Abstract
Description
Technical Field
[0001] This application relates to the field of fabric technology, and specifically discloses a silk elastic fabric. Background Technology
[0002] While traditional silk fabrics offer advantages such as moisture absorption, breathability, and skin-friendliness, they also suffer from insufficient elasticity, easy wrinkling, and limited functionality. Current technologies address these issues by adding spandex or Lycra fibers to enhance elasticity in some elastic fabrics, but this may sacrifice the natural properties of silk. Others utilize multi-layered composite structures (such as negative ion fiber layers and antibacterial layers) to enhance functionality, but these processes are complex and costly.
[0003] In view of this, the inventors have provided a silk elastic fabric to solve the above problems. Utility Model Content
[0004] This invention provides a simple and easy-to-process silk elastic fabric that combines elasticity, moisture absorption and breathability, antibacterial and bacteriostatic properties with comfort, meeting the needs of high-end clothing and healthy textiles.
[0005] To achieve the above objectives, the basic solution of this utility model provides a silk elastic fabric, comprising a silk outer layer woven from mulberry silk with an anti-wrinkle treatment on the surface; an elastic support layer disposed below the silk outer layer, the elastic support layer being composed of spandex and polyester composite fibers interwoven; a moisture-absorbing and antibacterial layer disposed below the elastic support layer, the moisture-absorbing and antibacterial layer being woven from silver-plated cotton fiber and modal fiber blended yarn; and a base layer disposed below the moisture-absorbing and antibacterial layer, the base layer being a flax fiber nonwoven fabric, which is bonded to the moisture-absorbing and antibacterial layer by hot melt adhesive; the layers are fixed together by ultrasonic pressing and partial sewing.
[0006] Furthermore, the elastic support layer has a warp elongation of ≥20% and a weft elongation of ≥18%.
[0007] Furthermore, the blending ratio of modal fiber to silver-plated cotton fiber in the moisture-absorbing and antibacterial layer is 1:1 to 3:1.
[0008] Furthermore, the fabric has a weight of 90~120g / m², a thickness of 0.25~0.35mm, an elastic recovery rate of ≥85%, and an air permeability of ≥500L / m² / s.
[0009] Furthermore, the basis weight of the flax fiber nonwoven fabric in the base layer is 30~50 g / m.
[0010] Furthermore, the spandex accounts for 15% to 20% of the total mass.
[0011] Furthermore, the thickness of the silver-plated cotton fiber is 0.1~0.3μm.
[0012] The principle and effect of this basic scheme are as follows:
[0013] 1. Enhanced elasticity and comfort in tandem:
[0014] The spandex-polyester composite structure of the elastic support layer achieves bidirectional elasticity (warp ≥20%, weft ≥18%) and high recovery rate (≥85%), taking into account both movement extensibility and deformation resistance, and avoiding the wrinkle-prone defects of traditional silk fabrics.
[0015] 2. Highly effective antibacterial and moisture-wicking properties:
[0016] The nanoscale coating (0.1~0.3μm) of silver-plated cotton fibers gives the fabric broad-spectrum antibacterial properties, and the moisture absorption rate of modal fibers is greatly improved compared with pure cotton, effectively reducing sweat retention and keeping the fabric dry to the touch.
[0017] 3. Environmentally friendly processing and structural stability:
[0018] Ultrasonic pressing is used to replace chemical adhesives, avoiding interlayer hardening problems. At the same time, local stitching enhances structural strength and improves fabric peel strength.
[0019] 4. Multifunctional composite advantages:
[0020] The combination of a silk outer layer and a linen base layer offers natural antibacterial properties, moisture absorption and breathability, and a crisp texture. The optimized design of weight (90~120g / m²) and thickness (0.25~0.35mm) makes it suitable for clothing needs in all four seasons. Attached Figure Description

[0029] Elastic support layer 2: It is made of spandex (18% by weight) and fine denier polyester (82% by weight) in a 2:1 warp and weft ratio, with a warp elongation of 22%, a weft elongation of 19%, and an elastic recovery rate of 88%.
[0030] Moisture-absorbing and antibacterial layer 3: The silver-plated cotton fiber coating is 0.2μm thick and blended with modal fiber in a 2:1 ratio. The yarn count is 40S, and the actual measured moisture absorption rate is 0.35g / (cm²·h), which is significantly improved compared with pure cotton (0.27g / (cm²·h)).
[0031] Base layer 4: Linen nonwoven fabric with a weight of 40g / m² is bonded to the moisture-absorbing and antibacterial layer by low-melting-point polyester hot melt adhesive (melting point 110℃).
[0032] 2. Processing technology
[0033] Interlayer lamination: Ultrasonic pressing machine (frequency 30kHz, pressing gap 8mm), pressing temperature 80℃, pressure 0.4MPa, pressing time 3s; local areas are stitched with high-strength polyester thread in a Z-shape with a stitch spacing of 2mm.
[0034] Finishing: The fabric is pre-shrinked (shrinkage rate controlled within 3%) and impregnated with a hydrophilic softener to improve surface smoothness.
[0035] Example 2: Implementation of the High-Elasticity, Lightweight and Thin Type
[0036] 1. Structural optimization
[0037] Elastic support layer 2: The proportion of spandex is increased to 20%, and it adopts the structure of ultra-fine polyester 0.8D and spandex core-spun yarn. The warp elongation reaches 25% and the weft elongation is 21%. The fabric weight is reduced to 95g / m² and the thickness is 0.28mm.
[0038] Base layer 4: Replace with 30g / m² linen nonwoven fabric, and reduce the amount of hot melt adhesive coating by 15%.
[0039] 2. Performance advantages

[0045] Base layer 4: Linen nonwoven fabric impregnated with tea polyphenol extract (concentration 2%) to further enhance natural antibacterial properties.
[0046] 2. Test Results
[0047] Antibacterial rate: The antibacterial rate against Candida albicans reaches 99.2%, and the antibacterial durability is improved (the antibacterial rate is still ≥98% after 50 washes).
[0048] Comfort: The fabric has a static voltage half-life of <1s (GB / T 12703.1-2021) and excellent antistatic properties.
[0049] Example 4: Low-cost implementation
[0050] 1. Material replacement
