Yarn with characters as well as preparation method and application thereof

Abstract

The invention belongs to the technical field of textile yarns, and particularly relates to a yarn with characters as well as a preparation method and application thereof, and the yarn is prepared by longitudinally cutting a paper strip printed with longitudinally arranged characters into strips through a twisting process; wherein the characters are continuously and spirally distributed in the axial direction of the yarn, so that when the yarn is axially unfolded, the characters can be completely read; moreover, when the yarn is used for weaving a fabric, the surface of the fabric presents a dot-shaped visual texture formed by the local segments of the characters. The invention not only ensures that the characters are complete and readable when the yarn is axially unfolded, but also ensures that when the yarn is used for weaving, due to random overlapping of the spiral structure and fabric interweaving points, the characters are naturally segmented into local segments and emerge on the surface of the fabric in a point-like visual texture form, so that a unique hazy aesthetic effect is formed; the decorative property and the secrecy property are realized.

Description

Technical Field

[0001] This invention belongs to the field of textile yarn technology, specifically relating to a yarn with lettering, its preparation method, and its application. Background Technology

[0002] Traditional textile yarns are primarily used to achieve the physical properties of fabrics (such as strength, elasticity, and breathability), and their function is limited to decoration and protection. However, with increasing demand for personalized and culturally meaningful textiles, the market is increasingly seeking fabrics with special visual effects and symbolic significance.

[0003] While existing technologies offer methods for displaying text or patterns on fabric surfaces through printing, embroidery, etc., these methods suffer from the following problems: 1. The text exists only on the surface of the fabric and is easily worn off due to friction and washing; 2. It cannot achieve deep embedding of text information, lacking a sense of hierarchy and mystery; 3. The production process is complex and the cost is high.

[0004] Therefore, this invention is proposed. Summary of the Invention

[0005] To address the technical problems existing in the prior art, this invention provides a yarn with lettering, its preparation method, and its application.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A type of yarn with text is made by cutting strips of paper with vertically arranged text into strips and then twisting them; wherein the text is distributed in a continuous spiral along the axis of the yarn, so that the text can be read completely when the yarn is axially unfolded; and when the yarn is used to weave a fabric, the surface of the fabric presents a dotted visual texture composed of partial fragments of the text.

[0007] The spacing between adjacent characters along the yarn axis is 0.5 mm to 3.0 mm.

[0008] The width of the paper strip is 0.7 mm to 20 mm, and the basis weight of the paper strip is 10 g / m² to 50 g / m².

[0009] The twisting process has a twist rate of 200 twists / meter to 1500 twists / meter.

[0010] The yarn with lettering is a composite yarn, which is made by combining the paper strips and textile fibers through covering, twisting or wrapping.

[0011] The textile fiber is selected from at least one of cotton, polyester, nylon, or blended yarn.

[0012] The weight ratio of the paper strip to the textile fiber is (30-50):(50-70).

[0013] A method for preparing yarn with lettering, characterized by comprising the following steps: (1) Text printing: On paper with a basis weight of 10 to 50 grams per square meter, text is printed in a vertical arrangement using digital printing technology or handwriting. (2) Longitudinal cutting: Cut the printed paper longitudinally into strips with a width of 0.7 to 10 mm, with the cutting accuracy controlled within ±0.1 mm, and ensure that the text is centered on the strip. (3) Twisting into yarn: The paper strip is twisted alone or together with textile fibers, with the twist controlled at 200-1500 twists / meter and the twisting direction being Z-twist or S-twist. During the twisting process, the yarn tension is controlled within the range of 20-30 cN, so that the text is continuously distributed in a spiral shape along the yarn axis, and the axial spacing between adjacent text is 0.5-3.0 mm. (4) Winding and shaping: The twisted yarn is wound onto a yarn bobbin to obtain the finished yarn with lettering.

[0014] The application of yarn with lettering in textiles is used to prepare decorative fabrics, commemorative clothing, or anti-counterfeiting label fabrics.

[0015] The decorative fabrics include high-end formal wear, fashionable outerwear, and home textiles; the commemorative clothing includes wedding dresses, school uniforms, group uniforms, and commemorative T-shirts; and the anti-counterfeiting fabrics include high-end brand clothing, special uniforms, and replicas of cultural relics.

