Problems solved by technology

However, the defect of this fiber material is poor bulkiness and low elastic modulus.
[0004] In the prior art, the production process of filling polyester fiber material filling materials generally includes the following steps: opening → mixing → carding → laying → filling. Good, but not soft enough to handle, not fluffier enough

Embodiment 1

[0029] Opening, mixing, and carding the hollow polyester staple fiber with a weight percentage of 25%:75% and the ultra-fine denier high-high hollow polyester staple fiber, and then air-feed and fill it to obtain the filled product, and measure its bulkiness The compression rate is 71%, the compression rate is 72%, the heat retention rate is 88.58%, the elasticity rate is 89%, and the air permeability rate is 37.6%. From the above data, it can be seen that the above products are light, fluffy, good air permeability, high elastic recovery rate, and warm. The characteristics are good, and the feel is soft and is comfortable.

Embodiment 2～5

[0031] The method and process are the same as in Example 1. The weight percentages of hollow polyester staple fibers and ultra-fine denier high-high hollow polyester staple fibers are shown in Table 2, and the technical indicators of the products obtained after filling are shown in Table 3. From the data in Table 3 and the actual test results, it can be seen that each product in Examples 2 to 5 has the advantages of lightness, fluffiness, good air permeability, high elastic recovery rate, good warmth retention, and soft and comfortable hand feeling. .

Abstract

A kind of polyester fiber filling material, which is made by mixing conventional hollow polyester staple fiber and ultrafine denier high and high hollow polyester staple fiber. Its weight percent content is: 25%-75% of hollow polyester staple fiber; 75%-25% of ultra-fine denier high-high hollow polyester staple fiber, and the optimized weight percentage content is 50%:50%. The present invention also provides a production process for product filling with the above-mentioned polyester fiber filling material. After opening, mixing and carding hollow polyester short fibers and ultra-fine denier high-high hollow polyester short fibers, wind filling is carried out. The various filled products obtained by using the above-mentioned polyester fiber filling materials and filling processes have uniform and smooth appearance, light weight, high bulkiness, long-lasting elastic recovery, excellent warmth retention, and soft hand feeling. People feel comfortable, which can improve sleep and quality of life.

Description

technical field [0001] The invention mainly relates to a polyester fiber core filling material used for textiles and a production process for filling products with the filling material, and belongs to the technical field of textile chemical fibers. Background technique [0002] In recent years, thermal fibers and thermal clothing fabrics have developed rapidly, with different varieties and characteristics, but there are not many changes in the performance of the fibers and the attributes of the fibers themselves, and they are similar or similar. Although the market for thermal fibers is large and demand has been strong, there are not many products with technological content. Studies have shown that hollow fibers are isolated and kept warm through the airflow in a single hole. If the hollow rate of the fiber is too small, it does not have the obvious value of keeping warm. If the hollow rate of the fiber is too large, due to the influence of the subsequent process, it will ca...
