Description

Technical Field

[0001] The invention relates to the technical field of fabric preparation, and in particular to a spinning method for improving the washability of a fabric and a fabric preparation method. Background Art

[0002] The spinning method is a process of forming strips of fibers such as cotton, linen, silk, wool and chemical fibers and then pulling them into yarn. The spinning process is usually divided into two stages: strip forming and yarn forming. Sliver forming is to pre-treat the fiber raw materials first, and then loosen the raw materials into single strips of a certain length. Chemical fibers are longer and need to be cut or pulled into fiber strips. The yarn forming method is to twist the fiber strips into yarn.

[0003] In the domestic and international workwear rental industry, the basic requirements for clothing fabrics are high washability, durability, and repeated washing and use. With the changes in the global economic situation, many rental companies will choose fabrics that can be washed more frequently to make work clothes in order to reduce costs. Therefore, higher requirements are placed on the performance of fabrics that can withstand repeated washing. In the international and domestic markets, fabrics with stronger washability have obvious competitive advantages.

[0004] Fabrics produced using current textile processes often have the problems of being easily worn out after multiple washes, having fuzz on the surface, and having reduced tensile strength. Summary of the invention

[0005] Based on the fact that fabrics prepared in the current textile process usually have the problems of easy wear and tear after multiple washings, easy fuzzing of the fabric surface and reduced tensile strength, the purpose of the present invention is to provide a spinning method and a method for preparing the fabric for improving the washability of the fabric. The spinning method utilizes the action of airflow to form a multi-point cross-entangled structure of the fibers in the yarn, thereby enhancing the friction between the fibers and improving the strength and elasticity of the yarn. At the same time, the yarn formed by the spinning method has an open structure with more gaps and channels. These gaps provide more paths for dyes to enter the interior of the fiber, so that the dyeing effect of the fabric is better.

[0006] The present invention is achieved through the following technical solutions:

[0007] The present application provides a spinning method for improving the washability of a fabric, comprising the following steps:

[0008] Pre-treat the spinning fiber raw materials to remove impurities in the raw materials; the spinning fiber raw materials can be cotton, linen, wool, polyester and other fibers. Pre-treatment includes washing, drying and combing the raw materials to ensure the quality and purity of the raw materials, remove impurities in the raw materials, make the fibers more uniform, and improve the efficiency and quality of subsequent spinning.

[0009] The pretreated fibers are drawn and combined into fiber bundles to improve the parallelism and compactness of the fibers; the fiber bundles are drawn by roller drafting devices to make the fiber bundles thinner and reach the required linear density;

[0010] The spiral fiber guide channel enters the spinning nozzle, and inside the spinning nozzle, air is used to make the fiber bundle move along the spiral channel and be subjected to the action of centrifugal force to twist the fiber bundle; the fiber bundle is gradually condensed and twisted into the newly formed yarn under the action of a specific airflow to become the yarn core.

[0011] Furthermore, the yarn formed after spinning is output from a yarn channel inside the spindle, and the yarn defects of the formed yarn are removed by an electronic yarn clearer.

[0012] After the yarn defects are removed, the yarn is collected and wound onto bobbins for subsequent processing and use. If the collected yarn contains impurities or is uneven, subsequent steps such as removing impurities, stretching, finishing and twisting are required to improve the quality and pass rate of the yarn.

[0013] In a second aspect, the present application provides a method for preparing a fabric, the preparation method comprising sequentially performing spinning, weaving, pretreatment, dyeing, and finishing; the spinning process adopts the above-mentioned spinning method.

[0014] Furthermore, the weaving process comprises the following steps:

[0015] Arrange the raw yarn on the reed board according to certain order, direction, tension and other requirements, and make it into a warp beam or warp cylinder suitable for weaving through finishing, sizing, drying and other treatments. The main purpose of sizing is to improve the strength and wear resistance of the yarn, eliminate yarn defects and impurities on the yarn, so as to improve the weaving performance of the warp yarn;

[0016] Install the warp beam or warp cylinder on the loom, and through the steps of warp drawing, reeding, heddle drawing, shuttle drawing, etc., the warp yarn is firmly fixed on various parts of the loom to prepare for weaving;

[0017] Install the weft shaft or weft cylinder on the weft delivery device of the loom, and make it deliver the weft yarn normally through adjustment and inspection.

[0018] Under the control of the loom, the warp yarn and weft yarn are interwoven into fabric through actions such as opening, sending the weft, beating the weft, and pulling.

[0019] After the above operations, the woven fabric is taken off the loom and inspected, trimmed, and rolled up to make it a finished or semi-finished product that meets the requirements. The fabric off the loom is further finished, such as trimming, cutting, ironing, etc., to improve the appearance quality and feel of the fabric.

[0020] Furthermore, the pre-treatment process is as follows: singeing, squeezing, dipping and squeezing the grey cloth in a scouring liquid (squeezing rate is 85%), steaming at 102°C for 50 minutes, first washing, squeezing, mercerizing, second washing, squeezing and drying.

[0021] Furthermore, during the first water washing, the vehicle speed was 40 m / min, and the temperatures of the washing tank were 75°C, 85°C, 90°C, and 60°C, respectively; during the second water washing, the temperatures of the washing tank were 80°C, 90°C, 85°C, 80°C, and 75°C, respectively.

[0022] Furthermore, the dyeing process comprises the following steps:

[0023] Immerse the prepared fabric in the dye solution, allowing the dye solution to evenly penetrate into the fabric;

[0024] The padding fabric is dried to remove excess water and uncured dye from the fabric.

[0025] The dye solution includes dye, penetrant and anti-migration agent.

