Definitions
- a composite nonwoven fabric having absorbent quick-drying properties and an article containing the same are disclosed. More specifically, a composite nonwoven fabric having absorbent quick-drying properties, which facilitates sweat discharge and has excellent drying properties compared to existing spunbond nonwoven fabrics, and an article containing the same are disclosed.
- Spunbond nonwoven fabric for sanitary materials used in diapers or sanitary napkins is mainly applied to back sheets or waist bands.
- the parts of the human body that come into contact with the backsheet or waistband must be non-toxic because they are the areas where the skin touches these backsheets or waistbands directly or the backsheets or waistbands are touched by hands.
- sweat can easily occur on the skin, so breathable products are preferred to speed up the evaporation of sweat.
- Polyolefin-based nonwoven fabrics are widely used for sanitary materials because they are non-toxic, and because they ensure breathability, they are even more widely used for sanitary materials.
- most conventional polyolefin-based nonwoven fabrics are hydrophobic and breathable, but do not have the ability to easily discharge sweat to the outside of the nonwoven fabric. Therefore, when used in the summer or for long periods of time, sweat easily accumulates in the nonwoven fabric, causing rashes or sores on the skin. .
- One embodiment of the present invention provides a composite nonwoven fabric with absorbent quick-drying properties, which facilitates sweat discharge and has excellent drying properties compared to existing spunbond nonwoven fabrics.
- Another embodiment of the present invention provides an article comprising a composite nonwoven fabric having absorbent and quick-drying properties.
- One aspect of the present invention is,
- a nonwoven fabric layer (A) composed of first thermoplastic resin fibers
- It includes a nonwoven fabric layer (B) composed of second thermoplastic resin fibers,
- the ratio (Pb/Pa) of the pore size (Pb) of the non-woven fabric layer (B) to the pore size (Pa) of the non-woven fabric layer (A) is 1.5 to 3.0,
- a composite nonwoven fabric is provided wherein the ratio (Tb/Ta) of the thickness (Tb) of the nonwoven fabric layer (B) to the thickness (Ta) of the nonwoven fabric layer (A) is 1.0 to 3.0.
- the composite nonwoven fabric may have an absorption rate of 20 seconds or less.
- the composite nonwoven fabric may be a spunbond nonwoven fabric with an embossed pattern.
- the composite nonwoven fabric has an embossing ratio of 11% to 18% and may include a plurality of embossed patterns arranged continuously and spaced apart from each other.
- the composite nonwoven fabric may have a unit weight of 10 to 60 gsm.
- Another aspect of the present invention is,
- An article comprising the composite nonwoven fabric is provided.
- the article may include sanitary materials.
- the sanitary materials may include diapers, sanitary products, or masks.
- the article may be configured such that the non-woven fabric layer (B) is disposed on the side that touches the skin of the human body.
- the composite nonwoven fabric with absorbent and quick-drying properties facilitates sweat discharge and has excellent drying properties compared to existing spunbond nonwoven fabrics. Therefore, the composite nonwoven fabric can have a sufficient absorption rate and quick-drying properties to be used as a nonwoven fabric for sanitary materials.
- the composite nonwoven fabric can be used in the backsheet of sanitary materials, the waist band of sanitary materials, or the top sheet of sanitary materials, thereby providing sanitary materials with excellent absorbency and excellent quick-drying properties.

Description
흡수속건성을 갖는 복합 부직포 및 이를 포함하는 물품이 개시된다. 보다 상세하게는, 기존 스펀본드 부직포에 비해 땀 배출이 용이하고 건조성이 뛰어난, 흡수속건성을 갖는 복합 부직포 및 이를 포함하는 물품이 개시된다.A composite nonwoven fabric having absorbent quick-drying properties and an article containing the same are disclosed. More specifically, a composite nonwoven fabric having absorbent quick-drying properties, which facilitates sweat discharge and has excellent drying properties compared to existing spunbond nonwoven fabrics, and an article containing the same are disclosed.
기저귀 또는 생리대에 사용되는 위생재용 스펀본드 부직포는 주로 백시트나 허리밴드에 적용된다. Spunbond nonwoven fabric for sanitary materials used in diapers or sanitary napkins is mainly applied to back sheets or waist bands.
백시트나 허리밴드와 접촉하는 인체 부위는 피부가 이들 백시트나 허리밴드에 직접 닿거나 손으로 이들 백시트나 허리밴드가 만져지는 부위이기 때문에 독성이 없어야 한다. 특히, 백시트나 허리밴드가 피부와 접촉하게 되면 피부에서 쉽게 땀이 발생할 수 있기 때문에 땀의 증발을 빠르게 하기 위해 통기성이 있는 제품이 선호된다. The parts of the human body that come into contact with the backsheet or waistband must be non-toxic because they are the areas where the skin touches these backsheets or waistbands directly or the backsheets or waistbands are touched by hands. In particular, when the backsheet or waistband comes in contact with the skin, sweat can easily occur on the skin, so breathable products are preferred to speed up the evaporation of sweat.
폴리올레핀계 부직포는 독성이 없기 때문에 위생재용으로 널리 사용되고 있으며, 통기성도 확보되기 때문에 위생재용으로 더 더욱 널리 사용되고 있다. 하지만, 종래의 폴리올레핀계 부직포는 대부분 소수성이고, 통기성은 있지만 땀을 쉽게 부직포의 외부로 배출하는 기능이 없어 여름이나 장시간 사용시 부직포내에 쉽게 땀이 차게 되어 피부에 발진이나 짓무름 등이 발생하는 문제점이 있다. Polyolefin-based nonwoven fabrics are widely used for sanitary materials because they are non-toxic, and because they ensure breathability, they are even more widely used for sanitary materials. However, most conventional polyolefin-based nonwoven fabrics are hydrophobic and breathable, but do not have the ability to easily discharge sweat to the outside of the nonwoven fabric. Therefore, when used in the summer or for long periods of time, sweat easily accumulates in the nonwoven fabric, causing rashes or sores on the skin. .
