Textile internally provided with ultra-thin cotton quilt and preparation method

Abstract

The invention relates to the field of cotton product production, and particularly discloses a textile internally provided with ultra-thin cotton quilt and a preparation method of the textile. The textile comprises upper fabric and lower fabric, the ultra-thin cotton quilt is filled into the portion between the upper fabric and the lower fabric, the content of ginned cotton in the ultra-thin cotton quilt is 100 percent, the length of the ultra-thin cotton quilt ranges from 3 m to 6 m, the thickness ranges from 0.7 cm to 2.6 cm, and the unit area weight ranges from 0.15 kg / m<2> to 0.45 kg / m<2>. The preparation method of the textile comprises the steps of dehydration, cotton ginning, opening and scutching, impurity removing, carding, coiling, cotton kneading and shaping and fabric sewing, wherein in the cotton kneading and shaping process, the distance between a connecting shaft on a kneading plate of a cotton kneading machine and the central axis of a rotational motion shaft needs to be maintained to range from 10 mm to 15 mm. According to the textile internally provided with the ultra-thin cotton quilt and the preparation method of the textile, the processing technology is simple, the production efficiency is high, the prepared textile is thin in thickness, light in unit area weight, and the preparation method can be suitable for warmth-keeping products such as winter clothes and blankets.

Problems solved by technology

[0002] In the prior art, the built-in fillings of textiles such as light and beautiful winter clothing and blankets tend to be lighter and thinner down and chemical fiber cotton. However, down has been relatively expensive for a long time and is not easily used. The general public accepts that although the price of chemical cotton is cheap, due to its poor air permeability, it is easy to cause rheumatism after long-term wearing. In addition, in industrial production, the anti-static effect of clothing with built-in chemical cotton is also poor. For some special industries (such as the power industry) staff have a risk of leakage

[0003] Cotton batts have better warmth retention and air permeability, and are cheap, but due to the limitations of existing equipment and processes, the current finished cotton batts are often "thicker". It is used to prepare bedding such as cotton quilts and cotton mattresses. Although there are some clothing products with built-in cotton tires on the market, the production method is often to manually cut the cotton wool into small cotton pieces for filling and sewing. In the process, it is very easy to have uneven filling, and even defective products. At the same time, this method has low production efficiency and high production costs, and it is difficult to carry out mass industrial production.

[0004] In addition, in terms of the traditional cotton batt production process, the current manufacturers generally select a certain weight of lint cotton according to the cotton batt specification (weight) customized by the customer, put it into the popping machine for processing into lint, and then pass it through the rolling machine. Cotton tube rolls the lint into a primary billet roll. The circumference and length of the cotton drum are the same as the length and width specifications of the custom-made cotton batt. When the finished cotton tire is processed, the primary billet roll needs to be cut from it, and then flattened. Lay it into the kneading machine for kneading and pressing processing. Therefore, when customizing cotton tires of different specifications, it is inefficient and lacks flexibility

[0005] In terms of kneading and pressing processing by the kneading machine, in the prior art, the weight per unit area of ​​the finished cotton tire that can be kneaded and pressed by the kneading machine is generally 0.5kg / m 2 As mentioned above, when the unit area of ​​the finished cotton batt is lower than this weight, due to the limitation of the structure of the traditional kneading machine (large eccentricity, generally 30-35mm), the cotton batt is prone to "clustering" during kneading and pressing phenomenon, it is difficult to meet the production demand

In addition, due to the thick cotton batt processed by the existing kneading machine, it often takes more than ten minutes to process the primary billet to the finished cotton batt, and the production efficiency is also low
