Embodiment approach 1

[0101] Embodiment 1 is a fiber comprising: a matrix polymer comprising an aromatic polyester or nylon-6; and an alkylene oxide-containing nonionic surface compounded within the matrix polymer Active agent; wherein the alkylene oxide-containing nonionic surfactant has a melting point greater than 25°C and an HLB greater than 10.

[0102] Embodiment 2 is the fiber of embodiment 1, wherein the alkylene oxide-containing nonionic surfactant has a melting point of at least 30°C (or at least 40°C, or at least 50°C).

[0103] Embodiment 3 is the fiber of embodiment 1 or 2, wherein the alkylene oxide-containing nonionic surfactant has an average molecular weight of at least 900 g / mole (or at least 1000 g / mole, or at least 4000 g / mole Moore).

[0104] Embodiment 4 is the fiber of any one of the preceding embodiments, wherein the alkylene oxide-containing nonionic surfactant has an average molecular weight of at most 5000 grams / mole.

[0105] Embodiment 5 is the fiber of any one of the...

Embodiment 1-13 and comparative example 1-5

[0230] Meltblown nonwovens were prepared from polyester or nylon-6 matrix polymer resins extruded with different types and concentrations of surfactant additives. For comparison, meltblown nonwoven fabrics were prepared from polypropylene polymer resins extruded with different types and concentrations of surfactant additives. A meltblown nonwoven fabric without any surfactant additive was prepared as a control sample.

[0231] Examples of meltblown nonwoven fabrics are found in, for example, van Wente, "Superfine Thermoplastic Fibers", Industrial Engineering Chemistry, Vol. 48, pages 1342 et al. sec (1956)) or van Wente, A., Boone, C.D. and Fluharty, E.L., Naval Research Laboratory Report No. 4364, entitled "Manufacture of Ultrafine Organic Fibers", published May 25, 1954 (Report Experimental meltblown in-line extrusion taught in No. 4364 of the Naval Research Laboratories, published May 25, 1954 entitled "Manufacture of Superfine Organic Fibers" by van Wente, A., Boone, C.D....

Abstract

A fiber comprising: a base polymer comprising an aromatic polyester or nylon-6; and an alkylene oxide-containing nonionic surfactant mixed within the base polymer; wherein the alkylene oxide-containing nonionic surfactant has a melting point of greater than 25 DEG C and an HLB of greater than 10. An article comprising a plurality of said fibers, wherein a dye is present in a greater amount in a first portion of the fibers than in other portions of the fibers of the article.

Description

Background technique [0001] Thermal comfort depends on the heat released from the body. Moisture release is one mechanism of heat loss. During intense physical activity, a person's apocrine and eccrine sweat glands lose an average of 1200 milliliters (mL) of sweat per hour during strenuous activity. Cotton absorbs this perspiration (eg, 7.0-8.5% moisture regain at 65% relative humidity (RH)), while polyester and nylon, which are more hydrophobic in nature, do not. For example, polyester fabrics can only hold 0.4% moisture at 65% RH. [0002] The rate at which water vapor moves through a fabric plays an important role in determining human comfort as it affects the perception of cold / warm and aids in regulating body temperature. This process is called moisture vapor penetration or wicking. [0003] The vast majority of sportswear is made of polyester or nylon, which do not allow moisture to stay on their surface due to the hydrophobic nature of polyester or nylon, and steam ...
