Description

Technical Field

[0001] The present invention belongs to the field of textile technology, and particularly relates to an ultra-soft, light, warm fleece fabric and a preparation method thereof. Background Art

[0002] In today's society, with the continuous improvement of people's living standards and high requirements for quality of life, home clothing, as an indispensable part of daily life, has become the focus of consumers' attention in terms of comfort, functionality and aesthetics. Especially in the autumn and winter seasons, the market demand for home clothes that can effectively keep warm while being light and comfortable is growing. Although traditional autumn and winter suede home clothes are skin-friendly, wear-resistant, and not easy to fade, they are relatively soft and have poor thermal insulation properties. They often rely on heavy materials to achieve thermal insulation effects, which not only increases the wearer's physical burden and affects free movement, but also in the indoor heating environment, too thick clothing can easily cause imbalance in body temperature regulation and cause discomfort. What's worse, these materials are very easy to generate static electricity in dry climates, which is not only unpleasant, but may also cause irritation to wearers with sensitive skin.

[0003] Therefore, in order to meet people's multiple demands for autumn and winter home clothes such as "light, warm, soft, skin-friendly, and anti-static", it is necessary to provide a suede fabric with a cheese feel that is fine in fluff, super soft, has good thermal insulation, is light and anti-static, so as to solve the above technical problems.

[0004] However, most of the current antistatic raised fabrics are layered, for example, a woolen surface layer, a fabric base layer, an antibacterial layer, an antistatic layer, etc. This results in a thicker fabric with poor warmth retention, and only the surface layer has an antistatic effect, while the fabric base layer and the woolen surface layer do not have an antistatic effect. In addition, in the current preparation process of raised fabrics, most of them use a single napping machine to repeatedly nap the base fabric, which makes it difficult to control the uniformity and fineness of the nap, resulting in poor softness and durability of the nap morphology of the fabric, which will have an adverse effect on the subsequent use of the fabric and low efficiency. At the same time, when there is nap on the surface of the fabric, it will cause the fabric to have a certain degree of static electricity, which cannot meet people's high requirements for fabrics. Summary of the invention

BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Figure 1 The present invention is a flowchart of a method for preparing an ultra-soft, light, warm fleece fabric according to an embodiment of the present invention. DETAILED DESCRIPTION

[0028] In order to enable those skilled in the art to better understand the technical solution of the present disclosure, the present disclosure is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific embodiments described herein are only used to explain the present disclosure and are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0029] like Figure 1 As shown, in one aspect of the present disclosure, a method for preparing an ultra-soft, light, warm fleece fabric is provided S100, which specifically includes the following steps S110 to S130:

[0030] S110, forming antistatic polyester composite yarn and antistatic elastic spandex yarn.

[0031] Specifically, the basic raw materials are subjected to a siro spinning process to form polyester composite yarn and elastic spandex yarn; the polyester composite yarn and the elastic spandex yarn are then subjected to an antistatic treatment to obtain antistatic polyester composite yarn and antistatic elastic spandex yarn.

[0032] It should be noted that different basic raw materials should be used to form antistatic polyester composite yarn and antistatic elastic spandex yarn respectively through spinning processes. Among them, when forming the antistatic polyester composite yarn, the corresponding basic raw materials are polyester fiber and polyester-cotton, polyester and other single materials or multiple materials, for example, PET fiber, PTT fiber, etc., and the basic raw material of the antistatic elastic spandex yarn is polyurethane fiber, etc.

[0033] In some preferred embodiments, the antistatic polyester composite yarn adopts 75D / 144F ultrafine polyester, wherein 75D means that the thickness of a single yarn is approximately 0.72 mm, and 144F means that each yarn is composed of 144 ultrafine fibers, and the diameter of each fiber is less than 0.009 mm, ensuring the fineness and softness of the final fabric; the elastic spandex yarn adopts 20D elastic spandex, wherein 20D indicates the thickness of the spandex fiber, and finer fibers help to improve the softness and fluffiness of the pile layer.

