Description

Technical Field

[0001] The present invention belongs to the technical field of bath towels, and particularly relates to a method for preparing Lyocell bath towel fabric and an environmentally friendly bath towel. Background Art

[0002] Lyocell is a kind of man-made cellulose fiber, belonging to a kind of regenerated fiber, similar to viscose fiber, but with a more environmentally friendly production process. Lyocell fiber is made from wood pulp, and the raw material is usually sustainable wood such as eucalyptus. The manufacturing process uses NMMO solvent, which can be recycled, so it has good environmental performance. Its characteristics such as moisture absorption and breathability, softness and skin-friendliness, high strength, wrinkle resistance and degradability are all the advantages of Lyocell. Moreover, compared with viscose fiber, the production process of Lyocell fiber is more environmentally friendly and has better performance.

[0003] However, due to practical reasons such as insufficient frictional force, there is no precedent for using Lyocell to make bath towels at present. This application aims to solve the problem of applying Lyocell fiber to bath towels. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a method for preparing Lyocell bath towel fabric and an environmentally friendly bath towel in view of the deficiencies of the prior art, to improve the durability and environmental friendliness of the bath towel, and to avoid the possible irritation caused by traditional rough bath towels.

[0026] Embodiment 1:

[0027] As Figure 1 shown, it is a process flow diagram of the preparation method of the Lyocell bath towel fabric provided by this application, including the following steps:

[0028] S1. Twist the Lyocell Z-direction yarn and the Lyocell S-direction yarn on a doubling twister to 1350 - 1450 turns per meter. In this embodiment, both the Lyocell Z-direction yarn and the Lyocell S-direction yarn are made of 16-count Lyocell monofilaments. The doubling twister is a 310 doubling twister. Generally, the twisting strength of Lyocell yarn is 400 - 1000 turns per meter. Since it is lower than 1000 turns per meter, the shrinkage resistance of the Lyocell yarn is not good, the wrinkles generated are not good, and the use effect of the bath towel cannot be achieved. In this application, the twist is increased to 1350 - 1450 turns per meter by a 310 doubling twister, which is exactly at the critical point of the yarn strength, achieving the water absorption and wrinkle effect of the bath towel. Among them, the Lyocell Z-direction yarn is twisted to 1450 turns per meter, and the Lyocell S-direction yarn is twisted to 1350 turns per meter.

[0029] During preparation, 16 Lyocell Z-direction yarns are first wound on aluminum straight tubes, then placed on a 310-fold twister for deep twisting to 1450 twists, and wound onto aluminum triplets. For 16 Lyocell S-direction yarns, they are first wound on aluminum straight tubes, then placed on a 310-fold twister for deep twisting to 1350 twists, and wound onto aluminum triplets.

[0030] S2. Then, the twisted Lyocell Z-direction yarns and Lyocell S-direction yarns are heated in a steaming box and dried after heating. In this embodiment, the Lyocell Z-direction yarns and Lyocell S-direction yarns are heated in a 100-degree steaming box for 180 minutes. After heating, the steaming box is quickly opened to let the internal hot air volatilize, so that the Lyocell yarns cool down and dry thoroughly.

[0031] S3. Use 120D or 150D viscose rayon as the radial yarns, and the dried Lyocell Z-direction yarns and Lyocell S-direction yarns as the weft yarns. The radial yarns and weft yarns are interwoven to make bath towel fabrics. During preparation, on a rapier loom, it is woven according to the production processes of 5Z and 5S, or 4Z and 4S, or 3Z and 3S to produce flat fabrics.

[0032] The bath towel fabrics are stirred in hot water above 60 degrees for 2 - 3 minutes to retract the wrinkles on the fabric surface. The produced grey fabrics are required to be washed in hot water above 60 degrees. The higher the water temperature, the faster the fabric wrinkles retract, saving time, usually 2 - 3 minutes. The grey fabrics are put into an industrial washing machine and stirred in hot water for 2 - 3 minutes, preferably about 2 pieces each time.

[0033] Finally, the bath towel fabrics also go through the processes of dyeing, washing, color fixing, dehydration, drying, and shaping in sequence. The shaping shrinkage rate is generally controlled at 18 - 20%, achieving the effect of plump wrinkles and uniform particles.

[0034] The bath towel fabrics prepared by the preparation method of this application have better moisture absorption than cotton, can quickly absorb and volatilize water, and are suitable for cleaning products in contact with the skin; the Lyocell fibers have a smooth and delicate surface, are friendly to the skin, are suitable for people with sensitive skin, avoiding the possible irritation caused by traditional rough bath towels. The Lyocell fibers can balance cleaning power and mildness. Compared with viscose fibers, the production process is more environmentally friendly and the performance is more excellent.

[0035] Example 2:

[0036] This application provides an environmentally friendly bath towel made of the above bath towel fabrics, which solves the problem of insufficient friction of Lyocell fibers, improves the durability of the bath towel and its environmental protection characteristics, realizes the function of zonal cleaning, adapts to the needs of different skin types, and has a more comfortable use experience.

[0037] When making the bath towel, the Lyocell bath towel fabric is laminated with the terry cloth, which is convenient for later cutting and sewing. Cut it according to the market requirements of 15 cm in width and 42 cm in length, and then edge it on the edge sewing machine to make it in the shape of a glove.

[0038] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
