Abstract

The invention relates to the technical field of textile, and discloses deer skin-like velvet socks and a preparation method thereof, wherein the method comprises the following steps: weaving sock blanks, dyeing, preparing temperature-adaptive multi-element synergistic post-treatment liquid, padding, drying, shaping, post-finishing and the like. The post-treatment liquid is formed by the cooperation of seven components of phospholipid compounds, sodium alginate, xanthan gum, fatty alcohol polyoxyethylene ether, lanolin derivatives, medium chain triglycerides and plant sterol esters, a double-layer structure of an elastic bottom layer and a soft surface layer is formed on the surface of the fiber, and low-temperature freezing resistance and high-temperature stability are respectively provided through the medium chain triglycerides and the plant sterol esters, so that temperature self-adaptive regulation and control are realized. The invention solves the technical problems of insufficient suede fullness, easy lodging of nap, uneven treatment and poor temperature adaptability of the existing deer leather-like nap socks, and ensures that the socks keep stable suede effect and soft hand feeling within a wide temperature range from-5 ℃ to 45 ℃.

Description

Deer skin-like velvet sock and preparation method thereof Technical Field The invention relates to the technical field of textile, in particular to deer skin-like velvet socks and a preparation method thereof. Background The deer skin-like velvet sock is a product with higher added value in the hosiery market, and is characterized in that the surface of the deer skin-like velvet sock has a plump and fine velvet effect and soft and comfortable hand feeling, and is similar to the touch feeling of natural deer skin. The preparation of such products usually employs a process route of weaving, shaping, dyeing and finishing, wherein the finishing process plays a decisive role in the pile effect and hand feel of the final product. The existing deer skin-like velvet sock preparation technology mainly adopts a single or a few chemical softeners to carry out post-treatment on sock blanks, but has the following technical problems: First, pile face fullness is insufficient. The traditional treatment method is difficult to make the microvilli on the fiber surface fully fluffy and directionally arranged, the treated sock has insufficient suede flatness and poor stereoscopic impression, the suede fluffiness is only 40-60% of that of the natural deer skin, and the plump suede effect of the natural deer skin cannot be presented. Secondly, the fluff is prone to lodging and handling non-uniformity. The fluff treated by the single auxiliary agent lacks an effective supporting structure, is easy to lodge in the wearing and washing processes, and the suede effect is attenuated by more than 50% after 10 times of washing. Meanwhile, the dispersibility of the hydrophobic component (such as lipid softener) and the hydrophilic component in the treatment liquid is poor, so that the sock surface treatment is uneven, the color and the hand feeling are different, and the consistency of the product quality is affected. Most critical is poor temperature adaptability. Lipid components in the existing treatment system can solidify and harden in a low-temperature environment (0-10 ℃) to enable a suede to lose soft hand feeling and rebound resilience, the lipid components are too strong in fluidity and possibly migrate in a high-temperature environment (30-40 ℃) to cause uneven suede treatment, and in an environment with a large day-night temperature difference, a lipid layer repeatedly undergoes solid-liquid phase transition to generate fatigue cracks, and the suede modification effect is attenuated. The product has stable suede effect and soft hand feeling in different seasons in spring, summer, autumn and winter and different regions in the north and south.
