[0021] The drawings are only used for illustrative purposes and cannot be understood as limiting the patent; in order to better illustrate the embodiments, some components of the drawings may be omitted, enlarged or reduced, and do not represent the actual product size.
[0022] For those skilled in the art, it is understandable that some known structures in the drawings and their descriptions may be omitted. The technical solutions of the utility model will be further described below in combination with the drawings and embodiments.
[0023] An anti-mildew fabric includes a pile layer 1, a base cloth layer 2 and an antibacterial layer 3 arranged in sequence, the pile layer 1 and the antibacterial layer 3 are both embedded with anti-mite microcapsules 4 on the pile, the particle size of the anti-mite microcapsules 4 is 2-4 μm, the anti-mite microcapsules 4 include a chitosan shell 41 and a mite repellent agent 42 filled in the chitosan shell 41;
[0024] The preparation method of the anti-mite microcapsule 4 is as follows: a certain amount of mite repellent agent 42 (natural plant essential oil, such as clove essential oil, lavender essential oil, eucalyptus oil, cypress oil, citrus essential oil, wormwood oil, etc.) and sorbitan oleate are weighed and stirred and mixed uniformly; a certain amount of degraded chitosan and sorbitan monooleate polyoxyethylene ether are weighed and added into distilled water and stirred and mixed uniformly; the above two mixtures are poured into a three-necked flask and stirred at 50℃ and 200r / min for 30min. Under the conditions of temperature control and low-speed stirring, 2% NaOH solution is added dropwise into the mixture to adjust the pH value to make the chitosan undergo single condensation reaction for 10-15min, so as to form the chitosan shell 41, and the chitosan shell 41 embeds the mite repellent agent 42 into its interior. Distilled water is added to dilute the mixture and rapidly cooled with an ice water bath, and an appropriate amount of glutaraldehyde is added, and cross-linking and solidification are carried out at 200-300r / min under low temperature (0-5℃) for about 1h. After the reaction is completed, the anti-mite microcapsule 4 is obtained by filtration, washing and drying at room temperature. The above preparation method is an interfacial polymerization method commonly used for preparing microcapsules.
[0025] The antibacterial layer 3 is woven by antibacterial yarn 31, the linear density of the antibacterial yarn 31 is 7.3tex, the pile layer 1 is prepared by using sanding process on one side of the base cloth layer 2, and the thickness of the pile layer 1 is 2mm.
[0026] In some embodiments, the antibacterial yarn 31 is twisted from cotton fibers 311 and hemp fibers 312, the mass fraction of the hemp fibers 312 is 70%, and the average length of the hemp fibers 312 is 23.5 mm. Hemp products not only have unique antibacterial and health care functions, but also are high-value biomass resources with low carbon quality. Hemp fabrics have been widely used in clothing, home textiles, shoemaking and other fields.
[0027] In some embodiments, the base fabric layer 2 is knitted, the stitch structure of the base fabric layer 2 is double rib stitch, and the base fabric layer 2 is knitted from pure cotton yarns with a fineness of 14.5 tex. The fabric structure of the antibacterial layer 3 is plain weave.
[0028] In some embodiments, the thickness of the base fabric layer 2 is 4 mm, the thickness of the antibacterial layer 3 is 3 mm, and the base fabric layer 2 and the antibacterial layer 3 are connected by sewing threads.
[0029] In some embodiments, the base fabric layer 2 is knitted in six rows per cycle. In the arrangement order from the top needle disc to the bottom needle cylinder, the first row is in turn: tuck stitch, floating thread stitch, floating thread stitch, tuck stitch; the second row is in turn: floating thread stitch, floating thread stitch, loop stitch, loop stitch; the third row is in turn: loop stitch, loop stitch, floating thread stitch, floating thread stitch; the fourth row is in turn: floating thread stitch, tuck stitch, tuck stitch, floating thread stitch; the fifth row is in turn: floating thread stitch, floating thread stitch, loop stitch, loop stitch; and the sixth row is in turn: loop stitch, loop stitch, floating thread stitch, floating thread stitch.
[0030] The above-mentioned mildew-proof fabric can be prepared by the following method:
[0031] (1) Preparing the antibacterial yarn 31. The spinning process of the antibacterial yarn 31 includes: scutching, hemp pretreatment, carding, drawing, combing, roving, and spinning. The pretreatment of hemp improves the rigidity of the fibers and improves the spinnability. Spinning hemp fibers 312 alone will cause unstable quality indicators such as unevenness of cotton lap. Spinning hemp fibers 312 and long-staple cotton together can solve the problem of poor spinnability of hemp fibers 312 and difficulty in spinning high-count yarns. The hemp fibers 312 and long-staple cotton are first mixed into slivers according to a certain dry weight ratio, then the long-staple cotton slivers are mixed with the cotton / hemp slivers to ensure the content of the hemp fibers 312 in the yarn.
[0032] (2) Knitting the base fabric layer 2 and the antibacterial layer 3. The base fabric layer 2 is knitted on a 4-needle double-jersey machine with a gauge of 38 needles / 25.4 mm and a cylinder diameter of 36 inches. The triangular arrangement is as shown in Figure 5 , and the mass of the finished fabric is 230 g / m 2 . The antibacterial layer 3 is knitted on a single-jersey circular knitting machine.
[0033] (3) sanding treatment. The base fabric layer 2 is sanded to obtain the pile layer 1. An SMW-4C combined carbon fiber sander is used, and the process parameters are as follows: speed 25 m / min, sanding roller speed 1200 r / min, carbon fiber roller speed 950 r / min, and covering depth 15 mm. The process flow is six-roller sanding→ four-roller carbon sanding→ sanded fabric→ brushing dust removal→ fabric falling.
[0034] (4) sewing. The base fabric layer 2 and the antibacterial layer 3 are sewn together by a sewing machine.
[0035] (5) anti-mite finishing. The finishing process is: liquid containing anti-mite microcapsule 4→ dipping (30 min)→ rolling (70% rolling rate)→ pre-drying (80℃, 5 min)→ baking (100℃, 3 min)→ washing with clean water→ white drying. Since the cell wall surface of the cotton fiber 311 and the hemp fiber 312 has a large number of cracks and gullies, the small-scale anti-mite microcapsule 4 will be embedded in the cracks and gullies during rolling, thereby being fixed on the pile layer 1 and the antibacterial layer 3. The anti-mite agent 42 in the chitosan shell 41 can slowly volatilize to achieve the anti-mite effect.
[0036] Obviously, the above embodiments of the present application are merely examples for clearly illustrating the present application, and are not intended to limit the embodiments of the present application. For those skilled in the art, other different forms of changes or modifications can be made on the basis of the above description. Here, it is not necessary and impossible to enumerate all the embodiments. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
