Abstract
Description
Technical Field
[0001] This invention relates to the field of blankets, and more particularly to a velvet blanket that can trap dust. Background Technology
[0002] Velvet is a very common material for blankets, especially carpets and furniture throws. The pile of these blankets is upright or parallel and slanted, making it difficult to trap dust. Furthermore, due to waterproofing and anti-static treatments, some dust particles are "bounced" off before even reaching the surface, or only touch the surface. This anti-static and dust-resistant property makes velvet blankets easy to keep clean, but the dust still floats in the air. After a period of use, a thick layer of dust accumulates on the velvet blanket, requiring very careful removal for cleaning. Otherwise, shaking off the dust will cause it to fly everywhere again, causing secondary environmental pollution and harm to people's health. Therefore, people desire a type of velvet blanket that can absorb dust but is less prone to shedding. Summary of the Invention

[0028] S5. Finish and apply flame retardant treatment.
[0029] Compared with existing technologies, this invention has the following beneficial technical effects: The blanket is formed by fixing the warp yarns to the upper and lower base fabrics with four wefts and then cutting them. This results in a dense, three-dimensional pile with interwoven fibers. Blankets made of this type of pile are resistant to rubbing and do not shed easily. Dust easily falls into the pile and is trapped by the interwoven fibers, preventing it from floating away. The interwoven fibers are composed of wool and chlorofiber warp yarns, which easily generate static electricity through friction. This static electricity is used to attract dust, purifying the air and trapping dust particles. Finally, it is manually washed, dried, and reused. Both the upper and lower base fabrics are composed of cotton yarn, which has poor conductivity, allowing the static electricity to maintain a certain energy level, achieving the dust-attracting effect. Therefore, the effect of this velvet blanket is significant. After flame-retardant treatment, it is very popular in the market and is worthy of promotion and use. Attached Figure Description

[0034] like Figure 1 As shown, the present invention proposes a velvet blanket capable of trapping dust, comprising an upper base fabric, a lower base fabric, and pile warp yarns. The pile warp yarns are first woven together with the upper (lower) base fabric using four-weft bonding; then returned to the lower (upper) layer and woven together with the lower (upper) base fabric using four-weft bonding; then returned to the upper (lower) layer again, and so on, repeating this process; finally, the pile warp yarns are cut and split from the middle of the upper and lower base fabrics to form an upper velvet blank and a lower velvet blank; finally, after finishing and flame-retardant treatment, the velvet blanket is obtained; the pile of the upper and lower velvet blanks is interlaced and inclined.

This process of threading the heddles and inserting the reed is repeated.
[0041] S3, weaving with heddle shears and shuttle insertion.
[0042] First shuttle: The upper second warp yarn T... 上2 Lift it upwards, and place the first warp yarn of the lower layer T. 下1 Lift the yarn upwards, raising the first pile warp yarn R1 and lowering the third pile warp yarn R3. Place the second pile warp yarn R2 and the fourth pile warp yarn R4 in the middle. Then insert the second weft yarn W from the upper layer. 上1 The second weft yarn of the lower layer W 下1 , weft weaving;
[0043] Second shuttle: The upper layer of first warp yarn T... 上1 Lift it upwards, and place the second warp yarn T on the lower layer. 下2 Lift up, raise the second pile warp yarn R2, lower the fourth pile warp yarn R4, place the first pile warp yarn R1 and the third pile warp yarn R3 in the middle, and then insert the upper second weft yarn W. 上2 The second weft yarn in the lower layer W 下2 weft weaving;