[0034] It should be understood that the siro spinning process includes the steps of preparing basic raw materials, combing, refining, segging, twisting and the like to form yarn. In the present embodiment, a modifying device and a drying device are added to the above process to perform antistatic treatment on the polyester composite yarn and the elastic spandex yarn in the spinning process. The modifying device mainly includes structures such as a pulley, a sponge layer and a spray hole. In this way, the sponge layer is pre-soaked in the antistatic agent SN (octadecyl dimethyl hydroxyethyl quaternary ammonium nitrate) for 24 hours, and then the sponge is installed in the pulley groove. In this way, the yarn passes through the pulley groove and is fully contacted and squeezed with the sponge, so that the sponge layer can surround the yarn to a certain extent. At the same time, six spray hole devices can be installed above the sponge layer to continuously spray the antistatic agent SN on the sponge layer to improve the wetting effect on the yarn.

[0035] It should be understood that, at present, most of the antistatic layers are stacked in the fabric. This method has a general antistatic effect and will increase the thickness of the fabric, which cannot meet the demand for thinness. Secondly, some fabrics are treated with antistatic additives to form an antistatic layer on the surface of the fabric. This method is relatively convenient to operate, but after washing, the antistatic function of the fabric tends to gradually disappear. In view of this, in this embodiment, a new modification device is added between the yarn and the roller, and antistatic treatment is performed in the yarn production stage. The antistatic agent SN is fully wetted by the modification device to give the yarn an antistatic function. This method is low in cost, high in efficiency, and does not affect the subsequent finishing of the fabric. Moreover, the antistatic property of the fabric formed by the weaving of this yarn is not easy to disappear, and the stability of the antistatic effect is much higher than the treatment method of the fabric treated with antistatic agents, and the antistatic function continues to exist after washing. That is to say, this embodiment forms an antistatic polyester composite yarn by wrapping an antistatic layer on the outer surface of the polyester fiber yarn, and forms an antistatic elastic spandex composite yarn by wrapping an antistatic layer on the outer surface of the antistatic polyester composite yarn, and then weaving the composite yarn to form a fabric, which not only achieves the antistatic effect, but also can reduce the thickness of the fabric and is not easy to clean.

[0036] In this embodiment, the improved spinning process can ensure uniform fiber distribution, improve the strength and elasticity of the yarn, and lay a good foundation for the subsequent raising process. At the same time, based on the natural antibacterial properties of the fiber, the special blending process can achieve the natural antibacterial properties of the fabric, reaching the 3A antibacterial standard, effectively inhibiting the growth of bacteria and viruses, and having strong inhibitory properties against common bacteria such as Staphylococcus aureus, Escherichia coli and Candida albicans; while maintaining the softness and breathability of the fabric.

[0037] S120, weaving the antistatic polyester composite yarn and the antistatic elastic spandex yarn to form a main body layer, and weaving the antistatic elastic spandex yarn to form a pile layer, wherein the pile layer is located at the upper and lower sides of the main body layer, to obtain a double-sided pile base fabric.

[0038] Specifically, a 34-inch 28-level double-sided circular knitting machine is used to weave the yarn through a specific triangular arrangement to form a double-sided fabric. The middle layer of the double-sided fabric is the main layer, and the upper and lower sides of the middle layer are pile layers. The parameters of the triangular arrangement are shown in Table 1.

[0039] Table 1 Triangular arrangement parameters

[0040]

[0041] It should be noted that this embodiment does not specifically limit the ratio of antistatic polyester composite yarn and antistatic elastic spandex yarn in the main layer, and can be appropriately adjusted according to actual needs, for example, 80-90% antistatic polyester composite yarn, 10-20% antistatic elastic spandex yarn, etc.

[0042] In this embodiment, triangular arrangement knitting is adopted to form triangular arrangement weaving, in which the yarns are interwoven with each other in the shape of a triangle. This arrangement allows the fabric to form a certain spatial structure during the interweaving process, thereby generating pores. These pores constitute the microporous structure of the fabric, and the size of the microporous structure is 20-80μm, for example, preferably 20μm, 30μm, 40μm, 50μm, 60μm, 70μm, 80μm, etc.

