Description

Technical Field

[0001] The invention relates to the technical field of textiles, and in particular to a washable textured wrinkled silk or silk-containing fabric and a preparation process and application thereof. Background Art

[0002] In recent years, with the rapid economic development, people's living standards and consumption levels have been continuously improving, and the textile industry has been constantly updating and iterating to meet consumers' demand for new products in the clothing, underwear and bedding markets.

[0003] At present, due to the special thermoplastic characteristics of chemical fiber products such as nylon and polyester, the fabrics can present various styles of texture wrinkles through wrinkling and high-temperature shaping processes, which are very popular in the market, especially for female consumers. Silk enjoys the reputation of "Queen of Fibers". The silk fabric made of it is light, smooth, soft and skin-friendly, with good moisture absorption and breathability and soft luster. It has always been widely loved as a high-end textile fabric, and its skin feel and comfort have advantages that other fibers cannot achieve. However, silk fiber itself is relatively soft. Although it is easy to wrinkle during wearing, it will basically flatten and disappear after washing. In addition, silk is not a thermoplastic material. It is difficult to truly form a permanent texture wrinkle style after wrinkling through heat shaping.

[0004] At present, there are various kinds of silk wrinkle fabrics on the market, such as double crepe, seersucker, georgette, etc., but they are all achieved through yarn twisting or special weaving processes. For example, the Chinese patent with publication number CN116005319A discloses a silk fabric and weaving method that can maintain strip wrinkles. It uses interval-set wrinkle lines to partially gather the fabric body to form strip wrinkles. During use, the setting of the wrinkle lines prevents the wrinkles formed from disappearing and fading. But overall, the wrinkles formed by this weaving wrinkling method are relatively regular and three-dimensional, unnatural, and the transition between the wrinkled and non-wrinkled areas is not soft enough. It is two completely different styles from the high-temperature wrinkling of chemical fiber fabrics. Although chemical fiber texture wrinkle fabrics have the advantages of being durable, not easy to deform, and easy to wash, the material itself has poor moisture absorption and air permeability, and the comfort of wearing is far less than that of natural fibers.

[0005] Therefore, how to superimpose various wrinkle styles on high-end silk fabrics has become one of the current research directions of the silk industry. Summary of the invention

[0006] The purpose of the present invention is to provide a washable textured wrinkled silk or silk-containing fabric, which solves the problem that the wrinkles formed by the weaving wrinkling method of the existing silk fabric are relatively three-dimensional and regular, unnatural, and the texture wrinkles formed by the high-temperature wrinkling process cannot be fixed, are not washable, and the wrinkles are easy to fade and disappear after washing. The fabric is skin-friendly, soft, smooth and comfortable, breathable and not stuffy, and also has a lasting non-continuous irregular texture wrinkle style, and still maintains a good texture wrinkle style after multiple washings. In addition, the present invention also provides a processing process for silk or silk-containing fabrics with a simple and efficient process flow, wide applicability, and the ability to form a lasting washable texture wrinkle style, and the fabric is applied in the fields of clothing, underwear, home textiles, etc.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions:

[0008] A first aspect of the present invention provides a washable wrinkled silk or silk-containing fabric, wherein the surface of the silk or silk-containing fabric has discontinuous and irregular wrinkles, and the discontinuous and irregular wrinkles are washable and shape-retaining, and the wrinkles will not disappear or deform after multiple washings.

[0009] Furthermore, the silk or silk-containing fabric includes 100% silk fabric, silk interwoven fabric with a silk content of more than 30%, or silk blended fabric.

[0010] Preferably, 100% silk fabric or silk interwoven fabric with a silk content of more than 30% is selected.

[0011] Furthermore, the length of the non-continuous and irregular texture wrinkles on the washable texture wrinkled silk or silk-containing fabric does not exceed 100 cm, and the average length is 0.5 to 10 cm (the average length is the average of the lengths of 30 randomly selected creases).

