Description

Technical Field

[0001] The invention relates to the field of home textiles, in particular to fabrics. Background Art

[0002] With the continuous improvement of the country's urbanization, urban life has become the trend of the times. In recent years, the rapid pace of urban life and the rise of the quality life trend have caused a significant change in consumers' requirements for home products. Comfort, technology and naturalness have become indispensable elements of home products. Therefore, in addition to ensuring the basic properties of textiles, how to meet the new needs of consumers has become the focus of research.

[0003] There are many ways to develop wrinkled fabrics. At present, home furnishing products mostly use dyeing and finishing processes, strengthen water washing and sand washing to achieve the effect of natural wrinkles. At the same time, at the weaving level, strong twist yarn or positive and negative twist yarn is used to arrange the fabric organization reasonably to achieve the natural style of wrinkles. The problem with the dyeing and finishing process is that the three-dimensional sense of natural wrinkles is not strong, and there is often only a sense of old, without obvious three-dimensional wrinkle relaxation. At present, weaving is often based on multi-layer fabrics, and all of them use enhanced water washing as the core technology to achieve wrinkling. It is hoped that the industrial water washing and ring drying process will bring about the contraction of the fiber, thereby bringing about the feeling of wrinkles. The wrinkling effect of this process is too abrupt, the uniformity is not enough, and the fabric has a sense of old, the texture is not high, and it cannot achieve the texture required for high-end fabrics. When applied to the home furnishing field, the scope of application is often greatly limited.

[0004] Patent publication number CN 114347583 A discloses a multi-layer cotton fabric washing and wrinkling process and fabric, the key core technical points of which are: 1. Applicable to multi-layer cotton fabrics. 2. Use of positive and negative twist yarns. 3. Alkaline oxygen one-bath water washing and wrinkling and tumble drying. From the results, this prior art achieves the wrinkling effect, but the wrinkles are too obvious, the three-dimensional sense is relatively abrupt, and the natural style is lost. At the same time, because it is a multi-layer fabric, the scope of application is greatly affected. Summary of the invention

[0005] The purpose of the present invention is to provide a method for processing fabrics with natural wrinkle textures to solve the above technical problems.

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below with reference to specific illustrations.

[0023] A method for processing a fabric with a natural wrinkle texture comprises the following steps:

[0024] Step 1: Yarn selection: There are three types of yarns, namely, S yarn with "S" twist, Z yarn with "Z" twist, and conventional yarn; preferably, the S yarn, Z yarn, and conventional yarn are all pure cotton yarn or cellulose yarn. The twist of S yarn and Z yarn is 1.35 times that of conventional yarn;

[0025] Step 2: Grey fabric weaving: The warping arrangement order of radial yarn is S yarn and Z yarn alternately, and the weft direction is conventional yarn;

[0026] The grey fabric structure is a plain weave with a warp density of 130-150 / inch and a weft density of 120-135 / inch; or, the grey fabric structure is a satin weave with a warp density of 190-210 / inch and a weft density of 85-105 / inch; or, the grey fabric structure is a twill weave with a warp density of 130-145 / inch and a weft density of 60-80 / inch;

[0027] Step 3: Post-processing: After dyeing, desizing, bleaching, dyeing and heat setting, the grey cloth will have a natural wrinkle texture.

[0028] Example

[0029] Step 1: Yarn selection: There are three types of yarns, namely S yarn, Z yarn and conventional yarn. The specification is 60S. The twist of S yarn and Z yarn is 1.35 times that of conventional yarn. Preferably, the provided yarn needs to be treated with a yarn singeing process, which mainly removes the hairiness of the yarn. The temperature of the burner is 1000±50℃, and the speed is 890m / min. Preferably, the provided yarn needs to be sized with a full starch slurry.