[0043] This embodiment uses such ultra-fine fiber interweaving to make the fabric have a unique microporous structure, which not only retains the air layer to lock in body temperature and achieve efficient warmth retention, but also greatly reduces the weight of the material, making the home clothes have an unprecedented lightness while keeping warm. In addition, the microporous structure can also retain a large amount of static air that cannot be circulated, thereby achieving the effect of heat preservation without loss and high warmth retention, so that the warmth retention efficiency of the finished fabric is improved, which helps to reduce the thickness of the fabric, making it light, soft, and burden-free.

[0044] S130, the double-sided fleece base fabric is sequentially subjected to open-width washing, pre-setting, first double-sided napping, high-temperature setting, dyeing, drying, second double-sided napping, double-sided combing and shearing, and re-setting treatment to obtain an ultra-soft, light, warm fleece fabric.

[0045] Specifically, the double-faced fleece base fabric is washed in open width, and the open width washing is carried out according to the normal water washing in and out of the rolling groove at 25-35m / min (for example, 30m / min) until the slurry attached to the fabric is completely washed away, so as to facilitate the subsequent dyeing and napping treatment.

[0046] Furthermore, the temperature of the pre-setting treatment is 130°C-160°C, for example, 130°C, 140°C, 150°C, 160°C, etc., to preheat the woven base fabric to improve the plasticity of the fiber for subsequent sanding operations.

[0047] Furthermore, the first double-sided napping treatment includes the use of six napping machines arranged in sequence to perform double-sided napping treatment on the double-sided velvet base fabric. Each napping machine can perform delicate napping operations on different parts of the base fabric to ensure uniform napping effects and initially form a velvet surface, laying the foundation for further refinement and uniform distribution of the velvet. In this way, through these six napping machines with special parameters, the six napping machines process synchronously, and each machine performs fine processing on a specific dimension of the velvet, such as density, length or direction, so as to achieve the ultimate uniformity and fineness of the velvet.

[0048] It should be noted that the present embodiment does not specifically limit the parameters of the first double-sided roughening treatment. For example, a smooth roughening method is adopted with a vehicle speed of 22-25 m / min. Within this speed range, the uniformity and consistency of the fluff are further improved.

[0049] Furthermore, in the high-temperature setting treatment, the setting temperature is 150-170°C (for example, 160°C), the vehicle speed is 15-30m / min, and then a cooling treatment is performed to obtain a base cloth with a certain shape and texture, and the shape of the fluff after napping is fixed to ensure the stability of the fluff in subsequent treatments, which is not easy to deform and wrinkle, and at the same time can increase the service life of the fabric.

[0050] Furthermore, in the dyeing process, it is necessary to go through pre-treatment processes such as soaking, enzymatic treatment, and reduction cleaning to remove impurities on the base fabric, etc. After that, the dye is added to the dyeing tank, and the base fabric is soaked in the dye under certain time and temperature conditions to maintain the stability of the dye concentration, temperature and dyeing time in the dyeing tank to ensure a good dyeing effect. After that, the post-treatment steps such as washing, bleaching and shaping are carried out to wash and remove the remaining dye and impurities on the base fabric, adjust to the color and brightness required by the fabric, ensure that the color is evenly penetrated into the fluff of the base fabric, and improve the color vividness and washability.

[0051] It should be noted that for different types of fabrics, such as polyester, there are different dyeing processes, depending on whether different dyes are used to dye different fibers. For example, polyester fibers are usually dyed by hot melt dyeing or high temperature and high pressure dyeing.

[0052] Furthermore, the base fabric is dried at a temperature of 120-140° C. (eg, 130° C.) for 30-50 min (eg, 30 min, 40 min, 50 min, etc.).

[0053] Furthermore, in the second double-sided napping treatment of the base fabric, six napping machines arranged in sequence are also used to perform the second double-sided napping treatment on the base fabric. Similarly, through these six napping machines with specially designed parameters, the six napping machines process synchronously, and each machine performs fine processing on a specific dimension of the fluff, such as density, length or direction, so as to achieve the ultimate uniformity and fineness of the fluff, so that the fabric has super softness and good durability of the fluff shape. In addition, this treatment method is more efficient and does not require repeated napping treatment.

