Description

Technical Field

[0001] The invention relates to the technical field of elastic thread preparation, in particular to a fine-denier porous super-soft bamboo elastic thread and a preparation method thereof. Background Art

[0002] Bamboo silk, as the name implies, is a kind of fabric made of filament fibers through a manufacturing process. The applicable filaments include chemical fiber filaments, natural filaments such as silk (mulberry silk), milk silk, soybean silk and other fine denier silks; Bamboo silk processed by special technology is shiny and soft in its dry state. It has the skin-friendly characteristics of silk. When the twist changes (the thickness or length of the bamboo joints changes), it contrasts with the change in the twist of the bamboo joint spacing.

[0003] The fine denier fiber is classified into 1.0-2.4dpf as fine denier fiber, 0.3-1.0dpf as ultrafine fiber, and 0-0.3dpf as superfine fiber.

[0004] There are several problems in the preparation process of elastic silk threads in the prior art. First, the efficiency of dyeing the silk threads individually during the yarn making process is relatively slow, and the threads need to be twisted and wound again after being dyed. When dyeing is performed again after twisting and winding, the dyeing inside and outside will be uneven, thus affecting the appearance of the fabric. At the same time, the twisting and winding of multiple groups of elastic silk threads will become loose due to the combination of multiple threads, thus affecting the twisting and winding effect. Based on the above problems, there are preparation defects.

[0005] When applying for the present invention, the applicant found through searching that a Chinese patent disclosed a "T / R elastic super soft air knitted fabric and its preparation method", and its application number is "201711478673.8". The patent mainly prepares T / R elastic super soft air knitted fabric, the cloth surface, air layer and base fabric are all made of polyester material, which has the characteristics of soft hand feeling, light weight, good drape, strong warmth retention performance, and permanent elasticity. At the same time, this kind of fabric can overcome the shortcomings of pilling and reach the national standard of D method ≥3 level; in the production process of this kind of T / R elastic super soft air knitted fabric, select The unique raw material and weaving method of T / R colored yarn covered with spandex are selected. There is no need for dyeing in the post-processing process of the grey cloth. The T / R elastic super soft air knitted fabric can be obtained through a low-temperature setting process. The low-temperature setting temperature is 90-100°C. It saves a lot of production costs, improves factory efficiency, and reduces the impact on the environment. It has huge market prospects and social benefits. However, there are still problems of low dye efficiency and loose twisting and winding in the preparation process of the elastic silk thread. Therefore, according to the applicant's invention, a fine denier porous super soft bamboo elastic yarn is invented, which solves the problems of uneven dyeing and loose twisting and winding.

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] Embodiment 1:

[0039] like Figure 1-4 As shown, the embodiment of the present invention provides a fine-denier porous super-soft bamboo elastic yarn, including: a first elastic yarn 1, a second elastic yarn 8 and a third elastic yarn 9, the first elastic yarn 1, the second elastic yarn 8 and the third elastic yarn 9 are all of the same structure and material, through this structure, multiple groups of the same elastic yarns can be wound together to form a firm elastic yarn, the first elastic yarn 1, the second elastic yarn 8 and the third elastic yarn 9 are fixedly connected with a wear-resistant layer 2 on the inside, and the wear-resistant effect is provided by adding the wear-resistant layer 2, and it is not easy to cause damage, and a fine-denier porous layer 7 is arranged on the inside of the wear-resistant layer 2, and the fine-denier porous layer 7 has a high air permeability and hygroscopicity by adding a large number of pore structures inside the fiber. Compared with traditional synthetic fiber materials, fine-denier porous nylon has better air permeability, can effectively reduce the stuffiness during exercise, and make the skin more comfortable. In addition, fine-denier porous nylon also has the advantages of being light, soft, and wear-resistant, and is a very excellent sports material;

[0040] The upper surface of the fine-denier porous layer 7 is fixedly connected with a plurality of elastic tendons 3, which provide an elastic stretching effect through the elastic tendons 3, and the elastic effect is better. The bottom end of the fine-denier porous layer 7 is provided with an antibacterial layer 4, and the antibacterial effect is increased through the antibacterial layer 4. The bottom end of the antibacterial layer 4 is fixedly connected with a plurality of spacer strips 6. The inner sides of the first elastic thread 1, the second elastic thread 8 and the third elastic thread 9 are all provided with spacer strips 6 to increase the thread gap and improve the air permeability effect. The fabric prepared by the elastic thread can have a better air permeability effect, and the practicality of the conventional air permeable layer is better than that of the conventional air permeable layer. Stronger, the surface of the antibacterial layer 4 and the spacer strip 6 is coated with a glue bonding layer 5. Through the setting of the glue bonding layer 5, the multiple groups of elastic threads are not easy to loosen during the twisting and winding process, and the two ends of the elastic threads and the end positions provide a stronger bonding effect. The winding center of the first elastic thread 1, the second elastic thread 8 and the third elastic thread 9 is provided with an absorbent cotton layer 10. The absorbent cotton layer 10 increases the absorption of liquid, plays an important role in the dyeing process, and can also have a sweat-absorbing effect during actual use, thereby increasing the comfort of use.

