It's Polyester, Why To Say Cotton?! (II)



In the last article, we introduced the classification of polyester fillers. In this issue, we will continue to introduce the classification and application of polyester fillers.


05 Dimension

It can be divided into two-dimensional fibers and three-dimensional fibers. Two dimensional cotton, that is, the crimp of fiber is formed in a two-dimensional plane, and a single fiber is wavy. Ultrafine or fine fibers are generally two-dimensional fibers. Three dimensional cotton, that is, the crimp of fiber is formed in three dimensional space, and a single fiber is helical. The latter is curly and compact, not easy to deform, and has better elasticity, feel and comfort. In addition to superfine or fine fibers, medium and coarse fibers can be made into three-dimensional fibers.


06 Length

It can be divided into short, medium and long fibers. The length of short fiber is 2.5-3.4cm; The length of medium fiber is 3.4-6.4cm; The length of long fiber is more than 6.4cm. The length of products used for silk like fillers can reach several meters.


07 Finishing

It can be divided into silicon and non silicon finishing. There are fibers finished with silicon, which feel soft and smooth; And vice versa. Generally, silicon and silicon free products are mixed and used, which can better combine the softness and fluffy of the product, and improve the use value of the final product.


08 Function

It can be divided into antibacterial and flame retardant fibers. First, all kinds of antibacterial and flame retardants are uniformly dispersed in the matrix resin to form a concentrate, namely master batch. After a certain amount of master batch and corresponding resin particles are mixed, the fiber with flame retardant and antibacterial effects on the surface can be prepared according to the fiber processing and molding method.


09 Brand

An enterprise has a high reputation for focusing on the production of polyester fiber, and the common name of its fiber is consistent with its brand. For example, DuPont cotton is the brand name of DuPont. DuPont cotton is a generic term for the polyester fiber produced by DuPont, which usually refers to three-dimensional four hole cotton and three-dimensional seven hole cotton.


3、 Application of Polyester Filler

All the above fibers have their own advantages in terms of performance, price, production and maintenance. Through the above simple classification, the basic characteristics and principles of various single fibers are preliminarily clarified. So, which products do many gorgeous "cotton" usually correspond to?

No. Name Product
1 Cloud silk cotton, imitation silk cotton, high elastic cotton 3D one hole, four hole, seven hole quilt core and pillow core
2 feather silk cotton, goose down like superfine or fine fiber pillow core and quilt core
3 Carding cotton, sheet cotton, non collodion cotton, shaped cotton Serial number 1-2 All products
4 Antibacterial cotton, flame retardant cotton Serial number 1-2 All products
5 DuPont cotton Serial number 1-2 All products


In fact, each gorgeous "cotton" contains a lot of positive and negative information, which is the embodiment of the comprehensive characteristics of the product. It can only be achieved through the mixing and optimization of various fibers. The positive purpose is to better combine the softness, bulkiness and durability of core products. Improve the added value and degree of differentiation of products to meet the requirements of customers to continuously improve their sense of experience. However, the process of mixing and optimization is relatively complex and cannot be standardized at present. Which materials are more suitable for pillow core and quilt core? In many cases, there is no obvious boundary.


Here comes the key point. How can we make it happen after so much talk? When the hotel purchases core products, specific requirements can be indicated in the column of product description according to the above product classification. For example: feather silk pillow core (original polyester 1.33D fiber 300g+3D fiber 800g...). It is not important to choose a name, but the quality description is important!


It's polyester, but it's cotton?! According to SIDEFU, first of all, consumers' preference for natural cotton has been deeply rooted for a long time; Secondly, after the polyester staple cotton is loosened, its appearance and thermal insulation performance are similar to cotton, even better than cotton! Thirdly, the producers expect to integrate the advantages of the two fibers to enhance the consumer experience. Although there is no way to verify the answer, we have a preliminary understanding of the relationship between polyester and gorgeous "cotton" through our understanding of polyester fiber, with the purpose of making the product full of more positive energy!
