Description

Technical Field

[0001] The present invention provides a production process for woolen silver silk fabric, belonging to the technical field of textile fabrics. Background Art

[0002] In the textile industry, traditional woolen fabrics, although having a certain degree of warmth retention, are relatively single in appearance and have limitations in functionality. With the development of fashion trends, consumers' requirements for the aesthetics and uniqueness of clothing fabrics are increasing day by day. Incorporating silver silk into woolen fabrics has become a new idea to enhance their fashion sense and gloss. However, the strength of silver silk is poor, and it is extremely easy to break when directly used in rapier loom weaving. This technical problem has restricted the development of woolen silver silk fabrics and urgently requires an innovative production process to overcome.

[0003] Therefore, in view of this, the existing structure is studied and improved, and a production process for woolen silver silk fabric is proposed to solve the above-mentioned problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is a production process for woolen silver silk fabric, which solves the problem of easy breakage during weaving through silver silk doubling treatment and is stably applied to woolen fabrics to enhance fashion and gloss; through a specific process, the fabric has the characteristics of softness, warmth retention and stable structure, meeting the high-quality requirements.

[0005] In order to solve the above problems, the technical solution proposed by the present invention is: a production process for woolen silver silk fabric, comprising the following steps:

[0006] S1. Raw material selection: Select natural protein fibers such as cashmere, wool, yak hair and camel hair as the basic raw materials, where the proportion of cashmere is not less than 10% to ensure the skin-friendly touch of the fabric, wool provides the skeleton support, and yak hair and camel hair can be added according to requirements. The raw materials are detected by infrared spectroscopy to confirm the fiber purity, and ultrafine fibers with a diameter ≤ 21μm are screened through microscopic imaging technology to ensure the fineness of the finished product from the source;

[0007] S2. Raw material pretreatment: Wash, comb and dry the selected raw materials to remove impurities, ensure the purity and softness of the raw materials, and prepare for subsequent processing;

[0008] S3. Dyeing and spinning: Adopt the process of dyeing first and then spinning. For fabrics of a specific weight, spin 16 Nm / 1 single yarn, and control the twist to 520 Z twist. Complete the spinning through the worsted process to make the yarn have appropriate strength and twist;

[0009] S4. Silver wire parallel winding treatment: Wind the spun yarn and silver wire together to solve the problem that the silver wire is prone to breakage when directly fed into the rapier loom due to its poor strength, and ensure that the silver wire is stably present in the fabric during the weaving process. Select metallized polyester silver wire with a diameter of 0.08 - 0.15 mm (tensile strength ≥ 3.2 cN / dtex). Install a multi-stage tension controller on the parallel winding machine to compound the silver wire and wool yarn at a ratio of 1:1, and strictly control the compounding speed at 25 m / min, reducing the silver wire breakage rate from 15% in the traditional process to 1.8%.

[0010] S5. Weaving process: Adopt a 2-up 2-down right twill double-layer structure. Use fluff blended yarn for the warp yarn and silver wire composite yarn for the weft yarn. Achieve a warp density of 389 roots / 10 cm through an electronic large rapier, and cooperate with a weft density of 374 roots / 10 cm to form a high-density structure with a gram weight of 800 g / m². Maintain a constant temperature of 22 °C and a humidity of 65% in the weaving workshop. Use ceramic yarn guides to reduce the friction of the silver wire and ensure that the weaving defect rate is less than 0.3%.

[0011] S6. Post-treatment process: Use imported equipment for washing and shrinking treatment. Wash the front side to produce a suede surface, raise the nap on the back side, and then go through drying, calendering, shearing, and shaping to make the fabric reach the ideal appearance and hand feeling. Finally, conduct finished product inspection.

[0012] Furthermore, the specific parameters of the washing, carding, and drying process in step S2 are required, including the washing time, carding times, drying temperature, and time.

[0013] Furthermore, the dyes used for dyeing in step S3 are selected according to the color design requirements of the fabric, and the equipment parameters of the semi-worsted process need to be fine-tuned according to the yarn quality requirements.

[0014] Furthermore, the specific weight of the fabric in step S3 is 800 grams.

[0015] Furthermore, the silver wire accounts for 8 - 10 g / m of the fabric gram weight in step S4.

[0016] Furthermore, the raw material pretreatment in step S2 adopts a three-step purification process: First, use 45 °C soft water for circulating flushing to remove lipid impurities, then conduct 6-way bidirectional carding through a sawtooth roller carding machine to make the fiber orientation degree reach more than 92%, and finally conduct gradient drying in a closed-loop drying system with a constant humidity (55% ± 3%) to accurately control the fiber moisture regain between 12% - 14%, retaining the natural flexibility and avoiding static electricity accumulation.

[0017] Further, in step S3, the dyeing and spinning adopt the "low-temperature cationic dyeing-microcapsule color fixation" process, complete the penetration in a 60°C dye bath, and the color fastness reaches 4-5 levels. For the silver wire composite requirement, the basic yarn is designed as 16 Nm / 1 single yarn, and the precise application of 520 Z twist is monitored in real time through an electronic twist meter, and it is combined with the 60 rpm low-speed drafting of the woolen spinning equipment to form a three-dimensional yarn body structure with a bulkiness of 35%, creating an ideal carrier for the silver wire composite.

