Description

Technical Field

[0001] This utility model relates to fabric technology, and more specifically, to breathable and sun-protective woven fabrics. Background Technology

[0002] Curtains are an essential furniture item in summer. Most curtains are made of fabric. In current technology, in order to ensure the sun protection performance of the fabric, high-density woven fabric is usually used as the raw material for curtains to reduce the gaps between the yarns, thereby reducing the probability of light passing through the fabric.

[0003] While the above design effectively ensures the fabric's sun protection capabilities, it also makes it difficult for air to circulate between the inside and outside of the fabric, reducing its breathability and thus its applicability.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a breathable and sun-protective woven fabric.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a breathable and sun-protective woven fabric, comprising an outer layer and an inner layer, wherein the outer layer and the inner layer are fixed to each other by structural strips, the structural strips being arranged along the height direction of the inner layer, the outer layer comprising a first light-blocking part and a first breathable part spliced ​​vertically, and the inner layer comprising a second breathable part and a second light-blocking part spliced ​​vertically, wherein the area of ​​the first light-blocking part is larger than the area of ​​the second breathable part.

[0007] The present invention is further configured such that: the structural strip includes a plurality of adhesive strips located on the same straight line, and the distance between two adjacent adhesive strips on the same structural strip is greater than the length of the adhesive strip.

[0008] The present invention is further configured such that: both the first light-shielding part and the second light-shielding part are made of sun-protective yarn woven into a plain weave, and both the first breathable part and the second breathable part are made of structural yarn woven into a perforated weave.

[0009] The present invention is further configured such that: the sun protection yarn comprises two strands of polyester yarn spirally wound together, and the outer peripheral wall of the polyester yarn is provided with a plurality of spherical protrusions.

[0010] The present invention is further configured such that the twist of the two polyester yarns is between 570 twists / meter and 630 twists / meter.

[0011] The present invention is further configured such that: the polyester yarn is formed by twisting several irregularly shaped polyester fibers, the cross section of the irregularly shaped polyester fibers is double cross-shaped, and the structural yarn is formed by twisting several aramid fibers.

[0012] In summary, this utility model has the following beneficial effects:

[0013] When curtains are made from this woven fabric, the first blackout section prevents sunlight from passing through the outer layer. Some sunlight that passes through the first ventilation section can be blocked by the second blackout section on the inner layer, thus effectively preventing sunlight from passing through the woven fabric. The arrangement of the first and second ventilation sections allows air to exchange between the two sides of the woven fabric, thereby ensuring the breathability of the woven fabric. The structural strips arranged along the height of the inner layer can ensure the stability of the connection between the inner and outer layers without having too much impact on the horizontal bending of the woven fabric, making it convenient for people to pull the curtains made from this woven fabric.

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] Breathable and sun-protective woven fabric, such as Figure 1 As shown, the curtain includes an outer layer and an inner layer, which are fixed together by structural strips. The structural strips are set along the height direction of the inner layer. The outer layer includes a first light-blocking part 1 and a first ventilation part 2 spliced ​​vertically, and the inner layer includes a second ventilation part 4 and a second light-blocking part 3 spliced ​​vertically. The area of ​​the first light-blocking part 1 is larger than the area of ​​the second ventilation part 4, and the area of ​​the first light-blocking part 1 is greater than or equal to the area of ​​the second light-blocking part 3. When the curtain is made of this woven fabric, the first light-blocking part 1 can prevent sunlight from passing through the outer layer, and some sunlight that passes through the first ventilation part 2 can be blocked by the second light-blocking part 3 on the inner layer, thereby effectively preventing the possibility of sunlight passing through the woven fabric. The setting of the first ventilation part 2 and the second ventilation part 4 allows air to be exchanged on both sides of the woven fabric, thereby ensuring the breathability of the woven fabric. The structural strips set along the height direction of the inner layer can ensure the stable connection between the inner and outer layers without having too much impact on the horizontal bending of the woven fabric, making it convenient for people to pull the curtain made of this woven fabric.

