Description

Technical Field

[0001] This invention relates to the field of fabric production technology, and more specifically, to a production process for lightweight, warm wool knitted fabric. Background Technology

[0002] Skiing takes place in a relatively cold environment, which places certain demands on the clothing worn by skiers. Wool sweaters are a popular choice, and these sweaters require specific conditions, such as warmth to protect against the cold, lightweight for ease of movement, and durability to prevent damage from falls. Wool is a highly absorbent fiber that can be combined with other fibers to create functional effects. Polypropylene is lightweight, resulting in thin and light garments, while nylon offers excellent toughness and abrasion resistance. Both meet the performance requirements of skiing clothing. This invention, through research on the combination of these three raw materials, has developed a wool knitted fabric that meets the performance requirements of skiing. Summary of the Invention

[0003] To overcome the above-mentioned defects of the prior art, embodiments of the present invention provide a production process for lightweight and warm wool knitted fabrics.

[0004] To achieve the above objectives, the innovative aspects of this invention are as follows: Wool knitted fabric comprises a surface layer, a middle layer, and an inner layer; the specific production process of wool knitted fabric includes the following steps:

[0005] S1. Raw material selection: wool and A-type nylon core-spun wool are selected as the knitting yarn for the outer layer of the fabric, B-type nylon is selected as the knitting yarn for the middle layer of the fabric, and polypropylene is selected as the knitting yarn for the inner layer of the fabric.

[0006] S2, Needle Arrangement: Arrange needles on a 34-inch 28G double-sided circular knitting machine. The needle arrangement sequence is as follows: the needles on the needle plate are arranged in a cycle of 1, 2, 1, 2, and the needles on the syringe are arranged in a cycle of 1, 2, 1, 2.

[0007] S3. Knitting: The knitting method for the outer layer of the fabric is as follows: the first and second stitches of the rotary needle are without needles, and the first and second stitches of the cylinder needle are in loops. The knitting method for the middle layer of the fabric is as follows: the first stitch of the rotary needle is without needles, the second stitch of the rotary needle is in loops, the first stitch of the cylinder needle is in a tucked loop, and the second stitch of the cylinder needle is without needles. The knitting method for the inner layer of the fabric is as follows: the first and second stitches of the rotary needle are in loops, and the first and second stitches of the cylinder needle are without needles.

[0008] S4. Dyeing and finishing: The dyeing and finishing process of wool knitted fabrics is carried out at 110℃.

[0009] S5, brushed: The inner layer of the fabric is brushed.

[0010] Furthermore, the aforementioned Type A nylon is 20D, and Type B nylon is 70D. In this invention, as a preferred embodiment, the dyeing and finishing process includes the following steps: bleaching, dehydration and splitting, drying, pre-stretching and setting, napping, post-stretching and setting, and nylon blanket setting.

[0011] Furthermore, during the drying process, the drying speed is 20 m / min, and the drying cycle is once.

[0012] Furthermore, in the forward stretching and setting process, the setting speed is 20 m / min and the overfeed is 30%.

[0013] Furthermore, during the napping process, the number of light napping cycles is 5, the napping speed is 17m / min, the straight needle rate is -1%, and the curved needle rate is +33%.

[0014] Furthermore, in the post-stretching and setting process, the setting speed is 20 m / min and the overfeed is 35%.

[0015] Furthermore, in the nylon blanket shaping process, the shaping speed is 25 m / min and the pre-shrinkage rate is 3%.

[0016] The technical effects and advantages of this invention are as follows: The outer layer of the fabric is made of wool and A-type nylon core-spun, which increases the abrasion resistance of the fabric surface. The inner layer of the fabric is made of polypropylene, which is lightweight and non-absorbent, giving the wool knitted fabric an overall lightweight characteristic. Combined with the water absorption properties of wool, the two complement each other, achieving the unidirectional moisture-wicking characteristic of the wool knitted fabric. The interlayer of the fabric uses B-type nylon as the connecting yarn between the polypropylene and wool / nylon. The polypropylene and nylon are woven in a staggered pattern, ensuring that when the skin sweats during exercise, the moisture is carried to the fabric surface through the conduction effect of polypropylene and B-type nylon, while also providing lightweight warmth, meeting the needs of skiing.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] like Figure 1 In one specific embodiment of the present invention, the wool knitted fabric includes a fabric outer layer 1, a fabric interlayer 2, and a fabric inner layer 3. The production process of the wool knitted fabric specifically includes the following steps:

[0020] S1. Raw material selection: wool and A-type nylon core-spun wool are selected as the weaving yarn for the outer layer 1 of the fabric, B-type nylon is selected as the weaving yarn for the middle layer 2 of the fabric, and polypropylene is selected as the weaving yarn for the inner layer 3 of the fabric.

