1. Fabric: high-density fabrics are generally used for high-grade bedding, and medium-density or low-density fabrics are generally used for middle and low-grade bedding. It can be distinguished by the naked eye and touch. High-grade bedding fabrics generally use high-density cotton cloth. Blended or chemical fiber fabrics are generally selected for middle and low-grade products. Poplin, twill and satin fabrics are better than plain fabrics. 2. Fillers: soft cotton, loose cotton, three-dimensional curled single-hole cotton, four-hole cotton, seven-hole cotton, slip cotton, sun velvet cotton, etc. It is the choice of middle and high-grade bedding. Low-grade bedding is glue-sprayed cotton and ordinary polyester cotton. Generally, it has not been sorted, and the quality is poor. If you don't distinguish carefully, it's difficult to distinguish. Usually wedding bedding and children's bedding are basically the above ingredients. 3. Quality: The sewing quality can be seen from whether the sewing stitches are uniform, fine and straight, whether there are jumpers or too many threads. High-grade bedding has good sewing quality, while middle and low-grade bedding is not suitable for sewing quality. 4. Packaging choice: high-grade and mid-grade bedding should be embossed, transparent, moisture-proof, thirst-proof and gift-packed. The package contains text or picture signs, fabric components, fillers, product numbers and qualified seals. 5. Brand: A good brand manufacturer will try to promote it in order to expand the market and guide consumers through advertisements. And in order to maintain our brand form, we will do better in quality, style, color and after-sales service. 6. Color: First of all, it depends on the color and style you appreciate. Good colors are generally more durable, that is, the more you look, the better you look, and the taste of colors is artistic. Some colors look good at first sight, but after a long time they feel ugly and the colors don't last. 7. Style: Bedding styles mainly include patterns and cuffs. Generally, sail fabrics and fillers are stitched together through patterns, which has a strong three-dimensional effect and a flat appearance, but it is not easy to wash. Dry cleaning is recommended, because thirsty washing will affect the original effect of cotton. Generally, the looping method is to put the quilt core through the veil, then attach the quilt cover, and only wash the quilt cover when cleaning, which is convenient and practical. 8. Service: Look at the service attitude of shopping malls and manufacturers. Good shopping malls and manufacturers generally have better after-sales service. Such as warranty cards, customer clubs, etc. Products with quality problems can be returned, and pay attention to customer information feedback.