[0016] The beneficial effects of this invention are as follows: This application prints text vertically on strips of paper, and then precisely cuts and twists them to a specific twist, so that the text is distributed in a continuous spiral along the yarn axis. This not only ensures that the text is fully readable when the yarn is spread out in the axis (meeting the needs of anti-counterfeiting, information recording, etc.), but more importantly, when the yarn is used for weaving, due to the random overlap of the spiral structure and the interlacing points of the fabric, the text is naturally divided into local fragments and appears on the fabric surface in the form of dotted visual texture, forming a unique hazy aesthetic effect that is both decorative and discreet. Furthermore, by limiting the spacing between adjacent characters, the width of the paper strip, the basis weight, and the twisting tension, the display density and clarity of the characters are optimized while ensuring the strength of the paper-based yarn. By compounding with textile fibers such as cotton, polyester, or nylon, the flexibility, abrasion resistance, and weavability of the yarn are significantly improved, solving the defect of pure paper yarn being brittle and prone to breakage. The preparation method uses digital printing, high-precision cutting, and tension control to ensure the stability of production and the accuracy of text positioning. Ultimately, this yarn with lettering can be widely used in high-end formal wear, commemorative clothing, and anti-counterfeiting fabrics. It not only achieves the flexible carrying of cultural symbols but also creates a novel visual language, enhancing the added value of products and opening up new paths for the functionalization and artistry of textiles. Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0018] A type of yarn with text is made by cutting strips of paper with vertically arranged text into strips and then twisting them. The text is distributed in a continuous spiral along the axis of the yarn, so that the text can be read completely when the yarn is axially unfolded. Furthermore, when the yarn is used to weave fabric, the fabric surface presents a dotted visual texture composed of partial fragments of text.

[0019] The spacing between adjacent characters along the yarn axis is 0.5 mm to 3.0 mm. The width of the paper strip is 0.7 mm to 10 mm, and the basis weight of the paper strip is 10 g / m² to 50 g / m². The twist rate of the twisting process is 200 twists / m to 1500 twists / m.

[0020] The yarn with lettering is a composite yarn, which is made by wrapping, twisting or wrapping paper strips and textile fibers. The textile fibers are selected from at least one of cotton, polyester, nylon or blended yarns (blended yarns can be Lyocell, Modal, etc.); the weight ratio of paper strips to textile fibers is (30-50):(50-70).

[0021] A method for preparing yarn with lettering includes the following steps: (1) Text printing: On paper with a basis weight of 10 to 50 grams per square meter, text is printed in a vertical arrangement using digital printing technology or handwriting. (2) Longitudinal cutting: Cut the printed paper longitudinally into strips with a width of 0.7 to 10 mm, with the cutting accuracy controlled within ±0.1 mm, and ensure that the text is centered on the strip. (3) Twisting into yarn: The paper strips are twisted individually or together with textile fibers, with the twist controlled at 200-1500 twists / meter. The twisting direction is Z-twist or S-twist. During the twisting process, the yarn tension is controlled within the range of 20-30 cN, so that the text is continuously distributed in a spiral shape along the yarn axis, and the axial spacing between adjacent text is 0.5-3.0 mm. (4) Winding and shaping: The twisted yarn is wound onto a yarn bobbin to obtain the finished yarn with lettering.

[0022] The application of text-embedded yarn in textiles is used to prepare decorative fabrics, commemorative garments, or anti-counterfeiting textiles. Decorative fabrics include high-end formal wear (using the dotted visual effect of the text-embedded yarn to create a unique fabric texture), fashionable outerwear (encoding blessings, poems, etc., into the yarn, giving the clothing cultural connotations), and home textiles (curtains, cushions, etc., creating a warm atmosphere); commemorative garments include wedding dresses (encoding the couple's names, wedding date, etc., into the yarn), school uniforms / group uniforms (embedding school mottoes, class slogans, etc.), and commemorative T-shirts (recording text information of special moments); anti-counterfeiting textiles include high-end branded clothing (encoding brand names and anti-counterfeiting codes into the yarn), special uniforms (embedding unit logos, serial numbers, etc.), and artifact reproduction (embedding relevant information when reproducing historical artifacts). Paper is the carrier of text, and clothing is the carrier of culture. This technology and application allow cultural connotations to be better integrated into clothing, enhancing its added value.