[0020] like Figure 1 and Figure 2 As shown, the structural strip includes several adhesive strips 5 located on the same straight line. These adhesive strips 5 are fixedly connected to the inner and outer layers by hot melt adhesive. The distance between two adjacent adhesive strips 5 on the same structural strip is greater than the length of the adhesive strip 5. This arrangement allows adjacent adhesive strips 5 to be separated. When the woven fabric is folded and stored horizontally, the inner and outer layers can be bent along the separation points of adjacent adhesive strips 5, reducing the impact of the structural strip on the bending and storage of the woven fabric. The first light-blocking part 1 and the second light-blocking part 3 are both woven with sun-protective yarn to form a plain weave structure. Specifically, the warp and weft sun-protective yarns are woven by a loom to form the first light-blocking part 1 and the second light-blocking part 3, respectively. The first breathable part 2 and the second breathable part 4 are both woven with structural yarn 6 to form a perforated structure. Specifically, the first breathable part 2... Similar to the weaving pattern of the second breathable part 4, the first breathable part 2 and the second breathable part 4 are woven together in one go by a shuttle loom. Assuming that the warp weft weft point on the perforated structure is floating and the weft weft point is sinking, the cycle of the perforated structure is sinking-float-float-float-float-float, floating-float-float-sinking-sinking, sinking-float-float-float-float, floating-sinking-float-float-float, sinking-float-float-float-sinking, sinking-sinking-float-float, sinking-sinking-float-float, sinking-sinking-float-float, sinking-sinking-float-float, floating-sinking-float-float, sinking-sinking-float-float, floating-sinking-float-float. This setting allows the floating point of the warp structural yarn 6 on the perforated structure to restrict the weft structural yarn 6, making it difficult for adjacent weft structural yarns 6 to get close to each other, thereby ensuring the formation of holes on the first breathable part 2 and the second breathable part 4. Similarly, the sinking point of the weft structural yarn 6 on the perforated structure can also restrict the warp structural yarn 6, thereby better ensuring the air permeability of the first breathable part 2 and the second breathable part 4.

[0021] like Figure 3As shown, the sun-protective yarn comprises two strands of polyester yarn 7 spirally wound together. The polyester yarn 7 possesses excellent sun-protective properties, effectively ensuring the sun-protective yarn's ability to block sunlight. Several spherical protrusions 8 are provided on the outer periphery of the polyester yarn 7. Specifically, during the manufacturing process, by changing the feed speed, different twist zones are formed on the outer periphery of the single-strand polyester yarn 7. The areas with higher twist form spherical protrusions 8. When weaving to form the first light-blocking part 1 or the second light-blocking part 3, the spherical protrusions 8 can effectively conceal the gaps between adjacent sun-protective yarns, thereby reducing the possibility of sunlight passing through the first light-blocking part 1 or the second light-blocking part 3, ensuring the sun-blocking ability of the first light-blocking part 1 and the second light-blocking part 3. The twist of the two polyester yarns 7 is between 570 twists / meter and 630 twists / meter. This design results in a relatively high twist of the sun-protective yarn. Polyester yarns 7 twisted together at this twist level are less prone to deformation under external force, ensuring the first light-blocking part 1 or... The second light-shielding part 3 is not easily deformed when stretched, thus ensuring the service life of the first light-shielding part 1 or the second light-shielding part 3. The polyester yarn 7 is made of several irregularly shaped polyester fibers twisted together. The cross-section of the irregularly shaped polyester fibers is double cross-shaped. When twisted, the irregularly shaped polyester fibers with double cross-sections have more edges and grooves on their surface, which can increase the contact area and mechanical interlocking effect between the irregularly shaped polyester fibers. This structure makes the irregularly shaped polyester fibers inside the polyester yarn 7 more tightly entangled, reducing the possibility of the irregularly shaped polyester fibers slipping in the polyester yarn 7 when subjected to external force, and ensuring the tensile strength of the polyester yarn 7. The structural yarn 6 is made of several aramid fibers twisted together. Aramid fibers have high mechanical strength, so that the first air-permeable part 2 or the second air-permeable part 4 is not easily stretched and deformed at the position of the holes in the first air-permeable part 2 or the second air-permeable part 4 when stretched, thus better ensuring the shape of the first air-permeable part 2 or the second air-permeable part 4.