[0030] Step 2: Grey fabric weaving: The fabric is woven using an air jet loom, and the radial yarn warping arrangement order is designed in a "S" twist and "Z" twist yarn alternately (the spinning process of S twist and Z twist is basically the same, mainly the twisting direction is different when spinning), so that there are internal stresses in different directions inside the gauze, and the stress and strain of the yarn are continuously, slowly and evenly released during the entire processing process. The weft direction is conventional yarn, and the specification is 60S. The grey fabric structure is a plain weave with a warp density of 130-150 / inch and a weft density of 120-135 / inch; or, the grey fabric structure is a satin weave with a warp density of 190-210 / inch and a weft density of 85-105 / inch; or, the grey fabric structure is a twill weave with a warp density of 130-145 / inch and a weft density of 60-80 / inch.

[0031] Step 3: Post-treatment: After the fabric has gone through the dyeing and finishing process, the strong twisted yarn will release the internal stress, and this effect will reduce the strength of the fabric. Example 1 The warp density of the fabric is designed to be 150, and the weft density is designed to be 120.

[0032] The provided grey fabric needs to be singed to remove the surface hairiness. The flame temperature is 800-900℃, the wind pressure is 20±2mbar, the speed is 100±5m / min, and the burner is one positive and one negative.

[0033] The desizing process of the provided grey cloth uses a biological enzyme desizing process, and the specific process is amylase 2% (owf), temperature 55°C, time 45min. After desizing, the water washing uses 1 hot water wash at 95°C, time 15min, 1 warm water wash at 45°C, time 10min, 1 cold water wash at room temperature, time 15min, and the bath ratio is 1:15.

[0034] The scouring and bleaching process of the grey cloth uses a cold pad-batch process and an alkali oxygen one-bath process, and the specific process is: 5g / L sodium hydroxide, 3.5% hydrogen peroxide, 3g / L hydrogen peroxide stabilizer, 4g / L refining agent, the liquid rate is controlled at 80%, the cold stack environment is 25°C, the humidity is 80%, and the cold stack time is 24-48h. The whiteness of the grey cloth after the scouring and bleaching process needs to be controlled at 78 (±2), and the gross effect is 12cm.

[0035] The dyeing process of the grey cloth is that the dyeing equipment is an overflow cylinder, the dyeing process is a loose active dyeing process, the dye concentration is 2%, and the colored fabric is cleaned and the pH is neutralized in the overflow cylinder.

[0036] After washing, the dyed fabric needs to be physically beaten in a wet state. During this process, steam is used to control the moisture content and temperature of the fabric, and wind speed is used to control the fabric speed. Finally, through physical beating, the gaps between the yarns are made larger to ensure the complete shrinkage of the yarns. Speed ​​10m / min, temperature 58℃±2, wind speed 65%, water volume 800L, water speed 55%, and fabric storage volume 280m.

[0037] After dyeing, the fabric is polished with cellulase to remove the fine fluff on the surface of the fabric, making the fabric smoother. At the same time, polishing can improve the friction of the surface of the fabric, reduce the tightness between the yarns of the fabric, and activate the feel of the fabric. Cellulase 1.5%, temperature 55℃, time 30min, bath ratio 1:15, pH value 4.5-6.5.

[0038] In order to ensure the flatness of the fabric after treatment, the fabric needs to be heat-set. The heat-setting process is a process of applying tension to the fabric.

[0039] Examples 1, 2, and 3 in the following table all use the yarn of the present invention and the processing method of the present invention. Comparative Example 1 uses conventional yarn, the weaving parameters of the present invention, and the post-processing method of the present invention; Comparative Example 2 uses the yarn of the present invention and the conventional processing method; Comparative Example 3 uses conventional yarn and the conventional processing method.

[0040]

[0041] The formation of the natural wrinkle texture of the present invention runs through the entire production process. It is different from the design of fabric processes such as seersucker, in which the wrinkle forming process of seersucker is carried out at a separate point in the process, such as Figure 1 In order to better reflect the naturalness of the folds, the wrinkling process is carried out throughout the entire process flow section, and each process detail is cleverly designed, ultimately presenting a natural fold texture, such as Figure 2 shown.