[0018] Due to the adoption of the above technical solution, the beneficial effects of the manufacturing process of the woolen silver wire fabric of the present invention are as follows:

[0019] 1. The present invention adopts a unique silver wire parallel processing, successfully solves the problem that silver wires are easily broken during the weaving process, realizes the stable application of silver wires in woolen fabrics, improves the fashion sense and gloss of the fabrics, and brings a new visual experience to consumers.

[0020] 2. Through specific raw material pretreatment, spinning, weaving and post-treatment processes, the woolen silver wire fabric of the present invention has good softness, warmth retention and structural stability. It meets the needs of consumers for high-quality fabrics, is suitable for making warm winter clothes, and can also show a fashionable appearance. Description of the Drawings

[0026] S1. Raw material selection: Natural protein fibers such as cashmere, wool, yak hair, and camel hair are selected as the basic raw materials. Among them, the proportion of cashmere is not less than 10% to ensure the skin-friendly touch of the fabric. Wool provides the framework support, and yak hair and camel hair can be added according to requirements. The raw materials are detected by infrared spectroscopy to confirm the fiber purity, and ultra-fine fibers with a diameter ≤ 21μm are screened through microscopic imaging technology to ensure the fineness of the finished product from the source;

[0027] S2. Raw material pretreatment: The selected raw materials are washed, combed, and dried to remove impurities, ensuring the purity and softness of the raw materials and preparing for subsequent processing;

[0028] S3. Dyeing and spinning: Adopt the process of dyeing first and then spinning. For fabrics of a specific weight, spin 16 Nm / 1 single yarn, and control the twist to 520 Z twist. Complete the spinning through the woolen spinning process to make the yarn have appropriate strength and twist;

[0029] S4. Silver wire parallel winding treatment: The spun yarn is parallel wound with silver wire to solve the problem that the silver wire is prone to breakage when directly used on the rapier loom due to its poor strength, ensuring the stable presence of silver wire in the fabric during the weaving process. Select metallized polyester silver wire with a diameter of 0.08 - 0.15 mm (tensile strength ≥ 3.2 cN / dtex), install a multi-stage tension controller on the parallel winding machine, make the silver wire and wool yarn composite at a ratio of 1:1, and strictly control the composite speed at 25 m / min, reducing the silver wire breakage rate from 15% in the traditional process to 1.8%;

[0030] S5. Weaving process: Adopt a 2-up 2-down right twill double-layer structure. The warp yarn uses a fluff blended yarn, and the weft yarn uses a silver wire composite yarn. Achieve a warp density configuration of 389 threads / 10 cm through an electronic large rapier loom, cooperate with a weft density of 374 threads / 10 cm to form a high-density structure with a gram weight of 800 g / m². The weaving workshop maintains a constant temperature of 22°C and a humidity of 65%. Use ceramic yarn guides to reduce the friction of silver wire and ensure that the weaving defect rate is less than 0.3%;

[0031] S6. Post-treatment process: Use imported equipment for washing and shrinking treatment, wash out the velvet surface on the front, raise the nap on the back, and then go through drying, calendering, shearing, and shaping to make the fabric reach the ideal appearance and feel. Finally, conduct finished product inspection.

[0032] In step S2, specific parameters for the washing, combing, and drying process are required, including the washing time, the number of combing times, the drying temperature, and the drying time.

[0033] In step S3, the dyes used for dyeing are selected according to the color design requirements of the fabric, and the equipment parameters of the woolen spinning process need to be fine-tuned according to the yarn quality requirements.

[0034] The fabric of a specific weight in step S3 is 800 grams.

[0035] In step S4, the silver wire accounts for 8 - 10 g / m of the fabric gram weight.

[0036] In step S2, the raw material pretreatment adopts a three-step purification process: first, rinse with 45°C soft water in a cycle to remove lipid impurities, then conduct 6-way bidirectional carding through a sawtooth roller carding machine to make the fiber orientation degree reach more than 92%, and finally conduct gradient drying in a closed-loop drying system with a constant humidity (55% ± 3%) to accurately control the fiber moisture regain between 12% - 14%, which not only retains the natural flexibility but also avoids static electricity accumulation.

[0037] In step S3, the dyeing and spinning adopt the "low-temperature cationic dyeing - microcapsule color fixation" process, complete penetration in a 60°C dye bath, and the color fastness reaches level 4 - 5. For the silver wire compounding requirement, the basic yarn is designed as 16 Nm / 1 single yarn, and the accurate application of 520 Z twist is monitored in real time through an electronic twist meter, and combined with the low-speed drafting of 60 rpm of the worsted equipment to form a three-dimensional yarn body structure with a bulkiness of 35%, creating an ideal carrier for silver wire compounding.

[0038] This process has breakthroughly solved the processing problems caused by the physical property differences between silver wire and wool fibers. The finished fabric is tested and shown that: the bending stiffness is only 3.2 cN·cm 2 / cm, the warmth retention rate is increased by 18%, the silver wire retention rate reaches 97.5%, and the color difference ΔE of washing resistance ≤ 1.2. This fabric combines the luxurious touch of cashmere, the flowing light texture of silver wire and the crisp shape of woolen cloth, and is suitable for high-end fashion, business formal wear and light luxury home furnishing fields. Verified by the market, the product premium space reaches 2.3 times that of ordinary woolen cloth, with significant economic benefits and industry demonstration value.

[0039] The above describes the present invention and its implementation manners. This description is not restrictive. Generally speaking, if those of ordinary skill in the art are inspired by it and without departing from the purpose of the present invention creation, without creative design, structures and embodiments similar to this technical solution are all within the protection scope of the present invention.
