Velvet door seam strip and production method thereof

Abstract

The present invention discloses a velvet door seam strip and a production method thereof. The velvet door seam strip is formed by cutting and finishing an upper base fabric and a lower base fabric, which are consolidated by a middle layer of velvet warp. The upper weft yarns in the upper base fabric include the first upper weft yarn to the thirtieth upper weft yarn, and the lower weft yarns in the lower base fabric include the first lower weft yarn to the thirtieth lower weft yarn. The middle velvet warp includes middle layer A velvet warp and middle layer B velvet warp, which are yarns that swell when exposed to water. The first upper weft yarn to the twelfth upper weft yarn, the first lower weft yarn to the twelfth lower weft yarn, the nineteenth upper weft yarn to the thirtieth upper weft yarn, and the nineteenth lower weft yarn to the thirtieth lower weft yarn are all low-melting-point chemical fibers. Due to the use of water-swelling materials, the combined weaving method of full and half raising, and the use of low-melting-point materials for the overlapping weft yarns, the velvet door seam strip of the present invention not only perfectly meets user needs but also can block smoke in special environments.

Description

Technical Field

[0001] The invention relates to the technical field of velvet weaving, in particular to a velvet door seam strip and a production method thereof. Background Art

[0002] Currently, building energy consumption in my country accounts for 25-30% of total final energy consumption, while energy lost through gaps around loosely sealed doors and windows accounts for approximately 38% of this total. Therefore, improving the sealing performance of door and window gaps is crucial for energy conservation. However, gaps between doors and windows are essential, as they facilitate the flow of people and air, and symbolize vitality. Managing these gaps is crucial. Nano-silver sealing strips are already available, offering environmental protection, energy savings, antibacterial and mildew-resistant properties, and are weather-resistant, flexible, and wear-resistant. However, they lag behind in preventing smoke and fire, leading to a desire for better door gap strips. Summary of the Invention

DETAILED DESCRIPTION

[0073] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0074] Combine Figures 1 to 5 The present invention is described in detail. Door strips are required to prevent cold air intrusion in winter, cool air loss from indoor air conditioning in summer, sand and dust intrusion, mosquitoes and flies, and outdoor noise. They also reduce the clatter of opening and closing doors and windows, and prevent the intrusion of smoke, fire, and other hazards. While nanosilver seals cannot withstand all of these challenges, the velvet door strips of the present invention can meet these requirements in a comprehensive manner.

[0075] The present invention relates to a method for producing velvet door seam strips, wherein the velvet door seam strips are formed by cutting and splitting an upper base cloth and a lower base cloth consolidated by a middle layer of velvet warp, and then finishing the upper base cloth; the velvet door seam strips include a left end ZU of the door seam strip, a middle ZH of the door seam strip, and a right end YO of the door seam strip.

[0076] The upper base cloth is formed by interweaving upper warp yarns Tupper, upper pile warp and upper weft yarns, and the lower base cloth lower layer is formed by interweaving lower warp yarns Tlower, lower pile warp and lower weft yarns.

[0077] The upper layer of pile warps includes the upper first pile warp R1, the upper layer a pile warp R1-a, the upper layer b pile warp R1-b, and the upper layer c pile warp R1-c; the upper layer of weft yarns includes the upper first weft yarn W1 to the upper thirtieth weft yarn W30.

[0078] The lower layer pile warp is composed of the lower layer first pile warp R1, the lower layer a pile warp R1-a, the lower layer b pile warp R1-b, and the lower layer c pile warp R1-c; the lower layer weft yarns include the lower layer first weft yarn W1 to the lower layer thirtieth weft yarn W30. The middle layer pile warp includes the middle layer A pile warp RA and the middle layer B pile warp RB.

[0079] The first weft yarn W1 to the twelfth weft yarn W112 of the upper layer are interwoven with the upper warp yarns T1 and the upper velvet warp to form the left end ZU of the velvet door seam strip, referred to as the left end weft yarn of the velvet door seam strip. The thirteenth weft yarn W13 to the eighteenth weft yarn W18 of the upper layer are woven in a circular pattern according to the thickness of the door and window to form the middle of the velvet door seam strip, referred to as the middle weft yarn of the velvet door seam strip. The nineteenth weft yarn W19 to the thirtieth weft yarn W30 of the upper layer are interwoven with the upper warp yarns and the upper velvet warp to form the right end of the velvet door seam strip, referred to as the right end weft yarn of the velvet door seam strip. Similarly, since the upper base fabric is woven symmetrically with the lower base fabric, The first weft yarn W1 of the lower layer to the twelfth weft yarn W12 of the lower layer can also be called the left weft yarn of the velvet door seam strip, the thirteenth weft yarn W13 of the lower layer to the eighteenth weft yarn W18 of the lower layer can also be called the middle weft yarn of the velvet door seam strip, and the nineteenth weft yarn W19 of the lower layer to the thirtieth weft yarn W30 of the lower layer can also be called the right weft yarn of the velvet door seam strip.

[0080] The first weft yarn W1 of the upper layer to the twelfth weft yarn W12 of the upper layer, the first weft yarn W1 of the lower layer to the twelfth weft yarn W12 of the lower layer, the nineteenth weft yarn W19 of the upper layer to the thirtieth weft yarn W30 of the upper layer, and the nineteenth weft yarn W19 of the lower layer to the thirtieth weft yarn W30 of the lower layer are all low-melting-point sheath-core chemical fiber yarns; the middle layer A velvet warp RA and the middle layer B velvet warp RB are yarns that expand when exposed to water.

[0081] Furthermore, the low melting point sheath-core chemical fiber yarn is selected from low melting point polyester. The yarn that swells when exposed to water is a yarn that is used in the sewing of umbrellas and tents and blocks the needle holes when exposed to water, thereby achieving a waterproof effect.

[0082] The production method comprises the following steps:

[0083] The first step, warping:

[0084] Arrange the upper warp yarn Tupper and the lower warp yarn Tdown in sequence and warp them on one weaving beam.

[0085] Arrange the upper first pile warp R1 of the upper layer and the lower first pile warp R1 of the lower layer in sequence and warp them on one weaving beam.

[0086] Arrange the upper layer a pile warp upper R1-a and the lower layer a pile warp lower R1-a in sequence and warp them on one weaving beam.

[0087] Arrange the upper layer b pile warp R1-b and the lower layer b pile warp R1-b in sequence and warp them on one weaving beam.

[0088] Arrange the upper layer C pile warp upper R1-c and the lower layer C pile warp lower R1-c in sequence and warp them on one weaving beam.

[0089] Step 2: Drawing in the heddle and reed:

[0090] The upper warp yarn Tupper, the lower warp yarn Tdown, the upper first pile warp upper R1, the lower first pile warp lower R1, the upper a pile warp upper R1-a, the lower a pile warp lower R1-a, the upper b pile warp upper R1-b, the lower b pile warp lower R1-b, the upper c pile warp upper R1-c, the lower c pile warp lower R1-c, the middle layer A pile warp RA, and the middle layer B pile warp RB are threaded through the heddle in sequence and inserted into the same reed tooth.

[0091] The third step is to raise the harness, insert the weft and beat the weft:

[0092] A double-rapier loom is used and the weaving is carried out using the full-pile and half-pile weaving methods, including weaving the velvet door seam strip at the left end, weaving the velvet door seam strip in the middle and weaving the velvet door seam strip at the right end.

[0093] Furthermore, the double rapier loom used is the Belgian VSi double rapier loom, and its servo motor-controlled multi-arm velvet frame is flexible and changeable and easy to adjust, so that in full pile weaving, the upper rapier and the lower rapier can make the upper pile warp stacked and woven on the upper layer, and the lower rapier can make the lower pile warp stacked and woven on the lower layer.

[0127] The 29th shuttle: lift up the lower warp yarn T; lift up the upper layer a pile warp R1-a, the lower layer first pile warp R1, the lower layer b pile warp R1-b, and the lower layer c pile warp R1-c; sink the upper layer first pile warp R1, the upper layer b pile warp R1-b, the upper layer c pile warp R1-c, and the lower layer a pile warp R1-a; put the middle layer A pile warp RA and the middle layer B pile warp RB in the middle; put in the upper layer 29th weft yarn W29 and the lower layer 29th weft yarn W29, and beat the weft for weaving.