[0041] The glue coating length of the glue bonding layer 5 is 5cm. By setting it to 5cm, the waste of resources can be reduced. It is only necessary to ensure that the end is not easy to loose. At the same time, when there is more glue liquid, it will affect the use effect. The glue bonding layer 5 is distributed at both ends of the first elastic thread 1, the second elastic thread 8 and the third elastic thread 9. The diameter of the elastic rib 3 is 2-5mm. The elastic rib 3 increases the elastic support effect and provides elastic tension. The diameter of the elastic rib 3 is small, but the tension is better when used in combination with multiple ribs. The diameter of the spacer 6 is 3-5mm. By setting the spacer 6 in combination with the fine denier porous layer 7, a better breathability effect is provided.

[0042] A method for preparing fine-denier porous ultra-soft bamboo stretch yarn comprises the following specific steps:

[0043] Step 1: Making the Yarn

[0044] The elastic threads are prepared with a diameter of 5-10 mm respectively, and the elastic threads are yarned into multiple groups of fine yarn structures to facilitate subsequent twisting and winding to prepare high-strength elastic threads;

[0045] Step 2: Gluing

[0046] The ends of the first elastic thread 1, the second elastic thread 8 and the third elastic thread 9 are coated with a glue bonding layer 5. The glue bonding layer 5 can provide adhesive fixation during the twisting and winding process, and provide adhesive fixation for multiple groups of elastic threads. The threads are not easy to loosen during the twisting and winding process, and are convenient for subsequent use and are not easy to split. By adding this step in the preparation process of the elastic threads, the looseness and splitting of the combination of multiple groups of elastic threads are effectively reduced, which seriously affects the efficiency of the twisting and winding.

[0047] Step 3: Wrap

[0048] The first elastic thread 1, the second elastic thread 8 and the third elastic thread 9 are twisted and wound, and during the winding process, the forward twisting winding needs to be completed around the central absorbent cotton layer 10, and the use strength is increased by using multiple groups of the first elastic thread 1, the second elastic thread 8 and the third elastic thread 9;

[0049] Step 4: Dye

[0050] The twisted and wound elastic thread is mixed with the dye, and the absorbent cotton layer 10 absorbs the liquid during the mixing process. The absorbent cotton layer 10 absorbs the liquid of the dye, and squeezes it again after absorption to disperse the liquid outward, thereby squeezing the inner walls of the first elastic thread 1, the second elastic thread 8, and the third elastic thread 9 to fill the dye, thereby increasing the uniformity of the dye. At the same time, the absorbent cotton layer 10 can also absorb the sweat generated by the body during actual use, and has a good sweat absorption effect, thereby increasing the comfort of use.

[0051] Step 5: Extrusion

[0052] By squeezing the elastic thread, the absorbed liquid of the absorbent cotton layer 10 is diffused to the outer circumference, providing re-dyeing for the dye wound inside the elastic thread, completing the uniform dyeing effect on the surface and the inside, and by squeezing the dye, the dye liquid is discharged from the inside to the outside, and the dyeing effect is better;

[0053] Step 6: Drying

[0054] The prepared first elastic thread 1, the second elastic thread 8 and the third elastic thread 9 are dried and put into use. By drying the elastic threads, the elastic threads are convenient for storage, transportation and weaving.

[0055] In step 4, the dyeing time is 10-20 minutes. The dyeing time of 10-20 minutes can increase the contact between the surface and the dye. In step 6, the drying temperature is 30-40°C. The drying temperature of 30-40°C increases the drying and is not easy to affect the use of the elastic filaments. The drying time is 15-20 minutes. The drying time is 15-20 minutes. By controlling the drying temperature and time, the internal dye humidity of multiple groups of first elastic threads 1, second elastic threads 8 and third elastic threads 9 is fully dried.

[0056] Comparative Example:

[0057] The difference between this embodiment and the first embodiment is that:

[0058] A method for preparing fine-denier porous ultra-soft bamboo stretch yarn comprises the following specific steps:

[0059] Step 1: Making the Yarn

[0060] The elastic threads are prepared with a diameter of 5-10 mm respectively, and the elastic threads are yarned into multiple groups of fine yarn structures to facilitate subsequent twisting and winding to prepare high-strength elastic threads;

[0061] Step 2: Dye

[0062] Dyeing the plurality of first elastic threads 1, second elastic threads 8 and third elastic threads 9 to increase the surface uniform dyeing effect, and dyeing the plurality of elastic threads requires multiple steps;

[0063] Step 3: Wrap

[0064] The first elastic thread 1, the second elastic thread 8 and the third elastic thread 9 are twisted and wound, and the use strength is increased by using multiple groups of the first elastic thread 1, the second elastic thread 8 and the third elastic thread 9;

[0065] Step 4: Drying

[0066] The prepared first elastic thread 1, the second elastic thread 8 and the third elastic thread 9 are dried and put into use. By drying the elastic threads, the elastic threads are convenient for storage, transportation and weaving.

[0067] The fine-denier porous super-soft bamboo stretch yarn prepared in Example 1 and the comparative example were used respectively, and the preparation conditions were recorded. The results are shown in Table 1:

[0068] Table 1

[0069]

[0070] It can be seen from Table 1 that the different steps of gluing, winding, dyeing and extrusion are added in Example 1 and the comparative example, which improves the preparation efficiency of the elastic yarn, makes it less likely to loosen, improves the dyeing efficiency and makes the dyeing more fully and evenly distributed, thereby improving the textile production efficiency.
