setting and second setting; in the first setting step, the setting temperature is controlled at 150-170°C; in the second setting step, the setting temperature is controlled at 120-150°C, and 0.5-1.0% moisture-absorbing quick-drying auxiliary agent is added; the unidirectional moisture-conducting knitted fabric is a sandwich structure, comprising a surface layer, a connecting layer and a bottom layer, the surface layer is woven with moisture-absorbing and perspiration-releasing yarn, the bottom layer is woven with a polytetrafluoroethylene-containing charge-effect yarn, and the connecting layer is a chemical fiber monofilament that connects the surface layer and the bottom layer.

[0034] Different from the prior art, the dyeing and finishing method of the unidirectional moisture-conducting knitted fabric provided by the present technical scheme adopts two setting processes; in the first setting process, the setting temperature is controlled at 150-160°C, so that the tetrafluoroethylene on the surface of the lotus-effect yarn forms a lotus needle-like fluff to achieve the waterproofness of the base layer; in the second setting step, the moisture absorption and quick-drying auxiliary agent is added to enhance the moisture absorption and discharge function of the moisture-wicking yarn without affecting the waterproofness of the base layer.

[0035] Furthermore, the dyeing process lasts for 30-50 minutes at a temperature of 110-130°C.

[0036] Furthermore, the predetermined process has a temperature of 170° C.-190° C. and a machine speed of 20-30 M / min. The predetermined process improves the flatness of the fabric.

[0037] Furthermore, in the pre-treatment process, 1.0-3.0 g / L of scouring agent, 0.5-1.5 g / L of caustic soda flakes and 1-1.5 g / L of cleaning agent are added, with a bath ratio of 1:15-20, and the temperature is 80-90°C for 30-40 minutes. If the temperature of this process is less than 80°C, the oil removal will not be clean, and if the temperature is greater than 90°C, the waterproof performance of the fabric will be reduced.

[0038] Furthermore, the post-treatment process includes a reduction washing step and a soap washing step; in the reduction washing step, 1-1.5 g / L of caustic soda flakes and 2-4 g / L of hydrosulfur powder are added, the bath ratio is 1:10-15, and the temperature is 80-90°C; in the soap washing step, 0.5-1.5 g / L of caustic soda flakes and 0.5-1.5 g / L of cylinder cleaning agent are added, the bath ratio is 1:10-15, and the temperature is 65-75°C.

[0039] This step removes excess PTFE from the fabric. During weaving and the previous steps, the PTFE on the wicking yarn will fall off and migrate to the moisture wicking yarn, affecting its water absorption.

[0040] In this embodiment, the unidirectional moisture-conducting knitted fabric is a sandwich structure, including a surface layer, a connecting layer and a bottom layer, the surface layer is woven with moisture-absorbing and sweat-wicking yarn, the bottom layer is woven with a charge-effective yarn containing tetrafluoroethylene, and the connecting layer is a chemical fiber monofilament that connects the surface layer and the bottom layer. The moisture-absorbing and sweat-wicking yarn is a non-elastic chemical fiber with a special cross-section.
