Description

Technical Field

[0001] The invention belongs to the field of manufacturing technology and relates to a preparation method of a wool knitted fabric and a product and application thereof. Background Art

[0002] In the field of textile fabrics, with the improvement of people's quality of life and the diversification of lifestyles, the requirements for fabric performance are becoming increasingly diversified. Lightweight, hydrophilic, and quick-drying fabrics have shown significant advantages in many application scenarios and have become a hot topic in current research and development.

[0003] In recent years, leisure activities such as fitness and outdoor sports have become increasingly popular. During exercise, the human body produces a large amount of sweat. Traditional fabrics that fail to absorb moisture and dry quickly can cause the wearer to feel hot and humid, which not only affects the exercise experience but can also lead to health problems such as colds. Lightweight, hydrophilic, and quick-drying fabrics can quickly absorb sweat and evaporate it quickly, keeping the skin dry and comfortable, providing athletes with a comfortable wearing experience and meeting their demand for functional sports equipment.

[0004] It's difficult to balance lightness with hydrophilicity and quick-drying properties: Some lightweight fabrics, while somewhat breathable, lack both hydrophilicity and quick-drying properties. These fabrics often have a loose fiber structure, allowing moisture to easily slide off the surface rather than being effectively absorbed and quickly transferred to the surface for evaporation. Conversely, some fabrics with high hydrophilicity often utilize thicker materials or specialized structures to increase moisture absorption, resulting in a heavier fabric that loses its lightweight properties and can be quite stuffy.

[0005] In view of the above-mentioned deficiencies in the existing technology, it is of great practical significance to develop a fabric that can maintain its light and thin characteristics, has excellent hydrophilic and quick-drying properties, good durability and controllable cost. Summary of the Invention

[0006] In view of the deficiencies in the prior art, the present invention aims to provide a method for preparing a wool knitted fabric, and its product and application.

[0007] In order to achieve the purpose of the invention, the present invention adopts the following technical solutions:

[0008] In a first aspect, the present invention provides a method for preparing a wool knitted fabric, the method comprising:

[0009] (1) mixing shrink-resistant wool, nylon and Coolmax fibers, spinning and weaving to obtain grey fabric;

[0010] (2) dyeing, dehydrating, drying, cutting and shaping the grey cloth;

[0011] The dyeing process also includes mixing with SR-100T.

[0012] The present invention prepares a grey fabric that has a light and thin feel while having high bursting strength through the selection of ingredients. The addition of Coolmax fiber, SR-100T, and RB-854N enhances the quick-drying effect of the fabric, making it less likely to burst while having a light and thin feel, and is beneficial to the stability of the fabric size.

[0013] Preferably, the mass ratio of the shrink-resistant wool, nylon and Coolmax fiber is (50-65):(12-32):(16-38).

[0014] The specific point values in (50-65) can be selected from 50, 52, 54, 56, 58, 60, 62, 65, etc. The specific point values in (12-32) can be selected from 12, 15, 18, 20, 22, 24, 26, 28, 30, 32, etc. The specific point values in (16-38) can be selected from 16, 18, 20, 23, 25, 27, 30, 33, 35, 38, etc. Other specific point values within the above numerical range can be selected, so they will not be listed here one by one.

[0015] Preferably, the addition amount of the SR-100T is 1-6wt%, for example, 1wt%, 1.5wt%, 2wt%, 2.5wt%, 3wt%, 3.5wt%, 4wt%, 4.5wt%, 5wt%, 5.5wt%, 6wt%, etc. Other specific point values within the above numerical range can be selected and will not be repeated here.

[0018] Preferably, the padding pressure is 65-75N and the padding time is 1-3 minutes.

[0019] The pressure can be selected as 65N, 66N, 67N, 68N, 69N, 70N, 71N, 72N, 73N, 74N, 75N, etc., and the time can be selected as 1min, 1.2min, 1.5min, 1.8min, 2min, 2.2min, 2.5min, 2.8min, 3min, etc. Other specific point values within the above numerical range can be selected, so they will not be listed here one by one.

[0020] Preferably, the mixing temperature with SR-100T is 106-120° C. and the mixing time is 45-60 min.

[0021] The temperature can be selected as 106℃, 108℃, 110℃, 112℃, 114℃, 116℃, 118℃, 120℃, etc., and the time can be selected as 45min, 48min, 50min, 52min, 55min, 58min, 60min, etc. Other specific point values within the above numerical range can be selected, so they will not be listed here.

[0022] SR-100T and RB-854N are both hydrophilic quick-drying agents. The addition of SR-100T and RB-854N can further enhance the hydrophilic quick-drying effect of the fabric, and SR-100T and RB-854N have a certain synergistic effect.

[0023] Preferably, the opening method is oblique opening.

[0024] Preferably, the slant opening value of the slant opening width is 2-15%, for example, 2%, 3%, 4%, 5%, 6%, 7%, 8%, 9%, 10%, 11%, 12%, 13%, 14%, 15%, etc. Other specific point values within the above numerical range can be selected, and they will not be repeated here.

[0025] In a second aspect, the present invention provides a wool knitted fabric prepared according to the method for preparing the wool knitted fabric according to the first aspect.

[0026] Preferably, the gram weight of the wool knitted fabric is 74-80gsm, such as 74gsm, 75gsm, 76gsm, 77gsm, 78gsm, 79gsm, 80gsm, etc. Other specific point values within the above numerical range can be selected, and they will not be described here one by one.

[0066] Test Example 1

[0067] Bursting strength

[0068] Test method: Refer to GB / T 7742.2.

[0069] Table 1

[0070]

[0071]

[0072] It can be seen from the data in Table 1 that the fabric prepared by the present invention has a high bursting strength, is qualified in bursting, and meets the requirements of national standards. The fabric of the present invention is light and thin while ensuring strength.

[0073] Test Example 2

[0074] Dimensional change after washing

[0075] Test method: Refer to GB / T8629,4N.

[0076] Table 2

[0077]

[0078] It can be seen from the data in Table 2 that the dimensional change rate after washing of the present invention meets the requirements of the national standard, the dimensional change rate after washing is small, and the addition of Coolmax fiber is conducive to reducing the dimensional change rate after washing.

[0079] Test Example 3

[0080] Hydrophilic and quick-drying

[0081] Test method: GB / T 21655.1, test results before washing and 4N, after washing 5 times.

[0082] Table 3

[0083]

[0084]

[0085] The data in Table 3 show that the fabric prepared by the present invention has a short drip diffusion time and a fast drying rate, meeting requirements both before and after washing. RB-854N and SR-100T have a certain synergistic effect in improving drying rate and drip diffusion time. Without either, the drying rate will decrease and fail to meet the standard (the national standard stipulates a drying rate of 0.2 g / h before and after washing). The addition method of RB-854N and SR-100T is crucial for the drying rate.