[0026] Furthermore, the dried fabric is baked to solidify the dye and the adhesive.

[0027] Baking after drying can improve color fastness and color stability.

[0028] Furthermore, the post-finishing process comprises the following steps:

[0029] Immerse the prepared fabric in the working liquid, and use equipment such as a padder to make the working liquid evenly penetrate into the fabric to ensure the functional effect;

[0030] The impregnated fabric is dried to remove excess moisture and uncured additives on the fabric; the drying methods include infrared pre-drying, drum drying, etc. Among them, after drying, baking treatment is carried out according to the needs of the additives to further solidify the additives and improve the additive effect.

[0031] Pre-shrunk the fabric.

[0032] Among them, it is necessary to set an appropriate pre-shrinkage temperature according to the material and process requirements of the fabric. For all-polyester high-twist fabrics, the pre-shrinkage temperature is usually higher, reaching about 130°C, to ensure that the fabric is fully pre-shrunk.

[0033] Furthermore, the moistening and heating treatments during the pre-shrinking process are used to reduce the shrinkage of the fabric and improve the softness of the fabric feel.

[0034] During the preshrinking process, auxiliary agents for removing impurities from the fabric may also be added, and the auxiliary agents include scouring agents.

[0035] Compared with the prior art, the present invention has the following advantages and beneficial effects:

[0036] (1) The spinning method of the present invention utilizes the effect of airflow to form a plurality of cross-entangled structures in the yarn, which increases the friction between the fibers and improves the strength and elasticity of the yarn. There are more gaps and channels in the open structure formed on the yarn, which provide more paths for the dye to enter the interior of the fiber, so that the dye and the fiber molecules come into more sufficient contact, thereby improving the uniformity and depth of dyeing, and at the same time making the dye more firmly fixed inside the fiber, and not easily falling off due to friction or chemical action during washing. Even after multiple washings, the color is not easily washed off, thereby improving the color's water-resistant performance;

[0037] (2) The spinning method of the present invention can also enhance the mechanical bonding force of the fibers, so that the fabric has pilling resistance. The cross-entanglement of fibers is not only conducive to the penetration of dyes, but also increases the mechanical bonding force between fibers. This bonding force prevents the fibers from being easily separated when the yarn is subjected to external forces (such as friction during washing). The integrity of the yarn is also maintained. Since the bonding force between the fibers is enhanced, the yarn can better maintain its integrity during the washing process, reducing pilling and further improving the washability. The prepared fabric can withstand repeated washings up to 50 times, the color change value reaches level 4, and the tensile strength loss is reduced;

[0038] (3) The fabric preparation method of the present invention, combined with a specific spinning method, makes it easier for the dye to penetrate into the fiber during the dyeing stage of the fabric. At the same time, adding a cosolvent to the dye can change the properties of the fiber surface, making it more hydrophilic, thereby helping the dye to penetrate better; the penetrant added to the dye can reduce the surface tension of the dye solution, making it easier for the dye to enter the fiber and increase the ability of the dye to combine with the fiber; the cross-linking agent added to the dye can not only fix the dye on the fiber, but also form a network structure between the fibers. This network structure increases the overall strength and stability of the fiber, reduces the shedding and wear of the fiber during the washing process, and greatly improves the fastness and permeability of the dye, thereby increasing the wash resistance of the fabric.

[0099] The properties of the fabrics prepared by the methods of Example 2 and Comparative Example 1 were tested, and the test items included tensile strength (strip method), pilling (grade) 2000 revolutions, and color change after 50 industrial washings.

[0105] Table 3

[0106]

[0107] From the above test results, it can be seen that the fabric prepared by the spinning method of the present invention has more excellent washability, wear resistance and color fastness than the traditional full-ring spinning process, which confirms that the spinning method in the present invention uses the effect of airflow to form a plurality of cross-tangled structures in the yarn. This structure increases the friction between fibers and improves the strength and elasticity of the yarn. There are more gaps and channels in the open structure formed on the yarn, and these gaps provide more paths for the dye to enter the inside of the fiber, so that the dye and the fiber molecules are in more sufficient contact, thereby improving the uniformity and depth of dyeing, and at the same time making the dye more firmly fixed inside the fiber, not easy to fall off due to friction or chemical action during washing, even after multiple washings, the color is not easy to be washed off, and the washability of the color is improved, which can meet the needs of modern textile industry for high-quality textiles. The spinning method of the present invention can also enhance the mechanical binding force of the fiber, so that the fabric has pilling resistance, and the fiber cross entanglement is not only conducive to the penetration of the dye, but also increases the mechanical binding force between the fibers, and this binding force makes the yarn difficult to detach when subjected to external forces (such as friction during washing). The integrity of the yarn is also maintained. Due to the enhanced bonding force between fibers, the yarn can better maintain its integrity during the washing process, reducing pilling and further improving the wash resistance. The prepared fabric can withstand repeated washings up to 50 times, the color change value reaches level 4, and the tensile strength loss is reduced.

[0108] In addition, the fabric prepared by the spinning method of the present invention allows the dye to penetrate into the fiber more easily during the dyeing stage. At the same time, adding a cosolvent to the dye can change the properties of the fiber surface, making it more hydrophilic, thereby helping the dye to penetrate better; the penetrant added to the dye can reduce the surface tension of the dye solution, allowing the dye to enter the fiber more easily and increase the ability of the dye to combine with the fiber; the cross-linking agent added to the dye can not only fix the dye on the fiber, but also form a network structure between the fibers. This network structure increases the overall strength and stability of the fiber, reduces the shedding and wear of the fiber during the washing process, greatly improves the fastness and dye penetration of the dye, and thus increases the wash resistance of the fabric.