[0021] S2, Needle Arrangement: Arrange needles on a 34-inch 28G double-sided circular knitting machine. The needle arrangement sequence is as follows: the needles on the needle plate are arranged in a cycle of 1, 2, 1, 2, and the needles on the syringe are arranged in a cycle of 1, 2, 1, 2.

[0022] S3. Knitting: The knitting method for the outer layer 1 of the fabric is as follows: the first and second stitches of the needle plate are not needles, and the first and second stitches of the needle cylinder are loops. The knitting method for the interlayer 2 of the fabric is as follows: the first stitch of the needle plate is not needles, the second stitch of the needle plate is loops, the first stitch of the needle cylinder is a tuck loop, and the second stitch of the needle cylinder is not needles. The knitting method for the inner layer 3 of the fabric is as follows: the first and second stitches of the needle plate are loops, and the first and second stitches of the needle cylinder are not needles.

[0023] S4. Dyeing and finishing: The dyeing and finishing process of wool knitted fabrics is carried out at 110℃.

[0024] S5, brushing: Brush the inner layer 3 of the fabric.

[0025] In this invention, the outer layer 1 of the fabric is made of wool and A-type nylon core-spun, which can increase the abrasion resistance of the outer layer 1. The inner layer 3 of the fabric is made of polypropylene. Polypropylene is lightweight and non-absorbent, which makes the wool knitted fabric lightweight overall. Combined with the water absorption properties of wool, the two complement each other, realizing the one-way moisture wicking characteristic of the wool knitted fabric. The interlayer 2 of the fabric is made of B-type nylon as the connecting yarn between polypropylene and wool / nylon. Polypropylene and nylon are woven in a staggered pattern to ensure that when the skin sweats during exercise, the moisture is carried to the outer layer 1 of the fabric through the conduction effect of polypropylene and B-type nylon, while also providing lightweight warmth.

[0026] In this invention, polypropylene is not heat resistant, and the dyeing and finishing process is controlled below 110°C. At the same time, in order to increase the warmth of the wool knitted fabric, the inner layer 3 of the fabric is brushed, which increases the comfort of the skin in contact with the inner layer 3 of the fabric.

[0027] In this invention, as a preferred embodiment, the aforementioned type A nylon is 20D and the type B nylon is 70D. In this invention, as a preferred embodiment, the dyeing and finishing process includes the following steps: bleaching, dehydration and splitting, drying, pre-stretching and setting, napping, post-stretching and setting, and nylon blanket setting.

[0028] In this invention, as a preferred embodiment, the drying speed is 20 m / min and the drying process is performed once.

[0029] In this invention, as a preferred embodiment, the setting speed in the forward stretching and setting process is 20 m / min, and the overfeed is 30%.

[0030] In this invention, as a preferred embodiment, during the napping process, the number of light napping cycles is 5, the napping speed is 17m / min, the straight needle rate is -1%, and the curved needle rate is +33%.

[0031] In this invention, as a preferred embodiment, the setting speed is 20 m / min and the overfeed is 35% during the post-stretching and setting process.

[0032] In this invention, as a preferred embodiment, the shaping speed in the nylon blanket shaping process is 25 m / min, and the pre-shrinkage rate is 3%.

[0033] In this invention, due to the poor dyeing performance of polypropylene, the dyeing and finishing process of wool knitted fabrics is optimized at a temperature of 110°C. By adjusting various parameters during the dyeing process, the dyeing of wool knitted fabrics is ensured.

[0034] Finally, the following points should be noted: First, in the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection", and "linkage" should be interpreted broadly, and can be mechanical or electrical connections, or internal connections between two components, or direct connections.
