Problems solved by technology

Wool heating pearl balls are enclosed between the first interlayer and the second interlayer of the cotton clothing. The wool heating pearl balls are made of 3-6D heat-generating fibers with a length of 5-6 cm and 6-8D sheep wool with a length of 5-7 cm. Processed into curved or spherical fibers, using special wool heating pearl balls as thermal fillers, not only increases the elasticity of clothing, improves frictional heat production, but also is smaller in size and lighter to wear, but also because of the heating fiber and sheep The wool is evenly distributed in the sphere, and the friction and entanglement between the fibers is more serious during washing.

Embodiment 1

[0049] Select viscose staple fiber with a single fiber fineness of 7.8dtex and a single fiber length of 25mm as fiber A, a three-dimensional crimped hollow fiber with a single fiber fineness of 3.3dtex, a single fiber length of 51mm, a crimp number of 8 / 25mm, and a hollow rate of 30%. PET staple fiber was used as fiber B, and ordinary PET staple fiber with a single fiber fineness of 0.6 dtex and a single fiber length of 22 mm was used as other fibers. Firstly, the viscose staple fiber and 50% three-dimensional crimped PET staple fiber are mixed in the ratio of 20:80 and opened, and then the prefabricated fiber ball with a diameter of 15mm is obtained through a ball forming machine. Then the remaining 50% of the three-dimensional crimped PET staple fiber and the ordinary PET staple fiber opened cotton are uniformly mixed in the ratio of 40:60 through the cotton blender, and the opened cotton is wrapped on the surface of the prefabricated fiber ball, and finally obtained by the b...

Embodiment 2

[0051] Select viscose staple fibers with a single fiber fineness of 1.2dtex and a single fiber length of 15mm as fiber A, the mixing ratio of fiber A is 5%, and the rest are the same as in Example 1 to obtain the fiber ball of the present invention. The parameters are shown in Table 1.

Embodiment 3

[0053] Only viscose staple fibers with a single fiber fineness of 9.8dtex and a single fiber length of 40mm are selected as fiber A, and a three-dimensional crimp with a single fiber fineness of 3.3dtex, a single fiber length of 51mm, a crimp number of 8 / 25mm, and a hollow rate of 30% Hollow PET short fiber is used as fiber B, without other fibers, and the rest is the same as in Example 1 to obtain the fiber ball of the present invention, and the parameters are shown in Table 1.

Abstract

The invention discloses a fiber ball. The fiber ball comprises a fiber A and a fiber B, the diameter of the fiber ball is 5-30 mm, an inner layer and an outer layer are sequentially arranged on the cross section from inside to outside, and less than 45% of the fiber A is distributed on the outer layer; and the fiber B has a three-dimensional crimp form, and the crimp number is 2-8 / 25mm. The fiber ball is high in fluffiness, soft in hand feeling and washable.

Description

technical field [0001] The invention relates to a fiber ball, in particular to a fiber ball that can be used for filling thermal insulation cotton clothes, sleeping bags or quilts. Background technique [0002] Down is widely used as a filling material for cold-proof clothing such as down jackets and down jackets and cold-proof bedding such as down quilts due to its soft feel, bulkiness and good thermal insulation. However, since down is a natural material obtained from duck or goose, it is difficult to mass-produce it. But also easy to breed insects, causing skin allergies. [0003] As a substitute for down, a fiber ball (also known as granular cotton, pearl ball) has been developed. The fiber ball uses chemical fiber as the main raw material. Various functions such as antistatic. [0004] For example, patent document CN107208321A discloses a polyester hollow fiber spherical body. The spherical body uses a hollow polyester fiber with a single fiber fineness of 2.0-6.6dt...