[0012] The second aspect of the present invention provides a process for preparing the above-mentioned washable wrinkled silk or silk-containing fabric, comprising the following steps:

[0013] S1. Pretreatment of additives:

[0014] The silk or silk-containing fabric is rolled or soaked in an auxiliary agent solution, and then the rolled or soaked fabric is subjected to a heating and setting treatment, and the rolling rate is 40 to 100%;

[0015] The mass content of the additive in the additive solution is 0.5 to 100 g / L, preferably 2 to 20 g / L, and the additive is one or more of polyurethane, polycarbonate, and silicone additive;

[0016] S2, Crumpling treatment:

[0017] The silk or silk-containing fabric treated in step S1 is subjected to a wrinkling treatment to form non-continuous and irregular texture wrinkles on the surface of the fabric;

[0018] S3, finalization processing:

[0019] The silk or silk-containing fabric after the wrinkle treatment in step S2 is rolled or soaked in a post-setting liquid for secondary heating and setting treatment, and then washed with water and dried to set the wrinkles on the fabric into permanent wrinkles;

[0020] The setting liquid contains a penetrant, an inorganic metal salt and an alkali agent.

[0021] Using the above preparation process:

[0022] Since silk fabrics or silk-containing fabrics are relatively soft, wrinkles formed on the surface are relatively easy to recover. In the present invention, a polymer auxiliary agent is used to pre-treat the silk fabrics or silk-containing fabrics, which reacts and solidifies on the surface of the fabrics, making the silk fabrics or silk-containing fabrics relatively stiff, and it is easier to form wrinkles on the surface of the fabrics during the subsequent wrinkling treatment, and the wrinkles are not easy to recover. However, the fabrics after the auxiliary agent pre-treatment and the wrinkling treatment cannot be washed. If the fabrics are washed at this time, the wrinkles formed on the surface of the fabrics cannot be effectively maintained. Therefore, the present application also adopts a shaping treatment process to shape the texture wrinkles formed on the surface of the fabrics into permanent wrinkles. During the shaping treatment process, the silk is treated with alkali to make it easier to moisturize, and then the inorganic metal salt enters the interior of the silk fiber and bonds with the active group to shape the silk. At the same time, an appropriate amount of penetrant can be added to make the inorganic metal salt easier to enter the interior of the silk fiber, which helps to completely shape the wrinkles.

[0023] After the silk or silk-containing fabrics are pre-treated with the auxiliary agent → machine wrinkling → shaping treatment → washing, dyeing and finishing process, they still have a smooth, breathable, soft and comfortable feel, and non-continuous and irregular texture wrinkles are formed on the fabric, and the wrinkles are natural. Moreover, the fabric can still maintain the non-continuous and irregular texture wrinkle style after 10 washings.

[0024] Furthermore, in step S3, the mass content of the penetrant is 0.5-20 g / L, the mass content of the inorganic metal salt is 0.1-50 g / L, the content of the alkali agent is 0.5-20 g / L, and the bath ratio is 1:5-1:50.

[0025] Specifically, the penetrant is TF-107D (Zhejiang Chuanhua Chemical Industry); the inorganic metal salt is sodium sulfate; and the alkali agent is sodium carbonate.

[0026] Furthermore, in the step S1, the primary heating and shaping treatment adopts steam heating and shaping or hot air shaping.

[0027] Furthermore, the processing temperature of steam heating setting is 100-140°C, and the processing time is 1-60 minutes; the processing temperature of hot air setting is 100-140°C, and the processing time is 1-5 minutes.

[0028] Since the curing of the additive on the surface of the fabric requires a certain temperature and time, however, if the temperature is too high, the silk fabric will turn yellow easily, affecting the appearance. If the treatment time is too long, there is also a risk of affecting the strength and color of the silk. Therefore, in the process of heating and setting, the heating temperature is controlled between 100 and 140°C, steam heating is achieved by using water vapor over 100°C, the steam heating setting treatment time is controlled between 1 and 60 minutes, and the hot air setting treatment time is controlled between 1 and 5 minutes.

