Description

Technical Field

[0001] The utility model relates to the technical field of wool sweaters, in particular to a warm wool sweater. Background Art

[0002] The wool sweaters we wear daily are all woven from various types of knitted yarns. They are soft, wrinkle-resistant and breathable, and have great ductility and elasticity. They are comfortable to wear and have a wide range of users. Most wool sweaters are single-layer structures, but in order to keep out the cold in winter, wool sweaters need to be more warm, and thicker yarns are often used to weave them, which increases the thickness and weight of the sweaters, giving the wearer a heavy feeling. In addition, due to the characteristics of the wool sweater weaving structure, there are ventilation gaps between the coils, which are easy to ventilate when worn alone. Even if worn with other clothes, cold wind can easily pass through the gaps between the clothing fabrics to reach the skin surface, making the wearer feel cold. Utility Model Content

[0014] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0015] Combination Figure 1 This embodiment is described in detail. A warm wool sweater includes: a sweater body, the sweater body is a wool knitted fabric; the wool knitted fabric includes a composite windproof fabric layer 1, a warm fabric layer 2 and a close-fitting fabric layer 3; the warm fabric layer 2 is arranged between the windproof fabric layer 1 and the close-fitting fabric layer 3; the close-fitting fabric layer 3 is a velvet fabric. Specifically, each layer of the wool knitted fabric is composited by a mesh hot melt adhesive.

[0016] Furthermore, the velvet fabric is woven from yarns twisted together with velvet yarn and spandex core-spun yarn.

[0017] Specifically, in this embodiment, the taffeta yarn is a 14.5tex taffeta acrylic, cotton, and modal blended yarn (40:30:30). The taffeta acrylic is an ultra-fine shaped acrylic. The dumbbell-shaped cross-section makes it difficult for individual fibers to gather tightly, increasing the static air between the fibers. Under the same quality, the thermal insulation performance can be 20% higher than that of wool; at the same time, its fineness is lower than 0.9dtex, and there are a large number of capillary areas between individual fibers, which have good water wicking ability, can quickly guide the moisture generated by the body, keep the skin dry for a long time, and keep the heat in the moisture in the body, thereby realizing the warm-keeping function of the fabric absorbing moisture and heating; the spandex core-spun yarn is a polyester-spandex core-spun yarn or a cotton-spandex core-spun yarn. The yarn twisted with the taffeta yarn and the spandex core-spun yarn has a soft feel, good skin-friendliness, good elasticity, can adapt to human activities, and has a good warm-keeping effect.

[0018] Furthermore, the windproof fabric layer 1 includes a polyurethane nanofiber membrane and an elastic fabric layer; the elastic fabric layer is arranged on a side close to the thermal insulation fabric layer; the elastic fabric layer is woven from cotton-spandex core-spun yarn. The polyurethane nanofiber membrane is prepared by a large-width, high-uniformity electrospinning machine and a high-speed spinning solution developed by the Institute of Process Engineering, Chinese Academy of Sciences. The cotton-spandex core-spun yarn has spandex filaments as the core and is coated with cotton fibers on the outside. The polyurethane nanofiber membrane is composited with the elastic fabric woven from the cotton-spandex core-spun yarn, which is more comfortable and soft, and is elastic, environmentally friendly, light, wear-resistant, waterproof and breathable. It fully realizes multiple protections, which are both windproof and waterproof, and can timely discharge sweat and moisture emitted from the body.

[0019] Furthermore, the thermal insulation fabric layer 2 is woven from thermal insulation yarns, which are twisted from wool yarns and hygroscopic and heat-generating conductive fiber yarns; the hygroscopic and heat-generating conductive fiber includes an inner layer 4 and an outer layer 5, the inner layer is a conductive masterbatch, and the outer layer is hygroscopic and heat-generating polyester. The hygroscopic and heat-generating conductive fiber is a skin-core structure, has good hygroscopic and heat-generating properties and conductive properties, achieves a permanent antistatic effect, and solves the problem that the hygroscopic and heat-generating fabric must be twisted and coated with ordinary conductive fibers to eliminate static electricity.

[0020] Furthermore, a thermal insulation fabric layer 6 is provided between the thermal insulation fabric layer 2 and the windproof fabric layer 1 .

[0021] Furthermore, the thermal insulation fabric layer 6 is woven from aerogel fiber yarns. Aerogel is a three-dimensional mesh nanoporous material, which is generally prepared by a sol-gel process. Drying techniques such as supercritical extraction are used to extract the solvent while maintaining the three-dimensional framework structure of the gel to the maximum extent, thereby completing the replacement of air and solvent. The unique nanoporous structure makes its porosity extremely high and its density ultra-low, showing characteristics such as high specific surface area, low thermal conductivity, excellent insulation and heat insulation. Since the thermal insulation performance of the fiber material is proportional to the static air content inside the fiber material, inversely proportional to the fiber diameter, and inversely proportional to the overall material density, aerogel fiber is a fiber with the best thermal insulation effect.

[0022] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
