Problems solved by technology

[0002] The existing fluffy non-woven fabrics are produced in many ways, but most of them are made of polyester plus a small amount of low-melting point thermally bonded fibers, or are made by spraying glue after drying, and the product has better bulkiness , but feel harder
In order to improve the hand feeling, it is also made of 100% low-melting point composite fiber. The product made of 100% low-melting point composite fiber feels very weak, but the bulkiness is not good and the pores are not enough, which affects the performance of non-woven fabrics.
Moreover, the above-mentioned processing technology is relatively complicated, and the cost is relatively high, which has a great impact on the environment.

Embodiment 1

[0017] The manufacturing process of fluffy non-woven fabric comprises the following steps:

[0018] a. Open and mix the crimped hollow fiber and low-melting composite fiber, put the agglomerated crimped hollow fiber and low-melting composite fiber into the three-roller opener, and the three-roller opener adopts Taiwan Riwei non-woven equipment Three-roller opener: through the three-roller opener, the agglomerated fibers can be dispersed into loose fiber filaments, and the dispersed fibers are mixed and dispersed in the three-roller opener disorderly.

[0019] b. Combing the above-mentioned opened and mixed fibers into a fiber web; the mixed fibers are carded on a non-woven carding machine, and the non-woven carding machine combs the fibers to form upper and lower layers of fiber webs, and transports them to the next process.

[0020] c. The fibers are bonded through hot air; this step is carried out in an oven, and the non-woven fabric carding machine transports the carded upp...

Embodiment 2

[0025] The manufacturing process of the fluffy non-woven fabric in this example is basically the same as that of Example 1, the difference is that in step a, the crimped hollow fiber accounts for 25% by weight, and the low-melting point composite fiber accounts for 75% by weight ; The working temperature of the oven in step c is 125°C, and the hot air penetration speed is 8m / s. The fluffy nonwoven fabric obtained through the manufacturing process of the fluffy nonwoven fabric in this embodiment is basically the same as the fluffy nonwoven fabric obtained in Example 1.

Embodiment 3

[0027] The manufacturing process of the fluffy non-woven fabric in this example is basically the same as that of Example 1, the difference is that in step a, the crimped hollow fibers account for 28% by weight, and the low-melting point composite fibers account for 72% by weight ; The working temperature of the oven in step c is 130° C., and the hot air penetration speed is 11 m / s. The fluffy nonwoven fabric obtained through the manufacturing process of the fluffy nonwoven fabric in this embodiment is basically the same as the fluffy nonwoven fabric obtained in Example 1.

Abstract

The invention discloses a manufacturing process of fluffy non-woven fabrics. The manufacturing process comprises the following steps: a, opening and mixing curly hollow fibers and low-melting-point complex fibers; b, combing the above opened and mixed fibers to form a fiber web; c, performing hot wind penetrating bonding on the fibers; d, and rolling up. The beneficial effects of the manufacturing process of fluffy non-woven fabrics are that through the above steps, the curly hollow fibers and low-melting-point complex fibers can be fully mixed, and the fiber web which is firm in bonding is formed, and the obtained fluffy non-woven fabrics is advantaged by good filling power, high elasticity, and high porosity, and the fluffy non-woven fabrics has good permeable and water absorbing capability to satisfy application requirement, and the process is simple, material integrated cost is low, and production process is very environmentally friendly.

Description

technical field [0001] The invention belongs to a method for manufacturing non-woven fabrics, in particular to a manufacturing process for fluffy non-woven fabrics. Background technique [0002] The existing fluffy non-woven fabrics are produced in many ways, but most of them are made of polyester plus a small amount of low-melting point thermally bonded fibers, or are made by spraying glue after drying, and the product has better bulkiness , but feel relatively hard. In order to improve the hand feeling, it is also made of 100% low-melting point composite fiber. The product made of 100% low-melting point composite fiber feels very weak, but the bulkiness is not good and the pores are not enough, which affects the performance of non-woven fabrics. Moreover, the above-mentioned processing technology is relatively complicated, and the cost is relatively high, which has a great impact on the environment. Contents of the invention [0003] It is an object of the present inve...