[0029] Furthermore, in step S3, the temperature of the secondary heating and shaping treatment is set to 30-100° C., and the treatment time is 10-60 min.

[0030] The secondary heating setting treatment also has requirements for temperature and time. Combined with the components selected in the setting liquid and the setting principle of this step, the temperature of the secondary heating setting treatment is set to 30-100°C, and the treatment time is 10-60 minutes. Too low temperature in the bath setting treatment is not conducive to the effect of penetrant treatment on silk, etc. Too high temperature may damage the silk fabric. Too short treatment time has limited effect. Too long treatment time may also damage the silk fabric.

[0031] Furthermore, a crumpling treatment process: a machine crumpling treatment method can be used to form non-continuous and irregular texture wrinkles on the surface of the fabric.

[0032] Furthermore, after the shaping treatment, the silk or silk-containing fabric is post-treated, and the post-treatment process includes washing, dyeing and finishing.

[0033] Washing process: Wash the fabric with washing solution, and then rinse it several times with room temperature tap water. The washing temperature is 20-80℃ and the washing time is 10-60min.

[0034] The washing solution includes 0.5-20 g / L of soaping agent sodium stearate and 0.5-5 g / L of anti-ash oil GD-62, which can greatly improve the feel and air permeability of silk fabrics.

[0035] Dyeing-finishing process: Ordinary acid dyeing or reactive dyeing conditions are sufficient. Depending on the type of fabric, it can be softened or have other functionalities such as waterproofing and UV resistance added during the finishing stage.

[0036] The third aspect of the present invention provides an application of washable textured wrinkled silk or silk-containing fabrics. The washable textured wrinkled silk or silk-containing fabrics prepared by the above process are used to process clothing (such as women's shirts, jackets, trousers, skirts), underwear and home textile products.

[0037] Compared with the prior art, the present invention has the following beneficial effects:

[0038] (1) After being treated by this process, the silk or silk-containing fabric still has a smooth, breathable, soft and comfortable feel. Discontinuous and irregular texture wrinkles are formed on the fabric, and the wrinkles are natural. Moreover, the fabric can still maintain the style of discontinuous and irregular texture wrinkles after being washed 10 times.

[0039] (2) Since silk fabrics or silk-containing fabrics are relatively soft, wrinkles formed on the surface are relatively easy to recover. In the present invention, a polymer additive is used to pre-treat the silk fabrics or silk-containing fabrics, which reacts and solidifies on the surface of the fabrics, making the silk fabrics or silk-containing fabrics relatively stiff. The pre-treated silk or silk-containing fabrics are more easily squeezed into non-continuous and irregular wrinkles, and have better retention.

[0040] (3) However, the fabric after the auxiliary agent pre-treatment and the wrinkle pressing treatment cannot be washed yet. If the fabric is washed at this time, the wrinkles formed on the surface of the fabric cannot be effectively maintained. Therefore, the present application also adopts a shaping treatment process to shape the texture wrinkles formed on the surface of the fabric into permanent wrinkles. During the shaping treatment process, the silk is treated with alkali to make it easier to moisturize, and then the inorganic metal salt enters the interior of the silk fiber and bonds with the active groups to shape the silk. At the same time, an appropriate amount of penetrant can be added to make it easier for the inorganic metal salt to enter the interior of the silk fiber, which helps to completely shape the wrinkles. The wrinkles can be effectively maintained after dyeing and washing in the later stage. BRIEF DESCRIPTION OF THE DRAWINGS

[0147] The process for forming a washable texture wrinkle comprises the following steps:

[0148] S1. Pretreatment of additives:

[0149] The fabric was dipped into a 2g / L polyurethane solution, the liquid rate was controlled at 80%, and the dipped fabric was then dried with hot air at 130°C for 2 minutes.

