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 wind-feeding and filling 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. .

[0032] The percentage by weight of table 2 hollow polyester staple fiber and superfine denier high hollow polyester staple fiber

Abstract

The polyester fiber filler is the combination of the regular hollow cut staple polyester fiber and a superfine super high hollow cut staple polyester fiber. Their weight ratings are hollow cut staple polyester fiber 25%-75%, superfine super high hollow cut staple polyester fiber, with their optimum weight rating of 50%: 50%. It also provides a production process for filling the above said materials through the process of opening picking, mixing, and carding and final air blowing suede. The filled product with this process looks even and trim, it is light, fluffy, sustainable elastic ability, fine heat protection, soft in touching, and provides people with refined living quality.

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...
