KR880000945B1 - Tackified gloves - Google Patents

Abstract

The glove has at least part of both inner and outer surfaces tackified and at least part of the inner surface detackified so that it retains the feel of leather. The leather is pref. tackified through the material. The grove is pref. of unfilled, unfinished and chrome tanned calfskin, cowhide, cabretta or pigskin and is tackified with a synthetic copolymer together with a polymerised hydrocarbon resin with naphtha, heptane or other nonpolar organic solvent. The leather is pref. impregnated by immersion for 1-2 mins. then hanging to dry at room temp. under slow air fans.

Description

Sticky gloves

The present invention relates to a method for producing sports or work leather gloves having improved adhesion and the gloves themselves. Areas where safe gripping is important, such as golf and racquet balls. Polyurethanes and latexes and various coatings have been used to provide gloves for use in tennis, squash, soccer, football, baseball and the like.

German Patent Publication No. 28 40 179 proposes to coat a viscous material on the surface of a glove using an adhesive spray. However, this prior art was not entirely satisfactory. Lack of urethane and the necessary viscosity or coefficient of friction and failure to maintain the "feel" of the leather. On the other hand, adhesive coatings applied in the form of sprays tend to lack durability and tend to deteriorate the quality of the leather. Accordingly, it is an object of the present invention to provide a leather glove having adhesiveness without the drawbacks of the prior art.

Another object of the present invention is to provide a tackified leather glove washable with soap or detergent without reducing or removing the tackifying composition. It is still another object of the present invention to provide a leather glove having tackiness that the tackifying composition extends the life of the glove and preserves the glove. These and other objects are attained by the present invention in which all or part of the leather is saturated with thermoplastic unsaturated aromatic hydrocarbon resins derived from the petroleum hot fractionation process. In this process, saturation can be achieved by immersing the leather in a resin and low aromatic mineral spirit solution for 1-2 minutes.

In the result of such processing,

A. The surface texture of the gloves will be significantly increased than other leather gloves, providing a firm grip for grip purposes.

B. Gloves may be washed with soap or detergent without reducing or removing the tackifying composition.

C. This composition will protect the gloves from drying and deterioration due to use and will increase the strength of the leather against wear and tear.

C. The composition provides a barrier in the leather fibers to prevent sweating from the hands through which sweating is usually a barrier to safe gripping.

E. The treated area of the glove will show increased tack or coefficient of friction when subjected to moisture, high or low temperatures. It will also return to its original tacky texture after the moisture has been removed.

수지와 연화점이 낮거나 중간정도인 테르핀탄화수소수지를 예로 들수 있다. 이들 수지는 액체, 반고체 또는 고체의 형태이다. 용액을 준비하기 위한 용제의 예로서는 VM&P 나프타, Stoddard's 용액, 헵탄 또는 다른 저방향 미네랄 스피리트를 들 수 있다.This treatment method of the present invention can be applied to a variety of leather, such as sheep leather, cowhide, calf, pig leather, etc., the leather is preferably treated with chromium tannin so that the surface of the leather soaks into the resin solution It is not preprocessed. Resins for resin solutions are, for example, thermoplastic unsaturated aromatic hydrocarbon resins derived from high temperature fractionation of petroleum. Examples of such resins are Piccolyte, such as S55-S70, S85, S10, S25, manufactured by Herculus, Waltington City Street, 910, Delaware.

An example is a terpin hydrocarbon resin with a low or moderate softening point. These resins are in the form of liquids, semisolids or solids. Examples of solvents for preparing a solution include VM & P naphtha, Stoddard's solution, heptane or other low aromatic mineral spirits.

The following is a representative technique for treating leather for gloves according to the present invention.

EXAMPLE

Piccolyts S70 resin with specific gravity 0.950 was dissolved in sufficient amount of VM & P naphtha to obtain a solution with specific gravity of 0.770 at 22 ° C.

The palm of the leather glove was immersed in the solution at room temperature and allowed to stand in solution for 1-2 minutes. The palms are removed from the solution, dried at room temperature to allow the solvent to evaporate and sealed with gloves.

The inner fingers of the glove are also treated in this way. Such a technique can be variously modified by those skilled in the art without departing from the spirit and scope of the invention.