[0157] S5. Dyeing treatment:

[0158] Ordinary acid stain.

[0159] The surface of the finished fabric of Example 8 forms clear and natural non-continuous and irregular texture wrinkles. After being washed 10 times, the fabric can still maintain the clear non-continuous and irregular texture wrinkle style. The fabric is soft, skin-friendly, breathable and smooth.

[0160] Comparative Example 1

[0161] Comparative Example 1 is a comparative test example of Example 1, and the difference between it and Example 1 is that:

[0162] The S3-setting treatment step is missing in this comparative example.

[0163] Although the surface of the finished fabric of Comparative Example 1 has texture wrinkles, the wrinkles are unclear and unnatural, the folds are shallow, and it is not suitable for washing. After washing once, the texture wrinkles disappear and the fabric surface becomes smooth.

[0164] Comparative Example 2

[0165] Comparative Example 2 is a comparative test example of Example 1, and the difference between it and Example 1 is that:

[0166] The S1-auxiliary agent pre-treatment step is missing in this comparative example.

[0167] The surface of the finished fabric of Comparative Example 2 cannot form texture wrinkles, or the texture wrinkles formed are particularly unclear and unnatural, the folds are particularly shallow, and the texture wrinkles disappear after washing once, and the fabric surface becomes smooth.

[0168] Figure 1 A is a physical picture of the finished fabric obtained in Example 1. Evenly distributed, clear and natural non-continuous irregular texture wrinkles are formed on the fabric, and the creases are clear and obvious, and the transition between the wrinkled and non-wrinkled areas is soft. Figure 1 B is a real picture of the finished fabric obtained in Example 1 after being washed 10 times. Although the creases of the texture wrinkles become lighter after being washed 10 times, the fabric can still maintain the non-continuous random texture wrinkle style.

[0169] Figure 2 A is a physical picture of the finished fabric obtained in Comparative Example 1. Although texture wrinkles are formed on the fabric, the wrinkles are unclear and uneven, and the creases are shallow. Figure 2 B is a real picture of the finished fabric prepared in comparative example 1 after being washed once. After washing once, the texture wrinkles on the fabric disappear and the fabric surface becomes smooth.

[0170] In Comparative Example 1, only the fabric is pre-treated with an auxiliary agent and then subjected to a wrinkle pressing treatment. Although wrinkles can be formed on the fabric, since the wrinkles formed on the fabric are not subjected to a shaping treatment, the wrinkles formed on the fabric cannot be effectively maintained during subsequent washing and dyeing treatments. Therefore, although texture wrinkles are formed on the finished fabric obtained in Comparative Example 1, the wrinkles are not clear, the creases are shallow, and the fabric is not resistant to water washing. After washing once, the texture wrinkles on the fabric disappear and the fabric surface becomes smooth.

[0171] Figure 3 A is the finished fabric obtained in Comparative Example 2, on the surface of which no texture wrinkles can be formed or the texture wrinkles formed are particularly unclear and uneven, and the creases are particularly shallow. Figure 3 B is a real picture of the finished fabric obtained in Comparative Example 2 after being washed once. After washing once, the texture wrinkles on the fabric disappeared and the fabric surface became smooth.

[0172] In Comparative Example 2, the fabric was not pre-treated with auxiliary agents, and the fabric was directly subjected to wrinkle pressing and shaping treatment. Because the fabric is relatively soft, wrinkles can be formed on the surface of the fabric by direct wrinkle pressing treatment. However, even after shaping treatment, the wrinkles on the fabric are relatively easy to recover, especially after subsequent washing and dyeing treatments, resulting in the wrinkles on the fabric cannot be effectively maintained. Therefore, the texture wrinkles formed on the finished fabric prepared in Comparative Example 2 are particularly unclear and unnatural, the creases are particularly shallow, and it is not resistant to water washing. After washing once, the texture wrinkles on the fabric disappear and the cloth surface becomes smooth.

[0173] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