[0045] Fourth shuttle: The first warp yarn of the upper layer T 上1 Lift it upwards, and place the second warp yarn T on the lower layer. 下2 Lift upwards, raising the third and fourth pile warp yarns R3 and R2, while lowering the first and second pile warp yarns R1 and R2, and wefting in the upper fourth weft yarn W. 上4 The fourth weft yarn in the lower layer W 下4 weft weaving;
[0046] Fifth shuttle: The second warp yarn of the upper layer T 上2 Lift it upwards, and place the first warp yarn of the lower layer T. 下1 Lift up, raise the third pile warp yarn R3, lower the first pile warp yarn R1, place the second pile warp yarn R2 and the fourth pile warp yarn R4 in the middle, and shuttle in the upper fifth weft yarn W. 上5 The fifth weft yarn in the lower layer W 下5 weft weaving;
[0047] Sixth shuttle: The first warp yarn of the upper layer T 上1 Lift it upwards, and place the second warp yarn T on the lower layer. 下2 Lift the fourth pile warp yarn R4 upwards, lower the second pile warp yarn R2, place the first pile warp yarn R1 and the third pile warp yarn R3 in the middle, and then weave in the upper sixth weft yarn W. 上6 The sixth weft yarn in the lower layer W 下6 weft weaving;
[0048] Seventh shuttle: The second warp yarn of the upper layer T 上2 Lift it upwards, and place the first warp yarn of the lower layer T. 下1 Lift upwards, raise the third and fourth pile warps, and lower the first and second pile warps into the upper seventh weft yarn W. 上7 The seventh weft yarn in the lower layer W 下7 weft weaving;
[0049] Eighth shuttle: The first warp yarn of the upper layer T 上1 Lift it upwards, and place the second warp yarn T on the lower layer. 下2 Lift the first pile warp yarn R1 and the second pile warp yarn R2 upwards, and lower the third pile warp yarn R4 and the fourth pile warp yarn R4 downwards, then insert the upper eighth weft yarn W. 上8 The eighth weft yarn in the lower layer W 下8 weft weaving;
[0050] At this point, the weaving of one unit consisting of eight shuttles is completed, and the weaving process is repeated in this cycle.
[0051] S4. Use a velvet cutter to cut and split the connecting velvet in the middle of the upper and lower base fabrics to form an upper velvet blank and a lower velvet blank.
[0052] S5. Finish and apply flame retardant treatment.
[0053] Because the pile of the velvet blanket in this invention is secured by four weft threads, and each reed tooth uses only one warp yarn, while the other reed tooth also uses only one warp yarn, forming an interlocking structure that locks in the weft yarns, resulting in a densely piled velvet blanket. After the pile is secured, it has a strong three-dimensional effect. Furthermore, the pile of the first reed tooth is compressed by the weft yarn and tilts in one direction, while the pile of the second reed tooth is compressed by the weft yarn and tilts in another direction, thus forming interwoven pile (e.g., ...). Figure 1 (As shown). Blankets made of such pile are resistant to rubbing and do not shed easily. Moreover, dust easily falls into the pile and is locked in by the interlaced pile, making it less likely to drift out.
[0054] Taking the first pile warp R1 of the first reed tooth as an example, the first pile warp R1 passes through the upper eighth weft yarn W of the previous unit. 上8 Then, it was woven into the first weft yarn of the upper layer. 上1 Upper layer second weft yarn W 上2 The third weft yarn in the upper layer W 上3 After being solidified in a W-shape, it passed through the fourth weft yarn of the upper layer. 上4 Then, one end of the cut pile is tucked by the eighth weft yarn of the upper layer of the previous unit. 上8 Squeezed to the left, the other end is then pressed by the fourth weft yarn W on the upper layer. 上4 It is also squeezed to the left, so that both ends of the fluff tilt to the left as shown in the figure.
[0055] Taking the second pile warp R2 of the second reed tooth as an example, the second pile warp R2 passes through the upper seventh weft yarn W of the previous unit. 上7 Then, it was the eighth weft yarn W of the upper layer of the previous unit. 上8， Upper layer first weft yarn W 上1 Upper layer second weft yarn W 上2 After being consolidated in a W-shape, the third weft yarn in the upper layer W... 上3 Then, one end of the cut pile is covered by the upper seventh weft yarn W. 上7 Squeezed to the right, the other end is then pressed by the third weft yarn W on the upper layer. 上3 Squeeze to the right, causing the two ends of the fluff to tilt to the right as shown in the diagram. The mutually tilted fluff will then cross each other like an open net, swallowing and locking in the falling dust, preventing it from floating away without washing.
[0056] Since the first and second pile warps R1 and R2 are made of wool, and the third and fourth pile warps R3 and R4 are made of chlorofiber, the first pile warp R1 of the first reed tooth, the third pile warp R3 of the third reed tooth, and the second pile warp R2 and fourth pile warp R4 of the second reed tooth are all interwoven pile warps of wool and chlorofiber. From a physical perspective, wool is a material that readily gains electrons through friction, while chlorofiber is a synthetic fiber that also readily gains electrons through friction. Therefore, the stronger the ability to gain electrons, the easier it is to generate static electricity. This static electricity generated through friction easily attracts dust, which is exactly what we need. The interwoven pile uses this static electricity to attract dust, purifying the air and locking in dust particles, preventing them from floating. Finally, it is manually washed, dried, and reused.
[0057] To protect this hard-won static electricity, we will...

Cotton yarn has poor electrical conductivity, allowing static electricity to maintain a certain amount of energy, achieving a dust-attracting effect. Therefore, the effect of this velvet blanket is obvious, and after flame-retardant treatment, it is very popular in the market. It is worth promoting and using!
[0058] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