[0054] Similarly, in the second double-sided napping process, the napping method is adopted, and the speed is 22-25m / min. During the production process, this stable speed can ensure that the napping quality of each batch of double-sided velvet base fabrics can be maintained at a high level, further improving the uniformity and consistency of the nap, which is beneficial to product quality control.

[0055] In this embodiment, the two napping treatments are both performed by six napping machines in a synchronous manner. Compared with the repeated treatment by a single napping machine, the six napping machines are used for synchronous treatment. Each napping machine can simultaneously carry out napping work on the double-sided velvet base fabric from different angles and according to the set parameters. Different napping machines cooperate with each other and can perform napping operations on the base fabric in all directions, so that the intensity and frequency of napping are more evenly distributed on the entire fabric surface. The napping layer of the resulting fabric has more uniform and delicate hairiness, the fabric surface is fluffier, and the appearance is not easily changed after washing.

[0056] Furthermore, in the double-sided combing and shearing of the base fabric, the fibers on the surface of the fabric are picked up by dense needles or thorns to form a layer of fluff, which improves the warmth retention of the fabric and makes it soft. After that, the sanded fabric is precisely sheared with a high-precision shearing machine to control the length of the fluff between 0.6-1.0mm, so as to achieve a fine, uniform and non-shedding suede effect.

[0057] Furthermore, during the re-setting treatment of the base fabric, the setting temperature is 150-160°C, which consolidates all processing results and ensures that the fabric size is stable and the pile shape is durable.

[0058] In this embodiment, by optimizing the napping process, not only the uniformity and fineness of the double-sided pile fabric are greatly improved, but also the production efficiency and the quality of the finished product are effectively improved. The produced fabric will be softer, skin-friendly, fuller in color, fuller in suede and durable, meeting the demand of the high-end market for high-quality double-sided pile materials and leading a new round of technological innovation in the pile fabric industry.

[0059] Another aspect of the present disclosure provides an ultra-soft, lightweight, warm fleece fabric, which is prepared by the preparation method given above. Please refer to the above description for the specific process, which will not be repeated here.

[0060] Specifically, the ultra-soft, lightweight, warm fleece fabric of this embodiment includes: a main body layer, and fleece layers located at the upper and lower ends of the main body layer; wherein the main body layer is woven from antistatic polyester composite yarn and antistatic elastic spandex yarn; the fleece layer is woven from antistatic polyester composite yarn.

[0061] In some preferred embodiments, the main body layer includes 80-90% of antistatic polyester composite yarn and 10-20% of antistatic elastic spandex yarn.

[0062] In other preferred embodiments, the antistatic polyester composite yarn uses 75D / 144F ultrafine polyester, and the antistatic polyester composite yarn uses 20D elastic spandex. That is to say, the main layer is formed of 75D / 144F ultrafine polyester and 20D elastic spandex as the basic raw materials, and the fleece layer is formed of 20D elastic spandex as the basic raw material. The fabric formed by this ultrafine fiber feels fluffier and has better warmth retention after napping treatment, and at the same time helps to reduce the thickness of the fabric, that is, good warmth retention can be obtained under the premise of lighter and thinner fabrics without increasing the thickness of the fabric.

[0063] In other preferred embodiments, the thickness of the fleece layer is 0.4-1.0 mm, for example, 0.4 mm, 0.6 mm, 0.8 mm, 1.0 mm, etc. At the same time, the gaps between the fleece in the fleece layer are 0.2-0.5 mm, which can accommodate an appropriate amount of still air. Still air has a low thermal conductivity and can effectively hinder heat transfer and reduce heat loss from the human body. At the same time, appropriate gaps are also conducive to air circulation, so that moisture on the skin surface can be discharged in time, keeping the skin dry and comfortable, and having good air permeability.

[0064] The preparation method of the ultra-soft, light, warm fleece fabric will be further described below in conjunction with specific examples:
