AI Technical Summary
Existing mattress spring pockets made of polyester material suffer from problems such as being thin, having poor adhesion, being prone to cracking after prolonged spring stretching, and not being quiet.
Fabrics woven from polyester and cotton-linen fibers are stitched together using ultrasonic waves or hot melt adhesive to form seams, which enhances bonding strength, reduces friction noise, and improves breathability.
The fabric bag is made of durable and soft material, not easy to crack, quiet and breathable, which improves the lifespan and comfort of the mattress.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of mattress spring production technology, specifically a woven fiberized mixed cotton and linen mattress spring bag. Background Technology
[0002] Mattress spring pockets are made by covering the surface of the springs with a cloth bag and then ultrasonically sewing them together to form a pocket spring strip. The pocket springs are then connected together with hot melt adhesive or ultrasonic sewing to form the mattress spring layer. Current spring pockets are generally made of non-woven fabric and PVC (which will turn into dust over time).
[0003] A search of patent number CN202420818290.X reveals a mattress spring bag comprising: an outer spring covering body fitted over the surface of several springs; and sewing connection points arranged in a straight line to form a seam. The mattress spring bag assembly uses ultrasonic waves to sew along these connection points. The outer spring covering body is made of woven synthetic fiber fabric. This woven synthetic fiber fabric spring bag, with the same production efficiency, is more durable, does not powder, has better breathability, and is quieter; it effectively solves the problems of non-woven and synthetic fabric spring bags being not durable, prone to powdering, and not breathable. The woven synthetic fiber fabric can be sewn together using ultrasonic waves or hot melt adhesive, and can be produced using mattress spring bag assembly equipment, improving production efficiency; it effectively solves the problem that cotton and linen spring bags can only be sewn manually, making them unsuitable for production using mattress spring bag assembly equipment and for ultrasonic or hot melt adhesive sewing.
[0004] The woven fiber fabric mentioned above is mainly made of polyester. Polyester is thin, has poor adhesion, is prone to cracking and is not durable after prolonged spring stretching, and also has problems such as noise from friction. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a woven fiber-modified cotton-linen mattress spring bag, which solves the problems of polyester being thin and having poor adhesion, springs being prone to cracking and not durable after prolonged stretching, and also causing friction noise.
[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a woven fiber-reinforced mixed cotton and linen mattress spring bag, comprising a spring bag and a spring; The spring bag is fitted onto the surface of the spring; The spring bag has sewing connection points on its front and sides, and the sewing connection points form a sewing line by being arranged in a straight line.
[0007] Preferably, the spring bag is made of a fabric woven from polyester fibers and cotton and linen fibers.
[0008] This invention provides a woven fiber-reinforced cotton-linen blend mattress spring pocket. Compared with the prior art, it has the following advantages: The woven fiber-blended cotton-linen mattress spring bag is made of a fabric woven from polyester fiber and cotton-linen fiber. The polyester fiber has strong adhesion, which provides adhesive strength and ensures that the stitching is firm and does not come undone when using ultrasonic or hot melt glue. The cotton-linen fiber has high softness and thickness, does not produce friction noise, and has good breathability. It achieves good toughness, high softness, no cracking, and strong adhesion, thus achieving the effect of quietness and high breathability. Attached Figure Description
[0009] Figure 1 This is a schematic diagram of the structure of this utility model; Figure 2 This is a cross-sectional view of the structure of this utility model.
[0010] In the picture: 1. Spring bag; 2. Seam connection point; 3. Spring. Detailed Implementation
[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0012] Please see Figures 1-2 This utility model provides a technical solution: a woven fiber-modified mixed cotton and linen mattress spring bag, including a spring bag 1 and a spring 3. The spring bag 1 is sleeved on the surface of the spring 3. The front and side of the spring bag 1 are provided with sewing connection points 2, and the sewing connection points 2 form a sewing line by being arranged in a straight line. The mattress spring bag can be sewn together using ultrasonic waves or hot melt adhesive.
[0013] The spring bag 1 is made of a fabric woven from polyester fiber and cotton linen fiber. The polyester fiber has strong adhesion, providing bonding strength to ensure that the stitching is firm and does not come undone when using ultrasonic or hot melt adhesive. The cotton linen fiber is soft and thick, does not produce friction noise, and has good breathability.
[0014] Therefore, the spring bag 1 achieves good toughness, high flexibility, no cracking, and strong adhesion, and also achieves the effects of quietness and strong breathability with the spring 3. Example
[0015] Material preparation: The blend of 60% cotton and linen fibers (linen + cotton) and 40% polyester fibers is interwoven on a loom with a warp density of ≥120 yarns / inch and a weft density of ≥80 yarns / inch.
[0016] The fabric surface undergoes a fiberization treatment: mechanical napping forms a 0.1~0.3mm micro-fleece layer.
[0017] Sewing process: Cut the fabric into rectangular dimensions to fit a spring with a diameter of 3. The mattress spring pocket device uses ultrasound or hot melt adhesive to sew the connection through the suture line formed at the suture connection point 2.
[0018] Performance verification: Noise level test: After the spring 3 was repeatedly compressed 100,000 times, the noise level remained stable at 18~22dB; Breathability test: Breathability reaches 320L / m²·s; Strength test: Tensile strength 52N.
[0019] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, the phrase "comprising an element defined as..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
