Detailed Description

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

With the development of society, people's demand for the fabric of clothes has not satisfied simply shielding the body, has also put forward higher requirements to the travelling comfort and the environmental protection performance of fabric. For this reason, in the textile field, natural materials are increasingly used for making fabrics to provide a more comfortable experience for the user and also to meet the increasingly stringent requirements of environmental protection. However, while providing comfort and environmental protection, natural fabrics have a major drawback in terms of functionality, i.e., cannot provide more functionality.

Tencel, as a regenerated cellulose fiber, is prepared by making wood into wood pulp, then adopting the spinning process of NMMO for example, and dissolving the wood pulp in an ammonium oxide solvent for spinning, the whole process can be completely completed under the physical action, the used ammonium oxide solvent can be recycled, and the actual solvent recovery rate can be up to more than 99 percent, so that the whole preparation process of the Tencel fiber is non-toxic, pollution-free, and biochemically degradable, and does not cause pollution to the environment.

In the case of using tencel fiber for a fabric, it is common to utilize the somatosensory properties of its soft feeling and drape feeling, and therefore it is common to use it as a single layer, having moisture absorption and air permeability of natural plant fiber, but not having a waterproof function. However, for users, it is often desirable to purchase fabrics that provide a soft and comfortable body feel while also having the functionality of being waterproof, e.g., rain-proof.

For this reason, in the prior art, a waterproof material, for example, a waterproof aid, is usually added to the tencel fiber when the tencel fiber is manufactured, so that after the tencel fiber is manufactured and shaped, the surface of the tencel fiber is coated with such a waterproof material to make the whole waterproof function. However, since the thickness of the tencel fiber in practical use is usually very thin, for example, only a single layer of tencel fiber is used, in the prior art, a small amount of waterproof material may be added to the tencel fiber in order not to affect the softness and drape of the manufactured tencel fiber, so that when the waterproof material is dried and fixed on the surface of the tencel fiber, the influence on the softness of the tencel fiber itself is small, but in such a scheme, the amount of the waterproof material added is limited, so that the coverage on the surface of the tencel fiber is actually insufficient, the concentration of the waterproof material in the final tencel fabric is insufficient, and a good waterproof effect is difficult to achieve. On the contrary, in the prior art, in order to enhance the waterproof effect of the tencel fiber, a large amount of waterproof materials are added on the surface of the tencel fiber, so that the surface of the tencel fiber can be fully covered after the waterproof materials are dried, and the waterproof effect of the fabric is ensured. However, in this case, since a large amount of waterproof material is coated on the surface of the tencel fiber, the flexibility and drapability of the tencel fiber are greatly affected by the dry waterproof material with high hardness, and if a user wears the tencel fiber fabric, the tencel fiber fabric has a hard hand feeling, which seriously affects the wearing experience of the user.

To this end, as shown in fig. 1, an embodiment of the present application provides a tencel fiber with waterproof and vapor-permeable functions, which may include: a tencel fiber layer 1, an adhesive layer 2, a waterproof layer 3 and a film layer 4.

The tencel fiber layer 1 may be composed of different warp and weft weaves. For example, in the preparation, tencel raw material may be warped in batches using a warping machine, in the warping process, the linear velocity may be 400 to 600m/min, preferably 500m/min, and after the warping is completed, the warp beam may be sized, the sizing may be starch sizing, and the sizing rate may be 6 to 10%, preferably 8%. After sizing, a drafting and reed treatment may be performed, and then weaving may be performed using, for example, a rapier loom, so that warp and weft yarns are woven on the loom to be processed into a fabric of a different texture.

For example, the weaving speed can be 450-480r/min and the efficiency can be 95-97% in the weaving process. Particularly, the tension of the rapier loom can be controlled to be uniform in the weaving process, so that the problem of edge difference caused by the tension of the grey cloth is avoided.

In addition, after the weaving process, in order to ensure the smoothness of the surface of the fabric in the process, the open width device can be used for jig dyeing, so that the treated fabric is not easy to generate wrinkle marks. In the dyeing treatment of the Tencel fiber, a reactive dye may be used as the dye, and Tencel fiber dyeing is performed at a temperature of 50 ℃ to 70 ℃. The dye may be added in two portions throughout the dyeing process, for example, 60% of the dye may be added first at the beginning of the dyeing process and the remaining 40% of the dye may be added at the end of the first pass.

The dyeing treatment can be further followed by a fixation treatment. For example, soda ash may be used as the primary fixing alkaline agent, and the pH may be maintained at 10-11. After color fixing treatment, water washing treatment and soap boiling can be carried out to remove loose color and hydrolytic dye and improve the color brilliance and dyeing fastness. Preferably, in the dyeing treatment, the temperature can be increased to the dyeing temperature at a speed of 0.5-2 ℃/min, because if the temperature is increased too fast, the finally prepared fabric is uneven in dyeing, insufficient in fastness and too crisp in cloth surface. After the fixing process, the tencel fiber may be subjected to a dehydration and drying process, so that the tencel fiber layer 1 may be obtained.

The waterproof layer 3 may be adhered on one side surface of the tencel fiber layer 1. In the embodiment of the present application, the waterproof layer 3 only needs to be applied to one side surface of the tencel fiber layer 1, and therefore, the amount of the waterproof auxiliary agent can be controlled to a low degree, so that the tencel fiber added with the waterproof layer 3 according to the embodiment of the present application can maintain good softness and drape after padding and sizing treatment.

The adhesive layer 2 is covered on the other side surface of the tencel fiber layer 1, and the film layer 4 may be attached on the outer side surface of the adhesive layer 2 away from the tencel fiber layer 1. For example, in the embodiment of the present application, bio-based PU Gao Toumo can be used as the film layer 4, and the high performance index of 10K is used for moisture permeation by using a water pressure of 10K, so that the film layer 4 attached on the adhesive layer 2 can have the functions of water repellency, vapor permeability, water resistance and wind resistance. In addition, the membrane can be degraded by about 30% in five years under industrial composting conditions. In the laminating process, a 1600-mesh diamond stick can be used, fule high moisture-permeable glue is adopted, the laminating pressure is adjusted to 4-5 kg, and the whole laminating process adopts tension-free winding up for laminating.

The embodiment of the utility model provides a functional tencel fibre, provide waterproof performance through a side surface adhesion waterproof layer at tencel fibrous layer, and with the thin layer waterproof function that realizes the tencel fibre at the opposite side with the help of the bond line subsides, consequently avoided among the prior art because add the relatively poor problem of water-proof effects that less waterproof material leads to in the special type and the tencel fibre that is thinner for adaptation tencel fibre thickness, still avoided among the prior art to add too much waterproof material in the tencel fibre for reinforcing water-proof effects and lead to the fibre surface fabric to feel hard and make the relatively poor problem of user experience.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
