Name: Silk Fibroin Methacryloyl

Product Overview

Silk Fibroin (SF) is a polymer polypeptide consisting of multiple amino acids derived from the degumming process of silkworm silk.SF molecule consists of a hydrophobic peptide chain (H chain) and a hydrophilic peptide chain (L chain).The special amino acid sequence of the H chain and the L chain enables it to form a variety of protein secondary conformations. It is possible to control the secondary structure of filipin proteins to effectively control various properties of filipin materials, including the preparation of high-strength and high-orientation materials. Because of its biocompatibility, biodegradability, high tensile strength, etc., it has been used in various biomedical fields, including wound dressings, artificial blood vessels, cell culture, etc., and it has been certified by the U.S. Food and Drug Administration (FDA), which makes it a very promising biomaterial.

Silk proteins cannot be dissolved in water due to their own high degree of crystallinity, and this hydrophobic property makes it difficult to obtain a homogeneous structure when compounded with hydrophilic systems such as hydrogels. In order to improve the dispersibility of filipin, filipin solutions are often obtained by salt dissolution and dialysis, followed by the preparation of the corresponding composite materials. The preparation process of silk protein solution is cumbersome, with poor stability and easy spontaneous gelation, which limits its biological applications.

In order to meet different application requirements, XFNANO team selects high-quality mulberry cocoons, and through a series of processes, we have obtained the silk protein products with good water solubility, stability, and material extensibility, which can be quickly dissolved in water, and can be used in conjunction with a variety of types of hydrogels, such as GelMA, HAMA and so on, in order to adapt to the needs of different application fields.

Oversized
Size: Queen (Pack of 2), Color: White
I have chronic neck pain. I am forever buying new pillows. Sometimes I think I found the perfect pillow but then three months later they’re losing their loft. I thought I would give these pillows to try since the stuffing is removable. Now these pillows are really oversized. To the point where I thought that they had sent me king-size pillows but I double checked the packaging and they were Queen. I ended up having to buy king-size pillowcases for them because they just barely fit in the queen size and the pillowcases would always end up pulling back from the edge. So that’s a negative one star there. Now I’ve been sleeping on these pillows for a while and they have held up well. I did end up removing some of the stuffing because it was just too much. I’m a side sleeper and when I use this pillow, it does a good job of keeping my neck in alignment. However, the pillow tends to migrate up as I sleep. Or I tend to slip down off the pillow, either or. So that’s why I’ve removed a second star. Maybe if I removed more stuffing that wouldn’t happen, but then I feel like the loft would be too little. I will say that these provide great support when sitting up in bed reading or watching TV. So would I buy them again? Probably not. Am I going to keep using them? Yes

Amazing - Stop Scrolling and Buy This Pillow
Size: Queen (Pack of 1), Color: White
I have been an Amazon customer ever since the very beginning, and this is my first review. Not because I haven’t purchased tons of amazing things (and a few bad ones), just never felt the need. However, I researched pillows for longer than I care to admit, and decided on this one. I’ve had it for about six months and absolutely love it. No lie, I genuinely look forward lying my big head on it after a long day. I am a side sleeper, but flip flop all around through the night and it’s great in every position. Pros: Stays nice and cool, which is soothing regardless of the time of year. Has a sort of quilted textured pattern on the zip up cover, gives it a luxury feel, that breaths nicely even when a pillow case is added. The fill is fully adjustable to your preference. I knew it came with extra filling but was worried it would not be enough. Wrong. It was very full and I ended up taking some out until it was perfect. It comes vacuum sealed and suggests it may take some time to fully take shape. However, I found it to be about 90% almost instantly and was sleeping on it a couple hours later. There was no unpleasant scent sometimes associated with memory foam items. The foam itself is very nice, a mix of what appears to be shredded and cotton candy cloud like. Very brilliant idea, as it is somehow supportive, soft and firm all at once. The affordability of this pillow compared to some of the others in this category can’t be overstated. Oh, and the packaging was very thoughtfully and securely done. If you are like me, an over thinker, I would suggest just taking this for a spin. It’s amazing. I’m not a bot, or working for the company. I’m just truly satisfied, love this pillow, and have been sleeping great.

It's the perfect pillow!
Size: Queen (Pack of 1), Color: White
I purchased this pillow specifically for its customizable fill feature, which allows you to add or remove stuffing to suit your personal comfort needs. Due to the unique curvature of my cervical spine—forward at the neck rather than backward—I require a soft, semi-flat pillow rather than one that is thick or firm. Additionally, I often experience ear discomfort by morning, so a gentler surface is essential. Upon adjusting the fill, I was pleasantly surprised by the generous amount of stuffing included. There was enough to fill an additional pillowcase, and I estimate it could easily create four to five more pillows. The ability to modify the pillow’s firmness at any time is an outstanding feature that makes it adaptable for a wide range of preferences and sleep styles. This pillow has exceeded my expectations in both comfort and versatility. I highly recommend it to anyone seeking a personalized sleep experience.

Good quality pillows overall
Size: King (Pack of 2), Color: White
Got a set of these for my wife and myself as we were struggling with our old pillows. These have some really good qualities and some things we'd like to see changed. First, the good: These are look and feel like they are high quality and made with good materials. The foam itself has a very nice feel to it. We love the fact they are adjustable to add or remove foam. They come with a pretty substantial amount already in the pillow. We appreciate the CertiPur certification. Now the improvements or changes we'd like to see: The foam, while feeling great, doesn't bounce back well if you scrunch your pillows, and so every day you have to fluff and reshape the pillow, moreso than some other memory foam pillows we've owned. One side of the pillow is cooled and you can feel that even through the pillow case, and that's a great thing. However, one side is not cooled and we'd have preferred if both sides were made of the cooling material. Overall, these are good pillows and we are not disappointed with the purchase. They are not, however, our perfect pillows (which do seem hard to find), and at some point in the future will probably make their way to the guest bedroom. We would rate them as some of the better pillows we've tried and feel most people would probably like them.

Perfect Pillow
Size: Queen (Pack of 1), Color: White
These are the best pillows ever. You can adjust the firmness or softness to whatever you want. For years i used a soft latex pillow , which you cant get anymore. I will never use another pillow. I have purchased 6 of these after the first one. You pick your own comfort level. Best ever. No more neck aches.
