Abstract
Description
Technical Field
[0001] The invention belongs to silk modification technology, and specifically relates to a washable silk quilt and a preparation method thereof. Background Art
[0002] As a common household product, the washability of silk quilt has always been the key to restricting its performance. CN110973931A discloses a method for making a washable silk quilt, which includes selecting cocoons, boiling cocoons, peeling silkworms, and drawing silk: the drawing silk should be carried out on a special operating platform, each person holds a corner of a cotton sheet, pulls the cotton sheet evenly in four directions, pulls the silk in parallel directions, and makes a quilt cover of the silk quilt, sews the side of the silk quilt cover with needle and thread, evenly finds 10 points on the quilt, and sews and fixes them at each point with needle and thread, and sews the extension line on the basis of the 10 points, so that the quilt cover and the quilt cover form a rectangular block sewing shape, and then the corner connection between each rectangular block is sewn into a circular structure shape as the center of the circle, and the silk quilt is formed after completion, and the silk quilt is separated and fixed as a whole, so that the silk inside the silk quilt will not be regionally displaced when the silk quilt is washed, effectively avoiding the shrinkage and deformation of the silk quilt, and improving the service life of the silk quilt after washing. CN112826286A adopts appropriate auxiliary agents and degumming methods according to the properties of sericin, completely removes the sericin of the outermost layer, partially removes the sericin of the middle layer, and retains all the sericin of the innermost layer, and uses a mixture of glutaraldehyde and polyamide formaldehyde as a solidifying agent to improve the fluffiness of silk and acid and alkali resistance. The silk quilt obtained after the sericin fixation treatment has sericin firmly coated on the outer layer of silk fibroin. The sericin is insoluble in water, thereby achieving the washability of the silk quilt. After multiple washings, the quilt still has the characteristics of lightness, fluffiness, and good warmth retention. CN114287784A discloses a washable and sun-exposure silk quilt and a preparation method thereof, wherein the washable process specifically adopts: amount of clean water: inject clean water according to 70-80% of the capacity of the rear material tank equipment; use of auxiliary agents and dosage: 0.6-0.7% wof glacial acetic acid, 6-7% wof hydrophilic silicone oil softener, 30g / L fluorine-free waterproof, 5g / L cross-linking agent; treatment liquid temperature control: about 40°C; amount of silk floss added: 50-80kg / time (calculated by dry floss weight); soaking treatment time: 20-30min, optimization and innovation are carried out on the original production basis, the softener is changed from the original general specification to hydrophilic silicone oil softener, and fluorine-free waterproof agent, cross-linking agent and related auxiliary agents of the sun-exposure process are added to make the washable and sun-exposure silk floss.
[0003] It can be seen that the existing preparation process for washable silk quilts is too complicated and cannot be industrially produced, and the prepared products cannot be eaten. The inventor previously disclosed a method for waterproof finishing of a washable silk quilt, comprising the following steps: (1) preparing a waterproof finishing agent: the waterproof finishing agent comprises 2-6% by weight of waterproof agent A, 0.6-3.6% by weight of waterproof agent B, 0.5-5% by weight of silk quilt softener, 0.2-0.8% by weight of silk quilt bulking agent, and water; the waterproof agent A is polymethyl hydrogen siloxane, and the waterproof agent B is polydimethyl siloxane; (2) heating the waterproof finishing agent to 35-45°C, and immersing the dry silk quilt in it for 20-30 minutes, then dehydrating, pre-baking, and baking the impregnated silk quilt; and making a silk quilt using conventional methods, which can still maintain the original resilience, bulkiness, and softness after 5 washes. Adhering to the needs at the time, the main consideration was the resilience of the silk quilt after washing, and the impact of washing on functionality was not studied. Summary of the invention
[0004] The invention discloses a washable silk quilt and a preparation method thereof. The immersion water bath method is adopted to maintain the advantage of industrial production. Meanwhile, by changing the formula of the finishing liquid, the physical properties of the silk quilt are maintained while the functional properties such as antibacterial and negative ion are still maintained.
[0005] The present invention adopts the following technical solution:
[0006] A washable silk quilt and a preparation method thereof. Nano-active polysiloxane and a catalytic cross-linking agent are added into water, and then a surface-treated functional material is added to obtain a finishing liquid; a silk floss sheet is immersed in the finishing liquid, and then taken out, washed, dried, and baked to obtain a washable silk floss sheet; finally, the washable silk floss sheet is prepared into a washable silk quilt.
[0007] A washable silk floss sheet for a washable silk quilt and a preparation method thereof. Nano-active polysiloxane and a catalytic cross-linking agent are added into water, and then a surface-treated functional material is added to obtain a finishing liquid; the silk floss sheet is immersed in the finishing liquid, and then taken out, washed, dried, and baked to obtain the washable silk floss sheet.
[0008] In the present invention, the method of preparing the washable silk cotton sheet into the washable silk quilt is a conventional technology in the art and does not affect the realization of the technical effect of the present invention. The present invention uses nano-active polysiloxane and catalytic cross-linking agent as washable finishing, maintains the advantages of the existing washable silk quilt being fluffy and resilient, and uses functional materials treated with coupling agents to modify the function of the silk quilt, and performs functional finishing while washing the washable finishing. It is unexpectedly found that after washing, the function of the functional material is still maintained.
[0009] In the present invention, the immersion is carried out under shaking. Preferably, during the immersion, the temperature is 30-50° C., the time is 1-3 hours, and the bath ratio is 1:(10-20), preferably 1:(10-15).
[0010] In the present invention, in the finishing liquid, the concentration of nano-active polysiloxane is 10-20 g / L, the concentration of the catalytic cross-linking agent is 10-20 g / L, and the concentration of the surface-treated functional material is 20-50 g / L. Preferably, in the finishing liquid, the concentration of nano-active polysiloxane is 15-20 g / L, the concentration of the catalytic cross-linking agent is 10-15 g / L, and the concentration of the surface-treated functional material is 20-45 g / L.
[0011] In the present invention, the surface treatment is coupling agent treatment, the coupling agent is a silane coupling agent, the surface of the functional material is modified, the dispersibility is improved, the agglomeration is reduced, the non-polar functional groups are increased, and the bonding force between the silk floss sheet and the modified material is effectively improved.
[0012] In the present invention, the drying temperature is 100-105° C., and the time is 1-2 minutes; the baking temperature is 150-160° C., and the time is 50-70 seconds.
[0013] Although washable silk quilts are available on the market, most silk quilts are often made into thin seam quilts and are not truly washable. According to existing information, the waterproof finishing method used in the prior art for textile fabrics cannot be used to treat silk quilts. The reason is that the fluffiness, resilience, softness, etc. of the silk quilt obtained by the finishing method will be reduced, and the original excellent wearability of the silk quilt cannot be achieved. The inventor previously disclosed a waterproof finishing method for a washable silk quilt, which can still maintain the original resilience, fluffiness and softness after 5 washings. Sticking to the needs at the time, the main consideration was the resilience of the silk quilt after washing, and the effect of washing on functionality was not studied. The present invention adopts a new waterproof finishing system to achieve a washable finishing that integrates waterproofing, softness, and fluffiness. In particular, in combination with functional materials, it is unexpectedly found that the function of the functional material is still maintained after washing. DETAILED DESCRIPTION
