Description

Technical Field

[0001] This invention relates to the field of textile fabric technology, specifically to a wool-Tencel-nylon blended fabric and its processing method, and a double-sided fleece fabric. Background Technology

[0002] Wool fibers are characterized by good elasticity, full hand feel, good moisture absorption, good warmth retention, soft luster, and shrinkage properties. They are commonly used to process clothing fabrics. However, coarse wool products with a loose structure made from pure wool are prone to shrinkage and pilling during washing and wearing.

[0003] Therefore, when utilizing wool fibers, blending is usually employed. For example, CN120291262A discloses a moisture-wicking and heat-generating high-insulation fleece fabric and its production process, relating to the field of clothing fabric technology. This moisture-wicking and heat-generating high-insulation fleece fabric and its production process utilize blended yarns composed of various functional fibers by weight percentage, including: 25% wool, 30% self-heating acrylic fiber, 25% lyocell fiber, and 20% nylon. Through the composition design of the fixed-spun yarn and the scientific proportioning, the advantages of each fiber are fully utilized, overcoming the shortcomings of single fibers.

[0004] However, when wool / Tencel blended with nylon is used for fabric production, the resulting fabric will have a large fluctuation in vertical shrinkage after washing, and the horizontal shrinkage will be mostly the opposite (generally between 5-8.9%). The slope after washing is also particularly large, which leads to garment deformation and unstable dimensions, especially after washing. Summary of the Invention

[0005] In view of the problems existing in the prior art, the purpose of the present invention is to provide a processing method for wool-Tencel-nylon blended fabric to solve the defects of large shrinkage and slope after washing in wool-Tencel-nylon blended fabric.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0008] 35-37% wool, 53-55% Tencel, and the remainder is nylon.

[0009] The wool-Tencel-nylon blended fabric provided by this invention, by designing the composition of each fiber content in the wool-Tencel-nylon blended fabric, can significantly reduce the shrinkage rate and slope after washing, so that the fabric has a certain stretch, can be machine washed, and is soft and has a wool-like feel.

[0010] As a preferred technical solution of the present invention, the wool, Tencel and nylon blended fabric is made of tightly spun wool-Tencel yarn.

[0011] Preferably, the fineness of the wool Tencel compact yarn is 50N / 1-60N / 1.

[0012] As a preferred embodiment of the present invention, the fineness of the nylon is 35-45D.

[0013] Preferably, the nylon yarn has a single filament count of 33-35F.

[0014] In a second aspect, the present invention provides a method for processing a wool-Tencel-nylon blended fabric as described in the first aspect, the method comprising:

[0015] The wool-Tencel blended yarn and nylon yarn are used for weaving, and then rolled through the spinning and setting processes to obtain the wool-Tencel nylon blended fabric.

[0016] As a preferred technical solution of the present invention, the wool-Tencel blended yarn is obtained by tightly spinning wool and Tencel.

[0017] Preferably, the yarn arrangement in the weaving process includes: the wool-Tencel blended yarn has one Z-twist and the nylon yarn has one S-twist.

[0018] Preferably, the diameter of the control coil in the weaving process is 1.1-1.3 mm.

[0019] Preferably, the width of the roll during the shaping process is 180-182cm.

[0020] As a preferred technical solution of the present invention, the forming temperature of the forming roll is 140-160℃.

[0021] Preferably, the air volume on both sides of the fabric during the setting process is 98-100% of the full-speed air volume of the setting machine and 65-75% of the full-speed air volume of the setting machine, respectively.

[0022] As a preferred embodiment of the present invention, the main overfeed ratio of the forming roll is 20-22%.

[0023] As a preferred technical solution of the present invention, the rolling speed during the shaping process is 14-16 m / min.

[0024] Preferably, the rolling mill pressure during the shaping process is 30-50N.

[0025] As a preferred technical solution of the present invention, the fabric is impregnated with resin during the shaping and rolling process.

[0026] Thirdly, the present invention provides a double-sided fleece fabric, which is obtained by napping a wool-Tencel-nylon blended fabric as described in the first aspect.

[0027] Compared with existing technical solutions, the present invention has the following beneficial effects:

[0028] The processing method provided by this invention optimizes the raw materials, weaving, and finishing processes, ultimately controlling the shrinkage rate of this type of fabric after washing to within 6%, preferably within 2.3%, and the slope to within 5%, preferably within 2.4%. This ensures that the performance of this type of fabric meets the development requirements, possesses a certain degree of stretch, is machine washable, soft, has a fuzzy feel, and can be used to prepare double-sided fleece / fleece fabrics.

The scope of protection of the present invention is determined by the claims. Detailed Implementation

[0030] To better illustrate the present invention and facilitate understanding of its technical solutions, typical but non-limiting embodiments of the present invention are as follows:

[0031] Currently, wool fibers are characterized by good elasticity, a full hand feel, good moisture absorption, good warmth retention, soft luster, and felting properties, making them commonly used in clothing fabrics. However, coarse-spun products with a loose structure made from pure wool are prone to shrinkage and pilling during washing and use. Therefore, when utilizing wool fibers, blending is usually employed. However, when using wool / Tencel blended with nylon for fabric production, the resulting fabric exhibits significant fluctuations in vertical shrinkage after washing, with transverse shrinkage generally being the opposite (typically between 5-8.9%), and a particularly large slope after washing. This leads to garment deformation and dimensional instability, especially noticeable after washing. Based on this, this invention optimizes the processing method to achieve efficient processing of wool / Tencel blended nylon fabrics, thereby reducing the shrinkage and slope of the fabric after washing, as detailed below:

[0124] After washing, the slope and shrinkage (including vertical shrinkage and horizontal shrinkage) of the fabrics obtained in the above embodiments and comparative examples were tested.

[0126]

[0127] As shown in Table 1, the wool-Tencel-nylon blended fabric provided by this invention, by designing the composition of each fiber content in the wool-Tencel-nylon blended fabric, can significantly reduce the shrinkage and slope after washing, making the fabric have a certain stretch, machine washable, soft, and fuzzy. This is because the swelling characteristics of Tencel fibers are not suitable for dry setting and require water setting to meet the shrinkage requirements. Resin is added to the setting liquid to further adhere the fibers in the fabric to each other, improving the shrinkage and shedding; and an overly loose structure will also affect the shrinkage and slope.
