Embodiment

[0043] The manufacture method of described silk soft hot-air nonwoven fabric, comprises the following steps:

[0044] (1) Feeding: put the first component and the second component of the opened cotton bale into No. A fiber is put into the opener according to the ratio stated in the formula;

[0045] (2) Opening and blending: the opening machine loosens the agglomerated above-mentioned fibers, then sends the opened fibers into the cotton mixing box, and fully mixes the fibers;

[0046] (3) Carding: the mixed fiber is sent into a carding machine for sufficient carding, and the fiber is carded into a monofilament and spread into a uniform fiber web;

[0047] (4) Hot air bonding: Send the above-mentioned fiber web into a hot air oven, through the hot air flow inside the hot air oven, the hot air flow penetrates the fiber web to heat the fibers, the cortex material PE absorbs a certain amount of heat and produces melting flow recrystallization, the fiber Self-adhesive reinforceme...

Abstract

The invention provides a silky through-air thermal bonded nonwoven and a manufacturing method thereof. The silky through-air thermal bonded nonwoven is made of a PE / PET sheath-core composite fiber with a concentric structure, and a sheath layer material of the PE / PET sheath-core composite fiber is PE and a core layer material is PET; the PE / PET sheath-core composite fiber comprises a first component and a second component; the first component is a PE / PET composite fiber with a thickness of 1.5D, a length of 38mm, and a sheath-core ratio of 50 / 50, and the second component is a PE / PET compositefiber with a thickness of 1.2D, a length of 38mm, and a sheath-core ratio of 50 / 50, wherein the mass ratio of the first component to the second component is 2:8. According to the silky through-air thermal bonded nonwoven and the manufacturing method thereof provided by the invention, more than 70% of the fiber arrangement of the prepared silk-soft hot-air nonwoven fabric is longitudinal arrangement, thus the silky through-air thermal bonded nonwoven has excellent silky feeling, is extremely skin-friendly, and has an excellent antibacterial effect; and the manufacturing method is simple, the flexibility is high, and has a good development prospect.

Description

technical field [0001] The invention belongs to the technical field of nonwoven fabrics, and in particular relates to a silky soft air-through nonwoven fabric and a manufacturing method thereof. Background technique [0002] Since entering the 21st century, my country's medical and sanitary textile industry has ushered in an unprecedented growth rate due to the huge demand potential and the continuous growth of the industry scale. At the same time, more and more development bottlenecks and restrictive drawbacks are gradually exposed. In order to ensure hygiene, personal hygiene care products are often disposable products, that is, disposable products. The consumption of these products is huge because they are all disposable products, especially at the current stage of population aging in my country, the health care problems of the elderly are gradually becoming prominent, and the two-child policy that has been opened in recent years has increased the number of newborns, The...