[0128] The 30th shuttle: lift up the lower warp yarn T; lift up the upper first pile warp R1, the lower a pile warp R1-a, the lower b pile warp R1-b, and the lower c pile warp R1-c; sink the upper a pile warp R1-a, the upper b pile warp R1-b, the upper c pile warp R1-c, and the lower first pile warp R1; put the middle A pile warp RA and the middle B pile warp RB in the middle; put in the 30th weft yarn W30 of the upper layer and the 30th weft yarn W30 of the lower layer, and beat the weft for weaving.

[0129] At this point, from the 19th shuttle to the 30th shuttle, the weaving of the right end of the velvet door seam strip is completed.

[0130] After the weaving of the left end RW, the middle ZH and the right end YO of the velvet door seam strip is completed, the next velvet door seam strip is cyclically weaved; there is a set distance between two adjacent door seam strips; the distance is formed by winding without lifting the weft.

[0131] Furthermore, the distance between two adjacent velvet door strips is 1.5 cm.

[0132] Step 4: Cutting the pile and finishing. During weaving, the cutting knife on the loom will cut the middle layer A pile warp RA and the middle layer B pile warp RB between the upper and lower base fabrics to form a pile blank, which is then finished.

[0133] The yarn lifting pattern during one cycle of weaving of velvet door seam strips is shown in Table 1.

[0134] Table 1 Yarn supply rules during a weaving cycle

[0135]

[0136]

[0137] In Table 1, × indicates that the upper warp yarn or the lower warp yarn is lifted up, ↓ indicates that the pile warp is sunk down, ↑ indicates that the pile warp is lifted up, and - indicates that the pile warp is located in the middle position.

[0138] In the weaving method of the velvet door seam strip, low-melting-point polyester yarn is used for the upper first weft yarn W1 to the upper twelfth weft yarn W12, the lower first weft yarn W1 to the lower twelfth weft yarn W12, the upper nineteenth weft yarn W19 to the upper thirtieth weft yarn W30, and the lower nineteenth weft yarn W19 to the lower thirtieth weft yarn W30. Therefore, after finishing, this part of the velvet warp and weft yarns can be more firmly consolidated.

[0139] Furthermore, since the middle layer A velvet warp RA and the middle layer B velvet warp RB are made of yarns that expand when exposed to water during the weaving process of the velvet door seam strip, if a fire occurs in the place of use, the door seam strip only needs to be sprayed with water, and the expanded pile will block the door seam, preventing smoke and flames from entering, and allowing time to wait for the arrival of rescue personnel.

[0140] Furthermore, the post-finishing includes at least one of insect-proofing treatment, mildew-proofing treatment, and antibacterial treatment.

[0141] This embodiment also involves a velvet door seam strip produced using a production method. The structure of this velvet door seam strip ensures that, despite being only approximately 1 cm thick, it still maintains a sufficiently dense pile and is firmly bonded and does not fall apart. This requirement cannot be achieved by other velvet strips cut from raw material. The resulting door seam strip n is secured to a door frame to close the gap between the door frame and the door m.

[0142] The door seam strip n, formed after cutting and trimming, includes the middle warp and weft base fabric TW of the velvet door seam strip, as well as the left and right end weft base fabrics RW, and a second pile R2 formed on one side thereof. This pile is formed by cutting the middle layer A pile warps RA and the middle layer B pile warps RB, and is located on the back of the door seam strip n. The door seam strip n also has a first pile R1, formed by cutting two adjacent door seam strips n apart, and located on the side of the door seam strip n. Specifically, it is formed by cutting the upper layer A pile warps R1-a, the upper layer B pile warps R1-b, the upper layer C pile warps R1-c, and the lower layer A pile warps R1-a, the lower layer B pile warps R1-b, and the lower layer C pile warps R1-c.

[0143] Therefore, because the velvet door seam strip and weaving method of the present invention are woven on a Belgian VSI velvet loom, because raw materials that swell when exposed to water are used, because a combined weaving method of full-raising and semi-raising is adopted, and because the weft yarn of the overlapping part is made of a low-melting-point raw material, the velvet door seam strip of the present invention can perfectly meet the needs of users and can also prevent smoke in special environments. Therefore, it is very popular in the market.

[0144] The above describes in detail the preferred embodiments of the present invention. It should be understood that those skilled in the art can make numerous modifications and variations based on the concepts of the present invention without inventive effort. Therefore, any technical solutions that can be derived by those skilled in the art through logical analysis, reasoning, or limited experimentation based on the concepts of the present invention and the prior art should be within the scope of protection defined by the claims.
