Production method of long-term soft and fluffy and hydroscopic and fast dry looped fabric

Abstract

The invention belongs to the technical field of textile production processes and particularly relates to a production method of long-term soft and fluffy and hydroscopic and fast dry looped fabric. The production method includes the steps of spinning, warping, sizing, weaving and dyeing and finishing treatment. During weaving, low-hot-water-shrinkage yarn and high-hot-water-shrinkage yarn are adopted as looped yarn, and weaving is carried out according to a specific yarn arrangement sequence. The looped fabric has the advantages of being soft after being washed multiple times and being hydroscopic and fast dry and low in hair, the drying time is 5 min or longer shorter than that of a towel of the same weight, and the pile retention is smaller than 0.5%. The limitation of raw material use is broken through, it is unnecessary to use superfine fiber yarn or superfine fiber filaments, and the product quality of the looped fabric can be remarkably improved. The product structure range to which the technical method is applicable is wider, and no double-hair structure is needed; the manufactured towel is better in style, and loops are smoother. A splitting process (dacron alkali peeling process) is not adopted, dyeing energy consumption is effectively reduced, and meanwhile environmental pollution caused by the splitting process is reduced.

Description

Technical field [0001] The invention belongs to the technical field of textile production technology, and in particular relates to a production method of long-lasting soft and fluffy, moisture-absorbing and quick-drying terry fabric. Background technique [0002] As a daily household item, towels usually use pure natural fiber yarn with excellent water absorption, comfortable and soft hand feeling as its main component. However, natural fiber yarn towels such as pure cotton towels have a hard feeling after washing, slow drying, and easy drying. Although the terry fabric with synthetic fiber as the main component does not have the above problems, it has problems such as poor water absorption and water storage, easy to snag, and easy to generate static electricity. In view of the above problems, the development of a terry fabric that combines the advantages of natural and synthetic fibers and avoids the shortcomings of the two is very suitable for the actual needs of consumers.

Problems solved by technology

From all kinds of towel invention patents disclosed at present, the technology of weaving and fluffing adjacent to natural fiber yarn and synthetic fiber yarn terry is described, such as a kind of terry fabric whose patent number is EP 2534987A1. This structure towel, the patent described is a synthetic fiber yarn (mainly filament) with a fineness of less than 0.6dtex and a natural fiber yarn through the above-mentioned way of yarn arrangement and then weaving and dyeing of a high and low wool structure. Towels, although the product described in the patent can indeed produce the characteristics of easy wetness, quick drying and long-lasting softness, there are many problems in the production process of weaving towels by this method, and the variety structure is also limited, such as fiber fineness less than 0.6dtex In the actual production process, the description actually locks that the yarn must be a filament, and it is a superfine fiber filament, and the current technical method to achieve a fiber fineness lower than 0.6dtex is mainly a sea-island structure synthetic filament. When this kind of filament and natural fiber yarn are weaved together, there are four problems: 1. The ultra-fine filament yarn must be a network filament with nodes, otherwise, it will be damaged during warping, sizing and weaving. It is very easy to have hairs in the middle, which seriously affects the weaving quality and driving efficiency; 2. Due to the large elastic elongation modulus of superfine fiber filament yarn and natural fiber yarn, the weaving process in the production process must adopt The method of wearing double wool with the same hedging and menopause is the double wool structure in the towel industry. Otherwise, the weaving will be hindered and the quality will be low due to the difference in tension between the two yarns; 3. Due to the network structure of the filament, it will cause dyeing. When the superfine fiber filaments are heated, the shrinkage rate of the fragments is different, which in turn affects the appearance of the product

4. High energy consumption and high pollution for dyeing: because it is ultra-fine fiber, and the fineness of single fiber is below 0.6dtex, most filaments need to be treated with fiber opening (alkali weight reduction), and fiber opening (alkali weight reduction process) not only Increase the weight loss rate of the product. At the same time, a large amount of lye will be used for fiber opening, which will cause serious environmental pollution. After fiber opening, the fiber fineness is too fine. Although the product softness is improved, the product bulkiness is not good.
