Problems solved by technology

However, because the degree of crimp (wave height, width and frequency) between them does not change, and the difference in fiber length is small, although there is a difference in thickness, but the gradient is small, this type of pillow filler has a large gap between fibers, and the filler The density of the pillow is small. After the pillow core has been used for a period of time, due to the long-term weight from the human head, the filling gap becomes smaller, the density increases, and the height of the pillow core decreases. Fiber winding and agglomeration deform the pillow core. Decreased bulkiness affects the use value of the pillow core

Abstract

A production technology for PET slow recovery filler comprises the following steps: manual fiber blending→first fluffing→second fluffing →filling→sealing. Optimized blending is performed on PET or PET blended three-dimensional crimp fiber being 10-20 mm in length and 3-6 dtex in fineness and known PET or PET-blended three-dimensional crimp fiber. During blending, the PET three-dimensional crimp fiber and the known PET three-dimensional crimp fiber are designed having a gradient relation regarding thickness, length, crimp, and quantity. Accordingly, a third filler can enter the gaps between fibers of the second filler, the second filler can enter the gaps between fibers of the first filler, a three-dimensional structure is formed after the blending of similar fibers, and when the three-dimensional structure receives external pressure, the degree of deformation of the pillow filler is reduced due to the three-dimensional supporting effect; and meanwhile, by optimization of the relation between thickness, length, degree of curvature, and quantity of the three kinds of filler, undue reduction of fill power of the pillow caused by excessive increase in filler density is avoided.

Description

technical field [0001] The invention specifically relates to a production process of polyester slow-rebound filler. Background technique [0002] At present, the ordinary artificial fiber pillows on the market are composed of artificial chemical fibers, and artificial fibers are the most popular, high-quality and cheap materials, so the cost of ordinary artificial fiber pillows is low. In addition, artificial fiber pillows are easy to clean, but due to the lack of chemical fiber materials Elastic and airtight, it will deform and agglomerate after a long time, making the pillow uneven. Nowadays, many people like to use memory pillows. The material of memory pillows is high-density, shock-absorbing, and breathable memory technology cotton. The memory technology cotton is made of pure natural cork through dozens of special processes. The cork particles are soft, elastic, and lightweight. Lightweight, good sweat absorption, and high air permeability, users also [0003] The sh...