[0023] Example 1: Pure paper yarn with lettering The process flow is as follows: 1. Text printing 12g thin paper is selected as the base material; the text is printed vertically on the paper surface using digital printing technology or handwriting; the text height is adjusted according to the width of the paper strip to ensure readability.

[0024] 2. Paper strip cutting Cut the printed paper lengthwise into strips 1.5mm wide; control the cutting accuracy within ±0.1mm to ensure that the text is centered on the paper strip and the edges are neat.

[0025] 3. Twist into yarn Twisting is performed using a ring twisting machine; the twisting direction is Z-twist; the twist is 1000 twists / meter; and the twisting speed is 8000 revolutions / minute.

[0026] 4. Winding and forming The twisted yarn is wound onto the yarn bobbin. The tension is controlled at 20-30 cN, and the yarn diameter is approximately 0.3-0.5 mm.

[0028] Example 2: Paper / cotton blend yarn with lettering The process flow is as follows: 1. Text printing and paper strip cutting (same as Example 1).

[0029] 2. Fiber preparation It uses combed cotton fibers with a length of 28-30mm; the cotton fiber weight is 1.2dtex.

[0030] 3. Blended twisting The paper strips and cotton fibers are blended at a weight ratio of 40:60, with an S-twist direction and a twist of 900 twists / meter. A double-strand twisting process is also used.

[0031] 4. Post-processing Perform a softening process to improve the feel; set the heat setting temperature to 120℃ and the time to 3 minutes.

[0032] The characteristics of the resulting product are as follows: yarn breaking strength: ≥220cN / tex; retains the spiral distribution characteristics of the text, has a soft hand feel, and is suitable for close-fitting clothing; and has excellent washability.

[0033] Example 3: Paper / Polyester Blended Yarn with Lettering The process flow is as follows: 1. Text printing and paper strip cutting (same as Example 1).

[0034] 2. Fiber preparation Polyester staple fiber with a length of 38mm was selected; the basis weight of the polyester fiber was 1.5dtex.

[0035] 3. Blended twisting The paper strips and polyester fibers are blended at a weight ratio of 30:70; the twisting direction is Z-twist; the twist is 1100 twists / meter, and a three-strand twisting process is adopted.

[0036] The characteristics of the product are as follows: yarn breaking strength: ≥280cN / tex; high strength, suitable for functional fabrics; good shape retention and excellent wrinkle resistance; strong durability of text information.

[0037] In addition, this application optimizes process parameters and controls product quality: 1. The effect of paper strip width on yarn properties:

[0038] 2. The effect of twist on visual effect:

[0039] 3. The effect of blending ratio on performance:

[0040] 4. Raw material control: Paper basis weight deviation: ±5%; Paper strip width deviation: ±0.1mm; Text printing clarity: ≥300dpi; 5. Process control: Twisting uniformity: CV value ≤ 5%; Twisting deviation: ± 5%; Yarn tension fluctuation: ± 10%; 6. Finished product inspection: No obvious fuzz or defects in appearance; strength meets design requirements; text integrity is ≥95% readability after unfolding.

[0041] The yarn with text disclosed in this application is the first to embed text information into yarn in a spiral structure, pioneering a new direction for yarn functionalization; the preparation process is simple, the equipment is universal (it can be produced using conventional twisting equipment, without the need for complex special equipment), and it is easy to industrialize; the raw material cost is low, and the production efficiency is high (diversified effects can be achieved by adjusting parameters such as twist, paper strip width, and blending ratio); it can realize the design concept of "profound meaning" and meet consumers' needs for cultural connotation; and it can use environmentally friendly inks and biodegradable paper, which is in line with the trend of sustainable development.

[0042] Overall, this technology has broad application potential in high-end apparel, home textiles, and specialty textiles, with a huge market potential. By adjusting parameters such as text content, yarn specifications, and weaving processes, a diverse range of products can be developed to meet the needs of different market segments. It is anticipated that after industrialization, the following product lines will be formed: Cultural Connotation Series: Embedding poems, classic quotes, etc. Commemorative Custom Series: Personalized text customization; Anti-counterfeiting Label Series: Brand anti-counterfeiting applications; Functional Series: Developing multifunctional products by combining intelligent fibers.
