Description

Technical Field

[0001] This utility model relates to a brushed fabric, and more particularly to a heat-retaining and warm three-dimensional fleece double-sided brushed fabric. Background Technology

[0002] Because natural fibers, such as cotton or linen, are relatively soft and comfortable, fabrics made from them are generally more comfortable. However, cotton fibers have relatively high thermal conductivity, causing heat to dissipate easily, thus its warmth retention is not as good as that of fabrics specifically designed for warmth. Therefore, the use of pure natural fiber fabrics has decreased in situations where warmth is required.

[0003] Therefore, people use wool or cashmere to weave fabrics in order to provide better warmth. However, production cannot keep up with demand, wool or cashmere is expensive, and wool or cashmere fabrics have high requirements for washing and other aspects.

[0004] Thus, synthetic fibers, such as polyester or acrylic, were developed. While they offer good warmth retention, they are not as comfortable as natural fibers. Polyester does not wick away moisture easily, making people feel stuffy and unbreathable. Acrylic is less soft and comfortable, and can cause friction. Moreover, synthetic fibers also have static electricity issues, easily attracting and affecting their warmth retention.

[0005] Therefore, the existing fabric was improved by brushing the surface to create a velvety effect, which means that short fibers are formed on the fabric surface. Short fibers have better softness and comfort. After brushing, the fabric has a thicker feel, but it still maintains good breathability. An air layer is formed in the short fiber area of ​​the fabric, which can reduce heat loss.

[0006] However, short pile is mostly formed through a brushing process, which breaks the fibers and may cause loose fibers. After repeated washing, it is easy for the fibers to fall out, affecting its wearability.

[0007] When the fabric forms a fuzzy texture on its surface, it is prone to snagging when in contact with other items, causing the fuzz to be pulled and making it easier for the snagged fuzz to fall off. Summary of the Invention

[0008] This utility model discloses a heat-retaining and warm three-dimensional fleece double-sided brushed fabric. The overall structure adopts a multi-layer structure, with the middle layer being a heat-retaining layer to increase the fabric's heat storage capacity. The outer surface of the fabric has a three-dimensional fleece structure that is a mixture of short and long fleece, which is soft and comfortable and also forms an air layer on the fabric surface to improve the warmth retention effect. The fleece is spiral-shaped, which can reduce the chance of snagging and shedding. The inner surface of the fabric has short fleece, which makes the fabric have a good skin-friendly feel.

[0009] The specific technical solution of this utility model is as follows: a heat-retaining and warm three-dimensional fleece double-sided brushed fabric, which adopts a three-layer structure, namely an inner layer, a middle layer and an outer layer. The inner layer is woven from natural cotton fiber yarn, and the surface of the inner layer is brushed to form short pile. The middle layer is a heat-retaining layer structure woven from heat-retaining microcapsule hollow fiber yarn. The outer layer is woven from polyester-cotton fiber yarn, and the surface of the outer layer is brushed to form a three-dimensional fleece structure with alternating short and long pile.

[0010] Both the inner and outer layers of the fabric have a pile structure, with over 1 million pile fibers per square meter. This creates a sufficient air layer on the fabric surface, enhancing its warmth retention. The inner layer generally faces inwards and features short pile fibers for improved comfort. The outer layer generally faces outwards and has more contact with the outside environment. Its pile structure consists of alternating short and long pile fibers, ensuring warmth while maintaining breathability. The middle layer is a heat-retaining layer woven from heat-retaining microcapsule hollow fiber yarn, giving the fabric its own heat-retaining function and further enhancing its warmth retention. The heat-retaining microcapsule hollow fiber yarn combines heat-retaining microcapsules and hollow fibers.

[0011] Preferably, the outer layer of the fabric has a jacquard textured surface, while the inner layer has a flat surface. Using a jacquard textured surface on the outer layer allows for the formation of varying pile lengths on the jacquard textured surface during napping due to differences in contact area and force with the napping tool. This alternation of long and short pile creates a three-dimensional pile structure.

[0012] Preferably, the outer layer of the fabric has short pile on the convex parts and long pile on the concave parts. The short pile on the convex parts of the outer surface of the fabric is less likely to get caught, and the dense arrangement makes the overall structure more compact, making it less likely that a single pile will be easily pulled out.

[0013] Preferably, the short and long fibers are spiral-shaped, with the spiral height of the short fibers being 0.3-0.5 mm and the spiral height of the long fibers being 0.5-0.9 mm. The spiral shape of the fibers gives them stretch elasticity, which reduces the chance of snagging and shedding.

[0014] Preferably, the jacquard textured surface is wavy or segmented, with both concave and convex surfaces arranged in blocks, and the concave and convex surfaces spaced alternately. The distribution of the textured structure on the outer surface of the fabric gives it a decorative feel, and the pile formed on the textured surface can be distributed along with the outer surface of the fabric, thus creating changes in light and shadow.

[0015] Preferably, the polyester-cotton fiber yarn used for the outer layer of the fabric has a core-spun yarn structure, with an overall circular shape. The core of the yarn is made of polyester fiber, and multiple strands of natural cotton fiber are spirally wrapped around the outside of the core. To obtain a larger pile structure, the yarn fibers will be broken during abrasion. To improve the stability of the pile, the yarn of the outer layer of the fabric is woven from polyester-cotton fiber yarn. The core of the polyester-cotton fiber yarn is made of polyester fiber, which has high strength and elasticity. The natural cotton fiber has good skin-friendliness and breathability. The polyester fiber underlay can improve the stability of the pile after brushing.

[0016] Preferably, the natural cotton fiber filaments are three strands, which are spirally wrapped side by side, and each natural cotton fiber filament includes three cotton fiber monofilaments.

[0017] Preferably, the outer surface of the yarn core is provided with a spiral groove, which has three ends and corresponds to three strands of natural cotton fibers.

[0018] The beneficial effects of this utility model are: 1. Both the inner and outer layers of the fabric have a pile structure, with more than 1 million piles per square meter of fabric surface. This creates a sufficient air layer on the fabric surface, which can effectively increase the amount of static air between the fabric and the skin, control the amount of adhesion on the fabric surface, reduce heat loss, and thus improve the warmth retention effect.

[0019] 2. The inner layer of the fabric usually faces inward. The pile of the inner layer of the fabric is short pile. The short pile feels soft and comfortable when it comes into contact with the skin, thus improving the contact comfort of the inner layer of the fabric.

[0020] 3. The outer layer of the fabric generally faces outward and has more contact with the outside. The outer layer of the fabric has a three-dimensional pile structure with alternating short and long pile. This ensures the warmth of the pile air layer while giving the fabric appropriate breathability, thus balancing preservation effect with breathability.

[0021] 4. The middle layer of the fabric is a heat-storage layer structure, woven from heat-storage microcapsule hollow fiber yarn, which gives the fabric its own heat-storage function and improves the fabric's warmth retention effect. The heat-storage microcapsule hollow fiber yarn is made by combining heat-storage microcapsules and hollow fibers. Attached Figure Description
